AIRPORTS & RAILWAYS
WBHO were awarded the contract for the construction of the haul road for the new iron ore mine in Sierra Leone. When works started it was determined that the optimal solution was in fact not a Haul Road and the scope was changed to the construction of a rail line from the mine to the port. The limitation in the allowable gradient on a railway line meant it was not possible to go over the mountains as originally planned. With this change in scope also came a major increase in the volume of bulk earthworks required (> 10 million cubic meters) on the job in a short period under difficult conditions. The extremely wet weather conditions in this part of West Africa brought along a lot of challenges to this contract which were overcome in the successful completion of the project. This meant the operations on the railway line could commence as planned. We were also engaged by AML in the construction of various works within the Pepel Port Infrastructure including roads, rail underpasses, a wagon maintenance warehouse and a concrete tippler structure for discharging the rail cars.
