Grunley Construction Company is heading a project to renovate the exterior of the U.S. Custom House in Penn’s Landing to make the building more energy efficient. The Customs House will get new exterior lighting with energy-efficient fixtures, a high-efficiency boiler and “green” roof. (Attempts to contact Grunley Construction to deduce just what “green” means in this case have thus far been unsuccessful.) Other repair work includes heavy restoration of masonry, replacement of all windows and a reconstruction of the front entrance. This 17-story building, which dominates an entire city block, is utilized by numerous federal agencies. Despite the onslaught of scaffolding currently swallowing the building, work within continues uninterrupted and when finished, we hope this $23.8M restoration looks as good as its price tag.
