A reliable programme is a sequence with dependencies, not a promised number of days. Surveys, approvals, bespoke manufacture, ground work, weather, inspections and specialist trades can each affect the critical path.

Typical project stages

1. Measured and condition survey.
2. Design, specification and quotation agreement.
3. Planning, building-control and other approvals where applicable.
4. Technical sign-off and product manufacture.
5. Site preparation, foundations and drainage.
6. Base, frame, roof, glazing and weathering.
7. Services and internal finishes.
8. Testing, inspection, snagging and correction.
9. Handover of certificates, guarantees and maintenance information.

Before work starts, ask which dates are fixed, estimated or conditional and who updates the programme after a delay.

FAQs

Which stages can be delayed by weather or approvals?

Ground work and weathering are exposed to conditions, while design and start dates may depend on authority decisions. The contract should handle both.

What should a snagging list record before final sign-off?

Record the location, issue, photograph, agreed remedy, owner and completion date. Separate incomplete contract work from optional changes.

Suggested component

A dependency-aware timeline and printable snagging list; no universal completion-date prediction.
