New Construction Drawing on our team's collective expertise, we take on a diverse portfolio of new building and infrastructure projects for high-profile colleges and universities, recreational and cultural institutions, and government agencies. [Learn more](/our-services/new-construction) Historic Preservation Our preservation projects focus on maintaining and restoring the structural integrity and aesthetic value of historically and culturally significant buildings. We adapt these structures to meet modern standards and requirements, while preserving their historical essence as they evolve for the future. [Learn more](/our-services/historic-preservation) Renovations | Additions | Adaptive Reuse We transform some of the nation's most significant existing buildings and structures - carefully evaluating their current condition and confirming their ability to support their intended function while preserving their original historical and structural elements whenever possible. [Learn more](/our-services/renovation) Building Envelope We evaluate façades, roofs, and exterior systems to identify issues like building enclosure system deficiencies, material deterioration, water infiltration, and potential safety concerns as well as the source(s) of these problems. Our building envelope services address performance concerns and ordinance inspection requirements through strategic investigation and design, supporting restoration, preservation, revitalization, and long-term resilience. [Learn more](/our-services/building-envelope) Structural Investigation | Intervention Our thorough evaluations identify issues including cracking, corrosion, water damage, foundation settlement, material deterioration, and structural deformation. By understanding a building's condition, we can create targeted plans for the necessary interventions. When action is required, we address underlying problems with precision, minimizing disruption and focusing on extending the structure's lifespan. [Learn more](/our-services/structural_investigation_intervention) Sustainability As one of the first 25 U.S. firms to sign the SE 2050 Commitment, we aim for net-zero embodied carbon in our structural systems by 2050. We prioritize reuse of historical elements, choose low-carbon materials, and align with standards like LEED and Green Globes to deliver healthier, more resilient environments.
