CONTRACTOR TO VISIT SITE AND VERIFY ALL CLEARANCES BEFORE FABRICATION OF DUCTWORK AND PROVIDE ADDITIONAL OFFSET AND/OR CHANGES IN DUCT SIZES TO MEET FIELD CONDITIONS AND COORDINATE WITH ELECTRICAL, PLUMBING AND FIRE PROTECTION SUBCONTRACTOR BEFORE ANY CONSTRUCTION WORK 3, CONTRACTOR SHALL NOTIFY THE OWNER, ARCHITECT OR HI5 AUTHORIZED REPRESENTATIVE OF ANY DAMAGE TO THE EXISTING INSTALLATION BEFORE PROCEEDING WITH THE WORK 4. COORDINATE AIR DEVICE LOCATIONS WITH LIGHTING FIXTURES AND FIRE SPRINKLER HEADS. 5. DUCT DIMENSIONS SHOWN ON DRAWINGS ARE CLEAR INSIDE DIMENSIONS. 6. ALL SUPPLY AIR DIFFUSERS SHALL BE 4-WAY THROW UNLESS OTHERWISE NOTED. CONTRACTOR SHALL PROVIDE A COPY OF THE TEST AND BALANCE REPORT AT THE FINAL INSPECTION. THIS REPORT MUST BE REVIEWED AND APPROVED BY THE ENGINEER PRIOR TO THE FINAL ACCEPTANCE. 1. THE GENERAL CONTRACTOR 15 RESPONSIBLE FOR ALL TRADES INSTALLATION SCHEDULES. FIXED WORK SUCH AS DUCTWORK AND PLUMBING SHALL BE INSTALLED PRIOR TO ANY TRADE WORK THAT CAN BE EASILY RELOCATED OR OFFSET SUCH AS ELECTRICAL CONDUITS, SMALL WATER LINES ETC. 8. CONTRACTOR SHALL PROVIDE ALL SUPPLEMENTARY STEEL REQUIRED TO SUSPEND a MECHANICAL EQUIPMENT AND MATERIALS. ✓ t S. FLEXIBLE AND RIGID ROUND DUCT TAKE -OFFS FOR DIFFUSERS SHALL BE THE SAME SIZE AS DIFFUSER NECK MAXIMUM FLEXIBLE DUCT LENGTH SHALL BE 8'-0" 10. ALL MECHANICAL WORK SHALL MEET ALL THE REQUIREMENTS OF THE "2010 FLORIDA BUILDING CODE, MECHANICAL". 11. IT 15 THE RESPONSIBILITY OF THE MECHANICAL INSTALLER TO PATCH AND REPAIR ANY DUCT OPENINGS WHICH RESULT FROM THE RELOCATION OR ELIMINATION OF ANY EXISTING AIR DEVICES. THE PATCH IS TO BE OF A SIMILAR MATERIAL TO THE REPAIRED DUCT AND TO BE SEALED IN ACCORDANCE WITH SMACNA STANDARDS. 12. ALL EXHAUST DUCTS SHALL BE GALVANIZED SHEET METAL. IMPORTANT NOTES FOR CONTRACTOR AND SUBCONTRACTOR: ANY DISCREPANCIES OR OMISSIONS ON THESE DOCUMENTS MUST BE BROUGHT TO THE ATTENTION OF THE ARCHITECT PRIOR TO THE COMMENCEMENT OF CONSTRUCTION AND BID TO OWNER. FAILURE BY CONTRACTOR TO IDENTIFY DISCREPANCIES OR OMISSIONS WILL THEN BECOME THE RESPONSIBILITY OF THE CONTRACTOR. CONTRACTOR SHALL COORDINATE RELOCATED AIR DEVICE LOCATIONS ON SITE WITH THE NEW REFLECTED CEILING PLAN AS NEEDED. HVAC SYSTEM AND DUCTWORK IS EXISTING TO REMAIN WITHOUT MODIFICATIONS. LAYOUT SHOWN IN PLAN 15 SCHEMATIC ONLY AND MUST BE FIELD VERIFIED. THE HVAC CONTRACTOR SHALL FIELD VERIFY LOCATIONS OF THE EXISTING (E)AIR DEVICES, (E)RTU'5, (E)T-5TAT AND (E)DUCT WORK SEQUENCE OF OPERATIONS: UNIT SHALL CEASE OPERATION UPON DETECTION OF SMOKE.
