Name of associated firm :
Pacific Consultants International - Italconsult SPA - Progressive Consultants (Pvt.) Ltd
Project Location within Country:
Balochistan, Sindh, NWFP & Punjab Provinces of Pakistan
Start Date:

Project Description
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.
Services
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)
