GENERAL NOTES: (APPLIES TO MECHANICAL DRAWINGS):

THE LOCATION OF EXISTING UNDERGROUND UTILITIES IS SHOWN IN AN APPROXIMATE WAY ONLY.

DETERMINE THE EXACT LOCATION OF ALL EXISTING UTILITIES BEFORE COMMENCING WORK. REPAIR ALL

DAMAGES OCCASIONED BY FAILURE TO EXACTLY LOCATE AND PRESERVE ANY AND ALL UNDERGROUND

UTILITIES.

MAINTAIN MINIMUM OF 3'-0" COVER OVER UNDERGROUND CHILLED WATER MAINS.

PROVIDE AN AIR VENT AT THE HIGH POINT OF EACH DROP IN THE HEATING AND CHILLED WATER SYSTEMS.

UNLESS OTHERWISE NOTED, ALL PIPING AND DUCTWORK IS OVERHEAD.

INSTALL PIPING AND DUCTWORK SO THAT ALL VALVES AND DAMPERS ARE ACCESSIBLE.

COORDINATE ALL MECHANICAL WORK WITH ELECTRICAL WORK, ETC., SHOWN ON OTHER DRAWINGS.

EXCEPT AS OTHERWISE SHOWN, LOCATE ALL ROOM THERMOSTATS 4'-0" (CENTERLINE) ABOVE FINISHED FLOOR ADJACENT TO THE ROOM LIGHT SWITCH. NOTIFY THE ENGINEER OF ANY ROOMS

WHERE THE ABOVE LOCATION CANNOT BE MAINTAINED OR WHERE THERE IS A QUESTION ON LOCATION.

MAINTAIN MINIMUM 6'-8" CLEARANCE TO UNDERSIDE OF PIPES, DUCTS, CONDUIT, SUSPENDED EQUIPMENT,

ETC., THROUGHOUT ACCESS ROUTES IN MECHANICAL AND ELECTRICAL ROOMS.

CERTAIN ITEMS SUCH AS CLEANOUTS, ACCESS DOORS, RISE AND DROPS IN DUCTWORK, ETC., ARE INDICATED

ON THE DRAWINGS FOR CLARITY OR A SPECIFIC LOCATION REQUIREMENT AND SHALL NOT BE INTERPRETED

AS THE EXTENT OF THE REQUIREMENTS FOR THOSE ITEMS. THE CONTRACTOR SHALL BE RESPONSIBLE FOR

THESE ITEMS AS REQUIRED ELSEWHERE IN THE CONTRACT DOCUMENTS.

EQUIPMENT CONNECTION SIZES MAY DIFFER FROM INDICATED DUCT OR PIPE SIZES. PROVIDE APPROPRIATE

TRANSITIONS WHERE REQUIRED.

THESE DRAWINGS ARE DIAGRAMMATIC AND ALL OFFSETS, FITTINGS, TRANSITIONS AND ACCESSORIES ARE

NOT NECESSARILY SHOWN. COORDINATE THE INSTALLATION OF ALL PIPING, DUCTWORK, EQUIPMENT AND

OTHER WORK WITH ALL OTHER TRADES.

IT IS THE INTENT THAT ALL WORK SHALL BE COMPLETE IN EVERY RESPECT AND THAT MATERIAL OR WORK

SPECIFICALLY NOT INDICATED ON DRAWINGS, BUT NECESSARY TO COMPLETE THE WORK, SHALL BE

FURNISHED.

EXACT LOCATION OF DIFFUSERS, REGISTERS AND GRILLES PROVIDED IN CEILING SHALL BE COORDINATED

WITH EXISTING CEILING.

REFER TO AIR DEVICE SCHEDULES FOR SIZE OF DUCT FROM BRANCH DUCT TO NECK OF AIR DEVICE.

ALL BRANCH DUCT RUNOUTS TO AIR DEVICES SHALL BE PROVIDED WITH

VOLUME DAMPERS.

MATERIAL, EQUIPMENT, INSTALLATION AND PROCEDURES SHALL BE IN STRICT ACCORDANCE WITH THE

APPLICABLE REQUIREMENTS OF THE LATEST CURRENT EDITION OF THE REFERENCED DOCUMENTATION.

REGULATIONS OF LOCAL AUTHORITIES HAVING JURISDICTION.
