The eight-story, 175-room St. Regis Hotel originally opened in 1926 and is a historic landmark in downtown Washington, DC. The high-end hotel, located just two blocks from The White House, underwent a major 166,000 SF renovation, which involved:

The mechanical and electrical systems replacement included a complete removal and replacement of the central plant involving extensive BIM coordination. In addition, pipelining techniques were utilized to line the interior face of existing drain piping in the concrete slab above the main lobby’s intricate plaster ceiling. This method provided years of additional service life to a corroded piping system by avoiding ceiling space limitations and demolition of the plaster ceiling.
