Inquiry #7: In reference to bid item 58 Relocate Fire Hydrant, I cannot locate this work on any layouts.

Or if it is being moved upstream or downstream on the watermain which would require capping the old tee, installation of new tapping sleeve, new valves and so forth. Please provide a layout of the fire hydrant relocations.
