Research on 3D Digital Technological Process of Construction Products with Model-Based Definition

To guide the site staff to produce complex construction products with high quality, this paper proposes a three-dimensional digital technological process method for construction products. Firstly, the process information of construction products is processed from the perspective of quality control and quality management. Then, the geometric entities in the product construction process are modeled based on the building information model (BIM). Then, the process information is expressed and integrated into geometric entities by the model-based definition (MBD) technology, and the interactive files guiding product construction are output. Finally, the technological process expression example of the infill wall masonry project shows that the proposed digital technological process method can fully utilize the advantages of three-dimensional space and desktop virtual reality, help to deepen process understanding, improve product construction quality, reduce project cost, and provide new ideas for digital research in the construction industry.

Enabling Co-Innovation for a Successful Digital Transformation in Wind Energy Using a New Digital Ecosystem and a Fault Detection Case Study

In the next decade, further digitalisation of the entire wind energy project lifecycle is expected to be a major driver for reducing project costs and risks. In this paper, a literature review on the challenges related to implementation of digitalisation in the wind energy industry is first carried out, showing that there is a strong need for new solutions that enable co-innovation within and between organisations. Therefore, a new collaboration method based on a digital ecosystem is developed and demonstrated. The method is centred around specific “challenges”, which are defined by “challenge providers” within a topical “space” and made available to participants via a digital platform. The data required in order to solve a particular “challenge” are provided by the “challenge providers” under the confidentiality conditions they specify. The method is demonstrated via a case study, the EDP Wind Turbine Fault Detection Challenge. Six submitted solutions using diverse approaches are evaluated. Two of the solutions perform significantly better than EDP’s existing solution in terms of Total Prediction Costs (saving up to €120,000). The digital ecosystem is found to be a promising solution for enabling co-innovation in wind energy in general, providing a number of tangible benefits for both challenge and solution providers.

Investigating the Impact of Changing the Usage Type of Existing Structure Using BIM

Many real estate owners change the building in terms of the type of usage in response to changes in economic conditions and the requirements of the surrounding environment to get the best potential financial return. To investigate the possibilities of changing the real estate's usage, the owners of these existing structures turned to feasibility study experts for assistance in making the optimum alternatives. So, they need an integrated model between VE and BIM, especially applicable to an existing structure, to determine the optimum usage type for the existing structure. Value Engineering (VE) and Building Information Modeling (BIM) must be connected to profit from both outputs simultaneously. Previous studies only investigated the VE alternatives during the design phase; when they decided to reduce project costs by using construction materials alternatives, they ignored existing structure alternatives significantly when changing the usage type. This study attempts to provide an integrated model between VE and BIM that can be applied to the existing structure to assist in determining the best alternative in terms of the type of usage for such existing structures by conducting BIM methodology such as a feasibility study, including BIM software such as Revit and Primavera. A feasibility study that contains the bank rate of interest. As a result, the maximum financial return is obtained based on predetermined criteria and in compliance with decision-making requirements.

PROJECT MANAGER'S LEADERSHIP STYLES AFFECTING CONSTRUCTION PRODUCTIVITY

Productivity in the construction industry is essential for business sustenance. Project Managers play a significant in achieving productivity in construction. Therefore this study examined the critical project manager's leadership style to influence construction productivity. The study adopted a quantitative research approach; thus, closed-ended questionnaires were distributed to construction professionals via the Survey Monkey platform. Data gathered were analyzed using descriptive statistics to identify frequencies and weighted scores. The findings indicate the main factors affecting construction productivity as incompetent supervising and management, poor leadership, lack of skilled and experienced labour, and poor project communication. Therefore project managers should exhibit supportive (ability to delegate and assign tasks to the employees), charismatic (ability to transform attitudes and beliefs in employees), transformational (ability to inspire others), and democratic (ability to include employees in decision making) leadership styles to influence construction productivity positively. There is an urgent need for project managers to be trained on the appropriate soft skills aspect of managing construction projects to effectively improve construction productivity, reduce project cost and time overruns, and sustain construction businesses.

Augmented reality in design and construction: thematic analysis and conceptual frameworks

PurposeThis study aims to present a comprehensive review, critical analysis and implications of the augmented reality (AR) application and implementation in the construction industry arena and demonstrate the gaps along with the future research agenda.Design/methodology/approachThe construction industry has been under pressure to improve its productivity, quality and sustainability. However, the conventional methods and technologies cannot respond to this industry's ever-growing demands while emerging and innovative technologies such as building information modelling, artificial intelligence (AI), virtual reality (VR) and AR have emerged and can be used to address this gap. AR application has been acknowledged as one of the most impactful technologies in the construction digitalization process. However, a comprehensive understanding of the AR application, its areas of effectiveness and overarching implications in a construction project life cycle remain vague. Therefore, this study uses an integration of systematic literature review and thematic analysis techniques to identify the phases of a construction project life cycle in which AR is the most effective, the current issues and problems of the conventional methods, the augmented parameters, the immediate effects of using AR on each phase and, eventually, the overall influence of AR on the entire project. Nvivo qualitative data analysis software was used to code, categorize and create themes from the collected data. The result of data analysis was used to develop four principal frameworks of the AR applications – design and constructability review session; construction operation; construction assembly; and maintenance and defect inspection and management – and the gap analysis along with the future research agenda.FindingsThe findings of this study indicated that the application of AR can be most effective in the following four stages of a project life cycle: design and constructability review session; construction operation; construction assembly; and site management and maintenance, including site management and defect inspection. The results also showed that the application of AR technology in the construction industry can align and address building industry objectives by various elements such as: reducing project costs through the application of digital technologies, saving time, meeting deadlines and reduction in project delays through integrated, live scheduling and increased safety and quality of the construction work and workers.Research limitations/implicationsOne of the main limitations of this study was the lack of materials and resources on the downfalls and shortcomings of using immersive technologies, AR, in the construction project life cycle. In addition, most of the reviewed papers were focused on the experiments with simulations and in the lab environment, rather than real experiments in real construction sites and projects. This may cause limitations and inaccuracy of the collected and reported data.Practical implicationsThe results of this study indicated that the application of AR technology in construction industry can align and address building industry objectives by various elements such as: reducing project costs through the application of digital technologies; saving time; meeting deadlines and reduction in project delays through integrated, live scheduling; and increased safety and quality of the construction work and workers.Social implicationsApplication of AR in the various stages of a project life cycle can increase the safety and quality of the construction work and workers.Originality/valueThe reviewed literature indicated that substantial research and studies are yet to be done, to demonstrate the full capacity and impact of these emerging technologies in the field. The collected data and literature indicate that amongst the digital technologies, AR is one of the least researched topics in the field. Therefore, this study aims to examine the application of AR in construction projects’ life cycle to identify the stages and practices of a project life cycle where AR and its capabilities can be exploited and to identify the respective problems and issues of the conventional methods and the ways in which AR can address those shortcomings. Furthermore, this study focuses on identifying the overall outcome of AR applications in a construction project in terms of cost and time efficiency, process precision and safety.

A Data-Driven Framework for Probabilistic Estimates in Oil and Gas Project Cost Management: A Benchmark Experiment on Natural Gas Pipeline Projects

Nowadays, the Oil and Gas (O&G) industry faces significant challenges due to the relentless pressure for rationalization of project expenditure and cost reduction, the demand for greener and renewable energy solutions and the recent outbreak of the pandemic and geopolitical crises. Despite these barriers, the O&G industry still remains a key sector in the growth of world economy, requiring huge capital investments on critical megaprojects. On the other hand, the O&G projects, traditionally, experience cost overruns and delays with damaging consequences to both industry stakeholders and policy-makers. Regarding this, there is an urgent necessity for the adoption of innovative project management methods and tools facilitating the timely delivery of projects with high quality standards complying with budgetary restrictions. Certainly, the success of a project is intrinsically associated with the ability of the decision-makers to estimate, in a compelling way, the monetary resources required throughout the project’s life cycle, an activity that involves various sources of uncertainty. In this study, we focus on the critical management task of evaluating project cost performance through the development of a framework aiming at handling the inherent uncertainty of the estimation process based on well-established data-driven concepts, tools and performance metrics. The proposed framework is demonstrated through a benchmark experiment on a publicly available dataset containing information related to the construction cost of natural gas pipeline projects. The findings derived from the benchmark study showed that the applied algorithm and the adoption of a different feature scaling mechanism presented an interaction effect on the distribution of loss functions, when used as point and interval estimators of the actual cost. Regarding the evaluation of point estimators, Support Vector Regression with different feature scaling mechanisms achieved superior performances in terms of both accuracy and bias, whereas both K-Nearest Neighbors and Classification and Regression Trees variants indicated noteworthy prediction capabilities for producing narrow interval estimates that contain the actual cost value. Finally, the evaluation of the agreement between the performance rankings for the set of candidate models, when used as point and interval estimators revealed a moderate agreement (a=0.425).

Evaluating the feasibility of muck from slurry shield tunnels as a growth medium for landscaping

ABSTRACT Muck from slurry shield tunnels (MSST) is a complex mixture. Directly transporting this muck to dumping grounds not only increases the costs but also raises environmental concerns due to its unusual properties. In this study, a formula has been studied that can turn the MSST into an environment friendly soil. The treatment process can realize the harmless disposal and effective utilization of MSST. In the laboratory study, three different types of growing media (MSST, MSST with 1% fly ash, and local garden soil) were used to grow ryegrass in a series of pot experiments, and the seed germination, chlorophyll content, root characteristics, root activity and physical and chemical properties of the growing media were examined. The results showed that MSST and MSSTF (MSST with added fly ash) can be used as a soil matrix for ryegrass because they exhibited a technical performance comparable to that of local garden soil (LGS), and the physicochemical parameters of the soil matrix were enhanced compared with the standard values of CJT 340–2011. Although the additive (fly ash) and different types of substrates can affect plant growth and the properties of harvested soils, the level of variation decreases with the stage of growth. As waste recycling is the primary objective of this work, MSSTF is the ideal substrate to use. The treatment process is easy to handle, and represents a sustainable option and an environmentally friendly, beneficial use of MSST.Implications: Muck discharged from slurry shield tunnel construction has put great pressure on the environment and construction cost because of a large number shield tunnels emerging in cities. Directly transporting the discharged muck waste to dumping site not only increases the machinery and labor costs but also raises environmental concerns. Therefore, we explore the way of recycling the discharged muck from slurry shield tunnel as a growth medium for landscaping which was proved to be feasible by a series of pot experimental study. Recycling the discharged muck from shield tunnel as the growth medium for landscaping instead of using purchased raw materials not only can dramatically reduce project costs but also can obviously minimizing the consequent environment pollution. Such technology can contribute to sustainable developments and cleaner construction of infrastructures.

Mapping of State Transportation Agencies’ Practices and Perceptions in Project Bundling

State transportation agencies (STAs) have been using the project bundling method primarily on bridge projects. While many studies suggest that bundling bridges can reduce project costs and expedite project delivery, more research is needed to help STAs to achieve advanced use of project bundling by understanding the current state of the practice and perceptions about project bundling among STA representatives. This paper presents the detailed findings of a survey, including the perceived benefits, challenges, and risks involved in the bundling method among STA representatives. The survey found that project bundling helps reduce individual project costs in a bundle as well as agency administrative costs and provides an individual project with the flexibility to schedule around other projects in a bundle. Project bundling was found to have a major impact on the cost and delivery time of the project. The major factors that are considered for bundling effectiveness were found to be work type, project type, and spatial proximity. The major concern that most of the STAs had during bundling was that the bundled projects may eliminate the competition from smaller contractors. However, the concerns over the bundling method were found to be less among agencies with a high-level experience of bundling. The survey also found that the majority of STAs have not quantified the impact of the project bundling yet. The results from this study suggest that further research on bundling mixed-type projects and risks associated with bundled contracts is necessary.

Цифровая трансформация как фактор устойчивого развития строительного комплекса

Economic digitalization, along with the transition to a new technological paradigm, has given rise to an ongoing transformation in the Russian Federation, expanding the high-tech industry and driving inno-vation across a wide range of economic sectors. However, the digitization level in the development and construction sectors currently remains one of the lowest among industries, despite the fact that con-struction is involved in creating production capacity and contributes to the growth of fixed assets, which ensures expanded reproduction in the entire economy. Therefore, it is necessary to promote the implementation of digital and innovative technologies in the construction sector, as its digital trans-formation can produce a synergistic effect reducing project costs in general, as well as improving the competitiveness of construction organizations and strengthening their position in the market.

Potential Benefits of Implementing Building Information Modelling (BIM) in the Nigerian Construction Industry

Building Information Modelling (BIM)is an innovative technology that has transformed the way construction projects are delivered. It has helped to overcome the problems of cost and time overruns, poor quality, safety issues, dissatisfaction, and lossof profit, among others; associated with the traditional method of project delivery. Despite the enormous benefits of BIM, its adoption and implementation among construction companiesin the construction industry of developing nations remained low. In order to drive and influence the wider implementation of BIM, this study assessed the perceived potential benefits of BIM in the Nigerian construction industry. The study adopted a survey approach in which well-structured questionnaires were used to gather data from construction professionals in Port Harcourt, Nigeria, using snowball sampling techniques. With 132 responses, the data gathered were analysed using frequencies, percentile, relative importance index (RII) and Kruskal-Wallis test. The study concluded the level of awareness of BIM is high while its adoption is low. Also, the potential benefits of BIM adoption that could encourage wider implementation in construction are; improve project quality, minimize errors and mistakes, better clash detection, reduced construction time, improve multi-party communication and collaboration,improve project documentation, improves efficiency and productivity, project cost reduction, and minimizesdisputes and conflicts. The Government of Nigeria and other African countries should come up with a policy that wouldmake BIM application in construction mandatory.

Assessment of the effect of shapes of a shaft intake structure using the PIV method

The construction of shaft intake structures in Slovakia has increased. The shaft intake structures overcome significant vertical height over short horizontal distance. In their front horizontal section, the water flows with free surface, then in the vertical section the flow changes its direction and character to a pressurized flow. The flow of water in these shaft intake structures is therefore very complicated. A hydraulically suitable design of the intake structure is associated with achieving the required parameters of the small hydropower plant (SHPP), but due to the reduction of project costs, the shapes of shaft intake structures of SHPP are often not correctly hydraulically designed. One of the important aspects is the distribution of flow velocity of these intake structures. Uneven distribution of flow velocity causes negative effects on turbine performance. Therefore, the investigation of the effects of shaft intake structure design on flow velocity distribution has been realized. The velocity field at a shaft intake of a small hydropower plant was investigated on a physical model in a hydraulic laboratory using the PIV (Particle Image Velocimetry) method. The PIV measurements were realized for different shaft heights and proved negative effects of the design on the flow homogeneity in the turbine intake.

JUSTIFICATION OF THE STRESS-STRAIN STATE OF THE PILE FOUNDATION USING SOFTWARE COMPLEXES

Purpose. Bridge supports with a high pile caps require more attention when calculating their strength due to the difficult operating conditions of the piles. The purpose of the scientific article is to substantiate the stress-strain state of the pile foundation of the bridge structure using software computing systems SCAD and LIRA-CAD. Methodology. An analysis of software used to automate the design of foundations was conducted. The main parameters of SCAD and LIRA-CAD software packages are yielded. With their help, finite-element models of the pile foundation of the bridge support with a high pile cap were built. The developed models maximally reflect the properties of the soil base and foundation, its pile cap and piles, geometric characteristics and the influence of the finite elements meshing is considered. Calculations were performed in SCAD and LIRA-CAD software packages with monitoring of the calculation process. Findings. During the numerical analysis of the pile foundation of the bridge structure with a high pile cap, vertical displacements, force factors (normal forces and bending moments) in the piles and stresses in the body of the support and piles were determined. Based on these results, an analysis was performed, which is combined with a comparison of the obtained results. Implementation of SCAD and LIRA-CAD software allows to significantly reduce design time, to reduce project costs, to improve the quality and efficiency of investments. Originality. A comparison of the stress-strain state obtained during the numerical analysis of SCAD and LIRA-CAD software, which proved the difference in the approach to modeling in these complexes, was conducted. Practical value. The results of substantiation of the stress-strain state of the pile foundation with the use of software complexes made it possible to verify the design solution of all elements of the foundation of the bridge structure with a high pile cap.

An Open Drug Discovery Competition: Experimental Validation of Predictive Models in a Series of Novel Antimalarials.

The Open Source Malaria (OSM) consortium is developing compounds that kill the human malaria parasite, Plasmodium falciparum, by targeting PfATP4, an essential ion pump on the parasite surface. The structure of PfATP4 has not been determined. Here, we describe a public competition created to develop a predictive model for the identification of PfATP4 inhibitors, thereby reducing project costs associated with the synthesis of inactive compounds. Competition participants could see all entries as they were submitted. In the final round, featuring private sector entrants specializing in machine learning methods, the best-performing models were used to predict novel inhibitors, of which several were synthesized and evaluated against the parasite. Half possessed biological activity, with one featuring a motif that the human chemists familiar with this series would have dismissed as "ill-advised". Since all data and participant interactions remain in the public domain, this research project "lives" and may be improved by others.

Shell Rounds the Corner on a Whale of a Task

Shell had a problem. It had just spent billions to bring its Appomattox find on line in the deepwater Gulf of Mexico (GOM). That development featured the oil giant’s eighth and largest floating platform in the region. The host semisubmersible weighed 125,000 metric tons—more than the largest aircraft carrier. Shell lauded its ability to reduce project cost by 40%, based on experience gained from the development of its previous four-column production platforms in the US Gulf, including the Olympus tension-leg platform. It would transfer these learnings to its next project—the Vito find in about 4,000 ft of water, 150 miles southeast of New Orleans. The field could hold up to 300 million BOE. At the same time the plans for Vito were being laid out, shale projects leapt to the forefront in the competition for capex dollars, and due to the comparative investment, they were winning. Industry success across the nation’s shale plays helped flood the market with oil, forcing the price per barrel down. Suddenly, spending big money on megaprojects offshore had lost much of its luster. For the US Gulf to reclaim at least some of its competitive advantage, fields could no longer be developed with massive, high-dollar facilities. A management mandate dictated that a new minimal, repeatable solution be found. After several years of study, a favorite emerged. “The original concept of Vito was much larger,” said Kurt Shallenberger, Vito project manager for Shell. “The development was probably similar in size to the Appomattox project that Shell recently completed—a 40,000-ton topsides, and a 50-year field life with a sizable gas-reinjection component to it.” Shell’s method for arriving at the new development scheme was dubbed “Minimal Technical Scoping”—the company would start with the absolute minimum scope and then justify additions upward. The project mantra was “Simpler is safer.” The results were a simplified topsides design as well as streamlined mooring systems for the host facility. “The redesign took it down to what I call the sweet spot of semisubmersibles—around a 10,000-ton deck,” said Shallenberger. “You had seen examples of that with LLOG’s Delta House, Independence Hub, and others like that. That was the sweet spot to where multiple fabricators can build it, multiple yards can integrate it, multiple companies can install it—and you can generally get 100,000 bbl a day through it. Now you’re in a competitive environment for all the vendors rather than just the one guy in the world who can do this. That’s what really created the opportunity for Vito. We shrunk the size and scope down to a point where it could get to a breakeven price that is competitive with the onshore folks.” According to Shell, the breakeven price for their minimal floater design is less than $35/bbl. Shell locked up key vendors for Vito. Jacobs Engineering Group carried out the detailed engineering and front-end engineering design studies for the Vito topsides. Sembcorp would build the host and integrate the topsides and hull at its Tuas Boulevard yard in Singapore.

Evaluation of measures to prevent the spread of COVID-19 on the construction sites.

COVID-19 is the most critical health and safety risk facing the global construction sector. The COVID-19 crisis leads to a reduction in site productivity, has increased compliance costs, delayed projects and increased construction workers' exposure to risk and infections. However, as countries begin to ease lockdowns and restrictions, there is a need to examine the measures that the construction companies can take to ensure workers are “Covid-safe”. This research developed a questionnaire instrument that included 24 Covid-preventive measures on construction sites. Isolating sick workers, conducting daily checks for COVID-19 symptoms, preventing hugging/handshaking at the site, displaying health advisory posters and info-graphics, and providing face masks to workers are seen to be the main measures towards keeping sites “Covid-safe”. The Principal Component Analysis structured the 24 measures into 4 components. The 4 components explained about 73% of the model, namely hygiene and control, equipment and monitoring, awareness, and incentives. The results found that compliance costs of health and safety regulations to prevent COVID-19 will increase project cost by more than 20%, site productivity will be reduced by up to 50%, and the pandemic will have caused a 40% increase in skill shortages. Cluster analysis was performed to cluster the sites in terms of their exposure to COVID-19 risk. In order to examine the practicability of the findings, the model was validated with 4 case studies. It is asserted that the research findings have the potential to keep sites “Covid-safe”, which helps construction companies increase productivity, reduce project costs, reduce claims, and deliver projects on schedule. This research is the first to examine measures to prevent the spread of COVID-19 on construction sites, and the findings hold critical theoretical and practical implications for future research on health and safety management.

Cost Control and Project Cost Analysis of Intelligent Building under Internet of Things

The conventional urban system has a very disorganized and unmanageable mode of operation, and the information between the systems has not been efficiently shared and interconnected. Smart cities and intelligent building will be the future trend of urban development. With the advent of new concepts and techniques brought by the Internet of Things (IoT) across the world, all fields of life are progressively shifting towards smart societies. Based on the prediction algorithm of the IoT, this paper constructs the cost control and cost prediction model of intelligent building. Combined with the characteristics of the current smart city construction, three engineering cost schemes (S0, S1, and S2) are constructed, and the cost simulation of these three examples is carried out to verify the cost control and cost prediction model of the intelligent building. Experimental results show that the total cost of each cost level of the three schemes is lower than the conventional total cost, and the total cost change rate ranges are −121.6%∼−27.6%, −210.3%∼−47.2%, and −150.3%∼−22.3%, respectively. The proposed smart city cost prediction model can reduce project cost, which has great economic significance for the construction of smart cities.

Contract bundling considerations in urban road project scheduling

AbstractRoad project scheduling and contract bundling are two separate concepts that profoundly influence project delivery consequences to key stakeholders. Therefore, agencies espouse initiatives for contract bundling (to reduce project costs) and project scheduling (to reduce user delay costs). Bundling combined with scheduling could potentially yield benefits to both the agency and urban road users. This paper investigates the overall benefits (to the two stakeholders) of optimal schedules with bundling considerations, compared to the optimal schedules for unbundled contracts. The agency's objective is to make scheduling‐with‐bundling decisions that minimize system‐wide travel time and project costs, and the users’ objective is to minimize their travel times in the network with work zones. The problem is solved using the non‐dominated sorting genetic algorithm. The numerical experiments suggest that with well‐designed bundling, optimal scheduling can significantly reduce not only the project cost but also the total system cost (project and travel delay).

Application research on the design of assembled shear wall joint based on BIM technology

In response to the strategic slogan of sustainable development, China has intensified efforts to develop prefabricated buildings, so the node design of prefabricated buildings becomes particularly important. In this paper, a prefabricated residential building project in Shenyang is taken as an example. BIM technology is introduced into the design of prefabricated shear wall joints based on BIM visualization and parameterization features. The main purpose is to optimize the design of partial T-type and L-type shear wall joints, and to conduct optimization analysis through collision detection. The application of BIM technology can greatly improve the efficiency of shear wall joint design, promote the standardization of prefabricated shear wall joint design, further promote the modular design and production of prefabricated components, reduce project cost, ensure project quality, and give full play to the value of BIM technology in prefabricated construction projects.
