The Contractor (Design/Builder) shall be responsible in properly protecting all Fuel Oil Supply/Return piping regardless of it being aboveground or belowground with particular attention given in instances where the ground above the piping is a roadway surface serving Vehicular Traffic. It shall also be the responsibility of the Contractor to provide protection for the Fuel Oil Storage Tank and its Fuel Distribution Piping. The Contractor shall provide all analysis, back-up data, and assumptions to justify and verify his design and construction approach.

F. Protection of Fuel Oil Pipe with Pipe Sleeve - Acceptable method of protecting pipe subjected to physical loading is by pipe sleeve.
