Drywall and framing bid sheet: how subcontractors build a bid

A bid sheet is the page where quantities become a price. The structure is simple. The discipline is in filling every line, writing down what you assumed and not forgetting what is outside your scope. This post walks through the usual sections of a drywall and framing bid sheet. It uses no dollar figures on purpose, since your costs and rates are your own.

1. Start with a clean takeoff

Everything on the sheet traces back to the takeoff, so errors there flow through the entire bid. Group quantities by wall type and note which sheets you counted. If you need a process, see the construction takeoff guide. If wall types are unclear, see reading a wall type legend. For a large repeating project, the apartment building walkthrough shows how to organize it.

2. Convert quantities to materials

For each wall type, convert footage and area into a material list: board by sheet and thickness, studs by size, gauge and spacing, track, insulation, fasteners, tape and compound, corner bead, trim, sealant and any specialty items the spec calls out. The guides on drywall sheets and metal studs show the math, and the calculators let you check it. Keep rated and non-rated board on separate lines, as covered in types of drywall.

3. Apply waste

Add a waste allowance per material, because cuts, openings, damage and offcuts are real. Use factors you have tracked from your own jobs and supplier advice. Different materials waste differently, so one blanket percentage hides errors. Show the net quantity, the waste and the order quantity in separate columns so a reviewer can see each.

4. Material pricing

Get current quotes from your supplier and note the date and validity period. Prices change, and a quote that expires before award is a risk. Note delivery, stocking to floors, restocking terms and any minimums. Record the quote number on the sheet so you can trace it later.

5. Labor

Labor comes from production rates applied to installed quantities: hanging, framing, taping and finishing, each with its own rate. Your own historical hours per quantity are the best source. Adjust for conditions: ceiling height, access, phasing, winter conditions, finish level, repeating layouts that speed work and tight spaces that slow it. Include supervision, layout, cleanup, mobilization and punch-list time. Those are easy to forget because they have no quantity.

6. Equipment and other direct costs

Lifts, scaffolding or stilts, dumpsters, temporary protection, tools and consumables, travel and per-diem, permits or bonds if required. Mark each as included, owner-furnished or excluded.

7. Overhead and markup

After direct costs, add your overhead (office, vehicles, insurance, software, admin) and your profit. How you calculate and apply these is a business decision that depends on your company's cost structure and market. The key point for the bid sheet is to keep them visible as separate lines instead of burying them inside unit rates. That makes it easier to adjust a bid on purpose during negotiation, instead of by accident. Also account for taxes, bond or insurance costs the contract requires.

8. Alternates, allowances and unit prices

Read the bid form. If the GC asks for alternates, add-alternates or unit prices for extra work, price them in the format requested. Ambiguous qualification on a required line can get a bid thrown out.

9. Exclusions and clarifications

This section protects your margin. State what your price includes and what it does not. Common items to address:

• Which sheets, addenda and spec sections the bid is based on, by number and date.
• Finish level for drywall, and whether paint or primer is included.
• Rated assemblies and what testing, inspections or firestopping you do or do not provide.
• Blocking, backing, and who installs it.
• Ceilings, soffits, bulkheads, shaft walls and exterior sheathing, in or out.
• Hazardous material, demolition, patching of existing conditions.
• Schedule assumptions, phasing, overtime, off-hours work.
• Wall types where the legend was missing, unclear or conflicting, and the assumption you used.

10. Bid-day checklist

1. Confirm every addendum is received and acknowledged, and your quantities reflect the latest revision.
2. Re-check the takeoff for double-counted sheets and missed floors.
3. Check the wall-type grouping against the legend, including rated walls.
4. Verify supplier quotes are current and cover all line items.
5. Confirm labor assumptions and the schedule duration.
6. Review overhead and markup lines and any required bond or insurance costs.
7. Read the bid form and instructions again: format, alternates, due time, delivery method, required forms.
8. Have someone other than the estimator scan the sheet for obvious errors such as a dropped floor or a misplaced decimal.
9. Submit early enough to handle technical trouble, and save a copy of exactly what was sent.

Where bids come from

Subcontractors generally find work through a few categories: direct invitations from general contractors you already work with; plan rooms and bid-management services, many of them local or regional; public bid sites run by cities, counties, school districts and state agencies, which post notices of upcoming projects; and industry associations and networking. Each source has different rules for access, so check the terms. The mix that works varies by region and project type.

Where software fits

The takeoff step is where software helps most. ReadMyBlueprint measures walls from vector PDFs, groups them by wall type, labels each result so you can see what needs confirming, and exports the results as a CSV you can use in your own bid sheet. See the confidence labels for how results are flagged. The rest of the sheet, from pricing to markup to exclusions, remains your judgment, and you verify every bid before it goes out.

Common questions

What goes on a drywall bid sheet?

Quantities by wall type, material lists with waste, material pricing, labor, equipment and other direct costs, overhead and markup, alternates, and a written list of exclusions and clarifications.

How do I add waste to a drywall estimate?

Apply a waste allowance per material, based on your own tracked jobs and supplier advice, and show net quantity, waste and order quantity separately.

What should a drywall bid exclude?

Anything not in your scope or not clear from the drawings: items such as paint, blocking, hazardous material, rated-assembly testing, overtime work and wall types you had to assume. List the sheets and addenda your price is based on.

Where do drywall subcontractors find bids?

Common sources are invitations from general contractors, plan rooms and bid-management services, public bid sites run by government agencies and industry networking. Access rules vary by source.
