About this file
This is a Questions and Answers document regarding technical specifications for tank inspection work at Edwards AFB, accompanied by technical diagrams and photos. The document addresses six specific questions about Tank 5 at Facility #10337, covering pump access paths, scaffolding requirements, manway specifications, and electrical safety procedures.
The document clarifies that either of two 4-inch ports can be used for fuel removal, with contractors needing to coordinate with the base for fuel drainage through issue pumps. While a ladder with platform exists near the manway, no full tank-spanning platform is present, and contractors must follow OSHA/local safety requirements for tank access. Several technical specifications regarding manway hardware and bolting requirements cannot be provided by the government and must be verified with base personnel after contract award. The document specifies that electrical power to the tank must be turned off prior to manway opening, with contractors required to coordinate all safety requirements with base personnel.

1. What is the path to pump through (tank nozzle or associated piping)? Pictures in the previous report provided make this unclear, but assume 4-inch port on top of tank?
a. The answer to this depends on what they are asking about. If they are looking for an additional port for inserting a suction tube to remove any residual fuel, then likely either of the two 4” ports shown below is acceptable. The Contractor should coordinate with the base to drain as much fuel as possible through the issue pumps prior to this.
2. Will a scaffolding platform be required for tank entry?
a. Personnel accessing the tanks should follow all OSHA/local requirements and access the tank in a safe manner. There is a ladder with a platform next to the manway as shown in the below photo but no platform extends across the entire tank.
3. Based on the previous report provided, pictures of the manway show no external manway flange. Will standard bolts be needed to close the manway or will studs with nuts and washers be needed? Please clarify.
a. The Government cannot obtain this information. Contractors will need to coordinate and verify with base personnel after award.
4. What diameter and length are the current bolts for the manway?
5. New hardware requirements: B8 or B7 Teflon coated? Please specify based on questions above.
6. Will the facility have all electrical power off on the tank and perimeter prior to opening the manway?
a. Electrical power to tank should be turned off prior to opening the manway. Contractor will be required to coordinate with base personnel after award to ensure all safety requirements are met.
