Read-only demonstration. Four sanitised or hypothetical engineering projects. Each states its own validation status; nothing shown is engineer approved.

CALCULATIONS AND SCHEDULES

Calculations, schedules and BOQ

The current calculation package, equipment Required / Offered schedules and BOQ, with each run's own calculation workbook and schedules — by topic, with revision, source, native evidence status, previews and downloads.

P07 PROPOSED — not checked or approved by an engineer, not for construction

Checked by / approved by: NOT RECORDED — no verified engineer identity; nothing here is engineer approved or issued for construction.

PROPOSED — not checked or approved by an engineer, not for construction. Workbooks holding licensed CIBSE Guide C data stay local (named, with the reason); their review pages and every other workbook download here with their SHA-256.
