About this file
The document is a Q&A for the Pipe Video Inspection contract opportunity, Solicitation Number FA449724R0006, issued by the Department of the Air Force Air Mobility Command. The contract requires the contractor to provide all labor, materials, tools, and equipment necessary for storm drain cleaning and TV inspection of approximately 35,000 LF of storm water pipes beneath or near airfield pavements at Dover AFB. The Q&A addresses questions about the longest linear footage span of piping between access points, which is approximately 1,000 feet for a 60-inch line. The contract appears to be focused on inspecting the storm water pipe system for potential defects.
