Project Detail
The government of Ghana introduced performance-based contracting methodologies to improve management and maintenance of the country’s road network and Mariswe was appointed to assist with this process.
The assessment study prioritised 240 km of trunk routes in two packages and 800 km of feeder roads in four packages with the objective of improving regional connectivity and urban access, as well as supporting agricultural development.
In performance-based contracting the design and construction risks are transferred to the contracting entity, which is paid a lump sum to provide and maintain the road to specific standards.
Key aspects of the project were road network prioritisation, concept design and preparation of draft bidding documents.
The road and bridge concept design included climate change and fibre optic cable assessments, geotechnical and other specialised investigations. Environmental, social and gender evaluation were critical to support sustainable development, socio-economic growth and investment in poverty-stricken regions.
