The 3D form­work bodies that give the con­cre­te its shape are plan­ned, pre­fa­bri­ca­ted and assem­bled with com­pu­ter assis­tance. The more geo­me­tri­cal­ly com­plex the form­work, the more flowa­ble and at the same time pres­su­re-resistant the con­cre­tes used have to be. In this con­text, spe­cial high-per­for­mance con­cre­tes are often used for sta­ti­cal­ly rele­vant com­pon­ents; in the case of the rhi­no enclo­sure, a red-colo­red con­cre­te was used. Most of the form­works at Glass are com­plex one-offs, and they can no lon­ger be rea­li­zed eco­no­mic­al­ly with con­ven­tio­nal machi­nes, neither in terms of accu­ra­cy nor speed.
