tender being rejected. If a tenderer refuses to remove the tag and the tender is not rejected, it may be

evaluated and an alternative tender adjusted price determined by the Principal. If the consequence of the tag is

unacceptable to the Principal, the tender will be considered to be non-conforming and will be rejected.”

108.2 “Alternative Tenders - Either:

Alternative tenders will not be accepted;

OR:

Tenderers may submit alternative tenders which meet the same objectives as the tender specification, but which may allow the Contract

Works to be provided in a more economic, cost effective or efficient manner. Only alternative tenders which are within the scope of the

request for tenders, and which meet the requirements shall be considered. Tenders varying the duration of the contract shall only be

considered where the request for tenders specified that such variations were acceptable, and advised how they would be evaluated. The

duration of term maintenance contracts may not be varied (see Special Conditions of Contract 2.5).

The tender amount for the alternative tender is to be inserted on the appropriate form of tender provided. The Principal shall not be bound to

accept any alternative tender. The onus shall be on the tenderer to provide sufficient information with the tender to allow the tender to be

evaluated. Failure to provide sufficient information shall be grounds for rejecting the alternative tender. In addition to the items listed above,

alternative tenders shall include at least the following:

(a) A statement identifying the points of difference between the alternative and non-alternative tender.

(b) Materials or method specifications, in cases where it is intended to utilise materials or methods for which no specification has

been given in the tender document.

(c) A statement describing the design essentials, including preliminary drawings and the name and professional qualification of the

designer, in cases where the alternative tender involves an alternative design.

(d) A proposal for dealing with interim payments, in cases where the schedules of quantities given in the tender documents are not

applicable to the alternative tender.

(e) Name of client and location where the alternative has previously been used.”

“109 Tender Evaluation

109.1 Tenders shall conform to and be evaluated in accordance with the current issues of New Zealand

Transport Agency’s Contract Procedures Manual (SM012).

109.2 Tenders will be evaluated by the Lowest Price Conforming Tender method. This tender evaluation

process will be conducted in two stages as follows:

(a) The first stage shall consist of ranking tenders in ascending order based on prices.

(b) The second stage shall consist of determination of tender acceptability when assessed against

each of the non-price attributes defined in the Supporting Information contained within these

documents (Annexure C);

(c) The consultant’s completion report on past contracts.

Determination of acceptability shall commence with the lowest priced tender and shall cease when the

first acceptable tender is determined.

Each attribute shall be scored on a pass/fail basis. Any attribute which scores a fail may exclude that

tender from further consideration for NZ Transport Agency subsidised works. A fail may also exclude

that tenderer being considered further for work unsubsidised by NZ Transport Agency.

109.3 Evaluation of Alternative Tenders (Where Alternative Tenders are Allowed)




Alternative tenders shall be evaluated in two stages as follows, after the evaluation of non-alternative tenders has been

completed:

(a) The first stage shall consist of determining tender acceptability when judged on technical competence and

assessed against the non-price attributes. Each attribute shall be scored on a pass/fail basis. Any attribute which

scores a fail will exclude that tender from further consideration.

(b) The second stage shall consist of assessing the difference in the present value of the end result offered by the

preferred (lowest priced) non-alternative tender and each of the alternative tenders. The alternative tender price

shall then be adjusted by this amount.

(c) Each of the adjusted alternative tender prices shall then be compared with the preferred non-alternative tender

price to determine the best tender. If the preferred non-alternative tender remains the best tender following the

evaluation of alternative tenders then only this tender will be accepted. The Principal shall not be bound to accept

any alternative tender.

109.4 The Principal is not obliged to award a contract in response to this tender.”

The Principal has applied for and received a Resource Consent for the project, a copy of which is attached in the Appendices.




3.0 SPECIFICATIONS

3.0 Specifications Page 1



3.1 GENERAL SPECIFICATION 3.1.1 LOCATION OF CONTRACT

This Contract is to construct a cycle and walkway path from Stanley Road, through the back of Awapuni

School to Waikanae Creek, then across the Creek (bridge construction not in contract) with a link to

Anzac Street and the main route heading through Alfred Cox Park to Grey Street. Refer to the drawings

for a precise location of the works.

3.1.2 SCOPE OF WORK

The scope of Works is as follows. The path will consist of a nominal 3m wide, 100 mm thick reinforced concrete slab (150mm in places) on a bed of granular subbase. The route of the path will meander through the site making the best use of the existing flat terrain and minimising the amount of earthworks involved. The route also includes widened concrete entrances at Stanley Road and Grey Street and intermediate concrete node points. The Contractor shall note that the standard of the finished project is required to be very high and must be undertaken by qualified tradespeople. The path itself must flow smoothly through the site and have no sudden changes of line or level. A very good concrete finish is required, with no ponding of water on the surface or uncontrolled cracking. The adjacent ground cover must be reinstated to as good as original, and the levels/shape must be such that it does not retain water and is readily mowable, level with the edge of the slab. The Contract comprises the supply of plant, labour and materials for the completion of the Works, all necessary reinstatement and clearing of the site on completion to at least the equivalent standard that existed prior to commencing the work, and to the satisfaction of the Engineer. The works include but are not limited to the following: General

• Establish Contractor’s plant and labour on site. • Provide and maintain a construction programme. • Provide and implement a Quality Control Plan. • Provide and implement a Traffic Management Plan to manage traffic (if any) and pedestrian

movements in the vicinity of the worksite. • Site clearance and preparation, including any relocation work. • Setting out Earthworks

• Strip topsoil to stockpile • Excavation to required profile (cut-to-fill) including undercutting of soft areas and install

drainage to control surface water Footpath • Construct concrete cycleway and walkway track • Construct ancillary concrete paths and features Landscaping • Place topsoil • Sow grass areas and maintain Miscellaneous Works




• Drainage

• Railway crossing including fencing and signage Not included in Contract: • Bridge construction • Furniture (seats, bins, lights, bollards) • Tree removal and planting

• Information signage.

3.1.3 OVERVIEW OF WORK

The following is a descriptive ‘walk-through’ of the Site starting at Stanley Road (NB the work is described in more detail in the Technical Specification): Stanley Road to Awapuni School Stanley Road to Awapuni School Stanley Road to Awapuni School Stanley Road to Awapuni School EntranceEntranceEntranceEntrance (refer drawing Sheet 02) There is an existing paving block and concrete slab walkway that currently leads school children from the school pick-up point on Stanley Road to the back entrance of Awapuni School. This path is to be uplifted, the blocks delivered to GDC’s yard at Makaraka and the waste concrete taken off site for recycling. The low level timber barrier is also to be removed to waste (leaving the chained-off access barrier). The new path is to veer away from the boundary fence and skirt around a tree before heading into the school grounds. The line of the original path will be topsoiled and re-grassed. There is a pronounced dip in the ground near the start of the path and this will need to be filled and evened out. There are indications in at least one area that the ground is soft and there may be a drainage problem. Undercutting of weak ground will be necessary, including stabilising and compaction of hardfill. The walkway entrance at Stanley Road is to be widened and will have a feature wall with a grassy bank (refer drawing Sheets 6 and 14). The concrete surface of the entrance area will contain a contrasting concrete pattern effect (decorative concrete band). Bollards will be installed (by others) to prevent vehicle access. The adjacent chained access for maintenance vehicles is to be retained. Awapuni School to New BridgeAwapuni School to New BridgeAwapuni School to New BridgeAwapuni School to New Bridge (refer drawing Sheet 03) As the walkway enters the school grounds it heads towards the main school buildings for a short distance before veering off towards the school carpark. The path then makes its way alongside existing palm trees until it merges with the edge of the carpark. There are a few bollards and a chain that are to be uplifted and relocated. Once past the carpark the path heads towards the creek crossing. The next section runs along the back of what was previously a timber treatment yard and the ground is likely to contain waste timber products and contaminated materials. The intention here is to disturb the ground as little as possible so as not to uncover buried waste. Surface material that is removed in order to found the path on firm ground must be taken to an approved site that will accept such material. Filling will be required to gradually raise the path up to the level of the railway track. An open drain running alongside the railway embankment will require culverting and fallen trees removed. The path narrows to 2m as it crosses the railway line and to match the bridge width. A formal ‘maze’ railway crossing is to be installed either side of the tracks as required by KiwiRail (refer drawing Sheet 07). Although this railway line is used infrequently, THE Contractor shall adhere to any reasonable conditions applicable to working on or alongside railway lines. It is expected that the bridge construction will be proceeding at the same time as the walkway and, due to the likely overlap between the bridge abutment and the far (river) ‘maze’, close cooperation and coordination will be required between contractors. The path in the vicinity of the bridge will contain a timber sleeper feature at both approaches. New New New New Bridge to Anzac StreetBridge to Anzac StreetBridge to Anzac StreetBridge to Anzac Street (refer drawing Sheet 03) The bridge contractor’s work will terminate at the back of the ‘Park’ abutment, and this is where the path will recommence. Once again it will gradually increase in width and will contain the ‘sleeper’ feature. The path will head directly towards an existing park entranceway located between houses on




Anzac Street. Part way along there will be a 3-leg ‘node point’ where the path will also veer off along Alfred Cox Park. This node point will include a central area of strengthened concrete to accommodate an art feature, as well as contrasting concrete bands at each leg. Two legs of this section of the walkway will include a thickened (150mm) concrete path to allow access for maintenance vehicles. This area of the park contains a disused BMX Bike trackway, which is to be removed and the ground levelled. Suitable fill material is to be salvaged for reuse but all other material (tyres, concrete and timber) is to be taken off site, and the area contoured, topsoiled and regrassed. The path up to Anzac Street will be located between existing garden boundary fencing and will terminate at the street footpath. Bollards will be installed at a later date to restrict vehicle access. Note that Alfred Cox Park has been formed from a capped-off city waste disposal site. In order to avoid exposing waste material (which may require removal to an approved disposal facility) it is intended to restrict excavation work to the minimum required to construct the walkway. BMX Track to Grey StreetBMX Track to Grey StreetBMX Track to Grey StreetBMX Track to Grey Street (refer drawing Sheet 04) Much of the Park section of the walkway will meander between existing trees and will follow the contours of the park surface, with cuts and fills to form a smoothly undulating pathway. Care must be taken to ensure that the walkway does not form a dam and restrict the flow of surface water to the creek. One low section in particular will have a culvert installed to direct water under the path. Additional drainage may be necessary depending on the level of the new path and what re-contouring can achieve. The park contains baskets and posts for ‘Frisbee Golf’. Four posts are in the way of the new walkway and they are to be removed and relocated at the direction of GDC and staff working at the nearby Visitor’s Centre. Two ‘nodal points’ are introduced along the path to allow for rest and lookout areas (refer drawing Sheets 04, 09 and 10). The first makes use of a raised area near a sewer pipe that crosses the creek. A concrete platform is to be constructed and will contain seating and bins (by others). The concrete at these nodes will be in contrast to the path concrete, as will short lengths of path at either leg leading to the platform. The second ‘nodal point’ is similar, and both will contain provision for a statue to be installed in the future. Near the Grey Street entrance (refer drawing Sheets 05 and 11) the walkway will replace an existing paver block path (pavers to be transported to a site at Makaraka). It will once again meander between trees and terminate at a concrete platform similar to that at Stanley Road, with contrasting concrete finishes, bollards and seating (by others). There is a significant rise up to the tie-in at the existing footpath and filling will be required to reduce the slope of the path. This contract will be part of a city-wide cycle and walkway network as well as acting as a safe route for school children, and therefore good customer relations and a high standard of workmanship are paramount to the successful completion of the project. In particular the contractor will be expected to: • Adhere to the agreed programme and avoid any public perception that work has stalled for no

apparent reason.

• Keep affected parties informed as to the intended programme of the work and the impact that

the work will have on them, and update as necessary.

• Have in place and be able to demonstrate a system for dealing with public complaints.

• Ensure that the construction site is kept safe 24/7 from human interference and from

inclement conditions.

• Accommodate safe alternative routes for pedestrians (particularly school children) so that

normal access and usage can be maintained.




The above factors will be taken into account when assessing whether or not the contractor has met expectations and the intent of the contract.

3.1.4 STANDARD SPECIFICATIONS AND PUBLICATIONS

This contract shall be carried out in accordance with this specification together with the NZTA, Opus and NZ Standards referred to in the Technical Specification. In addition, the following shall apply:

TNZ TQS2 Transit New Zealand Quality Standard TNZ Q/3 Normal QA Level Contracts TNZ Code of Practice for Temporary Traffic Management The Construction Act 1959 The Construction Regulations 1961 The Building Act 1991 The Health & Safety in Employment Act 1992 The Resource Management Act 1991 It is the Contractor’s responsibility to obtain access to a set of the publications referred to. The Contractor shall be deemed to be familiar with these Standard Specifications and shall be expected to have the specifications on site at all times whenever associated work is being carried out. Copies of TNZ Standard Specifications can be viewed on NZTA’s website: http://www.nzta.govt.nz or at Opus International Consultants Limited, Gisborne Office. NZ Standards are cited throughout the Specification, and they are available for purchase from the Standards Association of New Zealand (SANZ) or can be viewed at Opus International Consultants Limited, Gisborne Office. This Specification (including drawings and attachments) will take precedence over the standard specifications.

3.1.5 HOLD POINTS

Hold Points have been defined at various stages in the construction process to cover specific control points when submission of quality assurance documentation is required and/or the Engineer/Engineer’s Supervisor wishes to have the opportunity to inspect before work proceeds further. Further to Clause 6.4.4 of NZS 3910, the notification of readiness for inspection, recording, measuring and testing shall be a minimum of 24 hours prior to the availability of the work for the inspections etc. The “reasonable time” period shall not be less than 24 hours. Inspections at Hold Points will normally only be carried out between 8 am and 5 pm on Working Days as defined in NZS 3910.

3.1.6 DRAWINGS

The drawings included as part of the Contract Documents are listed in Section 6.0 Drawings. Should ambiguities be apparent between the plans and the specifications the drawings shall take precedence.

3.1.7 PLANS TO BE KEPT ON JOB

At all times a complete set of plans and specifications is to be kept on the job by the Contractor. The Contractor shall ensure that, before any portion of the work commences, the foreman in charge of the works has studied the plans for that portion, and is familiar with the details of work required, the position of any services and the requirements of the specification relating to the work.

3.1.8 CONTRACTOR TO INSPECT SITE

The Contractor shall be deemed to have visited the site of works, and to have made himself familiar with all local conditions, the accuracy of the information provided, and any other matter that may in any way influence construction of the works.

3.1.9 CONSENTS

A Resource Consent has been obtained and is attached in the Appendices. The Contractor must obtain all other consents necessary to complete the works. The Contractor shall comply with the Conditions imposed on all consents obtained. With reference to the Resource Consent there are a number of Conditions associated with the need to work in the vicinity of the park area (previously a City waste disposal site) and at the rear of the ex-timber treatment yard (near the railway crossing). An assessment of both sites has been carried out which indicates the presence of buried hazardous substances, namely asbestos and arsenic. It is extremely unlikely that such substances will be encountered to any significant extent as in




general the new path will be placed on or above the existing surface and therefore contaminants are unlikely to be disturbed. Where we are excavating below ground level (for reasons of substandard subgrade strength) then such material will need to be removed under controlled conditions (employing suitable safety equipment) and disposed of off-site to a waste disposal location that will accept and treat such waste.

3.1.10 PROGRAMME OF WORK

The Contractor shall submit a detailed programme of work (critical path diagram or dated bar chart that clearly identifies the critical path) within five days of the acceptance of tender or before commencing work on site, whichever is sooner. The submitted programme (the baseline programme) shall identify each operation and show how the work will be carried out within the contract period. The programme shall allow for all constraints to the works either detailed or implied in the documents. The programme shall be updated weekly and a copy submitted with the Contractor’s Weekly Report. The updated programme shall clearly show any variances in the baseline programme, and the Weekly Report must detail reasons for any delay to the programme. The Contractor shall programme the work so as to cause a minimum of inconvenience to affected parties. The programme shall be prepared and electronically stored using Microsoft Project so that it can be readily updated. The programme shall be presented to the Engineer as a clearly readable hard copy in format suited to sheets no larger than A3 size. Due to the restricted width available and the impact of school children using the existing path, the Contractor shall allow in his Programme to complete the section of walkway from Stanley Road to the school entrance during the school holiday period (30 September to 11 October), and this is likely to require that this section be the first to be constructed. The Contractor shall also note that the school property will be used for camping of visitors attending the Rhythm & Vines festival, which will commence on 27 December. The Contractor shall allow for the grounds to be used for this purpose on the lead up to the festival.

3.1.11 WEEKLY REPORTS

In order to provide a record of progress and to keep the Principal up to date it is a requirement of this Contract that the Contractor submit weekly emailed reports to the Engineer summarising progress on site. The reports are required to be submitted by 4:00pm each Friday. The reports shall contain comment on the following: • Comparison of actual progress with the current Programme of Work, including reasons for

delays

• Provide information where Variations or time extension claims are being considered,

• A summary of all works completed during the preceding week, giving the location, extent and

type of work.

• A summary of any quality control testing carried out during the preceding week.

Each weekly report shall be submitted regularly once work has commenced on site. The reports are to be submitted regardless of whether any work has been completed or not.

3.1.12 SITE ESTABLISHMENT AND ACCESS

Access to the southern portion of the Site (south of the Creek) will be via the path entrance at Stanley Road or from within the school grounds (by agreement with school authorities). The northern (Park) portion of the site will be accessed from the Grey Street entrance and from the chained entry points off Anzac Street (key available from GDC). In the case of both the public park and the school grounds the




Contractor must restrict his working area to a minimum so as not to unduly interfere with the proper use of both sites. As stated previously, Alfred Cox Park has been formed on a Council refuse disposal site and the Contractor must take suitable precautions if waste material is exposed. Likewise the area between the railway and the nearby timber yard may contain timber preservative materials and disturbance shall be kept to a minimum.

The Contractor shall keep the Site safe and tidy at all times, and shall avoid the spread of waste material through the park, school and creek areas. Site establishment includes all work involved in the establishment of the Contractor on site, including the provision, maintenance and removal of all temporary works, tidying up on completion, traffic management, and services and general costs (including the provision of as-builts) which are not directly chargeable to other schedule items.

3.1.13 SITE CLEARING AND TIDYING ON COMPLETION

The Contractor shall be responsible for the removal from site of all extraneous materials. Should any accumulation of materials be considered a hazard to the public in general, the Engineer will direct the Contractor in writing to remove such surplus. Should the Contractor fail to comply with the Engineer’s order, the Engineer will arrange for the work to be done and the charges incurred will be deducted from the contract payments. Access to the site with plant will inevitably result in damage to the grassed surface. In order to minimise the need for unnecessary reinstatement at the end of the Contract, the contractor shall keep such access points and tracks to a minimum. At the conclusion of the works the Contractor must restore any damage caused and tidy up, leaving the site of the works in a condition no worse than that existing prior to construction.

3.1.14 CONTRACT QUALITY MANAGER

The Contractor shall nominate a Contracts Quality Manager, who is responsible for the day to day audit of the work and management of the Quality Plan. The Contracts Quality Manager shall carry out inspections of all the work, acknowledge all Hold Points and provide the Engineer with a copy of his inspection checklists with each Weekly Report. The inspection checklists should be sufficiently detailed to include the tolerances and the minimum quality standard required.

3.1.15 CONTRACTOR’S REPRESENTATIVE

Further to Clause 5.2 of NZS 3910, to be acceptable to the Engineer any representative shall have demonstrable experience and competence in the control and site management of the type and scale of works to be carried out under the Contract, including traffic management.

3.1.16 EXISTING SERVICES

A request has been made to service providers to identify existing services within the Site, and these have been annotated on the drawings. Before starting work on Site the Contractor shall liaise with all relevant service providers to update this information and to identify the presence of cables and the like within the Site. Thereafter the Contractor shall allow to work around these services. Should any such services require to be relocated then the Engineer must be advised.

3.1.17 ACCESSIBILITY OF CONTRACTOR




The Contractor’s Representative shall be available on call 24 hours per day to the Engineer. In the event the Contractor’s Representative is unavailable then the Engineer shall be informed and given information to enable similar communication to be maintained with an alternative representative. The Contractor shall ensure that these lines of communication remain open at all times including after hours. The Contractor shall ensure at all times while any work is in progress that a site agent is nominated to be responsible for operations. This site agent shall make himself known to the Engineer in the event that it is necessary for the Engineer to direct operations in the field. The site agent shall ensure that all instructions given by the Engineer are actioned. Such site instruction will generally only be given in relation to matters affecting safety or the protection of assets. Instructions issued to site agents will always be confirmed to the Contractor’s Representative at the earliest convenient time.

3.1.18 ACCESS BY OTHERS

The Contractor shall provide access and reasonable facility to any other individual or organisation duly authorised by the Engineer to work in the general area to which this contract applies. It is anticipated that a parallel contract will be awarded for the construction of a pedestrian footbridge across Waikanae Creek and both contractors will be expected to cooperate fully in order that the project can be completed with the minimum of disruption and delay.

3.1.19 HEALTH AND SAFETY

3.1.19.1 Safety

All work undertaken by the Contractor or his agents under this contract must comply with the Health and Safety in Employment Act 1992. Before any work is commenced on the site and within two weeks of acceptance of tender, the Contractor shall advise the Engineer in writing of the name of ONE person appointed as Safety Supervisor for the work under the Health and Safety in Employment Act 1992. The person shall ensure that all legal requirements and measures for the safety of workers and the public are implemented. This person shall be able to stop or hold work from continuing on any part of the contract, including subcontractors, in the event of any hazards to safety. The Contractor must ensure the site of the works is left in a safe condition after each day’s work. A site-specific Health and Safety Plan shall be prepared for the Contract, the contents of which shall include, but not be limited to: • Contractor’s safety policy • Contractor’s safety training procedures • Site safety management organisation • Site safety personnel and Safety Supervisor • Access restrictions for and induction of visitors to the site • Safety helmet areas • Procedure for identifying and assessing hazards

• Procedure for recording of accidents • Procedure for dealing with emergencies that may arise • Procedure for monitoring health and safety performance • Procedure for monitoring the health of employees where they are exposed to hazards. The Health and Safety Management Plan shall list all known hazards (including those identified below and any others identified by the Contractor) and the measures taken or to be taken to eliminate or




minimise them. It is also to provide for a procedure for identifying and reporting on new hazards by the Contractor’s staff to the Contractor and the Engineer. The known significant hazards on the site include, but are not limited to:

• Vehicular traffic • Construction plant and machinery • Underground and overhead services • Contaminated Land • Noise • Steep, slippery or uneven terrain • Stream or other waterways • Dust • Potential vandalism or break-ins

A copy of the Health and Safety Plan shall be maintained on site at all times, updated as necessary, and made available to the Engineer upon request.

3.1.19.2 Protective Clothing

The Contractor shall ensure that all persons working within the boundaries of the Construction Area,

including the personnel of subcontractors, wear high visibility clothing, safety footwear and any other protective clothing/equipment deemed necessary to carry out the works in a safe manner.

3.1.19.3 Accident Reporting

In the event that an accident occurs on an occupied site (i.e. the Contractor was on site at the time of accident), the Contractor shall provide the following: • Notification within 12 hours of the accident site

• Full details of the event

• A description of the traffic management operating (Stop/Go, 50 km/h, etc)

• Confirming that the site complied in all aspects with any TMP and Health and Safety Plan

• A Contractor assessment of whether there is a possibility that traffic control or worksite

conditions deficiencies may have contributed to the accident.

In the event that an accident occurs at an unoccupied site (i.e. traffic control in place but Contractor not present at the time of the accident), the Contractor shall provide the following: • Notification within five days for any accident that the Contractor becomes aware of

• Confirmation of the status of:

(a) Safety signage

(b) Site conditions at the time

(c) General details of the accident.

3.1.19.4 Working Within a Hazardous Site

The Contractor’s attention is directed to Clause 3.1.8 above which advises that there are potentially hazardous substances below surface level (left over from an old timber treatment site and a capped-off City waste disposal site) and that suitable precautions shall be taken when working in these areas. In particular:

• Wear suitable PPE when working with hazardous material

• Cordon off the site when such materials are exposed or being excavated

• Carte the materials off site using appropriate safety precautions and transport to a disposal site certified to take such material.




3.1.20 PROTECTION OF PUBLIC AND PRIVATE PROPERTY AND SERVICES

The Contractor's attention is particularly drawn to the necessity of adopting measures to protect from damage, trees, fences, hedges, walls, paths, sealed surfaces, entrances, and other service installations, whether in reserves or on adjacent private property. Damage caused by the Contractor’s operations shall be remedied at the Contractor’s expense. The Contractor shall not operate plant with steel tracks on any sealed or concrete surface, except where tyres or planks are provided to protect the surface. The Contractor shall be responsible for the cost of making good any damage to existing services in the execution of the work.

3.1.21 WORKMANSHIP

This is a high-profile contract and therefore a first-class standard of finish is expected through each phase of the work. All construction and maintenance shall be carried out by workers experienced in such work and shall be completed in a workmanlike manner. Any work not specified in detail but necessary for the completion of the Contract in accordance with the letter and spirit of the Specification shall be carried out by the Contractor as if it had been so included.

3.1.22 DUST CONTROL, NOISE CONTROL AND HOURS OF WORK

The Site is within a park area and which has residential property nearby, and is also within school grounds. As such the Contractor shall minimise as much as possible the risk of nuisance being caused by his construction activities. In particular the Contractor shall ensure that dust generated through the construction area is controlled to an acceptable level so there is no dust nuisance that could cause harm to the general public or to workmen. The Contractor will be liable for any claims for compensation, damages or otherwise as a result of dust generated through negligence or ineffective control.

The Contractor shall ensure that all plant items have suitable noise suppressant devices fitted and working. Noise limits applying to the area in which the work is to be carried out are: Average maximum noise level (L10) – Mon-Sat (incl.) Sun & Public Holidays At all times 90 75 Where possible the Contractor shall programme and undertake the noisiest work during normal daylight hours when the ambient background noise is high. Noisy equipment shall not be operated between the hours of 7.00 p.m. to 8.00 a.m. except with the written approval of the Engineer. No work shall be permitted on Sundays except with the written approval of the Engineer.

3.1.23 TRAFFIC MANAGEMENT

The management of traffic shall include the safe control of pedestrians and cyclists through the Site and at the entry points at Grey Street, Stanley Road and Anzac Street. The Traffic management shall conform to the Transit New Zealand Code of Practice for Temporary Traffic Management. Access to the Site may be obtained from either of Grey Street, Anzac Street and Stanley Road. A Traffic Management Plan will be required to be produced to cover activities where frequent access to/from the site is expected at these particular locations.




The Traffic Management Plan shall demonstrate that:

• Adequate procedures are in place to ensure that traffic control is pre-planned

• Specific procedures will be worked through when selecting a suitable speed restriction should a reduction be required.

• Traffic control will be continually monitored and amended where appropriate,

• Decisions are made by people capable of ensuring that all scenarios are considered and properly analysed

• Sufficient recording systems are in place to ensure there is a clear audit trail of what decisions were made for situations encountered.

The Traffic Management Plan shall detail the equipment to be used and include the names (including training) of the nominated Site Traffic Management Supervisor (STMS), Traffic Controller (TC) and Contract Supervisor. No existing permanent sign is to be covered without the prior approval of the Engineer. Restrictions on parking may be necessary in the existing street carparks. Any such restrictions shall only be imposed with the written approval of the Engineer. Entrance into adjacent businesses and residential properties shall not be hindered. The site has to be shared with pedestrians and cyclists, and reasonable measures must be put in place to allow safe passage past the works – your TMP shall demonstrate how you will manage this.

3.1.24 QUALITY MANAGEMENT

3.1.24.1 General

The Principal regards quality as an integral part of the contract works and has assessed the minimum quality requirements to be in accordance with TQS2 (1995). Any quality assurance system adopted by the Contractor shall be used only as an aid to achieving compliance with the Contract and to document such compliance. The Contractor’s quality assurance requirements shall not affect in any way the Contractor’s other obligations under the Contract. Knowledge of, or involvement in, the Contractor’s quality assurance system or the provision of any apparent approval resulting therefrom by the Engineer shall not in itself release the Contractor from any requirements of the Contract.

3.1.24.2 Quality Plan

The Contractor is required to prepare and operate a Quality Plan specific to this Contract. The plan as a minimum shall meet the requirements of TQS2. Throughout the Contract the Contractor shall: • review and where required amend the Quality Plan, • complete the Contract Works in accordance with the Quality Plan, • co-operate with the Engineer to audit the Contractor’s records. The Contractor shall submit his quality plan for acceptance by the Engineer within 5 days of acceptance of tender. On receipt of the Quality Plan, the Engineer shall make immediate and formal acknowledgement of its receipt to the Contractor, and in the next three working days the Engineer will advise acceptance of the




Quality Plan or advise of indicative amendments that are required. The Quality Plan is to be revised and resubmitted for formal acceptance. Work shall not commence until this acceptance procedure is complete. In the period following receipt of the agreed Quality Plan, the Engineer and the Contractor will review that Plan and monitor that the contract requirements are continuing to be met. The Engineer will have the right to make comment or require amendments to the Quality Plan at any time.

3.1.24.3 Quality Plan Requirements

The Contractor shall produce a contract specific Quality Plan demonstrating how the Contractor will meet the requirements of this contract and the requirements of the Contractor’s own quality systems. The Quality Plan shall: • Define the test methods, standards and frequency of testing. • Define responsibilities and roles of the Contractor’s personnel. • Show procedures for reporting test results to the Engineer. • List the proposed Subcontractors and Suppliers. • Show how the works will be checked and how non-conformances will be dealt with. • Define the frequency of formal internal quality audits. • Include a H&S Management Plan.

3.1.25 JOB INSPECTIONS

3.1.25.1 During Works

The inspection of any work by the Engineer or the Engineer’s Representatives will be undertaken between 8.00 am and 5.00 pm on Working Days as defined in NZS 3910, unless otherwise agreed by the Engineer. The Contractor shall give the Engineer’s Representatives 24 hours advance written notice of work required to be inspected. The notice should outline the elements to be inspected and the date and time that the work will be available for inspection. Should any work not be ready to be inspected or supervised within one hour of the time nominated in the notice, or agreed by the Contractor and the Engineer, then a deduction shall be made by the Principal for costs and disbursements resulting from any delay beyond one hour, or for any revisits to the site as a consequence of the delay or rework. For the purposes of assessing costs, time will be measured to the nearest quarter hour.

3.1.25.2 On Completion or During Period of Defects Liability

After being advised by the Contractor that all items for attention under Clauses 10.4 and 11.2 of the General Conditions of Contract have been satisfactorily completed, the Engineer will carry out his inspection of the works. If, after the inspection, items are still not properly completed, the Engineer will so advise the Contractor and will later make further inspection(s) as required to accept all the work. A deduction shall be made by the Principal for costs and disbursements incurred by the Engineer in the second and subsequent inspections.

3.1.25.3 Reimbursements

Such reimbursements as outlined above may be deducted by the Engineer from any money that is due or becoming due to the Contractor. The costs of the Engineer, the Engineer’s Representative or any assistant shall be based on the following rates:




• Engineer to Contract $150/hour • Other Professional personnel $110/hour • Vehicle running $0.80/km (All costs exclusive of GST)

3.1.27.2 Final Claim

The Contractor’s Final Claim shall be submitted in accordance with Clause 12.4.1 of NZS 3910 and shall be in the format of the Schedule of Prices listing all Variations (Unscheduled Items) to the Contract.

3.1.28 AS-BUILT INFORMATION

The Contractor shall provide as–built information on the construction drawings. The drawings shall be neatly marked-up in red-ink where actual construction is different from that shown on the drawings. An A3 size copy of the construction drawings will be provided for the purposes of recording as-built information. As-built information must be recorded by the Contractor as the work progresses and kept on site for inspection by the Engineer’s Representative at any time. The as-built information shall be provided before the issuing of the Certificate of Practical Completion.

3.1.29 PRACTICAL COMPLETION/DEFECTS LIABILITY CERTIFICATE

3.1.29.1 Completion of the Contract Works




Further to Clause 10.4 of NZS 3910 the Contractor shall within 5 working days of the completion of the Contract Works: • Advise the Engineer in writing that the works associated with the Contract Works are complete

and comply in all respects with the requirements of the Contract Documents, and • Request the issue of the Certificate of Practical Completion for the Contract Works.

3.1.29.2 Period of Defects Liability

Works comply in all respects with the requirements of the Contract Documents, and • Request the issue of the Defects Liability Certificate.

3.1.30 STATEMENTS TO THE MEDIA

The Contractor shall not make statements to news media regarding policy, local conditions or contractual matters. All enquiries from the media are to be directed to the Engineer or to the Principal.

3.1.31 ARCHAEOLOGICAL DISCOVERIES

There is the potential for archaeological sites to be present in the area in which the works are being carried out. Work in certain areas may be subject to special observation by representatives of interested parties. The Contractor shall allow in his programme for delays of up to one week in the event of a halt to work while investigations are carried out should artefacts be uncovered.

3.1.32 WORKING ALONGSIDE RAILWAY

A portion of the site is adjacent to (and even over) the existing live railway tracks. The use of these tracks is extremely rare but requires that Contractors abide by the conditions applicable to working in the vicinity of railway property.

3.1.33 MATERIALS AND FURNITURE

All materials shall comply in full with the relevant New Zealand Standards (NZS) (or British Standards (BS) where appropriate NZS do not exist) or NZ Transport Agency’s Standards. Reference to any Standard shall include any amendments or substitutions. Where an item is mentioned by a trade name of other specific reference, it shall be deemed to mean the type of item so mentioned, or any other approved equivalent in quality, finish, durability and serviceability for the purpose intended. The quoting of a trade name shall not be construed as any desire to restrict the use of competitors’ materials, and the Contractor is at liberty of offer, for the Engineer’s approval, any materials he considers equivalent. No warranty is expressed or implied that materials specified are regularly stocked by merchants.

3.1.34 PUBLIC NOTIFICATION

The Contractor shall notify, in writing, at least two days prior to work commencing, all adjoining property owners of the following details:

• Contractor’s Company name

• Description of work

• Date of work commencement

• Duration of work

3.2 TECHNICAL SPECIFICATION

In general the following clause numbers match the item numbers in the Schedule of Prices.

3.2.1 GENERAL ITEMS 3.2.1.1 Establish, disestablish and clean up on completion

Refer Clause 3.1.12 & 13 of the Specification. 3.2.1.2 Survey and setting out

The Contractor shall set out the Works using the information (dimensions and co-ordinates) supplied on the drawings. A list of co-ordinates has been supplied for the setting out of the path. The Contractor shall peg out enough points to provide an indication of the path location and flow, and to allow the Engineer to confirm or make adjustments to the path alignment (this is a Hold Pointthis is a Hold Pointthis is a Hold Pointthis is a Hold Point). The Contractor shall programme reasonable time to have the proposed work inspected. At this time an initial assessment will be made of the cut/fill areas and the impact on surface drainage paths. The Contractor shall ensure that the track gradient and crossfall is as constant as possible. The new track shall not form a ‘stopbank’ preventing natural discharge of surface water – this is to be addressed by judicious filling and topsoiling.

3.2.1.3 Prepare and implement temporary traffic management

Refer Clause 3.1.23 of the Specification.

3.2.1.4 Relocation of services (Provisional Sum)

Refer Clause 3.1.16 of the Specification. Should any relocation of services be required then this will be treated as a Variation for which a Provisional Sum has been included in the Contract.

3.2.2 QUALITY ASSURANCE TESTING & CHECKING 3.2.2.1 Prepare and implement quality plan

Refer Clause 3.1.24 of the Specification.

3.2.2.2 Provide quality assurance testing Refer Clause 3.1.24 of the Specification.

3.2.3 SITE CLEARANCE & EARTHWORKS

This section covers site clearing and general earthworks including stripping of topsoil to stockpile, excavation to footpath depth, and preparation of the subgrade surface. All earthworks shall comply with TNZ F/1 unless stated otherwise. The control of surface drainage shall be undertaken early in the work so as to maintain the natural water drainage facilities and limit the introduction of water into the earthworks. Additional temporary surface drainage works shall be carried out during construction as required to safeguard the integrity of the works. The earthworks shall be carried out in such a manner that their surfaces have, at all times, a sufficient fall to shed water and prevent ponding. The Contractor shall maintain the fill area so that the time required between wet periods and the resumption of earthworks is kept to a minimum. Adequate provision shall also be made for the control of water borne soils.

3.2.3.1 Relocate concrete pavers, bollards, baskets, etc




The Contractor shall uplift the existing concrete pavers located at the start of the path along from

Stanley Road and Grey Street. The pavers are to be neatly loaded on to pallets, wrapped and

transported to GDC’s storage yard at Makaraka.

The bollard/chain barrier adjacent to the Awapuni School carpark is in conflict with the proposed path

alignment. The barrier is to be relocated adjacent to the new walkway and at the direction of school

staff.

The picnic table at the Stanley Road entrance shall be delivered to the school – liaise with school staff

for delivery.

The Alfred Cox Park contains facilities for playing Frisbee Golf, including baskets, posts and marker

slabs. The Contractor shall relocate (to an agreed location nearby) any such features that conflict with

the new path. Allow to liaise with staff at the nearby Visitors Centre.

3.2.3.2 Remove from site surplus materials

The Contractor shall remove from site all surplus materials including:

- The concrete picnic table base at Stanley Road

- The portion of the timber barrier running adjacent to the footpaths on Stanley Road and Grey Street

that conflict with the new ‘Gateways’

- Tyres, concrete and timber materials found in the abandoned BMX practice track. Material suitable

for use as fill is to be stockpiled separately for use elsewhere and the site levelled. The site shall

be topsoiled/grassed in accordance with Cl 4.8 below.

3.2.3.3 Excavate existing concrete footpath at Stanley Road

The Contractor shall uplift and dispose off-site the existing concrete path that runs along the back of the

industrial property between Stanley Road and the school grounds. The waste concrete is to be

delivered to the Fulton Hogan quarry in Matokitoki Valley Road so that it can be crushed and recycled.

Much of the old path footprint will be reinstated with topsoil; allow to break up the subgrade to promote

drainage and the growth of grass cover.

3.2.3.4 Strip topsoil to stockpile

The areas to be cleared shall be stripped of all topsoil, roots, organic and other unsuitable matter.

Stripping techniques shall be such as to minimise excavation of the material underlying the topsoil

cover. The extent of stripping shall be 500mm outside the edge of the concrete slab. Volumes have

assumed a salvageable depth of 100mm.

All tree roots found above subgrade level during excavation will need to be removed. Where massed

roots, or roots over 30 mm in diameter, are encountered then these shall be brought to the attention of

the Engineer for a decision on removal. Where approved, roots shall be severed 200 mm outside of the

proposed alignment, removed from site and disposed of by the Contractor.

Topsoil shall be stockpiled in locations which facilitate later uplifting for respreading. Stockpile heights

shall not exceed 1m. Stockpiles shall not be placed in locations that may endanger the stability of the

stockpile or supporting ground and should not obstruct the public.

Usable topsoil must be kept separate from subgrade material in order to avoid contamination.

3.2.3.5 Excavate to subgrade

Once the available topsoil has been stripped from the site, excavation or filling will be required to

achieve the path subgrade level. Therefore, in order to form a reasonably level and smoothly graded




pathway, judicious use of excavated material for fill will be required. Filling and contouring either side

of the path will also be required (which will involve salvaging and then replacing topsoil over the

raised/lowered area) in order to provide a walkway that melds into the Site.

Because a survey of the Site has not been undertaken it is difficult to provide precise quantities of cut-

to-fill, therefore the Contractor must make his own assessment of how much material requires to be

shifted. Excavation volumes assume an average depth of 100mm and a width of 200mm outside the

path edge. This item will include for either cut-to-fill or cut-to-stockpile of surplus material. Importation

of fill material is not expected to be necessary.

The Contractor shall limit excavation to that which will achieve the required profile and subsequent

footpath construction or other concrete works. 3.2.3.6 Stockpile to fill

Material cut and stockpiled from the pathway that is surplus to filling requirements, and material

salvaged from the BMX track, shall be spread on site as directed by the Engineer. The areas for

spreading of this material include low lying parts of the park that are likely to pond surface water.

Existing topsoil will need to be salvaged before filling (as per Cl. 3.2.3.4). 3.2.3.7 Undercut unsuitable and replace

Once the design/agreed profile has been achieved the Contractor shall test the subgrade to prove

suitability for footpath construction. Testing shall be by means of Scala Penetrometer or other

approved method to a depth of 0.5m. Frequency of testing shall be at 20 m intervals and results shall

be forwarded to the Engineer before proceeding further (this is a Hold Point).

Subgrade material not achieving a CBR of 2 or better shall be undercut and replaced with suitable fill

material to a depth of 300mm, compacted in 150mm lifts.

In areas where it is necessary to remove identified hazardous material then it shall be disposed of at a

landfill site authorised to take such materials. Appropriate precautions must be taken when excavating

and transporting the material, including suitable PPE. 3.2.3.8 Prepare subgrade

The entire surface of the completed subgrade shall be made smooth, firm and uniform by blading,

grading and rolling, approximating the crossfall required on the final surface.

The surface shall be finished so that all points are within 15 mm from a 3 m straight edge laid at any

point on the surface. 3.2.4 PATH CONSTRUCTION

The work in this section involves the construction of the footpath/cycle track and other concrete

surfaces, including the timber formwork, subbase metal and reinforced concrete path (refer Sheet 14

for details).

3.2.4.1 Supply and place 100mm compacted subbase

Following approval of the alignment and levels a 100 mm layer of subbase metal shall be placed in

preparation for laying the reinforced concrete path. The subbase layer shall extend 200mm outside the

edge of the concrete slab.

The subbase metal shall comply with the Local Subbase Specification (copy appended), and

compaction shall be to 95% of Heavy Compaction in accordance with NZS 4402 Part 4 Section 1.2.




The surface of the subbase layer will need to be blinded off with a layer of sand to help produce an even

surface with minimum voids.

The tolerance on the subbase surface shall meet the requirements of TNZ B/2.

3.2.4.2 Temporary edging

Once the subbase surface has been prepared and compact, edging will be required to be installed to

act as concrete formwork. The edging shall be robust enough not to give when the concrete is poured,

but be sufficiently flexible to produce a smooth flowing line free from kinks or sharp changes in

direction.

The Contractor shall use the edging to check that the correct depths of concrete and the specified

crossfall will be achieved. Measurements are required to be recorded every 10m and results provided

to the Engineer before each concrete pour (this is a Hold Point). The Contractor shall allow for

adjustments of the edging to a satisfactory line and vertical profile.

Once approved, the edging must be protected to ensure that it is not knocked off line.

3.2.4.2.1 Timber edging

Timber for the edging formwork in contact with the poured concrete shall be dressed smooth on the

face and two edges and shall be free from knots, cracks and other deformities. Alternatives to timber

will be considered.

It is important that the edging be sufficiently flexible in order to produce a curved profile when required.

The edging can be formed from notched plywood or some other flexible but robust material.

3.2.4.2.2 Flexible garden edging

The ‘Decorative Concrete Bands’ (Type C) at the Gateway locations are to be formed and poured first

and then the main concrete (TYPE B) poured around it. The shape of the band has tight curves that

may best be formed using temporary flexible garden edging. Alternatives will be considered providing a

clearly defined shape is formed.

Note that the edging will have to accommodate the presence of the mesh steel (which will be

continuous through the entire slab). Ensure that the formwork is sufficiently tight to minimise loss of

concrete during the pour.

3.2.4.3 Construct concrete path (incl. reinforcement)

The Contractor shall construct the reinforced concrete slab for the walkway in accordance with the

details shown on the drawings and the following.

The Contractor shall note that a high standard of finish is required on the exposed surfaces of the slab,

and particular attention shall be given to forming the corners.

Concrete and reinforcing shall be in accordance with Opus Standard T-CES 101 (copy attached), the

relevant standard specifications and the following:

a Concrete shall be Normal grade, complying with NZS 3104:2003 with a minimum compressive

strength of 25 MPa at 28 days when tested in accordance with the various provisions of NZS

3112. Maximum slump shall be 120mm (+/- 40).

b Concrete construction shall comply with the requirements of NZS 3109:1997.

c No water is to be added to the concrete on site unless with the approval of the Engineer.




d All reinforcement other than ties and stirrups shall be deformed unless otherwise detailed.

Reinforcement shall be Grade 300E and shall comply with NZS 3402 and placed in accordance

with CES 101.

e The length of lapped splices (without hooks) shall be 40 bar diameters in length.

f Steel reinforcement, at the time concrete is placed, shall be free from loose flaky rust, mud, oil or

other coatings that will destroy or reduce the bond.

g Reinforcement shall be accurately placed, adequately supported with chairs and secured against

displacement prior to placing the concrete.

h The minimum cover to all main reinforcing steel shall be 50 mm unless otherwise specified.

i Immediately prior to placing the concrete the subbase/sand layer shall be saturated with water.

j The path and slabs shall include transverse contraction joints at a maximum of 3m spacings.

The joints are indicated on the drawings but the Contractor shall choose locations to minimise

the risk of cracking. The joints shall be 55mm deep and must be cut as soon as possible after

the concrete has set and will not rip (no more than 18 hours). The preference is that the joints

be formed when the concrete is still plastic by means of inserting a steel strip (or T-section) and

snipping the reinforcement, then filling the gap with a joint fill to prevent ingress of water. The

methodology for joint forming shall be submitted and approved by the Engineer. Avoid placing

the joint where there is an overlap in the reinforcing layer. k In order to promote proper curing the concrete must have a curing compound applied after its

initial set (applied as per manufacturer’s instructions).. l Concrete treatments shall be as specified below. For each treatment a 1m2 sample of slab shall

be prepared in advance in order that they can be approved for use (this is a Hold Point). It is emphasised that surface cracking of the concrete slab will not be accepted. Should any cracks

appear then the entire slab (between expansion joints) shall be removed and replaced. In such cases

the mesh will have to be cut, compromising the continuity of the RC path. The Contractor shall ensure

that there is no differential settlement of the replaced slab (with the inclusion of dowels or similar

method of support) and that the surface level and the finished colour/texture are consistent. Any such

repairs shall be implemented soon after the defects become apparent and the method of repair shall

be submitted for approval by the Engineer.

3.2.4.3.1 Surface treatment - Type A (main pathway)

The main pathway shall be constructed as specified above. In general the concrete slab shall be

100mm thick, the exception being the sections identified in hatching on drawing Sheet 3 which are to

be thickened to 150mm to accommodate the weight of maintenance vehicles.

The concrete shall incorporate 2.5% black oxide and the surface shall have a ‘broom finish’. The path

shall be poured in sections of 25 lineal metres (max). In order to allow for longitudinal expansion a gap

of 15mm is to be left between sections, filled with polystyrene and 15mm depth of flexible filler (colour

gray) securely bonded to the concrete faces. The reinforcement is not to be continuous over the gap.

3.2.4.3.2 Surface treatment - Type B (Gateways, intersections and Lookouts)

The locations of the Type B treatment areas are as shown on the drawings. Concrete shall be plain with

an exposed aggregate finish and containing 2.5% black oxide.

3.2.4.3.3 Surface treatment - Type C (Decorative bands, Thresholds and Sculpture areas)




Type C surfaces are to be plain concrete including 5% iron oxide with a sealed finish or acid wash finish.

The Decorative Bands are incorporated within the Type B slabs and are to be formed first using a

flexible former such as garden edging (refer Cl.3.2.4.2.2 above). A high standard of finish is required in

the formation of these features.

3.2.4.3.4 Thickened slab at sculpture features

The Sculpture areas are to be strengthened with a thickened slab of reinforced concrete – details are

as shown on the drawings. Locations are to be confirmed before laying out the slab. An expansion gap

is to be included to allow separation between the concrete slabs.

3.2.4.3.5 Thickened slab at crossing points

Sections of path near the BMX track are to be thickened up to 150mm to accommodate access by

maintenance vehicles (refer drawings Sheet 3).

3.2.5 DRAINAGE

This section covers the drainage requirements of the site, including culverts and subsoils.

3.2.5.1 Install culverts

A precast concrete culvert (900mm dia) is to be installed alongside the railway embankment and below

the southern approach to the railway crossing. Installation, bedding and backfill shall be in accordance

with TNZ F/3. The invert shall be consistent with the existing channel profile (line and level to be

confirmed on site before proceeding).

A 600mm diameter culvert is also required to drain a ditch located part-way along the park section.

Again, the line and level shall be confirmed before proceeding with the work. Allow to deepen the drain

upstream and downstream to encourage surrounding surface water to flow into the channel.

3.2.5.2 Construct timber headwall

A timber headwall is to be constructed at the entrance to the 600m diameter culvert in the park. The

headwall is to be made from 50mm x 150mm treated timber and shall be robustly constructed to retain

the backfill and blend in to the park surrounds.

3.2.5.3 Install subsoil drain

In an attempt to intercept water before it crosses the path a subsoil drain is to be installed on the

‘upstream’ side of the path and as shown on the drawings. The drain will only be required at locations

where there may be problems with surface/ground water (primarily along the park section) and

therefore the Contractor shall obtain approval to install before proceeding. The depth to invert will be

approximately 500mm but will vary in order to achieve a fall. The pipe shall discharge at suitable

locations under the path and out into the creek or into the new culvert.

Other areas of the park, for example the section from Stanley Road to the school, may also require the

installation of subsoils to encourage drainage – these will be installed as required.

3.2.6 RAISED PLATFORM AT ‘GATEWAY’ ENTRANCE

A raised sloping bank is to be constructed at the Stanley Street ‘Gateway’ as shown on the drawings

Sheets 6 and 15.

3.2.6.1 Reinforced concrete wall




Construction of the reinforced concrete wall shall be in accordance with Opus Standard T-CES 101

(copy attached). Testing for the wall foundation shall involve Scalas at 5m centres, 500mm depth and

a target of 3 blows/100mm (copy results to Engineer). The wall shall be founded on a 100mm layer of

well-compacted subbase.

The exposed face, top and back surfaces of the wall shall be an F6 finish in accordance with NZS 3114

Specification for concrete surface finishes. A very high standard of finish is required, paying particular

attention to surface evenness and continuity of colour.

Backfilling of the wall shall be in accordance with Cl 3.2.3.5 above, and topsoil/grassing with Cl 3.2.8.

3.2.7 RAILWAY CROSSING

This section covers the ‘Maze’ railway crossing from the “maze’ entrance to the new bridge abutment.

The approach slab shall be a Type B in accordance with Cl 3.2.4.3.2 above.

3.2.7.1 Maze fencing

The fencing that forms a boundary for the Maze at the railway crossing shall be constructed from

proprietary aluminium pool fencing to the height and layout as shown on the drawings. The fencing

shall be robust and be suitable for use in a public place and shall comply with NZS 8500. The proposed

consent shall include calculations showing that no damage will be caused by the loading.

6.3.3 The sequence of dismantling shall be as shown on the drawings, or, if not shown, shall be

as consented to by the Engineer. For continuous slab, girder or arch spans, the falsework

shall not be removed until the required time has elapsed after the placing of the last

concrete in immediately adjacent spans.

9 SURFACE FINISHES

9.1 Basic Finish

Except where a particular standard is shown on the drawings or specified in the attached

Schedule of Project Specific Concrete Requirements, the concrete surface finish on

general construction work shall comply with the requirements of NZS 3114, F3 finish for

formed surfaces and U1 finish for unformed surfaces.

9.2 Precast Concrete Units

9.2.1 For all precast concrete units all surfaces except those against which concrete will be

subsequently placed, shall have a concrete surface finish complying with the requirements

of NZS 3114, F4 finish for formed surfaces and U3 finish for unformed surfaces.

9.2.2 Surfaces of precast units against which concrete will be subsequently placed shall be

prepared as type B construction joints (refer NZS 3109, clause 5.6.3).

9.3 Special Finishes

9.3.1 Where special architecture formed finishes are shown on the drawings, these shall be

produced by casting the concrete against formwork complying with the consent procedure

specified in clause 9.3.3.

9.3.2 The colour and surface finish of the concrete for each type of special finish shall be

uniform throughout the whole job. Metal ties for formwork shall be placed in a regular

pattern as agreed with the Engineer.

9.3.3 Unless ordered otherwise by the Engineer, the Contractor shall construct sample panels of

each special finish shown on the drawings. The panels shall be cast using the

Contractor's proposed formwork, concrete mix and method of placing concrete. The

proposed time and method of stripping and method for any additional finishing shall also

be used. Additional sample panels may be required by the Engineer if the initial formwork

or methods do not produce the required standard of finish. When a finish has been

produced to the Engineer's satisfaction, that sample panel shall be the standard for the

whole of the work requiring that finish.

10 CURING

10.1 Membrane Curing

Only where the nature of the site or the shape of the concrete surface is such that water

curing will be difficult to effectively achieve, will consideration be given to the acceptance

of membrane curing compounds or the covering of the concrete with impermeable

sheeting. Where impermeable sheeting (eg, polythene sheet) is used, it must be

continuously secured in position at its edges.


T-CES 101 (NZ)

October 2009 12

The use of membrane curing shall be subject to the written consent of the Engineer,

following the submission of full details of the method proposed (including details of the

curing compound where applicable) and the area of proposed use.

Should a curing compound fail to weather and strip off concrete surfaces leaving an

acceptable uniform appearance, then any additional work (eg. removal by mechanical

means) required to achieve this will be at the Contractor's expense and will not constitute

any extra to the contract.

10.2 Accelerated Curing

Where an accelerated curing process is to be used, the Contractor shall supply evidence

to the Engineer, for his acceptance, that the plant and process is capable of producing the

desired results. The Engineer’s acceptance shall be obtained prior to the application of

accelerated curing to any concrete elements manufactured for the work.

10.3 Curing Time

For unformed surfaces, curing of the concrete shall commence on completion of finishing

operations as specified in NZS 3109: 1997 clause 7.8.2.

For formed concrete surfaces, curing shall commence immediately on loosening or

removal of forms as specified in NZS 3109: 1997 clause 7.8.3.

Curing shall be continued for the period specified in NZS 3101: 2006 Section 3.

Where an accelerated curing process is used, (clause 7.8.5 of NZS 3109 refers) as soon

as the temperature of the concrete unit has returned to ambient, water curing shall be

applied and maintained for a period of at least three days, unless at the termination of the

accelerated curing process the concrete has achieved the strengths given in the following

table as determined from a statistical analysis of compression tests of a minimum of 3 test

cylinders cured alongside and under the same conditions as the concrete unit.

11 DEFECTS

11.1 General

In the finished work concrete shall be sound dense and homogenous, free of any voids,

foreign matter or other defects except as permitted elsewhere in the contract documents.

11.2 Minor Surface Defects

Abrupt or gradual variations in surface evenness, blowholes, honeycombing and other

physical irregularities, which exceed the limits specified in NZS 3114 for the particular

class of surface finish required in section 10 of this specification, and plastic cracks up to

12mm depth shall not be permitted, unless agreed in writing by the Engineer and repaired

in accordance with clause 12.2.

11.3 Structural Defects

Structural defects as determined by the Engineer, including chipping, spalling,

honeycombing and cracking all deeper than 12mm, shall not be permitted unless agreed

in writing by the Engineer, and may constitute grounds for rejection of that component at

the discretion of the Engineer.

12 REPAIR OF DEFECTS

12.1 General

Where defective concrete is present the Contractor shall not undertake remedial

measures without the knowledge and consent of the Engineer.

All defective areas shall be thoroughly investigated to ascertain the extent to which the

defective work extends.

Surface plastering or cement washing to cover up poor workmanship is not permitted.

The colour and texture of repaired surfaces shall match that of the adjacent concrete.

12.2 Repair to Minor Surface Defects

Projecting defects shall be removed by grinding.

Dry pack mortar (Section 4.6) shall be packed into all formwork tie holes and holes of a

similar magnitude.

Other minor surface defects may be repaired by mortaring applied by ‘bagging in’ to a

method agreed with the Engineer.

Any excess mortar including that on adjacent surfaces shall be cleaned off immediately by

scraping with a steel float and/or by subsequent grinding.


T-CES 101 (NZ)

October 2009 14

12.3 Repair of Structural Defects

Structural defects may be repaired at the discretion of the Engineer, in accordance with a

method submitted by the Contractor that has received prior written acceptance from the

Engineer.

13 TOLERANCES ON DIMENSIONS

13.1 Accuracy of Dimensions

All shown dimensions of the concrete shall be established accurately within the tolerances

given in Table 5.1 of NZS 3109 for precast units, and given in Table 5.2 of NZS 3109 for

cast in situ concrete work, unless detailed otherwise on the drawings or as specified in the

following:

Departure from established alignment: 20mm

Variations from the level or from the grades indicated on the drawings:

(a) Overall 15 mm

(b) In beams, slabs, decks, floors, 10mm but not more than 5 mm variation

horizontal grooves, railings and from a 3 m template or straight edge.

similar:

Variations from the plumb or specified batter in the lines and surfaces of columns, piers,

walls and similar:

In dimensions up to

3 m 10 mm

in 6m 15 mm

in 12 m or more 25 mm

13.2 Standard of tolerance

In addition to the foregoing the standard of tolerance shall be such that attachments,

equipment etc, can be installed accurately in accordance with the drawings and

specifications. It is stressed that the acceptance of tolerances does not absolve the

Contractor from obligations to work within the boundaries of properties and to avoid

encroachment.

13.3 Reinforcing steel and concrete cover

For tolerances on reinforcing steel and concrete cover see Section 3.9 of NZS 3109.

APPENDIX A

CONCRETE DURABILITY REQUIREMENTS

A1. General

This Appendix refers to the following documents in addition to those listed on page 1:

AS 3582.1-1998 Supplementary cementitious materials for use with Portland and

blended cement – fly ash

AS 3582.2-2001 Supplementary cementitious materials for use with Portland and

blended cement – slag – ground granulated iron blast furnace

AS/NZS 3582.3-2002 Supplementary cementitious materials for use with Portland and

blended cement – amorphous silica

AS/NZS 1170.0-2002. Structural Design Actions. General Principles

The durability of concrete structures and elements shall satisfy the requirements of the New

Zealand Building Code Clause B2.

For designs based on the use of concrete made with GP, GB or HE cement complying with NZS

3122 with or without supplementary cementitious materials complying with AS 3582, durability of

the reinforced or prestressed concrete shall be designed in accordance with New Zealand

standard NZS3101:2006 Concrete Structures Standard, Chapter 3, modified as follows:

“Several durability enhancing measures other than those specified in NZS 3101:2006 can

be taken to extend the life of concrete structures and provide the required durability. These

include concrete coatings, corrosion inhibiting admixtures, galvanized or stainless steel

reinforcement, controlled permeability formwork, GRC permanent formwork, and cathodic

protection. Life prediction models offer an alternative approach to use of Tables 3.6 and 3.7

in NZS 3101 for determination of covers and mix designs for the C and B2 zones. Adoption

of any of these or other alternative measures shall be the subject of a Special Study as

described in AS/NZS 1170.0, and shall be fully documented and submitted to the Engineer

for acceptance.”

In the event that the Contractor cannot obtain a copy of NZS 3101:2006, a copy will be made

available on request for viewing at the local office of Opus International Consultants Limited.
