Three-dimensional (3D) printing in the construction industry is growing rapidly due to its inherent advantages, including intricate geometries, reduced waste, accelerated construction, cost-effectiveness, eco-friendliness, and improved safety. However, optimizing mixture composition for 3D-printed concrete remains a formidable task, encompassing multiple variables requiring comprehensive trial-and-error experimentation process. Accordingly, this study used seven machine learning (ML)...

The construction sector is a major contributor to global greenhouse gas emissions. Using recycled and waste materials in concrete practical solution address environmental challenges. Currently, agricultural widely used as substitute for cement the production of eco-friendly concrete. However, traditional methods assessing strength such are both expensive time-consuming. Therefore, this study uses machine learning techniques develop prediction models compressive (CS) rice husk ash (RHA) ML...

Since the 1980s, smart buildings have aroused interest of researchers. However, there is still no consensus on what intelligence a building is, and enhances that intelligence. The purpose this paper to identify correlate main drivers systems buildings, by associating them with beneficiaries: users, owners, environment. To these we carried out comprehensive, detailed, interpretative literature search. From selected articles, sorted information, extracted concepts knowledge, and, finally,...

This paper presents a multi-product, multi-period construction supply chain model, accounting for supplier capacity and material demand uncertainties. Robust optimisation is adopted to address model Research questions proposed are focused on: i). back-up sourcing backordering decisions' sensitivity associated cost factors, ii). effects of the inventory system on overall risk management. The answers these provide valuable insights enhancing resilience chains informative general contractors....
