BACK TO PROJECTS
Name of associated firm :
Halcrow Group Limited (Halcrow) Resource & Engineering Management Corporation Pvt. Ltd.
Project Location within Country:
NWFP, Punjab, Sindh & Balochistan.
Start Date:
June 2001
Completion Date:
December 2002
Project Description
NHA has planned to undertake the rehabilitation and maintenance programme of 957 km of priority sections of National Highways mostly N5, N25 and N70. Out of this 629 km required field investigation, outline design & Turnkey Tender Documentation and detailed design of 328 kms including tender documents.
NHA intend to invite Turnkey Tenders from contractors. For this purpose, NHA appointed ECIL to prepare an outline design. Turnkey specifications, engineer's estimate and Turnkey Tender Documents for Rehabilitation of selected sections of National Highway and multi year maintenance contract.
Services
- Collected and verified NHA supplied data in respect of Traffic Surveys and Network level economic evaluation using the HDM model.
Detailed traffic studies were planned on the project road sections to estimate the volume of traffic and the trip-marking pattern. Following traffic surveys were undertaken:
-
Mid block classified Volume counts by vehicle category
-
Origin and destination surveys
-
Journey Time / Speed surveys
-
Axle load studies
On the basis of the above studies and analysis of survey data the traffic estimates for each section of the project road were prepared. The base year traffic estimates were projected to the design year by using appropriate traffic growth rates. The projected traffic was also used to develop the level of service estimates and the Equivalent Standard Axle repetitions during the project design life.
- Carried out condition survey / preliminary structure assessment of existing structures
- Topographic Surveys
- Soil Investigation
- Conducted capacity analysis and road safety audit of each section
- Specified design criteria for detailed design of rehabilitation of pavement, structures and drainage works
- Prepare outline design of road rehabilitation work
- Prepared turnkey tender documents based on FIDIC guidelines
- Detailed design of 328 km of the National Highway Section
