Abstract Construction industry is one of the most hazardous industries to work in. This problem is further exacerbated by the fact that safety performance improvement is stagnating. Information technologies (ITs) are however identified as one of the most promising methods of improving the performance of construction safety. The goal of this paper was therefore to present previous research in the application of innovative ITs to the field of construction health and safety (H&S), classified by their underlying technology and application, to identify research gaps, as well as to evaluate and describe the potential of their implementation into construction safety practice. To achieve the set goals, the research consisted of identifying and studying the existing research published in the leading journals in the field of construction H&S. The review identified 72 papers dealing with development or application of innovative ITs. The research had also identified several research gaps, which have a significant impact on the construction safety practice. These gaps focus on the construction phase, while neglecting earlier project phases; industry and project levels, while neglecting construction activity and task levels; building projects, while neglecting infrastructure projects and specific hazard types, while neglecting a universal approach. Focussing research effort on these gaps would benefit all construction safety stakeholders but mostly the prominent contractors and H&S professionals. Furthermore, recommendations for directing research focus on solving the identified issues are given in this paper.

Abstract Today’s level of globalization and intensifying of competition have resulted in increased number of companies that aim to internationalize their business, and internationalization is gaining more and more significance among the research community. There are not only many perceived benefits of conducting business activities outside one’s home country but also additional risks, challenges and barriers. Construction industry is specific in its nature as it is an extremely regulated profession. This presents an additional challenge to the construction companies seeking to internationalize their business. The goal of the paper is to analyze the current levels of internationalization on the global construction market and to gain insight into future trends, which are achieved by analyzing business data regarding the international construction sector and the data on international results of the Croatian construction companies. The paper first presents the development of the international construction market, followed by the report on the current state of the internationalization in the construction industry as well as on future trends. Finally, the paper presents an overview on the Croatian construction companies and their performance on the foreign markets and gives guidelines or potential growth strategies to participate on the foreign markets.

Abstract The function of project risk management (PRM) is to understand the uncertainty that surrounds a project and to identify the potential threats than can affect it as well as to know how to handle these risks in an appropriate way. Then, the measurement of the performance of PRM becomes an important concern, an issue that has not yet been addressed in the research literature. It is necessary to know how successful the application of the PRM process is and how capable is the process within the organization. Regarding construction projects, it is essential to know whether the selected responses to mitigate or eliminate identified risks were suitable and well implemented after the execution of the project. This paper presents a critical analysis of the relevance of measuring the performance of PRM and the benefits of doing so. Additionally, it presents a preliminary and pioneering methodology to measure the performance of PRM through the evaluation of the adequacy of responses applied to mitigate risks as well as to evaluate the resulting impacts as indicators of the effectiveness of these actions at the end of the project. This knowledge will allow construction companies to incorporate good practices, generate lessons learned, and thereby to promote a continuous improvement of the whole PRM process.

Abstract Supply chain management (SCM), for the past two decades, has been identified by manufacturing industries as a new way of doing business. Construction, similar to manufacturing and other services industries, is experiencing emerging trends that are aimed at giving ultimate satisfaction to the end user. Lean construction is a way to design production systems in order to minimize waste of materials, time and efforts which generate maximum possible amount of value. This research looked into how SCM can benefit the Ghanaian building construction industry through the application of lean concept. The purpose of this study is to assess the level of collaboration and coordination in planning of activities among construction industry players and investigate into the sources of waste in construction. The study, employing survey and case study approaches, collected data through structured questionnaires, in-depth interviews and direct observation of ongoing projects on KNUST campus. One sample t-test was used to analyse the data. The findings pointed out that the level of coordination and collaboration in planning among industry players were very appreciable though there still exist room for improvement.

Abstract Bangladeshi construction industry suffers more safety issues than other developing countries in the world. Among many of these, accidents at the construction site go far beyond and shape a horrific figure of death every year. The aims of this study are to identify and prioritize the causes of accidents. This study also analyses and discusses causes of accident at the construction site in Bangladesh. A widespread literature review and open discussion took place to identify the causes and design the questionnaire. The questionnaire-based survey was used to elicit the attitude of four stakeholders such as workers, owners, consultants and contractors towards the causes of accident. Mean and relative importance index (RII) were used to determine the rank of causes, and Statistical Package for the Social Sciences (SPSS) 23 was used to perform the data validation test. This study identifies 77 causes under 14 major groups and ranked them based on the mean and RII. The top five major groups of causes are management-, consultant-, technology-, labour- and contractor-related causes. The top five causes are unawareness of safety-related issue, lack of personal protective equipment, lack of safety eliminating/avoiding design, unfit equipment, lack of knowledge and training on equipment. This study will help the project participants and authorities to know and understand the various characteristics and linkage of causes of construction accidents to improve the construction safety management. It contributes to the body of knowledge, as it reveals for the first time the causes of accidents in the Bangladeshi construction industry.

Abstract Development and certification of buildings for health and safety of building users necessitated the building control and regulations agencies in Nigeria, and the protection of the built-up regions from human injuries is man’s major obligation. The article aims to determine and assess the level of practice of building control and regulations in the country with a view to advance their practice. A questionnaire instrument was used, and 35 building control performance indicators were recognized, and categorised into four groups and assessed. A total of 117 questionnaires were distributed to survey participants. Statistical tools of mean, chi-square, Kendall’s coefficient of concordance and Kruskal–Wallis test by Statistical Package for the Social Sciences v.23 were used. The result obtained revealed that the level of practice of the four groups of building control performance indicators is average. On the basis of the survey findings, the top most five building control performance indicators as considered by the participants are as follows: zero tolerance to illegal development and building collapse, enforcement of building control regulations, processing and scrutinizing of building plans for approval, cooperation among staff members and public enlightenment on building control and regulations. The degree of agreement between the participants concerning the performance indicators that influence building control and regulations practice in Nigeria was established. The result obtained revealed that there is a statistically significant degree of agreement among the three different classes of project managers regarding their responses. The study also revealed the drawback in the implementation and enforcement of building control and regulations in the country. Recommendations were also made to improve the practice.

Abstract This article examines the effective road reconstruction technologies applied during construction processes to ensure the required final quality of construction work. The construction quality and especially the overall levelness of roads are influenced by several factors. These factors include high-quality implementation of road structural layers, including active zones, which can be adversely affected by the undisciplined application of technology, insufficient engineering and poor geological surveys. Suitable and effective reconstruction technology provides the required quality of construction work yet does not significantly extend construction time. The authors propose stabilisation using cement or lime during reconstruction. This stabilisation method is used if the structure of the bedrock layers is finely granular. The stabilisation process consists of excavating the unacceptable bedrock layer and mixing it with additives and water. A principally different bedrock stabilisation method consists of completely replacing it with a gravel layer, which is used when individual base layers are diverse and stabilisation using additives would not guarantee the required results, i.e. improved strength characteristics. In some cases, the existing base layers are not suitable for use as road base layers because of their characteristics, such as volumetric instability. For this reason, they must be replaced with more suitable materials. This topic is documented by a practical example.

Abstract Mega transport infrastructure projects are frequently perceived as critical to the “success” of major metropolitan, regional and national development because of their potential to affect significant socioeconomic and territorial changes. However, the mega infrastructure development literature tends to focus upon the frequent failures of such projects because of their inability to meet their original expectations. A major cause for such perceived underperformance has been attributed to the inadequacies of ex-ante project appraisal methodologies. In particular, their excessively narrow focus has prompted growing calls for broader and more transparent project appraisal frameworks. These calls coincide with a period where public private partnerships (PPPs) are growing in importance globally as the favoured procurement route for governments looking to undertake new mega transport infrastructure developments. Some see the practicalities of PPPs as placing them at odds with aspirations for more inclusive and open project appraisal with adequate consideration of the public interest. It is the authors’ contention that if introduced with broader and more systematically presented sustainability concerns, PPPs can remain compatible with such ambitions. Towards this end, this paper presents the rudimentaries of a policy-led multi-criteria analysis (PLMCA) approach to project appraisal as a means by which PLMCA can contribute to more holistic PPP procurement practices. The authors contend in the latter part of the paper that PLMCA addresses many of the limitations associated with the application of narrower decision-making and project appraisal approaches currently supporting PPPs and other more conventional procurement practices.

Abstract Background and problem Integrating lean and green principles while implementing construction project has become an important aspect of modern construction. Lean construction and green building are used to maximize the economic benefits, address quality, reduce waste and minimize the negative environmental impacts in construction. Aims The objectives of this paper were to measure the degree of knowledge of lean and green approaches in construction industry in Gaza Strip and to identify the most important benefits from application of lean and green in construction. Methodology Literature review and questionnaire survey were used in this study. A total of 155 copies of the questionnaire were distributed randomly to owners, consultants and contractors in the Gaza Strip, and 119 copies of the questionnaire were received. Results The results revealed that the awareness level of lean and green construction by owners, consultants and contractors in the construction industry in Gaza Strip is moderate. There are very important benefits of applying lean and green construction such as “reduce non-useful work that does not add value to work”, “reduce the environmental impact of the construction process” and “saving the money needed to complete the project”. Conclusions It was concluded that integrating both concepts on projects showed that lean leads to green but not necessarily vice versa. The fields of lean and green thinking, however, have been developed largely independent of each other. There is a big gap in the knowledge and application of the lean construction and the green application.

Abstract Purpose Recent studies show that lowest bidder technique is mainly used in developing countries such as India to award a contract. It has been demonstrated that the lowest bid is not always the accurate one and can lead to cost overruns and time extensions amongst other problems. The aim of this study was to investigate the critical factors impacting contractor’s efficiency in Indian construction projects. Research approach A survey was sent to participants of construction projects awarded by the government with the lowest bidder technique in Uttar Pradesh, India. For further research, snowball sampling was used, and structured interviews were conducted amongst experienced managers and engineers of these projects on both client’s and contractor’s side. Findings It was observed that, to a greater extent, the delays were caused due to contractor’s opportunistic behaviour. The main findings are that new bidding methodologies are to be tested as they can lead to the choice of a more accurate and realistic bidder.

{"title":"An analytical study of critical factors affecting contractor efficiency in construction projects in Indian scenario","authors":"S. Deep, Laura Simon, M. Asim, A. Rahimzadeh, Sulala Al-Hamdani","doi":"10.2478/otmcj-2018-0010","DOIUrl":"https://doi.org/10.2478/otmcj-2018-0010","url":null,"abstract":"Abstract Purpose Recent studies show that lowest bidder technique is mainly used in developing countries such as India to award a contract. It has been demonstrated that the lowest bid is not always the accurate one and can lead to cost overruns and time extensions amongst other problems. The aim of this study was to investigate the critical factors impacting contractor’s efficiency in Indian construction projects. Research approach A survey was sent to participants of construction projects awarded by the government with the lowest bidder technique in Uttar Pradesh, India. For further research, snowball sampling was used, and structured interviews were conducted amongst experienced managers and engineers of these projects on both client’s and contractor’s side. Findings It was observed that, to a greater extent, the delays were caused due to contractor’s opportunistic behaviour. The main findings are that new bidding methodologies are to be tested as they can lead to the choice of a more accurate and realistic bidder. In addition, subjective evaluation components, such as schedule and work-force, should be reflected in contract award methods in addition to the cost criteria. Further studies should be performed on the choice of contract awarding methodology based on the project size and type.
