DESCRIPTION OF WORKS
The existing pitch is a sand-over-gravel suspended water table construction, with a block
irrigation system operating 54 x Rainbird 8005 sprinklers using eight stations with up to seven
sprinklers operating per station (Appendix 1). Specific features are:



a flat playing surface
approx. 300 mm of sand rootzone overlying a 100 mm deep layer of 2-5 mm gravel
a lateral pipe drainage system running across the width of the pitch at a spacing of
approx. 4 m, connecting to a series of manhole chambers on either side of the pitch.
Material underneath the gravel layer is at least 1 m of fill containing boulders. As-built drawings
of the drainage system and finished levels are shown in Appendices 2 and 3.
The existing sward cover shall have been removed to approx. 40 mm depth and a new irrigation
system installed and commissioned by others. The exposed upper rootzone layer shall have
been amended with organic matter (approved compost or peat) and zeolite to assist moisture
retention, nutrient retention and biological activity and the grass cover re-established by others.
An eight week grow-in period has been allowed (by others). Rootzone sand will also have been
excavated around the perimeter of the pitch to replace that taken off during removal of the
existing sward cover, and a new concrete kerb installed by others together with basecourse
material for the foundation of the artificial turf perimeter.
Note that the finished surface of the pitch shall mirror the shape of the sub-base layer and all
layers of the profile shall comprise a constant depth of material.
This Contractor shall install a boundary of artificial turf and shockpad between the concrete
kerb and the perimeter block paving over the basecourse that will have been installed by others
according to the drawings.
Following installation of the stitched turf reinforcement system under this contract, the
Contractor shall then undertake operations to maintain the turf and keep it at the specified
standard for a period of 12-months.
The pitch must be available for play and have achieved a full reinforced grass cover for the start
of the 2016/17 football season and the first match to be hosted by the stadium on 18 August
2016.
The Contractor shall be required to supply maintenance labour as part of this Contract for
managing the maintenance of the natural turf pitch and artificial turf surrounds. The Client will
be responsible for supplying equipment and consumables for the 12-month maintenance
period. However, this does not absolve the Contractor of his duty of care to ensure that the
maintenance equipment and consumables are appropriate and suitable for the requirements
of the Contract. In this respect, the Contractor shall inspect and assess the condition of the
machinery and equipment currently available for pitch maintenance and shall make
recommendations and cost proposals to the Client regarding the purchase of additional

Shockpad (this contract)
A system incorporating a FIFA-approved pre-fabricated shock pad shall be used. Shockpad
installation shall be pre-cast, unless otherwise approved by Client’s Representative. The
recommended nominal thickness shall be 20 mm. The shockpad shall be installed according to
the manufacturer’s instructions, using rolls of maximum length to minimise the requirement for
jointing. Note that the edge of the shockpad must finish above the concrete kerb of the pitch as
opposed to finishing flush with the edge of the concrete kerb.
The Contractor will allow for the development of method statements for laying the shockpad. If
alternative products are used, the Contractor will allow for the supply of technical data sheets
and method statements to be approved before commencement.
Laying of the shockpad onto the dynamic base shall avoid the creation of any creases or
wrinkles. The Contractor shall specify the method by which they intend to join sections of
shockpad (e.g. taping or glue). Any jointing method used shall be continuous. Junctions, edges
and day joints must be free of lips or edges.
The Contractor shall ensure that the shockpad layer, once installed, is not damaged and that
the surface is maintained in a clean condition prior to installing the artificial turf carpet.
B5.6
Carpet and Infill (this contract)
The Contractor shall supply and install an approved 3G, sand and rubber granule filled, artificial
turf surface over the area shown in the Drawings.The approved long pile 3G artificial turf shall
have a proven track record of use under Middle East conditions and be laid on a suitable
dynamic base. The artificial turf perimeter shall be safe and sustain safe use by players, security
staff, ball handlers and operatives who may from time to time traverse this zone. The artificial
turf system shall meet the FIFA Quality Pro standard.
The Contractor shall supply a sample of the proposed product and a technical data sheet for
the artificial turf surface they propose to install, including, but not necessarily limited to, the
following items: type of yarn material, dtex value, pile weight, pile height, stitch rate, no. of
stitches per m 2, no. of tufts per m2, type of primary backing material, type of secondary backing
material, total product weight, length of guarantee and method of jointing the seams and any
other information that may helpful in evaluating the suitability of the artificial turf (e.g. FIFA
approved laboratory test report).
The infill materials shall be a proprietary mixture of uniformly graded fire retardant rubber
granulates or a combination of sand/rubber particles blended to form a stable matrix to the
artificial turf carpet. There shall be no rubber dust or excessive shred in the bulk materials
supplied. The Client’s Representative reserves the right to reject suspect rubber. The infill
materials shall be inert, i.e. they must not leach out contaminants which would find their way
into local water courses, drains or affect users playing on the surface.
The Contractor shall supply a technical data sheet for the supply of sand and rubber infill they
propose to use for approval prior to installation. The type of sand and rubber infill shall meet
the requirements of the artificial turf supplier’s specifications in terms of material source (SBR
or EPDM), particle size grading, angularity/hardness and depth of rubber infill.
The artificial turf carpet shall be installed according to the manufacturer’s instructions, and shall
be supplied in rolls of sufficient lengths to minimise transverse jointing across the surface. Each

section of artificial turf laid shall be free of any creases or bubbles. Joints shall be completed
according to the manufacturer’s specifications and instructions.
At the boundary between the natural and artificial turf systems, the artificial turf shall be folded
over the shockpad overlying the edge of the concrete kerb and shall be recessed into the profile
by approx. 150 mm. The turf shall be laid flush with the block paving on the other side. On
completion the artificial turf edge shall provide a stable playing surface which shall not display
any lateral movement or curling under normal playing conditions. The finished artificial turf level
shall marry in imperceptibly with the adjoining natural turf surface and block paving perimeter,
with no discernible change in elevation.
The edges of the surface must be permanently fixed where appropriate to the underlying
surface by continuous gluing or similar approved method so that the edges of the turf do not lift
up and become damaged or prone to health and safety concerns.
Sand and rubber granule in-fill shall be uniformly distributed into the artificial turf carpet in
separate operations using a mixing ratio and methodology as recommended by the
manufacturer (e.g. by using a continuous-belt drop spreader or other approved machinery) and
then finally worked in and groomed according to the manufacturer’s recommendations.
Upon completion of installation of the infill, the artificial turf surface shall exhibit its required
performance characteristics as specified in Section B3.3.11.
B5.7
Coordination with Pitch Contractor
The Contractor must liaise with the Pitch Contractor regarding the precise depth of
shockpad and infill material so that the height of the concrete kerb can be set. Note that
Pitch Contractor shall have installed temporary wooden edging to retain the height of
rootzone around the concrete kerb. This edging shall be removed by the Contractor (not
Pitch Contractor) prior to installation of the artificial turf carpet.

TURFGRASS ESTABLISHMENT (BY OTHERS)
The surface shall be established from sprigs of Bermudagrass Tifway 419 or other approved
cultivar.
Sprigs consisting of rhizomes, crowns and only a few green leaves are most desirable. The
time interval between harvest, delivery and spreading shall be kept to an absolute minimum.
Sprigs shall comprise healthy living stems, stolons, or rhizomes and attached roots of locally
adapted grass without adhering soil, including two to three nodes and from 100 to 150 mm long.
Sprigs shall be obtained from heavy, dense certified sod as classified in the TPI GSS.
Sprigs shall be procured from a supplier and shall have been grown under climatic conditions
similar to those in the locality of the project. Harvesting and planting operations shall be
coordinated to prevent exposure of sprigs to the sun for more than 30 minutes before covering
and moistening. Sprigs containing weeds or other detrimental material or that are heat
damaged will be rejected.

Sprigs shall be protected from drying out and from contamination during delivery, on-site
storage, and handling. Protection from exposure to wind and direct sunlight shall be exercised
until planted and sprigs shall not be stored for longer than 24 hours or on concrete or bitumous
surfaces.
Prior to spreading of sprigs, the starter fertiliser specified in Section B8.3.2 shall be uniformly
spread over the surface and the fertiliser lightly washed into the surface using the irrigation
system.
Sprigs shall then be broadcast uniformly by hand, with mechanical equipment, or other
approved method. Sprigs shall be planted at a minimum of 600 bushels1 per acre (approx. 5
litres/m2). The Contractor may elect to use a greater quantity of sprigs if they wish at their cost
in order to meet the handover objectives of this project.
Sprigs shall be planted to achieve a minimum number of 60 viable sprigs per square meter.
The distance between individual sprigs shal be a maximum 150 mm. Sprigs shall be forced into
the soil to a minimum 25 mm depth by disk-rolling, pressing with steel matting, or other
approved method.
The entire area shall be firmed with a roller not exceeding 130 kilograms per meter roller width.
A minimum 25 percent of the installed sprigs shall extend above the ground surface upon
completion of the sprigging operation.
A grow-in period of 8 weeks shall then be carried out (by others).

TURFGRASS MAINTENANCE
B8.1
General
Between the last fixture on 18 May 2016 and the start of the new season on 18 August, the
upper profile of the existing pitch is to be renovated, the irrigation system replaced and an
artificial turf perimeter installed as well as a hybrid stitched reinforcement system.
During this period the surface is to be grown in and established using Bermudagrass sprigs
before transitioning to cool season grasses (perennial ryegrass) for the main playing season.
B8.2
Irrigation
Irrigation shall be applied to ensure satisfactory maintenance of the grass surface. Run-off,
puddling, and wilting shall be prevented. As the new grass surface becomes established the
frequency of irrigation shall be adjusted, according to the weather conditions, to encourage the
development of a dense vigorous rooting system.
A hand held soil moisture probe shall be used to monitor conditions within the top 65 mm of the
profile. Soil moisture content shall be maintained no lower than 15% and no more than 30%.
Major repair and routine servicing of the irrigation system shall be carried out by a specialist
irrigation company if the Contractor does not have the necessary in-house skills for this work.
The Contractor shall be responsible under this Contract for the day-to-day maintenance of the
irrigation system. However, the Contractor shall also build into their tender regular inspection,
servicing and testing of all irrigation components by a specialist irrigation company if the
Contractor does not have the necessary in-house skills for this work.
The Contractor shall ensure that at least one person working on this Contract has a sound
knowledge of the type of irrigation system operated at this Stadium and is skilled in the basic
servicing of minor components. This shall include the servicing of sprinklers, valves and
changing of sprinkler heads and nozzles.
The Contractor shall ensure that irrigation system is operating correctly at all times. In order to
achieve this, the Contractor shall run the automatic pop-up system every month on a test cycle
for at least two minutes duration and visually check the following items:









all sprinklers pop up
all sprinklers rotate and rotate at the same speed as each other
all sprinklers retract correctly
nozzles are not blocked
sprinklers are not leaking
no leaks (wet patches on the pitch)
sprinklers are set at the correct levels (flush with surface level)
sprinklers are aligned correctly (vertically)
sprinkler nozzles are of the correct size
Page 30 of 46

19/05/2016
Sammy Ofer Stadium
In addition the Contractor shall during the course of its duties monitor the overall performance
of the system including the function of the quick coupler valves. Any defects or problems
including sprinkler replacement, major leak repairs, controller system malfunction or potential
damage to turf through the operation of the irrigation systems shall be reported to the Client on
the day on which they are identified.
B8.3
Fertiliser Application and Nutrient Management
The Contractor shall maintain the nutritional health of the turf using a combination of the routine
maintenance fertilisers specified below. The application of fertiliser in general shall be timed so
that it brings the pitch to a peak condition for any major competition or event which may be
notified to the Contractor.
Fertiliser shall be applied evenly using a rotary spreader and watered well into the turf on
completion. Applications of fertiliser potentially can be expected to be made approximately
fortnightly on average during the 12-month maintenance period depending on the type of
fertiliser used.
All fertilisers shall be uniform in composition, free flowing where relevant and suitable for
application with approved equipment. Fertilisers shall be delivered to the site in their original
packaging with legible intact labels showing guaranteed nutrient analysis.
The fertiliser programme must be devised by the Contractor to ensure a ‘little and often’
approach to nutrient management and shall be dependent upon environmental conditions and
the rate of turfgrass growth. For the first 12 months following initial pitch sprigging, the
Contractor can anticipate that fertiliser inputs will be significantly higher than for a pitch with an
established mature turfgrass sward, as follows:
Nutrient
Approximate annual
requirement (kg/ha/yr)
Approximate annual requirement
(kg/ha/yr)
First year of establishment
Second and subsequent years of
establishment
Nitrogen (N)
600-900
450-600
P2O5
150-225
110-150
K20
450-675
350-450
Fertiliser must be washed in using the irrigation system immediately after application.
Furthermore, fertiliser should not be applied in the middle of the day when conditions are hot
and sunny, but preferable early morning or late afternoon (ideally under overcast conditions).
Mowing should be postponed by two days after fertilising so that there is minimal pick up of
fertiliser granules.
Most of the above fertiliser for the first year of establishment needs to be applied between June
and November inclusive. In this respect it is recommended that 450 kg/N/ha is budgeted for
over this six month period.
The following types of fertiliser approved for use include, but are not necessarily limited to:
Page 31 of 46

19/05/2016
Sammy Ofer Stadium
B8.3.1 Base fertiliser (N-P2O5-K2O) – cultivated throughout the 100 mm deep upper sand rootzone
layer (by others)
12-12-17 + 2 MgO (or approved equivalent), applied at a rate of 250 kg/ha.
Triple Super Phosphate 0-46-0 (or approved equivalent), applied at a rate of 250 kg/ha.
Regen-R-8 6-7-4.2 (or approved equivalent), applied at a rate of 300 kg/ha.
B8.3.2 Starter fertiliser (N-P2O5-K2O) – surface applied and lightly cultivated into the top 25 mm
before sprigging (by others)
Andersons 19-26-5 (or approved equivalent), applied at a rate of 200 kg/ha.
B8.3.3 Routine maintenance fertilisers (N-P2O5-K2O) – surface applied during the grow-in and
maintenance period
A programme of routine maintenance fertiliser applications shall be determined by the
Contractor. As a guideline, the grow-in fertiliser programme shall be based on applications of
slow release and conventional release fertilisers providing a balance of NPK nutrients in the
ratio of 4N:1P2O5:3K20 or 9N:1P:6K). The fertiliser chosen must include trace elements (TE) or
else a proprietary trace element fertiliser must also be applied at recommended rates.
Fertilisers shall be sourced locally and shall be for specific use on turf surfaces. Suitable
suppliers include, but are not necessarily limited to, the Haifa Group.
A list of fertilisr products and their rate and timing of application shall be prepared by the
Contractor for approval by the Client’s Representative. Typical formulations include, but are not
necessarily limited to:
25-6-19 controlled release fertiliser
20-4-20 + 2MgO + 1Fe controlled release fertiliser
21-0-0 ammonium sulphate conventional release fertiliser
13-0-46 potassium nitrate conventional release fertiliser
Fully water soluble crystalline fertilisers may be applied as a foliar spray,
In practical terms, it is recommended that the pitch is never fertilised with a conventional release
product that supplies more than 40 kg/N/ha per application and with a concentration greater
than 21%N. Urea (46% N) may be used subject to approval by the Client’s Representative.
Soil nutrient testing to 75 mm depth shall be carried out six monthly for the first 12 months from
establishment by a recognised soil testing service provider. The Contractor shall modify their
programme of maintenance fertilising based on the results of the soil tests and from specialist
advice if so required by the Contractor (the latter at the Contractor’s expense).
Results each soil test shall be submitted to the Client’s Representative for consideration and
approval prior to fertilising programme adjustments being undertaken.
The cost of soil testing and the preparation of the fertilising programme shall be included in the
relevant Bill of Quantities.

B8.4
Fungicides, Herbicides and Insecticides
The Contractor shall supply a list of readily available pesticides to be used during the
maintenance period for approval by the Client’s Representative. The Contractor shall allow for
any herbicide, fungicide or pesticide treatments necessary to maintain the quality and health of
the turf during the maintenance period.
All such treatments shall be undertaken strictly in accordance with manufacturer’s
recommendations and relevant Health and Safety legislation.
Treatments to control weeds, diseases and pests should be applied using selected chemical
treatments that are registered for use on Bermudagrass and perennial ryegrass as appropriate.
For the 12-month maintenance period, the Contractor can anticipate in the region of monthly
fungicide applications, and annual or biannual pesticide and herbicide applications, based on a
programme of preventative and reactive fungicide applications from the supplied list of
approved products.
B8.5
Bare Patches
Any areas that have failed to establish shall be re-established by transplanting mature plugs of
turf from other areas on the pitch into the bare areas, taking care not to displace turf
reinforcement fibres.
B8.6
Sand Topdressing
For the 12-month maintenance period the Contractor shall allow for the application of up to 50
m3 of approved topdressing sand for renovation purposes, applied in multiple small applications
followed by brushing.
B8.7
Mowing
No more than one third of the upright grass foliage should be removed at one time and
allowance shall be made for cutting at least two times per week or more frequently if grass
growth demands. Care shall be required to avoid scalping the grass during early establishment.
The mower should have a well-sharpened blade to produce a clean cut without tearing or
damage to the leaf blade. All clippings shall be removed at all times.
Cutting units on all mowing machinery shall be sharp and properly set so that they cut the sward
cleanly and evenly. This may necessitate a cutting speed at the slower end of the
manufacturer’s recommendations, in order to achieve the desired presentation (eg. 5-6 km/h),
depending on the number of blades per reel. As a general guideline, it is expected that all reel
cutting units will be no less than 6-bladed reels. Rotary mowing shall be used as required to
‘clean up’ the pitch after games and matches.
The Contractor shall ensure that all movements of machinery, whether mowing, turning or in
transit, do not damage the pitch or its appearance (i.e. scalping, skidding, wheel ruts, lifting turf
etc.). The pitch shall be reinstated at the Contractor’s expense should such damage occur.
Page 33 of 46
© STRI Ltd
19/05/2016
Sammy Ofer Stadium
The majority of turning of machinery shall be expected to take place on the artificial turf
boundary in order to minimise damage to the natural turf surface. The Contractor shall take
particular care to ensure that the artificial turf perimeter area and hard surfaces are left clear of
clippings at all times.
The Contractor shall ensure that the perimeter artificial turf boundary is not damaged by natural
turf mowing activities. In this respect, it may be necessary from time-to-time to cut the turf right
on the boundary between the two surfaces using a weed eater or pedestrian rotary mower as
appropriate.
B8.8
Verti-cutting and Scarifying
The Contractor shall determine a programme for verti-cutting and scarifying the pitch surface
to remove decaying plant material, improving circulation around the crown of the turf plant and
ensuring that surface greasiness is adequately dealt with. More aggressive scarifying with the
Universe rotor of the Koro Field Topmaker shall be carried out as a renovation activity only
when the grass is actively growing and there is sufficient time for recovery (e.g. from spring to
mid-summer).
As a guideline, verti-cutting should be carried out during periods of active growth every two to
four weeks, with scarifying being carried out at renovation (e.g. end of May).
The intensity and frequency of verti-cutting and scarifying will be very dependent on the amount
of thatch accumulation, schedule of events, turfgrass condition and specific recommendations
from the turf reinforcement installer.
No verti-cutting or scarifying shall be carried out under periods of turfgrass stress (e.g. peak
summer temperatures) or when the surface conditions are too damp. All material removed
through the verti-cutting and scarifying process shall be removed.
Allowance should be made for routine verti-cutting operations (e.g. monthly) and one annual
renovation scarifying operation during the maintenance period.
B8.9
Rolling
The pitch may require flat rolling from time-to-time beyond that which can be provided by regular
mowing. The Contractor shall allow for rolling the pitch in two directions using a tractor-mounted
2.4 m wide roller (or similar approved) when conditions dictate during the maintenance period.
B8.10 Aeration/Profile Decompaction
A programme of regular aeration shall be determined by the Contractor using approved
machinery. As a guideline, the aeration programme should be a reactive one, which means that
it should be used in response to certain surface conditions and events scheduling (e.g. aeration
should be carried out as soon as the majority of the surface has dried out after an event and
leading into the next event).
The Contractor shall allow for Verti-draining the pitch to 175 mm depth using 18 mm solid tines
to relieve compaction.
Page 34 of 46
© STRI Ltd
19/05/2016
Sammy Ofer Stadium
The Contractor shall allow for shallow-aerating the pitch to 75 mm depth using a Toro Procore
840 or approved equivalent. Allowance should be made for routine aeration operations during
the maintenance period as conditions dictate.
All irrigation infrastructure (sprinkler heads, valve boxes etc) shall be marked out on the surface
prior to aeration, to avoid accidental damage.
B8.11 Maintenance Period (12 months)
In terms of the 12 months maintenance after grow-in handover, the Contractor shall be
responsible for developing and implementing a comprehensive and sustainable turf
maintenance and operations programme for turf management, which includes operation of the
artificial lighting rigs, turf fans and irrigation system, to the satisfaction of the Client’s
Representative. This programme shall take into account the planned type, frequency and
intensity of use for the stadium, as well as the unique micro-environment within the stadium
pitch bowl.
There will be a requirement to transition between grass types (warm and cool season) during
this period when weather conditions and planned fixtures allow (see Section B6.12). The
Contractor shall be fully experienced in transitional techniques and make allowance for this in
his maintenance programme and associated costs.
B8.12 Pitch Oversowing
Seed used for oversowing the pitch during the ‘winter’ months shall be made up of the following
mixture by weight:
25% approved tetraploid perennial ryegrass cultivar
25% approved creeping perennial ryegrass cultivar
with the remaining 50% being made up of two approved cultivars of conventional diploid
perennial ryegrass.
Sowing rate shall be the least required to get adequate cool season grass cover and preferably
no more than 450 kg/ha.
Sowing shall be carried out using a specialist seeder at a time agreed with the Client’s
Representative.
B8.13 Artificial Turf Maintenance
The artificial turf surface shall remain clear of debris, chemicals, stains, grass clippings, moss,
weeds and any other forms of foreign matter which could degrade the condition and
appearance of the surface.
All maintenance and repair activities for the artificial turf shall comply with recommendations
and approval of the artificial turf supplier.
The boundary of the artificial turf system shall at all times marry seamlessly with the natural turf
boundary. In this regard, ‘seamless’ means less than 2 mm under a 300 mm straight edge.
Traffic on the artificial turf perimeter (and on the natural turf surface) not associated with routine
turf maintenance activities being carried out under the direct control of the Contractor shall be
Page 35 of 46
© STRI Ltd
19/05/2016
Sammy Ofer Stadium
managed using an agreed traffic management plan between the Contractor, the Client and the
artificial turf supplier.
Note that because the artificial turf perimeter abuts the natural turf playing surface, there will
be a significant potential for natural turf products (fertiliser, sand topdressing, grass clippings
etc.) to fall on the artificial turf surface. Hence the requirement to keep the artificial turf clean
will be far greater than on a dedicated artificial turf pitch.
The following activities can be anticipated as part of the routine maintenance programme:







weekly brushing and litter/debris removal
six-monthly inspection of perimeter drain sumps and cleaning out if required
match preparation brushing for presentation as required according to the schedule of
events
quarterly de-compaction and infill redistribution using specialist machinery approved by the
manufacturer
quarterly chemical treatment for moss, algae weeds with chemical and application as
approved by the manufacturer
quarterly chemical disinfecting with disinfectant and application as approved by the
manufacturer
bi-annual formal inspection of seams and general condition
All use of the artificial turf boundary for vehicular access around the field shall be approved in
advance by the Contractor and the Client. Note that vehicles or equipment shall not be left
standing on the artificial turf surface.
The Contractor shall be aware of the load bearing capacity of the artificial turf boundary, and
shall make an assessment, in conjunction with the supplier, as to when additional turf protection
is required for non-conventional vehicles and static loads wishing to access the pitch area (e.g.
stage structures etc).
B8.14 Goal Post Management and Line Marking
Goal posts and sockets shall be supplied by the Client. The Contractor shall install and remove
goal posts as appropriate in accordance with the code and standards requirements of the
relevant sport. Prior to installation the Contractor shall inspect sockets and anchors to ensure
that they are in good and safe operating condition. Any damaged components shall be reported
to the Client’s Representative. Care shall be taken by the Contractor during the process of
installation of the posts to avoid damage to the posts or components. Any damage caused by
the Contractor to the posts/components during this process shall be repaired at the Contractor’s
cost. The Contractor shall store any ground socket caps removed during the installation of goal
posts and replace these when removing goal posts as required.
The Contractor shall at the end of each relevant event remove the goal posts if required, and
place and secure them in storage locations as directed by the Client’s Representative. The
Contractor shall exercise care during the removal and storage of the posts in order to avoid
damage. Any damage caused by the Contractor shall be repaired at the Contractor’s cost.
Ground socket caps shall be placed in the sockets immediately after removal of the posts. Any
repair work required on the goals shall be reported to the Client’s Representative. The
Contractor shall replace any ground socket caps in the sockets within one working day following
removal of the posts.
The Contractor shall regularly monitor the condition of goal posts during the season and advise
Page 36 of 46

Sammy Ofer Stadium
the Client’s Representative immediately of any unsafe or insecure goals, goal posts and
components.
The Contractor shall set out and mark the pitch according to the Schedule of Events following
notification from the Client’s Representative.
Following initial line marking, the Contractor shall maintain the markings in a clearly visible,
accurate manner to sporting code requirements for the duration of that event.
Marking shall be undertaken using only proprietary marking material of a type approved by the
Client’s Representative. Herbicides or growth regulators shall not be used to assist the longevity
of line marking.
B8.15 Non-sporting Events
The Contractor shall be required to manage the surface to host and recover from non-sporting
events such as concerts, weddings, conferences and community events. Such management
shall include, but not necessarily be limited to:



liaison with the Client’s Representative to determine the specialised maintenance needed
to protect the playing surface and minimise the risk of surface damage (e.g. preventative
fungicide application, hiring of a turf protection system)
implementation of the specialised maintenance prior to and during the event
recovery and/or repair of damaged areas after the event
B8.16 Reporting
The Contractor shall provide a monthly report to the Client’s Representative that shall include,
but not necessarily be limited to, the following sections:

Although not an exact science, it has been calculated that an optimum of six SGL MU360 1000
watt type lighting rigs (or approved equivalent) and associated accessories needed for
connection and use will be required to meet the target light levels set for the management of
the turfgrasses on the stadium pitch. Two SGL MU50 type smaller rigs (or approved equivalent)
are also recommended for managing localised turfgrass growth in very high wear areas such
as goalmouths.
Note that the Client does already own some lighting rigs. It will be the Contractor’s responsibility
to assess the condition of the existing lighting rigs and make a recommendation to the Client’s
Representative for the purchasing of additional rigs so that a full complement of lighting rigs is

B9.2
Assisted Air Movement System
The enclosed nature of the stadium significantly restricts natural air movement which can
encourage disease activity and adversely impact upon turfgrass health. To help compensate
for these difficult growing conditions, it is envisaged that eight fans will be required to encourage
air movement across the surface. The purpose of the fans is to eliminate dependence on strong
winds making their way inside of the stadium and allow for the manipulation of wind conditions
inside the stadium to provide the plant with the optimum growing conditions.
The Client shall be responsible for the purchase of the eight fan units, with the Contractor being
responsible for developing and implementing an operational plan for the fan units to the
satisfaction of the Client’s Representative.
The fan units shall be portable and easily maneuvered in to the stadium and be able to operate
from a variable position. The fans shall deliver maximum surface aeration and cooling with
minimal power use and motor noise. The fans shall be energy efficient and of a durable steel
construction, complete with covers for protection when stored.
All supply and installation works, equipment and materials shall comply with statutory and other
regulations, Codes of Practice and Standards (in particular BS7671), including Israeli wiring
regulations. Note too that it is imperative that the Contractor liaises with the electrical engineers
responsible for the building management system of the stadium to ensure that a suitable
electrical supply is installed and sockets are located at strategic points within the stadium for
where the fans will be used.
Suppliers for the fan units include, but are not necessarily limited to:

The localtion and operation of the fan units shall ensure that there are no gaps in the air
coverage of the turf. The portable, trailer mounted fans will provide the ability to place the fans
at any location around the pitch and also the ability to easily store them out of sight during any
type of event that is held at the stadium. The fans on the trailers shall be moved either with a
utility vehicle or golf cart.
