{"title":"Enablers for facilitating life cycle assessment: key stakeholder perspectives of Sri Lankan construction industry","authors":"I. Amarasinghe, C. Hadiwattege","doi":"10.1108/bepam-02-2021-0033","DOIUrl":"https://doi.org/10.1108/bepam-02-2021-0033","url":null,"abstract":"PurposeDespite the desire to improve the sustainability of the construction industry, Sri Lanka is still plagued by the low-level adoption of essential methods such as Life Cycle Assessment (LCA) in building and infrastructure delivery. It is indispensable to investigate enablers for facilitating LCA because identification of enablers is a crucial step in the implementation of LCA. This study aims to analyze internal and external enablers for facilitating LCA for the Sri Lankan construction industry from the perspective of five stakeholder categories (academia, government, construction industry, society and environmentalists) and also aims to develop strategies to strengthen the enablers.Design/methodology/approachAn explanatory research design was used. The five stakeholder categories identified above, whose contribution is essential for implementing LCA in Sri Lanka, were selected for data collection. A total of 20 semi-structured interviews were held representing each stakeholder category. The Repertory Grid Interview (RGI) technique was utilized and data analysis was performed using content analysis.FindingsThe results revealed that “ability to identify opportunities for environmental improvements as an extremely important internal enabler for all stakeholder categories” and “the positive growth in the country to achieve environmental sustainability”, “the availability of standardized LCA guides and handbooks” as extremely important external enablers for all stakeholder categories for facilitating LCA in the Sri Lankan construction industry. Further, strategies including making people aware of the LCA concept and development of the LCA database, etc. were proposed to strengthen the enablers.Practical implicationsKnowledge generated through this study would enable the abovementioned stakeholders to make informed decisions to promote the implementation of LCA in the Sri Lankan construction industry. Further, the results of this study have raised awareness of the issues that Sri Lanka will need to solve to expand the LCA applications.Originality/valueSo far, research on LCA has not looked into enablers that can facilitate the implementation of LCA in the Sri Lankan construction industry. This research provides a comprehensive view of the internal and external enablers for facilitating LCA from the perspective of five stakeholder categories and identifies enablers that led the abovementioned stakeholders to pursue the implementation of LCA in the Sri Lankan construction industry. The study also proposes strategies for strengthening the enablers.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49292488","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}

The LEED v4 scoring system for New Construction and Renovation was adopted for the survey questionnaire on five point Likert scale. Data were analyzed using the MIS and Kruskal–Wallis Rank sum Test.FindingsAwareness of the LEED requirements varies across the categories. Sustainable site is ranked first while innovation and regional priority ranked from the rear. There is variation in awareness among the professionals. The Land Surveyors are followed by the Architects while the Builders ranked last.Research limitations/implicationsThe scope of the study is limited to the professionals in the PPUs in the study area. However, the findings are indicative. The low level of awareness of some of the requirements and the extent of variation among the professionals will negatively impact the integrated design approach and collaborative effort needed for green housing to meet the housing deficit in Nigeria.Practical implicationsThe study is limited in scope. The low level of awareness of the requirements coupled with the extent of variation among the professionals will negatively impact the integrated design approach and collaborative effort needed for green housing to meet the huge housing deficit in Nigeria.Originality/valueThe study takes the lead to assess the awareness of the requirements for green housing development based on the LEED impact categories. Improving the awareness of these requirements will enhance their implementation and consequently impact the quality of housing provision.

It examines major SUSIs under the social, economic and environmental (SEE) fronts and categorizes them under push and pull impacts which helps to identify challenges and opportunities associated with projects. Additionally, the study calculates an empirical sustainability index (SI) to assess the sustainability level of HEP. Finally, the study suggests mitigation measures across stakeholders, which will optimize government/developer/investor investments.Design/methodology/approachThis paper examines the interaction of sustainable HEP development with SUSIs using Uttarakhand as a study area. Additionally, SI has been developed quantitatively. For the indicator classification, the authors conducted a literature review and secondary survey of all affected parties, including investors, developers, NGOs and villagers. The fuzzy logic theory (FLT) is used to determine the SI of the study area and classify projects in their level of sustainability. On the basis of expert opinion and literature review, mitigation measures are proposed across stakeholders.FindingsThe authors found that there is a mixed effect of SUSIs on HEP development across various projects in Uttarakhand. Furthermore, the authors suggest that index-based assessment and planned collaboration play a significant role in sustainable HEP development. Mitigation measures should be suggested to all affected stakeholders based on specific project issues, i.e. collaborations, training, public awareness campaigns, and initiatives by the government that would improve sustainability conditions.Research limitations/implicationsIn addition to supporting the ongoing and upcoming initiatives launched by the Government of India, including the Green Energy Corridor, independent power producers (IPPs); and the India-Renewable Resources Development Project with IDA and participates in Net zero target.Practical implicationsThe structured, sustainable HEP planning suggested in the study will help to conserve society, economy, save resources and in parallel reduce the cost and time of developers and policymakers. This will also help to improve the socioeconomic status of the villagers and prolong the life of the project.Originality/valueThe innovative SI-based push-pull approach identifies a sustainable HEP project planning.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49031463","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}

The quest for a lasting solution to these problems is heralding the change toward offsite construction. Amid the scaling drive, to date there are no official reports and contribution to knowledge on the drivers of offsite construction in Ghana. This study models the structural paths of the critical drivers of offsite construction in Ghana.Design/methodology/approachData were collected through a questionnaire from 95 respondents in the Ghanaian construction industry. Exploratory factor analysis and Partial least squares structural equation modeling were employed to analyze the data.FindingsThe results revealed that industry dynamics are the governing drivers of offsite construction in Ghana. As such, factors such as the rocketing housing deficits, high cost of acquiring land permanently, high cost of cast-in-situ construction, the utilization of prefabricated shipping containers for construction and construction market demand constitute the governing drivers of offsite construction in Ghana. Similarly, concern for higher productivity is a critical driver of offsite construction in the Ghanaian construction industry. On the contrary, findings show that performance-related drivers, government policy and regulation, and technological innovation exert little influence in driving offsite construction in Ghana.Practical implicationsThe appreciation of the drivers may help stakeholders to understand the important mechanisms underlying offsite construction in Ghana, and thereafter help them to make more informed decisions regarding its implementation.Originality/valueThe findings contribute some interesting dimensions to the global debate on offsite construction by discovering and adding two drivers of offsite construction peculiar to developing countries (high cost of acquiring land permanently, and the utilization of shipping containers for construction) to the literature.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48132059","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}

Members of a virtual team are geographically scattered and represent a diverse range of cultures. Thus, challenging issues emerge more frequently than in a traditional team. There are challenges associated with space and time as well as high client's demand. Therefore, this study aims to identify and probe the causes of the challenges in virtual project teams in the construction industry of the Middle East.Design/methodology/approachA list of challenges was derived through a comprehensive review of relevant literature. Questionnaire survey was conducted with professionals who are involved in construction virtual project teams. Further, the factor analysis technique was used to analyse the survey responses.FindingsThe results show that the challenges in virtual team arrangement in the Middle East construction industry can be grouped into seven categories, namely, organisational culture, conflict within the team, characteristics of the team members, trust within the team members diversity of the team, communication and training, and cohesion in the team. Understanding of these factors will drive the needed platform to support effective virtual project teams in the Middle East.Originality/valueThis study raises the prospect that organisations may establish an environment for team members to achieve higher levels of virtual cooperation by concentrating on these potentially crucial factors. This, in turn, will encourage further innovation and performance within construction organisations.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41644889","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}

The primary research question that is addressed is “How to quantify the performance improvement in automated construction processes?”Design/methodology/approachA systematic literature review of papers on automated construction was conducted involving three stages-planning, conducting and reporting. In the planning stage, the purpose of the review is established through key research questions. Then, a four-step process is employed consisting of identification, screening, shortlisting and inclusion of papers. For reporting, observations were critically analysed and categorized according to themes.FindingsThe primary conclusion from this study is that the effectiveness of construction processes can only be benchmarked using realistic simulations. Simulations help to pinpoint the root causes of success or failure of projects that are either already completed or under execution. In automated construction, there are many complex interactions between humans and machines; therefore, detailed simulation models are needed for accurate predictions. One key requirement for simulation is the calibration of the models using real data from construction sites.Research limitations/implicationsThis study is based on a review of 169 papers from a database of peer-reviewed journals, within a time span of 50 years.Originality/valueGap in research in the area of performance evaluation of automated construction is brought out.

Consequently, virtual FAT (vFAT) became a popular substitute for physical FAT. However, the credibility of vFAT is being questioned because it was adopted without much scrutiny. Hence, this study is aimed at investigating vFATs and re-engineering the FAT process to suit an effective vFAT environment.Design/methodology/approach A comprehensive literature search on FAT procedures was followed by two stages of expert interviews with eight leading subject experts and a case study. The findings were analysed using code-based content analysis on NVivo software.Findings Strengths of vFATs include “reduction in cost and time consumed”, “flexibility for more participants” and “faster orders”. Most emphasized weaknesses include “lack of reliability” and “lack of technology transfer”. vFAT has mostly increased test reliability by “improving accessibility” and has decreased reliability by “restricting physical touch and feel observation of the equipment”. A four-step vFAT process was developed with a noteworthy additional step called “Pre-FAT Meeting”.Research limitations/implications The scope of this study is limited to the Sri Lankan construction industry. Expansion of the geographical area of focus is recommended for future studies.Originality/value The findings of this study unveil a vFAT process, which is timely and beneficial for construction practitioners to optimize and enhance the effectiveness of vFATs which are currently conducted in a disarranged manner.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44260998","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}

The data collection process involved meeting the students face-to-face and demonstrating the VR model to them, after which the students completed an online questionnaire and assessed design buildability using both 2D drawing and virtual reality (VR) models. To make this assessment, the participants considered a residential earth building modelled to promote sustainable building features. The assessment process required the participants to evaluate the design buildability of the same building design using a 2D drawing and a 3D VR model.FindingsThe study found that VR models have significant advantages for assessing design buildability. Students measured 16.80% higher average buildability with the 3D VR model compared to the 2D drawing. The participants in the evaluation felt that the visual model significantly improved the comprehensibility of complex designs, which helped identify and manage design buildability (overall, 83% of participants strongly supported this).Originality/valueThe paper showed construction digitisation such as VR, augmented reality and building information modelling is highly cooperative as it can easily be made available for online learning.
