b'Partner News Summer 2020 29CorporateIntroducing: BAM NuttallNew IET Corporate Partner BAM Nuttall are part of the Royal BAM Group, one of Europes largest construction companies employing 20,000 people globally, with an annual turnover of 7 billion. Projects range from road, rail and airports, to marine, tunnelling, and energy schemes.BAM, with partner Weber Beamix, is actively exploring the implementation of 3D concrete printing using parametric design to make elements that can be combined into structures such as bridges, retaining walls, drainage outlets, street furniture and even skate ramps.The design is printed using a concrete mortar mix, pumped through a nozzle mounted on a robotic arm, delivering layers of mortar and incorporating a stainless steel wire to increase durability and strength. The first factory in Eindhoven has capacity to deliver large-scale projects in controlled conditions, which ensures a high-quality product. Under development is a flying factory concept, enabling the facility to be deployed closer to projects.BAM has used the technique to make a number of bridges in the Netherlands, including the worlds first 3D printed cycle bridge, and is currently printing the worlds longest 3D concrete printed bridge to be located in Nijmegen.quantities.
