Why commissioning agents are hard to hire

Most qualified commissioning agents are booked on another project when you call, and the CxA lead sits on the critical path to turnover.

Why commissioning agents are hard to hire

Commissioning skill is built only on live, energized projects, and fewer people have that experience than there are projects that need them. If the CxA lead is not identified before Level 3 starts, the turnover date is at risk, so plan the search with the schedule.

Requirements

A qualified commissioning candidate has personally run scripts on energized equipment. We look for Level 4 and Level 5 experience: functional performance testing on integrated systems, and integrated systems testing at full load with the building running as it will in production.

Plenty of resumes list commissioning after a few Level 1 and 2 checks. In the screen we ask which systems the candidate scripted, what failed during ISAT, and what they changed afterward.

  • Level 1-2: factory and site acceptance, checklists, static verification
  • Level 3: startup and pre-functional testing of individual equipment
  • Level 4: functional performance testing across integrated systems
  • Level 5: integrated systems testing at load, including failure scenarios
  • Documentation discipline: scripts, issues logs, and owner turnover packages

Experience sources

Commissioning engineers learn on projects. Someone needs several full delivery cycles before they can own scripts on a hyperscale build, and each cycle runs a year or more, so the number of qualified people today depends on how much was built several years ago.

Most of them work at commissioning consultancies, owner-side Cx groups or MEP contractors, and most are booked on a named project when you call. They become available when that project finishes.

Cost of delay

An unfilled commissioning lead adds recruiting cost and moves the turnover date. When Level 4 slips, every downstream milestone slips with it: IT equipment install, customer acceptance, and the revenue start on the lease.

Work out that cost before you negotiate the fee. Our cost of vacancy calculator gives you a daily number for the role, including a schedule risk multiple for roles on the critical path.

Hiring plan

Work backwards from the date the owner takes the building. The CxA lead should be identified before Level 3 begins, so start the search well before you need scripts written.

We start with people whose builds in your region finish in the next quarter, because they are the ones free to move.

  • Start the CxA lead search before Level 3
  • Map candidates by project completion date
  • Give feedback within 48 hours of a submittal; other recruiters call these candidates every week
  • Price counteroffers into the plan before the first interview
  • Consider travel-based Cx agents when no one local is available

Questions

Questions

How long does it take to hire a commissioning agent?
It depends on who is coming off a project when you start and how fast you decide. Searches take longer in markets with few local Cx agents, so start the CxA lead search before Level 3.
Can we train commissioning talent internally instead of hiring?
You can train people for Level 1 to 3 work over a few delivery cycles. Owning Level 4 and 5 takes repeated integrated systems testing at load, and most owners do not run enough projects to build that in time for a live schedule.
What does a commissioning agent cost?
Pay depends on the metro and on whether the role is owner-side, consultancy or contractor. We benchmark against the companies you would recruit from in your metro, and a market map shows those ranges.
Should we use a commissioning consultancy instead of hiring?
A consultancy can run the scripts, but someone on the owner side still has to accept the building at turnover. Many programs have both: a consultancy running scripts and an owner-side Cx lead who signs off.
