ADB funded Southern Transport Development Project – Engineering Feasibility and Detailed Design

RDC provided a team of road design engineers, geotechnical engineers, traffic engineers, survey specialists, resettlement specialists, sociologists, environmental experts and other support staff to carry out the preliminary and detailed engineering services. This proposed highway aimed at improving the overall efficiency of the road sector as part of a strategy for raising national economic performance. The services provided were on a two component basis as follows.

Preliminary Design Phase: Key elements were to determine appropriate design standards and parameters on the basis of the Feasibility Study considering appropriateness and economy; reach agreement with the Road Development Authority (RDA) and the ADB on the standards and parameters; and establish final alignment based on the approved trace of the feasibility study.

The project also carry out numerous sub-studies to enable detailed designs, such as improve the trace of the alignment by avoiding critical locations, e.g. built up areas, environmentally sensitive areas, and seek favourable alignment features, such as intersections with existing roads, major bridge locations, areas with minimal resettlement or land acquisition requirements. Develop and design new or improved road access from the project road destination points, permitting an appropriate level of service for the expected level of traffic. Update traffic assignment and forecast, determine traffic parameters for pavement and road design. Execute traffic design, including passing lanes, service points, layout and locations of intersections, inter alia. Carried out accurate topographic survey covering a band 100m on each side of the approved design alignment. Evaluation of the land tenure, land ownership patterns, land values, socio-economic and political parameters of relocation and resettlement of affected families through a program of comprehensive environmental impact assessment studies. The project analysed the data generated by these sub studies and recommended optimal solutions.

Detailed Engineering Phase: Based on recommendations of the above phase of the project, and instructions for the execution of geo-technical and hydraulic investigations, this component prepared the detailed design for the Project. Tasks involved additional topographic and other surveys, geotechnical investigations, hydraulic and hydrological studies, finalization of geometric design, road safety audit of the design, updating the EIA and resettlement plan in consultation with the RDA. Work included preparation of detailed specifications for each work item, taking into account relevant standards.

The project services were designated in a two fold manner addressing design review and construction supervision. Phase 1 considered all possibilities of cost reduction of the works by making adjustments to the designs, as technically acceptable within the approved design standards and specifications, and incorporating the designs of the utility agencies in relevant construction drawings. The phase 2 construction supervision component involved checking and evaluating agreed upon contractors’ work plans, maintaining continuous check of the design of bridges carried out by the contractors, and provided necessary technical assistance.

ADB-EU funded Tsunami Affected Areas Rebuilding Project (TAARP)

Implemented through the RDA, this project was formulated to rebuild and rehabilitate Tsunami affected roads and bridges in the South and South East region of Sri Lanka.
