This type of survey should be carried out prior to any refurbishment or demolition works. It is used to locate and describe, as far as is reasonably practicable all asbestos containing materials within the areas surveyed. This type of survey should normally only be conducted in unoccupied areas.
Fully Intrusive Inspection
The survey is fully intrusive and involves destructive inspection, as necessary, to gain access to all areas of the building fabric. A full sampling program will be undertaken to identify asbestos containing materials and estimates of quantity will be recorded. The survey is primarily designed to identify asbestos containing materials so that they can be removed in preparation for refurbishment or demolition.
The intrusive inspection techniques used in undertaking Refurbishment / Demolition Asbestos Surveys will cause damage to the fabric of the building being surveyed as all parts of the building fabric will need to be accessed to make a comprehensive assessment.
It should be noted that in some cases asbestos containing materials may be concealed within the fabric of a building which can only be positively identified once demolition has actually begun. Additional consultation/site visits may be required in such instances.
A Refurbishment / Demolition survey can be undertaken to specific areas of a building affected by proposed works, e.g. re-wiring, plumbing works.
A comprehensive report is produced detailing the location, condition, material assessment and recommendations for remediation of asbestos materials identified, including photographic records and annotated plans. This information can be used by Asbestos Removal Contractors to form the basis of tenders for Asbestos Removal, however a site visit by the contractor will still be required.
‘The survey must locate and identify all ACM’s 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.’ – HSE Managing Asbestos
