In the construction industry, the design of dimensions of structural elements and material properties is generally separated from the design of material composition and of the production processes used. Such divide is enabled by robust construction materials (like concrete) little affected by production processes if minimum precautionary measures are in place. The same does not hold true for special concrete types; whose higher sensitivity to the mix design and manufacturing compels a shift towards more comprehensive approaches that incorporate the production process into a holistic design. The design driven by integrated numerical simulations encompassing from production to the long‐term performance is already ordinary in the manufacturing of plastic and metallic components. Nevertheless, it remains an alien to the construction industry. The objective of this paper is to review existing studies that might underpin this holistic design approach in construction and show some of its capabilities. Advanced modelling strategies available to simulate the behaviour from the fresh‐ to the hardened‐state are discussed for the cases of pervious concrete and fibre reinforced concrete. This approach provides a deeper insight about the material behaviour and aids to a new level of numerical optimisation of their compositions and production processes, unlocking a potential transformation of the modus operandi of the construction industry.
