Verification queue
- Who can actually see in. Sit where you actually sit and look around. Mark the one window or path you can see a person from. Until one exists, privacy is a question we are not answering rather than one that is fine.This is not a refinement. Nothing can answer this question until somebody marks it. · sit-there
Acceptance checks
- Re-run the reading for morning coffee at The morning chair 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: height 26 ft, distance from reading point 16 ft 5 in, bearing 245°.
- Confirm the installed intervention keeps the forecast annual behaviour (weak).
- 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: Root room clear of the house and services?
- How will you verify: Mature spread that fits?
- Measure the actual height available before ordering: this is sized at 26 feet and about four inches either way changes whether it works.
- Mark 16 feet 5 inches out on the ground and stand there before committing. The geometry is only as good as that distance.
- Try the reversible version first, even badly. A week with a borrowed umbrella tells you more than a drawing.
- Still unanswered: privacy exposure.
- 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?
Explicit exclusions and professional boundaries
CheckMature size, root behaviour near foundations and drains, and local suitability are questions for a nursery or arborist who can see the site.
CheckModelled at maturity. Nothing about this helps for the first several summers.
CheckThis decision record is design intent and decision evidence, not a construction drawing, structural calculation, permit set, boundary survey or setting-out document.
CheckThis record does not determine wind or snow loading, foundation or footing geometry, attachment adequacy, drainage works, electrical compliance, buried-service clearance, property lines or required approvals. Those questions remain with qualified people who can inspect the site and selected product.
