commissioning-closeout

# Commissioning & Closeout Skill This skill serves as the **capstone** for construction project management, integrating all trades and coordination skills to deliver a fully commissioned, documented, and turned-over project. Use this skill to navigate the systematic process of verifying building systems, completing punch lists, compiling closeout documentation, and transitioning the project to the owner. ## Quick Reference Tables ### Commissioning Phases | Phase | Key Activities | PM Responsibilities | |-------|----------------|---------------------| | Pre-Design | OPR development, CxA selection | Support owner, review scope | | Design | BOD review, Cx specs | Review specifications | | Construction | Pre-functional, FPT, issues | Coordinate, schedule, track | | Acceptance | Seasonal testing, final report | Verify completion, acceptance | | Post-Occupancy | Warranty support, 11-month walk | Callback coordination | ### Systems to Commission | System Category | Key Systems | Reference Skill | |-----------------|-------------|-----------------| | HVAC | Heating, cooling, ventilation, exhaust | [mechanical-plumbing-systems] | | Electrical | Power distribution, emergency, lighting | [electrical-systems] | | Plumbing | Domestic water, sanitary, specialty | [mechanical-plumbing-systems] | | Fire Protection | Sprinkler, fire alarm, smoke control | [fire-protection-systems] | | Building Envelope | Air barrier, waterproofing, thermal | [building-envelope-exterior] | | Low-Voltage | BAS, security, AV, nurse call | [low-voltage-technology] | | Vertical Transport | Elevators, escalators | [elevators-vertical-transportation] | | Specialty | Kitchen, lab, medical equipment | [equipment-division-11] | | Sustainable | Solar PV, EV, BESS, geothermal | [sustainable-systems] | ### Closeout Milestones | Milestone | Criteria | Key Deliverables | |-----------|----------|------------------| | Pre-Substantial | Systems operational, Cx near complete | Pre-punch complete | | Substantial Completion | Occupiable, life safety complete | Certificate of SC, TCO/CO | | Punch List Complete | All items resolved | Sign-off documentation | | Final Completion | All work/docs complete | Final CO, final payment | | Warranty End | 11-month walk complete | Warranty closeout | ### TAB Tolerances | Measurement | Tolerance | Notes | |-------------|-----------|-------| | Supply/Return Air | ±10% of design | Per terminal/zone | | Outside Air | 0 to +10% of design | Never less than design | | Exhaust Air | 0 to +10% of design | Never less than design | | Hydronic Flow | ±10% of design | Per terminal | | System Total | ±5% of design | Overall system | ### Closeout Documentation Checklist | Document | Responsibility | Timing | |----------|----------------|--------| | O&M Manuals | Contractor/Subs | Before SC | | As-Built Drawings | Contractor/Subs | Before FC | | Warranties | Contractor/Subs | At SC | | Training Records | Contractor | Before occupancy | | Commissioning Report | CxA | Before FC | | TAB Report | TAB Contractor | Before Cx FPT | | Final Lien Waivers | All parties | At final payment | ## Reference Files ### Commissioning Fundamentals -
