1. BACKGROUND.
The Sark slaughterhouse provides the sole facility on Sark for the slaughter, cold
storage and butchering of farm animals, principally cattle, sheep, goats and pigs. It has
been in its present form for 25 years with sundry minor modifications over time,
mostly at the lowest cost. The slaughterhouse is the sole means to provide local meat
to Sark. Sark farm animal products also find a very significant outlet by being exported
to Guernsey as meat.
Guidance on the standards required to operate the Sark slaughterhouse is obtained
from Guernsey via the Guernsey States Veterinary Service. Given the key part that the
Guernsey market plays in the economics, achieving standards that are acceptable to
Guernsey is critical. The core requirements that the Guernsey Veterinary Service
require Sark to meet is enshrined in EU standard EC 852/2004 – The Hygiene of
Foodstuffs and in particular Annex 2 (General Hygiene Requirements For All Food
Business Operators). The UK Meat Industry Guide is the practical embodiment of good
practice of the EU regulation.
Following a recent review. the Government of Sark wishes to continue to provide
slaughtering and butchery facilities on Sark by refurbishing and upgrading the existing
slaughterhouse in order to provide a modern and robust facility that will meet the
known and appropriate standards for the future. The Government wishes to obtain
tenders during the summer of 2017 for the works and materials needed for the
refurbishment with the view of implementing the upgrade in January/February 2018.
The work will be implemented using a series of work packages which will be
coordinated by a person to be appointed by the Government. The work packages will
be divided as follows:
• Package 1: Building works, including all strip out, refurbishment of the existing
building, building modifications and installation of free issue fitments and
fittings. This package will also include the electrical and plumbing works.
• Package 2: Supply of the refrigeration panels to line the hygienic parts of the
building and form the new cold stores.
• Package 3: Supply of the specialist internal doors for the cold stores and
“white” areas.
• Package 4: Supply of stainless steel wall protection panels.
• Package 5: Specialist installation of the refrigeration panels to line the hygienic
parts of the building and form the new cold stores; also install the internal and
cold store doors and stainless steel wall protection panels.
• Package 6: Supply & installation of the refrigeration equipment.
• Package 7: Supply & installation of the resin floors in the hygienic parts of the
building.
• Package 8: Procurement of second-hand and new fit out equipment.
• Package 9: Consolidation and shipment of materials and specialist equipment
from the UK and Guernsey.
• Package 10: Provision of accommodation and sustenance for specialist persons
from off-Sark.

specification.
14. Unless otherwise stated or agreed prior to commencement of works,
Contractors are expected to work to the appropriate British Standard(s) for
their works.
15. Contractors should visit site prior to tendering to satisfy themselves that they
have fully understood the requirements of this tender and the drawings
provided and also identified any issues that may affect their works. Alternative
proposals may be submitted as an addendum to tenders if these result in a
better implementation, or avoid safety issues or reduce costs or time on the
project. Requests for information and clarification will be accepted prior to the
tender closing date on the basis that any information provided will be shared
with all tenderers. No claims for additional costs or time will be considered
after the award of the contract for items that the contractor could reasonably
have foreseen prior to tendering.
16. The Contractor will be required to provide public liability insurance with a
reputable insurance company to a value of £10 million for the duration of the
Works. They will be responsible for providing appropriate insurance cover for
their staff and sub-contractors. The Contractor will be required to produce
evidence of their insurance arrangements prior to commencing any work or
procurement of materials.
17. The Contractor will provide a 12 months warranty (materials, parts and labour)
on the materials and workmanship that they provide.
18. The Employer will provide monthly stage payments to the Contractor against
their itemised claims for payment. Contractors are to include a proposal for
the payment stages they require as part of their tender. (Failure to provide a
payment schedule with the tender will result in the Employer imposing a

2.2 USE OF LOCAL LABOUR.
Wherever possible and economically viable, preference will be given to contractors
who use local skills, including all building, electrical and plumbing works. If contractors
wish to bring in labour from off island they must include the number of persons and
duration of the imported labour as the Employer will negotiate a rate with a local
provider to provide bed, breakfast and evening meals for all visiting persons for this
project. The cost of accommodation is not to be included in tenders for the Building
Works.
2.3 TIMETABLE AND COORDINATION WITH OTHER CONTRACTORS.
Time will be of the essence for these works as no slaughtering can take place during
refurbishment of the slaughterhouse. It is a condition of tendering that contractors
agree to work with more than one contractor on site at any one time and to coordinate
with each other in order to minimise the down time of the slaughterhouse. The
Contractor’s attention is drawn to item 5 in section 2.1 above.
The Contractor is to provide a provisional timetable for their works outlining the key
stages that they propose including lead in time. It is anticipated that the works will be
undertaken in January and possibly extending into February 2018, this being the
period when there is least activity in the slaughterhouse.
2.4 DRAWINGS.
The following drawings are provided. Contractors should satisfy themselves that they
fully understand the drawings prior to tendering.

2.5 GENERAL NOTES
The walls and ceiling of the change area, services enclosure, slaughter area, cold stores
and butchers’ room will be lined out with purpose made refrigeration type panels.
These panels and the associated accessories, doors, frames, protection panels,
sealants and specialist installation persons will be sourced separately. Building works
within these areas need only to be rough finished on the interior surfaces as these will
be covered by the panels.
The Contractor is to allow for stripping out all existing fit out in the area of the works
as well as the new works as described below and shown on the drawings.
Sark Abattoir tender invitation and user specification (Building and services package).
Re-issued: 27th July 2017

The Contractor is to include for fixing the specialist free issue items as detailed below.
Equipment which is fixed to the wall is to be sealed using a proprietary bonding sealant
(Stelmax 1961 or agreed equivalent). This sealant will be free issued by the Employer
to the Contractor. The Contractor will be given instruction on the use of this sealant
when they assist with the installation of the specialist refrigeration panels. (See
section 2.6 below). SILICONE SEALANT MUST NOT BE USED ON ANY ACCOUNT
UNLESS SPECIFICALLY AGREED WITH THE EMPLOYERS CONSULTANT AS SILICONE
HAS BEEN SHOWN TO BE INADEQUATE FOR THESE APPLICATIONS DUE TO PEELING,
DISCOLOURATION AND DIRT PICK UP OVER TIME.
Wherever possible fastenings are to be hidden so they do not create a dirt trap in
working areas. Rivets must not be used. Where exposed screw heads cannot be
avoided in working areas they should be sealed over to facilitate cleaning wherever
possible using the approved sealant.
The building works required are as detailed below. Where required, the Contractor is
to include for all digging out and foundations to provide a sound structure.
A costing schedule is provided as part of the tender package which is to be submitted
as part of the Contractor’s tender.
2.6 ASSISTANCE WITH THE INSTALLATION OF THE REFRIGERATION PANELS,
INTERNAL DOORS AND WALL PROTECTION PANELS.
Specialist suppliers and installers will supply and install the lining panels to the walls
and ceilings in all the “white areas” as designated below under a separate contract
from the building works. They will also install the cold store and internal “white area”
doors and the stainless steel wall protection panels. The Building Contractor will price
for skilled building or carpentry labour plus an assistant, an access tower and a fork
truck or tele hoist to offload the panels and doors at site. All these items will be made
available on a daily basis as given in the schedule of costs to assist with the panel
installation and to provide transfer of this skill to Sark. The Building Contractor will be
required to provide basic hand tools (including jig saw, electric drills, etc.) with their
tradesmen.
2.7 THE EXISTING FACILITY.
Drawing “Sark Slaughterhouse 1F-01 Existing Layout” shows the current facilities.
The existing facility includes:
• Slaughterman’s change area: (In reality the old smithy with the remains of the
old fireplace, forge etc. still in place and an uneven stone floor with no washing
or changing facilities). An old oil fired boiler is located in the fireplace to
provide hot water for slaughter operations.
• Slaughter area: This has a concrete floor with a mixture of stone and masonry
walls with wooden outer doors. Plumbing services (pipework, tanks, etc.) are
located in the rafters amongst the hoists used for lifting carcasses. A central
drain is connected to an external holding tank for “green waste” (guts, blood
etc. generated during the processes immediately after slaughter). A pig
scalding tank (for removal of the hair) is located in this room. This room opens
to the butchery room. The floor can be hosed down but the walls and ceiling

are not suitable for cleaning whilst the rafter house myriad cobwebs etc. There
is a corrugated roof which is not sealed at the eaves or panel joints.
• Butchers’ room: A basic room with stainless steel tables. This has a concrete
floor, masonry walls and the same roof structure as the slaughter room.
• Cold stores: Two standalone cold stores are housed next to the butchers’ room
in a section of the building that is open on one side. One cold store is a former
military containerised cold store with a (relatively) modern split cooling
system. The other cold store is a modular type of cold store with an old split
cooling system.
• Veterinary Room: Whilst this is not part of the upgrade proposal, it does
provide a secure storage area for the slaughterman’s guns. Water and
electrical services are provided to the Veterinary Room from the
slaughterhouse
• Exterior: The exterior has no hard standing (e.g. for off-loading animals form
trailers). An old lock up container serves as the slaughterman’s tool store. The
exterior woodwork (i.e. doors, windows, barge boards, etc.) are in a poor state
of repair and the guttering and downpipes also in poor repair.

3. BUILDING WORKS.
Drawing Sark Slaughterhouse 01 Issue F – 02 Strip out and Building Works shows
the strip out and preliminary works required. Drawing “Sark Slaughterhouse 1F-05
Proposed Layout” shows the key changes that are proposed. In summary these are
as follows:
3.1.1 Slaughterman’s rest and change area:
• Remove the old boiling pan and associated brickwork.
• Replace the external door and window with white PVC. The door is to have a
vision panel, lock and weather sill. The window may be a sash type or casement
type with window lock. Glazing may be single or double glazed.
• Repair the two internal brickwork columns.
• Make good the old stone floor to provide a level, smooth concrete finish with
a new damp proof membrane. The floor under the new slaughterman’s change
and the services cupboard is to be suitable for the application of a specialist
resin floor. The resin floor and coving will be provided by specialist installers
under a separate contract from the building works. The building contractor is
to provide a concrete floor that will meet the requirements of the resin floor
installer as given in 2.2.2 below. There is no requirement for falls to the floor
or floor drainage in this area. The specialist resin floor contractor will prepare
the concrete floor for the resin application, generally by scabbling. The floor in
the general change area (i.e. the area that will not be covered by resin) will be
sealed by the building contractor to permit wet and dry cleaning. The level of
the concrete floor must match the slaughter area without a step at the new
doorway to the slaughter area.
• Form a new access door (door D2) to the slaughter room. (Doorway only
requires a lintel and rough finishing as the specialist panels and doors will line
out the finished surfaces). The building aperture size for the doorway will be
approximately 1045 mm (W) x 2050 mm (H), exact size to be determined once
the specialist doors and frames are procured.
• Prepare the walls and ceiling of the general change area for decoration.
Prepare and paint the walls and ceiling to the rest area with two coats of good
quality emulsion paint using white silk finish emulsion (or similar pale colour
to be agreed) including blinding where required over bare
masonry/mortar/concrete. Note: the walls at the slaughterman’s change and
services cupboard only need to be stable and rough finished as the finished
walls and ceiling will be provided by the specialist panel lining – see below.
• Specialists will supply and install a new slaughterman’s’ change area using
white, self-supporting lining panels to form the finished walls and ceiling with
hand washing. A new services cupboard will also be formed using the specialist
panels and door to house new hot water tanks and associated pipework etc.
(Panels, internal doors and installation to be by specialists under a separate
contract from the building works).
3.1.2 Slaughter area.
The existing slaughter area will be enlarged as shown on the drawings. The building
works required are as follows:
Sark Abattoir tender invitation and user specification (Building and services package).
Re-issued: 27th July 2017
Page 10 of 37
• Allow to remove the existing equipment that is to be retained to a storage area
within the Seigneurie farm as itemised in Appendix 1 The equipment includes
the pig scalder, all hoists and trolleys, butchers tables and all butchers’ and
slaughterman’s equipment. Also allow to return these items to the remodelled
area and fix as required.
• Demolish two walls dividing the existing butcher’s room from the slaughter
room and the cold store area. Ensure that the walls and internal roof structure
are stable by retaining small nibs in the position of the existing cross walls as
required. The doorway in the external wall to the existing butchers’ room will
be blocked up, finished on the exterior to match the existing and rough finished
on the inside. The new walls and internal nibs only need rough finishing as they
and the ceiling will be lined with new white PVC faced panels by specialists.
• Remove all of the old plumbing and electrical services from the ceiling void and
walls.
• Replace the double wooden external doors and frame with a new electrically
operated roller shutter door and frame finished in white with appropriate
weathering and protection against a marine atmosphere. Door to be operable
from inside and outside the building. 240 v motor required.
• Provide a smooth concrete floor with falls to the existing drain suitable for a
resin floor finish and coving. The resin floor and coving will be provided by
specialist installers under a separate contract from the building works. The
building contractor is to provide a concrete floor that is dry, sound and free
from surface laitance or looseness to meet the requirements of the resin floor
installer. The concrete should be a minimum 35 N reinforced concrete. The
finish should be power floated with expansion joints as required. In addition
the concrete should be laid to falls to the existing drain, the minimum fall
should be 1:80 gradient and 1:70 in wet areas from the longest distance
(diagonal). Falls should be consistent across the fall plane without undulations.
The resin will follow the contours of the substrate therefore the building
contractor should be satisfied with the concrete standard (as above) before
allowing resin application. Concrete must be less than 75% RH before resin can
be applied or 7 days old if using a suitable liquid damp proof membrane.
• The resin floor and coving will be supplied and installed by a specialist resin
floor contractor under a separate contract from the building works. The
specialist resin floor contractor will prepare the concrete floor for the resin
application, generally by scabbling.
• Supply and install new hoist rails using the “line system” to the design and
specification provided with this tender invitation (Appendix A4), re-using the
existing hoist mechanisms. One hoist rail will run into both cold stores to
enable full length carcasses to be taken into the cold stores (qv) on the rail.
Supply and install a new high level fixed hoist point over the existing drain to
the design and specification provided with this tender invitation (Appendix 4).
The hoist rails capacity and configuration will be as follows:
i. Two straight rails in the slaughter room, each of 500 kg capacity.
ii. One hoist rail of 500 kg capacity that loops from the slaughter room, through
the cold stores and into the butchers’ room. (The rail will need thermal

breaks where it traverses into the cold store to avoid thermal transfer and
condensation outside the cold stores).
iii. Three branches off item (iii), each of 500 kg capacity in each cold store.
iv. A central static support hook (not using the “line system” over the slaughter
zone to the design and specification provided with this tender invitation
(Appendix A4) with a capacity of 1 tonne (lift), 2 tonne (shock loads).
• Provision of new services (hot & cold water, electrical outlets). (See sections 4
& 5 below).
• New lighting including dimmable lights to assist with animal movements (see
section 4 below).
• The existing drainage arraignments will be retained but the Contractor is to fit
a free issue removable stainless steel removable grating to the drain (304 or
316 grade). The grid will have a frame that is suitable for integration into the
resin floor finish. The Contractor must ensure that the frame of the new drain
fitting must be securely sealed to the existing under-floor drain to avoid any
leakage. (Resin floor finish will be by others as outlined above). [Check
type/source of drain??]
• Fit specialist equipment as detailed in Appendix 1. These items will be free
issued to the building contractor at site. Items include a new tie down anchor
point to be securely bolted into the floor to restrain animals prior to slaughter,
a safety ladder in one corner and re-installation of the pig scalder.
• Specialist suppliers and installers will supply and install the lining panels to the
walls and ceiling under a separate contract from the building works. The
building contractor will price for skilled building or carpentry labour and an
access tower to be made available on a daily basis as given in the schedule of
costs to assist with the panel installation and to provide transfer of this skill to
Sark.
3.1.3 Cold Stores.
Two new cold stores will be formed positioned between the Slaughter Area and the
Butchers’ Room with access from both these areas. The two cold stores will be of
identical size and will be constructed from specialist refrigeration panels which will be
installed under a separate contract from the building works. The building works
required are:
• Remove the old ex-army container cold store to a nearby covered location
within the Seigneurie farm. Dismantle and remove the old panel type cold
store. (Others to de-commission and de-gas the old refrigeration split unit).
• Build up the existing concrete hard standing to match the level in the slaughter
room with 50 mm thick PIR or Styrofoam or agreed alternative insulation (e.g.
Kingspan or agreed equivalent) inserted within the new concrete. The concrete
is to meet the requirements of the resin floor specialist as given in 2.2.2 above.
Build up the existing concrete hard standing to match the level of the existing
concrete floor in the former butchery area with PIR or Styrofoam or agreed
alternative insulation 50 mm thick under the new concrete. The finished
concrete is to provide a drainage slope (approximately 1:100) towards the
Slaughter Room and is to be suitable for laying a resin floor (by others). No

5. MECHANICAL SERVICES AND PLUMBING.
The new plumbing works required are as follows:
• Strip out all existing pipework, tanks, the boiler and associated equipment in
the area of the works. Retain the existing oil tank and oil feed pipe.
• Supply and install a new pressurised water system.
• The existing cold water supply from the Seigneurie farm bore hole will be
retained. The cold water feed to the building will be retained and not replaced.
• Fit an ultra violet water steriliser to the main cold water supply. (See electrical
section above for details. It is assumed that the electrician will supply the UV
steriliser for the plumber to fit).
• The existing foul water drainage will be retained. (Note: the drains feed into a
lined tank under the exterior yard area: this captures the green waste from
slaughter so that it can be pumped out and processed at the Islands sewerage
works).
• Supply and install a new oil fired boiler of a similar rating to the existing boiler,
linked to the existing oil tank and feed. Include for a new circulating pump with
isolating valves and automatic air bleed; also for appropriate oil filter and feed
to the boiler with appropriate valves.
• New heating controls are to be fitted as specified in the electrical section
above.
• Supply and fit control valves for the hot water heating system to enable the
system to be controlled as stated in the electrical section above. Include for
isolating valves to permit easy replacement of control valves.
• Supply and install a single dual coil insulated low temperature hot water tank
of 500 litre capacity, located in the services cupboard in the change area. One
coil will be connected to the new oil fired boiler with appropriate controls and
the other coil will be connected to a solar heating panel. (See below for the
solar heating panel requirement). The low temperature hot water tank will be
fed from the cold water feed. Prior to using the hot water its temperature will
be boosted if required by the boiler to achieve 60oC in accordance with the UK
Health & Safety Executive advice on the Control of Legionella (HSG274/Part 2).
• A second tank of approximately 200 litre capacity with a single heating coil and
electric immersion heater will be provided in the services cupboard for high
temperature hot water. The high temperature tank will be fed with pre-heated
water from the 500 litre low temperature hot water tank and will raise the
water temperature from 60oC to 80oC. The high temperature tank will be
provided with a pump and controls to feed the high temperature water to the
Pig Scalder (see below).
• Supply and install a new solar water heating system. Two solar water heating
panels each approximately 1 m x 2m in size will be fitted to the south facing
roof of the slaughterhouse approximately above the services cupboard. The
solar panels will be of the Solar Twin type with the costed option for the
vacuum tube type. Either option will be fitted with a solar powered pump.
• The Pig Scalder is required to achieve and maintain 62 oC in use. The existing
pig scalder will be retained. This has a tank in its base with a heat transfer coil.
Sark Abattoir tender invitation and user specification (Building and services package).
Re-issued: 27th July 2017
Page 19 of 37
The Contractor will include to connect the scalder coil to the 80oC hot water
supply with appropriate pump, shut off and control valves and insulation.
• A pull out drop hose will be supplied and installed by the Contractor, located
in the Slaughter Room behind the safety ladder.
• The veterinary room will be supplied with low temperature hot and cold water
from the new slaughterhouse water systems but all of the existing fittings and
pipework will be retained unaltered in the veterinary room.
• All internal pipework is to be renewed within all areas of the Slaughterhouse
(but not the Veterinary Room). Wherever possible pipework is to be installed
prior to installation of the lining panels so it is not exposed in the rooms. Where
surface pipework is unavoidable it is to be contained in white rectangular PVC
conduit or trunking that will be sealed to the walls and with all joints sealed.
(Note: sealing to be done as described in section 2.5 above. SILICONE SEALANT
MUST NOT BE USED ON ANY ACCOUNT UNLESS SPECIFICALLY AGREED WITH
THE EMPLOYERS CONSULTANT AS SILICONE HAS BEEN SHOWN TO BE
INADEQUATE FOR THESE APPLICATIONS OVER TIME).
• All hot water pipework will be insulated with foam insulation, taped and
secured. Visible pipes will be insulated with white PVC faced insulation with
taped joints suitable for washing down.
• The new water distribution system will service all points in the facility as shown
in table 5(i) below and on the drawings. Both hot water systems should be of
the recirculating type to avoid legionella in accordance with HSG274 Part 2
Published 2014.
• Surface mounted fittings will be used where possible, sealed to the panel face.
In general fittings will be sealed to the walls using an approved sealant. (Note:
sealing to be done as described in section 2.5 above. SILICONE SEALANT MUST
NOT BE USED ON ANY ACCOUNT UNLESS SPECIFICALLY AGREED WITH THE
EMPLOYERS CONSULTANT AS SILICONE HAS BEEN SHOWN TO BE
INADEQUATE FOR THESE APPLICATIONS OVER TIME).
• Drainage from the sinks, sterilisers, pig scalder and wash stations is to be
connected to the catch tank that is used for the slaughter room.
