Yesterday’s Ask DCist feature addressed a weird, metallic, pulsating noise that appeared to be emanating from the HUD building in Southwest Washington, and could be heard clearly as far away as Eastern Market. All signs pointed to a busted steam pipe on the HUD roof, and indeed, U.S. General Services Administration spokesperson Michael McGill has since confirmed for us that at 3:30 a.m. on Monday, GSA received a call that a valve malfunction at the HUD building was causing built up pressurized steam to escape from the steam system, resulting in the loud noise. A repair crew was dispatched to make an adjustment to the valve, and the HUD building was open for business at its regular 8 a.m. start time on Monday.
