Groundworks for a Multi-Use Games Area, including: Preliminaries Excavation and foundations Base construction Paths Hard and soft landscaping The works shall be carried out in accordance with the requirements of the specifications within this Schedule of Works and the contract documents. In the event of discepancy the Schedule of Works shall take precedence. Quantities stated within this Schedule can be relied upon by the contractor. All volumes stated are unbulked. Tenders should be based on the details included in the following document bundle: a. Sky Revolutions drawing reference SRL221552 [Topographical Survey] b.

BEI Lighting drawing reference 28670-1 [Floodlighting columns] m. Philips Lighting Optivision LED gen3.5 Information Sheet [Datasheet 2026 January 10] All references to "the tree protection plan" shall mean PJC document reference PJC/6393/24-02. All references to offsite disposal shall be understood to mean disposal at a registered waste transfer station at the Contractors expense. Duty of Care waste transfer notes will be made available for inspection by the Project Manager or Client upon request. Contractors should visit the site with the Project Manager prior to preparing or finalising their tender to inspect the baseline condition of the site. The new vehicular access onto Copthorne Bank will be used as the sole access to the working area. Assume that work will be done during prevailing dry weather and no temporary road or grass protection will be required. Project Manager to be advised immediately if prevailing weather is likely to result in more than superficial wear to grass surface or mud being carried from site on wheels. All tarmac surfaces within the site must be protected where trafficked by vehicles with a gross weight in excess of 7.5 tons. Preliminaries: Contractor to allow for the preparation of a Construction Phase Plan aligned with the approved project CEMP. Contractor to allow for the erection of Heras fencing to secure the north of the site from the field gate adjacent to the play area. Dust netting to be fixed to Heras fence on western and northern perimeter of play area. Pedestrian entrances on western and eastern boundaries to be closed. Root Protection Areas of trees and hedgerows within the vicinity of the working area as shown on the root protection plan to be fenced. Contractor to allow for appropriate welfare facilities for number of operatives on site. Contractor to allow for the accurate setting out of the Multi Use Games Area (MUGA) in accordance with the contract drawings using GNSS (GPS) and/or total station survey equipment. Contractor to allow for all other preliminaries required for the project: Excavation and foundations: Scrape off grass to a minimum depth of 50mm from footprint of MUGA, surrounding path and embankment areas and remove from site [1050m2] Excavate minimum of 150mm top soil from footprint of MUGA, surrounding path and embankment areas and remove from site [1050m2] after retaining adequate top soil to dress all embankments with 150mm layer [Area - 182m2]. Excavate subsoil to form reduced levels within to levels to be agreed with the Project Manager. Allow for excavation, loading, removal from site and disposal of 452m³ of material based on 50 no. export loads (expected export loads have been based on 9m3 out of the ground per load). Provide waste transfer notes and disposal tickets to the Project Manager as evidence of the number of loads removed from site. The item cost shall be reduced by £420.00 per load where fewer than 50 export loads are removed. Should it become apparent during excavation that the volume of material requiring removal from site will exceed 50 loads / 452m³ the contractor will immediately notify the Project Manager and not proceed with disposal beyond this allowance without further instruction. Raise levels initially using suitable material retained from the excavation works where approved by the Project Manager and then by imported Type 3 clean primary aggregate as necessary to achieve the proposed formation levels. Allow for the placement and compaction of 242m³ of fill material. Material shall be placed in layers and thoroughly compacted as work proceeds. The rate is based on the import of 242m³ of Type 3 clean primary aggregate equating to 532.4 tonnes using a conversion factor of 2.2 tonnes per m³. The rate is based on £50.84 per tonne. The item rate shall be adjusted by £50.84 per tonne based on the actual quantity of Type 3 aggregate imported with the quantity evidenced by delivery and weighbridge tickets provided to the Project Manager. Any variation shall be calculated by reference to the difference between the actual imported tonnage and the allowance of 532.4 tonnes. Excavate foundation 600mm wide x 400mm average depth x 58m long on line of perimeter path edgings on northern end of pitch with 18.5 returns sloping at 1% on each side of the pitch and remove soil from site. Allow for one 225mm step in each side foundation. Lay 600mm x 300mm deep x 58m C25 concrete foundation with reinforcing bars inset to suit spacing of 215mm jollow blocks. Form one 225mm step in foundation on each side of MUGA. Lay 215 hollow blocks in one course [45m] and two courses [58m] and fill voids with concrete. Base construction: Lay total thickness of 300mm MOT Type 3 clean primary aggregate on non-woven geotextile in properly consolidated 100-150mm thick layers to form base for asphalt base layer [780m2 x 0.3m - 234m3]. Install checkdams as work proceeds in accordance with Pluviam design. Lay total thickness of 250mm MOT Type 3 clean primary aggregate on non-woven geotextile in properly consolidated 100-150mm thick layers to form base for asphalt base layer [780m2 x 0.25m - 195m3]. Paths: Set 50 x 150mm PCC edgings [manufactured in accordance with BS EN1340] to form edge of perimeter path [total length 134.5m]. Edgings to be bedded on minimum 100mm deep x 300mm wide ST4 concrete foundation and haunched to within 50mm of top of back edge. Lay 150mm thick layer of fully compacted Type 1 clean primary aggregate conforming to SHW Clause 803 & BS EN 13285 on non-woven geotextile membrane [Area 86m2]. Hard and soft landscaping: Dress all embankments with 150mm layer of previously retained topsoil and ensure levels finish flush with top surface of perimeter path edgings. Spread general purpose grass seed on freshly laid top soil [182m2]. ## Contract award
