Construction bid proposal letter template
A bid letter that a GC or owner can read in a minute and level in five. The template gives you every block in order with bracketed wording: offer, drawings and spec sections, addenda, inclusions, exclusions, alternates, unit prices, qualifications, validity and acceptance.
- Offer and documents
- Inclusions and exclusions
- Alternates and unit prices
- Validity and acceptance
Defines exactly what you are pricing
A construction bid letter, or bid proposal letter, is the subcontractor's or contractor's formal offer: a price for a defined scope based on specific documents. Its job is to remove ambiguity. The offer names the documents by date and spec section. The addenda line proves you priced the current set. Inclusions and exclusions say what is and is not in the number. Alternates and unit prices give the buyer options. Qualifications state the assumptions. Validity limits how long the price holds.

How to use it

The offer block
"[Company] proposes to furnish labor, materials and equipment for [trade/scope] per drawings dated [date] and specification sections [list], for the lump sum of $[amount]." That sentence carries most of the legal weight of the letter: scope, documents and price. Fill each bracket carefully.
- Addenda. "This proposal includes Addenda [numbers]."
- Inclusions and exclusions. Short bullet lists, in plain language.
- Alternates. "Alternate [#]: [description], add/deduct $[amount]."
- Unit prices. "[Item]: $[price] per [unit]."
- Qualifications. Schedule, access, working hours, material escalation.
- Validity. "This proposal is valid for [n] days from the date above."
Use both when asked
Many GCs and public owners require their own bid form. Fill it exactly as instructed, and attach your letter for inclusions, exclusions and qualifications only if the instructions allow attachments.
RenderDraw's AI takeoff proposes quantities with sources for estimator review, and approved quantities hand off to your pricing and visual CPQ.
Spend your hours on scope and price, not re-counting.
RenderDraw's AI takeoff reads drawings, schedules and specs, proposes quantities with the source sheet attached, and holds uncertain items for estimator review before anything is priced.
- Source on every quantity. Each count, length and area keeps its source sheet and location.
- Lowest confidence first. The review queue puts the items most likely to be wrong at the top.
- Addenda through the same review. Send the changed sheets through takeoff and estimator review, then reprice what moved.
- Approval before pricing. Nothing moves on to pricing until an estimator accepts it.
Send one plan set
Pick a real job with an addendum. Sample files stay private while RenderDraw assesses the request, and there is no obligation to proceed.
RenderDraw does not publish accuracy percentages or time-saved claims. Test it on your own plan set.
Questions estimators ask.
What should a construction bid letter include?
The offer (scope, documents and price), addenda acknowledged, inclusions, exclusions, alternates, unit prices, qualifications, validity and an acceptance or signature block.
Is the bid letter template free?
Yes. Download the XLSX or CSV with the wording blocks.
Should I list exclusions in a bid letter?
Yes, explicitly and near the top. Hidden exclusions cause disputes and lost trust.
How long should a bid be valid?
State a period appropriate for your market and material price risk. Many contractors use 30 to 90 days, but set your own.
