Commissioning and Startup

Navigation: phase-workflows | index

Commissioning and startup is the bridge between mechanical completion and first production. It is consistently underestimated — both in cost and duration — because it sits at the boundary between the construction contract and the owner’s operations team. Neither side fully owns it, so it falls through the cracks unless planned explicitly.

Rule: Commissioning and startup costs belong in the owner’s project budget, not the GC’s GMP. The GMP ends at substantial completion. Everything from system turnover through first saleable production is an owner cost.


Phases from Mechanical Completion to First Production

Section titled “Phases from Mechanical Completion to First Production”
PhaseDefinitionWho LeadsDuration (Typical)
Pre-commissioningSystems checked for completeness before energizing — instruments calibrated, piping flushed, equipment inspectedGC with owner oversightConcurrent with late construction
Mechanical completion (MC)All construction work complete; systems capable of being tested; punch list issuedGC declares; owner acceptsMilestone, not a duration
CommissioningSystems energized and tested individually; equipment run uncoupled; functional checks against design specsOwner’s commissioning team or third-party commissioning agent4–12 weeks

Mechanical Completion Checklist (GC Deliverables)

Section titled “Mechanical Completion Checklist (GC Deliverables)”

Before declaring mechanical completion, the GC should confirm:

  • All equipment installed, secured, and lubricated per vendor specs
  • All piping systems hydrostatically tested and flushed; test records complete
  • All electrical systems tested (insulation resistance, continuity, overcurrent device settings)
  • All instruments calibrated; loop checks performed
  • HVAC systems balanced; TAB report submitted
  • Controls narratives and sequences of operation submitted and accepted
  • O&M manuals and spare parts delivered (per contract list)
  • As-built drawings submitted (redline markups at minimum; final CAD per contract)
  • Punch list issued and category A items closed before MC declaration
  • Equipment start-up by manufacturer’s representative completed (motors, compressors, chillers)
  • Training sessions completed per contract

Each major system (HVAC, refrigeration, process piping, electrical distribution, automation) should have a turnover package:

DocumentDescription
Punch list — Category A closedSafety and operability items; no MC without these
Punch list — Category B openNon-critical items; schedule for closure post-MC
As-built drawingsRedlines at MC; final drawings within 30–60 days
Equipment manuals (O&M)Vendor-issued; bound per system
Commissioning recordsStart-up reports, functional test results
Spare parts listWith quantity, vendor part numbers, on-hand count
Warranty documentationStart date, duration, vendor contact
Training completion recordsPer-system training confirmed

Commissioning costs are an owner project cost — they should not be embedded in the GMP. Budget them as a separate line item.

Project TypeCommissioning Cost (% of TIC)Notes
Basic light industrial / shell0.5–1.5%Simple systems; owner forces
CPG / automated packaging facility1.5–3.0%Equipment integration, controls testing
Food processing (sanitary systems)2.0–4.0%CIP verification, temperature mapping, drain verification
Cold storage / refrigerated processing2.5–4.5%Refrigeration system startup, temperature mapping required
Process manufacturing (complex utilities)3.0–6.0%Multi-system integration; longer commissioning window

What’s included in commissioning cost:

  • Owner’s commissioning manager or third-party commissioning agent
  • Vendor startup and commissioning support (often billed separately from equipment purchase)
  • Utilities consumed during testing (power, water, gas, compressed air)
  • Test materials and consumables
  • Punch list tracking and re-testing
  • Documentation preparation

F&B and CPG — Commissioning Requirements

Section titled “F&B and CPG — Commissioning Requirements”

Food and beverage and CPG facilities have regulatory and food safety commissioning requirements that are distinct from general industrial projects. These must be planned and budgeted before first production.

CIP (Clean-in-Place) systems must be verified before any food-contact production:

  • CIP circuit map completed and verified against as-builts
  • Flow velocity verification: >5 ft/sec in all circuits for turbulent cleaning
  • Temperature verification at circuit endpoints (not just supply): minimum 165°F for hot CIP
  • Chemical dosing verification: correct concentration at endpoint
  • Cycle time verification: all phases (pre-rinse, wash, rinse, sanitize, final rinse) timed
  • CIP return flow confirmed (no dead legs draining by gravity only)
  • Automated CIP system: sequence programmed, validated, and documented

CIP commissioning often requires a specialist contractor separate from the CIP skid vendor.

Temperature Mapping (Refrigerated / Frozen Facilities)

Section titled “Temperature Mapping (Refrigerated / Frozen Facilities)”

Required before first food product storage:

  • Temperature mapping protocol written (describes sensor placement, duration, conditions)
  • Mapping performed under worst-case conditions (full load, door openings, power interruption)
  • Alarm setpoints confirmed against mapping results
  • Temperature recording system verified and calibrated
  • Regulatory requirement: FDA 21 CFR 110 for refrigerated food; USDA FSIS for inspected plants

Duration: 3–7 days per space for a complete mapping study. Budget $5,000–$25,000 per refrigerated/frozen space depending on size and complexity.

  • All floor slopes confirmed draining to drains (no ponding under hose-down or production conditions)
  • Drain covers and traps installed and functional
  • Grease interceptors (if applicable) operational
  • Wastewater pre-treatment operational and within discharge permit limits before first production

This is frequently missed until operations begin — a wet floor that doesn’t drain properly fails USDA/FDA inspections and creates food safety liability.

  • Oil content test: ISO 8573-1 Class 1 (≤0.01 mg/m³) for product-contact air
  • Dew point test: pressure dew point ≤−40°C at distribution header
  • Particulate count test: Class 1 per ISO 8573-1
  • Stainless distribution confirmed (no copper or galvanized in food contact zones)

Third-party compressed air testing: $2,000–$5,000 per system. Required for SQF, BRC, FSSC 22000 audit compliance.

RequirementAuthorityTimingCost Range
USDA FSIS pre-operational inspectionUSDA FSISBefore first USDA-inspected production; can take 2–8 weeks for schedulingInspector time (covered by USDA); owner prep cost $5,000–$25,000
FDA facility registrationFDABefore first interstate shipment of foodFree; administrative cost only
Local health department pre-opening inspectionLocal jurisdictionBefore first production$200–$2,000 in fees
State environmental pre-operation permitState DEQ/EPAIf wastewater pre-treatment installedVaries; $1,000–$10,000

USDA FSIS timing risk: USDA inspection scheduling is outside the owner’s control. In some regions, slots are 4–8 weeks out. Start the scheduling process at mechanical completion, not after. A 6-week wait after commissioning is complete is a real production delay cost.

FSMA Prerequisite Programs — Must Be in Place Before First Production

Section titled “FSMA Prerequisite Programs — Must Be in Place Before First Production”

Under FSMA Preventive Controls for Human Food (21 CFR Part 117), these prerequisite programs must be documented and implemented before first production run, not after:

  • Sanitation controls (written sanitation procedures, monitoring, corrective actions)
  • Pest control program (third-party pest control active, monitoring stations in place)
  • Employee hygiene training records (GMP training documented)
  • Allergen control program (if applicable — segregation, dedicated lines, color-coded equipment)
  • Environmental monitoring program (swab protocol, lab contract in place)

Budget: $15,000–$40,000 in consultant fees to build these programs from scratch for a new facility. Large CPG companies with existing programs will adapt existing SOP templates at lower cost.

Production Trial Runs (Startup Waste Budget)

Section titled “Production Trial Runs (Startup Waste Budget)”

First production runs generate product that is typically held for testing before release or destroyed:

Facility TypeStartup Waste EstimateNotes
CPG / packaging line1–3 production days of outputLine efficiency low on first runs; quality holds
Food processing2–5 production daysCIP verification, sensory testing, micro testing before release
Cold/frozen processing3–7 production daysThermal process validation, temperature verification of first lots

Budget the value of this waste in OPC, not the GMP. On a 100,000 lb/day food facility, 3 days of startup waste at $2/lb = $600,000 in lost product value.


CPG / Packaging Line Startup (Non-Food-Safety Focus)

Section titled “CPG / Packaging Line Startup (Non-Food-Safety Focus)”

For CPG facilities without food safety regulatory requirements:

  • Site Acceptance Testing (SAT): structured testing of each line at installed location; pass/fail criteria defined in equipment purchase order
  • Line efficiency ramp-up: expect 50–70% OEE in first month; budget for operator learning curve
  • Controls integration testing: PLC/SCADA with plant historian, MES, ERP — these integrations almost always require more time than planned
  • Spare parts: commissioning often reveals missing spare parts; have budget for expedited procurement during startup window
