How to Bid Construction Jobs When the Client Decides on Paper
There is a bid I have seen a dozen versions of. Eleven pages, saved out of a word processor as a PDF and emailed at 9:40 on a Friday night. Page one is a logo, a date, and the homeowner's last name spelled right this time. Page two is a column of figures with nothing beside them to say what they are. Page four says "allowances" without saying which ones. The last page has a signature line and no expiry, so the number can be quoted back to the builder next April.
The builder who sent it is good. Thirty years in, referrals for days, a crew that shows up. None of that is in the eleven pages. And the person deciding is often not the one who did the site walk with him.
That is the whole problem with how to bid construction jobs, and it is not a pricing problem. Most of the advice on bidding is about getting the number right. The number matters. It is also about half of the work.
Two halves: the number and the document
A bid has to do two jobs. It has to be right, so you don't lose money building it. And it has to be readable by someone who was not there, so you win the work in the first place.
This summer we ran 785 US general contractors through the same checks. 95.8% show no client-facing proposal system or portal on their public website. The whole study is posted here. What that means at the kitchen table is that nineteen bids in twenty arrive looking roughly the same, and the twentieth wins by default. I am going to walk the number half quickly, because you already know it, and spend the time on the half nobody teaches.
Qualify before you price
Before a single line of take-off, three questions.
Can you win it. Not "could you build it." Are you the right size for the job, is the schedule real, is the drawing set complete enough to price. If two of those are no, the bid is unpaid work with a low chance of turning into paid work.
Do you want it. Every builder has a job type he loses money on and keeps bidding anyway.
Who decides. This one gets skipped every time. On a custom home there are usually two people, and one of them met you. The other never set foot on the lot and will read your bid the way she reads anything: on paper, next to two others, with no voice in her head explaining it. Write the bid for her. The person who met you will forgive a thin document. She will not.
Do the take-off yourself
Do the take-off yourself, from the drawings, every time. Not from the architect's cost matrix, not from the last similar job, not from a square-foot number you carry in your head.
The reason is not pride. Somebody else's number already carries somebody's contingency. Put your fee and your own contingency on top and you have stacked two safety margins, and the total lands above the figure the owners were already carrying in their heads. You look expensive for a reason that has nothing to do with your price. I have seen a good builder lose a job on exactly that arithmetic.
Your own take-off is also the only version you can defend in the room. When the client asks why framing is what it is, "that's what the drawings measure" is an answer. "That's what the estimate said" is not.
The number, its range, and what is not in it
Give the number an honest range and say what would move it toward each end. A single figure on a preliminary estimate reads as a promise. A range with reasons reads as competence.
Then say what is not carried. Site work beyond the footprint. Rock. Utility upgrades the town might require. Whatever is a real unknown on this lot gets a sentence. The builders who get burned on change orders are usually the ones who never wrote down what the number excluded.
Allowances get stated as allowances, with the figure, and with a line that says what happens above it. Tile, fixtures, appliances, lighting. A homeowner who picks a $14,000 range after being allowed $6,000 should have seen that coming on page five of your bid, in plain words.
Schedule and expiry
A start date, a duration, the three or four milestones that matter to a homeowner: weathertight, rough inspections, drywall, punch. Not a Gantt chart. A paragraph.
And an expiry. Material prices move, your calendar fills, the sub who quoted you retires. A preliminary estimate should say plainly that it is good for thirty days, or sixty, and then it is a conversation again.
While we are on that page: a preliminary estimate with a signature line on it is an offer. The first document in a good sequence is the one nobody signs. It holds the scope, a figure with a range around it, the exclusions, and the open questions that decide where in the range it lands. The signature comes later, on a letter of intent, with a retainer attached. The four-document sequence lives at /bid-room/documents, and the preliminary estimate has its own page at /bid-room/estimate.
Now the half nobody teaches: how it goes out
Everything above is the number. Here is how it reaches the second reader.
A link on your domain, not an attachment. An attachment gets filed. A page on your domain with her house on it gets opened twice. No single change matters more. 95.8% of the field has not made it.
One rendering off the drawings they gave you. The sheets become a 3D study, measured, from one camera position, and the page says it is a study rather than passing it off as a finished home. A cabinet shop will draw up a $9,000 kitchen in 3D, free, to win the order. In August's Meta Ad Library, not one of the 26 top custom-builder ads brought up 3D. The rendering's job inside a bid has a post of its own.
The estimate that looks like it came from you. Your numbers, your take-off, set into a page that reads as your company rather than a spreadsheet dump.
The pages in order. Letter, render, scope in plain words, exclusions, allowances, the figure, the calendar, the terms, and what gets signed next. The construction proposal template, page by page walks each one. The order is most of the work.
Follow-up already running. Before the link leaves your hands, know what you will do on day one, day three, and the day it goes quiet after the price page. Send a link with nothing behind it and by Thursday you are the one calling, and it feels like selling.
A 70-site audit by Contractor Growth Network put homeowners at 32 seconds on a generic process page against 3 minutes 55 seconds on a page that shows real renderings and talks about real pricing. Same buyer. The difference is whether there is anything on the page to read.
What it looked like on real jobs
Custom Crafted Homes, a Cape Cod builder I work with, second-generation builders and family-owned since 1974, sent five proposals through a setup built this way. Four closed. Among them, a $1.1M home won off the rendered proposal, which sits inside the ~$1.4M that closed through their CRM rather than added to it. The boundary rides along: the systems were built here; the company closed the sales. Craft, reputation, and the handshake at the site walk were all theirs. The system's part was showing that second reader the house before she saw a figure.
The full ledger, boundary included, lives at the proof page.
The order I would do it in
- Qualify. Three questions before any take-off.
- Take-off from the drawings. Yours, every time.
- A figure, a range, the exclusions, allowances as allowances.
- Schedule as a paragraph. Expiry on the page.
- One render from their plans, labeled honestly.
- Pages in order, on your domain, as a link.
- Follow-up planned before it goes out.
- The next document ready, so a yes has somewhere to go.
Steps one through four are yours and always will be. Steps five through eight are production work, and production work is what the owner never has time for on a Tuesday night, which is why it doesn't happen. The Bid Room is that production, done per bid. Drawing and numbers go in; five business days once intake is complete, the package is live, or it's free. The fee tracks contract size and is printed before work starts, from $299 when the job is under $100K up to $5,000 for a $1M–$5M custom home. Or pay $0 up front and five percent at signing. How long a bid should take covers the five days.
If the bid is the last thing the client sees before deciding, the site is usually the first. The marketing plan for a construction company puts the two in order for a season.
