Thus, this paper aims to review existing studies on CPS and DTs for CB to propose a comprehensive system architecture that considers human-environment interactions.\u0000\u0000\u0000Design/methodology/approach\u0000Scientometric analysis and content analysis were adopted for this study.\u0000\u0000\u0000Findings\u0000The scientometric analysis of 1,042 journal papers showed the major themes of CPS/DTs for CB, and these can be categorized into three key technologies to realize CB in the AECO community: CPS, DTs and cognitive computing (CC). Content analysis of 44 relevant publications in the built environment assisted in understanding and evidently confirming the claim of this study on the integration of CPS and DTs for CB in construction by also involving the CC. It is found and confirmed that CB can be realized with CPS and DTs along with the CC. A CB system architecture (CBSA) is proposed from the three key technologies considering the human-environment interactions in the loop. The study discovered the potential applications of the CBSA across the building lifecycle phases, including the design, construction and operations and maintenance, with the potential promise of endowing resilience, intelligence, greater efficiency and self-adaptiveness.

This study uses data augmentation at test time and adds outlier samples to training set to prevent over-fitted network training. For data augmentation at test time, five segments are extracted from each sample image and fed to the network. For these images, the network outputting average values is used as the final prediction. Then, the proposed approach is evaluated on multiple deep networks used as material classifiers. The fully connected layers are removed from the end of the networks, and only convolutional layers are retained.\u0000\u0000\u0000Findings\u0000The proposed method is evaluated on recognizing 11 types of building materials which include 1,231 images taken from several construction sites. Each image resolution is 4,000 × 3,000. The images are captured with different illumination and camera positions. Different illumination conditions lead to trained networks that are more robust against various environmental conditions.

The automated detection of material will aid to monitor the quality and see whether the right type of material has been used in the project based on contract specifications. In addition, the proposed model can be used as a guideline for performing quality control (QC) in construction projects based on project quality plan. It can also be used as an input for automated progress monitoring because the material type detection will provide a critical input for object detection.\u0000\u0000\u0000Originality/value\u0000Several studies have been conducted to perform quality management, but there are some issues that need to be addressed. In most previous studies, a very limited number of material types were examined. In addition, although some studies have reported high accuracy to detect material types (Bunrit et al., 2020), their accuracy is dramatically reduced when they are used to detect materials with similar texture and color.

The main strengthening methods of reclaimed coarse aggregate are physical strengthening, chemical strengthening and gradation strengthening through comparative analysis, more effective strengthening methods are not single, but a combination of two or more methods. Effectively combine gradation strengthening and chemical strengthening, can better improve the mechanical properties of recycled concrete coarse aggregate and durability. There is little research on the failure mechanism of transition zone and strengthening the interface transition zone of recycled concrete, and there are few literatures about harmless treatment of chemically strengthened slurry.

The article presents a review of the literature on the use of different types of fibers in asphalt mixture, including natural fibers, synthetic fibers, and glass fibers. The mechanical properties evaluated include stiffness, fatigue resistance, crack resistance, and rutting resistance. The review highlights the potential benefits of using fiber in asphalt mixture, including improved stiffness and crack resistance, reduced rutting, and increased fatigue resistance.

It involves the management of waste material arising from construction, renovation, and demolition activities as such concrete, timber, steel, and plastics products. The poor construction waste management practice has led to failure to ensure sustainability in construction by increasing environmental impacts and illegal dumping. Hence, with proper construction waste management techniques and processes, the notion of sustainable construction can easily be achieved. The aim of this study is to identify the initiatives for construction waste management toward sustainable construction. The study adopted a quantitative method of questionnaires survey distributed to 118 numbers of Grade 7 Contractors in Pahang. The professional teams in the company provide their responses in regard to waste management initiatives taken by them. The findings revealed several initiatives taken by contractors in helping to move towards sustainable construction in Pahang as such strengthening the policies in government agencies regarding waste management and compliance with the law to the general legislative structure.
