Empirical evidence shows that design-related challenges influence delay in building projects in India. Based on case studies of building projects from the capital region of Odisha Province of India, the factors relating to consultants and design have been identified and policy interventions were compiled to reduce design linked delay. A survey method to collect data, statistical analysis and a Systems Dynamics modelling approach were used according to different scenarios to propose strategic interventions. The findings suggested that complexity of design and compilation of documents, and the combined complexity of both can cause substantial delay. The model results revealed that the combined effect of appointing competent consultants and communicating effectively could reduce delay significantly. The novelty of the study lies in using a systems approach to develop causal feedback relationships among variables, as opposed to considering one origin of the problem at a time. The study makes three contributions: (1) design-linked challenges and mechanisms of delay, based on causal feedback relationships in building construction, can be diagnosed to evolve appropriate remedial measures; (2) impacts of different interventions can be visualised quantitatively under different scenarios; and (3) an alternative methodology to examine the trend of the project period is offered.

Environmental and ecological impacts associated with construction activities have become an ever-increasing concern, especially the considerable amount of waste generated on construction sites. Regulations and growing client pressure on meeting environmental standards have led contractors to adopt sustainable practices and try to embed this concept in their processes. Sustainable procurement management (SPM) as a potential solution takes the environmental consequences of procurement decisions into account and integrates sustainable practices into project procurement to bring positive environmental outcomes. Previous research has mainly focused on the public sector in achieving green procurement, yet this study attempts to highlight internal capacities that help private organisations manage the requirements associated with practicing sustainability. It is theorised that robust management structures, specifically project management offices (PMOs), would enhance the oversight capabilities of contractors in implementing the SPM process. The objectives of the current study are to (1) identify the requirements of a sustainable project procurement process in construction sites based on a literature review, and (2) explore the facilitative role of PMO units in achieving these requirements in the private sector. A literature review was conducted followed by a qualitative survey to solicit the viewpoints of construction professionals in principle contracting firms. As a result of the study, we identified 17 sustainability requirements and found that PMOs boost collaboration and improve the quality of decision making towards sustainable procurement. The findings (1) explain how PMOs support sustainability, (2) provide insights on implementing sustainable practices in project purchases, and (3) improve theoretical understanding of the SPM principles.

Many previous studies have reported that the occupational health and safety (OHS) enforcement is poor in developing countries, however these studies have mainly focused on the broader enforcement problems and not fully considered the challenges confronting the institutions responsible for enforcing OHS standards at workplaces. In this study, twelve potential challenges were identified from an extensive literature review, then an empirical investigation was carried out via a questionnaire survey from OHS inspectors and professionals in the Ghanaian construction industry. The twelve challenges were confirmed and ranked. Also, analysis of variance (ANOVA) and correlation were used to determine the statistical significance of the responses and the relationships between the challenges. Based on these findings, this study provides practical strategies for government, OHS inspectors and other professionals within the construction industry to improve the OHS enforcement. The research findings can also be adopted as a basis to assess challenges confronting OHS institutions in other developing countries.

A Delphi study using twenty-three project practitioners over six rounds is aimed to identify significant problems in project management, arising from the nature of projects other than those readily identifiable in a literature review. The study goes on to identify project managers’ behaviours which are recognised as having successful impacts on the delivery of projects. A Relative Importance Index for the problems and behaviours resulting from the issues identified in the study is calculated. This study continues by reporting the views of practitioners involved in the management of large projects on the everyday problems they experience in managing projects, problems that are not adequately addressed in current project management texts concerning the nature of projects. Five additional problems, not generally discussed in the literature, were identified together with seven interpersonal skills and behaviours that are major contributors to increasing the likelihood of a successful project delivery.

The urban public housing project, especially for low-income people, is essential to cater to the increasing urbanisation rate in Malaysia. This study aimed to gain an understanding of the project governance practices in urban public housing projects in Malaysia, which will lead to better project delivery and the successful outcome of the projects. A single case study was conducted on a public housing project or known as Projek Perumahan Rakyat (PPR) in Kuala Lumpur, and data for this study was gathered using semi-structured interviews with six (6) public officials, document analysis, and observation. The findings of this study indicate the positive interplay between project actors guided by the elements of trust, stakeholder management, empowerment, and collective decision making, which create value for the project. Hence, this article contributes to the dynamic understanding of how public officials practice project governance in conducting their works related to urban public housing projects. The findings of the study will enable related public organisations to reinforce the underlying project governance elements towards the strengthening of urban public housing delivery DECLARATION OF CONFLICTING INTEREST The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article. FUNDING The author(s) received no financial support for the research, authorship, and/or publication of this article. 120 system. Case study research in different models of urban public housing could extend the discovery of other project governance elements while validating the findings of this study from different perspectives. The findings of the study are limited due to the use of a single case study related to the urban public housing project and its contexts.

With constant flow of large data sets generated by different organisations, big data analytics promises to be a revolutionary game changer for Architecture, Engineering and Construction (AEC) industry. Despite the potential of Big Data, there has been little research conducted thus far to understand the Big Data phenomenon, specifically in the AEC industry. The objective of this research therefore is to understand the contributing factors for adopting big data in AEC firms. The investigation combined the perceived strategic value of BDA with the TOE framework (technology, organization, and environment), to develop and test a holistic model on big data adoption. A set of hypotheses derived from the extant literature was tested on data from structured surveys of about 365 firms, categorised as construction service firms (engineering and architecture) and construction firms (firms engaged in managing construction projects). The results indicated that the inhibitors and facilitators of BDA adoption are different in the construction services (architecture and engineering) and construction firms. For effective adoption of BDA solutions, the findings will guide the business managers to have realistic expectations of BDA integration challenges in AEC sector.

Over many decades, buildings have been recognised as a significant area contributing to the negative impacts on the environment over their lifecycle, accelerating climate change. In return, climate change also impacts on buildings with extreme heatwaves occurring more frequently and raising the earth’s temperature. The operation phase is the most extended period over a building’s lifespan. In this period, office buildings consume most energy and emit the highest amount of greenhouse gas pollution into the environment. Building upgrading to improve energy efficiency seems to be the best way to cut pollution as the existing building stock is massive. The paper presents an economic analysis of energy efficiency upgrade of buildings with a focus of office buildings. The paper identifies upgrading activities that are commonly undertaken to upgrade energy efficiency of office buildings and a case study of three office buildings in Sydney, Australia has been used to analyse the results. The upgrading activities can improve the energy performance of the case study buildings from 3 stars to 5 stars NABERS energy rating in compliance with the mandatory requirement in the Australian government’s energy policy. With the potential increase in energy price, energy efficiency upgrading will become more affordable, but currently, most of them, except solar panels and motion sensors show a negative return and would not be undertaken if they did not also contribute to higher rental income and an increased life span of the building.

The question of how successful a project is beyond the handover stage is still echoing in the literature on project management and more magnified in international development (ID) projects. In addressing the question, this study aims to demonstrate the importance of time frame in assessing project success, particularly identifying the success criteria at the posthandover stages (outcome and impact stages). This study used a qualitative approach that was rooted in interpretivism, allowing the use of constructivist grounded theory method (CGTM) in an ID project as an example. The study identified eight success criteria: Convenience, Development, Documentation, Maintainability, New Capability, Price of Service or Product, Training, and Usability. The study also found that, first, each participant had different emphases on different success criteria; second, most of the identified success criteria were still under the outcome stage; and lastly, usability received the highest responses from the participants as the most concerned criterion at the post-handover stages. This last finding verified the importance of time frame where the other criteria became less important if the outputs were useful to deliver the institutions’ strategic objectives. Future studies that use more sampled participants and different types of institutions are also encouraged.

Within the highly waste-generative context of Australia, waste from demolition of office fit-out significantly contributes to unsustainable landfilling. The extant literature is, however, slim on scrutiny of the situation. Therefore, this study aims to uncover office fit-out demolition processes and product features that drive high ratio of landfilling fit-out elements. The research used ten case projects and fourteen interviews to document visible and latent parameters of office fit-out waste. Waste-stream mapping and decision-tree techniques, in conjunction with basic descriptive statistics, were used to model and visualize the extent and drivers of unsustainable fit-out demolition. Further, an exemplar product features analysis was conducted to validate the identified drivers. The findings show that 78% of fit-out waste from the studied cases is landfilled. This high rate is attributed to both latent and visible factors. The main latent factor is high lease price of premium or high-quality offices which favours expeditious demolition with low consideration for reuse and recycling. Key technically visible barriers are volumetric furniture, heterogeneous fit-out assemblies, and insufficient critical mass. To move away from landfilling, production of office fit-out should be transformed for sustainable material adequacy, product re-configurability and de-constructability, and easy handling in the use phase.

The literature on megaprojects are oriented towards ‘knowing’ the problems and ‘knowing’ the solutions, and there is a dearth in literature aimed at explaining strategies adopted in ‘doing’ or implementing that knowledge. Particularly, the literature highlights communication as important as part of the ‘knowing,’ while there is a gap in ‘doing,’ as performance improvements are still not evident. This research aims to explore how this knowing-doing gap in the communication of risk information was addressed by using 4D visualization. This article discusses the vent facility of a megaproject in Australia as a case study to illustrate the innovation. The 4D model developed for the facility helped the project team to visualize the construction of a critical part of the project, discuss the construction methodology, identify the risks in the construction process and persuade the non-technical decision-makers of the project to take appropriate action. The risks identified through the visualization covered safety, program, and interface risks. This study offers insights into the role of visualization in bridging the knowing-doing gap in the construction industry in the context of a megaproject.
{"title":"4D visualization to bridge the knowing-doing gap in megaprojects: an Australian case study","authors":"Abhijnan Datta, Johan Ninan, S. Sankaran","doi":"10.5130/ajceb.v20i4.7015","DOIUrl":"https://doi.org/10.5130/ajceb.v20i4.7015","url":null,"abstract":"The literature on megaprojects are oriented towards ‘knowing’ the problems and ‘knowing’ the solutions, and there is a dearth in literature aimed at explaining strategies adopted in ‘doing’ or implementing that knowledge. Particularly, the literature highlights communication as important as part of the ‘knowing,’ while there is a gap in ‘doing,’ as performance improvements are still not evident. This research aims to explore how this knowing-doing gap in the communication of risk information was addressed by using 4D visualization. This article discusses the vent facility of a megaproject in Australia as a case study to illustrate the innovation. The 4D model developed for the facility helped the project team to visualize the construction of a critical part of the project, discuss the construction methodology, identify the risks in the construction process and persuade the non-technical decision-makers of the project to take appropriate action.
