IMF Concordia, 1250 New Hampshire Avenue, NW

Renovation of an existing apartment building into an extended stay hotel for International Monetary Fund guests.  Originally constructed in 1965, the building is centrally located between Dupont Circle and Washington Circle, and features 121 guest suites with fully equipped kitchens, a fitness center, and rooftop pool.  The project scope included extensive structural modifications to the existing cast-in-place concrete structural system. 

Structural modifications included demolishing the elevator core and rebuilding it into a larger configuration at a new location.  Two new stair towers were added within the building footprint to meet current egress requirements.  The relocated elevator core and added stair towers are supported on new mini-pile foundations designed to incorporate the existing footings and minimize demolition. 

Concrete structures were added at the roof level over the new elevators and stairs.  The entire fa├žade was removed and replaced with a curtain wall and cast-stone system, and includes a new entrance canopy.  The renovated building has achieved LEED Gold certification.
