Acceptance checks
- Re-run the reading for the hot tub after dark at In the tub after installation and confirm the controlling failure is not worse than the forecast for this proposal.
- Check the completed geometry against the decision record before accepting substitutions: width 8 ft 2 in, geometry note two canopies.
- Confirm the installed intervention keeps the forecast annual behaviour (seasonal).
- Photograph the completed work from the original reading point and record any change to view, glare, privacy line or usable hours that the model did not predict.
Questions every bid should answer
- What exact product, fixing/anchoring method and maintenance regime is included in the price?
- Which dimensions or assumptions in this record would your proposal change, and why?
- What is excluded from the price: structural design, footing design, drainage, electrical work, planning/permit work, boundary verification or underground-service locating?
