Introduction
ABC Construction were rewarded a contract to carry out a Refurbishment and Demolition of the local council building. Areas of the of the building are to be refurbished as part of a phased refurbishment at the council building.
Objectives
The objectives of this report were to:
Carry out a survey to ascertain the presence of asbestos based materials.

Carry out a survey to locate and describe, as far as reasonably practicable, all asbestos containing materials prior to refurbishment/demolition.

Gain access to all areas, as necessary, to determine the extent of any asbestos that may be present.

Estimate the extent and volume of any asbestos materials that may be present.

Produce a report identifying areas containing asbestos to be used as a basis for tendering their removal.

Instigate asbestos removal works prior to refurbishment/demolition.

Survey Limitations
All areas that will be accessed for the proposed refurbishment/demolition works were subjected to a refurbishment and demolition survey for asbestos containing materials (ACM’s). The investigation consisted of an inspection of each room and area that will be impacted by the works.

Survey Date
The Survey was carried out on 12th/October/2018 by Christopher Hearne (Environmental Health ; Safety Officer/Asbestos surveyor) of ABC Construction.

Scope of Work
The works will involve:
Upgrading of the heating system which will include removal of existing fittings and the installation of a new energy efficient underfloor heating system.
Complete demolition of existing boiler room located externally to the main building.

Removal and replacement of existing suspended ceilings to allow for installation of a new fire alarm system.

Removal of existing architrave and doors, and replacement with new.

Removal of existing windows, and replacement with new triple glazed windows.

Removal of existing textured finish to internal walls, and re-plastering of same.

Removal of existing roof, and replacement with new roof system.

demolition of walls and ceilings, removal of existing glazed elements and other ancillary works to remodel the existing layout.

Asbestos Refurbishment ; Demolition Survey
A refurbishment and demolition survey will be required before any refurbishment or demolition works begin. This type of survey is used to locate and describe, as far as reasonably practicable, all ACM’s (Asbestos containing materials) in the area where the works will take place. The survey will be fully intrusive and involve destructive inspection, as necessary, to gain access to all areas, including areas that prove difficult to access.

Where the refurbishment or demolition works may not take place for a significant period after the survey(e.g. three months), then the information required for a management survey should be obtained. (Kelleher, 2013)

Environmental and OSH hazards and risks associated with asbestos exposure including who may be affected.

Asbestos fibres can be very difficult to destroy in turn the body cannot break them down or remove them once they are lodged in the lung or in the body tissues. They remain in place where they can cause disease.

There are three primary diseases associated with asbestos exposure:
Asbestosis
Lung Cancer
Mesothelioma
ABC Construction shall not undertake any work which would expose or would be liable
to expose an employee to dust arising from either or both asbestos or materials containing asbestos unless:
A risk assessment determining whether asbestos or materials containing asbestos is present or is likely to be present in the work area
if there is doubt as to whether asbestos or materials containing asbestos is present in the work area ABC Construction shall assume that asbestos or materials containing asbestos is present, and comply with the provisions of Safety, Health and Welfare at Work (Exposure to Asbestos) Regulations 2006 .

Exposure limit value: The exposure limit value for asbestos is the maximum concentration of asbestos fibres in the air to which workers may be exposed at a place of work, measured or calculated with reference to an eight-hour period (i.e. the duration of an average work shift). The exposure limit value for all types of asbestos is 0.1 fibres per cubic centimetre of air (fibres per cm3) (equivalent to 100 fibres per litre of air). This exposure limit value is not a ‘safe threshold’. It is calculated that lung cancer mortality through forty-five years of exposure to 0.1 fibres per cm3 would amount to five additional deaths per thousand exposed people. (The Health and Safety Authority, Asbestos Guidelines)
Generally, a risk exists in demolition or refurbishment projects because there is a possibility of asbestos or asbestos containing materials in the work environment, this risk of exposure increases when an appropriate survey, to determine the type and quantity of any asbestos/asbestos containing materials has not been carried out by a trained and competent person.

Typical hazards that employees may be exposed too in areas containing asbestos or asbestos containing materials may include:
Lack of information/training provided to employees.

Inadequate facilities provided to employees to eat, drink and wash.

Asbestos or asbestos containing materials incorrectly sealed and labelled.

Asbestos dust accidently released into the surrounding atmosphere.
Inadequate personal protective equipment/respiratory protective equipment/protective clothing provided to employees who are likely to be in areas containing asbestos/asbestos containing materials.

Ease of access into areas containing asbestos/asbestos containing materials.

Possibility of asbestos or asbestos containing materials in the work environment.

Incorrect methods of storing and/or transporting asbestos containing materials.

ABC Construction as an employer shall –
Ensure employees are provided with information, instruction and training so they know the risks involved in their work and the precautions they should take, as required by the 2005 Safety, Health & Welfare at Work Act.

Ensure adequate facilities for employees to wash, eat and drink are provided.
Ensure employees are made aware of the results of any measurement of asbestos dust in the air in their work area.

Ensure the number of employees exposed or likely to be exposed to dust arising from either or both asbestos or asbestos containing materials is kept to the lowest possible number.

Ensure that systems of work are designed not to produce asbestos dust or, if that proves impossible, to avoid the release of asbestos dust into the air.

Ensure that asbestos or asbestos-containing materials are stored and transported in suitable sealed packing.

Ensure that waste is collected and removed from the place of work as soon as possible in suitable sealed packing with labels clearly indicating that it contains asbestos.

Ensure that relevant signage is displayed in areas where such activities will take place.
Ensure that appropriate and suitable protective clothing is provided to employees who will be in the area.

Ensure that protective clothing is worn correctly by employees in the area.

Ensure that any area containing or likely to contain asbestos/asbestos containing materials is not accessible to employees other than those who, by reason of their work duties, are required to enter such an area.

Ensure that employees only smoke in designated areas.
Ensure that, where exposure cannot reasonably be reduced by other means, employees are provided with appropriate individual respiratory protective equipment and ensure that it is worn correctly by those employees.

Ensure employees have received training in the correct use of respiratory protective equipment and personal protective equipment. ( The Health and Safety Authority)
Asbestos monitoring, exposure prevention and containment system requirements that should be used during the renovation project.

Where an initial examination reveals that the amount of asbestos fibres in the atmosphere at a place of work is equal to or greater than the exposure limit value, the measurement of asbestos in the air at the place of work shall be carried out on a regular basis throughout the duration of the project.

For the purposes of measuring asbestos in the air sampling shall be representative of the personal exposure of the employee to dust arising from asbestos or materials containing asbestos. Sampling shall be carried out by a competent person after the employer has consulted with the employees concerned.

When samples are taken they shall be analysed by a competent person, in accordance with the recommended method, in a laboratory suitable for fibre counting. The duration of sampling shall be such that representative exposure can be established for an eight-hour reference period (one shift) by means of measurements or time-weighted calculations. Fibre counting shall be carried out wherever possible by PCM (phase contrast microscope).
For measuring asbestos in the air only fibres with a length of more than 5 micrometres and a breadth of less than 3 micrometres and a length/breadth ratio greater than 3:1 shall be taken into consideration. (Safety, Health and Welfare at Work Asbestos Regulations 2006 -2010)
Specific asbestos waste management, packaging, labelling and shipment requirements that must be adhered to when sending the asbestos waste to a licenced waste disposal facility in Europe.

The removal and transportation of asbestos materials is subject to several statutory provisions including the Safety, Health and Welfare at Work (exposure to asbestos) Regulations 2006.It should be noted that a licensed asbestos contractor must notify the relevant authority of their intention to remove such items. Notification of such works is normally subject to a 14-day period.

The materials which may be transported under this special provision may be subdivided into friable and non-friable materials.

Friable materials:
Friable materials must be carried with UN approved packaging suitable for the
transport of asbestos. When such packaging is used, no other requirements of ADR apply. However, packages must be marked with an ‘a’ asbestos label in accordance with REACH(Registration, Evaluation, Authorisation and Restriction of Chemicals).

(as provided in Figure 1).

Examples of friable materials:
• Thermal insulation on pipe work and vessels
• Asbestos insulating board
• Mill board
• Textiles, ropes and paper
Non-friable materials:
It comes highly recommended that non-friable materials are double wrapped or double bagged in heavy duty plastic.

All openings should be completely sealed with suitable adhesive tape.

The package must be able to withstand normal handling and transport operations without opening or failing. When this is achieved there are no other ADR requirements.

However, as provided above in Figure 1, you must mark all packages with an ‘a’ asbestos label in
accordance with REACH
ins
Examples of non-friable material:
• Asbestos cement products in good condition
• ‘Galbestos’, which is bitumen layer on corrugated galvanized sheets
• Damp proof course
• Roofing felt
• Bitumen products (acoustic sink pads)
• Toilet cisterns
• Compressed gaskets in good condition
• Enclosed electrical fittings
• Putties, mastic and sealants
