THE CONTROL SYSTEM INDICATED TO BE REMOVED, SHALL BE ENTIRELY REMOVED AND REPLACED, INCLUDING THE CONTROL SYSTEM, CONTROL WIRING, PNEUMATIC TUBING AND ALL ASSOCIATED ACCESSORIES. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO COORDINATE ALL SHUTDOWNS OF AIR HANDLING, CHILLED WATER, HOT WATER, STEAM, ECT. SYSTEMS WITH CORNELL UNIVERSITY FACILITY PERSONNEL FOR TIE-IN CONNECTIONS. ALL SHUT DOWNS WILL OCCUR DURING NIGHTS OR WEEKENDS. THE CONTRACTOR SHALL ASSIST THE UNIVERSITY PERSONNEL IN SHUTTING DOWN, DRAINING, VENTING, ECT. OF SYSTEM TO FACILITATE THE INTENDED WORK. IT IS THE REQUIREMENT OF THE PROJECT THE CONSTRUCTION WORK BE PHASED TO FACILITATE MINIMUM IMPACT TO THE NORMAL OPERATION OF THE FACILITY. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO THOROUGHLY REVIEW THE GENERAL CONDITIONS FOR THE PHASING REQUIREMENTS. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO PROVIDE FOR ALL TEMPORARY SERVICES (SUPPLY AIR, RETURN AIR, EXHAUST AIR, CHILLED WATER, HOT WATER, STEAM, CONDENSATE, AND CONTROL SYSTEMS) TO FACILITY PHASING REQUIREMENTS WITHOUT INTERRUPTION OF THE HVAC SYSTEMS. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO COORDINATE THE LOCATIONS OF ALL ROOM TEMPERATURE SENSORS AND OCCUPANCY WITH THE OWNER/ENGINEER. THE CONTRACTOR SHALL SCHEDULE A WALK THROUGH WITH THE OWNER/ENGINEER TO LOCATE SENSOR LOCATIONS PRIOR TO INSTALLATION. THE TEMPERATURE SENSORS SHALL BE INSTALLED IN ALIGNMENT WITH ELECTRICAL, FIRE, AND OTHER DEVICES WHEN LOCATED ON COMMON WALLS. THE OCCUPANCY SENSORS SHALL BE INSTALLED IN ORDER TO PROVIDE COMPLETE COVERAGE OF THE WORK AREAS. THE MOUNTING HEIGHT FOR ALL ROOM THERMOSTATS OR SENSORS SHALL BE 48 IN. TO TOP OF THE COVER. CONTRACT DOCUMENTS INDICATE REPLACEMENT OF ALL SENSORS, RELAYS, SAFETIES, ETC. IN ORDER TO ALIGN THE EXISTING SYSTEMS WITH CORNELL STANDARDS. CONTROL CONTRACTOR INSTALLING THE NEW CONTROL SYSTEMS SHALL INDICATE/REFLECT ANY EXISTING SENSORS WORKING CORRECTLY TO BE REUSED ON THE AS-BUILT DOCUMENTS. A. B. C. D. E. F. G.
