Since our firm’s inception in 1955, Towill has served as both a prime contractor and a subcontractor on hundreds of contracts for Federal Government agencies. This includes contracts issued by Department of Defense (DoD) agencies, including the U.S. Navy, U.S. Coast Guard, U.S. Marines, U.S. Air Force, and U.S. Army Corps of Engineers. Towill has successfully provided mapping and surveying services for these DoD agencies; we intimately know the necessary technical standards, administrative procedures, and expectations. We are committed to working side by side with our clients solve complex surveying and engineering challenges.
