4 INFORMATION SHOWN IS DIAGRAMMATIC INCHARACTER AND DOES NOT NECESSARILY INDICATE EVERY REQUIRED OFFSET, FITTING, NOT SCALE THE DRAWINGS FOR DIMENSIONS. TAKE ALL DIMENSIONS, MEASUREMENTS,EQUIPMENT LOCATIONS, LEVELS, ETC FROM THE ARCHITECTURAL DRAWINGS AND FROM THEEQUIPMENT TO BE FURNISHED. PIPING MAY BE RELOCATED OR OFFSET FOR PROPERCLEARANCES OR TO AVOID CONFLICTS WITH OTHER TRADES. THE DESIGN INTENT ( , VELOCITIES, PRESSURE DROPS, VOLTAGE DROPS, ETC) CANNOT BE GREATLYALTERED WITHOUT THE APPROVAL OF THE ARCHITECT. THE COST OF THESE DEVIATIONS TOAVOID INTERFERENCE'S SHALL BE PART OF THE ORIGINAL CONTRACT SUBCONTRACTOR SHALL CONFER AND COOPERATE WITH ALL OTHER TRADES TOCOORDINATE THEIR WORK. COORDINATION SHALL INCLUDE, BUT SHALL NOT BE LIMITED TOMATERIALS AND EQUIPMENT ROUTED IN CEILING AND WALL CAVITIES, EQUIPMENTARRANGEMENT IN MECHANICAL SPACES, INCLUDING EQUIPMENT CLEARANCEREQUIREMENTS, ELEVATIONS AND DIMENSIONS OF STRUCTURAL MEMBERS AND OPENINGS,ETC.

5 THE CONTRACTOR SHALL NOTIFY THE ARCHITECT OF ANY FINAL INSTALLATION OF MATERIALS AND EQUIPMENT ON ACTUAL DIMENSIONS ANDCONDITIONS AT THE PROJECT SITE. FIELD MEASURE FOR MATERIALS AND EQUIPMENTREQUIRING EXACT FIT. NO EXTRAS WILL BE GIVEN FOR THE CONTRACTORS FAILURE TOFIELD OWNER OR ENGINEER ARE NOT RESPONSIBLE FOR THE CONTRACTOR'S SAFETYPRECAUTIONS OR FOR MEANS, METHODS, TECHNIQUES, CONSTRUCTION SEQUENCES, ORPROCEDURES REQUIRED TO PERFORM THE CONTRACTOR SHALL LOCATE ALL EQUIPMENT THAT MUST BE SERVICED, OPERATED, ORMAINTAINED IN FULLY ACCESSIBLE POSITIONS. EQUIPMENT SHALL INCLUDE (BUT NOTLIMITED TO) VALVES, MOTORS, CONTROLLERS, SWITCHGEAR, AND DRAIN POINTS IFREQUIRED FOR BETTER ACCESSIBILITY. FURNISH ACCESS DOORS FOR THIS DEVIATIONS FROM THE DRAWINGS MAY BE ALLOWED TO PROVIDE FOR BETTERACCESSIBILITY. ANY CHANGES SHALL BE APPROVED BY THE ARCHITECT AND CONSTRUCTIONMANAGER/GENERAL CONTRACTOR PRIOR TO MAKING THE CONTRACTOR SHALL PROVIDE ACCESS DOORS, WALL OPENINGS, ROOF OPENINGS ORANY OTHER CONSTRUCTION REQUIREMENT NEEDED TO ACCOMMODATE THE MECHANICALEQUIPMENT.

6 LOCATIONS OF THESE OPENINGS SHALL BE SUBMITTED IN SUFFICIENT TIME TOBE INSTALLED IN THE NORMAL COURSE OF CONTRACTOR SHALL COORDINATE ELECTRICAL REQUIREMENTS OF APPROVEDEQUIPMENT WITH THE ELECTRICAL CONTRACTOR PRIOR TO THE PURCHASE ANDINSTALLATION OF ANY ELECTRICAL GEAR OR CONTROL WIRING, THERMOSTATS, MOTORIZED DAMPERS AND CONDUIT ASSOCIATEWITH HVAC EQUIPMENT IS THE RESPONSIBILITY OF THE CONTRACTOR. THE CONTRACTORSHALL COORDINATE THE LOCATION OF ALL THERMOSTATS, ROOM SENSORS, ETC WITH THEARCHITECT AND ALL OTHER TRADES PRIOR TO INSTALLATION. IF A CONFLICT WITHMILLWORK, LIGHT SWITCHES, WINDOWS, ETC EXISTS, THE CONTRACTOR SHALL NOTIFY THEARCHITECT OF THE POTENTIAL INTERFERENCE PRIOR TO INSTALLATION. INSTALLTHERMOSTATS WITH PROTECTIVE LOCKING COVER, CENTERED AT 4'-0" ABOVE FINISHEDFLOOR, UNLESS OTHERWISE INDICATED. COMPLY WITH THE PROVISIONS OF THE AMERICANSWITH DISABILITIES ACT (ADA) AND THE TEXAS ACCESSIBILITY'S STANDARD (TAS).

7 ALL DIMENSIONS SHOWN ON THE DRAWINGS FOR DUCTWORK ARE NET INSIDE CLEARDIMENSIONS. FOR RECTANGULAR DUCT, THE FIRST FIGURE OF THE DUCT SIZE INDICATESTHE DIMENSION OF THE FACE SHOWN. VERIFY THAT THE DUCTWORK SPECIFIED WILL FIT INTHE SPACE AVAILABLE USING THE ARCHITECTURAL, STRUCTURAL AND ELECTRICALDRAWINGS AS REFERENCE PRIOR TO FABRICATION AND INSTALLATION. ROUND DUCT OFEQUAL NET INSIDE CLEAR AREA MAY BE USED IN LIEU OF RECTANGULAR TURNING VANES ON ALL RECTANGULAR SUPPLY, EXHAUST AND RETURNDUCTWORK INCLUDING THE TOP AND BOTTOM OF VERTICAL A LOCKING QUADRANT VOLUME DAMPER AT THE TAP OF EACH RUN-OUT TODIFFUSERS FOR BALANCING PURPOSES, UNLESS OTHERWISE INDICATED. THE RUN-OUTDUCT SIZE IS THE SAME SIZE AS THE DIFFUSER OR GRILLE NECK SIZE UNLESS SPACE IS NEEDED AS A RETURN AIR PLENUM IN CERTAIN AREAS. FOLLOW ALLAPPLICABLE CODES AS TO MATERIALS ALLOWED FOR USE IN AIR PLENUMS.

8 COORDINATEWITH THE GENERAL CONTRACTOR TO PROVIDE FREE RETURN OF AIR FROM ALL TO ARCHITECTURAL DRAWINGS FOR LOCATION OF ALL FIRE RATED WALLS ANDCEILINGS. PROVIDE FIRE DAMPERS AND/OR COMBINATION FIRE/SMOKE DAMPERS INDUCTWORK AT ALL LOCATIONS WHERE DUCTS PASS THROUGH FIRE RATED CONTRACTOR SHALL BE RESPONSIBLE FOR LOCATING AND PROVIDING FIREAND SMOKE DAMPERS. COORDINATE CONSTRUCTION REQUIREMENTS WITH OF ALL GRILLES, REGISTERS, DIFFUSERS AND CEILING DEVICES SHALL BEDETERMINED FROM THE ARCHITECTURAL REFLECTED CEILING PLANS AND WALL ALL CEILING DIFFUSERS AND GRILLE LOCATIONS WITH LOCATION OF DUCTWORK SHALL BE SHEET METAL FABRICATED IN ACCORDANCE WITH SMACNASTANDARDS. ALL DUCT WORK FROM AHU TO TERMINAL UNIT SHALL BE CONSTRUCTED TO 1" AND SEALED TO SMACNA CLASS A. DUCT WORK DOWN STREAM OF TERMINAL UNITSSHALL BE CONSTRUCTED TO 1/2" AND SEALED TO SMACNA CLASS C. SEAL ALL SEAMSWITH UL 181 MASTIC RATED FOR DX PIPING AS SPECIFIED, INCLUDING FILTER/DRYER, SIGHT GLASS,ISOLATION/CHARGING VALVES AND ALL APPURTENANCES PER MANUFACTURER'SRECOMMENDATIONS.

9 INSTALLATION SHALL BE ACCOMPLISHED IN A NEAT AND ORDERLYFASHION, AS APPROVED BY THE ENGINEER. COORDINATE FOR ROUTING OF DX PIPING, UPINSIDE OF WALLS, ETC. AS REQUIRED, TERMINATING AT AHU's. PROVIDE BRACING/ISOLATION,AS REQUIRED TO PREVENT VIBRATION OF DX PIPING INSIDE WALLS, ETC. SIZE, ROUTE ANDINSULATE DX PIPING PER MANUFACTURER'S RECOMMENDATIONS AND VIBRATION ISOLATORS FOR MOTOR DRIVEN EQUIPMENT UNLESS NOTEDOTHERWISE. PROVIDE ISOLATION AS INDICATED OR AS RECOMMENDED BY THE PIPES AND DUCTS SHOWN ON EACH floor PLAN MAY BE SHOWN WITH AN OFFSETFOR ALL PIPE AND DUCT PENETRATIONS THROUGH FIRE RATED BUILDING ELEMENTS WITHAN APPROVED FIRE PROOFING EQUIPMENT SHALL HAVE IDENTIFICATION TAGS. TAGS SHALL BE PLASTIC LAMINATE,WHITE FACE WITH 1/2" TALL BLACK LETTERS. THE TAG SHALL MATCH THE UNITDESIGNATIONS SHOWN ON THE CONTRACTOR SHALL EXPAND OR REDUCE DUCTS AT EQUIPMENT CONNECTIONS BASEDON THE EQUIPMENT PURCHASED, WITH TRANSITIONS NOT TO EXCEED 30 DEGREES.
