Roof work above occupied premises: coordinating users and contractors

An agreed roofing start time is insufficient if another team or a delivery is scheduled in the same place. Conflicts need to be identified jointly before individuals begin their tasks.

Mark rooms and circulation routes beneath the proposed works on the building plan. Add their operating hours and a person familiar with current movements. The contractor should not have to infer room use from the façade. Identify locations accessible to customers or people outside the technical team in particular.

Compare roof work with other planned activities, including brief service visits. Separately identify installations that may affect the work, such as automatically starting equipment. Their status and any isolation must be agreed by people authorised for the installation. Telling a team that “nobody normally goes there” is insufficient.

Determine exclusion areas from the work method and its possible effects on surroundings. Do not limit them to the visible repair patch or a convenient position for tape. If the required separation conflicts with building use, change the arrangements or suspend the affected activity. Scheduling does not replace physical protective measures.

For each closed area, assign responsibility for access control and informing users of changes. Agree how a first-time visitor will be handled instead of assuming everyone knows the arrangements. Signs should support the protective system, not serve as the only protection from falling objects or entry into a hazardous area.

Review tool access, material delivery and waste removal routes separately. Each may cross an entrance, loading bay or pedestrian route at a different time. Record agreed time windows and building contacts. Where transport requires movement restrictions, confirm those restrictions are effectively in place before the load is moved.

Do not alter escape routes by leaving materials in them or closing convenient doors. The effect of the works on evacuation needs agreement with those responsible for users’ safety. If the proposed arrangements do not permit safe evacuation, do not continue normal operations merely because the job is expected to be brief.

At a shift change, hand over current closures, the work stage and unresolved hazards. Identify protections that remain in place and who may authorise changes. A morning agreement with one person does not brief the afternoon team. The recipient should confirm awareness of the current restrictions.

A subcontractor joining during the works needs the same current information as other teams. A start time and entrance number are not enough. Discuss the work area, scope boundaries and how new conflicts will be reported. Its task may require existing arrangements to be revised before shared access is used.

Agree a straightforward way to report unexpected events: people entering a closed zone, changed weather or an unrecorded opening being found. Stop the affected work when the agreed safety conditions no longer hold. Restart only after responsible people have assessed the situation and restored effective controls.

Coordinate emergency arrangements between contractor and manager, including actual access, contacts and how help is summoned. A building alarm does not replace rescue planning for work at height. Check that temporary closures do not obstruct the agreed response. Scenarios needing specialist techniques must be planned by competent people with suitable equipment.

At the end of a stage, confirm which areas can actually be handed back to users. Remove restrictions only after the agreed check, and show any remaining ones on the current plan. Inform the next shift and entrance staff. One team’s completion does not automatically remove hazards from the remaining works.
