Delivering nearly 50 affordable senior living units required the project team to navigate complex challenges, including unforeseen subsurface conditions such as remnants of a buried historic foundation, an underground storage tank and contaminated soil. Work was carefully resequenced to address these conditions while maintaining progress on critical path activities. The integration of underslab utilities, vapor barriers and radon mitigation infrastructure required precise sequencing and coordination, while the site’s location within a designated floodplain required the team to collaboratively develop a modified first-floor structural and enclosure approach that included integration of flood venting at key ground-level areas.
Organized as a four-story residential building, the project balances durability, efficiency and resident comfort through a Type 5A wood-framed structure designed for long-term performance and cost-effective delivery. Sustainability is integrated at both the building and community scale, guided by high-performance design features such as a green roof and solar panels.
