How Does a Subcontractor Get on a GC's Bid List?

Most general contractors keep a list of subcontractors by trade and region. When a job comes in, the estimator invites the subs on that trade's list whose size and location fit, often several per trade, and needs enough of them to bid that the package is covered. Before a sub goes on the list, many GCs prequalify it: a questionnaire on experience, backlog, finances, bonding, insurance and safety, turned into a limit on the size of job you will be invited to.

What a GC weighs usually mirrors the federal test of a responsible contractor: adequate financial resources, the ability to meet the schedule "taking into consideration all existing commercial and governmental business commitments", a satisfactory performance record, integrity, the organization, experience and technical skills, and the equipment, or the ability to obtain them (FAR 9.104-1). Your packet should answer each before it is asked.

If you are a small business, large federal prime contractors have a written reason to find you. Other-than-small primes on federal contracts expected to exceed $900,000 ($2 million for construction) with subcontracting possibilities must submit a small business subcontracting plan (FAR 19.702). The plan describes the efforts the prime will make to ensure small businesses "have an equitable opportunity to compete for subcontracts", and the records it keeps, including source lists (FAR 19.704). Ask those primes' small business liaisons how to get on their source lists.

On the safety line: an employer that keeps the OSHA 300 Log must create and certify an annual summary each year, with the annual average number of employees and the total hours worked, and post it from February 1 to April 30 (29 CFR 1904.32). A prequalification form that asks for your safety record is usually asking for that summary. The paperwork collected after you win a job (W-9, certificate naming the project, lien waivers) is a separate step; see the documents a GC requires from a sub.

Everything on it can be checked, and the size range matches the bonding: a $1,200,000 job is inside a $1,500,000 single-job limit. A GC with a $3,000,000 glazing package knows not to invite Ridgeway yet; one with a $400,000 package knows to.

1. List the GCs that build your kind of work in your area. Public bid results and plan rooms show who bids what.
2. Find the estimating or preconstruction contact. Ask the receptionist for whoever invites your trade.
3. Send the capability sheet with a two-line note: your trade, your size range, and that you would like to be invited.
4. Ask for their prequalification form and return it complete within a week. A half-filled form reads as a half-run company.
5. A few weeks later, check that you are on the list and ask what work they have coming that fits.
6. Bid the first invitation you receive, on time, in their format, even if the job is not your best fit. The first bid is the audition.

• Answer every invitation. If you are passing, decline quickly and say why; an estimator counting coverage needs to know.
• Bid in the GC's format, priced against its scope items, with exclusions stated plainly. How to write a sub proposal a GC can level shows how.
• Acknowledge every addendum and ask questions before the deadline, in writing.
• Ask how your bid compared after award; the answer tells you whether your pricing is close.
• Update your capability sheet and bonding letter once a year.

Once you are invited, how to bid a GC's job as a subcontractor takes it from there, and the subcontractor's guide covers the rest of the job.

Getting on a bid list is a short, checkable packet sent to the right person: a capability sheet, a project list, a bonding letter, an insurance certificate and a safety record, followed by a complete prequalification form.

Staying on it is about bid-day behavior: answer every invitation, bid on time in the GC's format, and decline quickly when you pass.
