History; The HSC Foundation Headquarters

SIGAL Construction Corporation (SIGAL) has provided construction services in the Washington, DC area since 1977. As one of the area’s leading construction firms, SIGAL has a documented history of providing clients with award winning preconstruction, general contracting, construction management, Design-Build, and sustainable construction services.

With roots firmly established in the interiors market, SIGAL has been responsible for some of the most difficult and challenging tenant projects throughout the Washington area. Throughout its history, SIGAL has built out millions of square feet of diverse tenant space for a variety of clients. These include, but are not limited to, several prestigious law firms, Fortune 500 and Global 1000 companies, corporations, institutions of higher learning, and government agencies. 

In addition, SIGAL has performed renovations of all types. Whether the project was a major renovation with replacement of building systems, historical restoration, occupied renovation or a unique combination thereof, SIGAL has been known as an industry leader in modernizing complex structures. Many of these projects were accomplished in occupied buildings with SIGAL’s commitment to minimizing disruption to ongoing building activities.

Following continued success with interiors and renovations, SIGAL entered the base building market in the early 1980’s. Since then, base building has become a cornerstone of SIGAL’s vast portfolio. To this day, SIGAL continues to provide preconstruction and construction services for some of DC’s landmark buildings.

As an industry leader, SIGAL was a founding member of the US Green Building Council (USGBC), and was part of the original committee that helped spearhead USGBC’s LEED® green building rating system. SIGAL’s current offices in Arlington are LEED-CI Silver which was the first LEED-CI project of any rating level in Arlington County. SIGAL continues to build upon its pioneering commitment to a green future by helping clients incorporate LEED® certifications into their buildings and spaces.

Our collaborative, creative, and innovative project management style is the foundation to delivering 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. The list of “SIGAL Firsts” includes project types as well as construction methods and includes the first vertical expansion of a commercial building and the first façadist renovation in Washington, DC (Bond Building), the first use roof-top mounted cranes in Washington, DC (One Metro Center), the first NetZero School and Insulated Form Concrete construction project on the East Coast (Discovery Elementary School), and the first LEED CI Certified office space in Arlington County (SIGAL Corporate Offices).

SIGAL prides itself in providing award-winning service, receiving many local and national awards from the key industry associations. These include but are not limited to the Washington Business Journal, Washington Building Congress, NAIOP DC|Maryland, NAIOP Northern Virginia, and Associated General Contractors of America.
