The NHA will use the evaluation criteria described in this Section of the RFP to determine the highest evaluated Bid. The evaluation process will consist of a four-step approach, i.e., responsiveness, conformity, technical evaluation and financial evaluation.

At the date, time and location specifically announced by the NHA, proposal packages received from the Bidders shall be opened in the manner described in Section A.5 (Chapter 1) above. The NHA shall first determine whether or not the Bidders’ Technical and Financial Proposals are contained in separately sealed envelopes. The NHA shall announce to those persons present at the Proposal Opening (and upon request to a Bidder who submitted a proposal but is not present


or represented at the Proposal Opening), the name and address of each Bidder whose package is opened. Such announcement shall be recorded immediately in the record of the tendering proceedings. In order to objectively evaluate Technical Proposals without being influenced by financial data, Bidders failing to separate Technical and Financial Proposals shall be deemed non-responsive and will be so recorded in the record of the tendering proceedings.

The NHA shall then determine whether or not Bidders have included Bid Bonds in their Technical proposals. The NHA shall announce, to those persons present at the Proposal Opening (and, on any request by a Bidder who submitted a proposal but is not present or represented at the Proposal Opening), the name and address of each Bidder whose Technical proposal is opened. Such announcement shall be recorded immediately in the record of the tendering proceedings. Bidders failing to provide the required Bid Bond and other technical information mentioned in B1-B9 shall be deemed non-responsive and so recorded immediately in the record of the tendering proceedings.

The NHA shall not evaluate either the Technical or the Financial Proposal from any Bidder determined to be non-responsive, as reflected in the record of the tendering proceedings.

The public portion of the Proposal Opening will then be closed.

The NHA shall separately, and privately, evaluate responsive proposals in accordance with the evaluation criteria detailed in this Section D.2 of the RFP.

The NHA shall first evaluate and score each Technical Proposal on a scale up to one hundred (100) points. In the event the NHA has evaluated and assigned a score of less than seventy (70) points to a Technical Proposal, the NHA shall not evaluate the Financial Proposal submitted by that Bidder. Provided the NHA has evaluated and assigned a score of seventy (70) points or more of a Technical Proposal, the NHA shall then individually evaluate and individually score the Financial Proposal submitted by that Bidder on a scale up to one hundred (100) points.

The NHA shall then weigh the scores for Technical and Financial Proposals. The overall weighting for the technical and financial components of each proposal will be the following:

Technical Proposal: Forty Percent (40%) of the Scoring Financial Proposal: Sixty Percent (60%) of the Scoring

D.2 Technical Proposal Evaluation Criteria

The NHA has developed a list of evaluation factors that will be used to evaluate each Technical Proposal based on assessments to determine which factors were of critical importance to the selection of the Bidder. The following is a list of the quantitative factors and their associated maximum Technical Point score which will be used for the technical component evaluation:-


Sr. No. Evaluation Factor Max. Score

1 Experience & Profile 30 2 Methodology 25 3 Operations & maintenance procedures and systems 25 4 Implementation Timetable – Work Program 12

5 Innovation and Modernization Proposed & Technology Transfer 08

Total Score 100

D.3 Financial Proposal Evaluation Criteria

Firms/Companies/JV must provide their feasibility study and the financial proposal of the bidder must consist the following information:

1 Estimated Project Cost and its Work Breakdown Structure (WBS)

2 Financing Structure Plan, Financial Data Forms & Time needed to achieve Financial Close.

7 Project Balance Sheet, Income Statement and Profit & Loss Statement

8 Toll charge computation and traffic computation

Non provision of above details may result the bid to be declared as non-responsive. The criteria for financial evaluation will be based on the following critical factors.

1. Base Toll Rate

2. Annual Toll Escalation

3. NHA Revenue Share;

*The Bid with Reasonable Base Toll Rates, Minimum annual Escalation and Maximum NHA share will be the most favorable Bid D.4 Final Evaluation Results The final results of the evaluation process will be determined by adding together the results of the technical and financial evaluations to determine the final ranking of each proposal.

(a) The NHA may ask Bidders for clarifications or presentation of their proposals in order to assist in the scrutiny, evaluation and comparison of proposals. No change in a matter of substance in the proposal, including changes in price and changes aimed at making an unresponsive Bid responsive, shall be sought, offered or permitted.


When clarification or presentation of proposals requires, the NHA shall maintain a written “Minutes of Clarification” report. Adequate notice will be given to the Bidder prior to conducting the meeting.

(b) It may be necessary for the NHA to reject all proposals: (i) Subject to approval by the Chairman NHA, the NHA may reject all Bids

at any time prior to the award. (ii) Notice of the rejection of all Bids shall be given promptly to all Bidders

CONNECTING ROAD NETWORK FOR NEW BENAZIR BHUTTO INTERNATIONAL AIRPORT (NBBIA) ISLAMABAD THROUGH PUBLIC PRIVATE PARTNERSHIP (PPP) UNDER BOT ARRANGEMENT

Chapter – 2

SCOPE OF WORK


A. PROJECT DESCRIPTION

A.1. Background Pakistan is a country that has an extensive and varied transportation system. In recent years there has been considerable investment in the transportation infrastructure of the country. From the 1990’s on ward, the Pakistan National Highway Authority has been developing a network of modern motorways that connects nearly every major city in Pakistan. Air traffic in Pakistan has also registered an appreciable increase during the last 5 years. This was mainly due to public awareness, time saving sense and need for fast means of communication. Air traffic can prove to be efficient for the users only if there is speedy, efficient, and congestion free network of access roads from important parts of the cities to the airport terminals. Due to increased air traffic volume on the existing Islamabad International Airport, Government of Pakistan has decided to take up early construction of ‘’The New Benazir Bhutto International Airport (NBBIA)” located in the outskirts of Islamabad. Design and construction of the network of access roads connecting the NBBIA with Islamabad and Rawalpindi have been assigned to the NHA. The NHA now intends to construct the road network for connecting NBBIA to existing motorways. The project is to be carried out through Public-Private Partnership (PPP) arrangement on Build-Operate-Transfer (BOT) basis. A.2. Site Location The site for new Airport complex is located at approximately 3Kms west of motorways Zero point interchange. The present access to the airport site is through the local road off shooting from Dhuma-Phattak that is located at km 7 on Tarnol – Fatehjang (N-80) road. The project envisages utilization of the current Motorway Link Road between G.T road Interchange and the Zero Point Interchange. The Link Road will be widened to accommodate additional traffic generated by NBBIA. Total length is about 31km, from which 7.1 km of length is along the existing motorway link road (which is to be widened only) and rest of the network will be constructed new. The location map is attached at (FIG.-I).

1.4 CROSS-SECTIONAL GEOMETRIC DESIGN

General

1.4.1 The existing Highway shall be improved and therefore most of the factors here will require improvement only.

Traffic Lane Widths

1.4.2 Traffic lanes on the main carriageway of Bridge and on approach roads shall have a width of 3.65 metres. However, Roadway width of main Bridge between sidewalls shall be 8.30 metres.

Width of walkway 1.20 m

Height of railing 1.05 m

Pavement Cross-fall and Superelevation

1.4.6 Generally, the pavement cross-fall gradient should be 2.5 percent. This may however be varied within the range of 2 percent to 3 percent, if required

1.4.7 On dual-carriageway approach roads, where horizontal curvature is less than the radius shown in Table 1.3 for a particular design speed, superelevation up to a maximum of 6 percent shall be introduced.

Lateral Clearances

1.4.8 The minimum lateral clearance between any structure, roadside barrier or other street furniture shall be 0.6 metres from the edge of the usable shoulder.

Vertical Clearances

1.4.9 A clear vertical clearance of 5.03 metres must be provided between the carriageway and the soffit of all underpasses and overbridges.


5

1.4.10 Where any roadway passes over Pakistan Railways track, a clear vertical clearance of 6.4 metres shall be provided between the top of rail level and the soffit of the roadway bridge.

1.5 PAVEMENT DESIGN

General

1.5.1 The road pavement shall be designed in accordance with the AASHTO Guide 1993, using site specific data for:

subgrade characteristics, (including bearing capacity, water table level and drainage properties);

construction material characteristics; and

expected traffic volumes during the life of the pavement.

Materials

1.5.2 In general, Asphaltic Concrete pavements shall be used, except in cases of unusually high traffic volumes, or where poor sub-grade conditions exist. In these situations a Portland Cement pavement may be proposed if it can be shown to be more economical over the whole life of the road. Alternatively, ground improvement techniques involving geotextile, chemical of mechanical stabilisation may be used, with the prior approval of the NHA.

1.6 STRUCTURAL DESIGN

General

1.6.1 All structures shall be designed in accordance with AASHTO Standard Specification for Highway Bridges 1992, using local environmental factors to determine seismic, flood water, wind and temperature loads and Government of West Pakistan Highway Department Code of Practice for Highway Bridges 1967 (WPCHB) for vehicle loads.

Vehicle Loading Conditions

1.6.2 Vehicle live loads, as defined in the WPCHB, shall be either:

a) class `AA' military loading consisting of the 70 ton tracked vehicle defined in WPCHB Section 4; or

b) class `A' loading consisting of 55.4 ton truck train defined in WPCHB Articles 1.4 to 1.7.

depending on which produces the maximum stresses. The number and placing of these vehicles, as well as the impact factors, shall be as defined in WPCHB 1967.


6

[ It should be noted that the live loads specified in WPCHB (1967) are reported to be exceeded due to overloading and the use of modern high capacity vehicles. There is a therefore a need to review the above design vehicle loads to more closely reflect current conditions. ]

1.6.3 In addition, a single NHA abnormal wheel load of 9,525 kg, applied over an area of 0.3 metres by 0.6 metres, shall be applied at any location on the deck to produce the most severe load effect in the structural element.

Other Loading Conditions

1.6.4 Other loading conditions that shall be taken account of in design shall include, but not be limited to:

longitudinal forces due to traction or braking;

loads due to vehicle impact on barriers, railings and posts;

wind loads (for a base wind speed of 100 mph [44.7 m/s]);

temperature effects causing movements and stresses in the structure (for a temperature rise of 20 degrees Centigrade or a fall of 20 degrees Centigrade from the assumed temperature at the time of construction);

earth pressure loading;

seismic loads (the appropriate seismic zone shall be determined in accordance with the Government of Pakistan, Ministry of Housing and Works, Building Code of Pakistan 1986);

stresses and movements arising from prestressing, creep, shrinkage and differential shrinkage; and

erection loads imposed on structural members at every stage of construction.

Design Methods

1.6.5 The methods and requirements of AASHTO 1992 should be taken into account in all cases.

1.6.6 The seismic analysis of bridges should include a computer-based eigen value analysis to determine the natural frequency and time period of the substructure. As an alternative, for regular structure types, the method given in AASHTO 1992 may be used to determine these factors.

1.6.7 The design of superstructures shall be based on Finite Element Analysis (FEM), and should include grid analysis for determination of forces in longitudinal and transverse flexural members, and plate analysis for bridge deck slabs. Empirical methods should not be used.

1.6.8 For irregular structures, such as curved or skewed bridges, or where new or unusual types of structural form are employed, a more detailed analysis should be performed to completely capture the behaviour of the structure (e.g. a `three dimensional analysis').


7

1.6.9 Localised stress concentrations should be given due consideration. FEM should be used to determine the magnitude of these stresses, and any special reinforcement requirements included in the design.

3. Maintenance Requirements

3.1 GENERAL

3.1.1 It is an implicit requirement of the Concession that the Concession Company shall maintain the facility in good order throughout the Concession Period. It is also a requirement that the Concession Company shall transfer the facility to the NHA, at the end of the Concession period, in an acceptable and well maintained condition.

3.1.2 The assessment of condition at transfer will be made by an independent engineer in accordance with the requirements of the Concession Agreement. Before issuing the Certificate of Transfer the independent engineer must be satisfied that all elements of the Bridge are of an adequate condition such that, in his professional opinion:

no heavy repairs or structural overlay to the pavement will be required within 5 years from transfer;

no major replacement or rehabilitation of toll collection, lighting or traffic management equipment within 5 years from transfer;

no heavy repairs to structures are required within 10 years from transfer.

3.1.3 The Concession Company will be required to prepare and undertake a Maintenance Programme with the objectives of ensuring that the Bridge can be operated efficiently throughout the Concession Period and satisfies the condition criteria at transfer.

3.1.4 Maintenance of the facility can be broadly divided into two specific areas: day-to-day corrective action to remedy faults due to vehicle damage, vandalism and reported malfunctions; and planned maintenance based on regular inspection, assessment of condition against specified performance thresholds.

3.1.5 For both of these types of maintenance activity, a comprehensive database shall be established by the Concession Company, detailing in date order, all reported faults (whether through planned maintenance inspections or reports from members of the public, police or other government bodies) and the corrective action taken. All such records shall remain available for inspection by the NHA for a period of six years.

3.1.6 To assist the Bidder in preparing his Bid the following sub-sections set out the minimum levels of monitoring and maintenance performance that will be expected of the Concession Company. It should be noted that in setting these minimum standards the NHA does not relieve the Concession Company of its overall obligations as set out in paragraphs 3.1.1 and 3.1.2 above.

3.2 ROAD PAVEMENT

3.2.1 The need for periodic maintenance of the road pavement will be determined by the use of annual condition and usage surveys. The function of these surveys will be to record, in both absolute and relative terms, the road pavement's performance with regard to skid resistance, rideability and structural integrity.

3.2.2 On an annual basis, condition surveys shall be undertaken of the whole road pavement within the Concession Area. These surveys shall be divided into one kilometre sections and shall record:


17

the location, type and magnitude of all cracking in the road pavement (block cracking, alligator cracking, longitudinal and transverse cracking, and edge cracking);

the location, condition and magnitude of all existing sealing compound in the road pavement;

the extent of all potholes and patching, both within the pavement and at the pavement edge;

the structural strength of the road pavement and its sub layers, as indicated by the extent of any depressions, or rutting in the inner and outer wheel tracks of the nearside lane;

the extent of any bleeding, stripping or spreading of the road surface;

the skidding resistance of the wearing surface; and

the riding quality (roughness) of the pavement.

3.2.3 Based on the findings of these surveys, a planned maintenance programme shall be developed and agreed with the NHA for the following year, the objective of such a programme being to take remedial action at the earliest possible time to both reduce the overall need for maintenance and the consequent disruption to traffic.

3.2.4 In determining this maintenance programme, it will be a mandatory requirement that the condition of the road pavement conforms to the following minimum performance standards throughout the period of the Concession:

Extent of Cracking and Joint Sealing

3.2.5 Within any one kilometre section of road, the extent of pavement cracking shall not exceed the limits set out in Table 3.1. In all cases, cracking should either be non-spalling or with minor spalling of less than 6mm.

Table 3.1: Road Pavement, Maximum Acceptable Extent of Cracking

Type of Cracking Maximum Acceptable

LevelsCentre Line Cracking

Wheel Track Cracking

Block Cracking

0.1 metres per sq. metre for less than 25 percent of the section length

Extent of Potholes

3.2.6 Within any one kilometre length of road there shall be no more than five existing or patched potholes with a size greater than 500mm x 500mm x 25mm.


18

Extent of Rutting

3.2.7 The depth of rutting at any particular location shall not exceed 5 (five) millimetres and, additionally, over a one kilometre length of carriageway no more than 250 metres shall be rutted up to a depth of 5 (five) millimetres. These criteria shall apply to the mean depth of rutting computed from measurements taken every 20 feet (6 metres) along the length of the road.

Degree of Skid Resistance

3.2.8 The skidding resistance of the road surface shall exceed the SCRIM levels set out in Table 3.2, or other equivalent standards established through use of alternative testing methods. The provisions of the AASHTO Guideline for Skid Resistant Pavement Design should also be followed.

Slip Roads 0.45

Slip Roads with Curvature less that 100m Radius 0.60

Roundabout or Traffic Signal Approaches 0.55

Within Roundabouts 0.55

Riding Quality

3.2.9 The roughness of the pavement, over any one kilometre length, shall not exceed a value of 2000 millimetres per kilometre, as measured using the `Bump Integrator' technique, or an equivalent alternative standard established through use of alternative testing methods.

3.2.10 In addition to ensuring that the road pavement meets the above stated minimum performance criteria, the Concession Company will also be required to conduct a `rolling routine maintenance programme' to ensure that the road pavement and shoulders are adequately protected from rapid deterioration through the day-to-day actions of traffic and water penetration. This programme shall include, but not be limited to:

making good all potholes and edge failures within seven days of their being identified or reported;

sealing all pavement cracks at the earliest possible opportunity following the annual inspection; and

repairing any existing joint or crack-filling sealant that have ceased to be effective.
