Public bid invitations are the trailing edge of a process that's mostly already played out. By the time a project hits a public plan room or a bid board, the GC shortlist has been narrowed, the architect has had two or three preferred-vendor conversations, and the developer has decided more or less who's going to be invited to bid.
The leading edge — the signals that tell you a project is about to bid — is what determines whether you get on the invite list in the first place. Those signals are public, traceable, and earlier than most contractors think. Here are seven of them, ordered roughly from earliest to most-immediate.
Signal 1: Plat preliminary approval
When a plat lands on the Planning Commission's preliminary approval agenda, the project is about 240 days from a building permit on the median commercial project. The developer is real, the land is real, and the project is past speculative diligence. I wrote a longer piece on how to read Harris County plat filings, but the short version: this is the earliest publicly visible signal worth acting on. The contractor who reaches out within 30 days of preliminary approval is almost always the first GC the developer talks to.
Signal 2: New LLC formed at the project's mailing address
Cross-reference the parcel ownership on a recently transferred property with the Texas Secretary of State filings. An LLC formed within 18 months of acquiring the parcel is almost always a development entity. The LLC's purpose is the project. The LLC's principals are the decision-makers.
An older LLC that owns the parcel is also interesting but lower-signal — it's often a holding company with a longer time horizon. A new LLC is much more directly tied to a near-term construction project. The ratio of "new LLC owner" to "actual construction in 24 months" in Houston is about 70/30 — much higher than any other ownership-side signal.
Signal 3: Plan review submission with a named architect
Once the plat is approved, the next public event in the lifecycle is the plan review submission. This is where the architect of record gets named on the public record. The presence of an architect — and which architect — is high-signal.
Some architects have known GC partners they always recommend. Some don't. If the architect on the plan-review submission has a history of recommending specific GCs, the GC shortlist is half-formed before the submission was made. If the architect is one of the firms that runs an open invitation process, you have a real opportunity.
Signal 4: Site work permit before BLDG
Some commercial projects pull a separate site work permit — for clearing, grading, utilities — before the main building permit. Site work permits are issued faster (the review is shallower) and they signal that the developer is committed enough to spend $40K–$200K on site prep.
From site work permit issuance to building permit issuance is usually 60–120 days. If you see a site work permit on a parcel that doesn't yet have a building permit, you have a tight, predictable window before bid pursuit gets crowded.
Signal 5: Variance or special exception filing
Variances and special exceptions — for setbacks, height, lot coverage — get filed when the project doesn't fit cleanly within current zoning. They're public, they go through the Board of Adjustment, and they're rarely tracked by lead-list products.
What makes them high-signal: a variance filing means the developer has invested in design enough to know what the project will require, and they're committed enough to spend the time and legal fees to push it through. About 85% of approved variances in Houston convert to a permit within 24 months. Far higher than the baseline for plat filings.
Signal 6: Architect or engineer hires a permit expediter
This is the most insider of the seven. There are about a dozen permit expediters in Houston who handle most of the active commercial work. They get named on the application even when the architect is the one running the project. When a known expediter shows up on a parcel where they haven't been before — and especially when the parcel just transferred or got plat approval — there's a real project moving.
Why this matters: expediters get hired about 30–60 days before plan review submission. By the time the permit shows up publicly, the expediter's name has often been on the file for two months. This is one of the few signals that's earlier than the plan review itself.
Signal 7: The owner's LLC just added a manager
Track the Texas Secretary of State filings on known development LLCs. When an LLC adds a manager — particularly one whose name is associated with construction management or development — the project is staffing up. This often happens 90–180 days before construction starts.
This signal is the most labor-intensive to monitor manually. You need to maintain a watch list of LLCs and re-pull SOS filings on a cadence. But it's also the most predictive late-stage signal — by the time a new manager is added, the project is committed.
The honest counterpoint
None of these seven signals are perfect. About 25–35% of the time, a signal fires and nothing happens — the LLC dissolves, the financing falls through, the project shrinks, the parcel sits. That's the baseline noise of public-records signal.
What works is not relying on any single signal. The contractors who use this kind of intelligence well are running pursuit against a portfolio of 40–80 active projects at any given time, each one with two or three signals stacked. The portfolio averages out the noise. A single project with three signals firing is much more likely to bid than a single project with one signal.
Doing this kind of monitoring by hand is roughly a 15-hour-per-week job for one analyst. If you've already given up on lead lists, this is the workflow that replaces them — and it's the workflow Platineer automates.
