GENERAL NOTES

OFFSET WHERE REQUIRED TO ALLOW CLEARANCE OF DUCTS, ELECTRICAL CONDUIT, OUTLET BOXES, BEAMS, ETC. TO AVOID INTERFERENCE WITH THE WORK OF OTHER TRADES. TO INCREASE HEAD UNDER PIPING OR TO IMPROVE THE APPEARANCE OF PIPE WORK, THIS CONTRACTOR SHALL OFFSET ANY PIPING AS DIRECTED BY THE ARCHITECT/ENGINEER AND SHALL PROPERLY DRAIN OF VENT SAME WHERE NECESSARY. MAKE ALLOWANCES IN THE

BID THERETO. 02/04/2020

THIS CONTRACTOR SHALL FIELD VERIFY LOCATIONS FOR ALL DUCTWORK AND PIPING FOR DATE THE INSTALLATION PRIOR TO FABRICATION.

THIS CONTRACTOR SHALL COORDINATE HIS WORK WITH THE OTHER CONTRACTORS ON THE PROJECT AND INSTALL MECHANICAL SYSTEMS IN A MANNER WHICH WILL CONFORM TO STRUCTURE, KEEP PASSAGEWAYS AND OPENINGS CLEAR, PRESERVE HEAD ROOM, CLEAR LIGHT FIXTURES AND NOT COVER UP JUNCTION BOXES. THIS CONTRACTOR SHALL MAKE OFFSETS BKB RJA 19590 IN PIPING OR DUCTWORK TO AVOID INTERFERENCE WITH OTHER TRADES, AT NO ADDITIONAL COST TO THE OWNER, WHEN SO DIRECTED BY THE ARCHITECT/ENGINEER.

WHERE PIPING IS CONNECTED TO EQUIPMENT OR FIXTURES THAT ARE BEING REPLACEMENT REMOVED, THE PIPING SHALL BE REMOVED COMPLETELY (UNLESS NOTED OTHERWISE) FROM THE REMODELED SPACE AND CAPPED AT OR NEAR THE MAINS. PLUMBING PIPING THAT IS LOCATED IN A TO BE REMOVED SHALL BE REMOVED (IF NOT ACTIVE) AND CAPPED AT NORTH DAKOTA DEPARTMENT OF TRANSPORTATION THE MAIN LINE OR OUT OF THE REMODELED SPACE.
