The U.S. Army Corps of Engineers requires acoustic upgrades—including sound-blocking board, transducers, white noise machines, door trim, and ceiling tiles—to improve speech privacy in a secure room at Building 2593. The performance location is 7701 Telegraph Road, Alexandria, Virginia 22315. A single required site visit will be held on Tuesday, September 1, starting with check-in at 1000. Contractors must be US citizens or nationals with a valid government ID and driver’s license to enter the facility. Quotes must be submitted electronically by email, as fax quotes will not be accepted.
