The hot tub that feels like a stage

A decision record somebody can price without pretending it is a construction drawing.

The tested change, the geometry it depends on, the annual consequence, what must be verified before ordering, what success looks like, and the questions the bid still has to answer.

Survey standing: Mapped: Shade, sky view and daily light are computed from real geometry rather than assumed. This is the rung at which the product starts telling you things you did not already know.

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 tested proposal.
  • Check the completed geometry against the decision record before accepting substitutions: distance from reading point 6.6 ft, bearing 68°.
  • 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

  1. How will you verify: Somewhere else on the same surface to put it.?
  2. Mark 2 metres out on the ground and stand there before committing. The geometry is only as good as that distance.?
  3. What exact product, fixing/anchoring method and maintenance regime is included in the price?
  4. Which dimensions or assumptions in this record would your proposal change, and why?
  5. 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.
