Provincial Highways in Balochistan, Punjab, Sindh & NWFP needed improvement & rehabilitation. For this purpose ADB provided finance. NHA through Consultants carried out screening of priority Highways (4000 km), feasibility study of screened roads (2800 km) and detailed design of selected Highways (745 km) in Balochistan, Punjab, Sindh & NWFP. These roads are generally 2-lane facilities having 7.30 meters wide asphaltic pavement and treated shoulders on either side.
The Consulting Services were divided into 3 Stages:
1. Reconnaissance/Condition Survey (4000 km):
Undertook visual condition survey of 4000 km provincial highways in all the 4 provinces of Pakistan and prepared road & structure inventory. Based on the condition survey and economic priorities, all 4000 km highways were screened and around 2000 kms. of highways were selected for undertaking detailed feasibility study.
2. Feasibility Study (2800 km)
3. Detailed Design (745 km)
ECIL undertook following tasks for the above work at (2) & (3).
Detailed road pavement condition survey and carried out NDT by using FWD. Pavement evaluation made by computer analysis of FWD data.
Detailed condition survey of bridges carried out NDT using electronic equipment. Structures evaluation made by computer analysis of NDT data.
Engineering survey consisting of traverse survey, topographic survey, and cross section levelling.
Traffic & axle load survey and traffic forecast.
Assessment of loads - pavement interaction and study of its damaging effects on structures and on pavement and suggestion of remedial measure
Preparation of specification for weigh bridges
Road roughness survey and Benkelman beam deflection study
Hydrological investigations & study Soil investigations
Geotechnical & material investigations
Prepared preliminary design & preliminary cost estimates
Prepared economic feasibility which includes the derivation of Benefit Cost Ratio (BCR), Internal Rate of Return (IRR), Net Present Value (NPV) and ratio of project cost for the first year benefits of the project to demonstrate the economic and technical feasibility, including testing the results on HDM model
Feasibility Report, Detailed engineering design of pavement including bridges & structures
