Planning fire safety works in an occupied building

In an occupied building, the work area is also someone's home, workplace or route through the property. A technically sound fire protection proposal therefore needs an equally considered delivery plan. Access, resident communication, other trades and the condition left at the end of each working period all affect the programme.

This guide is aimed at housing and property teams preparing passive fire protection works in England. Whether a building or part of it can remain occupied during particular activities must be determined for that project by the responsible team and competent advisers.

Establish who makes the decisions

Before agreeing a start date, identify the client lead, the person responsible for the building's fire safety, the contractor's site lead and the resident liaison contact. Make clear who can authorise changes and who receives urgent concerns outside normal working hours.

Where multiple contractors are involved, coordination needs an appointed owner. A fire stopping team should not discover on arrival that a plumbing contractor still needs the opening it has been asked to close. Equally, a service contractor needs to know when later work would disturb completed fire protection.

HSE's commercial client guidance explains client responsibilities under the Construction (Design and Management) Regulations, including suitable project arrangements and the provision of relevant information. Establish which duties and appointments apply to the work before mobilisation.

Build the programme around the building's actual use

A floor-by-floor programme may look efficient on paper but fail when it meets resident appointments, care visits or essential services. Gather the operational constraints early and share the information relevant to each team.

Useful questions include:

• Which activities require entry to individual homes, and for how long?
• Which doors, routes or services are affected at each stage?
• Are there known communication or access needs that require agreed support?
• What work by other trades must happen before and after each task?
• Who checks and records the condition left before the team departs?
• What happens if access fails or an unexpected condition is found?

Do not assume that a task being brief makes it suitable to carry out without a coordinated plan. Our resident access and appointments guide helps clients prepare a clear appointment process.

Communicate what residents need to know

Use a general explanation of the programme, followed by specific appointment information. Explain the purpose of the visit, who will attend, how identification can be checked, what access is needed and how to request another appointment. Avoid technical language that obscures the practical arrangements.

Separate a provisional programme from a confirmed visit. If the appointment changes, tell the resident through the agreed channel and update the shared record. Do not leave the site team and resident liaison team working from different versions.

Record support requirements sensitively and share only what is needed to arrange the work. Do not place personal details in open site schedules or general photographic records.

Treat temporary conditions as part of the job

Work can temporarily alter the protection that occupants normally rely on. HSE's fire safety in construction guidance addresses the relationship between construction activity and occupied premises. Temporary fire precautions and any arrangements for continued occupation require competent, project-specific planning.

The programme should identify work stages affecting compartment boundaries, doors, escape routes or essential systems, together with the agreed controls and responsibilities. Any planned isolation or impairment must follow the site's authorised process. Contractors should know when to stop and seek direction if conditions differ from the plan.

Do not use a standard end-of-day checklist as a substitute for assessing the work. Use it to confirm that the agreed arrangements have been followed, that unresolved concerns have been escalated and that the next team has the information it needs.

Make unsuccessful visits visible

Keep a distinction between an appointment offered, confirmed, attempted and completed. Record the practical reason for an unsuccessful visit and the next action without unnecessary personal commentary.

Missed access should stay visible in the works register. It is not a completed inspection or a completed repair. Review repeat difficulties with the client's authorised team so that the appropriate engagement and access process can continue.

Progress reporting is more useful when it shows both completed tasks and the causes preventing remaining work. A list of outstanding locations with named owners gives the client something actionable.

Hand over by location and phase

Where a programme runs for several weeks, agree phased handovers rather than waiting until the final day to review all evidence. Reconcile survey references, completed work and remaining actions while the relevant team is still available.

Interseal's historical Fabrick Group case study describes occupied social housing work involving resident liaison, multiple trades and planned sequencing. It illustrates why these arrangements belong in the project scope.

When preparing a new programme, send the findings, building information and occupancy constraints with your request for a quotation. A useful proposal should explain how the work and its access requirements fit together.
