Refurbishment Asbestos Survey Derby — inspect the exact fabric your project will disturb
Investigate the exact building fabric the project will disturb
A Refurbishment Survey is designed around the specific alteration or refurbishment boundary and may require destructive access to hidden areas.
Walls & partitions
Openings, linings, boxing, risers, cavities and structural interfaces affected by the design.
Floors & ceilings
Floor finishes, screeds, voids, suspended ceilings, textured coatings and hidden layers.
Services & plant
M&E routes, ducts, service penetrations, plant replacement and associated fire-protection materials.
Investigate the complete Derby alteration route
A Refurbishment Survey addresses the building fabric affected by planned intrusive work. For Derby offices, commercial units and homes, the instruction should follow removed finishes, openings, drilling, floor preparation and the full routes of new services.
A scope based only on the room receiving new equipment may miss connections through retained areas. Provide current drawings and describe the depth of disturbance. Include landlord-controlled systems, external components and ancillary structures where the project reaches them.
The survey is intrusive and may need vacancy, service isolation and opening of concealed spaces. Agree permissions, safe access, the extent of damage to finishes and making-good responsibilities before the appointment. A short access window should not be mistaken for adequate opportunity to inspect every relevant element.
Review known construction phases and previous alterations. A modern fit-out can conceal earlier fabric, while a genuinely newer area may have reliable construction evidence. The investigation should use that information for the actual work rather than assuming the whole site shares one material history.
Keep the authorised survey drawing with the issued report. When the fit-out team receives a newer layout, compare the affected fabric against the recorded investigation before accepting the change. A drawing revision is a useful trigger for review even where the overall room area remains the same.
Send drawings and the specification, not just the building address
HSE requires the survey type and scope to match the work. A red-line plan, room schedule or description of the elements being altered helps ensure the intrusive inspection covers the intended disturbance.
See HSE survey guidance and ASM's UK Refurbishment Survey page.

Survey before disturbance, then define the asbestos work
Define refurbishment
Confirm the exact work area and elements affected.
Survey intrusively
Investigate the relevant building fabric under controlled conditions.
Scope ACM actions
Define removal, protection or design changes before disturbance.
Release the work area
Provide clear asbestos information for the next controlled project stage.
The survey result should feed straight into the project plan
Use the findings to decide whether removal, further testing, analytical support or a design change is required.
Removal
Where ACMs conflict with the works, obtain a comparable project-specific removal scope.
Air monitoring / clearance
Analytical support may be needed around removal or licensed enclosures depending on the work.
One additional material
Targeted sampling can resolve a newly exposed suspect material where a wider resurvey is not required.
Unexpected disturbance
Stop work, restrict further disturbance and assess the material and contamination before relying on an air test alone.
Survey the connections behind a Derby refurbishment
A new service through an occupied workshop
A replacement distribution board, heating supply or extraction system may require openings through floors, wall linings, fire stopping and roof components. Ask the designer to mark each penetration and connection point. Include enabling work needed to reach the installation, not just its finished position.
Agree who releases the area for intrusive inspection and who restores fire, weather and security protection after opening-up. Coordinate the survey before the installer commits to the route.
Retained frontage, new internal layout
An office or shop around Friar Gate may retain its external appearance while internal partitions, ceilings and services change substantially. Mark retained fabric and the exact alteration depth. Later linings and repairs can matter as much as the original construction.
Property-specific conservation advice and asbestos investigation should be coordinated at the design stage. A restriction that prevents inspection of disturbed fabric must remain a project action.
Release work areas and resolve interfaces before the fit-out starts
For a phased Derby office project, show each area to be vacated and the services connecting it to occupied space. The survey team needs to know who controls shared routes and who can authorise opening-up. An empty room is not necessarily isolated from adjoining use or plant.
Agree the access schedule, service isolations and any specialist support with the client. Clarify which party provides equipment and who reinstates finishes after intrusion. If the property includes protected fabric, obtain the necessary project advice and permissions for the proposed access approach.
Keep a record of the design revision investigated. Review architectural, electrical, mechanical and structural packages together so one trade’s connection through a retained area is not omitted from the scope. Identify any routes that cannot yet be accessed and the later investigation required.
After the report, review findings and limitations before issuing the work package. Define affected asbestos, the removal or protective measures required and any independent analytical appointment. A survey visit or individual sample result is not a completed release of the whole construction area.
During the work, an unexpected suspect material or new design route should trigger a pause in the affected disturbance and a scope review. Keep supplementary investigation with the original report so contractors and future managers can trace the evidence to the actual work carried out.
Information that makes the refurbishment brief workable
- Current drawings with demolition, removal and retained elements clearly distinguished.
- The specification for wall, floor, ceiling and roof work.
- Full electrical, plumbing, ventilation and other service routes.
- Work on external elevations, garages, plant or adjoining spaces.
- Existing surveys, registers, asbestos-removal records and any known restrictions.
- Access ownership, isolations, occupancy, opening-up and making-good arrangements.
If the design is incomplete, identify the uncertainty at quotation stage. A later extension of the works may need additional investigation and should be reflected in both the survey brief and the programme.
Release the work area for intrusive inspection
Agree vacant survey areas, segregation, safe access, service isolations and the authorised opening-up method. Intrusive inspection can damage finishes. The client and survey team should clarify who handles specialist access, isolations and reinstatement, together with how reoccupation will be confirmed.
On an occupied Derby industrial or commercial site, decide which phases can be released and which activities must stop. Do not programme contractors to begin disturbance before the survey findings, laboratory results and limitations have been reviewed.
The approach should follow HSG264 survey guidance and the specific conditions of the premises.
Check each work package against the same drawing revision
Refurbishment designs often develop after the first quotation. Keep the issued survey boundary linked to a dated drawing or specification and make sure all trades are working from the same information. A revised ventilation route or additional wall opening can take work outside the inspected scope even if the overall project name has not changed.
For a Derby office or industrial fit-out, review the electrical, mechanical, architectural and structural packages together. One trade may need access through a retained area to complete an installation in the refurbished room. That associated disturbance should be considered before the survey is closed out.
- Mark routes, openings, affected finishes and the expected depth of disturbance.
- Identify retained areas that provide access to the work or shared services.
- Record design changes and request a survey-scope review where needed.
- Keep limitations visible in tender and contractor information.
- Confirm that newly exposed suspect material triggers a review before further disturbance.
This coordination reduces the risk that each contractor assumes another package has already investigated a concealed area. The final report and any supplementary investigation should remain traceable to the actual works being released.
Use the findings before issuing the work package
Check that the report boundary matches the latest project drawings. Resolve uninspected areas before they are disturbed, identify asbestos affected by the works and define any removal or protective arrangements. Communicate the material locations and restrictions to the principal contractor and relevant trades.
ASM can support removal planning and analytical requirements where needed. Agree these as separate work packages with clear completion evidence. A survey report is not itself a removal completion document.
Use Derby survey costs to understand the budgeting factors for intrusive investigation.
Follow the layers a Derby contractor will actually disturb
Floors and internal finishes
Describe whether work removes a surface covering only, underlying adhesive, screed or deeper construction. Ceiling replacement may involve tiles, concealed boards, service boxing and supports above. A refurbishment survey should follow the relevant layers and interfaces within the work boundary. Provide the proposed method rather than assuming a room name identifies the depth of investigation.
Services and penetrations
For workshop upgrades, mark wall cores, cable routes, ventilation openings and roof connections. Fire stopping, older ducts and lining materials can sit beyond the footprint of the new equipment. Ask the designer and installer to agree the route before the instruction is fixed. A changed penetration later in the project should be compared with the inspected location.
Retained features and temporary works
Opening-up may affect finishes the client intends to retain, and enabling works can create their own disturbance. Identify temporary access openings, protective arrangements and making-good responsibilities. Where heritage or operational restrictions affect access, agree a practical investigation plan. Keep unresolved fabric identified until the work team has adequate evidence to address it.
An actionable contractor pack
Issue the report with the relevant drawing revision and a clear record of restrictions. Link sample results to material locations and identify required next actions. The contractor needs to understand which parts support its work and which still require investigation or asbestos work. Preserve the full report rather than extracting a sample schedule without its limitations.

Asbestos Refurbishment Survey Derby FAQs
Does a Derby plant upgrade require the machinery to be included in the survey?
Clarify whether the instruction covers building fabric, equipment or both. Identify the actual disturbed components and service interfaces, then agree competent investigation and any specialist access or isolation. A building survey should not be assumed to assess every internal machinery component.
How are protected features handled during a refurbishment survey?
Identify the features, permissions and access restrictions before attendance. Agree authorised opening-up and making good with the responsible parties. Heritage status does not remove the need for suitable asbestos information; any limitation affecting the work must be resolved or controlled before that disturbance proceeds.
Do I need a refurbishment survey for a rewire?
Where the work could disturb asbestos, information must adequately cover the affected fabric. Cable routes, consumer-unit work, penetrations and access openings should be included in the survey brief as appropriate.
Can a refurbishment survey cover only part of a building?
Yes. A defined part can be surveyed if it includes the complete disturbance boundary. Areas outside that boundary remain outside the report’s conclusions.
Will the survey damage finishes?
Intrusive inspection may require opening-up and damage to finishes. Agree access, permitted investigation methods and making-good responsibilities before the survey.
Can staff or residents remain in the survey area?
Intrusive refurbishment survey areas must be vacated. Agree segregation, access controls and suitability for reoccupation as part of planning the inspection.
What if the contractor changes the design afterwards?
Compare the revised work with the inspected boundary. New service routes, openings or deeper disturbance may require further survey work before the revised activity starts.
Can an old sample result replace the survey?
A result can contribute evidence for its material and location, but it does not establish that every affected component has been investigated. Review all existing information against the complete proposed work.
Can we use a room list instead of drawings?
A room list can help, but it may not describe the affected fabric, depth or service connections. Provide marked drawings or an equally clear written specification showing every route and opening that needs investigation.
What should the principal contractor check in the report?
Check the survey type, work boundary, drawing revision, material findings and restrictions against the construction scope. Arrange resolution of missing areas and any required asbestos work before the affected activity is released.
Send the work scope before the surveyor attends
Provide the address, drawings, marked work areas, specification, existing asbestos reports, access restrictions and programme. ASM can define the intrusive survey boundary and provide a written quotation.
