The slab that is too hot in July and too slow to dry in November

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

The modelled change, whether it has been tried at the place, 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.

A 6 ft 11 in panel to the south-west

weak across seasons

A solid panel about 6 feet 11 inches high and 9 feet 10 inches wide, standing 7 feet 3 inches to the south-west. Low sun arrives almost horizontally, and only something vertical stops it.

Survey standing: Mapped: Shade, sky view and daily light are computed from the geometry on this plan. Unmeasured dimensions remain estimates, not verified measurements.

Real-world trial: none yet. Everything above is a forecast from the plan.

Verification queue

  1. 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
  2. What you are looking at. Mark the direction of the view worth keeping. No view has been marked yet, so nothing weighs what the view is worth, and a screen that blocks it looks free.

Acceptance checks

  • Re-run the reading for crossing barefoot at Barefoot crossing 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 6 ft 11 in, width 9 ft 10 in, distance from reading point 7 ft 3 in, bearing 240°.
  • 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

  1. How will you verify: The hour the complaint is actually about?
  2. Measure the actual height available before ordering: this is sized at 6 feet 11 inches and about four inches either way changes whether it works.
  3. Mark 7 feet 3 inches out on the ground and stand there before committing. The geometry is only as good as that distance.
  4. What exact product, fixing/anchoring method and maintenance regime is included in the price?
  5. Which dimensions or assumptions in this record would your proposal change, and why?
  6. 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

CheckA tall panel in an exposed place is a sail, and it needs footings sized for it.
CheckIt blocks the view in that direction too, which is often the direction the view is in.
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.
