to influence a procurement process or the execution of a contract

13.1. Unless otherwise stated in the BDS, the financial component of the bid shall

contain the following:

a) Financial Bid Form in accordance with the form prescribed in Section

IX. Bidding Forms indicating lump sum bid prices, which shall include

the detailed engineering costs;

b) Detailed estimates (Price Schedules/Bill of Quantities) including a

summary sheet indicating the unit prices of construction materials, labor

rates and equipment rentals used in coming up with the bid;

c) Cash flow by the quarter and payment schedules; and

d) Any other document related to the financial component of the bid as

stated in the BDS.

13.2. (a) Unless indicated in the BDS, all Bids that exceed the ABC shall not be

accepted.

(b) Unless otherwise indicated in the BDS, for foreign-funded

procurement, a ceiling may be applied to bid prices provided the

following conditions are met:

(i) Bidding Documents are obtainable free of charge on a freely

accessible website. If payment of Bidding Documents is required

by the procuring entity, payment could be made upon the

submission of bids.

(ii) The procuring entity has procedures in place to ensure that the ABC

is based on recent estimates made by the engineer or the

responsible unit of the procuring entity and that the estimates are

based on adequate detailed engineering (in the case of works) and

reflect the quality, supervision and risk and inflationary factors, as

well as prevailing market prices, associated with the types of

works or goods to be procured.

(iii) The procuring entity has trained cost estimators on estimating prices

and analyzing bid variances. In the case of infrastructure projects,

the procuring entity must also have trained quantity surveyors.

(iv) The procuring entity has established a system to monitor and report

bid prices relative to ABC and engineer’s/procuring entity’s

estimate.

21

(v) The procuring entity has established a monitoring and evaluation

system for contract implementation to provide a feedback on

actual total costs of goods and works.

14. Alternative Bids

14.1. Alternative Bids shall be rejected. For this purpose, alternative bid is an offer

made by a Bidder in addition or as a substitute to its original bid which may be

included as part of its original bid or submitted separately therewith for purposes

of bidding. A bid with options is considered an alternative bid regardless of

whether said bid proposal is contained in a single envelope or submitted in two

(2) or more separate bid envelopes.

14.2. Bidders shall submit offers that comply with the requirements of the Bidding

Documents, including the basic technical design as indicated in the drawings

and specifications. Unless there is a value engineering clause in the BDS,

alternative bids shall not be accepted.

14.3. Each Bidder shall submit only one Bid, either individually or as a partner in a

JV. A Bidder who submits or participates in more than one bid (other than as a

subcontractor if a subcontractor is permitted to participate in more than one bid)

will cause all the proposals with the Bidder’s participation to be disqualified.

This shall be without prejudice to any applicable criminal, civil and

administrative penalties that may be imposed upon the persons and entities

concerned.

15. Bid Prices

15.1 The contract shall be for the whole Works, which is design and build, based on

Price Schedules/Bill of Quantities for the detailed engineering design, and for

the construction of the works submitted by the Bidder. Bidders shall quote for

the entire design and build contract on a “single responsibility” basis such that

the total bid prices covers all the Contractor’s obligations mentioned in or to be

reasonably inferred from the Bidding Documents in respect to design and

construction of the project. The obligations of the Contractor include, but not

limited to, acquisition of all permits, approvals and licenses, etc.; and, any and

all such items and services as maybe specified in the Bidding Documents, all in

accordance with the requirements of the General Conditions of Contract. Items

against which, no price is entered by the Bidder will not be paid for by the

Procuring Entity when executed and shall be deemed to be covered by the prices

for other items.

15.2 The Bidder shall fill in rates and prices for all items of the Works, which is

design and build, described in the Price Schedules/Bill of Quantities to be

submitted by the Bidder. The Bidder shall identify and enumerate any and all

items of Works, which is design and build, and fill-in the pertinent quantities,

unit rates, and prices. Bids not addressing or providing all of the required items

of works in the Price Schedules/Bill of Quantities including, where applicable,

Price Schedules/Bill of Quantities, shall be considered non-responsive and, thus,

automatically disqualified. In this regard, where a required item is provided, but

no price is indicated, the same shall be considered as non-responsive, but

22

specifying a “0” (zero) for the said item would mean that it is being offered for

free to the Government.

15.3 All duties, taxes, and other levies payable by the Contractor under the Contract,

or for any other cause, prior to the deadline for submission of bids, shall be

included in the rates, prices, and total bid price submitted by the Bidder.

15.4 All bid prices for the given scope of work in the contract as awarded shall be

considered as fixed prices, and therefore not subject to price escalation during

contract implementation, except under extraordinary circumstances as specified

in GCC Clause 48. Price escalation may be allowed in extraordinary

circumstances as may be determined by the National Economic and

Development Authority in accordance with the Civil Code of the Philippines,

and upon the recommendation of the Procuring Entity. Furthermore, in cases

where the cost of the awarded contract is affected by any applicable new laws,

ordinances, regulations, or other acts of the GOP, promulgated after the date of

bid opening, a contract price adjustment shall be made or appropriate relief shall

be applied on a no loss-no gain basis.

16. Bid Currencies

16.1. All bid prices shall be quoted in Philippine Pesos unless otherwise provided in

the BDS. However, for purposes of bid evaluation, bids denominated in foreign

currencies shall be converted to Philippine currency based on the exchange rate

prevailing on the day of the Bid opening.

16.2. If so allowed in accordance with ITB Clause 16.1, the Procuring Entity for

purposes of bid evaluation and comparing the bid prices will convert the

amounts in various currencies in which the bid price is expressed to Philippine

Pesos at the exchange rate as published in the BSP reference rate bulletin on the

day of the bid opening.

16.3. Unless otherwise specified in the BDS, payment of the contract price shall be

made in Philippine Peso.

17. Bid Validity

17.1. Bids shall remain valid for the period specified in the BDS which shall not

exceed one hundred twenty (120) calendar days from the date of the opening of

bids.

17.2. In exceptional circumstances, prior to the expiration of the bid validity period,

the Procuring Entity may request Bidders to extend the period of validity of

their bids. The request and the responses shall be made in writing. The bid

security described in ITB Clause 18 should also be extended corresponding to

the extension of the bid validity period at the least. A Bidder may refuse the

request without forfeiting its bid security, but his bid shall no longer be

considered for further evaluation and award. A Bidder granting the request shall

not be required or permitted to modify its bid.

18. Bid Security

23

18.1. The bid security in the amount stated in the BDS shall be equal to the percentage

of the ABC in accordance with the following schedule:

Form of Bid Security Amount of Bid Security

(Equal to Percentage of the ABC)

(a) Cash or cashier’s/manager’s

check issued by a Universal or

Commercial Bank.

For biddings conducted by local government units, the Bidder may also submit

bid securities in the form of cashier’s/manager’s check, bank draft/guarantee, or

irrevocable letter of credit from other banks certified by the BSP as authorized

to issue such financial statement.

The Bid Securing Declaration mentioned above is an undertaking which states,

among others, that the bidder shall enter into contract with the procuring entity

and furnish the performance security required under ITB Clause 32.2, from

receipt of the Notice of Award, and committing to pay the corresponding fine,

and be suspended for a period of time from being qualified to participate in any

government procurement activity in the event it violates any of the conditions

stated therein as provided in the guidelines issued by the GPPB.

18.2. The bid security should be valid for the period specified in the BDS. Any bid

not accompanied by an acceptable bid security shall be rejected by the Procuring

Entity as non-responsive.

18.3. No bid securities shall be returned to bidders after the opening of bids and before

contract signing, except to those that failed or declared as post-disqualified,

upon submission of a written waiver of their right to file a motion for

reconsideration and/or protest. Without prejudice on its forfeiture, Bid

Securities shall be returned only after the bidder with the Lowest Calculated

Responsive Bid has signed the contract and furnished the Performance Security,

24

but in no case later than the expiration of the Bid Security validity period

indicated in ITB Clause 18.2.

18.4. Upon signing and execution of the contract, pursuant to ITB Clause 31, and the

posting of the performance security, pursuant to ITB Clause 32, the successful

Bidder’s Bid security will be discharged, but in no case later than the Bid

security validity period as indicated in ITB Clause 18.2.

18.5. The bid security may be forfeited:

(a) if a Bidder:

(i) withdraws its bid during the period of bid validity specified in

ITB Clause 17;

(ii) does not accept the correction of errors pursuant to ITB Clause

27.3(b);

(iii) fails to submit the requirements within the prescribed period, or

a finding against their veracity, as stated in ITB Clause 28.2;

(3) times within a year, except for valid reasons.

(b) if the successful Bidder:

(i) fails to sign the contract in accordance with ITB Clause 31;

(ii) fails to furnish performance security in accordance with ITB

Clause 32.

19. Format and Signing of Bids

19.1. Bidders shall submit their bids through their duly authorized representative

using the appropriate forms provided in Section IX. Bidding Forms on or before

the deadline specified in the ITB Clause 21 in two (2) separate sealed bid

envelopes, and which shall be submitted simultaneously. The first shall contain

the technical component of the bid, including the eligibility requirements under

ITB Clause 12.1, and the second shall contain the financial component of the

bid.

19.2. Forms as mentioned in ITB Clause 19.1 must be completed without any

alterations to their format, and no substitute form shall be accepted. All blank

spaces shall be filled in with the information requested.

19.3. The Bidder shall prepare an original of the first and second envelopes as

described in ITB Clauses 12 and 13. In addition, the Bidder shall submit copies

of the first and second envelopes. In the event of any discrepancy between the

original and the copies, the original shall prevail.

19.4. The bid, except for unamended printed literature, shall be signed, and each and

every page thereof shall be initialed, by the duly authorized representative/s of

the Bidder.

19.5. Any interlineations, erasures, or overwriting shall be valid only if they are

signed or initialed by the duly authorized representative/s of the Bidder.

20. Sealing and Marking of Bids

20.1. Bidders shall enclose their original eligibility and technical documents

described in ITB Clause 12, in one sealed envelope marked “ORIGINAL -

TECHNICAL COMPONENT”, and the original of their financial component

in another sealed envelope marked “ORIGINAL - FINANCIAL

COMPONENT”, sealing them all in an outer envelope marked “ORIGINAL

BID”.

20.2. Each copy of the first and second envelopes shall be similarly sealed duly

marking the inner envelopes as “COPY NO. ___ - TECHNICAL

COMPONENT” and “COPY NO. ___ – FINANCIAL COMPONENT” and the

outer envelope as “COPY NO. ___”, respectively. These envelopes containing

the original and the copies shall then be enclosed in one single envelope.

26

20.3. The original and the number of copies of the Bid as indicated in the BDS shall

be typed or written in indelible ink and shall be signed by the bidder or its duly

authorized representative/s.

20.4. All envelopes shall:

20.5. If bids are not sealed and marked as required, the Procuring Entity will assume

no responsibility for the misplacement or premature opening of the bid.

D. Submission and Opening of Bids

21. Deadline for Submission of Bids

Bids must be received by the Procuring Entity’s BAC at the address and on or before

the date and time indicated in the BDS.

22. Late Bids

Any bid submitted after the deadline for submission and receipt of bids prescribed by

the Procuring Entity, pursuant to ITB Clause 21, shall be declared “Late” and shall not

be accepted by the Procuring Entity.

23. Modification and Withdrawal of Bids

23.1. The Bidder may modify its bid after it has been submitted; provided that the

modification is received by the Procuring Entity prior to the deadline prescribed

for submission and receipt of bids. The Bidder shall not be allowed to retrieve

its original bid, but shall be allowed to submit another bid equally sealed,

properly identified, linked to its original bid marked as “TECHNICAL

MODIFICATION” or “FINANCIAL MODIFICATION” and stamped

“received” by the BAC. Bid modifications received after the applicable deadline

shall not be considered and shall be returned to the Bidder unopened.

23.2. A Bidder may, through a letter of withdrawal, withdraw its bid after it has been

submitted, for valid and justifiable reason; provided that the letter of withdrawal

is received by the Procuring Entity prior to the deadline prescribed for

submission and receipt of bids.

27

23.3. Bids requested to be withdrawn in accordance with ITB Clause 23.1 shall be

returned unopened to the Bidders. A Bidder may also express its intention not

to participate in the bidding through a letter which should reach and be stamped

by the BAC before the deadline for submission and receipt of bids. A Bidder

that withdraws its bid shall not be permitted to submit another bid, directly or

indirectly, for the same contract.

23.4. No bid may be modified after the deadline for submission of bids. No bid may

be withdrawn in the interval between the deadline for submission of bids and

the expiration of the period of bid validity specified by the Bidder on the

Financial Bid Form. Withdrawal of a bid during this interval shall result in the

forfeiture of the Bidder’s bid security, pursuant to ITB Clause 18.5, and the

imposition of administrative, civil, and criminal sanctions as prescribed by RA

9184 and its IRR.

24. Opening and Preliminary Examination of Bids

24.1. A two-steps procedure shall be undertaken by the Procuring Entity, which may

be undertaken with the assistance of the Design and Build Committee (DBC) or

with the Procuring Entity’s Engineer (Project Consultant).

24.2. First Step Procedure - The BAC shall open the first bid envelopes of Bidders in

public as specified in the BDS to determine each Bidder’s compliance with the

documents prescribed in ITB Clause 12. For this purpose, the BAC shall check

the submitted documents of each bidder against a checklist of required

documents to ascertain if they are all present, using a non-discretionary

“pass/fail” criterion. If a bidder submits the required document, it shall be rated

“passed” for that particular requirement. In this regard, bids that fail to include

any requirement or are incomplete or patently insufficient shall be considered

as “failed”. Otherwise, the BAC shall rate the said first bid envelope as

“passed”.

All the bids which are rated “passed” shall be then subjected to detailed

evaluation involving the review of the preliminary conceptual designs and track

record submitted by the Bidder, as required in ITB Clause 12.1(a) (iii) and

12.1(b) (ii), using the non-discretionary “pass/fail” criteria that involved

compliance with the following requirements:

a) Compliance with required design and construction experience;

b) Quality of personnel to be assigned to the project which covers suitability

of key staff to perform the duties of the particular assignment and general

qualifications and competence including education and training of the key

staff;

c) Adherence of preliminary design plans to the required performance

specifications and parameters and degree of details specified by the

Procuring Entity that will enable the quantities to be estimated and verified

up to plus/minus fifteen percent (+/-15%) of the final quantities;

d) Concept of approach and methodology for detailed engineering design,

supervisions and construction with emphasis to clarity, feasibility,

28

innovativeness and comprehensiveness of the plan approach, and the

quality of interpretation of project problems, risk, and suggested solutions;

e) Suitability of Design and Construction Schedules;

f) Value engineering analysis of design and construction methods to be

implemented; and

g) Suitability of contractor’s equipment units, which are owned, leased,

and/or under purchase agreements, supported by certification of

availability of equipment from the equipment lessor/vendor for the duration

of the project.

24.3 Second Step Procedure - Only those bids that passed the above criteria indicated

in the First Step Procedure shall be subjected to the Second Step Procedure.

Unless otherwise specified in the BDS, the BAC shall forthwith open the second

(financial) envelope of each remaining eligible bidder whose first envelope

passed the criteria of the First Step Procedure. In case one or more of the

requirements in the second envelope of a particular bid is missing, incomplete

or patently insufficient, and/or if the submitted total bid price exceeds the ABC

unless otherwise provided in ITB Clause 13.1(b), the BAC shall rate the bid

concerned as “failed”. Only bids that are determined to contain all the bid

requirements for both components shall be rated “passed” and shall immediately

be considered for evaluation and comparison.

24.4 Letters of withdrawal shall be read out and recorded during bid opening, and the

envelope containing the corresponding withdrawn bid shall be returned to the

Bidder unopened. If the withdrawing Bidder’s representative is in attendance,

the original bid and all copies thereof shall be returned to the representative

during the bid opening. If the representative is not in attendance, the Bid shall

be returned unopened by registered mail. The Bidder may withdraw its bid prior

to the deadline for the submission and receipt of bids, provided that the

corresponding letter of withdrawal contains a valid authorization requesting for

such withdrawal, subject to appropriate administrative sanctions.

24.5 If a Bidder has previously secured a certification from the Procuring Entity to

the effect that it has previously submitted the above-enumerated Class “A”

Documents, the said certification may be submitted in lieu of the requirements

enumerated in ITB Clause 12.1(a), items (i) to (vi).

24.6 In the case of an eligible foreign Bidder as described in ITB Clause 5, the Class

“A” Documents enumerated in ITB Clause 12.1(a) may be substituted with the

appropriate equivalent documents, if any, issued by the country of the foreign

Bidder concerned.

24.7 Each partner of a joint venture agreement shall likewise submit the documents

required in ITB Clauses 12.1(a) (i) and 12.1(a)(ii). Submission of documents

required under ITB Clauses 12.1 (a)(iii) to 12.1 (a)(vi) by any of the joint

venture partners constitutes compliance.

24.8 A Bidder determined as “failed” has three (3) calendar days upon written notice

or, if present at the time of bid opening, upon verbal notification within which

to file a request for reconsideration with the BAC: Provided, however, that the

29

request for reconsideration shall not be granted if it is established that the finding

of failure is due to the fault of the Bidder concerned: Provided, further, that the

BAC shall decide on the request for reconsideration within seven (7) calendar

days from receipt thereof. If a failed Bidder signifies his intent to file a request

for reconsideration, the BAC shall keep the bid envelopes of the said failed

Bidder unopened and/or duly sealed until such time that the request for

reconsideration or protest has been resolved.

24.9 The Procuring Entity shall prepare the minutes of the proceedings of the bid

opening that shall include, as a minimum: (a) names of Bidders, their bid price,

bid security, findings of preliminary examination; and (b) attendance sheet. The

BAC members shall sign the abstract of bids as read.

E. Evaluation and Comparison of Bids

25. Process to be Confidential

25.1 Members of the BAC, including its staff and personnel, as well as its Secretariat

and TWG, are prohibited from making or accepting any kind of communication

with any bidder regarding the evaluation of their bids until the issuance of the

Notice of Award, unless n the case of ITB Clause 26.

25.2 Any effort by a bidder to influence the Procuring Entity in the Procuring Entity’s

decision in respect of Bid evaluation, Bid comparison or contract award will

result in the rejection of the Bidder’s Bid.

26. Clarification of Bids

To assist in the evaluation, comparison and post-qualification of the bids, the Procuring

Entity may ask in writing any Bidder for a clarification of its bid. All responses to

requests for clarification shall be in writing. Any clarification submitted by a Bidder in

respect to its bid and that is not in response to a request by the Procuring Entity shall

not be considered

27. Detailed Evaluation and Comparison of Bids

27.1 The Procuring Entity will undertake the detailed evaluation and comparison of

Bids which have passed the opening and preliminary examination of Bids,

pursuant to ITB Clause 24, in order to determine the Lowest Calculated Bid.

27.2 In evaluating the Bids to get the Lowest Calculated Bid, the Procuring Entity

shall undertake the following:

a) The detailed evaluation of the financial component of the bids, to

establish the correct calculated prices of the bids; and

b) The ranking of the total bid prices as so calculated from the lowest to

highest. The bid with the lowest price shall be identified as the Lowest

Calculated Bid.

30

27.3 The Procuring Entity's BAC shall immediately conduct a detailed evaluation of

all bids rated “passed,” using non-discretionary “pass/fail” criterion. The BAC

shall consider the following in the evaluation of bids:

a) Completeness of the bid. Unless the ITB specifically allows partial bids,

bids not addressing or providing all of the required items in the Schedule

of Requirements including, where applicable, bill of quantities, shall be

considered non-responsive and, thus, automatically disqualified. In this

regard, where a required item is provided, but no price is indicated, the

same shall be considered as non-responsive, but specifying a "0" (zero)

for the said item would mean that it is being offered for free to the

Procuring Entity; and,

b) Arithmetical corrections. Consider computational errors and omissions

to enable proper comparison of all eligible bids. It may also consider bid

modifications if expressly allowed in the BDS. Any adjustment shall be

calculated in monetary terms to determine the calculated prices.

27.4 Based on the detailed evaluation of bids, those that comply with the above-

mentioned requirements shall be ranked in the ascending order of their total

calculated bid prices, as evaluated and corrected for computational errors,

discounts and other modifications, to identify the Lowest Calculated Bid. Total

calculated bid prices, as evaluated and corrected for computational errors,

discounts and other modifications, which exceed the ABC shall not be

considered, unless otherwise indicated in the BDS.

27.5 The Procuring Entity’s evaluation of bids shall only be based on the bid price

quoted in the Financial Bid Form

27.6 Bids shall be evaluated on an equal footing to ensure fair competition. For this

purpose, all bidders shall be required to include in their bids the cost of all taxes,

such as, but not limited to, value added tax (VAT), income tax, local taxes, and

other fiscal levies and duties which shall be itemized in the bid form and

reflected in the detailed estimates. Such bids, including said taxes, shall be the

basis for bid evaluation and comparison.

28. Post Qualification

28.1 The Procuring Entity shall determine to its satisfaction whether the Bidder that

is evaluated as having submitted the Lowest Calculated Bid (LCB) complies

with and is responsive to all the requirements and conditions specified in ITB

Clauses 5, 12, and 13.

28.2 Within a non-extendible period of three (3) calendar days from receipt by the

Bidder of the notice from the BAC that it submitted the LCB, the Bidder shall

submit the following documentary requirements:

a) Latest income and business tax returns in the form specified in the BDS;

b) Certificate of PhilGEPS Registration or PhilGEPS Registration Number

if the procuring entity is a Philippine foreign office or post, provided that

31

participating bidders should register with the PhilGEPS prior to bid

opening; and

c) Other appropriate licenses and permits required by law and stated in the

BDS.

Failure of the Bidder declared as LCB to duly submit the requirements under

this Clause or a finding against the veracity of such, shall be ground for

forfeiture of the bid security and disqualification of the Bidder for award.

28.3 The determination shall be based upon an examination of the documentary

evidence of the Bidder’s qualifications submitted pursuant to ITB Clauses 12

and 13, as well as other information as the Procuring Entity deems necessary

and appropriate, using a non-discretionary “pass/fail” criterion.

28.4 If the BAC determines that the Bidder with the Lowest Calculated Bid passes

all the criteria for post-qualification, it shall declare the said bid as the Lowest

Calculated Responsive Bid, and recommend to the Head of the Procuring Entity

the award of contract to the said Bidder at its submitted price or its calculated

bid price, whichever is lower, subject to ITB Clause 30.3.

28.5 A negative determination shall result in rejection of the Bidder’s Bid, in which

event the Procuring Entity shall proceed to the next Lowest Calculated Bid to

make a similar determination of that Bidder’s capabilities to perform

satisfactorily. If the second Bidder, however, fails the post qualification, the

procedure for post qualification shall be repeated for the Bidder with the next

Lowest Calculated Bid, and so on until the Lowest Calculated and Responsive

Bid is determined for contract award.

28.6 Within a period not exceeding seven (7) calendar days from the date of receipt

of the recommendation of the BAC, the Head of the Procuring Entity shall

approve or disapprove the said recommendation. In the case of government

owned and government-owned and/or -controlled corporations (GOCCs) and

government financial institutions (GFIs), the period provided herein shall be

fifteen (15) calendar days.

29. Reservation Clause

29.1 Notwithstanding the eligibility or post-qualification of a bidder, the Procuring

Entity concerned reserves the right to review its qualifications at any stage of

the procurement process if it has reasonable grounds to believe that a

misrepresentation has been made by the said bidder, or that there has been a

change in the Bidder’s capability to undertake the project from the time it

submitted its eligibility requirements. Should such review uncover any

misrepresentation made in the eligibility and bidding requirements, statements

or documents, or any changes in the situation of the Bidder which will affect its

capability to undertake the project so that it fails the preset eligibility or bid

evaluation criteria, the Procuring Entity shall consider the said Bidder as

ineligible and shall disqualify it from submitting a bid or from obtaining an

award or contract.

32

29.2 Based on the following grounds, the Procuring Entity reserves the right to reject

any and all Bids, declare a Failure of Bidding at any time prior to the contract

award, or not to award the contract, without thereby incurring any liability, and

make no assurance that a contract shall be entered into as a result of the bidding:

a) if there is prima facie evidence of collusion between appropriate public

officers or employees of the Procuring Entity, or between the BAC and

any of the bidders, or if the collusion is between or among the bidders

themselves, or between a bidder and a third party, including any act

which restricts, suppresses or nullifies or tends to restrict, suppress or

nullify competition;

b) if the Procuring Entity’s BAC is found to have failed in following the

prescribed bidding procedures; or

c) for any justifiable and reasonable ground where the award of the contract

will not redound to the benefit of the Government as follows:

i) If the physical and economic conditions have significantly

changed so as to render the project no longer economically,

financially or technically feasible as determined by the head of

the procuring entity;

ii) If the project is no longer necessary as determined by the head

of the procuring entity; and

iii) If the source of funds for the project has been withheld or

reduced through no fault of the Procuring Entity.

29.3 In addition, the Procuring Entity may likewise declare a failure of bidding when:

a) No bids are received;

b) All prospective bidders are declared ineligible;

c) All bids fail to comply with all the bid requirements or fail post-

qualification; or,

d) The bidder with the Lowest Calculated Responsive Bid refuses, without

justifiable cause to accept the award of contract, and no award is made.

F. Award of Contract

30. Contract Award

30.1 Subject to ITB Clause 28, the Procuring Entity shall award the contract to the

Bidder whose Bid has been determined to be the Lowest Calculated and

Responsive Bid (LCRB).

30.2 Prior to the expiration of the period of Bid validity, the Procuring Entity shall

notify the successful Bidder in writing that its Bid has been accepted, through a

Notice of Award received personally or sent by registered mail or electronically,

33

receipt of which must be confirmed in writing within two (2) days by the LCRB

and submitted personally or sent by registered mail or electronically to the

Procuring Entity.

30.3 Notwithstanding the issuance of the Notice of Award, award of contract shall be

subject to the following conditions:

a) Submission of the following documents within the prescribed period

from receipt by the Bidder of the notice that it has the Lowest Calculated

and Responsive Bid:

i) Valid JVA, if applicable, within ten (10) calendar days;

ii) Valid PCAB license and registration for the type and cost of the

contract to be bid for foreign bidders, within thirty (30) calendar

Procuring Entity, they are incorporated in the Contract Price and treated as a

Variation.

26. Extension of the Intended Completion Date

26.1. The Procuring Entity’s Representative shall extend the Intended Completion

Date if a Variation is issued which makes it impossible for the Intended

Completion Date to be achieved by the Contractor without taking steps to

accelerate the remaining work, which would cause the Contractor to incur

additional costs. No payment shall be made for any event which may warrant

the extension of the Intended Completion Date.

26.2. The Procuring Entity’s Representative shall decide whether and by how much

to extend the Intended Completion Date within twenty-one (21) days of the

Contractor asking the Procuring Entity’s Representative for a decision thereto

after fully submitting all supporting information. If the Contractor has failed to

give early warning of a delay or has failed to cooperate in dealing with a delay,

the delay by this failure shall not be considered in assessing the new Intended

Completion Date.

27. Right to Vary

27.1. The Procuring Entity’s Representative with the prior approval of the Procuring

Entity may instruct Variations, up to a maximum cumulative amount of ten

Procuring Entity.

28. Contractor's Right to Claim

If the Contractor incurs cost as a result of any of the events under GCC Clause 13, the

Contractor shall be entitled to the amount of such cost. If as a result of any of the said

events, it is necessary to change the Works, this shall be dealt with as a Variation.

29. Dayworks

29.1. Subject to GCC Clause 43 on Variation Order, and if applicable as indicated in

the SCC, the Dayworks rates in the Contractor’s Bid shall be used for small

additional amounts of work only when the Procuring Entity’s Representative

remaining work, including any changes to the sequence of the activities.

76

31.3. The Contractor shall submit to the Procuring Entity’s Representative for

approval an updated Program of Work at intervals no longer than the period

stated in the SCC. If the Contractor does not submit an updated Program of

Work within this period, the PROCURING ENTITY’s Representative may

withhold the amount stated in the SCC from the next payment certificate and

continue to withhold this amount until the next payment after the date on which

the overdue Program of Work has been submitted.

31.4. The Procuring Entity’s Representative’s approval of the Program of Work shall

not alter the Contractor’s obligations. The Contractor may revise the Program

of Work and submit it to the Procuring Entity’s Representative again at any

time. A revised Program of Work shall show the effect of any approved

Variations.

the Management Conference or after the Management Conference and stated in

writing to all who attended the Conference.

33. Bill of Quantities

33.1. The Bill of Quantities shall contain items of work for the construction,

installation, testing, and commissioning of work to be done by the Contractor.

33.2. The Bill of Quantities is used to calculate the Contract Price. The Contractor is

paid for the quantity of the work done at the rate in the Bill of Quantities for

each item.

33.3. If the final quantity of any work done differs from the quantity in the Bill of

Quantities for the particular item and is not more than twenty-five percent (25%)

of the original quantity, provided the aggregate changes for all items do not

exceed ten percent (10%) of the Contract price, the Procuring Entity’s

Representative shall make the necessary adjustments to allow for the changes

subject to applicable laws, rules, and regulations.

77

34.3. The Contractor shall permit the Funding Source named in the SCC to inspect

the Contractor’s accounts and records relating to the performance of the

Contractor and to have them audited by auditors appointed by the Funding

Source, if so required by the Funding Source.

Representative’s notice.

37.3. The Contractor shall correct the defects which he notices himself before the end

of the Defects Liability Period.

37.4. The Procuring Entity shall certify that all defects have been corrected. If the

Procuring Entity considers that correction of a defect is not essential, he can

request the Contractor to submit a quotation for the corresponding reduction in

78

the Contract Price. If the Procuring Entity accepts the quotation, the

corresponding change in the SCC is a Variation.

38. Uncorrected Defects

38.1. The Procuring Entity shall give the Contractor at least fourteen (14) days notice

of his intention to use a third party to correct a Defect. If the Contractor does

not correct the Defect himself within the period, the Procuring Entity may have

deducted from the Contract Price.

38.2. The use of a third party to correct defects that are uncorrected by the Contractor

will in no way relieve the Contractor of its liabilities and warranties under the

Contract.

39. Advance Payment

39.1. The Procuring Entity shall, upon a written request of the contractor which shall

be submitted as a contract document, make an advance payment to the

contractor in an amount not exceeding fifteen percent (15%) of the total contract

callable upon demand, issued by a surety or insurance company duly licensed

by the Insurance Commission and confirmed by the Procuring Entity.

39.3. The advance payment shall be repaid by the Contractor by an amount equal to

the percentage of the total contract price used for the advance payment.

request for payment shall be verified and certified by the Procuring Entity’s

Representative/Project Engineer. Except as otherwise stipulated in the SCC,

materials and equipment delivered on the site but not completely put in place

shall not be included for payment.

40.2. The Procuring Entity shall deduct the following from the certified gross

amounts to be paid to the contractor as progress payment:

(a) Cumulative value of the work previously certified and paid for.

79

(b) Portion of the advance payment to be recouped for the month.

(c) Retention money in accordance with the condition of contract.

(d) Amount to cover third party liabilities.

(e) Amount to cover uncorrected discovered defects in the works.

40.3. Payments shall be adjusted by deducting therefrom the amounts for advance

payments and retention. The Procuring Entity shall pay the Contractor the

(28) days from the date each certificate was issued. No payment of interest for

delayed payments and adjustments shall be made by the Procuring Entity.

40.4. The first progress payment may be paid by the Procuring Entity to the

Contractor provided that at least twenty percent (20%) of the work has been

accomplished as certified by the Procuring Entity’s Representative.

40.5. Items of the Works for which a price of “0” (zero) has been entered will not be

paid for by the Procuring Entity and shall be deemed covered by other rates and

prices in the Contract.

statements of the estimated value of the work executed less the cumulative

amount certified previously.

41.2. The Procuring Entity’s Representative shall check the Contractor’s monthly

statement and certify the amount to be paid to the Contractor.

amount equal to a percentage thereof using the rate as specified in ITB Sub-

Clause 42.2.

42.2. Progress payments are subject to retention of ten percent (10%), referred to as

the “retention money.” Such retention shall be based on the total amount due to

80

the Contractor prior to any deduction and shall be retained from every progress

payment until fifty percent (50%) of the value of Works, as determined by the

Procuring Entity, are completed. If, after fifty percent (50%) completion, the

Work is satisfactorily done and on schedule, no additional retention shall be

made; otherwise, the ten percent (10%) retention shall again be imposed using

the rate specified therefor.

42.3. The total “retention money” shall be due for release upon final acceptance of

the Works. The Contractor may, however, request the substitution of the

retention money for each progress billing with irrevocable standby letters of

credit from a commercial bank, bank guarantees or surety bonds callable on

demand, of amounts equivalent to the retention money substituted for and

acceptable to the Procuring Entity, provided that the project is on schedule and

is satisfactorily undertaken. Otherwise, the ten (10%) percent retention shall be

made. Said irrevocable standby letters of credit, bank guarantees and/or surety

bonds, to be posted in favor of the Government shall be valid for a duration to

be determined by the concerned implementing office/agency or Procuring

Entity and will answer for the purpose for which the ten (10%) percent retention

is intended, i.e., to cover uncorrected discovered defects and third party

liabilities.

42.4. On completion of the whole Works, the Contractor may substitute retention

money with an “on demand” Bank guarantee in a form acceptable to the

Procuring Entity.

43. Variation Orders

43.1. Variation Orders may be issued by the Procuring Entity to cover any

increase/decrease in quantities, including the introduction of new work items

that are not included in the original contract or reclassification of work items

that are either due to change of plans, design or alignment to suit actual field

conditions resulting in disparity between the preconstruction plans used for

purposes of bidding and the “as staked plans” or construction drawings prepared

after a joint survey by the Contractor and the Procuring Entity after award of

the contract, provided that the cumulative amount of the Variation Order does

not exceed ten percent (10%) of the original project cost. The addition/deletion

of Works should be within the general scope of the project as bid and awarded.

The scope of works shall not be reduced so as to accommodate a positive

Variation Order. A Variation Order may either be in the form of a Change Order

or Extra Work Order.

43.2. A Change Order may be issued by the Procuring Entity to cover any

increase/decrease in quantities of original Work items in the contract.

43.3. An Extra Work Order may be issued by the Procuring Entity to cover the

introduction of new work necessary for the completion, improvement or

protection of the project which were not included as items of Work in the

original contract, such as, where there are subsurface or latent physical

conditions at the site differing materially from those indicated in the contract,

or where there are duly unknown physical conditions at the site of an unusual

81

nature differing materially from those ordinarily encountered and generally

recognized as inherent in the Work or character provided for in the contract.

43.4. Any cumulative Variation Order beyond ten percent (10%) shall be subject of

another contract to be bid out if the works are separable from the original

contract. In exceptional cases where it is urgently necessary to complete the

original scope of work, the Head of the Procuring Entity may authorize a

positive Variation Order go beyond ten percent (10%) but not more than twenty

percent (20%) of the original contract price, subject to the guidelines to be

determined by the GPPB: Provided, however, That appropriate sanctions shall

be imposed on the designer, consultant or official responsible for the original

detailed engineering design which failed to consider the Variation Order beyond

ten percent (10%).

43.5. In claiming for any Variation Order, the Contractor shall, within seven (7)

calendar days after such work has been commenced or after the circumstances

leading to such condition(s) leading to the extra cost, and within twenty-eight

(28) calendar days deliver a written communication giving full and detailed

particulars of any extra cost in order that it may be investigated at that time.

Failure to provide either of such notices in the time stipulated shall constitute a

waiver by the contractor for any claim. The preparation and submission of

Variation Orders are as follows:

(a) If the Procuring Entity’s representative/Project Engineer believes that a

Change Order or Extra Work Order should be issued, he shall prepare

the proposed Order accompanied with the notices submitted by the

Contractor, the plans therefore, his computations as to the quantities of

the additional works involved per item indicating the specific stations

where such works are needed, the date of his inspections and

investigations thereon, and the log book thereof, and a detailed estimate

of the unit cost of such items of work, together with his justifications for

the need of such Change Order or Extra Work Order, and shall submit

the same to the Head of the Procuring Entity for approval.

(b) The Head of the Procuring Entity or his duly authorized representative,

upon receipt of the proposed Change Order or Extra Work Order shall

immediately instruct the technical staff of the Procuring Entity’s to

conduct an on-the-spot investigation to verify the need for the Work to

be prosecuted. A report of such verification shall be submitted directly

to the Head of the Procuring Entity or his duly authorized representative.

(c) The, Head of the Procuring Entity or his duly authorized representative,

after being satisfied that such Change Order or Extra Work Order is

justified and necessary, shall review the estimated quantities and prices

and forward the proposal with the supporting documentation to the Head

of Procuring Entity for consideration.

(d) If, after review of the plans, quantities and estimated unit cost of the

items of work involved, the proper office of the procuring entity

empowered to review and evaluate Change Orders or Extra Work Orders

recommends approval thereof, Head of the Procuring Entity or his duly

82

authorized representative, believing the Change Order or Extra Work

Order to be in order, shall approve the same.

(e) The timeframe for the processing of Variation Orders from the

preparation up to the approval by the Head of the Procuring Entity

concerned shall not exceed thirty (30) calendar days.

44. Contract Completion

Once the project reaches an accomplishment of ninety five (95%) of the total contract

amount, the Procuring Entity may create an inspectorate team to make preliminary

inspection and submit a punch-list to the Contractor in preparation for the final turnover

of the project. Said punch-list will contain, among others, the remaining Works, Work

deficiencies for necessary corrections, and the specific duration/time to fully complete

the project considering the approved remaining contract time. This, however, shall not

preclude the claim of the Procuring Entity for liquidated damages.

45. Suspension of Work

45.1. The Procuring Entity shall have the authority to suspend the work wholly or

partly by written order for such period as may be deemed necessary, due to force

majeure or any fortuitous events or for failure on the part of the Contractor to

correct bad conditions which are unsafe for workers or for the general public,

to carry out valid orders given by the Procuring Entity or to perform any

provisions of the contract, or due to adjustment of plans to suit field conditions

as found necessary during construction. The Contractor shall immediately

comply with such order to suspend the work wholly or partly.

45.2. The Contractor or its duly authorized representative shall have the right to

suspend work operation on any or all projects/activities along the critical path

of activities after fifteen (15) calendar days from date of receipt of written notice

from the Contractor to the district engineer/regional director/consultant or

equivalent official, as the case may be, due to the following:

(a) There exist right-of-way problems which prohibit the Contractor from

performing work in accordance with the approved construction

schedule.

(b) Requisite construction plans which must be owner-furnished are not

issued to the contractor precluding any work called for by such plans.

(c) Peace and order conditions make it extremely dangerous, if not possible,

to work. However, this condition must be certified in writing by the

Philippine National Police (PNP) station which has responsibility over

the affected area and confirmed by the Department of Interior and Local

Government (DILG) Regional Director.

(d) There is failure on the part of the Procuring Entity to deliver

government-furnished materials and equipment as stipulated in the

contract.

83

(e) Delay in the payment of Contractor’s claim for progress billing beyond

forty-five (45) calendar days from the time the Contractor’s claim has

been certified to by the procuring entity’s authorized representative that

the documents are complete unless there are justifiable reasons thereof

which shall be communicated in writing to the Contractor.

45.3. In case of total suspension, or suspension of activities along the critical path,

which is not due to any fault of the Contractor, the elapsed time between the

effective order of suspending operation and the order to resume work shall be

allowed the Contractor by adjusting the contract time accordingly.

46. Payment on Termination

46.1. If the Contract is terminated because of a fundamental breach of Contract by the

Contractor, the Procuring Entity’s Representative shall issue a certificate for the

value of the work done and Materials ordered less advance payments received

up to the date of the issue of the certificate and less the percentage to apply to

the value of the work not completed, as indicated in the SCC. Additional

Liquidated Damages shall not apply. If the total amount due to the Procuring

Entity exceeds any payment due to the Contractor, the difference shall be a debt

payable to the Procuring Entity.

46.2. If the Contract is terminated for the Procuring Entity’s convenience or because

of a fundamental breach of Contract by the Procuring Entity, the Procuring

Entity’s Representative shall issue a certificate for the value of the work done,

Materials ordered, the reasonable cost of removal of Equipment, repatriation of

the Contractor’s personnel employed solely on the Works, and the Contractor’s

costs of protecting and securing the Works, and less advance payments received

up to the date of the certificate.

46.3. The net balance due shall be paid or repaid within twenty-eight (28) days from

the notice of termination.

46.4. If the Contractor has terminated the Contract under GCC Clauses 17 or 18, the

Procuring Entity shall promptly return the Performance Security to the

Contractor.

47. Extension of Contract Time

47.1. Should the amount of additional work of any kind or other special circumstances

of any kind whatsoever occur such as to fairly entitle the contractor to an

extension of contract time, the Procuring Entity shall determine the amount of

such extension; provided that the Procuring Entity is not bound to take into

account any claim for an extension of time unless the Contractor has, prior to

the expiration of the contract time and within thirty (30) calendar days after such

work has been commenced or after the circumstances leading to such claim have

arisen, delivered to the Procuring Entity notices in order that it could have

investigated them at that time. Failure to provide such notice shall constitute a

waiver by the Contractor of any claim. Upon receipt of full and detailed

particulars, the Procuring Entity shall examine the facts and extent of the delay

84

and shall extend the contract time completing the contract work when, in the

Procuring Entity’s opinion, the findings of facts justify an extension.

47.2. No extension of contract time shall be granted the Contractor due to (a) ordinary

unfavorable weather conditions and (b) inexcusable failure or negligence of

Contractor to provide the required equipment, supplies or materials.

47.3. Extension of contract time may be granted only when the affected activities fall

within the critical path of the PERT/CPM network.

47.4. No extension of contract time shall be granted when the reason given to support

the request for extension was already considered in the determination of the

original contract time during the conduct of detailed engineering and in the

preparation of the contract documents as agreed upon by the parties before

contract perfection.

47.5. Extension of contract time shall be granted for rainy/unworkable days

considered unfavorable for the prosecution of the works at the site, based on the

actual conditions obtained at the site, in excess of the number of

rainy/unworkable days pre-determined by the Procuring Entity in relation to the

original contract time during the conduct of detailed engineering and in the

preparation of the contract documents as agreed upon by the parties before

contract perfection, and/or for equivalent period of delay due to major

calamities such as exceptionally destructive typhoons, floods and earthquakes,

and epidemics, and for causes such as non-delivery on time of materials,

working drawings, or written information to be furnished by the Procuring

Entity, non-acquisition of permit to enter private properties within the right-of-

way resulting in complete paralyzation of construction activities, and other

meritorious causes as determined by the Procuring Entity’s Representative and

approved by the Head of the Procuring Entity. Shortage of construction

materials, general labor strikes, and peace and order problems that disrupt

construction operations through no fault of the Contractor may be considered as

additional grounds for extension of contract time provided they are publicly felt

and certified by appropriate government agencies such as DTI, DOLE, DILG,

and DND, among others. The written consent of bondsmen must be attached to

any request of the Contractor for extension of contract time and submitted to the

Procuring Entity for consideration and the validity of the Performance Security

shall be correspondingly extended.

48. Price Adjustment

Except for extraordinary circumstances as determined by NEDA and approved by the

GPPB, no price adjustment shall be allowed. Nevertheless, in cases where the cost of

the awarded contract is affected by any applicable new laws, ordinances, regulations,

or other acts of the GOP, promulgated after the date of bid opening, a contract price

adjustment shall be made or appropriate relief shall be applied on a no loss-no gain

basis.

85

49. Completion

The Contractor shall request the Procuring Entity’s Representative to issue a certificate

of Completion of the Works, and the Procuring Entity’s Representative will do so upon

deciding that the work is completed.

50. Taking Over

The Procuring Entity shall take over the Site and the Works within seven (7) days from

the date the Procuring Entity’s Representative issues a certificate of Completion.

51. Operating and Maintenance Manuals

51.1. If “as built” Drawings and/or operating and maintenance manuals are required,

the Contractor shall supply them by the dates stated in the SCC.

51.2. If the Contractor does not supply the Drawings and/or manuals by the dates

stated in the SCC, or they do not receive the Procuring Entity’s Representative’s

approval, the Procuring Entity’s Representative shall withhold the amount

stated in the SCC from payments due to the Contractor.

2. MRT-3 SYSTEM DESCRIPTION

A. General

The MRT-3 System is the cornerstone of the Department of Transportation’s

(DOT) integrated strategy to alleviate the traffic congestion along the EDSA

corridor. Completed in July 2000, the MRT-3 is carrying a maximum of around

600, 000 passengers daily. The system is built by a private consortium, Metro Rail

Transit, Corp. (MRTC), under the Build, Lease and Transfer Agreement with the

for a period of 25 years.

B. Alignment

The line is a 16.9km rail system occupying the median of EDSA with 40% at-

grade, 52% elevated and 8% underground or depressed. Running from North

Avenue, Quezon City to Taft Avenue in Pasay City, the MRT-3 has a total of 9

elevated, 2 at-grade and 2 depressed stations with side platforms for elevated and

center platforms for depressed or at-grade stations.

C. Guideway

The total length of the MRT-3 guideway is about 16.9km consisting of the

Kalayaan Tunnel (515m), At-grade level (7000m), elevated structures (9000m) and

steel structure (135 m). It traverses along EDSA from North Avenue in Quezon

City to Taft Avenue in Pasay City, designed to fit the existing infrastructures like

the Magallanes and Ortigas Flyovers.

The elevated guideway structure was constructed using reinforced concrete except

for the Guadalupe Bridge, which is made of structural steel. The guideway supports

spaces for the Signaling, communication, high and low voltage power distribution

systems of the MRT-3. It is made of AASHTO pre-stressed girders with reinforced

concrete slab overlay of about 210mm thickness and supported by either column

piers or portal frame supports. All guideway foundations are generally bored piles.

All design and construction of the elevated guideway are in accordance with the

existing Philippines Standards and Code of Practice and/or international applicable

standards.

D. Tracks

The MRT-3 system uses a standard gauge track of 1435mm utilizing UIC 54 rail

profile welded together to form continuous rail using flash-butt and alumino-

thermic welding process for the mainline. Crossovers are located in North, Cubao,

Shaw, Buendia and Taft with an access track to and from the depot located between

North Avenue and Quezon Avenue Station.

The Mainline has a minimum horizontal radius of 370 m and applies an absolute

maximum gradient of 4.0%. For the Depot Access Track, an absolute gradient of

5% is present with zero cant all throughout the depot area and a minimum radius

of 25m in the depot curved sections.

The mainline track consists of both ballasted and concrete plinth sections.

Ballasted tracks are about 7.6km in distance, supported by concrete sleepers, with

750mm spacing. Rail fastening is made through the use of Rail Fastening System

laid on the ballast with at least 250 mm depth. Concrete plinth tracks are about

9.15 km long utilizing direct fixation fasteners with 750 mm spacing and supported

by a concrete plinth of 220 mm thickness.

Remote operation of point switches for crossovers at North, Taft, Shaw, Depot

Access Track and at the pocket track at Taft can be carried out from the Control

Center. Manual point switches are installed in Buendia and Cubao for maintenance

and emergency operation. Automatic point switches are fitted with position

detectors that can be monitored from the Control Center while manual point

switches are fitted with levers and locks only.

Current maximum train speed is at 40 kph and shall be increased to 65 kph after

track replacement/rehabilitation.

E. Stations

There are 13 stations along the 16.9-km stretch of the MRT-3 system. Station

platforms are designed to accommodate 4-car train operation with standard

platform length of at least 130m. It has two main areas: The Paid Concourse Area

that accommodates paid riding passengers; and Unpaid Concourse Area for

queuing passengers with commercial spaces, retail shops and other public services.

The two areas are divided by the fare collection gates structured to accommodate

future expansion. Each station is also equipped with facilities that cater to the

elderly and handicapped.

All stations are equipped with elevators (lifts) capable for serving handicapped and

elderly passengers. Internal escalators are installed inside the paid areas while

external escalators are provided in some elevated stations to access concourse areas

from street level.

F. Depot Facilities

A Depot that houses the Light Rail Vehicles is located adjacent to the North

Avenue station where the maintenance of LRV(s) is performed and trains are

stabled. It has a total area of 84,444m2 which houses the workshop and

maintenance facilities and has stabling capacity for 81 LRVs, with provisional

space available for additional 40 LRVs. It has facilities capable for light and heavy

maintenance works with office spaces for the operation and maintenance

management.

G. Rolling Stock

The MRT-3 system has a total fleet of seventy three (73) Light Rail Vehicles

(LRV’s), but four (4) LRVs are currently not in service. These are Cars 70, 73, 03,

and 08.

The LRV is built by CKD Doprovni Systemy of Prague. It is articulated in three-

sections with four bogies (eight axles), designed for single-ended operation. Each

has ten double-leaf, electronically-operated, plug-sliding doors (5 on each side),

with three center doors having an open width of 1,255mm and two end doors at

861 mm. Each LRV can seat a total of 74 passengers and can accommodate 320

standing passengers for a total of 394 passengers per LRV.

The cars are equipped with Automatic Train Protection System (ATP), which

collects information from wayside system through balises for the speed monitoring

and control. Each car has a Digital Diagnostic System that monitors the defects

and assists Train Drivers during failure intervention.

Each LRV has four motorized bogies with two traction motors each, controlled by

choppers with IGBT thyristors that activates the traction system. Traction and

braking can be controlled using the Hand Controller located at each Driver’s Cab.

The braking system is composed of Electrical, Mechanical Disc and

G. Power Supply System

There are eight (8) Traction Power Substations (TPSS) along the MRT-3 system

comprising seven TPSS dispatched along the line, strategically installed in selected

stations and one in the Depot, each receiving high voltage supply rating of 34.5KV

AC from MERALCO. Each TPSS has two incoming feeders connected to two

independent power substations of MERALCO to ensure power distribution in the

event of failure of one supply line. The Power Supply Network consists of two

sub-networks:

The “traction” sub-network, dedicated to supply power for the movement

and maintenance of trains. This sub-network consists of 34.5 KV feeder

cables, 3000 KW Rectifier-Transformers (RT) and overhead contact

system with a nominal rating of 750 VDC.

The “lighting & auxiliary power” sub-network, dedicated to supply power

to MRT-3 facilities such as stations, ancillary buildings, Depot

equipment, etc. This sub-network consists of 11 KV feeder cables,

Auxiliary Transformers (AT), 480V/220V AC 60 Hz, low voltage

cabinets and backup power supplies.

All TPSS and Substations are equipped with alarm systems that can be monitored

in the Control Center. In case of failure of one substation an alarm is triggered and

manual switching of supply can be performed in the substation. All TPSS are

linked, capable of supplying power to each adjacent section in case of failure of

one substation. This ensures continuous operation even in the event of power

failures. The seven (7) TPSS along the mainline are located in Kamuning,

Santolan, Ortigas, Guadalupe, Ayala, Magallanes and Taft while the TPSS in the

Depot are provided for the supply of power for mainline and maintenance

requirements.

The power supply network of the MRT-3 is provided with grounding/ earthing

network, including lightning protection system for the OCS and stations.

The power supply system is designed to accommodate 2.5 minutes Headway, 3-

car train operation with provision for upgrading to accommodate 2 minutes

headway using 4-car trains. Additional rectifier-transformer units and associated

equipment can be installed in allocated spaces inside substation rooms to provide

for the MRT 3 Capacity Expansion (CAPEX) Project.

H. Overhead Catenary System (OCS)

A simple auto tensioned catenary system is employed in the MRT-3 mainline

consisting of single contact wire 170mm2 cross-section, solid grooved hard drawn

copper and double messenger wires of 150 mm2 cross-section hard drawn stranded

copper. In addition to the messenger and contact wires along the mainline, double

250mm2 cross-section bare copper parallel feeder wires are installed to provide

continuous supply.

In the depot area, span wire registration is employed and the contact wire is fixed

at each end of the wire. This results in a decrease in tension as the temperature

increases and an increase in tension as the temperature decreases. The catenary

system is sectionalized and is provided with outdoor type manually operated

disconnecting switches, to provide isolation as required for operations and

maintenance.

The OCS is designed for rated speed of 120kph, with supports and assembly

mounted on independent OCS Masts/Poles that are integrated to the mainline

viaduct. The OCS, composed of Feeder, Messenger and Contact Wires is installed

overhead via insulated cantilevers and is supported via counterweights to maintain

uniform height from the top of the rail in each section.

Contact wire height is maintained along the line through droppers that are used as

support and current distributor. The droppers are uniformly installed per section

with corresponding leveling height in order to maintain acceptable wire sag. These

droppers are connected to the messenger wires as conductors to feed current from

the messenger to the contact wires and hold as support to maintain the contact wire

height with acceptable tolerance. Double messenger wires are installed along the

line and are connected to the overhead feeder through feeder jumpers.

Isolation switches are located all along the line to allow current distribution from

designated TPSS. In case of emergency or faults in the TPSS, isolation switches

can be operated to allow looping the OCS or manual disconnection during

maintenance. Each isolation switch is fitted with Contact Wire Section Insulators

to separate the distribution of current from adjacent TPSS.

Under the MRT 3 Capacity Expansion Project, a new catenary network will be

installed at the depot area for the additional tracks of the expanded depot stabling

area. Also, additional catenaries will be installed from the end of North Avenue

station up to the future MMRIT-Common Station for the seamless interconnection

of LRT Line 1 and MRT 3.

I. Back-up Power System

Each substation has independent Uninterruptible Power Supply (UPS) system for

emergency back-up. In case of power interruption, the UPS can supply power to

the Automatic Fare Collection (AFC) System, Signaling and other emergency

facilities for three hours duration.

In addition to the above back-up supply, power generators are also available for

the sump pumps and tunnel smoke extraction equipment to provide for emergency

back-up in cases of fire or flooding.

J. Signaling System

The Signaling system of the MRT-3 is a fixed block system which consists of an

Automatic Train Protection (ATP), Microprocessor-based Interlocking, Control

and Supervisory System and train detection system utilizing audio frequency track

circuits with two aspect colored light signals. The Signaling system corresponds

to a Safety Integrity Level SIL 4 and has been designed for 120 seconds headway.

The main line can operate at a maximum speed of 65 KPH and may operate at a

headway of 3 minutes. However, with the inception of extending the MRT-3 line

in the future, the operational headway would be 120 seconds. There is no Signaling

equipment at the Depot, hence the train’s maximum speed in the depot 15 KPH.

K. Communications System

The MRT-3 Communications System consists of the following subsystems which

forms an independent system wide communication. It is installed to operate under

all environmental conditions and even in the event of multiple power failures for a

period of three hours.

i. Public Address System

The Public Address System is used to convey messages to passengers and

station personnel. It has 12 preset digital pre-recorded safety messages and

4 track tape console for piped-in music, and 16 pieces 150 watts power

amplifiers to obtain maximum loudness. All stations are equipped with an

independent Public Address System Console located at each Signaling

Room.

ii. Closed Circuit Television (CCTV)

All stations are equipped with independent CCTV System, controlled and

monitored at each Station Control Room. Pan-tilt cameras are strategically

located at various locations of the station to monitor passenger flow and

security surveillance within station premises. Surveillance cameras are

installed in various public areas such as the platform, concourse,

footbridges elevators and stairways. In the Depot, cameras are installed at

different locations to view train movements inside the yard or stabling area

and inside the tunnel to and from the access track to the mainline. Control

and monitoring of these cameras can be performed at the Yard Master

Room.

iii. Private Automatic Branch Exchange

The MRT-3 system has a centralized telephone system that interconnects

internal and outside calls with the aid of an auto attendant computer. It

maximizes the available 20 trunk lines for the 32 digital and 150 analog

local lines serving the whole stretch of the MRT-3 system, utilizing the 150-

pair main communications cable laid along the MRT-3 carriageway and

linked with the 14 Main Distribution Frames.

iv. Trunk Radio System

The MRT-3 system utilizes a trunk radio system to facilitate

communications between the Control Center, Train Drivers and stations.

Three communication channels are available for operations, namely:

Mainline, Depot and Emergency Channel. The Mainline Channel is

generally utilized for day-to-day operation while the Depot Channel is

provided for maintenance personnel to assist the Control Center and train

drivers during interventions. The Emergency Channel is provided as

dedicated line in case of interruptions and incidents along the line.

L. Automatic Fare Collection (AFC) System

The AFC system of MRT 3 utilizes Contactless Fare Media cards for entering and

exiting the station. This supports both the Single Journey Tickets (SJT) and Stored

Value Cards (SVC). The AFC equipment at the station is composed of Automatic

Gates (AG), Point of Sale (POS), and Ticket Vending Machines (TVM). The

Station Computer (SC) monitors and controls all the station equipment (AG, POS,

and TVM). The Central Computer System–Railway Operator (CCS-RO) and

Monitoring Control Work Station (MCW) collects and downloads various data and

parameters from and to the SC.

M. MRT-3 Control Center

The MRT-3 Control Center located at North Avenue station provides overall

supervision and monitoring of system operation. Equipped with train traffic

control equipment, base console radio system and other major telecommunication

equipment, the Control Center provides round-the-clock management of system

operation and maintenance.

The Control Center remote system (MAN 900) accesses and controls train traffic

as well as monitor the location of the trains, status of the Traction Power system

and other emergency alarm panels.

3. SYSTEM OPERATION

The original Line Capacity of the MRT-3 is designed at 23,640 PPHPD providing

maximum of 20 trains, at 3-car configuration, during peak period with minimum

headway of 180sec (3min). Each LRV can seat a total of 74 passengers and

accommodate 320 standing passengers or a total of 1,182 passengers per train. This train

capacity is based on AW3 crush loading of 8 passengers per square meter.

Presently, the MRT-3 operates from 4:30 AM to 11:00 PM with different operating

periods and train dispatch schedule according to a specific train timetable. The current

loop time is approximately one-hour and ten minutes with a minimum headway of 4

minutes or 240 seconds during peak periods. The average dwell time in each station is

approximately 25 seconds and the maximum train speed is 40kph. Peak periods will be

from 6:30 AM to 9:00 AM and 5:00 PM to 7:30 PM.

4. LOT 2 PROJECT DESCRIPTION SUMMARY

In conjunction with MRT3’s procurement of additional 48 LRVs to increase the line

capacity of the rail system and help reduce waiting time of passengers, the Ancillary

Systems shall be upgraded to accommodate the increase in fleet size.

The additional fleet will improve the existing train configuration of three-car trains to

four-car trains operation.

The Ancillary Systems upgrades include the Signaling, Power Supply and OCS, Depot

Stabling, Depot Workshop, North Avenue Turnback and Taft Pocket Track.

The Signaling upgrade covers among others, modifications of the existing signaling

system which include wayside installations, upgrade of Interlocking equipment and

replacement of signal bulb with LED type.

Signaling works include Interface provision for the construction of a new double cross-

over turnout at North Avenue Station; and the conversion of manual point machines at

Cubao and Buendia Stations to central control.

However, the Signaling Upgrade shall not be included in this contract. The upgrade of

the signaling system described above shall be carried out by the Signaling Provider of

the MRT3. This is being mentioned for the information of the Bidders of this Contract.

The Contractor of this Project shall follow the design requirements and specifications of

the Signaling system to make the Power & OCS system, Civil Works and Track Works

fully integrated to the Signaling system.

5. CONCEPTUAL DESIGN

The DOT-MRT3 CAPEX Project Lot 2 is effectively seeking to provide MRT3 with

sufficient installed Traction Power and OCS capability to achieve the maximum through

put of passengers possible for this mode of transport.

The present design can carry when in as new condition 23, 640 passengers per hour per

direction.

The ultimate or conceptual design should be close to 47,280 passengers per hour per

direction based on the presently proposed 4 vehicle trains, operating on a 2-minute

headway. In the future this could possibly be further improved to 60,000 passengers per

hour per direction by using more efficient trains of say132m with 6 - 22m long cars with

say a total of 230 seated and 1,770 standing passengers (8 passengers per square meter)

operating on a 2-minute headway.

To operate trains of this size and frequency it is reasonable to assume the presently

installed Traction Power facilities require to be doubled, and the OCS requirement in

terms of Voltage drop due to circuit resistance decreased by at least 30% to cover for the

increased line currents due to the larger trains.

The presently installed Traction Power capacity is 30MVA, consisting of 10-3MVA

Transformer-Rectifier sets distributed relatively uniformly along the track way. The

addition therefore of a further 10-3MVA units should provide ample capacity for the

ultimate line requirements.

The increase in Train loads from a present 3 vehicle configuration to a 4 vehicle train

will require effectively an increase in current capacity when accelerating from

4,500Amps to 6,000 amps, just over 30%. To accommodate this with no further

deterioration in volt drop at the pantograph, the present circuit resistance will have to be

reduced by approximately 25%. This can be achieved by increasing the presently

installed copper over-head line cross section estimated at 970sqmm to 1,250sqmm by the

addition of a further 250sqmm feeder cable.

Any further improvements that can be made to the return current path through the running

rails, by cross bonding, upgrading to UIC60 rail and increased cable sizes will further

guarantee the provision of Power to these 4 vehicle trains.

6. PERFORMANCE SPECIFICATIONS

The above concept design is the basis for the performance specification further detailed

here in.

In addition to the chapters on the Power and OCS, the requirements for the Depot

Stabling, Depot Workshop, North Avenue Turnback and Taft Pocket Track are set out.

In particular the RAMS (Reliability, Availability, Maintainability and Safety)

requirements are established, that when achieved will ensure the Lot 2 contract will meet

the expectations of providing the Ancillary services to the DOT-MRT3 CAPEX Project

7. POWER SUPPLY AND OCS

7.1. The Existing Power Distribution and OCS Systems

The MRT3 System receives power at 34.5 kV 60 Hz from the local power utility,

MERALCO, at several feeding points. The Power Distribution Network consists of two sub-

networks:

a. The “traction” sub-network. This is dedicated to the power supply for the movement

and maintenance of trains. This sub-network consists of 34.5 kV feeder cables,

switchgear, rectifier-transformers (RT) and the overhead catenary system. The OCS

system is fed by positive and negative return cables from the rectifiers at 750 Vdc. The

catenary is sectionalized and switched to provide restored line power in the event of an

outage at any location.

b. The “lighting & auxiliary power” sub-network. This is dedicated to the power supply

for the MRT3 facilities such as stations, ancillary buildings, depot workshops/equipment

and offices. This sub-network consists of 11 kV feeder cables, auxiliary transformers

(AT), 480V/220V AC 60 Hz, low voltage switchgear/distribution equipment and backup

power supplies.

The Traction Substations and equipment are designed such that it is possible to install

additional rectifier-transformer units and associated equipment alongside the existing

facilities.

7.2 Upgrading of the Power Distribution and OCS Systems

The MRT 3 will be upgraded by means of this Capacity Expansion project, target to be

implemented by year 2016. The intention is to run 24 train sets (4-car) with minimum

operational headway not greater than 150 seconds by this date. However in the ultimate, 30

train sets of 4 LRV’s will be operated on a 120 second headway.

Since the present operation utilizes 3-car train sets with 3-minute headway, the existing

Power Distribution and OCS Systems also requires analysis to determine the extent of

upgrading.

In particular, the present OCS system shall be studied to ensure that the volt drop along the

line shall not be such as to reduce the performance of the Trains when operating with 4

LRV’s on at this time a 150 second headway. Additional feeder cables shall be laid alongside

the present cables with connections to the Overhead Contact wire as appropriate.

The Negative Return Current path through the running rails to the substation shall also be

studied to ensure the bonding of the rails will meet the new and larger line currents.

A new catenary network shall be installed in the depot area for the additional tracks (Tracks

9, 11-15) of the expanded Depot Stabling Area. The new tension length for the new double

cross-over turnout at North Avenue Station as well as the track works included therein shall

form part of the contract. Finally the extension works for the stabling sidings at Taft Avenue

shall include for the OCS and track works.

This Contract requires that the Power Distribution and OCS Systems shall be configured to

match the upgraded revenue service.

Prior to Contract Award, the Prospective Bidder must demonstrate that he has a very clear

understanding of the existing Power Supply Equipment and Systems, the existing OCS

Equipment and Systems, the existing Controls/Monitoring Systems and the existing SCADA

System. In this connection, visits to the MRT 3 are mandatory during the tendering period

to ensure that the Prospective Bidder is fully aware of the present “as installed” systems and

the necessity for compatibility and integration with the new equipment and systems.

For this purpose, the drawings under Section VII are provided for the Prospective Bidder’s

information.

As the works under this contract will involve activities on a ‘live’ railway, the Contractor

shall adopt and adhere to the MRT3’s Rules and Procedures at all times.

Under no circumstances, shall the Contractor cause disruption to the revenue service. All

staging works, timing and method statements shall be approved by the Owner and the

Engineer before any night or day work is permitted to commence.

The contractor shall follow the design requirement and specification of the Signaling

system to make the Power & OCS system, Civil Works and Track Works fully

integrated to the Signaling system.

15.3.2. Background

Few months prior to the opening of MRT 3 line (Buendia to Taft station) to the public

on July 2000, the Pocket Track which is linked to the Northbound track of Taft

Avenue was discovered to have insufficient length to accommodate the safe operation

of a 4-car train passing from South side of the Pocket Track. Series of meetings and

discussions have been held between the Contractors, Engineers and Owner to resolve

the issue and finally decided to optimize the pocket track by allowing passage of 3-car

train only. Consequently, the ATP balises were relocated to effectively protect the

train’s operation even considering the worst case scenario of trespassing down the

pocket signal in restricted aspect.

Optimization of pocket track was done through the relocation of balises which

consummates the braking distance of the train. The braking distance calculation was

based on the following data:

Vehicle condition - Empty

Brake Deceleration - 2.09 m/s²

ATP antenna to vehicle face distance - 2.8 m

1st wheel to vehicle face distance - 3m

Gradient - 0.146 %

Over-run speed passing the red signal - 19 KPH

After the relocation of balises, the testing was subsequently undertaken. The 3-car

train operation successfully passed the test. The Contractor henceforth issued a safety

certification that the pocket track is passable to 3-car trains and guaranteed that the

installed ATP was functioning normally whatever the situation or scenario.

The test for the 4-car train operation was also conducted in the pocket track and the

result showed that the fouling point clearance requirement was not able to satisfy the

safety criteria.

15.3.3. Recommendation

In order to meet the requirement for the complete operation of 4-car train

configuration in the pocket track, the only option is to extend the track at the northern

side (going to the direction of Magallanes station), which will include the following

major activities:

a) Re-design / removal / replacement of wall structure.

b) Re-design / removal / replacement of tracks including ballast and installation

of additional rails and accessories.

c) Re-design / removal / replacement of Overhead Catenary Section (OCS)

including posts and installation of additional OCS and post.

d) Re-design / removal / relocation / replacement of Signaling equipment

including hardware/software.

15.3.4. Pocket Track Data

The data presented herein are actual parameters gathered at site which may serve to

aid the Contractor in the conceptual redesign of the pocket track. However, it is the

Contractor’s obligation to confirm the accurate data through site survey before using

them as parameters in the detailed engineering design.

Location of Pocket Track Northbound Track, approx. 300

meters from Taft Avenue

Station

Distance Between Signals 138 m

Straight Track 130 m

3-car Train Length 97 m

IRJ to IRJ Distance 133.8 m

4-car Train Length 127 m

Length Between ATP Antennas (4-car) 121.4 m

Track Circuit TX and RX Distance 1m

from IRJ

15.3.5. Pocket Track Operation

The pocket track is a temporary stabling area for reserve train or even defective train.

Trains can enter in the south side and exit on the north side through route setting.

Train may also exit from the south side going to Taft Avenue station through manual

route setting. Nevertheless, the automaton cannot be used in the pocket track

operation.

A new double cross over turnout utilizing track slab methodology shall be constructed

at the north-end side of the North Avenue Station.

Please refer to Section VII Drawings A.5.1 for the illustration of the said new turnout.

16.4. CIVIL WORKS

16.4.1. General

This applies to the non- ballasted plain line on the structure in the main line and on

the non-ballasted turnouts. The concrete plinth rest on the elevated structure deck and

transmits the train loads to the deck. The integrity of the track structure in retaining

track gauge and security of the rail requires that the plinth do not move on the

concrete deck.

The concrete plinth should not be subjected to extraneous forces from the flexing of

the structure. This is ensured by the plinth being made in discrete lengths and not

being continuous. The lengths of plinths are planned at 4.0 meters for curved track

with 600 mm fastening spacing and 3.55 meters for the 750 mm fastener spacing of

straight track (>600 meter radius).

The design of plain line non-ballasted track structure assumes the following:

continuous welded rail, plinth design with plinth anchors, starter bars and key

concrete surface of the structure, discrete supports (not continuous support),

baseplates anchored to plinth, rail elasticity fastened to baseplate and rail to baseplate

insulated. To ensure the integrity of the track structure, the concrete plinth to the deck

connection needs to be checked for:

a. Lateral shear under lateral holdings

b. Stability against overturning of the plinth

c. Resistance against longitudinal movement of the plinth

The objectives of the non-ballasted track design will be continuous welded rail,

discrete (not continuous) support to enable matching of rail head top and running

faces when changing rails or making repair insertions to worn rail during

maintenance, ability to make alumino-thermic welds during both constructions and

maintenance and ability to accommodate hog, sag and other tolerances to the finished

supporting structure.

The plain line non-ballasted track structure may be different in the case of turnouts.

There will be also local adjustments to the non-ballasted track design for items such

as expansion switches with baseplates. The objectives of non-ballasted track structure

for switch and crossing work will be as for the plain line track with the following

additional points: ability to use the same or eliminate the steelwork components of

switches and crossings, including the baseplates used on ballasted tracks, ability to

attached powered point machines on required side (or either side), ability to make

reliable attachment of stockrails and switches for signaling to ensure closure and

detection of switch toes and ability to accommodate switch machine rodding,

clamplocks etc. as required by the signaling.
