The need for sustainable practices in megaproject implementation is becoming acute. With the ongoing progress and expansion of mega infrastructure projects (MIPs), a lot of attention has been attracted among policymakers and researchers due to their enormous impacts on the economy, society, and the environment. Given the complexity of MIPs and the sustainability-related challenges it faces; the successful management of sustainability-related targets requires influence from the institutional forces (regulative, normative and cultural-cognitive). However, existing research on the institutional drivers that can effectively promote the sustainability of megaprojects has been largely unexplored and calls for attention. Therefore, this study aims to present a review of what drives the adoption of sustainable practices in MIPs. A systematic literature review was conducted based on a combination of keyword search in the Scopus database. Using the lens of institutional theory and deductive approach, 11 drivers for sustainability in MIPs were identified from reviewing 33 selected peer-reviewed articles. This study would enhance project stakeholders’ and policymakers’ understanding of drivers for sustainability and help further improve policies, strategies, norms and culture to support MIPs in contributing to sustainable development goals.

Negotiations are required in every stage of a construction project. The process of negotiation involves being able to understand the position and emotions of the other side of the negotiation. A reliable means for understanding cultural basic assumptions on negotiation tactics assist in better predicting how individuals may act in a negotiation. This research aims to analyse the effect of basic assumptions of consultants and contractors on negotiations in the South Australian construction industry. This was approached through a case study research strategy, utilising semi-structured interviews with two contractors and two consultants each from three large South Australian Road projects followed by a Content Analysis. Findings reveal that both the contractors and consultants believe the nature of human relationships as collaborative and therefore view negotiations as a mean of strengthening the partnership. They negotiate openly to reach win-win outcomes. They view the nature of human nature to be good, therefore more trust and more openness to creative new ideas in negotiation planning. Respondents mostly believe the nature of the human activity to be harmonizing and are more likely to use trade-offs in reaching mutually beneficial negotiation outcomes. The knowledge created in this research will be useful for anyone preparing to negotiate within the South Australian construction industry or similar cultural setups to understand and predict how contractors and consultants would react to different situations and issues within negotiation processes and to achieve effective outcomes. Further research can study the basic assumptions of sub-contractors about negotiations.

The construction industry is a major economic driver in Sri Lanka. However, the construction industry was significantly affected by the responses made by the Sri Lankan government to prevent the spread of the COVID-19 pandemic. The effects of those government responses on construction projects are diverse as time, cost, and qualityrelated impacts. These effects resulted in numerous contractual effects that were mostly to be dealt with reference to the provisions made in the standard forms of contracts such as ICTAD/SBD/02 and FIDIC 1999 in Sri Lanka. Since no similar pandemic has affected Sri Lanka at this magnitude before, neither ICTAD/SBD/02 nor FIDIC 1999 have been drafted giving due consideration to such exceptional circumstances. Furthermore, no studies that researched these kinds of aspects can be found in the existing literature. Hence, this research aims to explore the effects of the responses made by the Sri Lankan government to prevent the spread of the COVID-19 pandemic on the construction industry and the possible adaptations of standard forms of contracts to address the contractual implications of those effects to mitigate the effects on the contractual parties in both building and civil engineering projects. A desk review was carried out to identify the existing provisions of ICTAD/SBD/02 and FIDIC 1999 to overcome the effects of pandemic situations, and three case studies, including two building projects and one civil engineering project, were used for the empirical data collection. Representing contractors, consultants, and employers, twelve semi-structured interviews were conducted within the three case studies. The research findings reveal that a collaborative approach with cost and time-sharing is the best approach to address the effects of a pandemic situation. Furthermore, defining terminologies, developing transparency in contractual relationships, and establishing an equal assessment basis can all aid in the contractual development of the ICTAD/SBD/02. As a result, the study suggests improving documentation practices, developing guidelines for amicable settlement, and eliminating the adversarial effects of ICTAD/SBD/02 through an equal assessment process. Thus, this research contributes to the further development of ICTAD/SBD/02 while also improving Sri Lankan building and civil engineering projects by reducing contractual issues in future pandemics.

The accuracy of computer vision-based progress monitoring of construction projects depends on the quality of data acquired. The data acquisition can be conducted through different vision-based sensors combined with several options for sensor mounting. Several factors affect this combination and considering these factors in selecting the acquisition technology and sensor mounting combination is critical for acquiring accurate vision-based data for the project. Currently, their definition and impact of these factors on the selection of these technologies are both subjective, and there are no formal studies to evaluate the impact. Hence, in this study, we first identify and define twelve key factors affecting data acquisition technology and eight factors affecting sensor mounting. Next, a questionnaire survey was designed, and responses from professionals were used to evaluate the Relative Importance Index (RII) for the individual factors for these technologies and methods. The obtained ratings were compared to the author's initial assessment, and the cause for a few variations obtained was justified. This study provides a clear assessment of these factors and forms a basis for selection based on the factors involved with the project requirements.

The building construction industry is globally identified as one of the major consumers of materials. Thus, the material wastage in building construction projects is very excessive. In the Sri Lankan construction industry, it was identified that the main reason for generating material wastage is the absence of proper material selection criteria. The concept of Circular Economy (CE) has been obtained the world attention in reducing material wastage in the construction industry as it targets zero waste and pollution throughout the lifecycle of materials. Applying CE principles in the material selection not only reduces the wastage of materials but also reduces the use of virgin materials. Hence, this research aimed for developing a CE-based 10R evaluation framework for materials selection in order to reduce the wastage of materials in building construction projects in Sri Lanka. A comprehensive literature review was first conducted to review the concept of CE, CE principles and its importance for reducing material wastage in the construction industry. Deductive approach was chosen as the suitable research approach in this study. Survey method was applied as the suitable research strategy under quantitative phenomenon. A questionnaire survey was conducted with a conveniently selected sample of 58 industry professionals to collect the data. The collected data were analysed by using Weighted Mean Average (WMA) technique. As key findings derived through analysis, the level of importance of each CE principle for selection of materials was determined. Accordingly, the CE-based 10R evaluation framework for material selection was developed as the main implication of this research. Various strategies, such as reusing demolition materials, adopting prefabricated building components, developing plans to on-site recycle and using alternative materials were also proposed to implement the all identified CE principles assuring a successful application of the developed framework.

Risk management is an essential process for the successful execution of the project, and it is pertinent in achieving the project objectives and leading to its successful outcome. The nature of the construction industry, which is full of uncertainty and high capital investment, makes it notably more critical to address and manage the risks promptly. The most important part of the risk management process is identifying and assessing risks. However, the traditional Probability (P)-Impact (I) matrix used in their evaluation fails to account for the uncertainties witnessed in the determination of both P and I. This paper, therefore, uses a fuzzy approach to develop a risk assessment model. Further, the results of the generated model are compared with the conventional P-I matrix to show the effectiveness of the adopted fuzzy system. The data for the model development was collected from one of the metro-rail projects through a questionnaire. Subsequently, semi-structured interviews were conducted to identify the advantages of BIM in the project. The recognized BIM advantages were then correlated with the critical project risks to present it as the process for mitigating these risks. The study findings present the use of FIS to overcome the uncertainty in the risk management process, followed by the applicability of BIM as a risk mitigation tool. Establishing the role of BIM in the risk mitigation process can help in its wider acceptance in the construction industry.
