Sienna Park ~ Arlington, Virginia

This six-story mixed-use property features 205,550 gsf 188 condominium units, 14,600 gsf office space, and 32,600 gsf retail space. The property was formerly the site of a Safeway grocery store and is now part of the Columbia Pike Special Revitalization District and will meet Arlington County’s new Form Based Code zoning regulations. The property will include over 400 spaces in three levels of underground parking. TCE’s waterproofing consultation for the new building construction and underground parking structure included the evaluation of architectural drawings and specifications, making recommendations, providing drawings and direction for details and materials as necessary, and providing field inspection services for construction quality control. TCE further provided consulting and inspection services for this project to review the waterproofing design including the building facade, windows, and roof. The design included all horizontal, vertical and below grade elements that require waterproofing such as, but not limited to, foundation walls, garages, elevator pits, plaza areas, and roofing.
