Asbestos Surveying


Marsh and Riddell surveyors are accredited through BOHS (British Occupational Hygiene Society) and hold P402 qualifications to carry out Asbestos surveys and bulk sampling of Asbestos Containing Materials (ACMs).

Management Survey

The purpose of the management survey is to manage Asbestos Containing Materials (ACMs) during the normal occupation and use of premises.

A Management Survey aims to ensure that:

  1. Nobody is harmed by the continuing presence of ACMs in the premises or equipment
  2. That the ACMs remain in good condition
  3. That nobody disturbs it accidentally

The Survey will locate any ACMs that could be damaged or disturbed by normal activities, by foreseeable maintenance, or by installing new equipment. It involves minor intrusion and minor asbestos disturbance to make a Materials Assessment. This shows the ability of the ACM, if disturbed, to release fibres into the air. It guides the client, e.g. in prioritising any remedial work that may be required.

The report will state the asbestos type, location, extent, condition and any surface treatment - the 'Materials assessment'. The report will also comment on priorities for any remedial work.

Refurbishment & Demolition Survey

The Refurbishment & Demolition Survey is required where the premises, or part of it, need upgrading, refurbishment or demolition. It aims to ensure that:

  1. Nobody will be harmed by work on ACM in the premises or equipment.
  2. Such work will be done by the right contractor in the right way.

The Survey will locate and identify all ACMs before any structural work begins at a stated location or on stated equipment at the premises. It involves destructive inspection and asbestos disturbance. The area surveyed must be vacated, and certified 'fit for reoccupation' after the survey.
