Abstract: Accidents and injuries continue to be major problems in the construction industry despite persistent endeavours over the years to improve health and safety management. Novel approaches using emerging technologies can enhance construction safety performance. Given their limited adoption and lack of empirical evidence in the context of developing countries, this paper examines the predictors influencing the successful adoption of safety technologies in the construction industry. Using a survey questionnaire involving 133 Malaysian construction professionals, the significance of the predictors is prioritised. A factor analysis is used to reduce the predictors involved into a fewer number of dimensions. The most influential predictors are presented. Four underlying dimensions of the surveyed predictors are uncovered, comprising organisational commitment/technology orientation, supporting technological attributes, personal perception erformance expectancy and government support. The rate of technology implementation to improve safety risk mitigation in construction is still limited. By taking cognisance of the critical influential predictors involved, the adoption level of safety technology could be raised. This paper bridges the identified knowledge gap regarding the dimensionality of safety technology adoption predictors in construction, with findings that shed new light on the factors influencing technology adoption in a developing country to stimulate technological innovations to streamline construction safety.

Abstract: Electronic purchasing or e-procurement saves millions of dollars yearly in transaction costs. E-procurement helps to cut down the supplier base, promotes paperless transactions, and increases transparency and accountability in the procurement process. Nonetheless, studies report that around 80% of e-procurement initiatives have met with failure and failed to achieve the desired results. Although studies to better understand the Critical Success Factors (CSFs) of e-procurement implementation involving various industries have been on the rise, little is known about architecture engineering and construction (AEC) practices, which has led to limited development of pragmatic frameworks to uncover the factors. Thus, this study aims to identify those CSFs (predicting variables) which significantly contribute to e-procurement implementation success in the construction sector and to put forward for better implementation. Results from multiple regression analysis revealed five factors to be statistically significant predictors of success. Three factors were determined to be predictors of user satisfaction. Finally, internet online procurement frameworks were developed for the success of e-procurement implementation in the construction sector.

Abstract: Frequent changes pervasively undermine project schedule performance. Despite voluminous research into project delays, however, the persistence of the problem demands that a systemic approach be adopted to investigate design change causation and to explore the efficacy of communications and knowledge as strategic project controls. Drawing on a hybrid research design, the critical variables are identified and mapped onto causal loop diagrams to enable practical holism. The findings indicate that effective project communications engenders collaborative team dynamics and collective learning, whereas project learning contributes to knowledge reuse and the improved expert judgment needed for transforming design change management and schedule control.

Abstract: There were increasing concerns on the possibility and suitability of using elevators for high-rise building evacuation because, through the improvement of the elevator system, the self-evacuation ability of age people is promoted as much as possible in the process of an emergency evacuation. The combined evacuation using both elevators and stairs was put into discussion. However, there was no empirical evidence and numerical simulation on emergency evacuation using both elevators and staircases for aging people in high-rise nursing homes. Therefore, using one case study, this paper simulated the emergency evacuation in a high-rise nursing home using variables such as the distribution of the elderly with different physical conditions, the proportion of the elderly in different physical conditions, the number of the elderly, the number of floors, the number of elevators used, and the priority of the elevator floor. By simulating the evacuation process in various scenarios, the general distribution strategy of high-rise nursing home and the optimal use of the elevator-stair combination during the emergency evacuation were developed. Results show that the elevator-stair combination of evacuation is more effective than using elevators or stairs alone. Increasing the number and speed of elevators can reduce evacuation time. Categorizing elderly people on each floor according to their physical conditions could reduce the evacuation time than randomly distributing them.

Abstract: Legions of projects fail to attain their time and cost objectives due to ineffective coordination. This is often due to a lack of essential learning from projects because of insufficient communication and working experience. One of the key reasons why this occurs is that managers are unaware of what knowledge needs to be retained. In contrast with knowledge management research, which mostly focuses on the systems and processes for capturing, storing, and retrieval of knowledge, this paper investigates the nature of project communication and learning and their role on project time and cost control. A stratified proportional purposive s ling approach was adopted in choosing the interview participants for the study. They are experienced industry practitioners working on building construction projects in Malaysia. Content analysis was then performed on the interview data. The identified variables were further validated by 11 industry experts from the three primary construction stakeholders. The results of a series of 12 in-depth interviews with industry practitioners are provided to reveal the effective communication tools for sharing and learning in a project-based environment, the learning inducing situations involved, and the use of reusable project experiences to improve project time and cost control. A possible limitation of the study is its focus on a small group of Malaysian practitioners delimits the generalizability of the findings. A two-phase model with three-step project management process of input, tools, and output is developed from the Project Management Body of Knowledge (PMBOK) Guide as an aid for more effective knowledge reuse in project time and cost control in the future.

Abstract: Quantity surveying is a profession that blends engineering, construction and economics. To be competent is to have the ability to apply the set of related knowledge, skills and abilities to perform a task effectively. This paper examines the competency requirements for quantity surveyors (QSs) in the face of changing and increasing client needs. Based on a detailed meta-analysis of the literature, 12 basic/core and 16 evolving competencies are identified. Primary data were gathered through a field survey involving practicing QSs from client, consultant and contractor organisations, and university students undertaking QS programmes in Malaysia. The data obtained were analysed using both descriptive and inferential statistical tools. The significance of the basic/core and evolving competencies are presented. Overall, the most important contemporary skills are cost planning, valuation of works, measurement/quantification and contract documentation. The evolved roles require expertise in communication and negotiation, ethics and professional conduct and value management. The analysis of variance (ANOVA) indicates there are misaligned expectations of the proficiency levels needed to provide contemporary and future services between practitioners in client/consultant organisations, contractors and new generation students. The findings provide guidance on the education, training and practice of quantity surveying to deal with emerging challenges in the dynamic built environments in Malaysia and beyond.

Abstract: The adoption rate of new technologies is still relatively low in the construction industry, particularly for mitigating occupational safety and health (OSH) risks, which is traditionally a largely labor-intensive activity in developing countries, occupying ill-afforded non-productive management resources. However, understanding why this is the case is a relatively unresearched area in developing countries such as Malaysia. In aiming to help redress this situation, this study explored the major barriers involved, firstly by a detailed literature review to identify the main barriers h ering the adoption of new technologies for safety science and management in construction. Then, a questionnaire survey of Malaysian construction practitioners was used to prioritize these barriers. A factor analysis further identified six major dimensions underlying the barriers, relating to the lack of OSH regulations and legislation, technological limitations, lack of genuine organizational commitment, prohibitive costs, poor safety culture within the construction industry, and privacy and data security concerns. Taken together, the findings provide a valuable reference to assist industry practitioners and researchers regarding the critical barriers to the adoption of new technologies for construction safety management in Malaysia and other similar developing countries, and bridge the identified knowledge gap concerning the dimensionality of the barriers.

Abstract: Previous studies demonstrate that rework can lead to more safety incidents. However, there is an inadequate understanding of how construction rework reduction measures may significantly decrease the likelihood of safety incidents in developing countries. To explore how construction organisations can integrate rework minimisation and safety management in practice, this study examines the effectiveness of the management strategies that can reduce rework and improve safety. Based on a two-stage detailed literature review of both rework- and safety-related studies, 13 managerial measures are recognised that are capable of jointly reducing rework and safety incidents for construction projects. A field survey involving construction professionals in Malaysia was used to analyse and rank these measures according to effectiveness indices for rework, safety and joint rework-safety management. Factor analysis yielded a two-factor solution comprising (1) project management best practices and (2) proactive competency management. It is suggested that the construction industry would benefit from simultaneously ameliorating the quality and safety performance of projects by adopting effective joint measures that are predominantly guided by process (best practices) and people (competency management) components.

Abstract: Teamwork in the construction industry has attracted much attention from both academic and industrial circles. Most importantly, improving team effectiveness will increase the likelihood of successful project delivery. Recognising the factors influencing team dynamics is important for enhanced team performance. Based on a detailed literature review, a survey questionnaire containing 10 aspects and 25 attributes of teamwork relevant to construction is used to collect feedback from Malaysian construction practitioners from client, consultant and contractor organisations to prioritise these hypothesised variables. The data are then subjected to reliability analysis, descriptive statistics (means, standard deviations, and frequencies), a one-s le t -test, the Kruskal–Wallis ANOVA and exploratory factor analysis. The significance of these aspects and attributes is then presented. The three most crucial aspects are “project performance”, “decision-making capability” and “problem-solving ability”. The most influential attributes are “effective communication between project team members”, “efficient team leadership”, “well-defined team responsibilities and roles”, “clear team goals and objectives” and “good collaboration between all project leaders”. The Kruskal–Wallis ANOVA reveals five attributes having statistically significant differences with respect to company size, namely “clear team goals and objectives”, “commitment to the project”, “adequate resources”, “team or task processes” and “creativity and innovation”. Six underlying dimensions are found, comprising (1) participative engagement and task commitment (2) team responsibility structure and accountability (3) culture of trust and respect (4) leader's skills and abilities (5) top management support and (6) synergic working environment. The identification of these dimensions for team effectiveness provides rigorous basis for formulating useful team-building strategies for integrating a collaborative environment among project stakeholders and consequently improving project performance. This paper bridges the identified knowledge gap concerning the dimensionality of teamwork attributes in construction-based setting and adds to existing knowledge of how team effectiveness can be leveraged to improve project performance in the construction management literature.

Abstract: The production of sleeve grouting in prefabricated construction is routinely plagued by a variety of factors, and lack of mass data and complex environmental conditions over time make problems inevitable. Thus, a dynamic risk control system is a valuable support for the successful completion of the sleeve grouting process. This study aims to develop an entropy-based sleeve grouting risk dynamic control system. First, static risk assessment was conducted through the structured interview survey using the entropy weight method, followed by a dynamic risk control technique, where indicators were simulated through system dynamics containing causal loop diagrams and stock-and-flow diagrams. Finally, three types of risk control models, namely, “tortuous type”, “stable type” and “peak loop type”, were developed in the entropy-based sleeve grouting risk dynamic control system and simulated using system dynamics in a real case. Compared to traditional sleeve grouting risk management, the developed system enabled dynamic control over time.

Abstract: Corruption continues to be a pervasive stain on the construction industry in developing countries worldwide, jeopardising project performance and with wide-ranging negative implications for all facets of society. As such, this study aims to identify and analyse the causes of corruption in the construction sector of an emerging economy such as Malaysia, as it is crucial to uncover the specific facilitating factors involved to devise effective counter strategies. Following a detailed literature review, 18 causes of corruption are identified. The results of an opinion survey within the Malaysian construction industry are further reported to rank and analyse the causes. The factor analysis technique is then applied to uncover the principal factors involved. The results indicate that all the considered causes are perceived to be significant, with the most critical causes being avarice, relationships between parties, lack of ethical standards, an intense competitive nature and the involvement of a large amount of money. A factor analysis reveals four major causal dimensions of these causes, comprising the unique nature of the construction industry and the extensive competition involved unscrupulous leadership, culture and corruption perception a flawed legal system and lack of accountability and ineffective enforcement and an inefficient official bureaucracy. The study presents the Malaysian construction industry’s view of the causes of corruption. Therefore, the arguments made in the study are influenced by the social, economic and cultural settings of Malaysia, which may limit generalisation of the findings. This paper helps stakeholders understand the root causes and underlying dimensions of corruption in the construction industry, especially in Malaysia. Recommendations for changing cultures that may be conducive to corrupt practices, and anti-corruption measures, are suggested based on the findings of the research. These findings can guide practitioners and researchers in addressing the impediments that give rise to the vulnerability of the construction industry to corrupt practices and understanding the “red flags” in project delivery.

Abstract: It is extensively acknowledged that excessive on-site electricity power load often causes power failure across a construction site and surrounding residential zones and can result in unforeseen schedule delay, construction quality problems, life inconvenience, and even property loss. However, energy management, such as power load optimization, has long been ignored in construction scheduling. This study aims to develop a modified shuffled frog-leaping algorithm (SFLA) approach in project scheduling to aid decision-makers in identifying the best Pareto solution for time-cost-resource trade-off (TCRTO) problems under the constraint of precedence, resource availability, and on-site peak electricity power load. A mathematical model including three objective functions and five constraints was established followed by the application of the modified SLFA on real-case multiobjective optimization problems in construction scheduling. The performance of SLFA was compared with that of the nondominated sorting genetic algorithm (NSGA II). The results showed that the developed new approach was superior in identifying optimal project planning solutions, which could essentially assist on-site power load-oriented schedule decision-making for construction teams.

Abstract: In order to accurately analyze the building energy consumption and identify the problem of building energy consumption in advance, this study carries out the energy consumption analysis based on BIM (Building Information Modeling). The research object is a four-story college student dormitory in Beijing, and this set of BIM-based energy consumption simulation data was obtained using standard operating procedures (SOP). This operating procedure can start energy consumption analysis in the conceptual design stage, and developers can participate in real-time through the use of a three-dimensional information model, without additional design required. Then, comparing this study with the traditional energy consumption analysis, we see that the SOP of this research result has the following advantages: SOP function analysis is more professional, and the visual display method is more popular and intuitive due to the flexible file format of the SOP, when data exchange is required between different software, the SOP can realize more convenient operation, and users can identify problems in the early stage of design through the SOP, correcting the scheme according to the simulation results, which is conducive to the development of the construction process. Finally, this study puts forward the analysis and estimation of energy consumption in different stages of the building life cycle, so as to provide researchers with ideas for improvement.

Abstract: Higher education institutions (HEIs) play a crucial role in fostering quality education. This paper examines the attributes that influence student learning experiences in a quantity surveying (QS) programme in a Malaysian private HEI and uncovers the underlying factors involved. The significance of these attributes as recognised by the students, obtained through a questionnaire survey, are subsequently presented. The findings reveal that the five most important attributes are closely related to the lecturer, namely the lecturer’s preparedness, responsiveness, interpersonal and communication skills, clarity and academic experiences. An exploratory factor analysis identifies the five major underlying factors to be the quality of academic learning to relate to professionalism and competency of lecturers, quality of academic services and support facilities, interpersonal connections and external considerations, curriculum structure and physical environment and facilities. Understanding these factors could help HEIs to devise effective strategies to enhance the quality of service and programme in higher education, which can result in a greater impact on the effectiveness of contemporary QS education and the reputation of the HEI as well as fostering student satisfaction and loyalty.
