Why Refurbishment and Demolition Surveys Are Essential Before Construction Work Starts

Jul 10, 2026

Before any commercial refurbishment, strip-out, structural alteration or demolition project begins, asbestos risk must be properly assessed. For buildings constructed or refurbished before 2000, asbestos-containing materials may still be present in the building fabric, services, plant areas, roofs, ceilings, floors, walls, ducts and voids.

A refurbishment and demolition asbestos survey, often called an R&D survey, is designed to identify asbestos-containing materials that could be disturbed during planned construction work. It is more intrusive than a standard management survey and is an essential part of safe project planning.

For contractors, developers, project managers, building owners and dutyholders, the survey is not just a compliance document. It helps prevent accidental asbestos disturbance, protects workers and building users, supports accurate pricing, reduces delays and allows asbestos removal to be planned before main works begin.

HSE’s asbestos survey guide, HSG264, is aimed at people carrying out asbestos surveys and those with responsibilities for managing asbestos in non-domestic premises under the Control of Asbestos Regulations 2012. It covers survey planning, carrying out asbestos surveys, survey reports and the dutyholder’s use of survey information.

This guide explains when refurbishment and demolition surveys are required, how they differ from management surveys, what they should cover, and why they are so important before construction work starts.

What Is a Refurbishment and Demolition Asbestos Survey?

A refurbishment and demolition asbestos survey is an intrusive asbestos survey carried out before work that will disturb the building fabric. Its purpose is to locate, as far as reasonably practicable, asbestos-containing materials within the areas affected by the planned works.

This type of survey may involve opening up parts of the building, inspecting concealed spaces and taking samples of suspect materials for laboratory analysis. The survey should be tailored to the scope of works. A small refurbishment in one part of a building does not necessarily require the whole building to be surveyed, but every area and material likely to be disturbed by the project should be properly assessed.

A refurbishment and demolition survey may be needed before:

  • Office refurbishment
  • Retail fit-out or strip-out
  • Commercial property refurbishment
  • Industrial unit reconfiguration
  • Warehouse works
  • Plant room upgrades
  • Boiler replacement
  • Electrical rewiring
  • HVAC installation
  • Data cabling
  • Lift replacement
  • Fire safety works
  • Roof replacement
  • Ceiling or floor removal
  • Structural alterations
  • Partial demolition
  • Full demolition
  • Change of use projects

The key issue is whether the work will disturb the building fabric. If it will, a management survey alone may not be enough.

Crucial Environmental provides commercial asbestos surveys for refurbishment, demolition and construction projects across the UK.

How Is an R&D Survey Different From a Management Survey?

A management survey is designed to support normal occupation and routine maintenance. It helps the dutyholder prepare an asbestos register and asbestos management plan, allowing asbestos-containing materials to be managed while the building remains in use. HSE states that the main aim of a management survey is to allow the dutyholder to produce an asbestos register and asbestos management plan, helping manage asbestos-containing materials during normal occupation and use.

A refurbishment and demolition survey has a different purpose. It is used before intrusive work. It is more invasive because it needs to identify asbestos that may be hidden behind finishes, within voids, beneath floors, above ceilings or inside service areas.

For example, a management survey might record visible asbestos-containing floor tiles in a corridor but may not inspect beneath those tiles or behind fixed skirting. It may record accessible asbestos insulation board panels but not open sealed risers or wall cavities. It may inspect a plant room visually but not dismantle boxing around old pipework.

That is acceptable for normal management, but it may not be enough when contractors are about to strip out, drill, cut, remove or demolish those areas.

For construction projects, the difference is critical. A management survey tells you what is known and accessible during normal use. An R&D survey investigates what could be disturbed by the planned works.

Why R&D Surveys Are Essential Before Construction Work

Construction work can disturb hidden asbestos-containing materials quickly. Once strip-out or demolition begins, materials that were previously sealed away may be broken, drilled, cut or removed.

An R&D survey helps project teams avoid this by identifying asbestos before the work starts.

Protecting Workers and Contractors

Construction workers, demolition contractors, plumbers, electricians, joiners, HVAC contractors, roofers, lift engineers and other trades may disturb asbestos if it has not been identified. Because asbestos fibres cannot be seen or smelled, workers may not realise they have been exposed until after the event.

A suitable survey allows asbestos risks to be recorded, communicated and controlled before contractors enter the work area.

Avoiding Project Delays

Unexpected asbestos discoveries can stop work immediately. The area may need to be isolated, sampling may be required, asbestos removal may need to be arranged, and method statements may need to be revised.

This can cause serious disruption to construction programmes, particularly where works are taking place during a limited shutdown period, school holiday, tenant handover, retail fit-out window or planned demolition sequence.

Supporting Accurate Tendering and Budgeting

Asbestos can have a major impact on cost. If asbestos removal is identified early, it can be priced and programmed properly. If it is found late, clients may face additional costs, delays and disputes.

Developers and project managers should ensure asbestos information is available before contractor pricing wherever possible.

Reducing Legal and Compliance Risk

The Control of Asbestos Regulations 2012 require asbestos risks to be properly managed. For non-domestic premises, dutyholders need to know whether asbestos is present and how it could be disturbed. A suitable R&D survey supports safe planning and helps demonstrate that asbestos risk has been considered before work begins.

Planning Safe Asbestos Removal

Where asbestos-containing materials need to be removed before construction works, the survey provides the information needed to plan the removal safely. This may include the material type, location, extent, condition and access requirements.

Crucial Environmental provides licensed asbestos removal where higher-risk asbestos materials need to be removed before refurbishment or demolition proceeds.

When Is a Refurbishment and Demolition Survey Required?

A refurbishment and demolition survey should be considered whenever work will disturb the building fabric in a commercial property that may contain asbestos.

This includes buildings built or refurbished before 2000, as asbestos was widely used in UK construction before being banned. In practice, project teams should treat pre-2000 buildings as potential asbestos risks unless suitable evidence confirms otherwise.

An R&D survey may be required before:

Refurbishment Works

This includes works that alter rooms, finishes, services or layouts. Examples include office refurbishments, school upgrades, healthcare alterations, hospitality fit-outs, factory refurbishments and commercial unit reconfigurations.

Strip-Out Works

Strip-out often involves removing ceilings, partitions, floor coverings, wall linings, services, fixtures and fittings. This can disturb asbestos hidden behind modern finishes.

Demolition Works

Demolition can disturb almost every part of a structure. A demolition asbestos survey is essential before full or partial demolition of buildings that may contain asbestos.

Mechanical and Electrical Works

Electrical rewiring, data cabling, ventilation upgrades, heating system changes and plant room works can all disturb voids, panels, insulation and service routes.

Roof Works

Roof repairs, replacement, solar installation and cladding works can disturb asbestos cement sheets, soffits, gutters, downpipes, roof voids and old insulation.

Lift and Riser Works

Lift shaft works, service riser access and vertical service routes often involve areas that were not fully inspected during a management survey.

Change of Use Projects

Changing a building’s use often involves intrusive adaptations, new layouts and service upgrades. Asbestos risk should be assessed before designs and costs are finalised.

Crucial Environmental supports commercial clients through our Construction & Built Environment asbestos services, including support for Demolition and Developers & Project Managers.

What Areas Should the Survey Cover?

An R&D survey should be planned around the scope of works. A good survey does not simply inspect the obvious areas; it considers how contractors will actually carry out the project and which materials may be disturbed.

Depending on the work, the survey may need to cover:

  • Ceiling voids
  • Wall cavities
  • Floor voids
  • Service risers
  • Lift shafts
  • Plant rooms
  • Boiler rooms
  • Roof spaces
  • Basements
  • Ducts and service routes
  • Pipework and insulation
  • Fire protection materials
  • Structural steel fireproofing
  • Partition walls
  • Floor finishes and adhesives
  • Roof sheets and cladding
  • External panels
  • Soffits, gutters and downpipes
  • Electrical cupboards and backing boards
  • Redundant equipment areas
  • Outbuildings and connected structures

For demolition, the survey may need to cover the whole building. For refurbishment, it may only need to cover the areas affected by the proposed works. However, the scope must be detailed enough to avoid gaps.

If part of the building cannot be accessed, this should be clearly recorded and managed. Areas not accessed may need to be presumed to contain asbestos until further investigation is carried out.

Why Survey Scope Is So Important

The quality of an R&D survey depends heavily on the scope. If the surveyor does not know what work is planned, they may not inspect the right areas.

For example, if a project involves new cable routes through a riser, the survey must include that riser and any materials that will be disturbed. If a refurbishment involves removing floors, the survey should consider floor tiles, adhesives, screeds and voids. If a roof replacement is planned, the survey should cover roof sheets, soffits, gutters, panels and any associated debris or insulation.

Before instructing a survey, clients and project teams should provide:

  • Drawings or plans
  • Scope of works
  • Areas to be refurbished or demolished
  • Proposed service routes
  • Details of intrusive works
  • Access constraints
  • Programme requirements
  • Known asbestos information
  • Areas of previous removal or encapsulation
  • Any suspected materials or site concerns

This helps ensure the survey provides useful information for the actual project, not just a general overview.

What Happens During an R&D Survey?

The survey process will vary depending on the building and project scope, but it usually involves several stages.

Planning and Review

The surveyor reviews existing asbestos records, building information, drawings and the proposed scope of works. This helps identify likely asbestos locations and access requirements.

Site Inspection

The surveyor inspects the relevant areas of the building. Because R&D surveys are intrusive, this may involve opening voids, removing small sections of materials, accessing hidden spaces or inspecting areas not covered by previous management surveys.

Sampling

Suspect materials are sampled and sent for laboratory analysis. Sampling must be carried out safely and competently to avoid unnecessary fibre release.

Laboratory Analysis

Samples are analysed to confirm whether asbestos is present. Crucial Environmental operates its own UKAS-accredited asbestos laboratory at its Worthing head office, enabling fast and reliable asbestos testing for commercial projects.

Reporting

The survey report identifies asbestos-containing materials found, their locations, sample results, material types, extent, condition and recommendations. It should also identify any areas that were not accessed.

Project Planning

The client, project manager or principal contractor uses the survey information to plan the works. This may involve asbestos removal, encapsulation, revised sequencing, air monitoring, contractor briefings and updates to health and safety documentation.

What Should Be Included in the Survey Report?

A refurbishment and demolition asbestos survey report should be clear, practical and usable by project teams. It should not simply list sample results without explaining where materials are and how they affect the works.

A useful report should include:

  • Building and survey details
  • Survey scope
  • Areas inspected
  • Areas not accessed
  • Asbestos-containing materials identified
  • Sample results
  • Material locations
  • Photographs
  • Plans or marked-up drawings where appropriate
  • Material condition
  • Recommendations
  • Any urgent actions
  • Limitations of the survey
  • Information needed before works continue

The report should be shared with those who need it, including the client, principal designer, principal contractor, demolition contractor, refurbishment contractor, asbestos removal contractor and relevant trades.

What Happens if Asbestos Is Found?

Finding asbestos during an R&D survey is not unusual. In fact, that is exactly why the survey is carried out before works begin. The important thing is that asbestos is identified early enough to plan the correct response.

If asbestos is found, the project team should consider:

  • What type of asbestos-containing material has been identified?
  • Where is it located?
  • What condition is it in?
  • Will the planned works disturb it?
  • Can the design or method be changed to avoid disturbance?
  • Does it need removal before works start?
  • Does removal need a licensed asbestos contractor?
  • Is air testing or clearance required?
  • How will waste be handled?
  • How will follow-on contractors be briefed?

Some asbestos-containing materials can be managed in place if they are not being disturbed. However, in refurbishment and demolition projects, asbestos that will be disturbed usually needs to be removed under controlled conditions before other works continue.

When Licensed Asbestos Removal May Be Needed

Some asbestos work must be carried out by a licensed asbestos removal contractor. This usually applies to higher-risk asbestos materials or work that is more likely to release fibres.

Licensed asbestos removal may be needed for materials such as:

  • Asbestos insulation board
  • Pipe lagging
  • Sprayed coatings
  • Loose fill insulation
  • Asbestos-contaminated debris
  • Higher-risk fire protection materials

Other asbestos work may be non-licensed or notifiable non-licensed, depending on the material, condition and nature of the work. The correct classification should be decided by competent professionals.

Crucial Environmental provides commercial licensed asbestos removal to support refurbishment, demolition, construction and enabling works across the UK.

Air Testing After Asbestos Removal

Air testing and air monitoring may be required during or after asbestos removal, following suspected disturbance, or where reassurance is needed before work areas are handed back.

Air testing and air monitoring may be relevant where:

  • Licensed asbestos removal has taken place
  • Enclosures have been used
  • Clearance is required before follow-on trades enter
  • Work is taking place in an occupied or sensitive building
  • Asbestos has been accidentally disturbed
  • A client or contractor requires reassurance
  • Areas need to be handed back quickly and safely

Air monitoring provides evidence that asbestos risks have been controlled. This can be particularly important when construction programmes depend on timely handover from asbestos removal to main works.

The Role of the Client, Principal Designer and Principal Contractor

Asbestos planning should not sit in isolation. It should be part of the wider construction planning process.

Clients should make sure suitable asbestos information is available before works are procured and started. Principal designers should consider asbestos during design and pre-construction planning. Principal contractors should ensure asbestos risks are understood and controlled during the construction phase.

Contractors should not begin intrusive works unless they have enough information to confirm that the work area is safe or that asbestos risks have been properly controlled.

For commercial projects, the asbestos survey should be part of the pre-construction information and should be reviewed alongside drawings, specifications, risk assessments, method statements and the construction phase plan.

Common Problems When R&D Surveys Are Missed

Failing to arrange a suitable refurbishment and demolition survey can cause significant problems.

Common issues include:

  • Contractors disturbing asbestos unexpectedly
  • Site shutdowns
  • Emergency sampling and testing
  • Delays to strip-out or demolition
  • Unplanned asbestos removal costs
  • Disputes between clients and contractors
  • Revised programmes
  • Poor tender accuracy
  • Exposure concerns
  • Enforcement risk
  • Damage to client reputation

Many of these issues can be avoided by arranging the correct survey at the right time.

Common Misunderstandings About R&D Surveys

“We Already Have an Asbestos Register”

An asbestos register is important, but it may be based on a management survey. It may not cover concealed areas that will be disturbed during refurbishment or demolition.

“The Building Has Been Refurbished Before”

Previous refurbishment does not guarantee asbestos has been removed. Asbestos may remain behind later finishes, in voids, in service areas or in parts of the building not previously disturbed.

“The Work Is Only Minor”

Even small works can disturb asbestos. Drilling, fixing, cutting, lifting floors or opening panels can create risk if the material contains asbestos.

“The Contractor Will Know if It Is Asbestos”

Asbestos cannot be reliably identified by appearance. Suspect materials should be assessed and tested.

“We Can Survey Once Work Starts”

Waiting until work starts can cause delays and may expose contractors to avoidable risk. Surveys should be completed before intrusive works begin.

Practical Checklist Before Refurbishment or Demolition Starts

Commercial clients, contractors and project managers should check:

  • Was the building built or refurbished before 2000?
  • Is there an existing asbestos register?
  • Is the existing survey a management survey or an R&D survey?
  • Does the survey cover the exact work areas?
  • Are any areas marked as not accessed?
  • Will the work involve drilling, cutting, removal, strip-out or demolition?
  • Has a refurbishment and demolition survey been completed where required?
  • Have suspect materials been sampled and tested?
  • Has asbestos removal been planned before main works?
  • Does any work require a licensed asbestos contractor?
  • Is air testing or clearance required?
  • Have contractors been briefed on asbestos risks?
  • Has the asbestos information been included in project documentation?
  • Will asbestos records be updated after the works?

This checklist helps prevent asbestos from becoming a late-stage project problem.
