Construction bid management: the complete guide for general contractors

For a general contractor, bid management is everything that happens between receiving a set of drawings and awarding the last trade package. It covers who you invite, what you send them, how you track their responses, how you compare what comes back and how you record the decision.

Most teams run it on email and a tracking spreadsheet. That works until a job has thirty trades, a tight bid day and two estimators who each hold part of the story in their own inbox.

The five stages of a bid

1. 1Invite: choose the subcontractors and suppliers you want pricing from.
2. 2Package: assemble drawings, specs, scope notes and the due date.
3. 3Track: see who has received the package, asked questions and responded.
4. 4Level: make the quotes comparable on scope, not just on price.
5. 5Award: pick, document and hand the trade over to buyout.

A bid list is only as good as the subcontractors on it. Aim for enough coverage in each trade that one no-show does not leave you without a number, but not so many that bid week turns into answering questions from vendors who will never win.

Four questions to ask before you invite

Try to collect three or more comparable bids on major trades where the market allows. On small or specialty trades, one or two credible quotes may be all that exists, and that is fine as long as you know it.

Most unhelpful quotes trace back to an unclear package. A good package answers the questions a subcontractor would otherwise email you about.

• The drawing and spec sections for their trade, at the current revision.
• A trade-specific scope sheet that says what is in and what is out.
• The bid due date and time, and how to submit.
• Schedule, site access and phasing notes.
• Insurance and bonding requirements.
• A contact for questions, and the date questions close.

Send addenda the same way you sent the original package and record who received them. A quote built on a superseded drawing is a common source of post-award change orders.

Subcontractors are busy. Many will quote only after a reminder, and some will not quote unless asked twice. The goal is a consistent rhythm that does not depend on one person remembering to send the nudge.

A follow-up rhythm that works

1. 1When the package goes out, confirm that it was received.
2. 2Midway to the due date, remind everyone who has not responded.
3. 3The day before, call the trades that matter most to your number.
4. 4After the deadline, decide quickly whether to extend or move on.

Keep a note of who declined and why. It makes the next bid list better.

Bid leveling is how you turn three different quotes into three comparable ones. A bid that looks lowest may simply leave out something the others included, and that difference comes back later as a change order.

How to level a trade

1. 1Start from your own scope sheet, not from the subcontractor's proposal.
2. 2Mark each line item as included, excluded or unclear for every bidder.
3. 3Put a price on every excluded or unclear item, from your own estimate or a follow-up question.
4. 4Add those amounts to each bid to get a leveled total.
5. 5Compare leveled totals, then weigh schedule, experience and risk.

Try it below. Click a status to change it, edit an amount, and watch the leveled totals move.

Awarding is where a good process pays off or falls apart. The record you leave behind matters as much as the choice you make.

• Write down why you chose the bidder, including the leveled numbers.
• Confirm scope in writing before the contract goes out.
• Send the subcontract for signature and keep the signed copy with the bid record.
• Collect the insurance certificate before work starts.
• Tell unsuccessful bidders promptly. It protects the relationship for the next job.

When the same project record holds the bids, the contract and later the billing, the handoff from estimating to operations stops being a data re-entry job.
