1. WHAT IS TECHNICAL BID EVALUATION (TBE)After the specifications of packages have been issued, the specs will be sent to the vendors. Then,

the vendors will provide proposal in order to be rewarded those packages. The engineering team will

collect all the proposal data and examining them which comply technically with the specifications.

This process called technical bid evaluation. Afterward, commercial bid evaluation will compare the

price of the packages proposed by the vendors.

2. PURPOSE OF TBEi. To list down the main scope of supply, extent of specification compliance, major deviations in

order to get a general idea of the completeness of the pump technical proposals.

ii. The TBE will list the important points of each vendor quote that includes:a. Pumps model number and sizeb. Compliance with process duty requirementsc. Mechanical design limitations (pressure and temperature)d. Mechanical and hydraulic operation parameters (such as absorbed power , head rise toshutoff, capacity rise to run out, percentage of best efficiency point)e. Mechanical design features (such as material of construction, seal type, seal flush type,

bearing and lubrication type)

iii. To provide pump information to determine which of the quotes will be fully evaluated.iv. To compare the quotes against the specified requirements.v. Apple to apple comparison between alternative bids.vi. To ensure that the pumps is provided in compliance with the requisition.

vii. All items in the pump TBE that do not meet requisition requirements or that are not clearlydefined in the vendors quote should be highlighted in technical clarification

questionnaire/meeting.

viii. To accept / reject all exception and deviations.3. TECHNICAL EVALUATION METHODOLOGY

4. TECHNICAL EVALUATION CRITERIAi. To select a proper pump for a particular application it is necessary to utilize the system curve

and the pump performance curve

ii. NPSHA > NPSHR to allow pump operation without cavitations. Margin between pump NPSHRand specified NPSHA shall be 1.0m over the allowable operating range

iii. Pumps shall be selected to have stable Vs capacity curves with continuous rise to shut-off. Thehead rise from rated capacity to shut-off shall be between 10% and 20%.

iv. Pumps shall have a preferred operating region of 70 % to 120 % of best efficiency flow rate ofthe pump as furnished.

v. Rated flow shall be within the region of 80 % to 110 % of best efficiency flow rate of the pumpas furnished.vi. Pump shut off head shall be smaller than piping design pressure.

vii. Motor power shall be selected at end of curve kW.viii. Motors, electrical components and electrical installations shall be suitable for the area

classification (class, group, and division or zone).

ix. Upon completion of the technical evaluation, all the bidders were categorized under any oneof the following technical parity bands (TPB):

y GREEN Technically Acceptabley YELLOW Technically Acceptable with Areas of Minor Concerny RED Technically Not Acceptable

x. The technical evaluation criteria were divided into the two (2) categories: a. General

y Vendors Experience Listy Delivery Period / ncotermy Design Lifey Guarantee / Warrantyy Spare Part Listy Deviation List

b. Technicaly Compliance to Standard Requirements (AP 610, ABS, etc)y Package Limity Operating Conditiony Pump Performancey Weighty Utilitiesy Material of Constructiony Inspection & Test Plan
