Effective control is of utmost importance for takt production, which is especially vulnerable when disruptions occur. While previous takt production research has primarily focused on how to form a good takt plan, little attention has been given to how to control and continuously improve takt production systems effectively. Addressing the gap, this study inspects takt control through the lenses of failure modes and effects analysis (FMEA). First, we argue that takt control can be perceived through three different failure categories: failures within wagons, failures in handoffs, and failures in takt trains. We discuss the peculiarities of takt control through these categories and provide examples of failures with their respective failure mode(s) and possible control action(s). Second, we construct an FMEA-based framework for effective takt control that shows how to recover from failures and avoid them altogether. Future research may consider validating the failure categories and the framework through case studies or simulations, and examining their applicability in supporting digital takt production.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"6 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":"124833954","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, what is rarely discussed is how the LOB should be applied in projects already in progress. This research was developed in the Design Science Research (DSR) format and sought to analyze how LOB can bring about significant changes in the management of collaboration, planning and production. This paper puts forward a collaborative method of training on LOB in projects that are already in progress for which it draws on a two case studies on multifamily residential building. The benefits of LOB for those involved in the workshop were collected by gathering multiple pieces of evidence and analyzing the correlations. In the participants' perception, there are three main benefits concerning to adopting LOB: (i) understanding the sequencing of activities and how to achieve the uninterrupted flow of teams; (ii) assessing the risk of mobilization and remobilization; (iii) assessing milestone dates and constraints. Moreover, participants´ perception, the training had a excellent evaluation, and it contributed to increasing their collaboration and engagement in relation to the planning of the project.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"40 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":"133512572","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, there is limited evidence of lean percolating through organisations in both literature, as well as industry. While the critical aspects of strategic adoption of lean to overcome organisational resistance have been clearly highlighted, the implementation is in most cases limited to select projects and not all projects across an organisation’s portfolio. Despite proven benefits on projects within their own portfolio and the knowledge and skills for successfully implementing lean, organisations still fail to change their approach towards continuous improvement and driving efficiency as a whole. The paper here focuses on the need for a revised approach towards the adoption and sustenance of lean within companies at a business level by highlighting the importance of culture across the company’s portfolio. The authors reflect on their experience of working with client and contractor organisations across multiple projects to review the difference in the maturity and implementation of lean. Following this, the authors corroborate their findings from discussion with a major public sector body and its supply chain on their lean journey over the last decade, to shed light on the approach needed today for successful lean implementation for organisation-wide sustenance.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"44 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":"115389782","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}

One of the main principles, collaboration, has previously taken place through co-location of the various actors that take part in the design phase. The COVID-19 pandemic placed restrictions such as social distancing, which led to the digitalization of certain elements in CPD. This paper, based on a construction case in Norway, looks at the effects of the digitalization of CPD. This is done using three research questions: How is digitalized CPD achieved, what strengths and weaknesses arise when CPD is digitalized, and how can the digitalization of CPD improve? The research was done through a literature study and qualitative interviews of eight design participants from the research case. Findings show that the digital start-up session should not be used further, as it has negative ripple effects later in design in the form of less collaboration. Fully digital ICE sessions are effective and worth continuing in the future but are dependent on what type of work is scheduled. Phase scheduling should try to use physical post-it notes during a physical meeting, and later convert the schedule to a digital format.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"62 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":"116592293","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}

More construction companies are interested in reducing waste and increasing efficiency. However, one of the main barriers that prevent the construction industry from adopting more technological solutions for its projects is not being clear about the direct benefits that would be obtained. This paper proposes using design parameters applied in a user-friendly visual model to choose the benefit to obtain for designing a construction project. These benefits are displayed as key performance indicator (KPI) options for the construction project. An analysis was carried out in a matrix to obtain the most relevant design parameters for a robotic cell in offsite construction from a manufacturing (not architectural or visual/aesthetic) point of view. Additionally, the visual model is designed using a data visualization structure. The limit of the investigation involves not having the visual tool validated in a case of a real construction company. Additionally, the visual tool is only a guide that is not quantified.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"136 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":"116377589","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}

Therefore, many contractors do not trust the promises of designers and protect the construction schedule with schedule buffers that increase project lead times. To act upon this situation, several researchers have suggested using the Last Planner™ System (LPS) as a method for DM. Using two case studies, we present how the use of the LPS method as a tool for Daily Management (DAM) increases the reliability of the design and how, correspondingly, not using it can affect design reliability. So far, very little attention has been paid to the role of DAM in DM, and this short article seeks to provide new insights into this research gap for both researchers in the field and DM professionals. These early and exploratory results, despite the limited number of cases, can be utilised in further research as well as in practical project management, especially when the reduction of schedule buffers between construction and design is targeted.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"24 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":"114652422","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, effective adoption of process models is still limited; lack of guidance on which model type would be applicable in the given contexts, and an excessive focus on the design of the process models themselves instead of their implementation may be some of the reasons for this. This research investigates how process models should be used within infrastructure engineering design, considering also how different methods suit different purposes. Findings from an ongoing research project in the UK are presented, following case study as its research strategy. This paper reviews the use of process models and clarifies their relationships by describing the adopted models and comparing them with the models explored in the literature, increasing the understanding of process models within infrastructure engineering design.

The reduction of waste improves environmental performance by reducing GHG emissions. This research quantified the impacts of lean construction and VDC in reducing physical and operational wastes related to partition walls. The researchers observed worker activities at construction sites and compared them with observations from past projects. The activities were classified into value-adding and non-value-adding activities. The researchers observed the construction of different block types (gypsum, autoclaved aerated concrete, and concrete blocks) to estimate the operational wastes related to the construction method. The results showed that lean and VDC improved the value-adding activities using gypsum block to 68.4% compared to 25.8% in a traditionally managed project using concrete block, an improvement of 167%. Moreover, the embodied GHG emissions in the lean-VDC project per partition area are 12 kg CO 2 e m -2 compared to 58.4 kg CO 2 e m -2 in the traditionally managed project. The reduction in GHG emissions is due to reducing waste in the lean-VDC project and using more sustainable materials.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"1 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":"130937519","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}
