Questions to ask before construction begins

Prepare a brief with the location, intended use, scope, priorities, and available drawings or surveys. Ask each bidder to state inclusions, exclusions, allowances, and assumptions. Read our planning and budget guide for a comparison checklist.

Use the same scope and specification for each proposal. Compare quantities, finishes, site preparation, temporary works, approvals, disposal, and handover requirements. A lower total may omit work included by another bidder; request written clarification before deciding.

Existing drawings may not match what is on site. A suitable survey can help identify dimensions, condition, services, and access constraints. Structural changes or suspected defects require review by an appropriately qualified specialist.

It depends on the work and whether safe access, essential services, and separation from work areas can be maintained. Discuss dust, noise, service interruptions, security, and emergency access before agreeing a sequence. Some work may require temporary relocation.

Consider moisture, heat, sunlight, traffic, cleaning, repairability, and availability of replacements. Ask for manufacturer information and samples where appropriate. Our materials guide explains the trade-offs.

Requirements depend on the location, building use, and scope. Confirm the applicable process with the local authority and the project professionals before starting. Do not assume that internal work or a small extension is automatically exempt.

Record the proposed change, why it is needed, and its effect on scope, cost, and timing. Agree the authorised instruction in writing before work proceeds where practical. Keep the revised information with the project records.

Request a list of outstanding items, applicable inspection records, operating instructions, product information, warranties where provided, and maintenance guidance. Confirm responsibility for follow-up work and how completion will be recorded.
