Put the decision into the scope
Use a comparison sheet with one row each for removal, backing, base, drain, valve, waterproofing, finish, enclosure and restoration. Mark each item included, excluded or allowance. Normalize product selections before evaluating totals, then compare how each proposal handles unknown conditions and changes.
Before accepting a proposal
Check that the written proposal names the products, defines the demolition boundary and explains the connection to retained work. Identify any allowance or unresolved selection, and ask who coordinates the relevant trades. Agree how concealed conditions will be documented and how changes require authorization. A broad installation label leaves too much room for different assumptions about what the finished project includes.
How should an allowance be treated?
As an amount or scope still subject to its stated conditions, not a fully specified selection. Ask what it covers, what selection is assumed and how any difference is calculated and authorized.
The owner should confirm the proposed service scope and provider availability independently. This guidance does not identify an approved contractor, establish coverage for a specific property or guarantee acceptance of the project.
