Review of Designs and Supervision of Feeder Roads Rehabilitation — 9 Districts

ISC was appointed by SCADeP, funded by DFID and the World Bank, to review existing designs for the rehabilitation of 52.2 km of feeder roads and prepare bidding documents inclusive of recurrent maintenance for 85.6 km of rehabilitated roads across nine districts: Kambia, Port Loko, Bo, Bonthe, Pujehun, Tonkolili, Moyamba, Bombali, and the Western Area Rural District Council.

ISC conducted a comprehensive desk review of all available technical documents, detailed road condition surveys including materials testing, soil investigations, and hydrological studies, and environmental and social impact screening. The team prepared detailed engineering designs, working drawings, Bills of Quantities, technical specifications, and bidding documents.

Construction supervision included oversight of six new bridges, maintenance of two existing bridges, 117 pipe culverts, and 31 box culverts — all completed in line with Government of Sierra Leone guidelines and donor requirements.
