MASS’s engineering division started out of a necessity to solve complex issues and maximize the impact of our projects. With the core team based in Kigali, Rwanda, it has grown to encompass a comprehensive team that includes structural, geotechnical, civil, MEP, site, and environmental engineering services, including carbon accounting. We integrate disciplines by collaborating with designers early in a project, enabling innovation and streamlining project delivery.

Successful building systems are optimized for both wellness and low operational costs. We prioritize natural systems over mechanical ones and materials that have positive social and environmental impacts throughout the supply chain. At the Rwanda Institute for Conservation Agriculture, we engineered 2 million compressed-earth blocks that were made on site by local craftspeople, leading to the world's first climate positive University while injecting money into the local economy.

Successful building systems are optimized for both wellness and low operational costs.

We are working to implement systemic changes in how buildings are designed and constructed in Africa that will directly impact the health and safety of people in Rwanda and beyond. We helped write the first building codes in Rwanda and to develop systems that model safer building practices. We also conduct materials research to help establish guidelines for factors like seismic stability in locally manufactured building systems such as compressed-earth block.

While the engineering division works primarily on MASS-designed projects in Africa, it also supports several of the firm’s U.S. projects, and is in the process of expanding operations stateside. The team is also working with other architecture firms to provide engineering services in Africa.
