Survey before structural demolition

What is a Demolition Asbestos Survey?

A Demolition Asbestos Survey is a highly intrusive inspection designed to locate and identify asbestos-containing materials throughout the parts of a building or structure that will be demolished.

Demolition can expose materials that have remained concealed behind walls, above ceilings, beneath floors, inside service risers, around structural members and within plant or equipment for decades.

The survey therefore needs to investigate significantly further into the structure than a normal Management Survey and usually further than a refurbishment survey restricted to a smaller work area.

The demolition boundary determines the survey boundary.

For full demolition, the survey strategy should consider the complete structure. For partial demolition, it should cover all parts of the building that will be removed or disturbed and appropriate adjoining areas where the demolition work could encounter concealed ACMs.

Before major structural work begins

When is a Demolition Asbestos Survey needed?

Where a building or part of a structure is going to be demolished and asbestos may be present, the asbestos information must be sufficiently detailed for the demolition work being planned.

HSE guidance states that a refurbishment or demolition survey should locate and identify asbestos-containing materials, including materials hidden within the building fabric, before structural work begins.

Full building demolition

Complete demolition and site clearance of houses, commercial buildings, industrial units and other structures.

Partial demolition

Removal of wings, extensions, elevations, structures or substantial sections while other areas remain.

Industrial clearance

Factories, workshops, warehouses, plant buildings and industrial structures scheduled for demolition or decommissioning.

Housing regeneration

Individual homes, residential blocks, estates and regeneration programmes where existing structures are being cleared.

Commercial redevelopment

Buildings being cleared to enable redevelopment, reconstruction or a new commercial use.

Infrastructure projects

Ancillary structures, plant buildings and other assets being demolished as part of wider infrastructure schemes.

From one structure to large demolition programmes

Projects that commonly need pre-demolition asbestos information

Commercial buildings Offices, retail property, hotels and mixed commercial premises.
Industrial buildings Factories, workshops, warehouses and production facilities.
Residential property Houses, flats and larger housing regeneration schemes.
Schools Teaching blocks, temporary structures, plant areas and redundant buildings.
Healthcare estates Redundant buildings, service structures and phased redevelopment areas.
Warehouses Distribution units, storage buildings and former industrial premises.
Plant rooms Boiler houses, service buildings and mechanical installations.
Site clearance Multiple structures being cleared ahead of new development.
Garage demolition Domestic and commercial garages, stores and outbuildings.
Agricultural buildings Sheds, workshops, stores and older farm structures.
Former public buildings Council property, community buildings and redundant facilities.
Multi-building sites Large redevelopment areas involving several different structures.

Major Projects · Redevelopment · Acquisitions

Demolition surveys are often one part of a much larger project

For major redevelopment, portfolio acquisitions and multi-building demolition programmes, the asbestos survey should connect with the wider project rather than sit as an isolated report. ASM can review existing information, drawings, demolition boundaries and planned works before defining the investigation required for tendering, remediation and project mobilisation.

CAR 2012 • HSG264 • Construction planning

Asbestos should be dealt with before demolition starts

HSE states that there is a legal requirement for asbestos-containing materials to be removed, so far as reasonably practicable, before major refurbishment or demolition.

This means asbestos information must be obtained early enough for the findings to influence demolition design, tendering, asbestos removal, sequencing, programme and site controls.

01

Define demolition

Establish exactly which structures and building elements will be demolished.

02

Investigate ACMs

Complete an appropriately intrusive survey of the defined demolition boundary.

03

Plan asbestos works

Identify materials requiring removal or other controls before structural demolition begins.

04

Demolish safely

Provide relevant asbestos information to the organisations carrying out and managing the work.

Highly intrusive inspection

How intrusive is a Demolition Asbestos Survey?

A demolition survey is designed to investigate concealed areas that could otherwise only become visible once the building is physically broken apart.

Areas that may need investigation

  • Ceiling voids
  • Wall cavities and partitions
  • Service risers and ducts
  • Pipework and concealed insulation
  • Floor constructions and floor voids
  • Plant rooms and boiler areas
  • Roof structures and coverings
  • Soffits and external panels
  • Structural columns and beams
  • Fire protection materials
  • Lift shafts and service areas
  • Other concealed construction layers

Information to provide ASM

  • Site address and building list
  • Demolition drawings
  • Demolition boundary
  • Structural plans where available
  • Previous asbestos surveys
  • Existing asbestos register
  • Site photographs
  • Building construction details
  • Access restrictions
  • Known live services
  • Required demolition programme
  • Required reporting date
The surveyed area should be vacant and controlled.

HSE guidance states that refurbishment and demolition surveys involve destructive inspection and potential asbestos disturbance. The relevant area therefore needs to be vacated during the inspection and appropriately controlled.

The reason demolition surveys are intrusive

Where can asbestos remain hidden before demolition?

Many asbestos-containing materials can remain concealed throughout the life of a building and may not be identified during normal occupation or routine maintenance.

Walls & partitions

Insulation board, fire breaks, packing materials, panels and concealed linings.

Ceilings & voids

AIB, sprayed coatings, service insulation, fire protection and inaccessible ceiling components.

Floors

Thermoplastic tiles, bitumen adhesives, paper linings and materials beneath later floor finishes.

Pipework & services

Pipe insulation, gaskets, rope seals, equipment components and service penetration materials.

Structural elements

Fire protection around steelwork, shuttering remnants and concealed boards or insulation.

Roof & external fabric

Cement sheets, panels, soffits, rainwater goods, roof products and weather-resistant asbestos materials.

How an ASM Demolition Asbestos Survey works

01

Review the project

We review the building, demolition strategy, plans and existing asbestos information.

02

Define the boundary

Full or partial demolition areas are clearly agreed before survey planning begins.

03

Plan safe access

Access, isolation, structural condition, services and intrusive inspection requirements are considered.

04

Intrusive inspection

Surveyors investigate accessible and concealed areas throughout the agreed demolition scope.

05

Sampling & analysis

Representative samples of suspect materials are taken and analysed where required.

06

Issue the report

The report records identified ACMs, sample results, locations, photographs, extent, restrictions and recommended actions.

Information for demolition planning

What should a Demolition Asbestos Survey report contain?

The report should give the project team clear information about asbestos within the demolition boundary and identify any remaining limitations before demolition proceeds.

  • Site and building identification
  • Full or partial demolition scope
  • Survey methodology
  • Areas and structures inspected
  • Intrusive access undertaken
  • Known and identified ACM locations
  • Material descriptions
  • Approximate extent or quantity
  • Photographic references
  • Sample identification
  • Laboratory analysis results
  • Remaining restrictions or exclusions
  • Recommendations for asbestos works

Use the report before demolition tendering and mobilisation

Obtaining the information early allows asbestos-related costs, programme requirements and enabling works to be considered before demolition starts.

Relevant information can then be issued to the demolition contractor and asbestos contractor so the work sequence can be properly coordinated.

If the demolition design or boundary changes, the asbestos survey should be checked against the revised scope.

Demolition Survey FAQs

Demolition Asbestos Survey questions

What is a Demolition Asbestos Survey?

A Demolition Asbestos Survey is a highly intrusive asbestos inspection covering the parts of a building or structure that will be demolished. Its purpose is to locate ACMs before structural demolition begins.

Do I need an asbestos survey before demolition?

Where asbestos may be present, the asbestos information must be sufficient for the demolition works. A properly scoped demolition survey is normally used to investigate the demolition boundary before structural work begins.

Is a Demolition Survey fully intrusive?

Yes. The objective is to investigate concealed building areas that could contain asbestos and that will become disturbed during demolition. Significant opening-up and damage may therefore be necessary.

Can a Demolition Survey be carried out while the building is occupied?

The area being subjected to intrusive refurbishment or demolition surveying should be vacant and controlled during the inspection because destructive investigation can potentially disturb asbestos-containing materials.

What is the difference between a Refurbishment and Demolition Survey?

A Refurbishment Survey is normally targeted to defined parts of a building being altered. A Demolition Survey is intended to investigate the complete defined demolition boundary at the level of intrusion necessary before the structure is demolished.

Does a Demolition Survey include asbestos sampling?

Representative samples of suspect materials are normally taken where laboratory confirmation is required and where sampling falls within the agreed survey scope.

Does all asbestos have to be removed before demolition?

HSE states that asbestos-containing materials should be removed, so far as reasonably practicable, before major demolition. The required work method and contractor depend on the asbestos material, condition and work involved.

Does all asbestos removal require a licensed contractor?

No. Asbestos work falls into different regulatory categories. Some work requires a licensed asbestos removal contractor while other asbestos work may be non-licensed or notifiable non-licensed work. The correct category must be established from the material and proposed work.

What happens if the demolition boundary changes?

The existing asbestos information should be reviewed against the new scope. Additional intrusive surveying may be required where previously unaffected parts of the building will now be demolished.

How much does a Demolition Asbestos Survey cost?

Smaller demolition surveys may start from around £320 plus VAT. Larger commercial, industrial or multi-building sites are priced according to building size, demolition boundary, access, intrusion, sampling and reporting requirements.

Are ASM Demolition Asbestos Surveys UKAS accredited?

Asbestos Surveying and Monitoring Ltd holds UKAS accreditation number 32982 for defined asbestos inspection activities to ISO/IEC 17020. Accreditation applies to the activities and locations detailed on ASM's current UKAS schedule.
