Supervisor Chamber Audit Checklist

This supervisor-led checklist supports completed chamber audits for fiber network civil works. It guides teams to confirm street works permits and signage or SLG, verify calibrated gas detectors and correct lifting equipment before entry, and conduct gas tests. Inspect chamber construction on a concrete base, floated cement floor with sump and grate where required, and the correct number of sections. Check that duct entries meet spacing rules, are not in top or bottom sections, and are cut flush and sealed with silicone. Assess cover and frame installation on a mortar bed, level tolerance within +/- 6 mm, snug fit with no trip hazards, tarmac trimmed back, and a 150 mm concrete surround. Raise defects and assign actions as needed, then sign and submit.
