Radisson Blu, Douala: Re-engineering an 18-story building in Cameroon
An existing 16-story, 20,000 m² residential building was being redeveloped into a 180-key Radisson Blu in Douala, Cameroon. While the architecture and interiors were complete, the MEP systems required significant re-design to optimise cost and operational efficiency.
Key outcomes
Ascentis redesigned all MEP & ELV systems on Revit, fully coordinating with other disciplines in a federated BIM model. This model also allowed the precise quantification of all the retrofit works as well as the production of builders’ works drawings, thereby greatly facilitating the works at site.
A few key value engineering highlights that made the project financially feasible for the developer include:
- Reducing energy intensity by 49%,
- Reducing the cost of all MEP and ELV systems by 38%.
- Optimising the design of the façade (-47%) and the interiors (-32%)
Ascentis provided critical expertise in redesigning the MEP and ELV systems for our Radisson Blu development in Douala. Their technical approach, on BIM, improved energy efficiency and reduced costs while ensuring a seamless coordination with the existing structure. Their value engineering efforts also helped optimize the façade and interiors, thereby reducing construction costs and making the project financially viable. While the project is currently on hold, Ascentis’ work added significant value, and we appreciate their professionalism and attention to detail throughout the process.
