PRECAST CONCRETE ELEMENTSwww.cpi-worldwide.com CPI %u2013 Concrete Plant International %u2013 1 | 2026data. Production, in turn, provides feedback on actual geometry, reinforcement position, concreting parameters and curing conditions. This information is linked to the planning model to form a digital twin, which performs the following functions in production operations:%u2022 Simulation and preliminary testingGeometry and process simulation identifies collisions, impermissible slenderness or details that cannot be assembled before production begins.%u2022 Target/actual comparisonDeviations are detected, documented and, if necessary, automatically compensated during production.%u2022 Quality assurance and approvalData-based evidence supports approval and testing processes and reduces uncertainties associated with new reinforcement systems.%u2022 Continuous process optimisationRecurring deviations lead to learning adjustments in planning and robot parameters.The networking of digital planning, robotics and quality recording thus forms the basis for economically stable carbon concrete wall production.Economic and ecological value creation %u2013 outlook for scalingThe economic value creation of the carbon concrete semi-precast wall does not result from a single advantage, but from the superimposition of several effects along the process chain. In economic terms, these are in particular:%u2022 Cross-section and material reductionThinner shells reduce material usage and create space gains that can be monetised.%u2022 Automation advantagesLower personnel intensity, reduced error rates and more stable cycle times reduce process costs per component.Fig. 4: Direct yarn placement with deflection points and carbon yarn in LeipzigHausadresse:HOWAL GmbHAm Reutgraben 4D-76275 Ettlingen-Ew.Internet:www.howal.comEmail:info@howal.comPostadresse:HOWAL GmbHPostfach 417D-76258 EttlingenTelefon:+49 (0)72 43-9 49 73 - 0Telefax:+49 (0)72 43-9 06 45Intelligente SchalsystemeSonderschalungenTreppenschalungenSt%u00fctzen- und BinderschalungenAddress:HOWAL GmbHAm Reutgraben 4D-76275 Ettlingen-Ew.Internet:www.howal.comEmail:info@howal.comMailing address:HOWAL GmbHPostfach 417D-76258 EttlingenPhone:+49 (0)72 43-9 49 73 - 0 Fax:+49 (0)72 43-9 06 45Intelligent Formwork SystemsTilting tables and special designed mouldsStaircase mouldsMoulds for beams and columns
