Describe the work
Share the general project type, location, approximate size and timing. You do not need a finished brief to ask which information would be useful next.
Confirm the assessment
Ask whether an on-site visit, drawings or other information are needed before a proposal. The contractor can explain its actual assessment process and availability.
Review the complete scope
Understand preparation, materials, access, removal, exclusions and the proposed sequence. Confirm who handles permissions and any specialist design before agreeing to proceed.
