NPC Cropping 17,000 Piles at Agratas Giga Battery Factory
Some 17,000 piles have been driven into the ground to help stabilise the foundations of the new Agratas EV Giga Battery Factory in Bridgwater, Somerset, England. The development of Building One – the first of 3 – is being undertaken by Balfour Beatty and 2 of its subcontractors, Synergy Plant and Toureen Plant, on behalf of principal contractor, Sir Robert McAlpine. National Pile Croppers (NPC) has been commissioned to supply and support an array of hydraulic pile croppers to work on this strategically vital development. Agratas is the global battery business of the Tata Group. It designs, develops and manufactures high quality, high performance, sustainable battery solutions for multiple applications. The company’s new UK EV Giga Battery Factory, located in Bridgwater, will produce 40 GWh/y of battery cells, enough to supply approximately 500,000 passenger vehicles. The gigafactory, once operational, will be one of the largest in Europe, and will initially make batteries for Jaguar Land Rover. Due to the enormity of the plant, it will also supply other car manufacturers as well as producing commercial energy storage. It is estimated that the factory will by the end of 2027 supply 40% of the UK domestic market. As well as supplying the car industry, Agratas also plans to create batteries for other applications and develop commercial energy storage solutions. Sir Robert McAlpine was awarded the contract for the pre-construction work on the former Royal Ordnance Factory site. Under the phase one proposals, Building One will be constructed at the western edge of the site. Construction will be completed in phases, with battery production set to begin in 2027. The project is estimated to be worth around £4 billion ($7.4 billion), with Building One set to cover 244,710 m2 of developments. Due to the time scale of the project, as well as its sheer size, specialist sub-contractors have also been retained. These include Balfour Beatty, Synergy Plant, groundworks contractor Kelston Sparks, and Toureen Group. The sheer size of Building One and the 2 other developments, and the speed in which construction of the site is planned, has meant that a huge number of concrete piles are being used. These are of a variety of sizes and designs depending on the specific use of the pile. Due to the intense project demands with its demanding time schedule, the contractors realised that they would need to call on the services of a company who would be able to supply a plethora of pile cropping equipment and also be able to support the croppers 24/7. To this end, National Pile Croppers was engaged directly by Balfour Beatty via Synergy Plant and Toureen Plant. At present, many thousands of concrete piles are in the ground with many more to follow. Synergy Plant has been using a National Pile Cropper supplied Power Cropper, whilst Toureen Plant 6 Power Croppers, 2 Multi Bar croppers and a PC400. The attributes of the equipment are truly being put to the test, working around the clock in order to meet the demanding schedule. The piles that have been cropped so far are 275 mm pre-cast, with the piling mat for Building One being approximately 1,000 m x 750 m. When the work is completed on Building One, the contractors will move onto Building Two which is currently at the groundworks stage. In addition to the pile croppers outlined, the contractors are also trialling a ground breaking National Pile Croppers development. This has been designed to ‘nibble’ at the concrete piles prior to cropping due to the tight nature of the gaps between the concrete piles. This solution has been developed to improve efficiency, productivity and safety on site. The National Pile Cropper Power Cropper is currently proving to be the all-round workhorse on the development, being used by both Synergy and Toureen Plant. This has been designed to be constructed of lighter and stronger materials which has meant that its weight is minimized. Its small dimensions enable easy movement around the site. National Pile Croppers will be hard at work throughout a good portion of 2025. 17,000 concrete piles take some cropping, but the features found, and the manufacturing excellence of the croppers, as well as the round the clock support, will help ensure that the Agratas EV Giga batter factory is completed on time to enable production to begin in 2026.
