Contracts

What is prequalification in construction?

Prequalification is the screening an owner or general contractor does before inviting a contractor or subcontractor to bid, checking finances, experience, safety, insurance, and bonding to make sure the firm can handle the work.

Prequalification (prequal) is the gate before the bid. An owner or GC sends a questionnaire, the contractor fills it out with documents attached, and the reviewer decides whether the firm gets on the bid list and for what size of job. The purpose is to avoid awarding work to the lowest number from a company that cannot finish it.

Owners prequalify GCs, and GCs prequalify subs. Public agencies often have formal prequal rules for certain project types. Private GCs set their own, and many use online portals that store each sub's data year to year.

What a prequal form asks for

  • Company basics: legal name, years in business, ownership, licenses, and trade.
  • Financials: reviewed or audited statements, revenue, working capital, and bank references.
  • Bonding: surety name, single job and aggregate bond capacity.
  • Insurance: coverage limits and a sample certificate of insurance.
  • Safety: experience modification rate, injury rates, and written safety program. Recordable data comes from the OSHA 300 log.
  • Experience: recent similar projects with references.
  • Legal history: claims, liens, litigation, and any debarment.
  • Workload: current backlog and key staff.

How it works on a real job

Say a GC is pursuing a $22 million school and needs a qualified mechanical sub. It sends a prequal to eight mechanical firms. One small firm has great references but $600,000 of working capital and a bond line that tops out well below the mechanical package. The GC approves it for packages under a set size and leaves it off this one.

Another firm has strong financials but a safety record that fails the GC's threshold. The GC asks for its corrective action plan, and the firm explains that one serious incident three years ago drove the number. With the plan reviewed, the firm gets approved with a safety condition. The prequal is not just pass or fail. It sets the size and terms of work a firm can bid.

Common mistakes

  1. Sending the same stale form every year. Reviewers notice old financials and expired certificates.
  2. Leaving questions blank. A blank usually scores as a no.
  3. Hiding claims or litigation. They show up in background checks, and the omission hurts more than the claim.
  4. Not knowing your own numbers. If the owner cannot explain working capital, the reviewer wonders who runs the money.
  5. GCs skipping prequal on small packages, which is exactly where weak subs slip in.

Prequal is a two-way street. A sub reviewing a GC's prequal form learns a lot about how that GC runs jobs: what it checks, what it ignores, and how seriously it takes safety and paperwork. Subs can and should ask GCs for payment history references before bidding their work.

Frequently asked questions

Who requires prequalification?

Owners prequalify general contractors, especially on public and large private work. General contractors prequalify subcontractors. Some suppliers and sureties have similar reviews.

How long is a prequalification good for?

It depends on the owner or GC. Many require updates annually or whenever financial statements or insurance change.

Is prequalification the same as being a responsible bidder?

They are related. Prequal screens firms before bidding. A responsible bidder determination often happens after bids, checking that the low bidder can actually perform.

What if a contractor fails prequalification?

Ask why. Many reviewers will approve a firm for smaller work, or with conditions, once the issue is explained or fixed.
