Water damage prevention checklist for construction projects

Water-related incidents can severely impact construction project schedules, increase costs, compromise safety and affect long-term building performance. This checklist is designed to assist contractors, property owners and project team identify common water risks, assign responsibilities and take steps to help prevent, detect and respond to water damage events.

 


Roles, responsibilities and planning

Focus areaRecommended actionYesNo
Project oversightAssign responsibility for water damage prevention, mitigation and response  
PlanningMaintain a water intrusion response plan, valve isolation schedule and isolation map.  
Documentation

Review project documents, QA/QC procedures and builders risk policy requirements.
  
Contractor coordination

Confirm subcontractor responsibilities through scope, submittal and prequalification reviews.
  
Daily controls

Provide project-specific procedures and maintain daily oversight.
  


Risk identification and controls

Focus areaRecommended actionYesNo
Temporary water sources and distribution

Use approved piping and hoses for temporary water systems, and routinely inspect connections, fittings and valves.

 

 

 

Inclement weather and flooding

Maintain drainage, flood protection and operational sump pumps with backup power as needed.

  
Building envelope protectionProtect openings from water intrusion, verify envelope performance through testing and ensure exterior surfaces drain away from doors.  
Inspecting and protection porous building materialsIdentify moisture-sensitive materials, store them properly and inspect after water or humidity exposure.  
Vandalism and unauthorized access

Secure the site, restrict access to water systems and mechanical spaces and document any tampering or damage.

  



Valve isolation and automated controls

Focus areaRecommended actionYesNo
Valve isolation maps

Maintain current valve isolation maps showing valve locations and IDs, post them in key areas and clearly label isolation valves.

  
Automated and monitored shutoff devices

Install automatic water shutoff devices where feasible, use approved monitoring and alert systems and establish response procedures for alarms.

  



Quality control and inspection criteria

Focus areaRecommended actionYesNo
Documented inspections

Inspect, verify and document piping system readiness before activation.

  
Craftsmanship and installation controls

Ensure approved materials, qualified installation practices, and proper management of piping connections.

  

 

Procedures for charging piping systems

Focus areaRecommended actionYesNo
Pre-charge checklistVerify approvals, communication and readiness before charging.  
Charging protocolCharge systems gradually under supervision and during normal working hours. This is going to go longer.  

 


Leak detection and early warning

Recommended actionYesNo
Conduct daily walkthroughs of active water systems.  
Place moisture sensors in high-risk areas, such as mechanical rooms, vertical shafts and areas below active piping.  

Use moisture sensors in areas with high-value or long-lead-time finishes.
  

Keep temporary floor drains clear and operational.
  

Report and respond immediately to any leak, regardless of size.
  
Review available water flow and leak detection technology resources from Hanover Risk Solutions.  



Prompt response and mitigation plan

Focus areaRecommended actionYesNo
Maintain state of emergency readiness

Ensure response plans, resources and personnel are ready.

  

Immediate actions

Stop water, contain damage and protect the site.  
Mitigation and recovery

Dry, mitigate and document affected areas.

  
Reporting and root cause analysis

Report incidents, determine root causes and implement corrective actions.

  


Training and compliance

Focus areaRecommended actionYesNo
Personnel training

Train all site personnel on the leak reporting process and the location of main shutoff valves.

  
Guide integration

Incorporate this guide into site orientation and review during safety meetings.

  
Compliance follow-upAddress non-compliance through corrective action
