A real model, live on this page
One of the models Build built from a plan set. Drag to turn it, the way a GC turns one from the link in a proposal, with no account and nothing to install.
Research
Build, by its own records.
Build is one shared 3D model for the whole project team. Here is the record: the model links sent and opened, the bids sent, the dollars proposed and what came of them, drawn from Build’s own records. The two companies sending bids are Company A and Company B. No client or job is named, and no bid is tied to a GC.

One shared 3D model
The whole project team on one model, and how it spreads
Build puts every company on a job on one 3D model: the GC, every trade, the detailers and the vendors. Today the model stops with the architects and engineers; Build carries it past them, simple enough for a sub or a GC to open from a link with no account. It starts at the bid, where a sub builds the model to price the job, and it spreads from there.

How we count: Each company counts once, in the week Build first sent it something (a model, a proposal, a price request or a detailing ask), and once more in the week it first opened one. Opens leave out the sending company’s own team and link scanners.
52 GCs that opened a 3D model sent from Build
The GCs in Build’s public directory that opened a model link, with their logos and towns as the directory lists them. No job, date or bid is tied to any of them.

How we count: Opening a model doesn’t mean a company uses or endorses Build. Companies on bids held back for client confidentiality are left out, and so are the companies that opened one but aren’t in the directory.
How Build spreads
Every way in is live, and every one starts from a paying company’s own work. The quoted lines are the words Build sends.
- 1. Live, the most used
The 3D model share link
“Company A shared a 3D model”
The GC opens it from the proposal with no account, and the page’s one button is “Join the project team.” 91 of the 99 companies that got one opened it.
- 2. Live since October 21
The Building
“Company A invited you to the Building”
The model, drawings, RFIs and changes for the job in one place, for every company on it to see and work on with the team. 22 invites so far.
- 3. Live
The company invite
“Not on Build? Invite them by email”
A sub looks up its GC, detailer or vendor. If they aren’t on Build, one line asks them to join, and they land on what was already sent to them.
- 4. Live
Every send carries Build
Proposals, price requests and detailing asks
Each goes out from Build with its way back in. 175 companies have had one.
- 5. Live
The crew poster
“Join Company A on Build”
The field crew joins from a QR code with a phone number and a texted code, in English and Spanish.
- 6. How the business grows
Paying companies pull their jobs in
Free for everyone but the bidder
The GC, the other trades and the vendors on a paying company’s jobs open, join and work on Build free. The ones that bid become the next paying companies.
How we count: One count per link and company it went to; a company counts once however many links it got. Opens leave out the sending company’s own team, the addresses it opens from, and link scanners. Bids held back for client confidentiality are left out. Counted at 10:07 AM PT, Oct 31.
Growing

How we count: One count per job, in the week its first proposal went out. Resends and the same bid to more GCs aren’t counted again, so 221 send records become 161 jobs. Bids held back for client confidentiality are left off every count.
Dollars proposed, running total
$49.2M across the 161 jobs. The dashed end is the week so far.

Impact
What it does for an estimator, and what came of the bids
Every bid in Build is built up from the cost, so each one shows its gross margin and net profit to everyone at the company who works it. Trades usually bid on a flat markup percentage or a gut-check price per foot, and see what a job made only after it’s over. The GC sees the proposal, never the margin.
Gross margin and net profit on every bid
Every bid Company A and Company B sent at 30% gross margin or lower was won. A company that sees its margin on every bid can see where it wins.
How a trade usually prices
A flat markup percentage, or a gut-check price per foot or per square foot. What the job made shows up after it’s over.
On Build
Built up from the cost, with the gross margin and net profit on the bid for everyone at the company who works it, before it goes out.
4 of 4bids sent at 30% gross margin or lower were won
0lost
0still open
How we count: A bid counts when it went out with its gross margin on record at or below 30%: the margin on the version sent, else the last priced version before the send. Wins are the deals marked won. Only the count is shown; no bid’s margin is. Bids held back for client confidentiality are left out.
One estimator’s desk on Build, against 198 estimator-months without it
Gray bars count the months by how many bids an estimator sent, in other steel companies’ records, Dec 2022 to Jul 2026. The blue marks are Company A’s months on Build.

How we count: Without Build: deals with a bid date in those companies’ records, per estimator per month. The median month is 5 bids; 3 in 4 months are 9 or fewer, 9 in 10 are 17 or fewer, and the most is 44. With Build: Company A’s jobs first sent each month.
What one bid costs to run
Six full bid runs measured from their usage cost $44.85 to $67.38. Against the median bid of $115,244, that is about 0.05%.
Table
| Full bid run | Usage |
|---|---|
| Run 1 | $44.85 |
| Run 2 | $55.49 |
| Run 3 | $60.44 |
| Run 4 | $61.63 |
| Run 5 | $64.50 |
| Run 6 | $67.38 |
How we count: Usage dollars at Build’s published rate card, from each run’s receipt: the takeoff, the 3D model, the price and the proposal.
What happened to the bids
140 of the 161 jobs have a deal record. 12 were won, 13 were lost, and 105 worth $38.4M are still open.
Table
| Where the bid stands | Bids | Deal value |
|---|---|---|
| Won or handed to the shop | 12 | $2,219,724 |
| Closing | 5 | $813,171 |
| Likely | 44 | $15,957,001 |
| Waiting on the GC | 56 | $21,649,962 |
| Unlikely | 8 | $5,676,131 |
| Lost | 13 | $5,755,254 |
| Inactive | 2 | $40,382 |
How we count: A win counts only when it came after the bid went out. Dollars are the deal values on record, which can differ from the proposal total.

Verifiably real
How anyone can check it
Nobody should have to take a chart on faith. These make every number on this page checkable, and none of them shows a client’s name.
Read live from the database
The page reads Build’s database at most once an hour and prints the time it read it. Nobody types a number into the page.
How we count, under every chart
The definition in plain words and the table behind each chart, on the page itself.
A receipt for each sent proposal
One row per sent proposal: the date, the company letter, a size band, what happened, and the first 16 characters of the PDF’s SHA-256 fingerprint.
Check a PDF yourself
Drop a proposal PDF on the page. The browser fingerprints it on your own computer, never uploads it, and lights up its row.
A public record each night
Every night the receipt list, with each PDF’s full fingerprint, is copied to a public repository whose history anyone can read. A receipt can’t be added later with an earlier date without it showing there.

Each Monday Build freezes that week’s numbers. Last frozen Oct 26.
What the 221 send records carry
Since Sep 28, 89 of 107 sends were recorded the day they went; the rest, and every send before then, were filed from the sent mail. The receipts mark which is which.

The receipts: 185 sent proposal PDFs with a fingerprint on record (the same file sent to two GCs appears twice). Bids held back for client confidentiality are left out. Size bands: under $25K, $25K–$100K, $100K–$250K, $250K–$1M, $1M and up.
Said out loud
What the numbers don’t say
Saying it first is what makes the rest believable.
- Two companies send bids from Build today, and one estimator’s desk estimates for both. The first company from outside was priced in October and hasn’t paid. Revenue so far is $0.
- Before Sep 28, bids were filed into Build from the sent mail after they went out. Since then, 89 of 107 sends were recorded the day they went. The receipts mark which is which.
- The model links, the opens and the companies reached are measured. How many of those companies go on to pay is still ahead.
- Most assistant calls and agent changes are the companies’ own agents working these bids. They show the product doing the work. They are not outside adoption.
- The estimator comparison is one estimator’s desk with Build against nine estimators’ records without it. It isn’t a controlled study. The records without Build end in July 2026.
- 12 of the 25 decided bids were won, and 105 are still open. It is too early to quote a win rate.
- Bids held back for client confidentiality are left off every count, chart and receipt.
- The current week is always partial, and every chart draws it lighter.
- The 30% line rests on four bids. It shows where these bids won, not a rule for every job.
