Verification queue
- The maple height. Measure how tall the maple actually is. A pole and a phone photo is enough.The overall verdict does not move, but direct sun changes by 86 points, so it matters for that question specifically. · measure
Acceptance checks
- Re-run the reading for dinner outside at The dining table after installation and confirm the controlling failure is not worse than the tested proposal.
- Check the completed geometry against the decision record before accepting substitutions: height 7.1 ft, width 8.1 ft, distance from reading point 10.7 ft, bearing 162°.
- Confirm the installed intervention preserves the tested 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
- How will you verify: A confirmed observer?
- How will you verify: Somewhere on your own land to stand it?
- Measure the actual height available before ordering: this is sized at 2.2 metres and a hundred millimetres either way changes whether it works.?
- Mark 3.3 metres out on the ground and stand there before committing. The geometry is only as good as that distance.?
- Still unanswered: noise.?
- 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?
