How to read a bid tabulation (and what it tells you about the next one)

The results are public. Reading them properly is how you stop guessing at your own margin.

When a public job is bid, the prices go on the record. Most bidders glance at the tabulation to see whether they won and never look again. That is a waste, because the tabulation is the only honest feedback you will ever get about your own numbers — and it is free.

What a tabulation is

A table of every bidder and their price, usually with the engineer's or architect's estimate, and often with unit prices and alternates. It may be published as "unofficial" pending review, and the award notice is the final record. Both are worth keeping, but only one is authoritative.

Read the spread, not just the winner

The gap between first and last tells you how contested the job was. A tight cluster near the estimate means the market priced it the same way you did. A wide scatter means somebody misread the scope, or priced a risk nobody else saw, or was desperate. Both are information: the tight cluster tells you your estimate was sound, and the scatter tells you the job was unclear.

Unit prices are where strategy shows

When unit prices are published, they reveal how a low bidder got low. A bid that is cheap on the quantities that will shrink and expensive on the ones that will grow is unbalanced on purpose — it wins the bid and earns its margin on the changes. That is legal in many places and it is also a warning: if you are competing against it with a balanced price, you will lose the bid and the job may still cost the owner more.

Look too at the alternates. A bidder who is low on the base and high on every alternate is betting the alternates get taken, or that they do not.

Who keeps winning, and why

Read three or four tabulations from the same buyer and a pattern appears. One firm is consistently low on a certain kind of job, another is always second. That is either a genuine cost advantage — their yard is closer, their crew is faster, their overhead is lower — or a pricing habit that will eventually catch them. Either way, it tells you where not to spend your effort and where a small improvement would actually move you from third to first.

The most useful number is your own delta

Keep your own record: what you bid, what won, and by how much you missed. After a dozen jobs you will find the pattern in your own pricing — consistently a few percent high on one kind of scope, or consistently winning the jobs you were least sure about. That is far more useful than any general advice about margins, because it is about your numbers, not somebody else's.

Two cautions. Results published before award can be corrected, so do not rewrite your pricing strategy on the strength of an unofficial tab. And a tabulation tells you what people bid, not what the job cost — the winner may have lost money, and that is not a benchmark you want.

Where to find them

Most public buyers publish tabulations on the same page as the solicitation, or in the board packet for the meeting where the award is approved. School districts and cities often put the award on a council or board agenda, which is the most reliable place to find both the recommendation and the reason. If you cannot find it, ask the buyer — the same conversation usually gets you both.
