The Mean

The failure of construction projects could be attributed to several challenges that emerged during the construction process. Nine major challenges were uncovered from the literature: resource allocation, time, cost, quality, safety, project complexity, changes, uncertainties, and communication. A survey was carried out among professionals having a minimum of 10 years of experience in the construction industry to identify the occurrence and severity of these challenges. A total of 117 responses were analyzed and plotted on a risk matrix. The mean values indicated that time, cost, and quality are the top three challenges faced in construction projects, while the risk matrix revealed that all challenges are high-risk challenges. Thus, the professionals should consider suitable measures to address these challenges for improving a project’s performance.

Design Bid Build

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.

Degree Of Control

Dispute occurrence on construction projects is almost inevitable. If not addressed adequately, disputes can cause contract termination and loss of benefits for all parties involved. Among various dispute resolution methods, mediation is gaining popularity in the construction industry as it satisfies the desired degree of control of both parties among other factors (e.g., time, cost). Mediation is a cooperative problem-solving method that benefits from the expertise of a neutral third party known as the mediator. Well-defined tactics such as creating trust atmosphere, tackling the core of dispute, and using advanced integrative approach for solution determination are essential to reduce the gap between disputants and ensure effective discussions. The aim of this paper is two-fold. First, it investigates common mediator tactics and relates them to the likelihood of having a successful mediation. The San-Ramos Channel case study is used to illustrate the efficiency of mediator tactics. Second, this paper takes a closer look into the use of mediation in Lebanon as an example of a country with minimal regulations on mediation. Barriers for an effective implementation of mediation such as the role and the influence of the engineer on the construction process and the mediator’s lack of technical expertise are discussed and recommendations are derived.

PurposeProject managers work to ensure successful project completion within the shortest period and at the lowest cost. One of the main tasks of a project manager in the planning phase is to generate the project time–cost curve, and furthermore, to determine the most appropriate schedule for the construction process. Numerous existing time–cost tradeoff analysis models have focused on solving a simple project representation without regarding for typical activity and project characteristics. This study aims to present a novel approach called “multiple-objective social group optimization” (MOSGO) for optimizing time–cost decisions in generalized construction projects.Design/methodology/approachIn this paper, a novel MOGSO to mimic the time–cost tradeoff problem in generalized construction projects is proposed. The MOSGO has slightly modified the mechanism operation from the original algorithm to be a free-parameter algorithm and to enhance the exploring and exploiting balance in an optimization algorithm. The evidential reasoning technique is used to rank the global optimal obtained non-dominated solutions to help decision makers reach a single compromise solution.FindingsTwo case studies of real construction projects were investigated and the performance of MOSGO was compared to those of widely considered multiple-objective evolutionary algorithms. The comparison results indicated that the MOSGO approach is a powerful, efficient and effective tool in finding the time–cost curve. In addition, the multi-criteria decision-making approaches were applied to identify the best schedule for project implementation.Research limitations/implicationsAccordingly, the first major practical contribution of the present research is that it provides a tool for handling real-world construction projects by considering all types of construction project. The second important implication of this study derives from research finding on the hybridization multiple-objective and multi-criteria techniques to help project managers in facilitating the time–cost tradeoff (TCT) problems easily. The third implication stems from the wide-range application of the proposed model TCT.Practical implicationsThe model can be used in early stages of the construction process to help project managers in selecting an appropriate plan for whole project lifecycle.Social implicationsThe proposal model can be applied to multi-objective contexts in diversified fields. Moreover, the model is also a useful reference for future research.Originality/valueThis paper makes contributions to extant literature by: introducing a method for making TCT models applicable to actual projects by considering general activity precedence relations; developing a novel MOSGO algorithm to solving TCT problems in multi-objective context by a single simulation; and facilitating the TCT problems to project managers by using multi-criteria decision-making approaches.

Variation order refers to any changes from the scope, plan, specification or contract document in the construction project. This changes of work is a common problem in construction projects in Malaysia. It is inevitable in any construction project and this problem can become more serious when variation order causes work progress to be impaired as a results it increased the construction time and cost that affects the construction industry in Malaysia. This paper critically review the causes of variation order in the construction industry on the double-storey terrace housing project in Malaysia. The discussions began with the construction industry in Malaysia and then related parties involved in the construction industry. The extensive local and abroad literature review on the definitions of variation order and analysis of past studies conducted on variation order and the previous study of the prediction model of variation. The extensive literature on variation order in the construction of building project may help to improve the performance in term of time, cost and quality of the construction of building projects in Malaysia.

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.

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.

In Malaysian construction industry, Industrialised Building System (IBS) has been introduced to replace the traditional construction method. While the government has been making significant efforts to encourage the IBS adoption, the uptake of IBS in Malaysia construction projects remains low. This study seeks to identify the barriers to the uptake of IBS and to propose the strategies to enhance the implementation IBS in Malaysian housing construction process from the perspectives of consultants. Interviews were conducted with five selected experienced individuals who were working with consultants (civil and structure engineer and quantity surveyor). The results revealed that, lack of knowledge and insufficient skilled workers are the main factors that impede the IBS uptake in Malaysia. Meanwhile, the most strategy proposed by the interviewees is to increase the facilities and incentives in order to expand research and development in IBS.
