How to keep residents safe during occupied refurbishment

Start with a real doorway, not a site boundary on a drawing

A contractor is replacing windows in an occupied block of flats. The approved plan puts the materials hoist outside the rear elevation and keeps residents on the normal front entrance route. On Monday morning a delivery cannot reach the rear gate. The driver unloads at the front, a short scaffold tube stack appears in the lobby, and a worker moves a barrier so trolleys can pass. Residents can still get through, but they now walk beside unloading, stored materials and an opening to the work area. The drawing still shows a safe route. The actual building does not.

The immediate task is to restore a protected route or pause the activity that conflicts with it. A sign saying “take care” does not control a falling object, reversing vehicle or open work zone. Neither does asking residents to squeeze through while a delivery finishes. The site supervisor and building representative need to see the route as a resident experiences it, decide what work must stop, and agree a safe temporary arrangement before movement resumes. Where the normal route cannot be made safe, an alternative route or temporary change in occupation may need competent consideration. The answer depends on the building and the people who use it.

HSE's public protection guidance makes clear that construction work must not put members of the public at risk. It identifies access control, falling objects, vehicles, excavations and vulnerable groups as recurring issues. Its more detailed Protecting the public guidance has a section on occupied residential refurbishment. It addresses separation, storage, communication, alternative routes and the possibility that temporary evacuation may be needed for particular work. That publication uses some older CDM role terminology. Use the current HSE principal contractor guidance to identify contemporary construction-phase coordination responsibilities.

This is an operational guide for the interface between a live home and a changing construction site. It does not grant permission to block an escape route, decide a resident's housing rights, certify a fire strategy or replace a site-specific risk assessment. The person controlling the work must use competent advice and the building's actual arrangements to make those decisions.

Decide whether residents can remain before choosing a diversion

The first question is not where to put the barrier. It is whether the work can safely take place while people remain in the affected homes or shared areas. Consider the nature of the task, the duration, the substances and equipment used, who may be exposed, the route that must remain available, and the consequence of moving people. A short window replacement may need a temporary room exclusion. Work that affects shared escape, a main entrance or hazardous material may require a much wider arrangement. Do not assume that a job is minor because it lasts one day.

HSE's residential refurbishment guidance says occupants often remain during smaller works, but the precautions must then be reconsidered to control risk to residents and workers. It also recognises that some short tasks can warrant temporary evacuation. This is guidance about assessing the actual risk, not a blanket rule that all refurbishment requires residents to move. Conversely, a resident's preference to remain does not make an unsafe route safe. If the proposed controls cannot protect the people affected, the work method, timing or occupancy arrangement must change.

Bring the client or housing operator, principal contractor where appointed, relevant designer and building fire lead into this decision early. The client knows occupancy, services, access needs and the building's normal operation. The contractor knows the work sequence, plant, storage and likely changes. The fire lead knows the existing escape strategy and systems. Nobody should approve the interface by looking only at their own plan. A route that is clear of construction debris may still fail if it passes a disabled resident's inaccessible stair, a locked door or a fire door held open for material movement.

Record the decision at the level at which it can be used. “Residents may remain” is too broad. State which homes, floors, entrances and times are affected; which route stays open; what will happen if the route cannot be maintained; and who may suspend work. If a temporary move is proposed, involve the housing and resident teams in the practical consequences. This page does not set notice periods, compensation or entitlement rules because those depend on the specific tenancy, lease, works programme and legal setting.

Walk the resident journey in both directions

Trace a normal resident trip from the dwelling door to the pavement and back. Include the lift, stair, lobby, bin store, parking area and any passage used for deliveries or emergency access. Then trace a trip during a delivery, a shift change and after workers have left. A route can be safe at 10 a.m. and obstructed at 4 p.m. when rubbish bags, scaffold components and tools accumulate. A line on a plan will not reveal a protruding fixing at a child's height or a temporary cable across a threshold.

Check width, surface, lighting, visibility, doors and turning space against the needs of people who actually use the route. A pushchair, wheelchair, walking frame or assistance from another person can change whether a temporary passage is usable. Ask residents about relevant access needs without collecting more personal information than the team needs. HSE's residential guidance suggests obtaining information about special access requirements, but that is not permission to circulate medical details to every trade. Translate an individual need into the route requirement, share it with the people who must act and protect the underlying information.

Observe how the route intersects the work. Can debris or tools fall from above? Can a delivery vehicle swing across it? Does a work bay open directly into it? Can dust or fumes escape? Is scaffold climbable from a shared area? Are materials stored where they could fall or roll? Is a resident likely to take a shortcut because the diversion is unclear or inconvenient? The route assessment should reflect predictable human behaviour, not only the path the project team hopes people will use.

Make a simple route sketch that shows occupied doors, work zones, deliveries, protected walkways, barriers, lighting, emergency escape and accessible alternatives. Date it. Put the same version in the site briefing and resident communication. If a route changes, withdraw the old sketch and explain the new one before people encounter it. An old notice in a lobby is worse than no notice if it directs someone toward a live hazard.

Build separation that survives the working day

Use physical separation suited to the hazard and the surrounding population. A light marker may show a diversion, but it cannot necessarily stop someone entering a hazardous work zone or protect them from falling material. HSE advises defining and maintaining site boundaries and choosing fencing for the actual site and surroundings. It gives examples of more substantial fencing in populated areas, but no single height or material should be copied as a universal answer for every internal corridor. Choose the barrier through the site-specific public protection assessment.

Assign someone to install, inspect, move and restore each barrier. The point of failure is often not initial setup. A trade shifts a panel for a trolley and leaves it open. A cleaner moves tape to reach a bin. A resident holds a gate while a visitor passes. A delivery driver unloads outside the designated bay. A barrier that depends on every passing person remembering a verbal instruction is weak protection. Use a design that stays in place through normal activity and a controlled method for any temporary opening.

Where work takes place above or beside a route, consider both preventing material from falling and protecting or excluding people beneath. HSE lists covered walkways and other physical measures as possible controls when falling objects threaten the public. A covered route is not automatically safe merely because it has a roof. A competent person must assess the expected material, the work above, support and maintenance. The work plan may be safer if noisy or overhead operations are shifted to a time when the affected route can be closed without leaving residents stranded.

Keep materials in a controlled compound or work zone, not in a shared corridor because it is convenient. HSE's residential guidance describes an incident involving scaffold tubes left against a wall in a block corridor and falling as a resident passed. The lesson is practical: temporary storage must be secure and must not erode the protected passage. Include waste, empty pallets, gas cylinders, ladders and small tools in the same discipline. A clear route should remain clear when the crew takes a break.

Give the fire route its own decision

Normal circulation and fire escape are related but different. A diversion can be pleasant and accessible in daily use yet fail the building's emergency strategy. HSE's construction fire guidance says work in an occupied building must not interfere with existing escape routes, fire separation, alarms, dry risers or sprinkler systems. Its Fire safety in construction guidance addresses the coordination needed when a building remains partly occupied. A principal contractor's construction site arrangements and the building's occupied-part fire responsibilities both need to be understood.

Before a stair, lobby or door is changed, ask who owns the current fire risk assessment and escape strategy, what the proposed work affects, and what competent fire review is required. A proposed alternative stair may not have the right capacity, travel arrangement, signage, lighting or access for everyone who relies on it. A temporary door may alter compartmentation. Propping a fire door open so contractors can move materials creates a different problem from the one the diversion was meant to solve. The construction team should not declare an alternative escape route adequate from a site plan alone.

HSE's residential guidance advises seeking local fire authority advice where permanent escape routes must be blocked or altered. The exact liaison route and necessary approvals should be checked for the building and jurisdiction. Do not treat a notice to residents or an internal permit as approval to compromise escape. If the escape arrangement cannot be established, keep the affected operation on hold. The building fire lead and competent adviser should agree the temporary state and how it will be checked while work progresses.

Brief workers on the same emergency route residents will use. Tell them where they must not store materials, how they must handle fire doors, what alarm changes are in place and whom to contact if a system is impaired. A new route is not controlled until both groups know it. At the end of a shift, confirm that temporary barriers, doors and signs have not made the agreed fire arrangement less safe than it was when work started.

Plan deliveries around homes, not only the crane or van

Deliveries can defeat a protected route in minutes. Plan where vehicles wait, turn and unload; how loads enter the work zone; and whether a resident route crosses that movement. HSE's site traffic guidance says vehicle and pedestrian movements should be organised safely. Its public protection page points out that a delivery blocking a pavement can push pedestrians into the road. The project should solve the delivery problem before the vehicle arrives, not ask residents to improvise around it.

Give drivers an arrival point and a person authorised to accept or turn away a load. If the planned bay is unavailable, pause the unloading decision. Do not create a new drop point across the main entrance without assessing pedestrians, vehicle movement, overhead work and the effect on escape. The safe answer may be a rescheduled delivery, smaller load, different gate or temporary controlled closure with an agreed alternative route. If a public footway or highway is involved, the relevant authority and permissions may also matter. A site supervisor cannot create public-space permission by drawing a cone line.

Arrange lifting, waste removal and scaffold work with the resident route in mind. Do not schedule an overhead lift above a path simply because residents are usually indoors at that hour. Some people leave early, return late or work shifts. If a temporary exclusion is necessary, the housing team must know how every affected person will enter or leave while it is in force. A resident cannot be treated like a site worker who can wait in a compound until the lift is finished.

Communicate a usable plan to residents

Good communication is a risk control when it tells people what will change and gives them a practical way to act. HSE's residential refurbishment guidance recommends early information to residents and a named liaison point for the client and principal contractor. Give each affected household the work area, dates and likely noisy or restricted periods; the route that remains available; any temporary entrance; how deliveries will be separated; whom to contact during and after working hours; and what to do if the route is blocked or unsafe. Give the same information in formats people can use.

Avoid a notice that promises a route will remain open if the programme may change it. State the condition: the route is the agreed access until a dated replacement notice and physical route are in place. Put notice where residents actually see it, but do not rely on lobby posters alone for a change that affects a particular household. Some residents may be away when work starts. Others may not read English comfortably or may need a different format. The housing operator should choose the communication method with those realities in mind.

Offer a clear way to report a blocked route, damaged barrier, suspicious person, dust ingress or inaccessible diversion. The report should reach someone who can stop or change the work, not only a general customer service queue. Record what was reported, the time, the interim protection and the response. Do not answer a resident's safety concern with a generic assurance that the contractor has a risk assessment. Check the location and show the control that addresses it.

Protect privacy. A route plan may need to know that a household requires step-free access or extra time, but it rarely needs a diagnosis. Keep resident information with those who need it, make the operational requirement clear to the site team, and set a route for correcting mistakes. A resident who says a diversion is unusable has provided evidence that the arrangement needs review, even if the drawing is signed.

Check the route whenever the work changes

Treat the resident route as a live control. Inspect it before work starts, after barriers or deliveries move, after a change in workface, after severe weather and before the team leaves. The check is physical: walk it, test doors as appropriate, look for loose materials, confirm signs and lighting, and verify the work zone remains separated. A photograph can support the record, but it does not prove a route was accessible to a particular resident or that the fire strategy was sound.

Set stop triggers in advance. Examples include a barrier that no longer encloses the work, a blocked escape door, a vehicle occupying the protected path, a trip hazard created by temporary services, a falling-object risk above the walkway, or a resident unable to use the diversion. Stop the affected work or access movement, protect people, and get the competent person to reassess. Do not wait for the next daily meeting because the signed plan still says the route is open.

Use a small change log that identifies the old arrangement, the proposed new one, reason for change, people affected, fire and accessibility checks, barriers and signs to alter, resident communication, named approval and first-use observation. The point is to prevent a trade-level adjustment from silently changing a building-level safety decision. Where a construction phase plan, method statement, fire assessment or resident notice is affected, update the controlled version and brief the people who act on it. A changed sketch kept only on a supervisor's phone is not a communicated route.

Ask one person from the housing or building team and one from the construction team to test the first use where practicable. The site team can identify the work hazard; the building team can identify residents' normal movement and access needs. If their observations conflict, resolve the conflict before the route is treated as released. Some jobs also need a fire specialist or other competent reviewer. Do not let the presence of two signatures create false confidence about a technical question neither person can answer.

Hand back each day and at each phase boundary

Daily handback matters because residents use the building after the contractor leaves. Check that tools, waste and materials are secure; barriers are stable; gates and doors are in the agreed state; temporary lighting works; signs reflect the route; lifts and shared services affected by the work have been handed over; and the fire arrangement remains as agreed. Look for anything a child could climb or move. HSE highlights securing access equipment, plant and hazardous materials at the end of the day in its public protection guidance.

Do not reopen a closed route simply because the noisy task ended. A work bay may still contain loose fixings, exposed services, incomplete guarding, wet surfaces or unsecured materials. Name who has authority to release the area to residents and what they must inspect. If part of the route remains restricted, leave a clear alternative and tell residents when the next decision will be made. A contractor's “finished” message and a housing operator's “safe for residents” decision are separate steps.

At phase handover, update the route map and resident message. New scaffolding, changed entrances and successive trades can make a once safe route obsolete. Transfer outstanding conditions to the next supervisor with a named owner and deadline. If a defect cannot be corrected before the next shift, maintain the protective arrangement and make sure out-of-hours contacts know what to do. Repeated minor obstructions should prompt a review of delivery and storage design, not just another reminder to tidy up.

The useful record is concise but complete: versioned route plan, occupancy decision, resident access needs translated into practical controls, fire review, barrier and delivery plan, inspection findings, change decisions, resident notices, complaints and responses, daily handback and final release. Keep personal details appropriately restricted. The record should allow another competent person to reconstruct why a route was considered safe on a particular day.

A ten-minute route review before the next shift

Use these questions at the site and building interface. They are prompts for observation, not a substitute for competent assessment.

Suppose the answers are yes at shift start but a delivery moves the barrier at noon. The review is not a once-daily certificate. The person who changes the physical arrangement must trigger a fresh check and, if necessary, a new decision. That is the practical meaning of managing an occupied building rather than treating it as an empty construction site.

Suggested CTA: Use a shared resident-route change record before moving a barrier, delivery point or entrance. Capture the physical check, affected households, fire and access decisions, notice and named release. Confirm the available Complys workflow with its product owner before publication.

It must not auto-certify escape adequacy or decide housing rights.
