Transforming Visions into Realities

SIGAL has provided preconstruction and construction services for many of the Washington Area’s most challenging construction projects. Our solutions oriented approach to project management has resulted in new construction solutions and methods. Our collaborative, creative, and innovative project management style results in award winning projects that meet or exceed local requirements, maintain design intent, meet budgets and schedules, and have resulted in a list of construction “firsts” to our clients’ benefit. SIGAL pioneers a sustainable future as a founding partner of the USGBC.
