Commissioning costs vary based on project size, scope, complexity, and delivery method, with typical ranges providing budgeting guidance for various project types.
New Construction Commissioning typically costs 0.5% to 1.5% of total construction cost, with the percentage decreasing as project size increases due to economies of scale.
Project size impacts:
• Small projects (under $5 million): 1.0-1.5% of construction cost
• Medium projects ($5-20 million): 0.75-1.25% of construction cost
• Large projects ($20-100 million): 0.5-1.0% of construction cost
• Very large projects (over $100 million): 0.4-0.75% of construction cost
Scope variations affect costs:
• Fundamental commissioning (LEED prerequisite level): 0.5-0.75% of construction cost
• Enhanced commissioning (LEED EA Credit level including envelope): 0.75-1.25% of construction cost
• Comprehensive commissioning (all systems, envelope, extensive testing): 1.0-1.5% of construction cost
Project complexity influences:
• Simple buildings (warehouses, basic offices, retail): Lower end of ranges (0.5-0.75%)
• Moderate complexity (standard offices, schools, multi-family): Mid-range (0.75-1.0%)
• Complex buildings (hospitals, laboratories, data centers): Upper end of ranges (1.0-1.5% or higher)
Existing Building Commissioning (retro-commissioning or re-commissioning) typically costs $0.30 to $0.75 per square foot, with variation based on building type, age, and scope:
• Basic retro-commissioning: $0.30-0.45/SF
• Comprehensive retro-commissioning: $0.45-0.65/SF
• Retro-commissioning with capital improvements: $0.50-0.75/SF
Ongoing Commissioning costs $0.10 to $0.30 per square foot annually:
• Basic monitoring programs: $0.10-0.15/SF annually
• Standard ongoing commissioning: $0.15-0.25/SF annually
• Comprehensive continuous commissioning: $0.20-0.30/SF annually
Monitoring-Based Commissioning (MBCx) typically costs $0.15 to $0.25 per square foot annually for continuous monitoring with periodic testing and optimization.
Building Envelope Commissioning as a separate scope costs $0.15 to $0.40 per square foot of envelope area, depending on testing extent and complexity.
Cost factors increasing commissioning expenses:
• Geographic location (higher costs in major metropolitan areas)
• Project schedule compression (expedited review and testing)
• Extensive systems requiring commissioning
• Multiple buildings or distributed campuses
• High-performance or specialty building requirements
• Extensive travel requirements for remote locations
What’s included in commissioning costs:
• Commissioning authority professional fees
• Design review at multiple phases
• Submittal review
• Construction observation
• Pre-functional checklist review
• Functional test procedure development
• Functional testing execution
• Documentation and reporting
• Systems manual development (for enhanced commissioning)
• Operator training observation
• Post-occupancy activities
What’s typically NOT included (owner or contractor responsibilities):
• Contractor time supporting testing
• Equipment or system modifications correcting deficiencies
• Additional testing for repeatedly failing equipment
• Extended testing due to unavailable or non-functional systems
• Overtime charges for testing outside normal business hours
ROI considerations: While commissioning costs 0.5-1.5% of construction, it typically generates:
• Energy savings of 8-20% (10-30x cost over 10 years)
• Reduced callbacks and warranty costs (5-10x commissioning cost avoided)
• Extended equipment life (value 2-5x commissioning cost)
Budgeting recommendations: Owners should budget commissioning costs as separate line items in project budgets rather than expecting contractors to absorb costs. Early commissioning budget allocation (during project planning) ensures adequate funding and prevents value engineering that eliminates commissioning to meet budget shortfalls.
