Prepare contractor quotations with measurable scope, material allowances, exclusions and change controls.
Measure the work
List locations, dimensions, quantities, specifications and who supplies each item. Separate labour, materials, equipment and provisional allowances. Attach drawings or a scope schedule where a single description would be ambiguous.
Price uncertainty honestly
Identify assumptions about access, working hours, permits, utilities and site condition. Explain how variations are priced and approved. Do not bury an open-ended exclusion that makes the headline total meaningless.
Set the project controls
Include programme, payment milestones, retention if applicable, warranty, validity and acceptance. Confirm insurance, safety and licensing requirements with the appropriate professional or authority.
Frequently asked questions
What is a provisional sum?
It is an allowance for work or materials that cannot yet be priced precisely; define how it will be adjusted.
Should contractors request a deposit?
That is a commercial and contractual decision. State the amount, trigger and treatment clearly.
