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.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2021-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48389490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2021-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48081625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"49 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89653373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.

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.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":"7 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2020-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86385310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
