What is a project labor agreement in construction?

A project labor agreement (PLA) is a pre-hire collective bargaining agreement with one or more unions that sets the terms of employment for everyone working on a specific construction project.

A project labor agreement is a single labor contract covering one project. Before work starts, the owner or its contractor signs with building trades unions, and every contractor and subcontractor on the job agrees to its terms: wages and benefits, hiring through union referral, work rules, dispute procedures, and usually a no-strike, no-lockout promise. The FAR defines a PLA as a pre-hire collective bargaining agreement with one or more labor organizations that establishes the terms and conditions of employment for a specific construction project.

Open-shop contractors can still work on PLA jobs, but they must follow the agreement for that project.

Federal PLA rules

Under FAR Subpart 22.5, a large-scale construction project is a federal construction project in the United States where the total estimated cost of the construction contract to the government is $35 million or more. For those projects, agencies shall require the use of PLAs by contractors and subcontractors doing construction on the project, unless an exception under FAR 22.504(d) applies. Below that size, agencies may require a PLA if they decide it advances economy and efficiency. For indefinite-delivery contracts, a PLA may be required order by order, including on orders of $35 million or more.

State and local governments set their own PLA policies, and private owners can choose PLAs on their own projects. PLA jobs on public work are often also prevailing wage jobs, so both sets of rules apply.

How a PLA works on a real job

Say an open-shop mechanical sub with 20 field employees wants to bid a federal courthouse renovation covered by a PLA. Before bidding, the estimator reads the agreement. It requires a letter of assent, hiring through the union hall after a set number of the sub's core employees, wage and benefit contributions at the agreement rates, and the agreement's grievance process.

The estimator prices labor at the PLA rates, including fringe contributions, and checks whether contributions for the sub's own employees would duplicate benefits the company already pays. Overhead for union reporting goes into the bid. On award, the PM sets up separate payroll codes for the job so certified payroll, union reports, and job cost all reconcile.

The decision to bid comes down to a few numbers: the labor cost difference under the PLA, the added admin time, and whether the sub can staff the job with the referral rules. Some open-shop firms find the math works on a big federal job; others pass. Either way, the decision should come from the agreement itself, not from assumptions about it.

Common mistakes

  1. Bidding without reading the PLA. Work rules, crew mix, and hiring terms change labor cost.
  2. Forgetting to flow the agreement down to lower-tier subs, who must sign on too.
  3. Missing the reporting. Union benefit fund reports run alongside certified payroll on public work.
  4. Assuming your normal crew mix and apprentice ratios apply.

Frequently asked questions

Do I have to be a union contractor to work on a PLA project?

No. Open-shop contractors can usually bid, but they must sign on to the agreement and follow its terms for that project, including hiring and benefit provisions.

When are PLAs required on federal projects?

Under FAR Subpart 22.5, agencies must require PLAs on large-scale construction projects, defined as a total estimated construction contract cost to the government of $35 million or more, unless an exception applies.

Is a PLA the same as prevailing wage?

No. Prevailing wage is a legal minimum pay rate on public work. A PLA is a labor agreement that sets wages, benefits, and work rules for one project. A job can have both.

Do PLAs apply to subcontractors?

Yes. On federal large-scale projects, the requirement covers contractors and subcontractors performing construction on the project.
