6 Page 6 of 24 Site Description General Information: Maylarch Environmental Surveying were instructed by Louise Reilly of Vale of White Horse District Council. to conduct an Asbestos Management Survey at Chapel Way Public Toilets, Botley This was a commercial site and comprised of a brick built public. The Survey was conducted by Dean Jeffs (Lead Surveyor) of Maylarch and this was undertaken on the 22nd November It should be noted that a management survey is NOT destructive but some intrusive inspections may have been carried out; however this survey should not be used to undertake any refurbishment or demolition works. Where safe to do so, all areas were inspected to locate, as reasonably practicable asbestos containing materials (ACM s). Any areas that have been excluded/restricted at the clients request are outlined in section 3 (Caveat). This survey forms the basis of your written Management Plan which you require to comply with Regulation 4 of the Control of Asbestos Regulations (CAR) Any person undertaking work within the buildings should be told of the presence of asbestos. This briefing also applies to any other person associated with the site, including staff, subcontractors and others. It is strongly recommended that this report is reviewed prior to any change of use, occupancy or any other activity which may affect the accessibility of any materials within the areas surveyed. It is recommended that all asbestos material identified is inspected at least annually to assess condition and likelihood of disturbance. Such reviews should only be conducted by a competent person. The client is advised not to solely read the asbestos register as a definitive description of all ACM s within the building. This survey was undertaken in line with our UKAS accreditation for inspection bodies (ISO/IEC 17020:1998). However any comments or recommendations are outside the scope of accreditation. THIS REPORT SHOULD BE READ IN ITS ENTIRETY. Questions arising from this report should be directed, in the first instance, to the author of this report, who will be pleased to clarify any technical issues or concerns raised. The table below details whether rooms have been accessed or not whether they are suspected of containing Asbestos or not. NB: If a room has not been fully accessed then it is classed as not accessed.

8 Page 8 of 24 Survey Technique This survey was undertaken in line with HSG 264; Asbestos; The Survey Guide, and involved collecting and analysing representative samples from any suspected Asbestos Containing Materials (ACMs) and recording the type, condition, quantity and location of these materials throughout the building. This type of survey is essentially intrusive without being destructive. Materials of a similar type were only occasionally sampled and it was assumed that other surfaces identical to where the sample was taken, was of a similar composition. Photographs were taken at all of the sample locations (unless otherwise stated). Rooms have been re-numbered by Maylarch for the purpose of this report. Material assessments have been compiled from the information obtained on site during the survey. It is the clients responsibility to complete the priority risk assessment. In line with the current legislation Maylarch provides an independent analytical report from a UKAS accredited laboratory to UKAS Standard ISO All Asbestos Bulk Sample Analysis is conducted by using Polarised Light and Dispersion Staining Techniques. Dispersion Staining is used to describe the colour effects produced when a transparent colourless particle or fibre is immersed in a liquid having a refractive index near to that of the particle or fibre, and is viewed under a microscope using transmitted white light (based on HSE Publication HSG 248).

10 Page 10 of 24 Survey Caveat 1 The following areas/ items below were not inspected during the survey as agreed with the client/ instructing party from the information gathered at the enquiry stage and highlighted within our quotation. The client did not hold any electronic floor plans, therefore the surveyors will complete a sketch on site. Damage will be limited to small nicks and scrapes to the internal and external surfaces of the property. There were no lifts within the scope of works, therefore no provisions were made by Maylarch to access any lifts or associated shafts. The property was live, occupied and was not possible to isolate the electrics during the survey. Therefore any electrical units or machinery that in our surveyors opinion could of contained asbestos will have been highlighted in the survey report as presumed to contain asbestos until proven otherwise. The client was unaware of any known asbestos within the survey scope, therefore no provisions were made to access behind any asbestos containing materials. The client did not require any air monitoring to be carried out during or after the survey, therefore no provisions were included for this service. The client confirmed that there areas both internally and externally greater than three metres in height. However these are not required to be physically inspected but visually noted. 2 It is however known that asbestos materials are frequently concealed within the fabric of the building or sealed voids or may have been used in a concealed composite and sometimes used in a random or ad-hoc manner. As such they may only be revealed during refurbishment or demolition of those areas. Client Name: Vale of White Horse District Council Site Address: Chapel Way.

12 Page 12 of 24 Survey Recommendations 1 Material Assessment and Algorithm The material assessment is an assessment of the condition of the ACM, or the presumed ACM, and the likelihood of it releasing fibres in the event of it being disturbed in some way. This material assessment will give a good initial guide to the priority for management, as it will identify the materials, which will most readily release airborne fibres if disturbed. HSG 264 recommends the use of an algorithm to carry out the material assessment, and contains an example. The algorithm is a numerical way of taking into account several influencing factors, giving each factor considered a score. These scores can then be totalled to give a material assessment score. The use of algorithms is not infallible, but the assessment process is clear for all to see, so if discrepancies arise, it should be possible to track back through the assessment process to find the root of the error. The algorithm shown in HSG 264 considers four parameters that determine the risk from ACM: that is the ability to release fibres if disturbed. These four parameters are: Product type; Extent of damage; Surface treatment; and Asbestos type Each of the parameters is scored and added to give a total score between 2 and 12: Materials with scores of 10 or more should be regarded as high risk with a significant potential to release fibres if disturbed; Those with a score between 7 and 9 are regarded as medium risk; Materials with a score between 5 and 6 are low risk; and Scores of 4 or less are very low risk. THE MATERIAL ASSESSMENT LOOKS AT THE TYPE AND CONDITION OF THE ACM AND THE EASE WITH WHICH IT WILL RELEASE FIBRES IF DISTURBED. THE PRIORITY ASSESSMENT WHOS RESPONSIBILITY LIES WITH THE DUTY HOLDER LOOKS AT THE LIKELIHOOD OF SOMEONE DISTURBING THE ACM. 2 The recommendations/actions set out in this report are Maylarch recommendations only and should be reviewed by the person/s responsible for managing the Asbestos Containing Materials (ACM's) identified. All ACM's should be removed prior to any Demolition / Refurbishment / Disturbance. Some ACM's require an asbestos licence to be removed and these materials will need to be removed by a licensed asbestos removal contractor. These materials are subject to a 14 day notification period to the Heath & Safety Executive (HSE). If the ACM's do not require a licence to be removed then they must be removed in accordance with the Control of Asbestos Regulations (CAR) 2012 and all relevant insurances must be in place. We strongly recommend that you seek advice if you are unsure as to which materials require a licence and which do not. Client Name: Vale of White Horse District Council Site Address: Chapel Way.

14 Page 14 of 24 Chapel Way Public Toilets, Botley Executive Summary A Management Asbestos Survey was carried out at Chapel Way Public Toilets, Botley on 22nd November 2012 by Dean Jeffs of Maylarch Environmental Ltd. Below is a short brief of our findings. Internals No asbestos containing materials were located during the survey. Externals No asbestos containing materials were located during the survey. Restricted/No Access Areas Room 0.4 was not accessed due to keys not available at time of survey. If any refurbishment or demolition works are to be undertaken in the future, it is highly recommended that a refurbishment/ demolition survey is carried out prior to any works commencing. It is also advised that the survey is undertaken at least 6 weeks prior to any works commencing to assist in planning the project(s) and for any licensed asbestos removal works to be notified.

17 Page 17 of 24 R or R Referred Sample: SP or SP Strongly Presumed Sample: P Presumed Sample: V Visual Inspection: Definitions When the Surveyor identifies several areas of materials that are the same, he may decide to sample one area and refer all other areas to this sample. This applies to samples taken on the same floor, samples are not usually referred across different floors in a building. The referred samples must be clearly marked on the site drawings using the same number as the original sample with the letter R after (e.g. 02R). The surveyor may make a separate material inspection that relates to a previous sample, (of the same type and material), without actually taking a sample if confident the material is the same. The surveyor will Strongly Presume the sample and there must be a separate material inspection record referencing the original sample. The sample number will have the letters SP after (e.g. 02SP). If part of an area being surveyed is not accessible to the surveyor or it is deemed unsafe to take a sample, in the case of live electrical gear etc. The surveyor will Presume that asbestos containing materials are present and note on the Material Inspection Sheets the type of asbestos presumed, the extent and that further investigation is needed before the presumption can be removed. The surveyor may make several visual inspections during a survey. This is where no physical sample was needed, but to verify this, a visual inspection was required, e.g. for voids, boxing, pipework under MMMF etc. For these inspections a separate material inspection record must be completed and the inspection number will have the letter V after (e.g. 02V).
