National Monument Grounds Post and Chain Replacement
EGI successfully completed this highly visible year-long project to preserve the historic landscape of our nation’s capital. With nearly 24 million visitors to the National Mall each year, the monument grounds were rapidly deteriorating. EGI installed more than five miles of post and chain fencing to protect the sod and divert pedestrian traffic to the designated walkways.
Rehabilitation of the U.S. Marine Corps Memorial "Iwo Jima"
As a subcontractor, EGI provided consulting services on this project to rehabilitate the entire Iwo Jima Memorial grounds. The project required that the area surrounding the Memorial be surfaced with a material to match the black sands present on the beaches of Iwo Jima, Japan. EGI collaborated with the General Contractor and Owner to value engineer a specialty black aggregate concrete that both matched the Iwo Jima sands and provided a substantial cost savings to the National Park Service.
In 2006, this project received awards from the Associated General Contractors of America and the International Concrete Repair Institute.
Greenhill Barn Renovation
EGI was the prime contractor for the restoration of the Greenhill and Waller Barns at the Smithsonian Institution’s National Zoological Parks Conservation and Research Center in Front Royal, VA. General rehabilitation and restoration on these animal facilities included plumbing, electrical, and mechanical improvements; doors and window replacement; roof replacement; fencing; concrete and stone; masonry; interior and exterior architectural repairs; and the installation of specialty animal care equipment.
National Zoo Life-Safety Upgrades
EGI was the prime contractor for this series of projects carried out at the National Zoo in Washington, DC. These projects included installation of fire suppression systems and permitting of utilities, demolition, sitework, installation of highly technical equipment, and complex scheduling issues to accommodate the public traffic and nature of the Zoo, as well as many animal-specific concerns.
Smithsonian Environmental Research Center - Emergency and Standby Power
EGI furnished and installed emergency generators and related electrical equipment to supply the Smithsonian Environmental Research Center with power in the event of an electrical outage. The initial work involved installing underground electrical infrastructure, site clearing, and pouring of concrete pads to support the new equipment. A crane was required to lift and set the 51,000 lb generator. Finally, the new emergency equipment was tied into the facility’s existing electrical systems. Exterior work included security fencing and landscaping. The total scope included installation of four emergency generators ranging in size from 350KW to 1,000KW.
Joint Base Anacostia Building 411
EGI performed this design/bid/build project to construct a new, 6,000+ sq ft. facility on top of existing office space. The new facility houses ADA-compliant men’s and women’s restrooms and locker rooms. Additionally, EGI constructed a new stair tower to provide access from the 1st floor to the 2nd floor. Specific work included demolition, MEP and life-safety systems, site work and utilities, structural steel, concrete and masonry, carpentry and framing, roofing elevators, doors and windows, and interior finishes.
