Start with the decision
Compare insulation proposals against the same scope and revision before comparing their totals. Pay particular attention to air barriers, vapour-control layers, firestopping, supports and closing finishes. The lowest number may describe a smaller package, and a more expensive offer may include work the other bidders have excluded.

Level the scope before the price
| Package | Difference to check | Evidence to request |
|---|---|---|
| Envelope insulation | insulation versus membrane and closure work | A written confirmation covering assembly schedule and location boundaries |
| Mechanical insulation | fittings, equipment and finish-covering inclusions | A written confirmation covering system list and referenced insulation specification |
| Interfaces | sealing, firestopping and adjacent-trade responsibilities | A written confirmation covering penetration and junction information |

Fill in the response, owner or source, and date checked. Keep unresolved items visible. The file contains planning prompts only; it does not calculate quantities or make an approval decision.
Put the checklist to work
- Create a column for each proposal and a row for each required deliverable. Use not stated when the proposal is silent.
- Separate firm scope from allowances and options. Request the basis of any provisional quantity rather than inserting your own assumed price.
- Check schedule assumptions against approved assembly information, preceding services and access before enclosure. Compare like-for-like access and timing as well as materials and labour.
- Ask each bidder to incorporate agreed clarifications into a revised proposal. Keep the revision and date alongside the comparison.
A scope gap worth discussing
Illustrative example — not a Build Accord client project
A wall insulation quote excludes the membrane included in another proposal. Confirm the assembly responsibilities so the wall package can be compared consistently.
Apply this to your decision: A comparison that explains scope and timing differences, plus a short clarification list. It is a decision aid, not an authorization to start work.
Using this in the US and Canada
For a project in the United States
Record the state, local jurisdiction and actual service area. Confirm the project location and the scope of the business’s authority with the responsible project team. The U.S. Small Business Administration provides a starting point for business licensing resources.
For a project in Canada
Record the province or territory, municipality and actual service area. Use Canada’s permits and licences resources to locate relevant checks, including the linked BizPaL service. Confirm requirements for the actual activity and location.
For either market, state the currency, units and deadline time zone. This worksheet is general planning guidance, not a determination of licensing, procurement eligibility or technical compliance.
The next useful step
Continue with insulation contractor schedule and lead-time checklist. For the other side of the conversation, see the insulation bid proposal guide.
Build Accord coordinates introductions between construction project teams and trade contractors. An inquiry starts a discussion of fit and availability; it does not guarantee a contractor, an invitation to bid or an award. These guides are not a listing of currently available crews or projects.
