“…First, based on previous studies and articles we extracted effective factors on building construction accidents; then taking into account the experts' comments who were all labor supervisors and the official judiciary experts in occupational accidents in this project to screening and prioritizing the factors [parameters], and the criteria and sub-criteria has been specified. The number of optimized questionnaire was calculated by Cochran's theorem 4 . So the number of questionnaire for desirable answer was 44, in sample size 50.…”

“…Gabriel Raviv et al, 2017 in the article "AHP-based analysis of the risk potential of safety incidents: case study of carne in the construction industry" indicated that due to increase in the number of fatal incidents in construction sites related to improperly applying tower-crane, the article proposes new measures to potentially assist to prevent and minimize the related incidents with crane in construction industry [3]. Zhou et al, 2017 in an article proposed an Internet-of-Thingsbased (IOT-based) safety barrier warning system to achieve a safer underground construction site [4].…”

In this article-based on previous studies, applying a questionnaire with 81 parameters, and asking experts who mainly were labor inspectors and official judiciary experts on building construction accidents-5 crucial factors and 13 extrinsic factors effecting on building construction's safety has been identified, and then for determining the amount of effectiveness of each factors on safety with analyzing the data with AHP method 1 , and based on 3 main experts' comments. Findings: the primary criterion-the height working (H) with weight 0.438-is the primary factor in building construction accidents. The sub-criterion-falling from scaffolding (H4) with relative weight 0.433 and combined weight 0.190 takes the first rank, and lack of edges protection [unprotected edge] (H2) with relative weight 0.342 and combined weight 0.150 are put in second position. After the height working, the criterion of excavation (G) with weight 0.262 is the second factor in occurrence of accidents. The sub-criterion of digging without protection (G1) with relative weight 0.571 and combined weight 0.149 takes the third place and sub-criterion inadequate training (C1) with relative and combined weight 0.137 has the fourth position. Conclusion: according to the findings, we can clearly state that the practical approach to increase safety and avoid accidents in building construction site becomes readily obtainable by using safety equipment in height working, using protection in the edges to prevent falling, and considering more safety measures in excavation time like testing the soil resistance and the strength of neighbor buildings, and finally safety training.

Managing complex and dynamic construction projects is challenging as it relies highly on the real-time communication and seamless coordination of numerous 'things' and people that are spatially and temporally distributed at a massive scale. To deal with the associated challenges, various concepts, including internet of things (IoT), cyber-physical systems (CPS), and smart construction objects (SCOs), have been explored in construction. Amidst the increasing overlap and merger of principles among these three pervasive technologies is that clearly narrow definitions and isolated development of each field are no longer appropriate. It is, therefore, opportune for this study to explore and propose a deployment framework that integrates IoT, CPS, and SCOs, with a view to achieving greater synergy that could expedite their holistic implementation. It does so by adopting a mixed methods approach with literature review, technological analyses, case studies, and action research at the core. This deployment framework encompasses the key components of each technology (i.e. the three core properties of SCOs, the bi-directional information flow in CPS, and the extensiveness of devices and networking in IoT) in an interconnected structure while enabling the uniqueness of each technology to be evident. In addition, example application scenarios are described to demonstrate the applicability of the proposed framework in real-life practice. This study contributes to the body of knowledge by presenting a taxonomy that clarifies the similarities and differences between IoT, CPS, and SCOs when applied to the construction industry. The integrated deployment framework can be used to guide further theoretical explorations on the synergistic effects of IoT, CPS, and SCOs, and enriched with practical cases to facilitate construction project management.

“…Ultrasound waves have been widely used in the construction field. Zhou et al [24] developed an Internet-of-Thingsbased system to achieve improved safety for underground construction sites. They installed ultrasonic detectors which have the centimetre-level accuracy to construction vehicles such as excavators and dump trucks to improve safety.…”

This paper presents a conceptual framework for monitoring concrete placement and vibration operations. The proposed design is intended to enable collection and analysis of concrete pour data using computer vision and ultrasonic positioning. The system being developed alerts a project manager when workmanship observed is not in compliance with acceptable performance standards. The paper describes key operational factors in concrete placement and vibration that need to be monitored and reviews options for realtime locating systems. Fourteen factors related to concrete placement and their corresponding parameters are determined for measurement. In regard to the real-time locating systems, Ultra-wideband, ultrasonic, and computer vision technologies satisfy the expected levels of on-site positioning range and accuracy. Along with computer vision, ultrasonic technology has been chosen over Ultra-wideband alternative due to its lower cost and comparable performance.
