Most contractors asking where to find jobs to bid on are really asking a different question: why am I losing the ones I bid? Bidding more of the same work rarely fixes that. The sources below are ordered by when the opportunity reaches you, because that single variable does more to determine your win rate than anything you do to the number.
The seven sources, ordered by timing
| Source | When you hear about it | Competition | Cost |
|---|---|---|---|
| Past clients & referrals | Before anyone | None | Free |
| Owner / developer relationships | Pre-design | Very low | Time |
| Plat & subdivision filings | Months before build | Very low | Free (public) |
| Permit & plan-review filings | Weeks–months before start | Low | Free (public) |
| GC invitation lists | At bid time | Invited bidders only | Free |
| Plan rooms / bid boards | At bid time | Every subscriber | $50–$300+/mo |
| Public bid portals | At bid time | Everyone | Free |
1. Public bid portals (government work)
Every public body that spends money on construction is required to advertise it. Cities, counties, school districts, transit authorities, universities and state agencies each run their own vendor portal, and registering is free. In Texas that means the city's purchasing portal, the county, the ISDs, and the state's central system.
The upside is that the work is real, funded and transparently awarded. The downside is structural: the solicitation reaches every registered vendor at the same instant, the scope is fixed before you see it, and award is often lowest-responsible-bid. You are competing purely on number. Public work is worth having in the mix — it is not a strategy on its own.
2. Plan rooms and bid boards
Subscription plan rooms aggregate solicitations and invitations into one feed with notifications and document access. For a sub chasing a high volume of bids across a wide area, that convenience is genuinely worth money.
Be clear about what you are buying, though. A plan room sells aggregation, not exclusivity — every other subscriber gets the same posting at the same time. It compresses your admin, it does not improve your position. If a board's pitch is that it will get you more work, ask when its listings appear relative to the permit filing for the same project.
3. General contractor invitation lists
For subs, this is the single highest-value list to be on. Being an invited bidder means a smaller field, a GC who already believes you can do the work, and a scope conversation rather than a price contest.
- 01 ·Identify the GCs who actually build your project type in your area — not the biggest names, the ones whose work matches your scope and size.
- 02 ·Find the estimator or preconstruction lead by name. Invitations come from a person, not a company.
- 03 ·Send prequalification material before you ask for anything: licence, insurance, bonding capacity, three relevant references.
- 04 ·Respond to every invitation, including the ones you decline — a fast, clear no keeps you on the list; silence removes you.
4. Permit and plan-review filings
This is where the timing advantage lives, and it is the source most contractors never systematically use. Before a project is built it is permitted, and before it is permitted the drawings go through plan review. Those filings are public records, and they name the address, the scope, the declared valuation and — critically — the owner and the applicant.
A permit application is not an advertisement for bids. That is exactly why it is useful: at the moment it appears, most of the trades on that job have not been selected. You are making contact while the bid list is still being written rather than after it has closed.
5. Plat and subdivision filings
Earlier still. A plat is the legal division of land into lots, and it is filed with a planning commission before anything vertical is designed, let alone permitted. A subdivision plat is the earliest public signal that a piece of ground is going to become houses, and a commercial replat often precedes a large development by a year or more.
Plat filings will not give you a scope to price. What they give you is a name — the developer or engineering firm behind the application — and a lead time long enough to build a relationship before a bid list exists. For sitework, utilities, concrete and framing, that is the most valuable list in the market.
6. Owners and developers directly
The people who repeatedly commission construction — developers, property managers, facilities directors, franchise operators — are a small, knowable group in any market. A developer who filed three plats last year will file more this year. Repeat buyers are worth tracking as buyers, not as one-off projects.
Permit records make this measurable rather than anecdotal: the same owner entities and applicants recur across filings, and the volume tells you who is actually building versus who is merely visible.
7. Past clients and referrals
The cheapest work you will ever win, and the most commonly neglected. A GC or owner who has already paid you has no acquisition cost, no prequalification friction and no price contest. A scheduled quarterly call to every past client outperforms most bid-board subscriptions, and costs nothing.
A practical weekly routine
- 01Monday — check what filed last week
Review new permit and plan-review filings in your zip codes, filtered to your trade and job size. You are looking for projects that are committed but have not bought out your scope yet.
- 02Monday — check new plats
Scan plat and replat filings for subdivisions and commercial sites in your area. Note the developer and engineer names; these are relationship targets, not immediate bids.
- 03Tuesday — make contact
Call the applicant or owner on the three or four best filings. You are not bidding; you are asking who is handling the trades and offering to be on the list.
- 04Wednesday — work the invitations
Answer every GC invitation, including declines. Keep prequalification packets current so a request never stalls you.
- 05Friday — maintain the relationships
Two calls to past clients, one to a developer you have identified from plat activity. This is the pipeline that pays in six months.
Frequently asked
- Do I need a licence to bid?
- Texas has no statewide general contractor licence, but electrical, plumbing and HVAC are licensed at state level, and municipalities impose their own registration requirements. Public and commercial work will also require insurance certificates and often bonding capacity.
- How many jobs should I bid to win one?
- It depends entirely on source. Open public bidding commonly runs in the 5–10% range; invited private bidding is far higher; negotiated work sourced from an early relationship is higher still. Track your rate per source rather than overall — the average hides the thing you need to know.
- What is a bid bond?
- A surety instrument guaranteeing that if you are awarded the contract you will enter into it at your bid price. Most public work and larger private work requires one, which means establishing a bonding relationship before you can bid that tier.
