We pioneered alternative road alignments to achieve 15% savings to the target cost on the £84m, 320km road project in Tanzania; and designed alternative pre-cast and mobile concrete batching to improve productivity and reduce waste.
The project involved the construction of 320km of road through the southern highlands of Tanzania between Songea and Makambako and was funded with £84m from the Overseas Development Aid budget of the UK government.
We were engaged firstly to supervise the earthmoving operation through the phase 1 mountainous section, and then to manage the construction of the bridges, structures and drainage culverts.
We determined alternative road alignments through the mountains and organised the earthmoving production teams; initiated a pre-casting solution to road-side drainage channels in the cuttings; invented mobile concrete batching to save on transportation and materials; and trained local staff to supervise works in remote locations.
We achieved 15% savings to the contract Target Cost with the change in road alignments; improved productivity and reduced waste with concrete pre-casting and mobile batching; and increased operational efficiencies with the deployment of local staff.
