“…All the challenges and constraints related to cementitious mixtures are easily carried over to any conceived material/mixture intended for 3DP, not only because of its particular properties (shape, grain size, density, porosity, water absorption, elasticity, plasticity, hardness, fluidity, mechanical strength, thermal conductivity) but also due to the slow development of 3DCP technologies when it comes to creating robust, autonomous, and versatile extrusion systems that allow the replacement of components to extrude different mixtures. Consequently, all the inherent research and investigation is a trial-error process until a balance is reached [151].…”

The integration of waste materials in extrudable cement mixtures has the potential to make the construction industry more sustainable by reducing carbon footprints and developing eco-friendly materials. This along with advancements in 3D concrete printing (3DCP) provides engineering and architectural benefits by reducing material waste and costs. In this paper, the impact of waste incorporation on properties of mortar and concrete is examined. The use of waste materials, such as pumice, coal slag, agricultural lignocellulosic residues, and recycled rubber tyres, to improve thermal insulation and durability of cementitious composites is discussed. In addition, the incorporation of air-entraining admixtures with surfactant activity is explored for their indirect effect on thermal behaviour, pore size reduction, and enhancement in concrete properties. This review includes important topics such as a strength resistance to freezing and thawing, fire resistance, plasticising effect, and delay in cement hydration. These findings highlight the benefits of using diverse waste materials in construction, providing a multidimensional approach to waste management, cost optimization, and enhanced construction materials in the context of 3DCP.

“…The printable cementitious material can be the key issue in 3D printing construction projects [33]. It is difficult to define a constant supply of raw materials for 3D printing construction projects [34]. Apart from materials, the transportation of 3D printers is another difficult and costly issue for construction project decision-makers [22].…”

“…It is known that most 3D printing projects are limited to smaller scales [61], and remote housing is a revolutionary idea at this stage. The thermal and green benefits of using 3D printing in building construction were discussed by Guimarães et al [34,45], but Thomas [62] examined the societal costs and benefits of 3D printing from a monetary and resource consumption perspective. These studies constitute a small portion of the current 3D printing research, which proves there are ample opportunities for future studies.…”

“…This construction mode also allows extra rooms to be easily attached to existing houses [60], which makes housing more sustainable. As for environmental significance, the construction industry is one of the highest resource consumers [34]. Many researchers have identified the potential of 3D printing technology in reducing material consumption and waste generation [22,59].…”

With the development of new construction technology, increasing attention is being paid to 3D printing due to its construction efficiency as well as its sustainability. Numerous researchers have determined its benefits in cost reduction, resource savings, safety assurance, etc. Although various advantages have been identified, there are limitations and challenges in technology implementation. Especially since it is a new construction method, 3D printing construction projects will have a very different supply chain compared to traditional projects. As part of a research programme investigating the 3D printing construction supply chain in a New Zealand context, this study systematically analysed the research about 3D printing adoption and supply chain challenges in the construction sector. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was adopted as the guideline for literature selection. PRISMA is designed to assist researchers in reporting the review research focus and methodology, and examining the findings from published literature. NVivo was then adopted to code and analyse the selected publications to gather the data necessary for our study. The literature was analysed from the perspectives of the research focus, research methods, and findings. Studies about 3D printing implementation, benefits and barriers, as well as its significance are also analysed. As a result, this research found existing research gaps, including the fragmented situation of management-related research in the 3D printing construction sector, insufficient research in top management for 3D printing construction implementation, and changes to supply chain management practices in 3D printing construction projects. A decision support system demo for supply chain management is drafted in this paper, which requires further study. The research outcome highlighted the existing studies in 3D printing construction implementation and supply chain, and initiated a research topic on supply chain decision making. The result contributes to the theoretical and practical development of 3D printing technology in the construction industry. This review paper also inspires future studies on supply chain frameworks and theoretical models.

“…With the increasing demand for sustainable development in society, the civil engineering field is also facing higher requirements and challenges [6][7]. Intelligent civil engineering based on Building Information Modeling (BIM) has become a key means to achieve sustainable development, and the introduction of BIM provides more accurate and comprehensive project information for civil engineering, which makes project management more efficient and reduces the waste of resources [8][9].…”

Currently, in China, intelligent construction research predominantly targets engineering projects, with limited focus on the benefits of Building Information Modeling (BIM) technology. This paper advocates for integrating BIM with cutting-edge engineering construction techniques, adhering to four intelligent construction level assessment principles. We introduce a benefit evaluation model for innovative construction, combining the two-dimensional cloud model with the Analytic Network Process (ANP) hierarchy method. Our findings highlight the significant role of BIM in enhancing operation and maintenance efficiency and in the deepening of design, evidenced by average scores of 4.0868 and 4.0691, respectively. Early stages of innovative construction projects benefit from BIM’s effective material usage control, reducing initial material consumption below planned levels. Furthermore, our analysis reveals BIM’s capacity to simultaneously optimize quality cost provision and additive cost, with Project 1 showcasing optimization indexes of 7.91% and 73.38%, respectively. These results underscore BIM’s substantial impact on improving the economic benefits of intelligent construction.
