Survey standing: Quick: The sun can be placed. Angles, sunrise and sunset, and the shape of the day are right, and everything that depends on what stands in the way is a guess.

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
- What the paving actually is. Photograph the paving next to something white. How dark it is decides both how hot it gets underfoot and how much light it throws back up at a seated person.The overall verdict does not move, but wetness changes by 25 points, so it matters for that question specifically. · photograph
Acceptance checks
- Re-run the reading for dinner outside at Dinner 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: bearing 180°.
- Confirm the installed intervention preserves the tested 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
- Still unanswered: privacy exposure, 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?
Explicit exclusions and professional boundaries
This decision record is design intent and decision evidence, not a construction drawing, structural calculation, permit set, boundary survey or setting-out document.
This 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.
