Start with one brief
Give each contractor the same drawings, covered area, site information and finish expectations. Identify whether the quote covers grey structure, finishing or complete construction.
Check inclusions line by line
Request material specifications, quantities or measurement rules, labour scope and exclusions. Discuss temporary utilities, transport, external works and professional services separately.
Agree changes and payments
Ask how variations will be priced and approved. Link payments to written milestones and clarify how completed work will be reviewed.
Plan the reporting
Agree your site contact, progress reporting format and inspection points. Ask for an example report and keep decisions in a shared project record.
Keep your decisions together.
Ask for the same drawings, material specification and exclusions when comparing quotations.
