ALL ELECTRICAL CONNECTIONS MUST BE TIGHTENED TO THE RECOMMENDED TORQUE SETTINGS TO PREVENT LOOSE CONNECTIONS. 32. CONTROL SYSTEMS MUST BE CONFIGURED TO ENABLE THE INTENDED FUNCTIONALITY OF THE VRF SYSTEM, INCLUDING INDIVIDUAL ZONE TEMPERATURE CONTROL, CENTRALIZED MANAGEMENT, AND INTEGRATION WITH OTHER BUILDING MANAGEMENT SYSTEMS IF REQUIRED. ALL CONTROL CABLES MUST BE CLEARLY LABELED AND ROUTED TO AVOID ELECTROMAGNETIC INTERFERENCE. 33. UPON COMPLETION OF THE INSTALLATION, A COMPREHENSIVE COMMISSIONING PROCESS MUST BE CONDUCTED BY A QUALIFIED SPECIALIST. THIS INCLUDES VERIFYING REFRIGERANT PRESSURES, CHECKING ALL CONTROL FUNCTIONS, AND ENSURING THAT EACH UNIT IS OPERATING WITHIN THE RECOMMENDED PERFORMANCE PARAMETERS. 34. A DETAILED RECORD OF THE INSTALLATION, INCLUDING PIPING LAYOUTS, WIRING DIAGRAMS, AND REFRIGERANT CHARGE DATA, MUST BE SUBMITTED AS PART OF THE HANDOVER DOCUMENTATION. OPERATION AND MAINTENANCE MANUALS, ALONG WITH ANY MANUFACTURER’S CERTIFICATES, SHOULD ALSO BE INCLUDED TO SUPPORT FUTURE MAINTENANCE ACTIVITIES. 35. ADEQUATE CLEARANCE MUST BE PROVIDED AROUND BOTH INDOOR AND OUTDOOR UNITS TO ALLOW FOR SAFE SERVICING, MAINTENANCE, AND REPLACEMENT. ENSURE THAT THERE IS SUFFICIENT SPACE FOR THE REMOVAL AND REPLACEMENT OF KEY COMPONENTS SUCH AS COMPRESSORS, FANS, AND FILTERS. FIRE PROTECTION 1. ALL GAPS AROUND SERVICE PENETRATIONS MUST BE FULLY FIRE-STOPPED TO MAINTAIN THE FIRE RESISTANCE OF THE WALL, FLOOR, OR CEILING IN WHICH THEY ARE LOCATED. THE MAIN CONTRACTOR MUST ENGAGE A CERTIFIED FIRE-STOPPING SPECIALIST TO INSTALL THE FIRE-STOPPING MATERIALS TO ENSURE COMPLIANCE WITH THE MANUFACTURER’S CERTIFIED CONSTRUCTION DETAILS. FIRE-STOPPING SHOULD BE INSTALLED IN ACCORDANCE WITH BS EN 1366 AND OTHER APPLICABLE REGULATIONS AND STANDARDS. ANY OPENINGS THAT NEED TO BE SEALED MUST ADHERE TO THE FIRE RESISTANCE, SMOKE CONTAINMENT, AND ACOUSTIC PERFORMANCE RATINGS AS SPECIFIED BY THE DESIGN. 2. THE MECHANICAL CONTRACTOR SHALL BE RESPONSIBLE FOR THE SUPPLY AND INSTALLATION OF FIRE COLLARS, FIRE DAMPERS, SMOKE DAMPERS, AND COMBINED FIRE AND COLD-SMOKE MOTORIZED DAMPERS WHERE REQUIRED BY THE DESIGN OR LOCAL CODE. ALL FIRE AND SMOKE DAMPERS MUST BE INSTALLED AND TESTED IN COMPLIANCE WITH BS EN 1366-2 AND SHOULD BE FITTED WITH APPROPRIATE ACCESS FOR MAINTENANCE AND INSPECTION. ENSURE THAT EACH DAMPER IS INSTALLED IN ACCORDANCE WITH THE MANUFACTURER'S INSTRUCTIONS AND CERTIFIED CONSTRUCTION DETAILS TO ACHIEVE THE SPECIFIED FIRE AND SMOKE RESISTANCE. CONFIRM ALL DAMPERS ARE INTERFACED WITH THE BUILDING’S FIRE ALARM SYSTEM AND THAT FAIL-SAFE POSITIONS ARE SET AS PER THE FIRE STRATEGY. 3. MECHANICAL SERVICE PENETRATIONS, SUCH AS PIPES AND DUCTS, THAT PASS THROUGH FIRE-RATED ELEMENTS MUST BE FITTED WITH PROPRIETARY FIRE COLLARS, FIRE SLEEVES, OR WRAPS AS PER THE MANUFACTURER’S RECOMMENDATIONS AND LOCAL FIRE CODES. ALL PROPRIETARY COLLARS AND WRAPS SHOULD BE BS EN 1366 CERTIFIED AND INSTALLED IN ACCORDANCE WITH APPROVED CONSTRUCTION DETAILS. FIRE COLLARS SHOULD HAVE THE CORRECT INTUMESCENT MATERIALS TO PROVIDE THE SPECIFIED LEVEL OF PROTECTION BASED ON THE SERVICES PASSING THROUGH. 4. THE MECHANICAL CONTRACTOR SHALL ENSURE THAT ALL POWER, CONTROL, AND FIRE ALARM WIRING ASSOCIATED WITH FIRE COLLARS, SMOKE DAMPERS, AND FIRE DAMPERS IS PROPERLY COORDINATED WITH THE ELECTRICAL CONTRACTOR AND COMPLIES WITH THE REQUIREMENTS OF BS 5839 (FIRE DETECTION AND ALARM SYSTEMS). ENSURE APPROPRIATE FIRE-RESISTANT CABLE MANAGEMENT SYSTEMS ARE IN PLACE FOR ALL FIRE-CRITICAL CONTROL WIRING, WITH SEGREGATION FROM GENERAL ELECTRICAL SERVICES WHERE REQUIRED. THE FIRE ALARM SYSTEM MUST BE TESTED AND COMMISSIONED WITH ALL DAMPERS, FIRE COLLARS, AND OTHER INTERFACED EQUIPMENT TO ENSURE COMPLETE FUNCTIONALITY IN BOTH NORMAL AND FIRE SCENARIOS. 5. THE MAIN CONTRACTOR MUST ENSURE THAT ALL FIRE-STOPPING WORKS ARE CERTIFIED BY THE INSTALLATION SPECIALIST AND PROVIDE ALL RELEVANT CERTIFICATION AND DOCUMENTATION UPON COMPLETION. ALL FIRE AND SMOKE DAMPERS, FIRE COLLARS, AND FIRE-STOPPING INSTALLATIONS SHOULD HAVE A DETAILED COMMISSIONING REPORT, INSTALLATION CERTIFICATES, AND OPERATION & MAINTENANCE MANUALS SUBMITTED AS PART OF THE HANDOVER DOCUMENTATION. 6. EACH FIRE AND SMOKE ZONE SHOULD BE CLEARLY IDENTIFIED ON THE DRAWINGS AND COORDINATED WITH THE BUILDING’S OVERALL FIRE STRATEGY. DAMPERS, COLLARS, AND OTHER FIRE-STOPPING MEASURES SHOULD BE POSITIONED TO ENSURE INTEGRITY BETWEEN SEPARATE FIRE AND SMOKE CONTROL ZONES. 7. THE DESIGN AND INSTALLATION OF ALL FIRE-STOPPING, COLLARS, AND DAMPERS MUST CONSIDER FUTURE ACCESS FOR MAINTENANCE, INSPECTION, AND REPLACEMENT. ACCESS DOORS AND PANELS FOR FIRE AND SMOKE DAMPERS SHOULD BE CLEARLY MARKED AND PROVIDE SUFFICIENT SPACE FOR SAFE OPERATION AND MAINTENANCE. 8. THE FIRE PROTECTION STRATEGY AND NOTES SHOULD BE COORDINATED WITH ARCHITECTURAL AND STRUCTURAL DRAWINGS TO ENSURE THERE ARE NO CLASHES AND THAT THE DESIGN INTENT IS MAINTAINED THROUGHOUT. REGULAR COORDINATION MEETINGS BETWEEN THE MAIN CONTRACTOR, MEP CONTRACTOR, AND FIRE-STOPPING SPECIALIST ARE RECOMMENDED TO ENSURE THAT ALL FIRE AND SMOKE PROTECTION MEASURES ARE INSTALLED AND CERTIFIED CORRECTLY. 9. IT IS THE RESPONSIBILITY OF BOTH THE MAIN CONTRACTOR AND THE MECHANICAL CONTRACTOR TO OBTAIN AND FULLY REVIEW THE SIGNED- OFF FIRE COMPARTMENT DRAWINGS AND FIRE ENGINEERING STRATEGY FROM THE ARCHITECT AND FIRE ENGINEER PRIOR TO COMMENCING THE PRODUCTION OF THE WORKING DRAWINGS. ALL DETAILS WITHIN THE FIRE COMPARTMENT DRAWINGS, SUCH AS FIRE RESISTANCE RATINGS, COMPARTMENTATION LINES, AND FIRE ESCAPE ROUTES, MUST BE CLEARLY UNDERSTOOD AND INTEGRATED INTO THE WORKING DRAWINGS TO ENSURE COMPLIANCE WITH THE FIRE STRATEGY AND REGULATORY REQUIREMENTS. ANY DISCREPANCIES OR MISSING INFORMATION MUST BE BROUGHT TO THE ATTENTION OF THE DESIGN TEAM FOR CLARIFICATION BEFORE PROCEEDING.
