There is a growing body of research related to the circularity of specific construction materials, as well as to the entire building. However, there remains a lack of understanding at the construction product level, and this lack of transparency prevents informed decisions when choosing which products to use in projects and how those products support the CE. A maturity assessment is one methodology that can provide insights for both product decisionmakers and product suppliers. Maturity assessments are a way to evaluate the level of development or progress towards a certain goal, whether at the organization, project, or product level. This paper proposes a conceptual framework to assess construction product system circularity maturity. Through a systematic literature review, the authors analyze existing CE maturity assessments and CE indicators for construction products to develop the framework. The functional unit is defined as a construction product, which is defined as an integrated system with multiple materials (i.e. a prefabricated wall system). This research finds that while there are many CE assessment frameworks for the construction sector, these must be translated into a construction product context, which requires a tailored subset of circularity indicators and maturity levels. The paper proposes construction product maturity levels ranging from “initial” to “optimizing” for key circularity indicators at the construction product level, including, material procurement, manufacturing, product use phase, and end-of-life. This conceptual framework serves as a practical tool for decisionmakers and as an educational tool for suppliers on how to support the CE in construction.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200529","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}

Innovative building concepts on a neighbourhood scale present promising potential to revolutionise how buildings can be designed, built and operated in different climate zones that can bring about a significant decarbonization in the built environment. However, this potential can only be unleashed if a broad range of knowledge and understandings – both technical and non-technical – can be skilfully combined. Yet, such projects are often confronted with a transdisciplinary challenge that is inevitable and inherent. This paper characterises the transdisciplinary challenge in the development of four proofs-of-concept of Sustainable Plus Energy Neighbourhoods (SPENs) in four European countries. It adopts the qualitative research method capturing emerging innovations as practices to position the empirical lens close to what actors do to address the transdisciplinary challenge. The contribution of this paper is to better understand the transdisciplinary challenge that can slow down the uptake of the SPEN concept in the built environment. The paper ends with some suggestions for overcoming the transdisciplinary challenge in the development of neighbourhood scale building projects to unlock its positive effects.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200553","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}

Machine Learning techniques could discover latent hazards and risks by utilizing project-specific safety-related data and improve safety and decision-making processes. Findings suggest that machine learning can significantly improve safety performance by proactively identifying risks and measures from safety-related data rather than relying solely on historical safety outcomes and data. This could also provide a better understanding of the forthcoming construction projects’ complex challenges and the impact of increasingly technical and organizational complexities on safety. However, challenges such as data compatibility, lack of standardization, misinformation risks, and ethical concerns (transparency, privacy, and fairness) necessitate a cautious approach to the use of machine learning. This proactive approach could lead to safer construction environments and continuous improvements in safety management. Future work will refine data collection and develop predictive models, with the current research in the ‘DiSCo’ project aiming for sustainable safety improvements in the construction industry.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225670","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 private sector procurement, evaluation of past performance is natural part of the evaluation process procurement. In public procurement there are more limited possibilities to evaluate past performance based on the rules and regulations that need be adhered. During 2020-2022 the Swedish National Transport Administration conducted 30 procurement pilots where they used past results from a performance assessing tool as award criterion in the evaluation of tenders. The purpose of the research presented here is to gain knowledge of how past performance can be used an award criteria within the boundaries of the EU public procurement directive. More specifically, can a evaluations from tool developed for assessing supplier performance during a project implementation, be used as an award criterion in the procurement of forthcoming projects. Ever since the ruling from Court of Justice of the European Union (CJEU) in the Lianakis case C-532/06, experts and courts have argued about where the limit is for allowing evaluation of suppliers past performance. A nuanced interpretation is that evaluation of past performance is allowed if the evaluation is focused on factors that gives an added value in identifying the best bid and not only evaluates the supplier’s general ability. The result of this study showed that is possible from both a legal as well as a procurement process perspective to evaluate past performance in public procurement. However, the system used needs to design in a way that is clear and non-ambiguous. Further, there is a challenge of how to assess new suppliers in a market where there is no past performance to evaluate. There are ways of doing this but needs to be done within the boundaries of public procurement principles set by the EU directives.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200623","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}

Generative AI has surpassed human capabilities in various tasks, offering a unique opportunity to address longstanding development barriers in construction management. Previous research has shown how generative AI can help with individual management tasks but a wider overview of how generative AI could help in construction management is still missing. By breaking down construction management into individual tasks and linking each task to available generative AI solutions, the study uncovers multiple innovative approaches to enhance current practices. Consequently, this research introduces the mapping of management tasks and explores a range of practical implications of generative AI on construction management. The research takes a mixed-methods approach, collaborating with industry professionals from Finnish construction companies through focus group discussions (FGD), and questionnaires to gather valuable feedback. The outcome is a pragmatic summary of seven management actions, connected with generative AI solutions, and their quantitative potentiality assessment. The results indicate an overall good potential for integrating generative AI into construction management, with AI-enhanced chair and secretary actions, communication and situational awareness, data analysis and improvement, and risk management receiving the highest perceived potentiality scores.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200628","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 Norwegian Olympic and Paralympic Committee and Confederation of Sports (NIF) aim to take responsibility for the environment while planning, designing, constructing, operating, and maintaining sports facilities. There will always be dilemmas between the three dimensions of sustainability in decision-making processes. This research aims to illustrate different dilemmas and show how they should be dealt with when planning new sports facilities. This will help doing more informed decisions. The main objective of new sports facilities is to create activity, which creates value for users and the society. We have, through some examples, showed some dilemmas between sustainability’s social, economic, and environmental dimensions. A dilemma is how to plan, design, and construct more environmentally friendly facilities that still support the increased activity within a limited amount of funding. The “Sustainability Check” is presented as a tool, where the impact from the sports facility on the UN’s 17 sustainability goals is evaluated. But it lacks a way of weighting the different criteria. A further development suggested is to integrate the “Sustainabililty Check” with a multi-criteria decision-making method like Choosing by Advantages. More research is needed to test this integration.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200523","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 Italy and many European countries seismic structural safety standards requirements are also increasing, and therefore together with other renovation works, a structural rehabilitation is always needed. Structural rehabilitation is generally an invasive intervention on the structural sub-system, while energy redevelopment is less invasive as it is mostly performed in the building envelope, but it is economically relevant. Therefore, the high renovation costs and the limitation of the usability of the building during a renovation project often lead real estate developers to choose the easier strategy of complete demolition and reconstruction. This can be, perhaps, the easiest choice but, from an environmental and economic point of view, usually the least sustainable one. Environmental sustainability can be evaluated via the Life Cycle Assessment (LCA) approach, but LCA needs a complete evaluation of the existing and new building systems, sub-systems and components. Therefore, the strategic choice based upon LCA can usually be performed only late in the design process, when most of the technologic systems have been designed in detail. A parametric preliminary evaluation can help project managers and real estate developers to choose the most environmentally sustainable design alternative, even with a low level of knowledge of the existing building. The proposed approach uses a list of parametric costs for a building type to extract preliminary data about building quantities. Therefore, a mixed method that uses typical cost plans and existing LCA database is proposed to perform the preliminary LCA analysis of a building renovation project and evaluate sustainability.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200557","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 increased focus on sustainability has impacted both the project management (PM) and facilities management (FM) activities. This sustainability challenge is a complex and important to deal with. The role of sustainable PM in FM is significant towards achieving sustainable development as projects are the means of implementing sustainability strategies that are targeting the 3 P’s (people, planet, and profit) of sustainability. The novelty of this paper is in its focus, with a combined focus on both the Architecture, Engineering and Construction (AEC) and FM industries using PM as a focus while investigating sustainability drivers that can help the industries overcome complex and challenging sustainability barriers. We as part of the paper aim to develop a sustainability drivers’ framework that can guide researchers and practitioners in PM and FM to tackle sustainability challenges. By performing a literature review using the ScienceDirect and Google Scholar databases, 74 articles were finally selected to highlight the key sustainability drivers. Based on the collected literature, a theoretical sustainability drivers’ framework was produced that can help in advancing the FM via the sustainable PM. The resulting sustainability drivers were categorised as (1) organisational aspects, (2) financial factors, (3) promoting awareness, (4) stakeholders’ role, (5) standards and tools, (6) government policies and regulations, and (7) others. In this paper, we focus on two categories in detail from a project governance (PG) perspective, that is, organisational aspects and stakeholders’ role. The main takeaway of our study is the theoretical sustainability drivers’ framework that will guide the practitioners and researchers in AEC/FM industry to deal with the complexity brought by sustainability challenges through the sustainable PM lens, and become a powerful driver of long-term value creation for their organisations by effectively applying sustainability practices.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200569","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}

A number of studies show that leadership engagement in construction projects influence safety, however, the importance of how the client management role is carried out with regards to physical presence over time during construction has not been in focus. The aim of the study is to understand how safety is influenced by the presence of client personnel on construction sites related to renewable energy and the effects of their presence. Insights from both the client and contractor perspectives are provided, based on eighteen semi-structured interviews. The results show that degree of presence is determined by the project managers in early stages of the projects and this decision is based on factors such as economy risk assessment, knowledge transfer and projects size and complexity. Three main factors that stem from client’s presence are found to influence safety; i) increased monitoring which leads to higher risk awareness, ii) increased local knowledge which leads to identifying valuable solutions to issues and iii) shorter communication paths reduce uncertainty and positively impacts progress. Identified challenges regarding client’s presence are related to over-involvement and becoming blind to hazards. In conclusion, the client personnel’s onsite presence is important for creating a shared understating between client and contractor of safety issues, something that is not possible through remote collaboration, and especially important when projects increase in complexity.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200598","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}
