Disputes are unavoidable in construction projects due to their complex characteristics and involvement of different parties, which can interrupt the smooth construction process. Hence, proper dispute avoidance strategies need to be implemented to avoid disputes beforehand. On the other hand, the previous researchers suggested that there is a link between disputes and procurement methods. Therefore, the current research investigates the disputes in the construction industry from the perspective of different procurement methods. A systematic literature review was carried out to identify the available procurement methods in the construction industry, disputes and dispute avoidance strategies and the features of the procurement methods from the perspective of disputes. Firstly, a total of fifty-two key research papers on the research area were employed to review. The literature findings revealed that the industry has moved towards collaborative approaches from the traditional procurement method with higher dispute frequency because as per the findings the likelihood of disputes seems less in the projects procured under collaboration. It further revealed that the inherent features of collaborative approach such as teamwork, relationships and mutual understanding give less prosper towards disputes. Therefore, the findings of the review conclude that the selection of collaborative procurement method at the early stages of a project can reduce the possibilities of disputes from the perspective of procurement methods.

Design-Bid-Build (DBB) or commonly known as Traditional method is the earliest and most prevalent procurement method used in Malaysian construction industry. Design-Build (DB) and Construction Management (CM) procurement methods were later introduced in Malaysia as an endeavour to satisfy and accommodate the increase in project complexity and the need for avoiding drawbacks of the Traditional methods. Each procurement method has different nature and possesses certain characteristics. Therefore, this study was carried out to ascertain and compare the characteristics of these three procurement methods that are implemented in building construction projects in Malaysia. A questionnaire survey was conducted among architects, consultants, contractors and owners or developers to elicit their feedback on the characteristics which were categorised into time, cost, quality, complexity and flexibility, degree of involvement and responsibility allocation and technical expertise. The findings indicated that only DB method almost fulfils all the characteristics under the six categories, whereas, DBB methods garnered agreement only for certain characteristics under time, cost, complexity and flexibility and technical expertise categories. Meanwhile, the only CM method’s characteristics that satisfy agreement from the respondents are the often used of fast track approach and lack of certainty in price. This study concludes that when a procurement method is adopted for a construction project, not all the features or characteristics will turn out as expected. There are many factors that contribute and are influential on the success in procurement methods that are worth for further investigation.

AbstractOne of the key problems in managing the realization of a construction project is the selection of appropriate working crews and coordinating their activities in a way that ensures the highest degree of implementation of defined goals (minimizing the project duration and/or reducing downtime and related costs). Most of the existing methods of work harmonization used in construction industry allow obtaining the desired results only in relation to the organization of the processes realization in repetitive linear projects. In case of realization of non-linear construction objects or construction units, it is usually necessary to choose between the reduction of the project implementation time and maintaining the continuity of crews work on the units. It was found that there is a lack in the literature of developed method enabling harmonization of crews’ work, while minimizing the downtime at work and the duration of the entire project taking into account additional constraints, e.g. the need to not exceed the deadlines for the realization of the project stages.The article presents the concept of a multi-criteria optimization method of harmonizing the execution of non-linear processes of a multi-unit construction project in deterministic conditions. It will enable the reduction of realization time and downtimes in work, taking into account the preferences of the decision maker regarding the relevance of the optimization criteria. A mathematical model for optimizing the selection of crews and order of completion of units in multi-unit construction projects was also developed. In order to present the possibility of usage of the developed concept, an example of the optimal selection of crews and their work schedule was solved and presented. The proposed method may allow for better use of the existing production potential of construction enterprises and ensure synchronization of the crews employed during the work, especially in the case of difficulties in acquiring qualified staff in construction industry.

Construction projects often are particularly susceptible to conflicts due to their long-term character and complexity. In Germany, courts must deal with around 100,000 construction dispute litigations per year. Alternative Dispute Resolution (ADR) can be an alternative to expensive as well as time-consuming litigation and can help to relieve the judicial system. Furthermore, ADR may contribute to the satisfying settlement of a dispute between parties involved in the construction process and thus help to reach construction projects’ completion on time and within budget. Often, ADR mechanisms such as adjudication, mediation, and conciliation will be used. The paper analyzes the development of ADR in Germany in conjunction with European legal aspects. With special reference to the construction industry practice in Germany, various ADR measures and their advantages and disadvantages, as well as the current situation, will be explained. The authors conclude that, although ADR in Germany has experienced an upswing since the 1990s, it is used only to a small extent for settling disputes in construction projects. An increased knowledge about the advantages and disadvantages of different ADR measures in the construction industry would lead to more frequent uses of ADR. That, and a clever and detailed contract design, which helps to avoid conflicts basing on unclear contract contents, could save money and relieve the courts from time-consuming legal proceedings.

Prefabrication has been widely adopted in the construction projects in recent years. It has also been advocated as a greener and more sustainable approach of project delivery. However, with a wealth of evidence supporting other reasons as the drivers of using prefabrication, it is questionable whether the real goal of prefabrication is to achieve sustainable construction. This study aims to investigate the roles of prefabrication in fostering sustainable construction. The effectiveness of prefabrication on fostering sustainable construction was evaluated on the five aspects enlisted by the UK’s Green Construction Board: Waste, Water, Carbon, Materials, and Biodiversity. An industry survey was conducted in Melbourne, Australia for data collection. 200 questionnaires were sent via email or post to a variety of fields within the construction industry. Entropy ranking analysis was adopted to analyze the effectiveness of using prefabrication in construction. The results suggest that prefabrication is effective in reducing construction waste and sourcing energy efficient materials. However, the utilization of prefabrication was found unsuccessful in reducing carbon emissions during the construction process. It is suggested that proactive actions should be taken at the design stage to unleash the potential of prefabrication in construction.

Prime contractors rely heavily on subcontractor services to lower costs and increase efficiency on construction projects. Subcontractors perform certain tasks that the main contractor cannot perform efficiently. To get a competent subcontractor, it is necessary to hold the selection of subcontractors. The selection of subcontractors becomes very important in keeping pace with the growth of the construction industry, so the main contractor as the construction executor requires a subcontractor or specialist contractor for certain jobs that require specialized expertise. This study was conducted by reviewing the findings of several related scientific journals, so that the factors that influence the selection of subcontractors and the most influential factors are the experience of doing similar work. In addition, it also found its effect on the time of implementation of the project.

Changes in construction projects are very frequent and are expected to occur at any stage of the project. These changes modify the original scope of work and affect the project in various aspects. To minimize these effects, there is a need to implement a systematic change management system during the construction process. This study aimed to investigate the current situation of change management implementation, identify the main causes of change management, and assess their impacts in the Congolese construction industry. A comprehensive literature review was conducted for a thorough understanding of change management, and a structured survey was conducted. The collected survey data were analyzed using the relative importance index (RII), and Statistical Package for the Social Sciences (SPSS) methods. The results conclude that the change management implementation situation in the Congolese construction industry is significantly high, and the project cost and the project type play a major role in the implementation of change management in the construction projects. The study further revealed that the main causes of changes were the project, contractor, materials, equipment, and other causes. These changes impact the project significantly in terms of organization, owner and contractor, project, materials, and equipment.
