1.0 INTRODUCTION
1.1 PDP Green Consulting Ltd (pdpG) were commissioned by Colin Bridges, on behalf of the Hall
Trustees, to undertake a Structural Appraisal and Condition Survey of Perranarworthal Village
Hall (The Perranwell Centre).
The purpose of the structural appraisal and condition survey was to ascertain the current
condition of the building, determine if it’s structurally sound and how the building will likely fair
in the next 20 years. The Village Hall is a timber frame building of some 50+ years and is in
need of refurbishment. The Trustees wish to know the condition of the building before carrying
out any refurbishment works.
1.2 No specialist M&E, Geo-technical or Asbestos surveys were undertaken during these
inspections as they did not form part of the agreed scope of works.
1.3 A site visit was made by Mark Ward and Luke Rugg of pdpG on Tuesday 7th August 2018 to
undertake an inspection of the building, including some opening up works.
A second site visit was made by Adam Northridge and Luke Rugg on Friday 24th August 2018
where the primary goal was to complete external inspections of the building envelope and
inspect the condition of the roof and high-level windows.
1.4 Access into the building was provided by Colin Bridges on Tuesday 7th August 2018.
1.5 Weather during the first inspection was mild and mainly sunny with partial cloud cover. It is
noted that there had been a prolonged heatwave over the weeks prior to the visit. During the
second visit, it was overcast with a brief shower towards the end of the visit. However, it is
important to note that there was a prolonged period of dry weather before the inspections were
undertaken. This may have resulted in damp areas drying out and not being visible.
1.6 The first visit consisted of completing opening up works in multiple locations, so that parts of
the structural frame could be locally inspected, and signs of damp investigated.
1.7 The second visit consisted of using a MEWP (Mobile Elevating Working Platform) to allow
access for an inspection of the roof and the high-level windows. However, access to the high
level windows and eaves was limited due to the layout of the site, and being unable to ‘boom’
the MEWP near to the power lines, as Western Power were unable to cover them until
November.
1.8 At the time of the first site visit, a member of preschool staff was present during the inspection
of that area. No one else was present at the centre. A moveable scaffolding tower had been
erected by trustees in the main hall, to assist with the inspection of the roof void.

1.9 This report is based on data obtained from a visual structural appraisal, condition survey and
limited opening up work. Accordingly, no guarantee can be given as to the adequacy or
otherwise of any parts of the structure and its related systems which cannot be seen.
1.10 Only issues/defects which are considered to be relevant for the purposes of this report are
mentioned herein. It follows therefore that there may be old cracks, defects, repairs and other
blemishes which may be visible, but not mentioned in the report.
1.11 It is not intended that this document be used as a specification or direct basis for instructing
any maintenance or repairs. Any works instructed as a consequence of the findings of this
report, must be appropriately designed and specified by a competent professional.
1.12 This report is made for the use of the Hall Trustees. Any use of this report by third parties
without the authorisation of pdpG will be entirely at the risk of the user.

2.0 LOCATION AND GENERAL DESCRIPTION 2.1 The Perranarworthal Village Hall is located at national grid reference SW77416 39154. The
location of the Hall is in Perranwell village which is in the Parish of Perranarworthal, which is
situated approximately 6 miles from Truro.
2.2 The Hall itself is located just off School Hill (a main road) next to a large sports and playing
field. Tarmac surfacing forms access off the main road and a car park to the south and west
of the building, with concrete paths and slabs. To the north of the Hall, there is a separate
small one-story building used by the local football club. Further north and to the east of the
Hall there are residential properties with trees in between.
2.3 The building is constructed using ‘Vic Hallam - Derwent System’ which uses prefabricated
timber and plywood frame which is then insulated and cladd. This method of construction was
used post war for its speed to construct and not for its longevity. Historically, failures in frames
of this type are often attributed to effects of water ingress, points of note are commonly found
around windows and at eaves level. This is of course in addition to the usual areas such as
failed roof coverings etc.
The Derwent system is based on a timber post and plywood beam framing construction. This
system was usually braced by tongue-and-groove roof boards and framed external wall panels
that also act as stress panels.
2.4 The building has a main hall with stage area and is rectangular on plan. This is adjoined to its
south and west by a lobby, two multiple purpose rooms, a kitchen, a number of store rooms
and WC’s in a L shape configuration. The main hall is two storeys in height with the outer
rooms being single storey. However, the site slopes down northwards which has allowed for
a basement under the stage at the north end of the main hall. This is currently being used as
a preschool, which is constructed from masonry walls with concrete floor slab and a boxed
beam across the centre of the ceiling.
2.5 The main hall and outer rooms have flat bituminous felt roofs.
2.6 A small extension has been added to the preschool that houses the toilets and a cloak room.
2.7 The main entrance to the building is on the west elevation with a rear fire exit on the east
elevation. There are additional fire exits from the kitchen and preschool.
2.8 There is a small blockwork boiler room adjacent to the fire escape on the east elevation. There
is a metal storage container outside the boiler room.
2.9 The timber frame is clad in asbestos and slate tiles with painted pebbledash and render at the
lower levels. pdpG were informed during the inspections that most of the lead dressing
between the two types of cladding had been cut away by vandals.

2.10 The majority of the original windows and all external doors have been replaced with PVCu
double glazing, but the original fenestration timber casing remains. It appears some original
single glazed windows remain at high level to the north, south and west elevations of the main
hall.
2.11 Internal finishes are typically painted plasterboard walls with varying door types and floor
coverings. Asbestos floor tiles were noted in two of the rooms. The ceilings have a mixture of
finishes, some rooms have a suspended ceiling fitted below the original. The ceiling in the
main hall is a painted timber fibre board.
2.12 We were told on site that the floor in the main hall had recently been opened up and it was
revealed to be a “semi” sprung floor. The floor is in poor condition and consideration should
be given to its replacement.

3.0 COMMENTARY & OBSERVATIONS
3.1 Opening up Works
Due to the limited amount of opening up works carried out we cannot definitively comment on
the overall condition of the structure and the intention of this report is to comment on the
condition where opened up and inspected. The opening up works have been targeted to areas
known to most likely exhibit issues. The amount of opening up works was limited in order to
limit disruption to the use of the hall. It is important to emphasise that, in order to gain a
complete understanding of the current condition of the building, the entire structure would
have had to be revealed. This would involve removing ceilings, including inside the main hall,
taking down significant amounts of plasterboard and removing asbestos tiles to the exterior of
the building. This would have been prohibitively expensive.
After consulting and reviewing the hall’s asbestos register, opening up works were not carried
out in areas where asbestos was noted or reported to be present. In addition, some ceilings
were not opened up over fears of asbestos in the void above. However, the overall condition
of the roof finishes led us to believe that there was little reason to open these areas.
Some of the opening up locations were undertaken in damp areas, including to the boarding
covering the high level single glazed windows. In the main hall holes were made next to the
entrance to investigate the marks on the wall at ground level. The timber behind the stained
plaster appeared to be dry and in a good condition.
Due to the long period of dry weather before the inspection it is unknown if these areas of
damp worsen following extended periods of wet weather. If the staining returns after being
redecorated or get worse then further investigation in these areas should be undertaken.
3.2 Roof
Generally, the roofs appear generally sound and in a reasonable condition, especially
considering its age. (See Photos 1, 2 & 3). There appear to be signs of several historic patch
repairs that have been applied to the roofs, which appear sound. However, these areas can
be more likely to allow leaks around the edges of the patches. These areas should be
inspected frequently to ensure they remain in good repair (See Photo 4).
The roof surface shows signs of lichen growth and these should be carefully cleared as they
can mask other defects and to preserve the condition of the roof finish.
The leadwork between the lower roof and high-level fenestration needs redressing as it
appears to be beginning to lift up (See Photo 5).

S:\2018 Jobs\J18-053 Perran-ar-Worthal Hall SA\Documents\Report\Village Hall Report 2018.docx Page 9 of 31
The guttering and rainwater goods appeared to be clear and were in a serviceable condition.
Two of the downpipes taking water from the main hall roof on the west elevation originally
would have used horizontal pipes to carry water across the lower outer roof below. At the time
of the inspection only one of the horizontal pipes was installed. We would recommend
reinstalling the other horizontal pipe to allow water to discharge through the rainwater goods
in the manner it was designed to (See Photo 6).
3.3 Timber Frame (‘Vic Hallam - Derwent System’)
We were able to inspect a small part of the roof structure through an access hatch to the south
east corner of the main hall. One of the Derwent plywood beams was visible through this
hatch, also ceiling and roof joists, boarding and polystyrene insulation. The roof space is the
same depth as the Derwent plywood beams, with joists over supporting the roof. Therefore,
we only inspected the one beam.
Non-targeted opening up of the roof is unlikely to have helped with the identification of any
further defects. Instead we took the approach of looking for defects in the bitumen felt roof
and then opening up below them. There were no tears or rips in the felt so no further opening
work was carried out in the ceiling.
From what was visible from the access hatch, the plywood beam, joists and boarding all
appeared in good condition for their age. There was no sign of damp, rot or infestation to the
timbers (see Photos 7, 8 & 9).
The truss ends could not be inspected as abutted and are hidden from view by insulation, ply
boarding, asbestos tiles and gutter externally.
The visible painted timber columns within the main hall appeared satisfactory for their age,
with no obvious signs of deflection and other structural defects.
Where opened up, the walls panels and timber studs appeared in fair to good condition. There
were no signs of damp or any water ingress within the walls.
The condition of the timber wall plate in the main hall and south room were checked. These
seemed in reasonable condition for their age, and at the time, appeared dry.
The suspended ceilings to the west room, WC’s and lobby were lifted. The partitions to the
WC’s and lobby are constructed from modern timber stud partitions and plasterboard. The
lifting of the ceilings did not reveal anything of concern or structurally significant. As an
advisory, where ducting has been installed through the plasterboard above the female WC
ceiling the installation has been done to a poor standard (See Photo 10).
The structure and condition of the preschool area appeared satisfactory.

3.4 External Walls
Generally, the externals walls appeared to be structurally sound.
The pebbledash and render lower wall sections are in relatively good condition. There is the
odd surface crazing, algae staining, and chips, but we consider these cosmetic issues.
Some minor cracking was noted to the render finish. On the east elevation, there appears to
be a very fine surface crack extending down from the window to ground floor (See photo 11).
At the time of the inspection, none of these cracks were considered to be structurally
significant.
Past damp issues within the preschool were reported to pdpG during the first inspection.
Internally, the areas of damp ingress had been redecorated however, some algae and dirt
staining was noted externally on the west end of the north elevation of the preschool (See
Photo 12). The exact cause of the external staining is unknown, but it is possible that this has
resulted from back splash and./or cleaning of boots and mats.
3.5 Asbestos and Slate Cladding
Above the preschool fire exit one of the tiles has slipped. Closer inspection of this found that
the tile was in a stable position at the time of the inspection, however this should be repaired
as soon as possible, as it could become a health and safety concern should it fall allowing
water penetration into the structure (See Photo 13).
It appears that over time, some of the asbestos tiles have been replaced with slate tiles in
select areas. We removed a section of the slate tiles to inspect the construction behind and to
gain an understanding as to how the slates were laid.
It was found there was insufficient slate lap, and bitumen felt has been used to seal the joints
(See Photo 14). These joints are prone to failure and can allow for water to be driven in to the
structure. This does not appear to have happened in the area of opening up, but is a concern
for the future.
Leadwork between the render and the asbestos slate cladding has been cut away by vandals
(See Photo 15). At the time of the inspection, there was no obvious signs of water ingress
resulting from the lack of flashings. However, new lead flashings should be reinstated, or an
appropriate alternative solution used, to ensure the building remains water tight.

3.6 Windows
The PVCu windows appeared in good condition but some timber casings at ground floor are
in need of redecoration, with some others starting to degrade (See Photo 16). If these fail,
they can allow water to reach the structure of the building and, therefore, should be
redecorated and/or repaired. However, careful consideration must be given as asbestos tiles
will need to be removed if the timber casings are to be removed and replaced.
The original single glazed high-level windows to the main hall elevations are in a poor condition
and in need of replacement. The frames show signs of degradation. Under closer inspection,
frames to the south and west elevations appear to be warping both vertically and horizontally
(See Photos 17 & 18). This is likely to allow moisture to enter the building. It is possible that
they could fail and allow water ingress into the frame of the building. On the south elevation
one of the panes of glass was cracked (see Photo 19).
High-level windows to the north and east elevation were not able to be fully inspected because
of their location. From ground level, windows above the preschool (east elevation) have a
green hue to them which could indicate algae growing behind the glass (See Photo 20). This
suggests the windows and/or framing is not water tight. Internally, the majority of high-level
windows are boarded over, but damp staining was visible from within the main hall to these
boards. All single glazed high-level windows and frames should be replaced with new double
glazing to arrest damp ingress in these areas. Another option would be to remove the windows
and replace with solid insulated panels.
3.7 Doors
The majority of external doors, including the main entrance doors, preschool doors and fire
exits appeared serviceable.
The boiler room door is in need of redecoration but was in working order (See Photo 21).
Internally the only door that was noted to be in a poor condition was that of the seating store
(See Photo 22). The remaining doors are in a fair to good condition.
The internal fire doors within the Hall were not inspected for compliance or presence of
intumescence strips and smoke seals. It is advisable that all doors to the entrance Foyer, and
those adjacent the east (rear) fire exit, are fire rated and are fully compliant with regulations.
However, all major rooms appear to have alternate exit routes. This should be included within
the buildings Fire Risk Assessment.

S:\2018 Jobs\J18-053 Perran-ar-Worthal Hall SA\Documents\Report\Village Hall Report 2018.docx Page 12 of 31
3.8 Floors
It was noted that there are some damaged asbestos floor tiles within the west room and Table
Store (See Photo 23). At present, this is not considered a major hazard to users of the rooms,
but the asbestos tiles should be completely removed, in accordance with the current Control
of Asbestos Regulations 2012. It would be prudent in the meantime to cover or seal around
the damaged tiles.
The remaining floor surfaces are in fair to good condition. The store room floors are scratched
but otherwise appear be to serviceable. Some of the vinyl floors within WCs need resealing
between the floor and wall junction, as gaps are starting to develop.
3.9 Interior Decoration
Generally, the interior finishes are fair to good. The entrance lobby, kitchen preschool and
WC’s appear to be of more recent décor. In the store rooms there are scuffs and marks with
general wear and tear to the main hall floor.
3.10 Surroundings
The tarmac, slabs and concrete surfacing around the building currently appears adequate and
fit for purpose. Some light maintenance and weeding are required to the hardstanding’s, we
recommend that the Trustee’s allow for this work as ongoing maintenance.
The storage container is situated on concrete hardstanding which extends out as the ground
level drops away. In some areas the sides of the hardstanding have spalled and fallen away
resulting in small voids and exposure of a rubble fill. This should be repaired before the
concrete deteriorates further. (See Photo 24 & 25).
Some gulley’s below downpipes were observed to be blocked by debris and vegetation. These
should be cleared and checked regularly as part of the Halls ongoing maintenance.
3.11 Other Comments
It is unknown if the Hall has an Energy Performance Certificate (EPC), the need for an EPC
and compliance should be established and works for compliance included in the future
maintenance and refurbishment strategy of the Hall.
It should be noted that if additional insulation was added or if the building was to be re-clad,
then the building would have to perform to modern standards, and possibly require a EPC.
This would require significantly more insulation than is currently installed and would result in
more dead load supported on the structural frame. The frame would therefore require a full
structural analysis to determine if it had sufficient capacity to support these additional loads.

If the bituminous felt roof was to be replaced, similarly, the replacement would have to meet
current building regulation requirements and require additional insulation. This would impose
more load onto the existing structure and would therefore require a full structural analysis
determine if it had sufficient capacity to support these additional loads.

4.0 CONCLUSIONS & RECOMMENDATIONS
4.1 It is our opinion that, at the time of the inspection, the general structural condition of
Perranarworthal Village Hall appeared fair to good, there was no evidence of significant
structural defects or any causes for immediate concern.
4.2 There was no sign of rot in any of the observed timbers, but as our opening up works were
limited to areas where surface damp issues were present these defects cannot be ruled out
in areas that were not opened up.
4.3 The structural timber frame, as long as it stays dry and moisture content remains should
remain serviceable in the short to medium term provided it is not subjected to significant
additional loading.
4.4 While the building has provided for the community for the last several decades, it should be
remembered that it was built using a method of construction that was used for its speed of
assembly, not its long-term durability. Any significant alterations to the structure particularly
those that involve removal of external walls that are potentially utilised for providing lateral
stability to the structure would need to be considered by a structural engineer. In structures
of this nature it is not always clear how the structural system functions, changes such as the
introduction of additional insulation, significant changes to the cladding and/or roof finish will
require both the input of a structural engineer and building regulation approval.
Due to the use of a stressed skin system, more significant alterations of remodelling of the
structure (particularly the removal of walls) will require the structural analysis, which could
determine the need for further strengthening of the existing frame. Therefore, depending on
the scope of alterations reuse of the structure may not be cost effective once the cost of
additional strengthening works is factored in. The services of a structural engineer should be
sought at early stages of any scheme to comment on the implications of any alterations to
prevent unexpected costs later in the project.
4.5 The roof is generally in a good condition for its age, but it is towards the end if its serviceable
life and will likely require replacing in the near future. The life of the roof could be extended by
a further 10 years by adding a single ply membrane system to the current roof. However, a
specialist roofing contractor would need to provide a survey to confirm its suitability for a
system of this type.
4.6 The vanished lead flashings must be replaced as they do not offer adequate protection from
the driving rain. Water, via capillary action, could track into the building and ultimately affect
the structure if the flashings are not replaced.

4.7 If the Trustees deem it viable and wish to carry out refurbishment works to the Hall, it is
recommended as part of these works the remaining single glazed windows at high-level
should be replaced with modern double glazing. If the windows fail they can allow water to
enter the structure and cause damage, potentially weakening the structural frames.
4.8 A maintenance budget should be allocated for the replacement of any damaged or degraded
asbestos tiles. It would be prudent to consider the replacement of all the asbestos tile cladding
within the next 10 years, as if any break they could potentially release asbestos fibres into the
air.
We advise that following any leaks from the roof or windows that the frames be inspected to
ensure the timber has not become saturated or degraded in anyway. Any damp staining
should also be investigated, which could require further opening up works.
The Trustees may want to consider ongoing maintenance programmes (if not already in place)
of the Hall grounds, especially to the concrete paths and around the rear of the building, east
elevation, adjacent the metal container.
