“…At this point, it is not a human, but a landbased robot that invades the leakage area, and the cause can be found out. People can operate remotely through the robot arm of the land robot [21,22]. (6) Agricultural application: equipped with a special camera, it can not only obtain low altitude information of diseases, pests, and weeds but also drive small-scale pests and diseases.…”

In recent years, with the steady and rapid growth of the national economy, various industries have developed rapidly and the resulting fire accidents have also been on the rise. This study mainly discusses the control system of a fire rescue robot for a high-rise building design. Robot fire detection method involves obtaining the video image of the fire detection area through a high-definition camera, performing image preprocessing on the current frame image of the video in the robot operating system to obtain the image; and performing the flame area segmentation based on the Ohta color space and the Otsu threshold segmentation algorithm on the image, to obtain the segmented image; through the interframe difference method, the preprocessed image of the previous frame is subtracted from the current frame image and the moving area of the image is segmented to obtain the segmented image; the obtained segmented image is combined with the segmented image in the robot operating system and images are intersected to obtain a segmented image with the characteristics of flame motion; based on other characteristics of the flame, flame recognition is performed on the area in the segmented image. Fires in high-rise buildings are increasing gradually, which seriously endangers the safety of human life and property. The firefighting robot and its control system play an important role in the fire protection of high-rise buildings. The purpose of this study is to analyze the disaster relief effect of a firefighting robot and control system in high-rise buildings. In this study, we use MATLAB software to model and simulate the rescue situation of a firefighting robot in high-rise buildings. The fuzzy control system established in the fuzzy logic toolbox of MATLAB can easily replace human field work and can change the control rules and membership function in the FIS editor. The results show that the rise time and adjustment time of the system are basically the same under the condition of variable load stiffness. The maximum overshoot is 0.59%, and the steady-state error is 0.19%. The maximum overshoot is 1.0148%, and the stability error is 0.46%. It is concluded that the expert PID algorithm is efficient and practical. It can be concluded that the robot position control system adopts PID control algorithm, and the attitude control system adopts expert PID control algorithm. This research provides some value for the development and design of firefighting robots in high-rise buildings in the future and also brings important significance.

“…Project document reviews (S 25 ) can enable EPC contractors to identify problems with documents including cost reports, drawings, and specifications in time and better coordinate with the implementation of design optimization [40]. Errors in the materials provided by the owner (S 26 ) [41] and the approval efficiency of design documents (S 27 ) [40] may affect the implementation of design optimization.…”

Design optimization can influence the achievement of management goals and the sustainable development of EPC (engineering–procurement–construction) projects. Current research regarding engineering design optimization mainly focuses on the technology aspect, while lacking extensive attention regarding the factors influencing stakeholders’ participation in design optimization of EPC projects. Based on the existing literature and expert opinions, this study identifies 33 critical influencing factors and adopts the DEMATEL (decision-making trial and evaluation laboratory) and ISM (interpretive structural model) method to analyze the hierarchical structure and interrelationships among these factors. The results show that the factors, including subcontractors’ participation during the design, design management level, performance evaluation mechanism, technological development, owners’ attitude towards disputes, and sensitivity to project cost growth, play critical roles in multi-stakeholders’ participation in design optimization of EPC projects. All these factors can be divided into causal factors (13) and result factors (20) and a hierarchical structure model is developed for the whole system, composed of three types of influencing factors, that is, the surface direct factor, intermediate indirect factor, and deep-rooted factor. The findings of this study can help managers to have a better understanding of design optimization of EPC projects from the stakeholder perspective and help managers to take effective measures to improve the status quo as well as facilitate the sustainable development of this kind of project.

“…(peer-to-peer) technology (Chen and Hou 2014). The association of BIM with PMIS integrates miscellaneous design information, which is crucial for building construction (Whang et al 2016). However, the implementation of BIM interface systems involves technical, administrative, and legal issues (Singh et al 2011).…”

As a disruptive information and communication technology (ICT) in the architecture, engineering, construction, and operation (AECO) industry, building information modeling (BIM) enables project teams to manage a project via a modelbased cooperative approach. Although it has a widespread impact on the industry, the systematic implementation of BIM in projects faces challenges. This study integrates BIM into the life cycle of a building project with the introduction of a conceptual framework constituted by BIM Information Flow, BIM Model Chain, BIM Workflow, BIM Institutional Environment and BIM-based Project Management Information System (PMIS). This conceptual framework identifies the key areas for integrating BIM into the project life cycle and explains how BIM works for project management practice. Through an ethnographic action research approach, the study develops a BIM roadmap for the project life cycle by systematically implementing BIM in the building project. The major findings and pieces of evidence derived via the implementation support the conceptual framework. The following discussions explain how BIM disrupt the project from the perspective of organization design and clarify the contributions of this study in project management as well as BIM adoption and integration. Finally, the conclusions focus on the development of this research, the role of the conceptual framework to underlie the BIM roadmap, and the research This is the Pre-Published Version. https://doi.org/10.1061/(ASCE)ME.1943-5479.0000647 limitations. Recommendations are provided towards future research works.
