A second seat 19 ft 8 in south-east
Record demo-front-porch-street:1:second-seat:2026:10:30:17. Read on 30th October 2026.
Put two chairs 19 feet 8 inches to the south-east and leave the main table where it is. The point is not to fix this spot but to stop needing it at the hour it does not work.

Acceptance checks
- Re-run the reading for reading for an hour at The porch 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: distance from reading point 19 ft 8 in, bearing 154°.
- 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: Somewhere else on the property that behaves differently?
- Mark 19 feet 8 inches 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?
