The purpose is to define a process model that will guide how such a continuous improvement system can be created in an organization utilizing takt production methods, and how the system can then be improved. This research follows design science approach to highlight the practicality of the solution. Research consists of diagnosis, process model creation, validation of the process model, discussion, and conclusion. Diagnosis is performed with a literature review and empirical research, including interviews and observations of current practices in a case company. Validation is performed by collecting external feedback and by organizing internal interviews. The findings indicate that the created process model provides a system that can be used to improve the takt production process with data, and that the process can be supported by also handling tacit knowledge. A defined learning system will help in tackling the current barriers facing the construction industry related to inefficient data processing and unclear knowledge management. As the system utilizes the terminology and theory of takt production, it is proposed that the system can be expanded to other projects and construction functions with further research.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116900061","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}

However, despite various attempts to evaluate LPS implementation efforts, the human aspect of the evaluation attempts has not been given enough attention. This issue may be tackled through Fuzzy Inference Systems (FIS) to capture more information regarding the gradual and intricate changes in scoring systems. Therefore, this paper aims to offer a standardized diagnosis model for LPS performance in construction projects. This model employs an FIS that analyzes the results of an LPS implementation for a more accurate investigation of the implementation. First, a thorough literature review is conducted to select the most prominent factors influencing the LPS implementation process, followed by expert panel questionnaire development and distribution among LPS experts to rank the selected factors. The obtained questionnaire results are then used to develop the FIS. The objective of this paper is hereby twofold: (1) to allow assessing expected LPS benefits through the qualitative assessment of the performance in the four LPS phases, and (2) to facilitate comparing past, current, and future performances throughout the organization's LPS implementation process to ensure continuous improvement. the factors factors model","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123654446","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}

As a result of this complexity, wastes and inefficiency occur within the internal and external supply chain. To improve productivity, companies are striving to implement Lean practices in ETO environments but encounter implementation barriers. Based on the comprehensive literature study on Lean implementation barriers in ETO companies, this study empirically validates the occurrence of these barriers in practice. For this purpose, empirical evidence was gathered using a survey questionnaire followed by semi-structured interviews with 15 companies from the ETO sector in construction, mechanical engineering, and shipbuilding. As a result, the barriers mentioned in the literature are compared with the barriers that occur in practice. Simultaneously, new barriers not described in the literature are also identified. This study can guide Lean professionals in the ETO environment in their Lean efforts to identify corresponding barriers in their own organizations while trying to understand the relevant causes and fields of action to mitigate them. Future research should aim to explore other methods and strategies along with emerging technologies of Industry 4.0 that could help overcome Lean implementation barriers.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125764911","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}

Productivity can be measured through time-motion studies but relies heavily on manual efforts and therefore contributes insufficiently to real-time awareness in dynamic environments such as construction. Indoor positioning shows potential determining shares of construction workers VA (Value-adding), based on Bluetooth Low Energy technology in real-time. Different studies show positive correlations between VA and productivity. However, it is unknown from location data how much workers engage in VA work while being present. Applying both methods simultaneously to one worker, this paper shows how to numerically quantify direct work (DW) and VA. Such combined data can show how much VA and DW occur when uninterrupted presence is detected while applying thresholds, indicating minimum durations spent inside work locations. Utilizing a small data sample enabled proof-of-concept testing and resulted in numerical quantifications of DW and VA. Preliminary findings show larger proportions of DW and VA when uninterrupted presence time is higher. Future research needs to enlarge the included data. If findings hold true, uninterrupted presence with higher thresholds could predict more accurate workers´ VA levels in real-time. The study also contributes to knowledge positively impacting construction by bridging workers’ behaviors on-site with monitoring technologies detecting movement.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128200278","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}

However, universities are often criticized for not developing essential, generic skills in their graduates, especially the ability to work collaboratively in teams. Attempting to better prepare students, academic institutions are creating vehicles to help their students acquire effective teamwork skills. Competitions, for example, have spread to almost every discipline, including the OAEC-related ones, since they have much to offer students of the built environment. The researchers assessed the participants’ experience of an interdisciplinary design competition to determine if such competitions are an effective means to impart teamwork skills to future collaborative stakeholders of the built environment. Additionally, this research aimed to identify areas where educators should prioritize their efforts to better prepare students for enhanced teamwork performance. In addition to highlighting that teams should be appropriately composed of members with critical, needed skill sets, results from a post-event survey of the case study competition also suggest there is a need to teach students how to develop clear and shared goals, develop clear and understandable roles, and communicate more effectively when working in teams.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127456278","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}

Impressively, this sector outpaces six of nine major industries in the country. However, their quantitative success may dampen Lean Construction's adoption, hurting the industry long-term. Practices significantly transform the value of the inputs, and contractors do it better than manufacturing. However, the industry is much riskier than manufacturing, so contractors hesitate to change to new ones quickly. It appears that organisations will not rapidly adopt Lean's methodology partially due to the success and risk of the Australian construction Industry. This paper proposes a survey methodology of practices to convince contractors of Lean Construction’s improvement potential. Obviously, they should search wherever there may be promising methods. However, this research outlines a straightforward process to validate valuable practices that can be executed internally in the industry and clarify practices' value and timely completion. The aim is to convince already superior performing contractors to see the LC approach as a competitive opportunity.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130130698","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 Integrated Project Delivery method (IPD) has the potential to solve these challenges. However, the existing IPD framework has a low feasibility rate in SMEs due to technological, financial, and managerial challenges. This is because IPD is a project delivery system that requires adequate capital, communication channels, software, training for workers, etc. which are usually available with large-scale construction projects but not with SME-based projects. Accordingly, this paper proposes a new IPD framework more specific to small and medium scale construction projects by improving the existing framework in terms of resource management and cross-validation of stakeholders. The proposed framework enables the SME projects to acquire and manage the resources for conducting IPD through the concept of “Multi-Project collaboration”. In the collaboration, multiple contractors with individual projects cooperate with one another for achieving a positive impact on their performance through the IPD method. This study contributes to the body of knowledge by enabling the construction industry to understand the effective application of the IPD method to SME projects.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123412450","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 project expansion and project support stages reached 162 sites within a year. This was split into three implementation cycles, led to training 40 multipliers in the lean philosophy and the last planner system within the company in question. The article also presents difficulties encountered in the process of implementing this high volume of sites.
