Bid the current documents
Record the drawing issue, specifications, addenda, bid form, deadline, and alternates before takeoff begins. Document control is the first estimating control.

A reliable construction bid connects the issued documents to quantities, quantities to current costs, and costs to a qualified commercial offer. BuildVision AI assists the plan-takeoff and proposal path while the estimator remains responsible for scope, price, risk, and submission.
Working principles
Record the drawing issue, specifications, addenda, bid form, deadline, and alternates before takeoff begins. Document control is the first estimating control.
Use current supplier and subcontractor quotes, maintained labor, equipment, waste, overhead, markup, bonds, tax, and project-specific risk.
State inclusions, exclusions, allowances, unit prices, alternates, validity, schedule assumptions, and commercial terms so the number has a defined scope.
Decision guide
A bidding system should reduce duplicate work without concealing the assumptions that make a price defensible.
| Factor | What good looks like | How to verify it |
|---|---|---|
| Document intake | Keep sheets, specifications, addenda, deadlines, and trade scope together. | Run a bid with a late addendum and confirm the team can prove which issue was priced. |
| Takeoff evidence | Every material quantity should remain traceable to a plan mark, schedule, detail, or named allowance. | Ask a second estimator to audit several high-value quantities without verbal guidance. |
| Cost build-up | Separate quantities, unit costs, labor, equipment, subcontract, indirect cost, and markup. | Change one supplier quote and confirm the estimate updates predictably without overwriting history. |
| Proposal output | Produce a consistent offer with scope and qualifications, not only a grand total. | Compare the issued document with the approved estimate and check every alternate and exclusion. |
Practical sequence
Confirm documents, revisions, scope, deadline, alternates, and bid requirements.
Create the takeoff, verify evidence, and complete scope from notes and specifications.
Apply current rates, quotes, labor, waste, indirect cost, markup, and risk.
Issue the approved proposal with inclusions, exclusions, options, and terms.
Common questions
Estimating develops quantities and cost. Bidding turns that estimate into a commercial offer and may also manage invitations, deadlines, coverage, leveling, or submission. Some products connect both jobs.
It should not. AI can assist plan takeoff, but a responsible estimator must verify documents, scope, quantities, prices, labor, quotes, exclusions, risk, and the final offer.
Check addenda, bid form, quantities, quotes, labor, tax, bonds, allowances, alternates, exclusions, schedule assumptions, math, signatures, acknowledgements, and delivery instructions.
Verify current product capabilities, material systems, code requirements, commercial terms, and local pricing with the responsible vendor, designer, contractor, or authority.
