Nowadays, Value Engineering (VE) is being widely practiced in many countries around the world. However, its concepts and applications do not seem to be well embraced in the Vietnamese construction industry. This study aims to seek solutions for promoting the development of VE in the Vietnamese construction industry. Most of the previous studies gave solutions in deficiencies and lack of analysis. On the basis of literature review and interviews with experts during the pilot test of the study at the initial stage, fifteen solutions were identified. A questionnaire survey was then conducted to rate the effective degree of the fifteen solutions. This study revealed six most effective solutions that should be taken with first priorities to promote the VE development. Additionally, the factor analysis method was applied to investigate the correlation effects of the solutions, which resulted in four core factors representing the solutions, namely, positive interest from government and construction stakeholders; education about VE; presence of VE organizations in the construction industry; and interaction with the outside world. The findings of the study are expected to bring the most effective solutions to promote the development of VE in the Vietnamese construction industry.

Integrated Project

Huge financial resources are spent in the construction industry all over the world, which are frequently wasted largely due to a lack of proper planning. In recent decades, in an attempt to overcome challenges, various contractual and administrative systems have been used by construction owners/clients. One such system has been Integrated Project Delivery (IPD). Its implementation has, however, experienced drawbacks. Identifying such drawbacks is an initial step in attempting to resolve them, and this paper aims to identify and prioritize the IPD implementation drawbacks in the context of the Iranian construction industry. A comprehensive list of IPD implementation drawbacks is prepared using a questionnaire survey. An in-depth literature review of the IPD concept has been combined with a review of various case studies applying the IPD system. The results were analyzed using the Robust Exploratory Factor Analysis (EFA) method. 22 drawbacks in the Construction Industry were categorized under four themes; contractual, environmental, managerial, and technical. Results show that contractual drawbacks are the most significant. The implication of this research is that identifying and classifying IPD implementation drawbacks provides a useful reference to managers and owners of the construction industry, for identifying and codifying solutions to overcome them.

PurposePrefabricated housing has become a boom industry across the world; however, the uptake of offsite construction (OSC) approaches in Australian low-rise buildings is rather low compared with high-rise buildings in other countries. This study aims to investigate and analyse the adoption of different levels of OSC approaches and the selection of different procurement options in Australian low-rise residential buildings.Design/methodology/approachThe research objectives were pursued through a mixed research method. An empirical questionnaire survey was carried out with 35 professionals in the Australian building and construction industry. Semi-structured interviews were conducted with 20 interviewees and analysed using thematic analysis method in NVivo software.FindingsThe research results found that the most suitable OSC level for Australian low-rise buildings is components-based prefabrication and identified the barriers to OSC uptake for each OSC level. The study also showed that the best option of procuring prefabricated products is from Australian manufacturers, followed by Australian suppliers/dealers and overseas manufacturers. Panelised prefabrication and components-based prefabrication are ranked as the most suitable OSC approaches for Australian manufacturers. Modular prefabrication is regarded as the most suitable for overseas manufacturer, while components-based prefabrication is the most suitable for Australian suppliers/dealers.Originality/valueThe selection of various OSC approaches and different procurement options in the low-rise residential buildings are scarcely explored topic, and thus, this study provides knowledge of interest for both researchers and practitioners.

Excess Amount

In recent times due to the Indian economic growth, there is a surge in construction activities. This surge has led to an excess amount of demolition waste that is produced. According to the Building Material Promotion Council, India generates an estimated 150 million tons of C and D waste every year. Some existing initiatives and the significant stakeholders' involvement have created the demolition waste management systems essential in the building’s demolition phase. The research in the C and D and Awareness program for C and D waste that initiated has led to the implementation of some waste management systems in the building's demolition phase. In India, the amount of demolition waste produced is higher than the construction waste produced while constructing buildings. So, it is essential for the demolition waste mitigation plan in the building's demolition phase. The study aims to know circular construction and current demolition waste management performance in the Indian construction industry. Through literature review, demolition waste management systems that are carried out all around the world are collected. The current practices carried out by different stakeholders practicing in India are known through a questionnaire survey. Data interpretation is made using the data collected in the literature review and the questionnaire survey. This research identified the significant benefits, barriers, and motivation factors to implement the waste management system, and proposing any necessary changes. Designer innovation and BIM deconstruction is considered as one of the barrier-breaking innovation in adopting the circular construction.

Off-site construction (OSC) methods have been widely adopted in the construction industry around the world. However, in a lot of developing countries, the application of OSC still lags behind. Although a number of research efforts have focused on identifying the OSC barriers, they are limited to qualitative descriptions, which lacks the understanding of the interrelationships among the barriers. To address this gap, this paper proposed a methodology for identifying the OSC barriers and their cause-effect relationships. The proposed methodology is composed of three phases: (1) a comprehensive literature review and in-depth interview with the OSC industry experts, (2) questionnaire survey and focus group discussion, and (3) grey DEMATEL analysis. The proposed methodology was applied in the context of China’s construction industry. The results of the grey DEMATEL analysis provided the cause-effect relationships of the 35 identified OSC barriers, which indicated six important aspects be taken into deeper consideration, such as governmental regulations and incentives, OSC practices and experiences, as well as traditional construction method transformation. The outcomes of this study will support policymakers and OSC participants to identify the influencing OSC barriers and their interrelationships, as well as propose appropriate strategies for overcoming the barriers and broadening the OSC application.

Over the course of more than a decade of the global economic crisis, the relevance of analyzing the performance indicators of construction organizations in the world has not only not decreased, but even vice versa - it has grown significantly, because now not only its success, but the most elementary survival in the current crisis depends on the financial condition of the company. Both the rate of recovery from the crisis and the competitiveness of the economy largely depend on the efficiency of the construction sector. Construction is a fund-forming (capital-intensive) industry on which the formation of the national economy depends; which means the formation of a complex economic, social, organizational, scientific and technical system. Currently, the construction industry of the Russian Federation is experiencing a number of difficulties in its development, but at the same time it has good chances of increasing its competitiveness and integration into the world market. The object of research of the article is the construction industry of the Russian Federation in the context of three main types of construction: construction of buildings; construction of engineering structures; specialized construction works. The article presents the author’s model of the profitability of fixed assets. The article describes one of the author’s methods of integral factor analysis, which allows an accessible and relatively simple assessment of the degree of influence of factors on changes in the studied indicator. The purpose of this article was to generalize and systematize the theoretical and methodological foundations of factor analysis in a form accessible to specialists in the field of economics and management, which should help form their basis for the development of economic thinking, understanding the essence of economic processes and phenomena occurring within the framework of the activities of economic entities. What is more important - it will help to develop skills for their quantitative assessment, economic interpretation and search for reserves to increase the efficiency of functioning.

AbstractContractors, among other construction stakeholders, are vital in achieving the set goals of a project. Adequately engaging a capable contractor is an important task for a client. This study aims at determining the reasons for clients contending with contractors that are not committed to health and safety (H&S). The study was conducted through a literature review, a questionnaire was developed and distributed to 286 construction stakeholders in the Nigerian construction industry. Cronbach alpha was used to test the reliability of the questionnaire used for data collection. Mean scores (MSs) were adopted to determine the major factors that influence clients’ selections and factor analysis was used to cluster variables of high inter-correlations. Findings from the survey reveal that H&S is not a clients’ goal or a project value hence, H&S is not viewed as a vital pre-qualification criterion for contractor selection. This results in a poor checklist concerning contractors’ quality assurance and inadequate verification of contractors’ H&S history. Therefore, appointing non-compliant H&S contractors. The findings provide information on the influence clients have respecting H&S as a prequalification criterion and towards construction workers’ H&S. This will enable construction stakeholders to make the right decision in the pre-qualification of contractors.

Capital Demand

Women’s involvement in the Indonesian construction industry is considerably low accounting for less than 3% of the total workers. Construction as a male-dominated industry becomes a barrier for women to join the workforce. The increase in the need for workforces is proportional to the growth in construction development. The needs cannot only be provided by male workers. Women's participation in the construction industry will contribute to the shortage of human capital demand. The aim of this research is to find the factors that impede women to pursue their careers in the construction industry. 21 factors are gathered from an extensive literature review. After conducting expert interviews, the factors are developed into a questionnaire and distributed to women who are already in the workforce. The analysis based on the Relative Important Index shows that the most influential barrier to women in construction is the lack of worksite security. The factor analysis found five critical barriers to women’s careers in the construction industry. Developing these barriers to a framework gives a broader perspective about the sources of each critical barrier. Internal as well as external elements including worksite, organization, and the industry itself have been the cause that prevents women to pursue their careers in the construction industry.
