What is a bid score? Two answers, depending on which side of the table you sit
Contractors use "bid score" to mean the number they give an opportunity before deciding to bid it. Owners use it to mean the number they give your bid after you submit it. Both are weighted scoring grids, and both decide where the money goes. Here is how each one is built, with a worked example of each.
What is a bid score?
A bid score is a weighted number that summarises how attractive a bid is. For a contractor it is the go/no-go opportunity score, usually 0 to 100, assigned to a lead before estimating starts, built from criteria such as relationship, competition, margin and payment risk. For an owner it is the evaluation score assigned to each submitted bid in best-value procurement, built from price and technical criteria with published weights.
The two uses share a structure: pick criteria, give each a weight, rate each on a fixed scale, multiply and add. What differs is who is scoring whom and what the score decides. The contractor's bid score decides whether an invitation gets an estimate. The owner's bid score decides who gets the contract. If you have only met one of them, it is worth knowing the other, because the owner's grid is the reason your go/no-go grid should have a "scope fit" line in it.
Bid scoring for go/no-go: the contractor's bid opportunity score
Every shop that bids more than it can estimate needs a way to decide which invitations get the hours. Gut feel works until the pipeline outgrows one person's head, and then you get the classic pattern: bid everything, win 8%, burn the estimating department. A bid opportunity score replaces the gut with a short list of questions the whole shop agrees on, weighted by what each has cost you in the past.
A simple version uses seven criteria, weights that add to 100, and a 1 to 5 rating on each. The weighted score is the weight multiplied by the rating divided by 5, so a perfect 5 on a 20-point criterion contributes 20 and a 1 contributes 4. The total lands between 20 and 100.
| Criterion | Weight | What a 5 looks like | What a 1 looks like | Example rating | Weighted |
|---|---|---|---|---|---|
| Relationship with GC or owner | 20 | Repeat client, they called you | Cold invitation, never worked together | 4 | 16 |
| Competition | 15 | Two or three invited, you are known to be strong | Public open bid, ten or more numbers | 2 | 6 |
| Margin potential | 20 | Your specialty, pricing power, little levelling | Commodity scope, price is the only lever | 3 | 12 |
| Schedule and capacity fit | 15 | Starts when a crew frees up, sensible duration | Overlaps your two biggest jobs, compressed schedule | 5 | 15 |
| Payment risk | 15 | Known fast payer, retention released on time | Slow-pay history, disputes, unknown funding | 3 | 9 |
| Scope fit | 10 | Work you do every week, crews and gear on hand | Unfamiliar systems, would need to sub half of it | 4 | 8 |
| Strategic value | 5 | Opens a market, builds a reference | Nothing beyond this job | 2 | 2 |
| Total | 100 | 68 |
The example pursuit scores 68. What that means depends on the thresholds you set.
Thresholds: bid, bid selectively, no-bid
A score is useless without a decision rule attached to it. Three bands are enough for most shops:
- 70 and above: bid. Full estimate, full supplier coverage, best price you can hold.
- 50 to 69: bid selectively. Bid it if the estimating calendar is open and the backlog is thin, or bid it with a loaded markup that pays you for the risk lines that dragged the score down. If the pipeline is full, pass.
- Below 50: no-bid. Send the no-bid letter the same day, so the GC keeps inviting you and you keep the hours.
The 68 in the example is a selective bid, and the grid tells you why: competition is heavy and payment is uncertain. It says "bid this if we can add a few points of markup for the payment risk, and only if we have the hours", which the owner and the chief estimator can both read the same way.
Two refinements make the score honest. Hard-kill rules override the total: a pursuit whose peak receivable would exceed a set share of your working capital, or a client with an open payment dispute, is a no-bid whatever the other criteria say. And thresholds should follow backlog: six months booked, raise every band; six weeks, lower them for a quarter. The reasoning is in the bid/no-bid scoring model and the bid/no-bid checklist.
How the free scorecard computes a bid score
Our bid/no-bid scorecard is the same idea with the weights we have found matter most for subcontractors. It asks seven questions, each rated 0 to 3. Pay history, schedule fit and accounts-receivable exposure carry a 3x weight; personnel availability, scope clarity and retention terms carry 2x; competitive field carries 1x. The maximum weighted score is 63, and the default bands are 45 and above to bid, 32 to 44 to bid with loaded markup, 20 to 31 strategic only, and under 20 no-bid.
It then does what a spreadsheet grid usually skips. Hard-kill rules: peak AR above 40% of available working capital forces a no-bid whatever the score, a zero on pay history caps the verdict at strategic only, and AR between 20 and 40% of working capital caps it at bid with loaded markup. Backlog calibration tightens the bands at six months booked and loosens them at two. Under the verdict it shows the break-even hit rate, an estimated win probability and the expected value of bidding, so you can see whether the pursuit makes money on average before you open the plans.
The bid/no-bid Excel template has the same engine plus a cash-exposure model and a pursuit log. Either way, the score is only as good as the habit of filling it in before the takeoff, not after.
Bid scoring on the owner's side: best-value evaluation
Now the other meaning. In a low-bid procurement there is no scoring; the lowest responsive, responsible bid wins. In best-value procurement, common on public work above a certain size, design-build, and most private CM selections, the owner publishes an evaluation grid and every submitted bid gets a score. Price is one criterion among several, and the weights are in the RFP.
A typical grid gives price 50 to 70 points and splits the rest across technical criteria: past performance on similar projects, proposed team and key personnel, schedule and approach, safety record, and sometimes local participation or sustainability. Price points are usually awarded by formula, with the lowest price getting full marks and everyone else scored in proportion: your points = lowest price ÷ your price × price weight. Technical points come from a panel reading the proposals against a rubric.
| Criterion | Weight | Bidder A ($1,000,000, strong technical) | Bidder B ($950,000, weaker technical) |
|---|---|---|---|
| Price (lowest ÷ yours × 60) | 60 | 950,000 ÷ 1,000,000 × 60 = 57.0 | 60.0 |
| Past performance | 15 | 13.0 | 10.0 |
| Team and key personnel | 10 | 8.0 | 6.0 |
| Schedule and approach | 10 | 8.0 | 7.0 |
| Safety record | 5 | 3.0 | 3.0 |
| Total bid score | 100 | 89.0 | 86.0 |
Bidder A is $50,000 higher and wins, because the technical gap was worth more than the price gap under this grid. That is the point of best-value: the owner has written down the exchange rate between price and quality, and you can read it too. With a 60-point price weight, every 1% you are above the low bidder costs about 0.6 points; a stronger past-performance write-up can be worth 3 to 5. It also explains why your own go/no-go score should weigh scope fit heavily on best-value work: if the owner's grid gives 40 points to criteria you cannot score well on, the pursuit is a price competition, and your opportunity score should say so.
Using the two bid scores together
The practical loop: an invitation arrives, someone fills in the opportunity score in ten minutes before anyone opens the plans, and if it clears the threshold the estimate starts. On best-value work the estimator reads the owner's grid at the same time and decides how much of the bid budget goes into the technical proposal versus the number. The result goes into the pursuit log against the score, and after twenty or thirty bids the weights get adjusted to match what actually won.
This matters more now because the takeoff no longer has to be the bottleneck. When quantities come off the plans in minutes rather than a week, an estimator can run the full estimate on more of the pursuits that score well and put the recovered hours where the owner's grid rewards them. Pilars does the takeoff side, for $100 per trade per plan set; you can run it on your own set. The bid score tells you which sets are worth uploading.

Questions estimators actually ask
What is a bid score?
A weighted number that rates how attractive a bid is. For contractors it is the go/no-go opportunity score given to a lead before estimating, usually on a 0 to 100 scale. For owners it is the evaluation score given to a submitted bid in best-value procurement, combining price and technical criteria with published weights.
What is a bid opportunity score?
The score a contractor assigns to an invitation to bid, built from weighted criteria such as relationship, competition, margin potential, schedule fit, payment risk, scope fit and strategic value. It is used to decide whether the pursuit gets estimating hours, with thresholds for bid, bid selectively and no-bid.
How is bid scoring done in best-value procurement?
The owner publishes weights, commonly 50 to 70 points for price and the rest for technical criteria such as past performance, team, schedule and safety. Price points are awarded by formula, lowest price scoring full marks and others in proportion; technical points come from an evaluation panel. Highest total wins.
What is a good bid score for go/no-go?
In a 0 to 100 weighted grid, 70 and above is a clear bid, 50 to 69 is a selective bid depending on backlog and markup, and below 50 is a no-bid. Thresholds should tighten when backlog is full and loosen when it is thin, and hard-kill rules on payment risk should override the score.
What criteria go into a bid scoring matrix?
Most contractor grids use five to eight criteria: relationship, competition, margin potential, schedule and capacity fit, payment risk, scope fit and strategic value. Weights add to 100 and each criterion is rated on a fixed scale.
How does the Pilars bid/no-bid scorecard calculate a score?
It rates seven questions from 0 to 3, weighted 3x for pay history, schedule fit and AR exposure, 2x for personnel, scope clarity and retention, and 1x for competitive field, for a maximum of 63. Bands are 45+ bid, 32 to 44 bid with loaded markup, 20 to 31 strategic only, under 20 no-bid, with hard-kill rules and backlog calibration.
Is a bid score the same as a bid-hit ratio?
No. A bid score is assigned to a single pursuit before or after bidding. A bid-hit ratio is the share of submitted bids you won over a period, usually twelve months. A good scoring habit is the main lever for improving the ratio.
