A case study towards assessing the impact of mixed reality-based inspection and resolution of MEP issues during construction

Despite advances in 3D clash detection during preconstruction, mechanical, electrical, and plumbing (MEP) installations are still prone to the detection of unforeseen clashes during construction. These issues must be resolved as quickly as possible to prevent significant schedule delays. Through interviews and field observations, this case study investigates the impact of mixed reality (MR) on the inspection and resolution of field-detected MEP issues from product, organization, and process (POP) perspectives. For the product impact, preliminary findings from the field interviews show that MR-based inspection would increase the quality of MEP installation by identifying errors easily and resolving them faster. For the organizational impact, we modeled and compared the current (as-is) and MR-integrated (to-be) MEP field issue resolution workflows using Business Process Model and Notation (BPMN) and determined that MR-based inspections can decrease the coordination overhead between MEP engineers and superintendents by up to 75%. This translates into at least a 50% faster resolution of an MEP issue for the process impact. The paper contributes to the practice of MR-based field inspection by providing a method to quantify potential time savings by integrating MR into the MEP field issue resolution workflow and field interview questions for MEP engineers and superintendents to further examine the use of MR during inspection activities in construction projects. Our observations of MEP superintendents and engineers during field inspection showed that not all building information visualized in MR is useful for their inspection tasks. We developed a classification for building information usefulness to help construction project managers who are deploying MR determine useful information for the task at hand that needs to be integrated into the 3D MR model for MR-based inspections.

Application Research of the Project Bid Evaluation Model Based on MATLAB

Bid evaluation, an important part of bidding activities, is the most critical part to determine the quality of bidding. For large volume and complex technology projects, the comprehensive evaluation method is usually used in China. It is known that the selection of bid evaluation method has a great influence on the quality of bidding. In the face of the basic situation of China, although the comprehensive evaluation method is basically competent for the bidding work, it still has the defects of human factors in the evaluation of the bid. Therefore, it is essential to improve the bidding evaluation method. This paper mainly evaluates the bid evaluation activities of construction projects based on the comprehensive weighted evaluation method. Through the accumulation of relevant theoretical and practical research results, the author sorts out the advantages and disadvantages of various evaluation methods and analyzes the scientificity, fairness, and practicability of the established project bidding as well as the evaluation model in the evaluation of bidders through the actual project bidding and evaluation case. Combined with the mathematical model and case analysis, the bid evaluation activity is solved by the computer program, and the conventional bid evaluation results and the mathematical model evaluation results are compared to get more accurate bid evaluation results.

Bimbingan Teknis Kompetensi Manajemen Proyek Untuk Kompetensi Tambahan Calon Lulusan Universitas Iqra Buru

A construction project is one of the activities in which the results of the work are affected by the productivity of the workforce. Activities in construction projects are interrelated, so that if one activity is hampered it will hinder other activities in the field. Likewise construction activities are complex jobs and require more attention in their implementation. The elements that are part of the construction are cost, quality, and time in which there are also resources that must be controlled, such as work and materials. Based on this, it is necessary to have technical guidance for prospective civil engineering graduates to prepare them so that they are better prepared and able to enter the world of construction work later. Based on this, the Ministry of PUPR, the Director General of Construction Development, Jayapura Region VII Construction Services Center, and Iqra University, work together to carry out technical assistance activities in the Auditorium Room of Iqra Buru University, Namlea Regency. This activity lasted for 3 days. There were several materials presented, namely Project Management, K3, Quality Control and Precast Concrete. The activity participants consisted of more than 30 students, the majority of whom were final students who were doing their thesis and were about to graduate. This activity is carried out with lectures, giving assignments and questions and answers. This is done so that students are more focused on listening to the material and activities that are taking place.

Factors Influencing Scheduling Activities of Construction Projects

While construction projects continue to grow rapidly every year, the industry still faces challenges in the form of underperformance as the result of inefficient project management. This is reflected in low productivity and cost and time overruns for construction projects. Better planning and scheduling are important in order to increase the success of construction projects. This study aimed to investigate factors influencing scheduling activities of construction projects in Indonesia. A systematic literature review was performed, leading to the identification of twenty factors influencing scheduling activities at the planning stage and twelve factors influencing scheduling activities at the implementation stage. Questionnaire surveys were distributed to obtain the primary data in this study. Following data collection, factor analysis was conducted to discover comprehensive underlying concepts influencing scheduling activities. Six groups of factors influencing scheduling activities at the planning stage and three groups influencing scheduling activities at the implementation stage were identified. These findings were synthesized to develop a framework. Therefore, this study contributes by identifying key factors influencing scheduling activities in both planning and implementation stages through factor analysis within a context-specific environment and presenting the scheduling-dispute framework as a practical tool for managing delay-related disputes that may arise due to these factors. Construction professionals can take advantage of this study to implement better scheduling practices and minimize construction disputes; such improvements ultimately lead to project success.

Construction inspection & monitoring with quadruped robots in future human-robot teaming: A preliminary study

Construction inspection and monitoring are key activities in construction projects. Automation of inspection tasks can address existing limitations and inefficiencies of the manual process to enable systematic and consistent construction inspection. However, there is a lack of an in-depth understanding of the process of construction inspection and monitoring and the tasks and sequences involved to provide the basis for task delegation in a human-technology partnership. The purpose of this research is to study the conventional process of inspection and monitoring of construction work currently implemented in construction projects and to develop an alternative process using a quadruped robot as an inspector assistant to overcome the limitations of the conventional process. This paper explores the use of quadruped robots for construction inspection and monitoring with an emphasis on a human-robot teaming approach. Technical development and testing of the robotic technology are not in the scope of this study. The results indicate how inspector assistant quadruped robots can enable a human-technology partnership in future construction inspection and monitoring tasks. The research was conducted through on-site experiments and observations of inspectors during construction inspection and monitoring followed by a semi-structured interview to develop a process map of the conventional construction inspection and monitoring process. The study also includes on-site robot training and experiments with the inspectors to develop an alternative process map to depict future construction inspection and monitoring work with the use of an inspector assistant quadruped robot. Both the conventional and alternative process maps were validated through interview surveys with industry experts against four criteria including, completeness, accuracy, generalizability, and comprehensibility. The findings suggest that the developed process maps reflect existing and future construction inspection and monitoring work.

A Dynamics System of Modelling for Construction Development

The construction industry is one industry that contributes significantly to a country’s economic growth. A construction project is successful if the implementation meets the three components namely the cost, time and quality. Project financing is one of the important components in the construction project activities that define how much budget should be provided in a construction project activity. Cost components used for feasibility studies, design alternatives are possible, and the selection of optimal design in a construction project. Inaccuracy in analyzing construction costs can have a negative effect on the entire construction process and all parties involved. A system dynamics approach is a simulation method in solving real-world problems to describe relationships among variables in complex real systems. The expected results from this research are quantitatively in the form of reinforced concrete work costs which are influenced by direct costs and indirect costs that can be updated in real-time. From the simulation results, a graphical analysis through the model output will be obtained and all the resulting scenarios can be compared. In addition, with sensitivity analysis through model scenarios, it can accommodate all possible deviations that will occur in the future, including risk factors in the future.

Exploring the Cloud Computing Implementation Drivers for Sustainable Construction Projects—A Structural Equation Modeling Approach

Sustainability aspects should be adopted during all the decision-making stages of executing construction projects to gain maximum benefits without compromising the objective of such projects. Cloud computing has been a valuable tool for sustainable construction success in several countries over the last two decades. Cloud computing and its drivers have undoubtedly improved the sustainable success target of cost, quality, and time. However, cloud computing implementation in Nigeria’s construction industry is minimal. Consequently, the study aims to generate a decision support model to support a cloud computing implementation by looking into the relationship between cloud computing drivers and construction activities in Nigeria. This study’s data was obtained from previous literature and quantitatively augmented with a questionnaire survey. The data was obtained from questionnaires administered to one hundred and four construction practitioners in Lagos State. Thus, exploratory factor analysis (EFA) was used to validate the questionnaire survey results. However, to assess and validate the factors (drivers) constructed and analyze the relationships between cloud computing drivers and construction activities, partial least square structural equation modelling (PLS-SEM) method was used. An analysis of construction project activities was carried out through EFA, and it generated five main components: pre-contract stage, management, design and storage, estimation and communications, and finally, back-office activities. The study indicated that the implementation of cloud computing drivers had a significant impact on construction activities. The findings also revealed a weak relationship between cloud computing implementation and construction activities, with a 0.087 percent impact. Furthermore, the findings indicate that human satisfaction is the primary factor influencing cloud computing deployment, followed by organization, client acceptance, and industry-based factors. The significance of the findings can be used as a reference or standard for decision-makers to base their decisions on the cost efficiency of cloud computing and its capability to boost efficiency in the construction sector. This research contributes to current construction engineering management by enhancing knowledge of cloud computing implementation drivers and their implications on construction activities.

Spatiotemporal distribution characteristics, causes, and prevention advice of fatal geohazards in Jiangxi Province, China

Fatal geohazards result in severe losses of life and property worldwide, thus urging many large-scale studies of such geohazards. Further research on hotspots prone to fatal geohazard identified in national-scale studies is critical for government geohazard prevention. It has been pointed out that more detailed small-scale (sub-national) studies are essential for the hotspots (e.g., Jiangxi Province) identified in national-scale studies. However, there are only a few small-scale studies of hotspots and earlier studies have rarely delved into a thorough and detailed analysis of hotspots. In addition, previous studies of fatal geohazards have failed to offer specific geohazard prevention advice, significant for geohazard control policies. To bridge these gaps, this study took advantage of the Jiangxi Inventory of Fatal Geohazards (JIFGH) and employed spatial analysis and the geographical detector to analyze the spatiotemporal characteristics and causes and present prevention advice on fatal geohazards in Jiangxi Province. The study also analyzes the importance of provincial-scale (first-level administrative scale) studies for hotspots identified in national-scale studies. JIFGH includes 386 non-seismically triggered fatal geohazards that caused a total of 979 fatalities in the 1960–2020 period. The temporal trend of fatal geohazards in Jiangxi Province is mainly affected by rainfall and the government geohazard prevention measures. The causes of most fatal geohazards in Jiangxi Province include (i) slope-cutting activities in house construction projects that create steep slopes prone to failure, which threaten the vulnerable residents and buildings nearby and (ii) rainfall that triggers failures of cut slopes. This study not only proposes geohazard prevention advice for Jiangxi Province and tectonically stable areas but also analyzes the significance of provincial-scale studies of hotspots identified in national-scale studies. Therefore, this study contributes to the prevention of fatal geohazards in Jiangxi Province and tectonically stable areas, while also providing an essential reference for other studies of fatal geohazards.

Integrated EDM and 4D BIM-Based Decision Support System for Construction Projects Control

Project schedule monitoring and controlling are critical challenges of construction project management that are not adequately implemented, likely due to the predominance of earned value management and the lack of utilizing technology, such as BIM tools. Unlike earned value, earned duration management (EDM) was developed, which includes several indices to track schedule progress and measure the performance of a schedule. The goal of this research was to establish a decision support system to track and monitor construction project activities during construction, with better performance and accuracy. A survey was conducted and distributed among ten site engineers, selected from different construction sites. The survey asked the site engineers about the possible durations of certain activities; based on their answers, the authors started the proposed system. In this study, we aimed to develop a decision support system (DSS), which combines BIM with EDM to help calculate probabilistic total project duration, visually detecting critical activities, monitoring visually risky activities subjected to delay and visually categorizing the accuracy of estimated duration for delayed activities.

IMPACT OF WORKLOAD AND RESPONSIBILITY LOAD ON WORK STRESS AND JOB PERFORMANCE ON CONSTRUCTION PROJECTS DURING THE PANDEMIC

Construction is one of the sectors that the government relies on to contribute to national growth; the impact of this policy is that the number on the projects is not balanced with construction experts, thereby increasing the workload of construction employees, coupled with the pandemic, limiting construction project activities which are labour-intensive activities that require a lot of interaction and physical activity in the field. This study aims to determine the impact of a workload and responsibility load on work stress and job performance in construction projects during the pandemic. This research uses a correlational descriptive quantitative approach; the population in this study is 100 construction employees in Indonesia. The sampling technique is total sampling with multiple linear regression. The result showed that workload significantly affects the responsibility load on construction project workers in Indonesia. The workload has a positive and significant impact on Indonesian construction project workers. Responsibility load has a positive and significant effect on Workstress on Project Construction workers in Indonesia. The influence of responsibility load on work stress is negative and significant. Work stress on employees does not affect job performance on employees. Namely, there is no effect if construction employees have high work stress on their work. It does not affect job performance. The work stress variable has no positive or significant effect on job performance. Further research can incorporate variables that influence job performance, such as workload, responsibility load, work stress, and others, to improve job performance at construction.

Modeling the influence of multiskilled construction workers in the context of the covid-19 pandemic using an agent-based ap-proach

As the COVID-19 pandemic continues, construction projects have struggled to be completed. As such, it is necessary to find alternatives that optimize the limited human resources that can be working on construction sites. One alternative to do so is using multiskilled workers so workers can be reassigned to construction activities minimizing projects’ disruption due to workers getting contagion with COVID-19. This study simulates the influence of multiskilled workers in the development of a construction project in the context of the COVID-19 pandemic using an agent-based modeling approach. The aim of the study is to quantify the influence of multiskilled workers in the deficit of construction workers due to COVID-19. The proposed model generates six scenarios to include the uncertainty from limited data from the field due to the pandemic context to quantify the deficit of workers to develop a construction project. This study found that using multiskilled workers reduces the deficit of workers required to perform critical activities in construction projects. More specifically, it can reduce the average deficit of workers roughly in half when compared with the alternative of using only single-skilled workers, from 33.4% to 16.7% of deficit. Consequently, multiskilled workers represents an alternative for construction managers to deal with the disruption from COVID-19 in construction projects from a workforce management standpoint. Understanding alternatives to minimize the impacts of COVID-19 in construction projects may assist engineers and managers in applying strategies to develop construction projects accounting the limitations that COVID-19 places on construction sites.

Assessing Site Waste Management Practices and Cost Between Conventional and Industrialised Building System (IBS) Projects in Malaysia

The Urban development and demands in the construction industry and the increasing population numbers have positively contributed to the rising waste generation. The growth and expansion of construction activities enhanced the problem of waste generation on construction sites. In the Malaysian construction industry, there is a pressing issue of minimising construction waste, which causes significant impacts on the environment. Malaysia is moving towards better construction waste management; however, there is still insufficient collection and improper construction waste disposal in projects site. Practices to reduce, reuse, or recycle waste have not yet achieved widespread implementation due to the cost incurred in handling and transporting the physical waste to the dumpsite. Thus, adopting an Industrialised Building System (IBS) has been one alternative to the conventional construction method to reduce construction waste. The research aim is to compare site waste management practices between conventional and IBS projects. The research examines the types of site waste generated from construction project activities, the types of site waste management practices, and the cost involved in managing site waste. The research methodology used qualitative research and used a case study approach. The data is gained from semi- structured interviews with conventional and IBS contractors in Malaysia. The analysis is based on cross-case analysis and pattern matching. Findings from semi-structured interviews based on six comparative case studies revealed that there are some differences between the types of site waste generate by the conventional and IBS projects due to some causes such as improper storage and wrong handling material. Adopting an IBS can greatly minimize construction waste, saving the cost of materials, and improve the environmental performance for overall site conditions. This research shows that the government should play an important role by encourage all the construction company to implement IBS as the new way in minimizing the construction waste.
