SUB-SURFACE

A misplaced shovel, avoided.

Every buried service — gas, water, electric, fibre, sewer, asbestos-in-ground — on the same register. Linked to a Permit-to-Dig workflow where the pre-excavation checklist gates approval. Six items must be ticked before anyone can dig.

HSWA 1974 duty of care to disclose buried services.

PERMIT

Permit-to-Dig with checklist gate

Anyone in the company can raise a permit. Only admins / managers can approve. And nobody can approve until six checklist items are ticked — drawings reviewed, utilities contacted, CAT scan, hand-dig zone marked, asbestos screen, isolation plan.

  • Six-item pre-excavation checklist
  • Hard server-side gate — UI lies, server enforces
  • Auto-incrementing PTD reference
  • Approver + approver-timestamp captured
  • Contractor link via the Contractors register

Asbestos-in-ground records

Control of Asbestos Regulations 2012 obligations don't stop at the building. Buried fragments — flue pipes, AC drains, infill — are tracked as a service type with their own depth and notes. The pre-dig checklist requires an explicit asbestos-screen tick.

  • Asbestos-in-ground as a service type
  • Asbestos-screen checklist item required
  • Linked Phase 2 environmental reports
  • Cross-reference to Site Risks add-on for site-wide picture

Sub-surface services — questions

No. The API enforces the gate server-side. Even a manager can't approve a permit with an incomplete checklist.
