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.

The value, care, and customs of workers are essential in terms of occupational health and safety. The abuse of alcohol is widely regarded as a serious threat to the lives, health, and safety of employees. The aim of the research was to identify the main problems that are associated with alcohol abuse and consumption at work among employees in the construction industry, with particular emphasis on workstations where work is carried out on construction scaffoldings. Data for the analysis were obtained from two different sources. The first one was post-accident documentation on occupational accidents. The second one was surveys collected during the research project. This study confirmed that excessive and disproportionate alcohol consumption can be the cause of an accident, and consequently death at workplaces with scaffolding. Of 219 accident reports, 17.4% indicated alcohol as a contributing factor. Analysis of accident documentations shows that in cases where alcohol was indicated as a contributing factor in an accident, the alcohol was consumed during the workday. The results obtained on the basis of the conducted research were able to constitute a justification for the directions of preventive actions carried out in order to reduce the number of occupational accidents in the construction industry caused by alcohol.

Purpose The state of the different practices in construction industry determines its performance level. Hence, improving performance of construction industry needs assessing state of the practices in the industry and devising improvement intervention. The purpose of this paper is to measure improvement requirement level of different construction management practice areas and to identify the underlying improvement dimensions in Ethiopian construction industry. Design/methodology/approach Questionnaire survey was developed for data collection based on a thorough literature review which yielded 28 construction management practice areas. Purposive sampling method was used to select respondents for the survey. Mean score was used to identify the required improvement level, and one sample T-test was carried out to identify significance of improvement requirement. Factor analysis was conducted to identify the underlying dimensions of the construction management practice areas. Findings Findings indicate 27 areas need significant improvement. This shows the low level of adoption of good construction management practices in Ethiopian construction industry. Factor analysis resulted in the areas being grouped to four broad improvement dimensions, namely, project management, organization management, knowledge and risk management and project development and contract management. Originality/value The findings provide information for appropriate action by the stakeholders to raise standards of adopted construction management practices. It also show areas of construction management which require more focused research in the context of Ethiopian construction industry. Considering the similarity of nature of construction industry problems in developing countries, the findings can be extended to similar countries.

Purpose – The purpose of this paper is to evaluate the waste occurrence level in the construction industry. It includes: first, identifying the mean value of frequency of waste occurrence according to respondents’ characteristics; second, identifying the main predictive factors for waste occurrence based on latent relationships between initial waste factors; and third, identifying the waste occurrence-level indicator (WOLI) for the construction industry based on the main waste measurement factors. Design/methodology/approach – A total of 19 waste factors were sorted from the literature review. A structured questionnaire was adopted to carry out the survey. The respondents are professionals who have much experience in construction and management of project. Shapiro-Wilk test of normality, Levene’s test, ANOVA test, and factor analysis technique were used to analyze the collected data. Findings – Frequency of waste occurrence in construction projects is quite high. There was no statistically and practically significant difference in means for waste occurrence between selected population categories. Based on factor analysis technique, there were five principal components extracted with 56.7 percent of total variance. The WOLI in the construction industry was found as 61.55 per the scale of 100. Research limitations/implications – The non-probability sampling was applied to collect data because of several certain limitations and difficulties. The number of data sets is relatively small. This study has only examined the frequency of waste occurrence without quantitative information. Practical implications – This is another study of waste factors in the construction industry, which is different from traditional waste studies. Originality/value – The contribution of this study to the practical project management is that a proposed evaluation sheet for WOLI could be applied for any construction firm.

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.

Construction is one of the leading economic activities. The organization of the construction industry ensures the focus of all organizational, technical and technological solutions to achieve the end result, i.e. the commissioning of a facility of the appropriate quality within the established deadline. The image of the territory is of great importance for the investor, because it is very risky to invest one’s resources and to know in advance that the territory has a negative reputation. There are a lot of territories in the Irkutsk region and in Russia as a whole that require integrated development, as the city center is built up fairly densely and it proves to be rather difficult to buy accommodation or build a facility there. Therefore, the development of the territory outside the city is of vital importance. Thus, managing the investment attractiveness of the comprehensive development territories of the municipalities is relevant.

Exploratory Factor Analysis (EFA) was carried out to develop appropriate questionnaire items as research instruments. This study has developed and certified the instruments of safety management commitment and safety administration through the EFA study. It is applied in the context of occupational safety and health management (OSH) of construction industry. This study was divided into two constructs namely Safety Management Commitment (SMC) and Safety Administration (SA) to measure safety attitude. Safety administration construct was measured by safety programs and safety monitoring. Whereas, safety management commitment construct was measured by safety planning and safety management. This study was conducted to evaluate the contractor’s safety management attitude to the safety culture at the construction site. About 100 respondents were selected through simple random sampling to fill out the survey. Based on the reliability test, this study has set an instrument consist of eight items to develop two components for the construct of safety management commitment. While, for the construct of safety administration consist of six items for two components. This setting is based on the internal reliability value (Alpha Cronbach) for measurement of the instrument. The procedure is described in detail to carry out an EFA analysis to develop the instrument’s construct of SMC and SA. For the future, researchers can develop a study by applying instruments thoroughly in various fields of research.
