The combined practice delivers engineering services across healthcare, higher education, mission-critical facilities, science and technology, aviation, and other sectors. Both predecessor firms are recognized for leadership in research and policy, planning, finance, and project delivery, and have worked with organizations such as FGI, ASHE, and ASHRAE. Its clients are facilities and institutions in those sectors seeking engineered solutions and robust project delivery.
