The eight steps
- Intake. Log the invitation on one bid board with GC, due date and time zone, RFI deadline, scope sections, bid form, documents link and job-walk date. Many invitations arrive through BuildingConnected, ConstructConnect, PlanHub or direct GC portals; put them all in one list.
- Bid/no-bid. Score fit (building type, tonnage, connection complexity), shop and erector capacity in the delivery window, the GC's payment history, competition and contract risk. Decide within a day. Our bid/no-bid guide for fabricators has a scoring sheet.
- Validate the set. Check the sheet index against what you downloaded, revision dates, scales, schedules and spec sections (05 12 00, 05 21 00, 05 31 00, 05 50 00). Find the connection design option, coatings, AESS designations and inspection responsibilities on day one, because those drive quotes you have to request early.
- Split the takeoff. Structural frame, frame attachments, misc. metals, stairs and rails, purchased items. Use the same columns every time: sheet, location, shape, length, count, connection type, finish.
- Request quotes. Material (mill or service center), joists and deck, galvanizing or special coatings, detailing, delegated connection engineering, erection. Send each supplier the same drawing list and your quantities.
- Review. A second estimator reviews by exception: biggest lines, ratios against history, every RFI and every exclusion.
- Handle addenda. Log each addendum, compare revised sheets to takeoff rows, reprice only what changed, and record the delta.
- Proposal. Scope letter with document list, inclusions, exclusions, qualifications, alternates, unit prices, validity and escalation terms.
What to standardize
- Folder structure: drawings, specs, addenda, RFIs, quotes and takeoff in the same place on every bid.
- Takeoff format: fixed columns so anyone on the team can review anyone's work.
- Exclusions library: standard exclusions you edit per job, such as field touch-up of galvanizing, fireproofing, embeds set by others, survey, special inspection, delegated design of stairs.
- Quote request template: same information to every supplier, with a reply-by date at least two working days before bid day.
- Bid board: one list with status for every opportunity, including no-bids and why.
Decide early. The cheapest way to speed up bidding is to stop spending estimator days on bids you will not win or do not want. A one-day bid/no-bid decision saves more hours than any tool.
Where the time goes, and fixes
| Step | Time sink | Fix |
|---|---|---|
| Takeoff | Finding and counting members across sheets | Fixed sequence, extraction tools, estimator review |
| Misc. metals | Items on architectural and MEP sheets | Full-set search, item checklist |
| Quotes | Chasing and leveling | Standard requests, early reply-by dates |
| Addenda | Re-checking everything | Compare revised sheets to takeoff rows |
| Proposal | Rewriting exclusions | Exclusions library |
Example: a ten-working-day bid
Illustrative schedule; adjust to your bid window
| Day | Work |
|---|---|
| 1 | Bid/no-bid, document log, sheet index check, spec read for cost drivers |
| 2–4 | Member takeoff by area and type; first RFIs out well before the RFI deadline |
| 4 | Joist, deck, coating, detailing and erection quote requests out with quantities |
| 5–6 | Connections, frame attachments, misc. metals, stairs and rails |
| 7 | Pricing: material, shop hours, erection plan and crane, freight |
| 8 | Internal review: big lines, ratios, scope letter, exclusions |
| 9 | Addenda and RFI answers repriced; supplier quotes leveled |
| 10 | Final number, proposal out, scope letter sent ahead of the GC's bid-day deadline |
Price validity and escalation
Steel prices move faster than many bid-to-award cycles. A construction-law presentation hosted by FCIA cites ABC's analysis of BLS producer price data showing steel mill products up 75.6% between May 2020 and May 2021. The lesson for the proposal: state how long the price is good for, what it is based on, and what happens if award or release is delayed.
- Validity: a short, explicit period, with the right to reprice after it.
- Basis: the mill or service-center quote date your material price reflects.
- Escalation: an adjustment clause tied to a published index, a baseline date and a threshold. ConsensusDocs 200.1 is a standard form for time- and price-impacted materials that some GCs and owners will accept.
- Flow-down: check that your purchase orders and the GC's subcontract say the same thing. The contract controls, not your proposal, once you sign.
Handoffs that slow bids down
- Material pricing: request quotes as soon as tonnage by shape is known, not after the takeoff is "done."
- Detailer and erector quotes: send drawing lists, piece counts and your erection assumptions early; erectors want a piece count before they will quote.
- Late addenda: keep the takeoff organized by sheet and area so deltas are quick to find.
- GC bid-day timing: many GCs want subcontractor numbers hours before their own deadline, and scope letters earlier still. Ask.
Standard outputs on every bid
- Member list by shape with weights, pieces and connection counts.
- Misc. metals and purchased-item lists.
- Scope letter with document list and addenda acknowledged.
- Assumptions and RFI log.
- Bid recap: what you bid, at what margin, who won, at what number if you learn it.
Measure where your time goes
Track estimator hours per bid by step for a few months. Most shops find takeoff and addenda repricing take the largest share, which tells you where a process change or tool helps most and gives you a baseline to judge it. Faster bidding should move estimator time from extraction to judgment, not cut review. RenderDraw's AI takeoff proposes members and quantities with the source sheet and flags uncertain items for review; you can benchmark it against one of your recent bids with a free sample takeoff.
