Critical factors affecting Chinese construction expatriates’ living and working conditions in Thailand: a Delphi study

Expatriation management is a key concern in international construction projects, where the living and working conditions of expatriates can have a significant impact on project success. This study investigates the critical factors affecting Chinese construction expatriates’ living and working conditions in Thailand. Through a three-round Delphi technique involving twelve experts and in-depth semi-structured interviews with eight construction experts with extensive overseas experience to validate, six critical factors were identified for each living and working condition. Language and Covid-19-related (during the investigating period) factors were the most dominant factors affecting the living conditions, while technical standards, technology, and competition were critical factors for working conditions. The study categorizes the critical factors into five groups and provides suggestions for improvement. This research is the first to investigate the specific factors affecting Chinese construction expatriates in Thailand and offers insights and management directions for the expatriation process, particularly for the growing number of Chinese construction companies expanding internationally. The findings also serve as a valuable reference for future research on this topic.

Modelling the relationship between digital twins implementation barriers and sustainability pillars: Insights from building and construction sector

A Digital Twin (DT) is a digital copy of a real-world object or process. Although DT has gained traction in construction, its relationship with sustainable success remains insufficiently studied. This research addresses this gap by investigating barriers to implementing DT in sustainable construction. The study employs a hybrid approach involving literature review, expert interviews, and modeling techniques, with data collected from 108 construction experts based on a number of criteria, including the experience, degree, and familiarity of the experts about the Hong Kong building and construction sector Hong Kong. The findings reveal 45 barriers categorized into six clusters, including notable obstacles such as "legacy systems," "data uncertainties," and "connectivity." The key clusters identified are "performance" and "security," while the "social" aspect of sustainable success is least supported. Recognizing these challenges assists decision-makers in navigating obstacles and utilizing DT for environmentally conscious construction, streamlined processes, and positive societal impacts. Future research could delve into integrating sustainability throughout the project lifecycle using technology adoption theories.

Measures To Mitigate The Main Causes Of Social Hoising Delays In Algeria

Social housing in Algeria is carried out with state budget funds in order to eliminate social inequalities and guarantee a decent life to the citizen. However, delays have been observed in the realization. This study aims to examine the main causes and develop guidelines to effectively mitigate delays. Through an in-depth analysis of the literature and formal interviews on the topic of potential risks with construction experts, a list of 67 delay factors was identified. Data was collected through an online questionnaire via Google Forms and semi-structured interviews of a sample professionals established in Algeria. A total of 59 valid responses were analyzed and classified by SPSS software. The results indicate that the 5 most critical causes are: "Delay in payment", "Slow change orders in extra works", "Ineffective planning and scheduling", "Slow change orders in extra quantities", and "Difficulties in financing the project by contractor". Though, the correct implementation of the measures suggested by this study allows government authorities and professionals to deal with the 10 most critical causes that have favored the occurrence of delays in order to successfully implement similar construction projects.

Assessment of Seismic Vulnerability of School Buildings: A case study in Bandung, West Java, Indonesia

Indonesia is an earthquake-prone country. In many earthquakes, school buildings suffer the most damage than other public facilities. In 2020, the conditions of around 70% of 218,234 school classrooms in Indonesia were deteriorating. This contributed to a significant earthquake vulnerability. Limited funding for rehabilitation and renovation became an obstacle to reduce the vulnerability. This study proposed that Rapid Visual Screening (RVS), which is a simple method and has a wide coverage, could be a solution to prioritize building rehabilitation. Bandung, the capital city of the most populated province in Indonesia, has complex earthquake hazard risks, which made it a suitable study area for implementing RVS. This study conducted a seismic vulnerability assessment of school buildings in the city of Bandung, Indonesia. The methodology used is based on Indonesia National Disaster Management Agency (BNPB)’s Regulation No. 4 of 2012 on Rapid Visual Screening (RVS) procedure compared to FEMA 154 RVS procedure with local hazard data and building data. RVS was conducted in total 334 elementary school buildings in 30 districts. The result of the BNPB’s RVS procedure showed an average RVS score (S) of 4.455 where 36.53% buildings were in safe condition and 63.47% buildings required further assessment of the conditions from construction experts. The result of the FEMA 154 RVS procedure showed an average RVS score (S) of 0.905 where 22.16% of the buildings were in high probability of grade 4 damage and 77.84% of the buildings were in high probability of grade 3 damage.

Dispute Classification in Construction Projects Based on Litigation Cases

Disputes in construction projects arise due to failure to address their root causes and lack of procedures for dispute avoidance and mitigation. Courts are facing a growing number of construction-related lawsuits that hinder the resolution processes with negative impact on the project completion. This study was an attempt to define major causes of disputes in construction projects from a review of 177 selected litigation cases in the Kuwaiti courts. Dispute sources in construction were classified into four categories: abnormal conditions, financial situation, project delay, and project management. Statistical analysis was conducted to rank the severity of dispute sources. For verification of results, construction experts were interviewed. A regression model was used to predict the disputed claim value. The most severe dispute sources were ranked according to the following: payment delay, contract documents (incomplete information, conflict of interest in both parties, noncompliance, unawareness), main contractor time delay, and owner time delay. It is hoped that results open avenues to a clearer understanding of the causes of disputes in contractual agreements in the construction industry, as well as identify areas to mitigate dispute occurrences. Because the scope of the research was limited to Kuwait, findings of this investigation may lead to a more in-depth investigation of other court scenarios of similar nature from the other parts of the Gulf region.

IMPACT FACTORS ON TIME AND COST IN PILE CONSTRUCTION

Construction activities have increased due to Saudi Arabia's Vision 2030 programs, accelerating change across all sectors. However, the pile construction sector has already experienced significant time and expense overruns that have had a negative impact on all parties. This study aims to identify and investigate the significant risk influencing the timing and cost of pile construction projects in Saudi Arabia. The most risks were gathered and found in the literature. Two questionnaire-based surveys were undertaken to establish the perspectives of the construction experts on the degree of probability of occurrence of each risk. To collect the qualitative and quantitative experts’ responses, the data questionnaire was analyzed using the Artificial Neural Network (ANN) model to identify the significant risks in terms of cost and time of pile construction. The main finding showed that the significant risks are DR1 (improper and insufficient assessment of soil), CR1 (labor mistakes, rework, and idle times), OGR5 (Delay or inability of the owner to provide full possession of site), ECR1 (lack of funds: the lack of cash flow by the contractor), ECR6 (foreign exchange risks: unstable exchange rates, transfer restrictions, and supply and demand balance), ECR5 (economic crisis), PGR1 (failure to obtain approvals or permits), CR3 (low credibility), SCR1 (lack of management skills). This study assists the decision makers in a deeper understanding of the influencing factors, allowing them to make effective scheduling and comprehensive control over pile foundation projects.

Priorities in Croatian School Building Maintenance: A Comparison of the Main Stakeholders’ Views

This paper aims to examine the opinions of the main recognized stakeholders in the maintenance of school buildings (i.e., the construction experts within the founders’ organization, the school staff, and the students), compare their views on the maintenance priorities, and identify certain differences. These data provide information about user needs, can help school founders make maintenance decisions, and are the basis for developing a new, balanced system of maintenance priorities. In the research, the survey questionnaire method was used to collect the data, whereby three groups of stakeholders evaluated the priority of eliminating certain defects in school buildings on a 5-point scale. For the purposes of the questionnaire, a model of 32 defects of the school buildings was created. In the questionnaire, 76 experts, 338 school staff, and 297 students participated. The research is limited to the Republic of Croatia. By conducting non-parametric statistical tests (Kruskal–Wallis and Mann–Whitney), it was shown that there were statistically significant differences in the stakeholders’ attitudes towards most maintenance priorities. There were also defects where statistically significant differences were not recognized, namely, regarding faulty lighting fixtures, faulty toilets, faulty sinks, faulty space cooling systems, faulty space heating systems, and faulty hot water heating systems. According to the experts, it is most urgent to remove faulty electrical installations, while according to the school staff, the highest priority is faulty sewage installations. The students believe that the priority is faulty toilets. The lowest priority is removing damage to the external environment (experts) and the facade (school staff and students).

Investigation of barriers and mitigation strategies to blockchain technology implementation in construction industry: an interpretive structural modeling approach.

Blockchain technology has emerged as a promising solution for enhancing transparency, efficiency, and security in various industries, including construction. However, implementing blockchain in the construction industry faces several barriers that hinder its widespread adoption. To fill this gap, this study is aimed at identifying and discussing the key barriers to implementing blockchain in the construction industry. The study employs a four-phase methodology. In the first phase, barriers are identified through a comprehensive literature review and supplemented with semi-structured interviews with different stakeholders, identifying critical barriers. The second phase involves data collection from ten construction experts, while the third phase utilizes the interpretive structural modeling (ISM) technique for data analysis. In the fourth phase, ten effective strategies are formulated to tackle the identified barriers and their interdependencies. The results reveal the overall structure of barriers and classify them into four groups based on driving and dependence power using the cross-impact matrix multiplication applied to the classification (MICMAC) technique. The identified barriers include a lack of collaboration in consortium formation, insufficient capacity and performance, and regulatory uncertainty, which hinders blockchain implementation in the construction industry. The research findings provide valuable information for policymakers on the overall structure with barriers and implementation in India and other countries with similar situations. Additionally, the management implications of the results were analyzed to facilitate the effective implementation of measures to overcome the obstacles and increase the level of blockchain adoption in the construction industry.

Интеллектуализация строительно-технической экспертизы кровель как инструмент управления ее жизненным циклом

The program "Digital Economy of the Russian Federation", approved by the Government of the Russian Federation, is being actively implemented in the building construction industry, mainly at the stages of engineering surveys and architectural and construction design. Building information modeling (BIM) technologies are used by most foreign and domestic CAD system vendors. At the other stages of the building's life cycle, digitalization has not been widely distributed, despite the fact that the operation stage is the longest and the trouble-free existence of building structures at this stage is the key to the economic and social efficiency of building ownership. Flat rolled roofs in our country are the most common type of roofs and at the same time the most susceptible to defect formation structural element of a building. The standard operation period of such roofs is 10 years, despite the fact that the actual period of trouble-free operation of flat rolled roofs rarely exceeds 7 years. The assessment of the technical condition of the roofs is carried out by a construction and technical expertise, performed, as a rule, after the occurrence of leaks. Assessment of the degree of damage, as well as the prevalence of defects, is carried out by an expert visually, often without the use of measuring equipment. Due to the fact that the assessment of damage by an expert is purely subjective, it is impossible to correctly assess the development of the defect over time. The proposed technology of automation of construction and technical expertise of flat rolled roofs of a building allows timely detection of defects, assess the degree of their danger and make forecasts of their development over time. This approach allows you to make a timely decision on the need to carry out current repairs or to plan their implementation in the future. This will increase the service life of a flat rolled roof without increasing the cost of the life cycle.

Critical success factors for construction industry transition to circular economy: developing countries’ perspectives

PurposeCircular economy (CE) is increasingly used as a system solution framework for tackling climate change. Existing CE solutions have been found effective in other sectors but ineffective in the construction sector (CS) due to the inability to account for unique CS dynamics that are essential for its success. With CS being one of the worst polluters, this research aimed to investigate critical success factors (CSFs) and a practical CE implementation framework for the sector.Design/methodology/approachMixed methods research involving descriptive surveys of construction professionals in Kazakhstan, Malaysia and Turkey was used to explore priority dimensions of McKinsey’s ReSOLVE (“regenerate, share, optimize, loop, virtualize and exchange”) circulatory framework, and the associated CSFs that underpin successful implementation of CE in the sector. Empirical data were analyzed using the fuzzy analytical hierarchy process (F-AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) algorithm.FindingsResults showed that “Optimize” and “Loop” were the most critical of the six dimensions of CE implementation framework for successful circularity transition of the CS in each case study country. Twenty-seven CSFs identified in the study were clustered into seven key action areas for successful rollout of the ReSOLVE framework, namely, legislative and documentation, financial, design, external/stakeholder, technological, internal and construction/production/waste management.Practical implicationsThe study makes a unique contribution to existing knowledge by exploring ReSOLVE-based CSFs for successful CE implementation in the CS through the lenses of experienced construction practitioners and experts in developing countries. The findings are expected to provide a deeper insight into the most significant CSFs to be focused on with the limited resources available to decision-makers in the CS. The findings would also inform regulatory policy reformations aimed at facilitating greater rate of implementation of CE in the construction value chain.Originality/valueThe study – the first of its kind – established and validated a wholistic and construction-specific CE implementation framework to guide built environment professionals and policymakers in formulating a roadmap for successful CS’s transition to circularity and hopefully paving the way for improved economic, social and environmental performance of the sector.

Modeling the Effect of Overcoming the Barriers to Passive Design Implementation on Project Sustainability Building Success: A Structural Equation Modeling Perspective

To maximize profits without sacrificing quality, the concept of sustainable construction must be adopted across a project’s whole lifespan. Although adopting the idea of passive design in developing countries is incomplete, these studies have focused on the reasons for doing so. In contrast, there is limited evidence to completely analyze the influence of integrating passive design on the project sustainable success (PSS) of projects throughout their existence. This study focuses on the hurdles to passive design adoption in Pakistani building projects. It evaluates the impact of overcoming passive design (PD) adoption barriers on project sustainability success (PSS) during the duration of the project. Therefore, a more comprehensive literature assessment is required for conceptual model construction. Using a survey assessment instrument, Structural Equation Modeling (SEM) was constructed (i.e., a questionnaire). A total of 156 construction experts in Pakistan provided information. The result of the model demonstrated that the elimination of PD implementation obstacles had a moderate to high impact on PSS throughout the building structure’s lifetime. These results provide the foundation for legislation in a number of Asian nations about the efficient completion of projects via the removal of obstacles for the use of passive design. Similarly, the adoption of passive design will increase the success of the construction project.

A virtual reality-based constructability index for construction projects

Purpose This study aims to develop a constructability index (CI) that can ease the construction activities in a project based on the contractors’ experience and resources. The proposed CI is a vital decision support tool that quantifies the difficulty level for the contractor to execute certain activities with the contingency of other project elements. The virtual reality (VR) technology was used to provide additional data, communicate the contingency impact of other project elements on specific activities and provide sequential execution data to the contractors. This can minimize the risk of not being able to execute various activities on time and within the budget. Design/methodology/approach The VR-based CI was developed through two steps. Step 1 was to identify the factors affecting constructability by exploring the literature and consulting local construction experts. These factors were then organized through a hierarchy of main factors and subfactors and validated by local experts through predesigned surveys. The factors were classified into VR dependent or non-VR independent, and their relative weights were calculated using the analytical hierarchy process along with their reliability, which was determined using Cronbach’s alpha approach. Step 2 was to define the attributes for the constructability factors defined in Step 1 using the Multi Attribute Utility Theory to quantify the contractor’s compliance level of these factors by giving them the appropriate score. The utility factors for the VR-independent factors were obtained through standards, literature and local surveys, and they were quantified on a 1–10 scale. However, the VR-dependent factors were given their corresponding scores using the developed VR navigation environment generated by integrating Autodesk Revit and Navisworks software. Accordingly, the CI for each activity was evaluated, and the overall CI for the project was calculated by aggregating the CIs for all activities. Findings The developed CI quantifies the contractor’s ability to execute construction projects and addresses the lack of communication and coordination between the various construction units in the planning phase itself. Moreover, it can resolve possible hard (physical) and soft (time) construction clashes and minimize their impacts on project schedule and budget. Among the relative weights of the identified factors, prefabrication of building components was found to have the highest effect on constructability. Furthermore, applying the developed VR-CI, a real project showed that the utility values of the main factors quantified on a ten-point scale were between 6 and 9, which means routine supervisions and monitoring are required. Originality/value Though the concepts of constructability and VR have been used in different contexts, their integration to develop a comprehensive CI for the building construction industry is a unique contribution, which has not been reported previously.

Integrated Methods for Selecting Construction Foundation Type Based on Using a Value Engineering Principle

The cost of constructing foundations, on average, ranges from 10% to 15% of a project’s total cost. Therefore, selecting the appropriate type of foundation may result in a significant reduction in project costs. In this study, a value engineering (VE) approach was applied to select the best foundation type from seven alternatives that covered shallow and deep foundations. Selection was dependent on ten important criteria, which were classified into safety, buildability, flexibility of architectural design, and environmental impact. Foundation construction experts used the stepwise weight assessment ratio analysis (SWARA) method to determine the weights of these ten properties for six identified cases based on structure type and soil type. In addition, the weighted aggregated sum product assessment (WASPAS) method was used to determine the quality weight for each foundation option. The results show that adaptable architectural design requirements were more critical in selecting the foundation than the safety criteria for a bridge project. Additionally, the criteria for environmental impacts in the case of high-rise buildings have a more significant impact on foundation choice than low-rise buildings. The outcomes of this study may improve the adaptability of architectural design and the environmental impact of future structures and building codes in the construction industry.

Exploring Perceptions of the Adoption of Prefabricated Construction Technology in Pakistan Using the Technology Acceptance Model

Prefabricated construction is being pursued globally as a critically important sustainable construction technology. Prefabricated construction technology (PCT) provides opportunities to effectively manage construction waste and offers venues to address the poor productivity and lackluster performance of construction projects, which are often expected to miss their budget and schedule constraints. Despite the significant benefits inherent in the adoption of PCT, research has shown an unimpressive exploitation of this technology in the building sector. A modified version of the popular technology acceptance model (TAM) was used to understand Pakistan’s building construction industry stakeholder’s acceptance of PCT and the factors that influence its usage. Data were collected from 250 building construction experts in the industry to test the hypotheses derived from the proposed model. Data analysis using covariance-based structural equation modeling revealed that construction industry stakeholders’ perceptions of perceived ease-of-use, perceived usefulness, trust, and satisfaction all strongly influenced PCT acceptance behavior. Moreover, results also confirmed the total direct and indirect effects of the perceived usefulness and perceived ease-of-use of behavioral intention toward using PCT, with trust and user satisfaction as mediators. The results of this research are expected to serve as a guide for the construction industry stakeholders to effectively plan, strategize, encourage, and increase the adoption of PCT to achieve sustainable construction outcomes in the building construction sector.

Expertise in Complex-Well Construction Leveraged for Geothermal Wells

_ This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 204097, “Constructing Deep Closed-Loop Geothermal Wells for Globally Scalable Energy Production by Leveraging Oil and Gas Extended-Reach Drilling and High-Pressure/High-Temperature Well-Construction Expertise,” by Eric van Oort, SPE, Dongmei Chen, SPE, and Pradeepkumar Ashok, SPE, The University of Texas at Austin, et al. The paper has not been peer reviewed. _ In the complete paper, deep closed-loop geothermal systems (DCLGS) are introduced as an alternative to traditional enhanced geothermal systems (EGS) for green energy production that is globally scalable and dispatchable. The authors demonstrate that DCLGS wells can generate power on a scale comparable to that of EGS. They also highlight technology gaps and needs that still exist for economically drilling DCLGS wells, writing that it is possible to extend oil and gas technology, expertise, and experience in extended-reach drilling (ERD) and high-pressure/high-temperature (HP/HT) drilling to construct complex DCLGS wells. Introduction CLGS is considered a subset of EGS, but the authors write that it is a distinct entity. EGS mostly involves well designs that rely on fractures for heat extraction. Such systems are different from CLGS wells in that the latter use closed conduits for thermal fluid circulation and heating. CLGS relies on fluids pumped through a closed loop. The authors treat CLGS systems as being different from EGS systems, with the understanding that drilling technologies discussed in the paper as enablers for CLGS wells apply equally to EGS wells. In the geothermal (GT) domain, the majority of attention and funding currently is assigned to EGS projects. A case is made in the complete paper to continue to develop DCLGS technology because of its favorable risk profile compared with EGS. Part I of the complete paper introduces a hydraulic model coupled with a thermal model suitable for calculating the power generation of DCLGS wells. This synopsis concentrates instead on Part II of the complete paper, in which technology gaps and needs of DCLGS drilling and well construction are highlighted and opportunities identified where oil and gas experience and technology can be directly applied and leveraged. Similarities and Differences of Deep GT and Oil and Gas HP/HT Wells - GT wells generally use larger production hole sizes than typical land wells. - Casing-cement annuli typically are cemented back to surface. - GT wells can be drilled in more-forgiving pore-pressure fracture gradient (PPFG) environments with wider drilling margins than geopressured HP/HT wells in hydrocarbon systems. - Severe lost circulation appears to be a universal problem in deep GT wells. - Drilling costs can account for 50% or more of the total capital costs for a GT energy project. - Data sets on GT wells are much smaller than those for oil and gas wells.
