Verify before disturbing systems
Confirm drainage, utilities, structure, equipment and approvals before excavation or alteration.
Installation planning
Installation Guidance for Flood-Protection Systems
High-level practice guidance for organizing safe, verifiable and maintainable installation work without replacing trade instructions or project design.
- Risk-firstbefore product choice
- Evidencebefore claims
- Lifecycleinspection and maintenance
Who this is for
Use the guidance within a defined role and scope.
- Contractors and installers
- Inspectors and project managers
- Building owners
- Municipal programme teams
RSM scope
Independent education and standards-informed practice guidance.
External authority
Law, code, municipal rules, permits, manufacturer instructions and qualified professional decisions remain controlling.
Project responsibility
Owners, designers, contractors, inspectors and authorities retain assigned duties.
Core principles
Build practice around clear decisions and verifiable outcomes.
Use competent authorized people
Plumbing, electrical, excavation and engineering work must remain within lawful competence.
Respect product instructions
Approved equipment must be installed and commissioned according to applicable instructions.
Protect future access
Do not trade convenience for inaccessible valves, pumps, sensors or records.
Practice detail
Pre-installation planning
Define work boundaries, existing conditions, flooding pathway, design basis, permits, locates, occupants, shutdowns and contingencies. Confirm whether the work affects structure, electrical systems, sanitary or storm services, accessibility or public property.
Practice detail
Execution and hold points
Use hold points before cutting, connection, concealment, backfill and energization. Verify compatible materials, support, access, cleanouts, discharge, electrical approval, labelling and protection. Record field changes before they disappear.
Practice detail
Commissioning and handover
Demonstrate safe operation, alarms and backup where applicable, access and labels. Handover should include photos, product information, permits, inspections, limitations, maintenance instructions and emergency steps.
Working sequence
A repeatable pathway from question to maintained outcome
- 1
Confirm risk, scope and approvals.
- 2
Obtain locates and plan access.
- 3
Verify materials and competent roles.
- 4
Inspect before concealment.
- 5
Commission and complete handover.
Avoidable failures
Common ways good intentions become unreliable practice
- Excavating before locates
- Working around an unverified obstruction
- Concealing changes without records
- No maintenance instructions

What is a hold point?
A planned stage where work stops for verification before concealment, backfill or energization.
Who signs off the work?
That depends on the work, permit, contract, regulator and authority having jurisdiction.
