What is self-performed work in construction?

Self-performed work is the part of a project a contractor completes with its own employees, equipment, and supervision, rather than subcontracting it to another company.

Self-performed work is work you do with your own people. A general contractor that pours its own concrete, frames, and installs doors and hardware is self-performing those trades and subcontracting the rest. A GC that subcontracts everything and only provides management and general conditions self-performs almost nothing. Most GCs land somewhere in between, and how much they self-perform shapes their risk, margin, and staffing.

Why contractors self-perform

  • Margin. The contractor keeps the trade's profit instead of marking up a sub's price.
  • Schedule control. Own crews can be moved to the critical path without negotiating with another company.
  • Quality. Early trades like concrete and framing set up everything after them.
  • Filling gaps. Small scopes that subs will not bid, or bid high, get done in-house.
  • Competitive pricing. On bid work, self-performing a major trade can make the difference on price.

The tradeoff is risk. When a sub runs over on labor, its subcontract price usually stays the same. When your own crew runs over, the loss is yours. Self-performed work also needs payroll, equipment, insurance, safety programs, and enough backlog to keep crews busy.

How it looks on a real job

Say a GC wins a $3.4M retail building. It subcontracts site work, roofing, MEP, and finishes, and self-performs concrete foundations and slab, rough carpentry, and doors, frames, and hardware. Those self-performed scopes are estimated at $610,000 in labor, material, and equipment.

On subcontracted work, the PM watches commitments and change orders. On self-performed work, the PM and superintendent also have to watch labor hours every week against the estimate. If the slab crew is tracking at 1,150 hours against 950 budgeted at the halfway point, the overrun is real money, and only weekly job costing shows it before the work is done. This is why self-performing contractors tend to need tighter field time tracking and cost codes than pure managers.

Federal rules on self-performance

On some federal set-aside contracts, how much you can subcontract is limited. Under FAR 52.219-14, Limitations on Subcontracting, a small business prime on general construction may not pay more than 85 percent of the amount it receives (excluding the cost of materials) to subcontractors that are not similarly situated entities. For special trade construction the limit is 75 percent. A similarly situated entity is a first-tier sub with the same small business program status that qualified the prime and that is small under the NAICS code assigned to the subcontract. Check the solicitation to confirm which clauses apply.

Common mistakes

  1. Pricing self-performed labor with optimistic production rates no crew has actually hit.
  2. Forgetting labor burden and small tools in the estimate.
  3. Self-performing a trade to save margin when there is no qualified foreman to run it.
  4. Not tracking self-performed costs separately from subcontracted costs, so margin problems hide in the totals.
  5. Missing subcontracting limits on set-aside work, which can create compliance problems.

Frequently asked questions

Do general contractors have to self-perform any work?

Not on most private jobs. Some public owners and federal set-aside contracts set limits on subcontracting or require a minimum share of work by the prime, so read the solicitation.

Is self-performing more profitable?

It can be, because you keep the trade margin, but it also carries the labor productivity risk. Profit depends on how well you estimate and manage your own crews.

What trades do GCs commonly self-perform?

It varies by company. Concrete, rough carpentry, doors and hardware, and general labor are common examples, while licensed trades like electrical and plumbing are more often subcontracted.

How does self-performed work show up in job costing?

As labor, material, and equipment costs under the relevant cost codes, rather than as a single subcontract commitment. It needs more detailed tracking.
