Planning Asbestos Removal Work

Once you are satisfied with the contents of the survey report the next step is to identify what asbestos materials need be removed. There are two variations of asbestos removal work that is dictated by the type and condition. This element would determine the controls that are required for the safe removal and disposal.

Legislation dictates how asbestos is removed, the HSE have set a limit that must never be exceeded without adequate controls. This is called a control limit and set at 0.1f/cc averaged over a 4 hour period.

There are two variations of asbestos removal works

  1. License Asbestos Removal Work for high risk asbestos containing materials these include: Asbestos Insulation Board – Thermal Insulation (lagging) – Sprayed Coating Insulation
  2. Non-License Asbestos Work for lower risk asbestos containing materials these include: Cement Products – Floor Tiles – Roofing Tiles/Slates – Textured Coating (Artex) – Eletrical Flash Guards – Bitumen – Bakerlight Plastics

Identifying the Correct Scope of Work

To ensure that your HSE licensed asbestos removal contractor provides an accurate cost you will have to provide a detailed scope of work and an asbestos survey report. The scope of work may include the following:

  • Security arrangements – requirement for security clearance and access to the site
  • Duration of work
  • Time constraints – following your programme of work
  • Working hours – potential weekend or operating 24/7
  • Welfare arrangements – is the work remote or can you use a shared facility
  • Safe storage of plant and equipment – including the location of the DCU, and hazardous waste container
  • Is the place of work occupied – arrangements of adequate controls
  • Health and safety considerations – ground conditions, fire, buried services, confined space or hot works
  • Site conditions – other contractors working in the same environment
  • Access arrangements – provisions for scaffolding or use of other access equipment.
  • Agreed KPIs
  • Client expatiations – following specific procedures
  • Site monitoring – consideration for site audits internally or externally
  • Provisions of air monitoring – appointment & duration of work

When undertaking high risk asbestos removal is it highly recommended that the licensed contractor visits the site and evaluates the working environment before any final cost can be agreed. Once you have nominated your preferred licensed contractor a site specific plan of work and risk assessments must to be prepared, therefore knowing the site conditions is a vital element for this process. The Licensed Contractor will also be required to notify the work to a regional HSE/EHO office 14 days before work can start. The work will also be subjected to an independent 4 stage clearance test, this would consist of close inspection of the controls and an air test to quantify the volume of potential airborne asbestos fibres. The test must be completed by an independent consultant that holds the provision for asbestos air testing UKAS 17025. On completion of the test the consultant will provide a certificate of re-occupation to the licensed contractor and client/building owner.
