Adaptive, Modularized Constructions Made in a Flux

Modular construction with precast concrete elements offers significant potential for rapid and resource‐efficient building. This paper presents findings from the scientific coordination project of Priority Program (PP) 2187, addressing key challenges in the design and production chain. Generalized structural models for 1D and 2D modular structures are derived, and load‐bearing capacities of slender reinforced concrete modules are described using M/N interaction charts including geometric scatter. Production‐induced tolerances are systematically quantified and propagated to the structural level via Gaussian error propagation. For multi‐dimensional structures, a sensitivity‐based placement strategy using Elementary Effects is proposed, reducing global deformations by up to 43%. Construction sequences are optimized using Simulated Annealing, ensuring intermediate construction states do not govern final dimensioning. The convertibility of modular structures is assessed through sensitivity analysis of load redistribution. All boundary conditions are integrated into a digital twin based on the Asset Administration Shell. The findings reveal that adaptive modular construction represents a viable pathway toward industrialized, sustainable, and circular concrete construction.
