Construction Proposal Template
The structure of a construction proposal or bid — scope of work, materials and labour, schedule, exclusions, change-order terms, payment schedule and warranty. The exclusions and change-order sections are where construction proposals are won and lost.
A construction proposal is the bid a contractor gives a client for a defined piece of work. It differs from most proposals in how much rests on the boundary: the scope of work, the exclusions and the change-order terms are what determine whether the job is profitable, because they decide who pays when the site reveals something the drawings did not. A strong one defines the work precisely, separates materials from labour, sets a schedule with weather and access assumptions, lists exclusions explicitly, states how changes are priced and approved, and ties payment to milestones. The eight sections below cover it.
What a construction proposal includes
Eight sections. Sections three and six — exclusions and change orders — matter more here than in any other kind of proposal.
Construction proposal template: a filled example
The eight sections above are the template; this is a short bid written into them, so the precision the sections ask for is visible rather than described. A small residential job, condensed to the lines that decide whether it is profitable.
| Section | Filled in |
|---|---|
| Scope of work | Supply and install a single-storey rear addition, 14ft by 12ft, to drawing A-104 revision C dated 12 May: footings, framing, roof, one set of bifold doors, and drywall finished ready for paint. |
| Materials | All materials supplied by us except the bifold doors and the floor finish, which carry allowances of $4,200 and $1,800. A selection above its allowance is a variation, priced at the difference plus 15 per cent. |
| Labour and crew | A crew of three for weeks one to four. Roofing and glazing are subcontracted to named trades and their prices are carried in this bid rather than billed on later. |
| Exclusions | Permits and inspection fees, asbestos or contaminated-ground handling, tree-root or drain diversions, any work outside the addition footprint, redecoration beyond making good, and out-of-hours working. |
| Schedule and access assumptions | Eight working weeks from a start no later than 1 September. Assumes access 07:30 to 17:00 Monday to Friday, a working outside tap and power, a dumpster standing on the driveway, and no more than five days lost to weather. |
| Change orders | No work outside the scope above proceeds without a written variation signed by the client. Variations are priced at $520 a day for the crew plus materials at cost plus 15 per cent. |
| Payment schedule | 15 per cent on acceptance, 25 per cent when the footings inspection passes, 25 per cent when the structure is dried in, 25 per cent at drywall complete, 10 per cent at substantial completion. Every stage is triggered by something observable on site, not by a date. |
| Warranty, insurance and terms | Two-year workmanship warranty; manufacturer warranties on the doors and the roof membrane passed through. General liability and builder's risk held, certificates on request. This price stands for 30 days from the date above. |
The figures, dimensions and dates belong to a made-up job and exist to show the grain, not to be reused. Arc drafts this structure from your own scope notes and cost inputs; it does not price the work or give legal or contractual advice.
What wins and what loses
| What wins | What loses |
|---|---|
| Prices against a named drawing revision | Prices against 'the plans' with no revision |
| Explicit exclusions, including ground conditions | Exclusions implied by an inclusions list |
| Allowances stated with an amount | Unpriced selections left to be resolved later |
| Change-order mechanism agreed up front | Variations handled by conversation on site |
| Stage payments tied to observable milestones | Payments tied to calendar dates |
| A stated validity period on the price | An open-ended price while material costs move |
How Gixo Arc drafts this
Arc builds this structure from your own scope notes and cost inputs, and the answer library reuses the exclusions, change-order and warranty language you have already approved — which is exactly the text that should not be rewritten from scratch per bid, because a wording change in an exclusions list is a commercial change. Arc does not price the work or provide legal or contractual advice; the numbers and terms are yours to set and review.
Construction proposal template: FAQ
What should a construction proposal always exclude?
At minimum: permits and fees unless stated, waste disposal beyond what is named, unforeseen ground or structural conditions, hazardous material handling, and work outside the defined area. Each of these is a common source of unpriced work.
How do I handle client selections that are not made yet?
Carry an allowance with a stated amount and say what it assumes. When the selection is made, the difference is a visible variation rather than a disagreement about what the price included.
Should a construction proposal include a payment schedule?
Yes, tied to observable milestones rather than dates. Milestone-based staging protects both sides when the schedule moves, which on most sites it does.
How long should a construction bid stay valid?
State it explicitly — 30 days is common where material prices are moving. An open-ended bid transfers all material price risk to you for as long as the client takes to decide.
What should a construction proposal template include?
Eight sections: the scope of work referenced to a named drawing revision, materials with any allowances stated, labour and the trades you are subcontracting, an explicit exclusions list, the schedule with its access and weather assumptions, the change-order mechanism, a payment schedule tied to observable milestones, and warranty, insurance and price validity. The outline and the worked bid on this page are that template in full.
Is there a free construction proposal template?
The eight-section outline and the worked bid on this page are free to copy into your own document — there is nothing to download and no signup. Generating a tailored proposal from your own scope notes and cost inputs is the paid Arc workflow; the structure itself is not the paid part.
