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.

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.

Abstract A construction project is like a living entity and requires the interconnection and coordination of several stakeholders and many of them have their objectives, which sometimes create a conflict of interest between the teams and within the teams. The success of any project is repeatable, and a set of attributes for the success of a construction project can be identified, requiring discipline and hard work. The construction sector is the engine of growth for a nation and supplies services and goods to other industries. The objective of the study is to analyse the enabling factors affecting the performance construction projects in Architecture Engineering and Construction industry. The methodology chosen for the study is to collect primary data from the Indian construction industry using structured questionnaire surveys. The collected data are analysed using reliability and factor analyses. The findings of the study provide the value of reliability, that is, Cronbach's alpha value of (0.86) of the data collected using a questionnaire survey. Furthermore, exploratory factor analysis produced five main significant factors based on covariance between the attributes and grouped into factors such as site management and coordination, leadership and financial management, planning, commitment, and coordination having a variance of 17.65, 11.8, 9.1, 8.5, and 7.5%, respectively. This article is the extended version of the paper accepted and presented at CCC2019.

Dispute is recognized as critical cause of deficiency and low performance in construction projects. Plenty of studies have been done in construction dispute management recently; however, there are no studies on construction dispute elimination. This study aims to propose a building information modeling (BIM) approach to control conflict causes before the occurrence of dispute. BIM is one of the latest platforms that promote a high level of collaboration, information sharing, and coordination where its implementation ranges from project initialization to completion stage. The circumstances associating with BIM technology can be utilized to explore the possibilities in conflict and dispute resolution system. Questionnaire surveys are used to collect the primary data. Analytical hierarchy process (AHP) and multi attribute utility technique (MAUT) are adopted to develop an algorithm and a decision-making framework to manage and resolve the potential conflict causes, particularly for the Malaysian construction industry. Data analysis emerged that five critical conflict factors in Malaysian construction industry are insufficient monitoring of CPM scheduling and updates requirements; failures to understand and correctly bid or price the works; delay in running bill payment; inadequate contractors’ management, supervision, and coordination; and error and omission in design that are originated from time, cost, quality, and documentation. Further analysis to prioritize BIM functions in construction conflict management has been done by the combination of AHP and MAUT results. Consequently, it is affirmed that clash detection and cost estimating, 4D scheduling, 3D visualization and structure analysis as BIM functions obtained the highest score to control conflicting factors.
