Survey the area the work will disturb
A refurbishment asbestos survey is not a general inspection of the building. It must follow the proposed work. If contractors will open a riser, chase a wall, lift floor finishes, replace a ceiling, alter plant or break through an external panel, those locations need to sit inside the defined survey area.
The starting point is a marked-up plan and a clear schedule of work. Room names alone are rarely enough. We look for the actual routes, penetrations, voids, interfaces and fixed finishes that will be disturbed, including areas above ceilings, below floors, behind boxing and within service ducts.
Why a management survey is not enough
A management survey is intended to support normal occupation and routine maintenance. It does not usually involve the destructive access needed before refurbishment. Where work will disturb the fabric, HSE guidance in HSG264 identifies a refurbishment and demolition survey as the appropriate survey type for the affected area.
Regulation 5 of the Control of Asbestos Regulations 2012 requires employers to identify asbestos before work that may expose people to it, or to assume asbestos is present and apply the relevant controls. The survey therefore needs to be completed early enough for designers and contractors to use the findings in the construction plan.
What intrusive inspection looks like on site
In practice, the surveyor may need to lift carpet tiles and floor coverings, remove inspection sections from plasterboard or lath and plaster, open boxing, inspect service risers, enter ceiling and floor voids, and expose concealed structural or fire-protection materials. The opening-up should match the work, not stop at the easiest visible surface.
Buildings altered between the 1950s and late 1990s can contain several asbestos products within one work area. Common findings include asbestos insulating board to risers and fire breaks, sprayed coatings to structural steel, pipe insulation, textured coatings, vinyl floor tiles and bitumen adhesive, cement sheets, soffits, flues, gaskets and rope seals. Product age and appearance guide the inspection, but laboratory analysis is needed for positive identification.
Set the survey scope before access is booked
Send the proposed drawings and work schedule so we can identify the rooms, voids, service routes and external elements that need intrusive inspection. We are an independent consultancy: survey, sampling and removal work is carried out by the vetted professionals we appoint.
Vacant areas, isolations and enabling work
The work area should normally be vacant while destructive inspection is carried out. Surveyors need safe access, enough time to open the construction, and authority to enter locked or controlled spaces. Stored goods, fitted furniture and plant can prevent a complete inspection if they are not dealt with before the visit.
Electrical, gas, water and mechanical services may need to be isolated by competent persons. Access equipment may be required for high-level panels, roofs, ducts or soffits. In occupied buildings, the survey plan should also address segregation, dust control, noise and the safe condition in which opened surfaces will be left.
Limitations must be specific
A refurbishment survey should remove uncertainty from the defined work area, but genuine access restrictions can remain. Every uninspected location should be identified on the plan, explained in the report and treated as containing asbestos until further inspection proves otherwise.
Vague statements such as “areas may be inaccessible” are not good enough. A useful limitation names the exact ceiling void, riser, floor zone or wall construction, records why it could not be entered and sets a hold point before work reaches it. Phased projects often need a return inspection after scaffold erection, service isolation or an initial strip-out exposes the next layer.
Sampling, analysis and presumptions
Representative samples should be taken from suspect materials where it is safe and appropriate to do so. Analysis should be completed by a laboratory accredited by UKAS to ISO/IEC 17025 for asbestos identification. Where a material cannot be sampled, the report should state whether it is presumed or strongly presumed to contain asbestos and the project team should manage it on that basis.
Sampling needs judgement. A large run of apparently similar board, insulation or floor finish may include repairs or later additions, so the surveyor should consider changes in colour, thickness, fixing pattern and installation date rather than relying on one convenient sample.
Making good after destructive access
Intrusive inspection leaves openings. Before the survey, agree whether the surveyor will make areas temporarily safe or provide full reinstatement. Temporary work may include sealing an opening, replacing a ceiling tile or boarding a small access point. It may not include decorating, specialist fire stopping, weatherproofing or matching an existing finish.
Where fire compartmentation, security or weather resistance could be affected, the required standard of reinstatement should be written into the survey plan. This avoids a completed inspection leaving the building in an unacceptable condition.
What the report must give the project team
The report should map the location and extent of each identified or presumed asbestos-containing material within the work area. It should include photographs, sample references, laboratory results, material descriptions, access limitations and any locations requiring further inspection.
Designers and contractors should be able to compare the report directly with the drawings and work sequence. The findings then inform removal decisions, risk assessments and plans of work. The report is not a clearance certificate, a removal method statement or permission to start work without the remaining project controls.
Checks before refurbishment starts
- Confirm that the survey boundary matches the latest drawings and work package.
- Check that ceiling voids, floor voids, risers, ducts, plant enclosures and external elements affected by the work were inspected.
- Read every limitation and place a hold point before work reaches an uninspected location.
- Match plans, photographs and sample references to the actual site.
- Confirm that sampled materials have laboratory results and that presumed materials are clearly marked.
- Verify the survey organisation’s competence and the current scope of any claimed accreditation.
- Agree how identified asbestos will be removed or controlled before the relevant work begins.
Arrange the inspection before the programme is fixed
Early survey access gives the design team time to deal with asbestos findings without forcing decisions after contractors have started opening the building.
Frequently asked questions
Do I need a refurbishment survey if I have a management survey?
Yes, where the planned work will disturb the building fabric. A management survey supports normal occupation and routine maintenance; it is not normally intrusive enough for refurbishment work.
Does the survey have to cover the whole building?
Not necessarily. It should cover the full area affected by the planned work, including hidden voids, service routes and adjoining construction that will be disturbed. Areas outside the defined scope are not cleared for work.
Can refurbishment continue if part of the area was inaccessible?
Work should not enter an uninspected location. The report should identify the limitation and set a hold point for further inspection before that part of the project proceeds.
Who repairs damage caused by the survey?
That should be agreed before the inspection. The survey plan should state whether openings will be made temporarily safe or fully reinstated, including any fire stopping, weatherproofing, security or decorative requirements.
