Waste disposal has become an issue worldwide and the major cause of this issue is considered to be the construction activities producing wastes. Pakistan being the 6 most populated country in the world is considered to have a huge amount of waste due to the various construction and particularly megaprojects and this amount of construction waste is increasing consistently in the country. Pakistan produces of construction waste per year and is increasing annually by 2%. These increasing wastes and issues associated with these construction wastes lead to a crucial need for improvement of waste management practices in the construction industry of the country through various measures. Despite of the large need for waste minimization research in Pakistan, , deductive approach was used, and quantitative method was selected, the present study has used cross-sectional design. The researcher used a sample of 323 individuals and conducted a questionnaire-based study.

Hong Kong is a densely populated city with high-rise developments, and as in other metropolitan cities, the amount of waste generated from construction projects in the city is increasing annually. The capacity of existing landfills is expected to be saturated by the 2020s. Construction waste management has been implemented for years but the performance is still not satisfactory. The aim of this research paper is to explore and formulate strategies and measures for effective construction waste management and reduction in highly urbanized cities such as Hong Kong. A desktop study on construction waste management practices was carried out for a preliminary understanding of the current situation in Hong Kong. Semistructured interviews and focus group meetings were further conducted to shed light on how to improve construction waste reduction and management in Hong Kong. The main contributions of this research study are the potential short-term, medium-term, and long-term strategies, which are related to the design stage, tender stage, construction stage, and government support. The five major strategies recommended are financial benefits to stakeholders, public policies in facilitating waste sorting, government supports for the green building industry, development of a mature recycling market, and education and research in construction waste minimization and management.

Purpose The complicated nature of megaprojects requires appropriate analysis of multiple stakeholders to achieve project objectives and to accommodate stakeholder interests. During the last two decades, many stakeholder theories and empirical studies have sprouted. Although previous studies have contributed to the development of stakeholder theory, it seems that these theoretical advances have not been fully adopted and acknowledged in practices, especially in megaprojects. The purpose of this paper is to explore the evolution of stakeholder analysis and engagement practices adopted in the Australian megaprojects over the last two decades. Design/methodology/approach Four mega construction projects are described and analysed in this study. Secondary data were first assembled in order to get general knowledge of each case. Interviews were conducted with the project directors. Project documents were collected from the project teams and reviewed. Wherever the project information was unclear, e-mails were sent to the directors and the team members to confirm the details. Findings Project teams have started to apply snowball rolling and stakeholder attribute assessment methods to analyse stakeholders. However, there is still a way to adopt the “network” analysis perspective because the project teams are reluctant to use complicated tools which need specialists’ assistance. The stakeholder engagement practices have evolved to an extent where the project teams monitor the dynamics of stakeholders’ requirements. Projects teams have identified the importance of continuity to manage stakeholders in these massive projects. However, a structured method selection mechanism for stakeholder engagement has not been developed. Originality/value This study will help academics to understand the adoption progress and status of stakeholder management methods.


As the intricacy of construction projects is amassed, prospects for tribulations are mounting, depicting negative impact on projects’ cost, time and excellence. Thus, eliciting claims that aredisruptive to projects, time consuming and exorbitant. BIM holds enormousprobable in prosperous claim management practices. The progression of BIM can enrich knowledge sharing for information of a building or facility. It forms a vitalbase for decision making throughout the life cycle phase from the conceptual design to demolition. BIM is also, a valuable multidisciplinary cohesive source of information technology that posts benefits and disputes in the construction industry. The main aspiration of this paper is to appraise how and to what magnitude BIM can help evading and plummeting claims in Jordan construction industry.The paper ran a literature review on recent research, industry reports, and other sources to seehow they identified claims, its classifications, benefits, impacts and challenges of BIM on construction projects.Also, the paper acknowledgedcontemporaneous challenges in the claims field and the construction industry as whole. The attained outcomes have shown that BIM overtakes traditional claim management practices in many aspects including recognizing and investigating claims, where the benefits are comprehended in time and cost savings, less change orders, less rework. Moreover, the information and knowledge management that BIM postulates can improve many aspects of claim management.

Purpose Knowledge management (KM) is the central know how for the construction industry. However, the delivery of construction projects is often plagued by schedule delays and cost overruns due to lack of working knowledge of project personnel. Hence, the need to appraise the practices of knowledge management in the construction industry has become all the more germane. This paper aims to determine the awareness of KM practices in Malaysia-based construction small and medium enterprises, and to investigate the benefits, tools and techniques, and challenges associated with knowledge management implementation so that effective measures can be devised to address them. Design/methodology/approach The research data were gathered using a structured questionnaire survey disseminated in the Klang Valley region in Malaysia. Responses were collected from 107 industry practitioners. The quantitative data are subjected to descriptive statistics, and the ranking with category of significance of the hypothesised variables is determined using the relative importance index (RII) technique. Findings The key benefits of KM practices are predominantly raising efficiency, quality, productivity and decision-making. The most preferred KM techniques are “face-to-face interaction”, “mentoring” and “documents and reports”. The highly significant tools are “groupware” and “telephone”. The major organisational issue hampering the implementation of knowledge management practices is “lack of motivation” while the critical cultural issue is relating to “bureaucracy and hierarchical”, and the vital people issue concerns “lack of trust”. Research limitations/implications The respondents were limited to only small and medium construction enterprises located in the Klang Valley region in Malaysia, which makes generalisation challenging. Practical implications KM provides not only a pragmatic but also a proactive approach to raising the competitive edge and capabilities of a construction company. Identification of the critical attributes of KM provides the basis for project managers in formulating KM strategies to enhance the chances of successful delivery of future projects. Originality/value The study contributes to the debate on the knowledge agenda in the construction industry, particularly from a fast developing economy’s perspective, where an effective KM can further contribute to realising a reasonable level of competitiveness operation.

Risk management is a comparatively new field and there is no core system of risk management in the construction industries of developing countries. In Pakistan, construction is an extremely risk-seeking industry lacking a good reputation for handling risk. However, it is gradually giving it more importance as a result of increased competition and construction activities. For this purpose, a survey-based study has been conducted which aims to investigate the risk management practices used in construction projects in Pakistan. To achieve the objective, data was collected from 22 contractor firms working on 100 diverse projects. The analysis indicates that risk management has been implemented at a low level in the local environment. The results also disclose that there is a higher degree of correlation between effective risk management and project success. The findings reveal the importance of risk management techniques, their usage, implication, and the effect of these techniques on the success of construction projects from the contractor’s perspective, thus convincing the key participants of projects about the use of risk management.

Purpose The purpose of this paper is to construct a two-stage risk management framework for international construction projects based on the meta-network analysis (MNA) approach. A plethora of international construction studies seems to assume risks as independent and therefore, risk intervention strategies are usually critiqued as ineffective. Design/methodology/approach In the risk assessment stage, a multi-tiered risk network structure was developed with the project objectives, risk events, risk factors and stakeholders, and critical risk factors were selected based on a series of calculations. In the risk intervention stage, targeted risk intervention strategies were proposed for stakeholders based on the results of the first stage. A highway construction project in Eastern Europe was selected as a case study. Findings The results showed that 17 risk factors in three categories – external, stakeholder-related and internal – are critical, and the project manager, construction management department, supplier and contract department are the most critical stakeholders that affect the entire project performance. Based on the critical risk factors and project stakeholders, targeted risk intervention strategies were proposed. The risk assessment results of MNA were found to be more reliable and consistent with the project conditions than the risk matrix method; the risk intervention strategies of MNA can effectively address project objectives. Originality/value This study modeled risk priorities based on risk associations and put forward a new method for risk management, supplementing the body of knowledge of international construction. The results of this study are of critical importance in management practices.

. The use of bamboo as construction and raw material for producing products can be considered a feasible alternative to the abusive use of steel, concrete and oil byproducts. Its use can also reduce the pressure on the use of wood from native and planted forests. Although there are thousands of bamboo species spread about the world and Brazil itself has hundreds of native species, the use and basic knowledge of its characteristics and applications are still little known and little disseminated. This paper's main objective is to introduce the species, the management phases, the physical and mechanical characteristics and the experiences in using bamboo in design and civil construction as per the Bamboo Project implemented at UNESP, Bauru campus since 1994. The results are divided into: a) Field activities - description of the technological species of interest, production chain flows, types of preservative treatments and clump management practices for the development, adaptation and production of different species of culms; b) Lab experiments - physical and mechanical characterization of culms processed as laminated strips and as composite material (glue laminated bamboo – glubam); c) Uses in projects - experiences with natural bamboo and glubam in design, architecture and civil construction projects. In the final remarks, the study aims to demonstrate, through practical and laboratory results, the material's multi-functionality and the feasibility in using bamboo as a sustainable material.
