Put the decision into the scope
Build the conversion schedule and work sequence around dependencies: verified dimensions, material availability, demolition, concealed-condition review, plumbing, waterproofing, finishes and final checks. State when the enclosure can be measured and fitted. Distinguish site attendance from the date the assembly can actually be used.
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.
What schedule detail should be in the proposal?
Milestones, prerequisites and the process for communicating changes. A promised work period is difficult to assess if it excludes fabrication, waiting for materials or the manufacturer's required readiness conditions.
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.
