PENNINE Ecological 1
PART 1: INTRODUCTION:
1.1 REASONS FOR SURVEY:
PENNINE Ecological have been commissioned by Lancashire County Council (Estates) to
undertake an Extended Phase 1 Survey and Evaluation of land at Barnes Road, Skelmersdale,
Lancashire PR7 5HS.
The study is required in association with the demolition of the existing scout hut on the site and
the development of the former school playing fields.
The study includes the following elements:
• Extended Phase 1 Habitat Survey.
• Preliminary Bat Roost Survey.
• Evaluation of the breeding bird potential.
• Badger Survey.
The study also includes a full evaluation of the ecological significance of the survey and
recommendations/precautions where appropriate.
The surveys were undertaken by Ian Ryding a surveyor with 29 years experience in a wide range
of ecological survey and assessment.
1.2 SITE LOCATION:
The site is located on the former school playing field to the rear of Park Children's Centre, East
of Barnes Road, Skelmersdale. The site also includes the Scout Hut within the grounds of the
children's centre. The location of the study area is shown on Map 1 in the Appendix.
1.3 SURVEY METHODOLOGY:
The methodologies where specific surveys were applied are outlined below.
1.3.1 Extended Phase 1 Habitat Survey:
An Extended Phase 1 Habitat Survey (Nature Conservancy Council 1990) of the survey area was
undertaken on 2nd
March 2017. The site’s habitats were fully mapped and higher vascular plant
species (where present) were recorded and given abundance values according to the standard
DAFOR scale where:
D = Dominant
A = Abundant
F = Frequent
O = Occasional
R = Rare
Where appropriate the above DAFOR values can be prefixed by the letter L (locally) or V
(very), to provide more subtle biogeographical data.

1.3.2 Preliminary Bat Roost Survey:
The preliminary roost survey was undertaken on the 2nd
March 2017 following the methodology
outlined in Bat Surveys for Professional Ecologists: Good Practice Guidelines (3rd edn) Collins,
J. Bat Conservation Trust (2016)
The survey was undertaken by an experienced preliminary assessor for bats in consultation with
a Level 2 licensed bat ecologist.
The survey included standard non-intrusive searches for potential roosts in the building affected
by the proposals.
The inspection included the following:
• Searches for feeding remains, staining and bat droppings on floors around the edge of the
walls.
• Searches for suitable entry and exit points in gaps between masonry, around eaves,
soffits, flashing and/or under tiles etc.
• Holes and fissures in trees that might be suitable for roosting bats.
The survey was undertaken from ground-level using close-focusing Leica Trinovid 8x42
binoculars.
1.3.3 Other Species:
During the survey, an evaluation of the site's nesting bird potential was undertaken. In addition,
the site was surveyed for signs of badger use/habitation.
1.3.4 Surveyor Experience:
The surveyor and author of this report, Ian Ryding, has 29 years experience in ecological survey
and evaluation. Key skills include the following.
• Extended Phase 1 Habitat Survey and National Vegetation Classification Survey.
• Highly proficient field botanist, including some difficult plant groups.
• Breeding and wintering bird survey.
• Mammal surveys including surveys for badger, water vole*, otter*, brown hare and
preliminary bat survey.
*Over 250km of river reaches surveyed in England.
• Extensive experience in great crested newt (GCN) survey, evaluation, licensing and
mitigation. Natural England Class Licence WML-CL08 held.
Extended Phase 1 Survey & Evaluation
Land at Barnes Road, Skelmersdale, Lancashire.
PENNINE Ecological 3
• Ecological Evaluation and Impact Assessments in association with large scale
commercial development and civil engineering.
1.4 SURVEY CONSTRAINTS:
The vegetation survey was undertaken at a sub-optimal time of year, however the communities
present were well defined and there was enough vegetative material available to enable a good
assessment of the habitats to be made. The constraint in respect of vegetation is therefore
considered to be minor.
There were no significant constraints to any other aspect of the survey.

PART 2 SURVEY RESULTS:
2.1 DESK BASED STUDY:
A request was made to Lancashire Environmental Record Network (LeRN) to obtain details of
any biological records relating to the site.
DEFRA’s ‘Magic’ website was also referred to as part of this study.
The results of the desk study revealed the following information.
• The site has no statutory or non-statutory wildlife or ecological designations.
• There are no statutory wildlife sites, Sites of Special Scientific Interest (SSSI) etc within
2km of the site.
• There are no Biological Heritage Sites within 1km of the site.
• There are seven Biological Heritage Site between 1-2km of the site, all are separated
from the site by continuous built-up environment.
• There are no on-site ponds and the nearest off-site pond is approximately 800m north of
the site.
• None of the records supplied by LeRN relate to the site and there are no LeRN records
within 500m of the site.
The ecological data plan supplied by LeRN is provided in the appendix. Apart from the key
protected species locations shown on the LeRN plan, the full list of species records is not
reproduced as none are associated with the site and are considered to be beyond the sphere of
influence of the proposal.
2.2 EXTENDED PHASE 1 HABITAT SURVEY:
2.2.1 General Description:
The site is largely composed of a former school playing field that is entirely enclosed by
residential development. The grasslands were formerly composed of short amenity swards,
however as the playing fields are now out of use a simple maintenance regime of several cuts per
year is applied to maintain the grasslands 'in good heart'.
As the amenity mowing regime is no longer applied, the grasslands are classified as semi-
improved, and 'poor' on account of their low species diversity.
The grassland has a small stand of semi-mature trees in the north east corner, and there is a
scout hut of mid-20th century origin situated adjacent to Barnes Road.
2.2.2 Extended Phase 1 Habitat Survey Target Notes:
Survey locations, Target Notes and the proposed working area locations are shown on Map 1 in
the Appendix. Note: All species nomenclature follows Stace, C. (1996) ‘New Flora of the British
Isles’ - definitive English names.
Extended Phase 1 Survey & Evaluation
Land at Barnes Road, Skelmersdale, Lancashire.
PENNINE Ecological 5
Target Note 1:
A former school sports field that is classified as semi-improved poor grassland on account of the
relaxed mowing regime and low species diversity.
The grassland is dominated by a mixture of common grasses and there is low herb content. The
presence of sheep's sorrel indicates the presence of localised acidic overtones, however these
areas are too small to represent on the habitat map.
There is a small seasonally-wet hollow in the centre of the site, the flora in this area is composed
of the same grasses as the surrounding field, which confirms the very ephemeral nature of the
open water.
Several stands of bramble and regenerating cherry saplings and planted small sycamore occur
around the periphery of the site. A semi-mature Norway maple is also present here.
On parts of the boundary drainage is impeded and common reed is spreading from neighbouring
properties.
The grassland has a broad affinity with the MG7 Lolium perenne leys and related grasslands, in
particular the Lolium perenne - Poa trivialis sub-community as defined in British Plant
Communities.*

Target Note 2:
This is a distinctly different sward to that described in Target Note 1 as it is a re-sown area in the
south-west corner of the site. This was the site of a former scout hut that was demolished and the
land remediated and sown with a simple amenity grass mixture.
The grassland is classified as improved and is dominated by red fescue with occasional
Yorkshire-fog, the only species recorded in this area.
Several raspberry canes and bramble vines are established on the boundary of this area.

PENNINE Ecological 6
This area is immature and highly artificial and has no obvious affinity with any grassland
communities as defined in British Plant Communities.*
*(Rodwell et al 1992)
Target Note 3:
A small formalised area of what was probably once a garden on the western boundary of the site.
Three mature sycamore, a single ornamental cherry and stands of introduced shrub surround an
area of improved grassland that is likely to be a former lawn area.
The grassland here is species-poor and composed of a mixture of red fescue and common bent.
A strip of ivy-dominated land forms a narrow strip immediately north of this area, which
suggests that the area also once had some tree/shrub cover in the past.
This area is highly artificial and has no obvious affinity with any communities as defined in
British Plant Communities.*

2.3 PRELIMINARY BAT ROOST SURVEY:
2.3.1 General Description:
This element of the survey is was applied to the scout hut and several trees located on the
periphery of the site.
The scout hut is of concrete block construction with a pitched bitumen felt 'tile-effect' roof. The
building is in good condition externally and internally and is weatherproof. A low, flat-roofed
tower housing a water header tank is elevated slightly above ridge height and there are two metal
roof vents on the ridge.
The trees include a single semi-mature Norway maple in the south-east corner of the site and a
group of three early- mature sycamore and a single cherry var. on the western boundary.
For survey purposes these trees are referred to as Tree Group (TG) 1 and 2 respectively and are
shown on Map 1 in the appendix.
It should be noted that all other trees on the site are immature and obviously unsuitable for
roosting bats.
Photographs 7 - 16 show the prevailing conditions in the building and the trees.
2.3.2 Survey Results:
Scout Hut:
The following features were noted.
• The pointing is in good condition with no gaps.
• The fascia boards are tight fitting overall with no significant gaps.
• The roof is of non-standard construction and composed of strips of 'tile-effect' bitumen
felt nailed to battens that are fixed to sarking boards.
• The felt is fixed in a way that excludes access by bats.
• The roof verge has a matching bitumen felt capping. Small gaps are present very locally.
• There is a matching bitumen felt ridge and there are gaps below the tile profiles and the
ridge. The type of roof construction often apply profile fillers to fill such gaps, however
examination of the general construction arrangement suggests that wooden battens might
have been used. A binocular inspection indicates that one of these features are likely to
have been installed. (See Figure 1 in Site Photographs - Bats below)
• There are two large steel vents on the ridge. Vents such as these normally have insect
screens to prevent access.

Land at Barnes Road, Skelmersdale, Lancashire.
PENNINE Ecological 11
• The header tank tower is flat roofed with tight-fitting fascias. The tower is accessed from
the roof and the door is tight-fitting also.
• The interior of the building has a small low roof void at one end, whilst the main body of
the building has a boarded ceiling of UPVC. There are localised gaps between the ceiling
boards and the wall.
• No evidence of bat habitation was found i.e. bat droppings on or along the base of
interior walls below the ceiling gaps, or urine staining.
•
• No evidence of bat habitation (droppings etc) was found along the base exterior walls or
on window sills.
• No feeding remains were recorded.
Based on the points above, roost potential is very limited and restricted to several small gaps
below the verge capping.
The gaps below the ridge appear to have either profile fillers, or are blocked by battens leaving
only shallow exposed holes.
Based on the features recorded during the survey, the building is considered to have less than
low value for roosting bats.
Tree Group 1(TG1):
This is a single semi-mature Norway maple located in the south-east corner of the playing field.
The tree has been subject to heavy vandalism including extensive bark stripping.
The tree has no holes of fissures and is therefore unsuitable for roosting bats.
Tree Group 2 (TG2):
Three early mature sycamore trees and a single ornamental cherry variety.
The cherry has very narrow girth and lacks any feature suitable for roosting bats.
The sycamore appear even-aged and have a diameter of approximately 0.4m or less, one is also
multi-stemmed.
Vandalism damage is evident on some of the trees but there are no holes or fissures suitable for
roosting bats. Therefore bat roosts are absent in this tree group.

on the following page.

Foraging Areas:
The land overall has limited foraging potential as it is largely open and exposed and lacks
foraging lines such as hedgerows and woodland-edge etc.
Consequently foraging will be largely restricted to the stand of trees and scrub on the periphery
of the site along the boundaries of the neighbouring gardens.
The surrounding land is urban and composed of a wide range of housing that includes 19th and
early- mid and late 20th century housing, which is likely to provide extensive roost opportunities
based upon the general construction of these house types as observed during the survey.
Despite the presence of potentially suitable roost opportunities in the houses locally, the main
focus of foraging bats locally will be the Tawd Valley, Dalton Park and the extensive farmland
to the south, west and north of the site.
The site itself is considered to have only minor foraging potential for bats.
2.4 GREAT CRESTED NEWT EVALUATION:
2.4.1 Evaluation of Features:
There are no ponds on site and the site itself is isolated within extensive residential development.
The nearest off-site pond is over 800m from the site.
Extended Phase 1 Survey & Evaluation
Land at Barnes Road, Skelmersdale, Lancashire.
PENNINE Ecological 18
The small seasonally-wet hollow is present in the centre of the field. The anomaly in the
topography here is as a result of the presence of a former farmstead Birche's Farm, rather than a
relict pond.
The waterbody is approximately 120m² and has a depth <0.2m.
The flora present reflects that of the surrounding field rather than a pond flora, thus indicating
that the feature is highly ephemeral to the extent that the seasonal presence of water has little
influence on the grassland.
Waterbodies of this type are incapable of supporting GCN or any other amphibian species as the
larvae wouldn't have time to develop before the area desiccated.
Therefore no impacts on GCN or its terrestrial habitat are predicted.
2.5 EVALUATION OF OTHER FEATURES:
2.5.1 Breeding Birds:
Breeding bird potential is limited to the trees, some of the scattered scrub and the stands of
introduced shrub on the periphery of the site.
Given the generally sparse nature of the vegetation present and its close proximity to housing
with the inevitable population of domestic cats, disturbance levels to nesting birds is considered
to be moderate to high.
Consequently these areas are incapable of supporting more than very low numbers of common
birds of 'local' (i.e. Parish) value only.
The grassland is considered to have 'negligible' value to ground-nesting birds on account of its
'urban isolation', relatively small size, feline predation and maintenance mowing regime which
takes place several times a year.
2.6.2 Badger:
The whole site was walked and examined for signs of badger activity, including setts, latrines,
paths, runs, foraging areas and scratching posts. No evidence of badger activity/occupation was
found during the survey and the site is totally unsuitable for badger habitation. Based on the lack
of badger signs, the species is considered to be absent on the site and locally.

PENNINE Ecological 19
PART 3 SUMMARY EVAULATION & RECOMMENDATIONS:
3.1 SUMMARY EVALUATION OF FINDINGS:
The desk study, field survey and evaluation of the site revealed the following information.
• The site is urban and isolated from any other area of green space or wildlife corridor by
continuous built up environment that includes roads, residential and industrial
development.
• The site has no statutory or non-statutory wildlife or ecological designations.
• There are no statutory wildlife sites, Sites of Special Scientific Interest (SSSI) etc within
2km of the site.
• There are no Biological Heritage Sites within 1km of the site.
• There are seven Biological Heritage Site between 1-2km of the site, all are separated
from the site by continuous built-up environment.
• There are no on-site ponds and the nearest off-site pond is approximately 800m north of
the site.
• None of the records supplied by LeRN relate to the site and there are no LeRN records
within 500m of the site.
The evaluation of the survey findings are summarised further below.
3.1.1 Vegetation/Habitats:
The proposal will directly affect very common habitats with low levels of 'naturalness' and
biodiversity. These include former amenity grassland and occasional non-native trees,
ornamental shrubs and scrub.
The habitats affected are considered to have low ecological value and are of 'site' interest only.
3.1.2 Bats:
Scout Hut:
The survey found no sign of bat habitation in the form of bat droppings on or along the base of
interior/exterior walls, floors or on window sills.
There is bitumen felt cladding on the two gable elevations and there is no means of bat ingress*
except for occasional small gaps behind the verge capping.
*See Figure 1.
The roof is of non-standard construction and has the same tile-effect felt sheets fitted. There is a
matching ridge where gaps are present behind which is thought to be a profile filler or wooden
battens. The fascia boards where present are tight fitting with no gaps.
Based on the very limited features recorded during the survey, the building is considered to have
'less than low potential' for roosting bats.
Extended Phase 1 Survey & Evaluation
Land at Barnes Road, Skelmersdale, Lancashire.
PENNINE Ecological 20
Trees:
The survey found no holes/fissures in any of the trees with the potential to support roosting bats.
3.1.3 Great Crested Newt:
The site is isolated from all ponds by extensive residential areas and roads. The waterbody
present on site during the survey is ephemeral and considered incapable of supporting viable
populations of amphibians.
Based on the above, the possibility of GCN being present is considered to be remote.
3.1.4 Birds:
Breeding bird potential is limited to the trees, scrub and the stands of introduced shrub on the
periphery of the site.
These areas are incapable of supporting more than very low numbers of common birds of 'local'
(i.e. Parish) value only.
The grassland is considered to have 'negligible' value to ground-nesting birds on account of the
prevailing conditions including its urban location, small size, domestic cat presence and
maintenance mowing regime which takes place several times a year.
3.1.5 Badger:
The site is unsuitable for badger habitation and no evidence of badger activity was found during
the survey, therefore the species is considered to be absent on site and locally.
3.2 RECOMMENDATIONS:
The following section outlines any mitigation or precautions required in respect of the survey
findings.
3.2.1 Vegetation/Habitats:
No further surveys recommended.
3.2.2 Great Crested Newt:
No impacts on GCN or its habitat are predicted and no further surveys or precautions are
recommended.
3.2.3 Bats:
The preliminary roost survey has indicated that the level of roost potential is not considered to
exceed 'less than low' potential.
Extended Phase 1 Survey & Evaluation
Land at Barnes Road, Skelmersdale, Lancashire.
PENNINE Ecological 21
In this instance due to the very low risk of bats being adversely affected by the proposals for the
building, emergence surveys are not recommended. Instead, precautionary measures should be
applied prior to any development and should include the following.
• Licensed (Level 2) bat ecologist presence whilst the roof/ridge tiles and external cladding
is being removed.
In the unlikely event of bats or evidence of bats being found during the inspection, work must
stop and the ecologist will provide guidance on how to proceed with the development. Actions
might include a licence application to Natural England.
3.2.4 Breeding Birds:
Breeding bird potential is limited to the trees, scrub and the stands of introduced shrub on the
periphery of the site, therefore no further surveys are recommended.
However, to avoid impacts on nesting birds, if any of the trees/shrubs need to be removed, then
this must be done outside of the bird breeding season during September-February. Removal in
the period March-August must not be undertaken unless an ecologist has inspected the site and
deemed the trees/shrubs to be clear of nesting birds.
Trees and shrubs should form part of the landscaping scheme to replace the nesting habitat lost
to development.
3.2.5 Badger:
Badger are absent on site and locally and no further surveys or precautions recommended.

1. EXECUTIVE SUMMARY
On the instruction of Gary Jones (LCC Estates) a representative of Lancashire County Scientific Services has attended the Scouts Hut, Barnes Road, Skelmersdale, WN8 8HN to carry out an Asbestos Management Survey. The survey only covered the areas marked on the site plans (Appendix 1d) as directed by Gary Jones. The remaining areas in the building were outside the scope of the survey. The purpose of the survey was, as far as reasonably practicable, to identify the presence of any asbestos containing materials. The following tables provide a summary of the locations of the asbestos containing materials identified and any locations that were not accessed during the survey.

1.2 AREAS NOT ACCESSED
Whilst every effort has been made to identify and examine all suspect materials within the areas of the premises visited, we cannot guarantee that all asbestos containing materials have been located. Some materials may well be hidden within the fabric of the building and may only become evident when any demolition work or major refurbishment is being carried out within or on the premises. See also the general exclusions in Appendix 4. Refer to the site plans in Appendix 1(d). Any areas not highlighted are outside the scope of this survey.
Until the areas listed below have been surveyed and tested by competent persons, they must be presumed as containing asbestos materi als and no access is permitted until a further inspection has been undertaken by L ancashire County Scientific Services.

3. METHODOLOGY
Management Survey
The purpose of this type of survey is to locate as far as reasonably practicable, the presence
and extent of any asbestos containing material. Representative samples are collected and analysed to confirm the presence or absence of asbestos containing materials. If the material sampled is found to contain asbestos, other similar homogeneous materials used in the same way in the building can be strongly presumed to contain asbestos.
The sampling strategy is designed to cause minimal damage to the fabric of the building. As such, it should be noted that materials behind wall panels, fixed ceilings/boarding etc may contain asbestos. This should be borne in mind when undertaking major structural work. In the event of major structural work or demolition, a Refurbishment and Demolition Survey should be carried out.
Sampling is not undertaken where damage may affect the efficiency of the plant, e.g. flue
pipes and gaskets. Sampling is also not carried out where there is a physical danger present such as electricity
fuse boxes/distribution boards etc, boilers, machines in operation etc.
Bulk sampling strategies and procedures have been performed in accordance with HSG 264 – Asbestos: The Survey Guide.
Material Assessment Scores
Materials with assessment scores of 10 or more are regarded as having a high potential to
release fibres, if disturbed. Scores of between 7 and 9 are regarded as having a medium potential, and between 5 and 6 a low potential. Scores of 4 or less have a very low potential to release fibres. Non-asbestos materials are not scored.
SV163/17WP Page 6 of 25
Priority Assessment Scores The priority assessment looks at the likelihood of someone disturbing the ACMs. Four parameters determine the likelihood of this occurring:

The parameters are scored on a scale of 0 to 3, which when added together give the overall priority rating. It is the responsibility of the duty holder to ensure that a priority assessment has been undertaken for all asbestos containing materials identified within the survey report. The priority assessment contained within this report is for technical guidance only and is based on the conditions at the time of the survey and should be reassessed if conditions change e.g. usage, occupancy etc. Total Risk Score In some cases there may be ACMs in many different locations throughout your premises. Budget and time constraints may not allow you to deal with all of them straight away, if this is the case you will have to prioritise them, dealing with those that pose the highest risk to health first. You can do this by dealing with the ACMs that have been given the highest Total Risk Assessment Score first. The Total Risk Assessment Score is the sum of the Material Risk Assessment Score and the Priority Assessment Score: Total risk = Material assessment score + Priority a ssessment score Risk Score Assessment
20 or More High Risk 14 to 19 Medium Risk 9 to 13 Low Risk 8 and below Very Low Risk

4. CONCLUSIONS
The Management Survey at The Scouts Hut, Barnes Roa d, Skelmersdale, WN8 8EH identified the following asbestos containing materi als (ACM’s)
• Asbestos cement sheets to the ceiling in area 56. I t is strongly presumed that the asbestos cement is present above the false ceiling in areas 51, 52, 53, 54, 55, 56, 57, 58, and 59. The total area was approximately 135m 2.
• Asbestos cement panels to gable end walls to areas 52, 56, 57, and 59. The total area was approximately 30m 2 per gable end wall.
• Asbestos reinforced resin panel to the electric met ers in area 58. The total area was <1m2.
• Asbestos containing materials presumed to be presen t within the electrical distribution boards in area 58.
5. RECOMMENDATIONS
• The asbestos cement sheets to the ceilings in areas 51, 52, 53, 54, 55, 56, 57, 58, and 59 must be safely managed in-situ and their conditi on monitored on an annual basis.
• The asbestos cement panels to the gable ends in are as 52, 56, 57, and 59 must be safely managed in-situ and their condition monitore d on an annual basis.
• The asbestos reinforced resin panel to the electric meter in area 58 must be safely managed in-situ and its condition monitored on an a nnual basis.
• The electrical distribution boards in area 58 must be safely managed in-situ and their condition monitored on an annual basis.
• Lancashire County Scientific Services should be con tacted if it becomes necessary to
work outside the areas specified in this report. If necessary, please contact Lancashire County Scientific Services for advice .
Where identified asbestos containing materials (ACMs) are to be retained, it is important to implement a management programme, which should include:
� Producing of a register of the locations of all the ACMs being retained on the
premises.
� A maintenance system being set up requiring that anyone carrying out work in the building should consult the register to ensure that any activity being carried out will not disturb the ACMs.
� The register is updated as and when any ACMs are removed or repaired etc. � That the ACMs are inspected visually on a regular basis and a record of the inspection
is made. � Any retained ACMs within the premises should be encapsulated if not already sealed
and preferably labelled with asbestos warning labels or tape.
� Carry out a Refurbishment or Demolition Survey before any major refurbishment or demolition work takes place.

APPENDIX 4 – GENERAL EXCLUSIONS
Health and Safety is an important consideration during our surveys and if the team find an area where access or sampling will present an unacceptable risk the survey will be suspended until suitable controls have been implemented. Such situations will include: accessing confined spaces, work at heights, work near active equipment etc.
Areas above office equipment, process equipment, etc. will not be accessed where there is a risk to the surveyors and will be subject to a visual assessment only.
Surveying of live plant, heaters or process equipment shall be restricted to accessible external areas only. Lancashire County Scientific Services survey teams are not trained to dismantle and reassemble these items and will not compromise any fixed guards, etc.
Moving plant and equipment shall be excluded from the survey unless an inspection is requested by the client. Access will only be gained once the plant has been isolated by the client.
Lift shafts will only be accessed by the survey team when accompanied by a competent lift engineer. In the absence of a lift engineer, the lift shaft shall be presumed to contain asbestos.
Flooded basements or other areas where surfaces are covered by water or other liquids shall be recorded as inaccessible areas. Lancashire County Scientific Services cannot be held responsible for the presence of asbestos in flooded areas.
Lancashire County Scientific Services shall only access high-level roofs from safe working platforms or edge protected flat roof areas. Lancashire County Scientific Services cannot therefore accept responsibility for asbestos products located on non-accessible high roofs areas.
Lancashire County Scientific Services shall not normally access loft spaces that are not immediately visible or accessible from safe walkways. Periodic inspection will be made beneath loft insulation.
HSG 264 – The Survey guide allows surveyors to presume or strongly presume that visually similar materials are likely to contain or not contain asbestos. In these instances there is the possibility that visually similar rogue items of asbestos containing material may not be identified.
During the survey, the survey team will use their judgement to determine whether it is possible to sample materials without causing damage to the structural integrity of the building. Examples of this may be that sampling of the roofing felt may result in a leak in the roof, or breaking an external under-window panel may result in weather penetration. In such instances either no sample will be taken, and a presumption made, or a much smaller than normal sample will be taken. For small samples the accuracy of the analysis will be reduced.
Textured/decorative coatings are non-homogeneous materials and do not have an even distribution of asbestos throughout the material and asbestos may only be present at trace levels. Lancashire County Scientific Services will endeavour to take representative samples of these materials but cannot accept responsibility for localised inconsistencies in their composition.
In buildings where there are large amounts of stored items, Lancashire County Scientific Services cannot accept responsibility for any asbestos containing materials which have been concealed by these items.
The survey shall not include any items contained within the ground beneath or adjacent to the surveyed areas, or items stored inside containers, drawers, cupboards, etc. within the building/site.
SV163/17WP Page 23 of 25
Lancashire County Scientific Services cannot accept responsibility for the identification of any sealed void within structures such as bricked up basement rooms, service risers, etc. or where there is no evidence to support its presence such as clearly marked drawings. Accurate site plans are extremely important in this regard.
Where an area has been previously stripped of asbestos and new coverings added it must be pointed out that asbestos removal techniques have improved steadily over the years. Previous asbestos removal works may not be up to the standards currently in force and therefore debris may be present below new coverings. Asbestos may well be hidden as part of the structure to a building and not visible until the structure is dismantled at a later date. Accordingly, no samples have been taken from restricted areas and asbestos should be presumed to be present. Any material that is found to be suspicious and not detailed as part of the survey report should be treated with caution and asbestos should be presumed to be present until analysis proves otherwise.
