Asbestos survey competence before demolition

Before a building is demolished, a refurbishment and demolition asbestos survey has to be carried out, and it has to be carried out by someone competent to do it. The duty comes from regulation 5 of the Control of Asbestos Regulations 2012, which requires anyone proposing work that may disturb the fabric of a building to take reasonable steps to find out whether asbestos is present. A management survey will not do. The asbestos survey before demolition has to be fully intrusive, and that single difference drives the access, the programme and the cost.

Survey types and which applies

Two survey types are recognised in the guidance that sits behind the regulations, and they have different purposes.

A management survey locates asbestos that could be disturbed during normal occupation and maintenance. It is non-destructive, it presumes the presence of material in areas that cannot be reached, and it exists to support an asbestos register and management plan for an occupied building.

A refurbishment and demolition survey locates all asbestos-containing material in the area affected, so that it can be removed before the work starts. It is intrusive and destructive by design, it requires access into voids, ducts, roof spaces, wall build-ups and under floors, and it is carried out with the area unoccupied.

A management survey offered for a demolition project is the most common failure in this area. It is not a lower-cost version of the right survey. It is a document that answers a different question, and using it will leave undiscovered material to be found by a demolition contractor.

Accreditation and competence requirements

Competence here has a formal shape rather than being a matter of judgement.

The regulator's position is that surveys should be carried out by an organisation accredited as an inspection body, or by a surveyor holding a recognised personnel certification for asbestos surveying, working to a documented quality system. Separately, the laboratory analysing the samples should be accredited for testing, and the analyst carrying out air monitoring and four-stage clearance should be accredited for that work.

Ask for three documents before appointment: the accreditation certificate with its scope, the individual surveyor's certification, and the laboratory's testing accreditation. A firm that holds surveying accreditation does not necessarily hold analytical accreditation, and on a demolition project you will need both.

Insurance matters here more than on most surveys, because the consequence of a missed material is a stopped site and a notifiable incident. Check the limit of indemnity against the value of the works rather than against the survey fee. As our note on why every planning report needs a named author and date sets out, an unsigned report is a problem waiting to surface.

Access and destructive inspection

Access is the practical obstacle on almost every project, and it is worth resolving before the survey is commissioned.

The surveyor needs to open up the fabric: lift floor coverings, cut into partitions, remove ceiling tiles, open service risers and get into the roof void. In an occupied or part-occupied building that cannot be done safely or completely, which means either vacating the building or accepting a survey with recorded limitations.

Recorded limitations are the thing to watch. A survey that lists five inaccessible areas and presumes asbestos in each is honest and useful, and it also means the demolition contractor will encounter those areas on site. Where an area cannot be reached before vacant possession, plan a supplementary survey into the programme rather than hoping.

What the report must contain

A usable survey report gives the surveyor and the organisation, the accreditation reference, the date and the scope, a plan-based schedule of every sample location with a reference number, the laboratory analysis certificates, a material and priority assessment for each item, a schedule of presumed materials with the reason, and a clear statement of limitations.

Two things are commonly missing. The first is drawings that tie each sample reference to a location, which is what the removal contractor actually works from. The second is an explicit statement of which parts of the building the survey covers, which becomes important when a scheme is phased.

Treat the report as a construction document rather than a compliance file. It will be read by a removal contractor, a demolition contractor, the principal designer and the regulator.

Licensed removal and notification

Not all asbestos work needs a licensed contractor, and the categories matter to the programme.

Higher-risk work, which includes most work on sprayed coatings, lagging and certain insulating board, requires a contractor holding a licence from the regulator, and notification to the regulator a set period in advance of starting. Other work falls into notifiable non-licensed work, with its own notification, medical surveillance and record-keeping requirements, or into non-licensed work.

The notification period is the item that catches programmes. It runs before the work starts, not before the contractor is appointed, so a late survey compresses the notification into time that does not exist. Asbestos waste is hazardous waste and needs consignment notes and a permitted receiving site, which is a separate set of paperwork again.

Where the planning condition interacts

Asbestos is not a planning matter, and planning conditions touch it indirectly through three routes.

A demolition method statement or Construction Management Plan condition will usually require the sequence, the hoarding, the dust suppression and the wheel washing to be approved, and asbestos removal sits inside that sequence. A condition requiring a pre-demolition audit of materials for reuse interacts directly, because the Pre-redevelopment Audit has to record what cannot be reused as well as what can. And a condition on recording a building of interest requires the record to be made before strip-out, which competes with the asbestos removal for the same window.

Separately, section 80 of the Building Act 1984 requires notice of intended demolition to the local authority, and the counter-notice can impose requirements about shoring and services. That is a building control matter running alongside the planning position.

Programme and sequencing

Sequence the work in this order and the programme holds.

1. Obtain existing asbestos records and the asbestos register for the building under the duty to manage.
2. Commission the refurbishment and demolition survey as early as access allows, with limitations recorded.
3. Complete the pre-demolition materials audit using the same access visit where possible.
4. Complete any building recording required by condition before removal disturbs the fabric.
5. Appoint the removal contractor and allow the full notification period.
6. Carry out removal, air monitoring and four-stage clearance, with certificates retained.
7. Issue the clearance certificates to the demolition contractor before demolition starts.
