2.0 Contract Review:

Page 7 of 36 J023101

Inspectas Compliance Ltd received an order of confirmation to undertake a Refurbishment Survey from T & D Barrs. This order has been accepted on the basis of the original quotation and our terms and conditions of business.

The order relates to a Refurbishment Survey of:

Site Address Building Designation Building Description Age of building

London

12 Creswell Gardens Residential Circa 1900s

General Building Construction Type *Individual room construction can be found within Appendix 3 of this report

Three storey brick building

The survey was carried out by John Arnold.

The Type of survey selected / requested by the client was a Refurbishment Survey.

The reason for selecting this survey is to enable the client to identify asbestos in his premises so that it can be removed prior to major refurbishment

This survey was carried out in accordance with documented in house procedures, which are based on the HSE Guidance document HSG 264.

Purpose of Survey

The purpose of this Major Refurbishment Survey is to help the duty holder identify asbestos in these premises, prior to major refurbishment. It provides sufficient information to help the tendering process for removal works prior to any work starting. However it is strongly recommended that any asbestos removal should be undertaken against a detailed specification. We further recommend the appointed removal contractor should attend the site to confirm for themselves the quantities and location of asbestos to be removed, prior to costing.

Aim of Survey

The aim of the survey was to;

1. Locate and record the location, extent, and product type as far as reasonably practicable of known or presumed ACM’s.

2. Inspect and record information on the accessibility, condition and surface treatment of know or presumed ACM’s

3. Determine and record the asbestos type based on sampling or by making a presumption based on product type and appearance

4. Locate all ACM's within the fabric of the building prior to refurbishment.

3.0 Introduction/Objectives:

Page 8 of 36 J023101

3.4 Type of Survey – Refurbishment Survey

The purpose of this major refurbishment survey is to identify ACM’s to be removed prior to any major refurbishment work being carried out. This type of survey is used to locate and describe as far as is reasonably practicable all ACM’s in the whole building if major refurbishment is planned.

Major refurbishment surveys are intended to locate all asbestos within the building. It is a disruptive, fully intrusive survey that involves destructive inspection techniques that penetrate the building structure extensively. This involves breaking into floors, through walls, into wall voids ceilings, cladding, boxing, as necessary to gain access to all areas, including the inner fabric of the building. A full sampling programme is undertaken to identify possible ACM's and estimate their quantities.

The survey is designed to be used to help the tendering process, and should be used to start generating a specification for tendering the removal of ACM’s from the building prior to major refurbishment.

Whilst all asbestos materials have been identified as far as is reasonably practicable, some asbestos materials may remain unidentified buried within the fabric of the building during the survey. Asbestos shuttering buried within concrete slabs, asbestos hidden by structural supports, asbestos hidden behind other asbestos products, and building structures which are unsafe to fully access are potential locations.

It must be presumed that asbestos may remain unidentified to these type of areas and if suspect materials are uncovered during major refurbishment then samples should be taken for analysis.

- Type of Survey

Page 9 of 36 J023101

4.1 Details of information requested from the Duty Holder by Inspectas Compliance Ltd in order to carry out a desk top review and plan the survey in accordance with HSG 264 were recorded on our pre-survey questionnaire, along with details of all the information that were provided by Alison Temple on behalf of the client.

The Information provided was assessed during the desktop review and a survey plan, and risk assessment was produced for the survey of:

The survey was carried out to Refurbishment survey to property prior to interior decoration works and roofing works. Limited intrusive inspections made as not all areas of the building are being disturbed. .

Where information was provided regarding the presence of known or presumed asbestos materials then this has been validated during the course of the survey, and recorded within this report.

Detailed drawing were not provided by the client at the time of the survey.

A decontamination unit was not needed onsite during the survey.

Utilities and services were still live at the time of the survey.

Access equipment for working at heights was not required.

The survey did not involve confined space working.

The client did not inform Inspectas of any chemical/biological hazards.

No previous asbestos information was made available to Inspectas prior to survey works.

The following exclusions were agreed at the time of the survey on site:

No exclusions agreed

4.0 Desk Top Review and Survey Planning:

Page 10 of 36 J023101

This survey has been undertaken in accordance with HSG264 and Inspectas Compliance Ltd in house procedures.

Clients of Inspectas Compliance Ltd that have signed our terms and conditions are deemed to have agreed, and accepted, our surveying approach, our sampling strategy, and our standard planning, surveying and reporting format unless they have made specific requests to the contrary.

The information provided by the client or their representative are recorded in the planning document and has been used to define the scope of the survey.

Photographs of suspected ACM's will be taken at the time of the survey unless the client expressly requests otherwise. Sampling points and suspected ACM's will not be identified with labels unless the client expressly requests otherwise.

All fibrous materials and item will be included in the survey unless, in the surveyors professional opinion, these items can be excluded (eg. Wood, wallpaper, man-made mineral fibre). Samples of all thermoplastic floor coverings will be taken unless, in the surveyors professional opinion, such items can be excluded. All textured coatings and novel bituminous will be sampled.

Areas that could not be accessed were presumed to have ACM's present until proven otherwise. Each area requiring further inspection is documented within the Executive summary (Inaccessible areas). Inaccessible areas are also shown on the plan drawings (Appendix 5)

Materials that could not be accessed and in the surveyors opinion can be dismissed will be presumed to be ACM unless proven otherwise. Materials that are not sampled but, in the surveyors opinion, have a similar appearance, location and function as a previously sampled material will be strongly presumed to be similar to the sampled material.

The quantity of samples taken may have been minimised by using 'strongly presumed' as defined above. Materials that are 'strongly presumed' to be similar to a material that has already been sampled will be recorded in the comments section of the survey and referenced against the original sampled material.

Intrusive damage that is required to gain access to an area/location that is within the scope of the survey has been agreed with the client or the clients representative. Any control measures will be put in place before such action is attempted. If control measures cannot be arranged, no attempt to access the area will be made and the reasons recorded. The area/location will be presumed to have ACM's present until proven otherwise.

Non fibrous materials and item known not to contain asbestos (eg Breeze block, plaster, plasterboard plastics and non textured paints) will be excluded from the survey unless the surveyor suspects that these materials have been contaminated with asbestos from other sources or specifically requested by the client.

Older electrical equipment, which cannot be shown to contain ACM's, has been presumed to have ACM's present unless, in the surveyors professional opinion, such items can be excluded.

5.0 Survey Method

Page 11 of 36 J023101

6.1 For safety reasons it is not possible to inspect internal areas of plant and machinery.

During the course of the survey any areas not accessed, are detailed within the Data Sheets of this report, along with a comment on the reason for non access. Asbestos has been presumed to be present until further inspection and sampling to these areas proves otherwise

Residual asbestos material may be present beneath re-lagged services and cannot be detected unless the re-lagging is systematically removed. Caution should therefore be taken when working on such materials for the potential presence of asbestos residue.

Textured Coatings such as “Artex” may contain a trace quantity of Chrysotile asbestos. Due to this low asbestos content, applications of this product may be non-homogenous and may elicit both positive and negative samples. Where both positive and negative samples are obtained the client should presume that the textured coating contains Chrysotile throughout even though a non-detected result has been obtained.

This report does not include investigations into land contamination associated with asbestos or any other contaminant.

6.2 – Specific caveats

It was agreed with the client that access above or behind known ACM’s was not required within the survey.

It was agreed with the client that core boring into the concrete slabs was not required within the survey.

The client was advised that destructive inspection will involve that removal of a number of windows, which will be required making secure during/after the survey. The client has requested a less intrusive survey into these areas and for the window frames to remain in situ.

Underground services were not included in the survey.

It has been agreed with the client that there was not any unsafe structures on site.

6.0 Exclusions and Caveats:

Page 12 of 36 J023101

7.1 The object of bulk sampling is to identify the nature and extent of any visible ACM.

7.2 Bulk sampling is undertaken inline with the recognised safe procedures in order to cause minimal possible nuisance and potential risk to health of the building occupants and visitors. Bulk samples are taken in accordance with documented in house procedures, following guidelines detailed in HSG264 'The Survey Guide' and HSG248 'The Analyst Guide'. The quantity of samples taken will be minimised by using 'strongly presumed'. Materials that are 'strongly presumed ‘to be similar to a material that has already been sampled will be recorded in the comments section of the survey record and referenced against the original sampled material.

7.3 Bulk samples are returned to the appointed bulk analysis laboratory with the appropriate sample / report reference number. Where appropriate; a label will be left on site adjacent to the sample location.

7.4 The label will indicate the sample number and the date taken. This label can be used along with the report for cross reference purposes.

7.5 Bulk sample analysis is carried out in accordance with HSE document HSG 248 ‘The Analysts Guide’ . Samples are examined under a low magnification stereomicroscope and the fibres teased apart. The fibres are then mounted in liquids of known refractive indices and examined under high magnification using polarised light and dispersion staining in accordance with HSG 248 ‘The Analysts Guide’.

7.6 The bulk sample description and analysis results can be found in Appendix 4 of this report – The analysis certificate.

Samples of material(s) [detailed below] have been examined to determine the presence of asbestos fibres, using Polarised Light Microscopy together with dispersion staining based on the HSE’s guidance document HSG248 and Asbestos Laboratory Services’ documented method. If samples have been delivered to the laboratory, the site address and sample location is reported as provided by the client. Reported results apply to samples as received. Asbestos Laboratory Services are not responsible for the accuracy or competence of the sampling by third parties. Under these circumstances, Asbestos Laboratory Services cannot be held responsible for the interpretation of the results shown. Opinions and interpretations are outside the scope of the UKAS accreditation.

All entries under ‘Fibre Type Detected’ that contain (*) indicate that the sample was found to be deviating from policies defined in document TPS63 (UKAS Policy on Deviating Samples). As a result, the test result(s) may be invalid. The Determination of Asbestos Content Report shall not be reproduced except in full, without written approval of the laboratory. V2, or subsequent “V” numbers, after the report number signifies that the original certificate (or previous amended certificate) has been replaced.
