Building Structural Design
Distilling the essential components of every project forms the basis of this structural work. Regardless of size, shape, or materials, the team brings a rigorous analytical approach to the design and detailing of new and complex building structures.
Seismic Retrofits and Historic Renovations, Adaptive Re-use
Balancing the preservation of historic aesthetics with modern safety upgrades, these engineering solutions extend the lifespan of existing structures. The process coordinates evaluations and design to address aging materials and undocumented building systems.
Sustainable Design
Developing and implementing efficient structural systems minimizes material use and waste. The practice champions cutting-edge sustainable materials, such as mass timber, and alternate project delivery methods to limit the environmental impact of construction.
Master Planning and Structural Studies
Collaborating with architects and owners on feasibility studies and campus planning provides the analytical clarity needed to guide decades of future growth for major institutions.
Tenant Improvements
Renovating, improving, or adding onto existing structures houses new occupants while preserving structural stability. The design team handles modifications ranging from minor layout updates to extensive specialty installations.
Construction Engineering
Facilitating the safe and efficient assembly of complex designs, this structural support leverages hands-on experience to assist contractors. Solutions include shoring systems, underpinning, temporary rigging, and crane logistics.
