Asbestos Management Survey

This is the standard asbestos survey that should be carried out for the continued management of asbestos in premises. The purpose of the survey is to locate, as far as reasonably practicable, the presence and extent of any suspect ACMs in the building and assess their condition.
Although sampling is the most common approach that has been used for surveys, an asbestos management survey can also involve presuming the presence of asbestos.

An asbestos management survey can therefore be completed, using a combination of sampling ACMs and presumed ACMs or, indeed, just presuming. Any materials presumed to contain asbestos must also have their condition assessed (i.e. material assessment).

Asbestos management surveys may involve minor intrusive work and some disturbance. The extent of intrusion will vary between premises and depends on what is reasonably practicable for individual properties - agreement on this aspect of the survey should be reached between the client/duty holder and the surveyor. Factors that can affect the extent of intrusion include the type of building, the nature of construction, accessibility etc.

Refurbishment and Demolition Surveys

This survey is used to locate and describe, as far as reasonably practicable, all ACMs in the area where the refurbishment work will take place or in the whole building if demolition is planned. The survey will involve destructive inspections as necessary, to gain access to all locations, including those that may be difficult to reach. Refurbishment work may vary from relatively small to large projects. Small-scale work may occur in different parts of a building at different times over several years. A full asbestos sampling programmed is undertaken in these areas to identify possible ACMs and obtain estimates of the volume and surface area of the ACMs present. The survey is primarily designed to identify ACMs so that they can be removed in preparation for the refurbishment or demolition. Some advice is offered in the types of ACMs that is permissible not to have removed prior to demolition.

It is possible to use the two survey types in different parts of a building particularly where refurbishment work is in a limited area. Due to the intrusive nature of refurbishment and demolition surveys, it is recommended that the areas to be surveyed should not be occupied at the time of the asbestos survey taking place.

Rovin Environmental can undertake both management and refurbishment/demolition asbestos surveys on behalf of clients. Our surveys are performed by senior managers with at least 30 years' experience of working in the asbestos industry. Surveys are carried out in accordance with HSE standard HSG 264 Asbestos; The Surveyor's Guide.

Bulk Analysis

A representative sample of the material, suspected to contain asbestos is collected during the survey.

In the analytical laboratory of one of the Independent Analytical companies, this is visually examined, followed by a more detailed examination by stereomicroscope. One or more representative sub samples are prepared mechanically and or chemically for further examination. Fibres observed in the course of examination are categorized tentatively on the basis of morphology and certain physical properties. Each fibre type recognised is sampled by selecting a few fibres or bundles and these are mounted in a refractive index liquid to match the most likely asbestos type. The fibres are then positively identified as one of the six regulated types on the basis of their detailed optical properties using polarised light microscopy.

Asbestos Statutory Re-inspections

Additionally, Rovin Environmental qualified surveyors will perform a thorough visual inspection of the asbestos containing materials identified in the asbestos register in accordance with ACoP L127. Risk changes are recorded and the management plan updated. Recommendations for new control measures are given where required.

Rovin Environmental experienced asbestos surveyors all have over 15 years experience carrying out asbestos surveys, which will generally be a management sampling survey as defined in HSG 264 "Surveying, sampling and assessment of asbestos containing materials".

Case Studies


  •  As part of major refurbishment works, Rovin Environmental was contracted by BSD Ltd for asbestos removal and decontamination

     As part of major refurbishment works, Rovin Environmental was contracted by BSD Ltd for asbestos removal and decontamination works at The Swallow Hotel in Gateshead.

    The works consisted of the removal and disposal of asbestos insulation board cladding from the service risers in the bathrooms of each room and also the decontamination of the boiler room within the hotel. This work was vital to be completed before any refurbishment works could commence on each floor of the property.

    Rovin Environmental cooperated with the building contractors on site and communicated with them once a floor had been completed and had passed air clearances from an independent analytical company.

    Due to the state of which the hotel was in prior to refurbishment and asbestos works were carried out, Rovin Environmental liaised with BSD Ltd and procured extra works to clear floors with asbestos containing debris.

    Rovin Environmental was contracted to carry out the removal of all asbestos containing material in the soffits, undercloaks, and canopies to enable John Flowers Ltd to carry out refurbishment and replacement work on approximately 200 houses on the West Denton housing estate in Newcastle-Upon Tyne.

    Problems to resolve included tenants continuing to occupy the properties whilst work was being carried out, this issue was resolved by Rovin Environmental carefully planning the programmes of work to ensure the tenants suffered as little inconvenience as possible.

    Co-ordinating the Rovin Environmental programme with the client and scaffolding contractor has enabled Rovin Environmental to meet the client's strict delivery programmes on time.

    After the school had closed, Hartlepool Borough Council; had begun major refurbishment work in late 2013. Rovin Environmental were contacted

    After the school had closed, Hartlepool Borough Council; had begun major refurbishment work in late 2013. Rovin Environmental were contacted by Hartlepool Borough Council in early 2014 after it was found that asbestos containing materials had been inadvertently disturbed by tradesmen as he materials had not been found in the asbestos survey or were not identified correctly in the survey report and plans.
    The existing old type 2, or management type asbestos survey was found to be inaccurate and did not provide sufficient information for the planned works to proceed safely, and so it was agreed that Rovin Environmental would carry out a refurbishment/demolition survey of the building in order to provide the necessary information to meet the requirements of the CDM regulations.
    The survey revealed that a number of asbestos containing materials had been for whatever reason omitted from original, possible due to lack of access or incorrect labelling of sample locations in what was undoubtedly a complex site. Some of these asbestos materials needed to be removed in order for the refurbishment work to be carried out safely. These included asbestos insulation board ceiling and also chrysolite paper insulation to pipework in under floor ducts and risers.

    Rovin Environmental worked with Hartlepool Borough Council to agree a programme where the removal of the asbestos materials could be notified in accordance with the CAR 2012 but also to minimise disruption to the timescales for the refurbishment. The management of Hartlepool Borough Council were very appreciative of the assistance of Rovin Environmental in acting as consultants on the project and in helping to keep the project on time.

  • Rovin Environmental delivers key stages of refurbishment work at Brighton General Hospital for the National Health Trust.

    Rovin Environmental delivers key stages of refurbishment work at Brighton General Hospital for the National Health Trust.

    Rovin Environmental were awarded the contract to remove asbestos insulation board ceilings and asbestos containing pipework insulation from the kitchen and other areas of Brighton General Hospital prior to major refurbishment of this vital part of the building.

    This was a key phase of the planned refurbishment as the rest of the programme depended on the asbestos removal being completed on time. Rovin Environmental not only completed the work on time and on budget, but also worked with the client and other parties to include the removal of other asbestos containing materials extra to the original scope of works without extending the timescales, which could have delayed the project significantly.

    Rovin Environmental was appointed by a Local Authority to remove asbestos ceiling tiles from the kitchen and kitchen canopy of a school in Hartlepool during the October half-term holidays in 2013.
    The work was planned to allow the kitchen to be refurbished and have all the work completed in time for the school to reopen for the new term.

    After the removal work had commenced, the client approached Rovin Environmental and asked if it would be possible to amend the scope of works to allow the removal of the partition walls containing asbestos material. Rovin Environmental management discussed in detail with the client how the extra work could be accommodated without extending the timescale and delaying the reopening of the school.
    After informing the HSE, Rovin Environmental put into effect the amended method statement and completed the required work on time and on budget.

    Our client was very pleased with the high standards of work and the cleanliness of the area when it was returned for reoccupation. The commitment of Rovin Environmental management and staff who showed through their willingness to cooperate with the client, that they could bring projects to a successful completion safely.
