Langley Academy – Detailed Specification
SECTION 1 - GENERAL CONDITIONS & PRELIMINARIES
1.1.0 PROJECT PARTICULARS
It is Langley Academy’s requirement that a fully porous ‘third generation’ synthetic grass pitch shall
be designed and constructed to suit the requirements for playing 11 and 5/7/9-a-side football
matches. The pitch shall meet the requirements of the FIFA Quality Program and FIH National.
This specification sets out the minimum requirements for the construction of a new synthetic 3G pitch
on the site of the existing grass pitches at Langley Academy, Langley Road, Slough, Berkshire SL3 7EF.
The area will be primarily for football and hockey use plus cross-field play. The pitch facility generally
would be expected to fall into the intense use category in terms of overall utilization.
The synthetic grass surface shall have dimensions 106m long x 70m wide. The synthetic grass surface
shall be line marked for a 100m long x 64m wide 11-A-Side football pitch. Cross field markings will be
specified as required.
The pitch shall have a 3 metre wide run-off area all around the pitch.
The installation work, details of which are contained in this specification, must be carried out such
that it conforms to the performance characteristics set out in the FA document – Design Brief for
Artificial Turf Pitches 2010. Notwithstanding this, the facilities to which this specification relates
should be constructed using proven methods of construction and proven materials to the highest
standards of workmanship and quality, which will give a good useable, and guaranteed, life for the
playing surface of a minimum of 8 years and guarantee of any shockpad and base works for 2 carpet
lifetimes, (minimum of 16 years). The design should take account of future maintenance requirements
of the synthetic surface. The Contractor is to provide a proposed maintenance regime and monitoring
system to ensure all guarantees and warranties remain valid at the completion of the works.
The form of construction proposed must meet all the specified requirements detailed in Section 2 and
the synthetic grass manufacturer’s recommendations. The Contractor shall provide documentary
evidence, in the form of independent test reports by a FIFA approved laboratory that the overall
construction complies fully with all the relevant performance requirements.
The Contractor shall indicate, at tender stage, the method he proposes to adopt for levelling and
preparing the formation, to ensure long-term stability of their subsequent base works.
It should be noted that the specification and design herein recognizes the existence of UK and
European registered patents for the new generation synthetic turf system (long pile synthetic turf)
and the potential of a patent infringement. The product UK patent numbers are as listed below:
2329910B / 2348890B

1.5.0 CONTRACT DETAILS
The contract is being tendered by recognised pitch contractors linked to carpet manufacturers who
are members of the FIFA Preferred Producer Scheme.
Where this document refers to the Contractor it relates to the corporate body with whom the contract
will be let. Tenderers should offer documentary proof of successful installations of the proposed pitch
system. The responsibility of the performance of the final pitch, its civil engineering make up and
surfacing, lies entirely with the contractor at all stages of the project.
In order to be considered as an acceptable pitch system the main contractor is to produce test
certificates relating to the proposed pitch system as part of the tender submission. In order to be
acceptable, the pitch system must be up to the standard set out in the FIFA Quality Program for
Football Turf and FIH National.
The artificial pitch including the sub-base and artificial carpet are to be guaranteed against failure for
a minimum of eight years for the carpet from date of final acceptance. This acceptance date will be
based on the FIFA field test. Failure will be defined as falling below the performance standards set out
in FIFA & FIH testing standards, where normal maintenance alone will not restore the pitch to that
standard.
Where main contractors wish to provide an optional variant which falls outside the specification for
below carpet build up; only pitch systems which achieve the performance standards required by FIFA
& FIH plus the requirements of the warranty, (See Para. 2.14.0) will be considered. Optional variants
will not be considered without a tender for the specified system as well.

that the inspection cannot be carried out or completed necessitating a further visit, the additional cost
incurred, including all expenses, will be borne by the Contractor.
The performance of the artificial turf depends upon the preparation of the sub-base and composition
of the existing sub-soil. Therefore the installed turf will not only be tested in the laboratory but will be
required to undergo field-testing as well.
Where materials, products and workmanship are not fully specified they shall be as recommended in

materials and have them tested for compliance with the Contractor's tender submission and this
document. Test methods to be employed will be in accordance with current practice. The Contractor
shall allow for the taking of such samples and the proper recording of the location to which the
samples relate, as directed by the Employer and detailed in the documents.
Samples for test shall be delivered within 48 hours of being instructed by the Employer. Any delay to
a scheduled inspection or preparation of a report by the Test House arising from late delivery of the
samples for test or from failure to keep proper records as required, shall not relieve the Contractor
from his responsibility with regard to completion within the Contract Period.
1.6.2 Failure of tests - Defective work

on the information provided which also forms part of these Employer’s Requirements.
2.1.4 Formation preparation:
Pitches need to be founded on competent ground. Topsoil, turf and vegetation are not suitable and
therefore must be stripped from the site. The area of the works shall be stripped of all vegetation and
topsoil to a depth of at least 300mm, the exact depth to be determined by reference to trial hole/s
recorded during any ground investigation survey.
The formation shall, after preparation of the sub grade drainage and before the laying of an
appropriate geotextile membrane, have been fine-graded by the Contractor to a surface tolerance of
+/- 10mm relative to the design levels. Any soft, loose or damaged materials shall be excavated and
backfilled as required or directed by the Client’s appointed agent. The finished formation should have
a California Bearing Ratio of (CBR) 5%.
The formation shall be free from slurry and mud and will have no areas of freestanding water.
Where areas fall outside of the given tolerances the contractor will be required to trim the formation
back or augment the shortfall with sub-base materials this will be at the contractor’s expense.
The formation shall not be left continuously exposed to rain or be uncovered overnight. Under no
circumstances shall construction plant or other traffic use the exposed formation.
The ground shall be trimmed and levelled using cut and fill as required. All filling should be carried out
in layers not exceeding 150mm thickness, and each layer should be compacted to the requirements
of BS 1377:1990, before the next is spread.
Any soft spots shall be excavated and replaced with imported crushed rock, free from detritus
material, in accordance with the Department of Transport Specification for Highway Works (Class 6F1
or 6F2).

Langley Academy – Detailed Specification
This will be achieved by undertaking the following steps:
•
•
•
All products manufactured must submit a certificate of compliance to the effect that the
product dispatched is the same as the product submitted for type testing in accordance with
procedures to be run under their IEC 17025 1999/ISO 9002 or similar scheme. These
certificates must be dispatched and have been received by the institute before any product
leaves the place of manufacture for the installation site
If the testing institute has any reasonable cause for concern, it may request samples of the
manufactured products for product identification
Any minor change in the product profile must be proven to satisfy the requirements of the
scheme. Any significant change will require a complete re-evaluation of the product
All the equipment used must be registered within those procedures. It is not sufficient to only have
certain pieces of equipment complying with the demands and not others.
Furthermore the same pieces of apparatus must be utilised in both the laboratory tests and the field
tests to ensure consistency. Variations on equipment cannot be accepted. The test institutes must
provide the appropriate certification to verify this and that the certification is maintained.
The Test Institutes must also provide evidence of the experience of all the staff that would be used to
undertake the testing. The use of inexperienced casual staff is not acceptable.
Testing of the synthetic pitch should be undertaken by a test house that is:
•
•
•
•
Accredited as a FIFA testing house
Accredited by the United Kingdom Accreditation Service (UKAS) or other recognised
accreditation services or the relevant sport governing body
The chosen laboratories must therefore be within the ISO schemes ISO/IEC 17025 1999 and
ISO 4502
A member of SAPCA’s Professional Services Group
2.13.2 Sampling
An artificial surface is defined as the total system including the support layers.
Therefore the testing of the surface will occur both within a Laboratory environment (type testing)
and upon the completed installation. Certification according to ISO 17025 is a requirement. A product
will undergo a series of tests to establish its suitability for installation.
Once installed the performance requirements together with the construction requirements will be
checked. Only a product that has completed both the laboratory and field-testing will it have filled the
requirements of this specification. Accordingly only the fully certified pitch will be considered
completed upon the return of successful testing certificates from a recognised artificial sports pitch
testing house.
