Description of the goods or services required
The proposed development site is located at:
Olchfa Comprehensive School
301 Gower Rd,
Sketty,
Swansea
SA2 7AA
The rugby/football pitch layout is shown on drawing GTC00642 SK01 Rev B. The works are to include, but not
Construction of an 115 x 75m WORLD RUGBY, IRB Clause 22 & FIFA Quality standard 3G
Rugby / Football pitch. Accreditation to World Rugby Regulation 22 and EN 15330-1
The proposed development area is located directly to the south of the school buildings. The
proposal is to convert and existing natural turf training area into a 115 x 75m 3G synthetic turf for
rugby which is also suitable for football use. The pitch will have a goal recessed end for goal storage.
The intention is to connect a new pitch drainage system into this outlet chamber with a restricted
discharge rate. Attenuation of drainage water will be undertaken in the stone sub-base used as a
formation to the pitch construction.
The site investigation has shown that there is a layer of potentially expandable slag material present
close to the existing surface. A proportion of this material may need to be removed off site and it is
classified as hazardous waste. A provisional sum allowance has been made if this is required. The
Earth Science Partnership geotechnical investigation has shown that the slag material has the
capacity to expand by approximately 1% when wetted for a prolonged period. They have therefore
recommended that the material is covered with an impermeable membrane to reduce the risk of
any expansion.
The appointed contractor will therefore be required to design and install an impermeable membrane
system to be installed over the formation and through the drain lines and under fencing. The area
to be covered is the pitch and goal storage area footprint including the external mowing strips.
Pitch drainage water will need to be attenuated under the pitch footprint therefore the membrane
will need to be totally impermeable to prevent ingress of water into the underlying slag material.
The installation of a 250 lux LED floodlighting system and 5 m high rebound fencing will be required.
