Despite previous studies that have discussed the role of each of them, the complementarity between LPS and LBPC still needs to be further explained by using core Lean Production concepts. Moreover, most implementations reported in the literature of those two planning models have been concerned with building projects. Only a few cases are related to infrastructure projects, which have different types of complexity in relation to conventional building projects. This paper reports the initial results of the development of a planning and control model for linear infrastructure projects. This investigation was based on a case study carried out in a construction company from Uruguay. The development of the model considers some specific complexity features of linear infrastructure projects, such as high uncertainty, and independent linear processes spread around large urban or rural areas. The main insights provided by this study are concerned with devising a flow-based planning and control tool for look-ahead planning, the definition of criteria for devising location-based systems, the emphasis of work-in-progress control, and the use of visual management. design the company, and implementation in one pilot project; (iii) the planning and control model, by combining LPS and LBPC, and implementation in the three pilot projects; and (iv) definition of standard practices for production system design (PSD), and production planning and control. PSD can be described as collaborative and systemic pre-construction planning exercise, as described Barth et al. The proposed model for planning and control was built on what kept several existing good practices.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"4 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":"124802003","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 a paucity of data from real life case studies that affirm Scrum can benefit construction execution. This paper reports on a 20-week Scrum implementation across seven teams on a construction project that must achieve a critical building weathertight milestone. The study adopted a mixed-methods approach utilising case study design and data collected from a literature review, project documentation review, direct observation, purposeful semi-structured interviews, and a focus group workshop. Scrum complements Last Planner ® System (LPS) implementations and brings specific benefits at point of work execution by reducing weekly missed tasks resulting in increased and more reliable Planned Percent Complete (PPC). An 11 percent increase in average PPC accrued from utilising Scrum to complement LPS by reducing reasons for non-completion (RNC) of work tasks at crew level work interfaces. Additional softer benefits in the form of enhanced inter-trade communications and collaboration, as well as greater involvement of the entire crew in striving to achieve task execution. Further in-practice and academic research is required in aligning construction processes and methodologies with the concepts and definitions found in Scrum.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"14 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":"126508279","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, the preliminary process to identify a substantiated list constituting the interests, desires, requirements, and design essentials of different stakeholders on projects is still vague and unorganized. Establishing the Value Attributes List (VAL) is considered fundamental for delivering value. Thus, to answer the question of how to develop the VAL, a set of guidelines and steps are provided. The process was constructed by performing action research and engaging two case studies depicting two Canadian public projects. This paper also provides a generic list of value attributes to be the starting point for the project team. The list included the major categories to be considered on projects. Findings suggested that developing a customized team-led list is particularly important and pursuing a clear direction on the subsequent steps for monitoring is required. The research concludes that an in-house advocate is needed to (1) promote the process and move it onward, and (2) to make sure the whole team and project stakeholders understand the importance of these value discussions.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"58 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":"123961839","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}

Notwithstanding the benefits, lean value stream mapping can be enhanced to dynamically reflect the statistical productivity and economic improvements to enhance the process efficiency of production lines. Findings reported in the literature points to the benefits of integrating simulation-based tools with traditional lean value stream mapping in a hybrid framework to validate the feasibility of a given improvement. The main criteria are to reduce lean waste, increase productivity, and dynamically optimize manufacturing trade-offs for push–pull and just-in-time production systems by enhancing the efficacy of lean value stream mapping using a simulation-based approach. In this context, the proposed framework leverages value stream mapping to visualize the production system's current state. It then integrates the discrete-event simulation model in order to assess the various lean improvement scenarios proposed that to transform the system to its future state. The framework is implemented in a window manufacturing production stream to test and validate its feasibility in a mass customization environment. The case study results demonstrate the value of the framework in assisting decisions-makers to evaluate different scenarios and visualize their impact for better transformation.","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":"121418888","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, the WS categories have exhibited variation throughout history due to interpretation and application discrepancies. This lack of consensus on what represents Value-Adding-Work (VAW) and Non-Value-Adding-Work (NVAW), has hindered the use of data from previous WS studies for further analysis. For this reason, this research aims to understand how the data obtained from the WS application can be analyzed to discuss value. To address this question, the authors adopted a case study as the primary research strategy. The phenomenon of the present study comprises the activities involved in the renovation process in residential buildings. The phenomenon is studied through the application of the WS technique. The authors adopted previous analyses from the existing literature and proposed new types of analyses. The discussion section presents various kinds of analysis based on a breakdown of categories into codes: (1) general analysis; (2) a category breakdown analysis; (3) one single component/material analysis; (4) recategorized activities analysis; and (5) correlation analysis. The proposal of a detailed code classification, named breakdown work sampling, represents the main novelty of this study.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"8 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":"129162142","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}

This paper aims to identify how the synergies between Lean and BIM have been happening in practical and real-life applications and compare them with the Sacks et al.

We carried out semi-structured interviews with three construction companies to identify the interactions between Lean and BIM in their processes. As a result, we identified synergies in both Sacks et al. (2010) and the construction companies' practices; other synergies were identified only in Sacks et al. (2010), while others were identified only in the companies interviewed. These new interactions may be due to the technological advances during the last decade that made possible new uses of BIM or the level of implementation of Lean and BIM by companies, amongst other factors. This work contributes to technical and scientific knowledge since it brings a practical view of a topic that has a more theoretical approach. With the results, we can indicate the more common interactions to be implemented by companies, creating a safer way to be followed by companies seeking to implement Lean and BIM.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"22 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":"129304423","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}

Modular construction offers a high level of off-site value creation, and consequently leaner processes associated to the well-known off-site construction advantages as waste management, shorter project timeline, improved health and safety conditions for workers, better quality control, optimal material handling, and efficient working stations. Nonetheless, the on-site activities needed to connect the modules are often identified as critical sources of waste. In response, many connecting devices and models for calculations were developed in recent years, but very few present an automated locking mechanism for modular connection. While most connecting devices include the use of fasteners that need to be manually fixed to complete the connection of modules, an automated connecting device could significantly reduce the quantity of on-site activities by including an engineered mechanism that ensures self-lock. This research aims to evaluate the impact on leanness of an automated connecting device as well as to present a new plug-in self-lock device.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"31 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":"115941567","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}

This study presents the case of a panelized construction company that has embraced the lean philosophy over the past decade. Experiments undertaken during the process of building a digital twin of the company’s production facility to verify the logic underlying the developed model reveal an increase in productivity. Using the same productivity regression models to model framing operations in two different years, the simulation of combined productive and delay times results in an underestimation compared to actual production data from 2013 but an overestimation compared to actual production data from 2017. Moreover, prominent lean changes implemented over the years that are positively correlated with productivity improvement are identified. These include standardizing the design and manufacturing processes, minimizing waste (including Mura, Muda, and material waste), ensuring a continuous flow, balancing the production line, following a just-in-time approach for the delivery of materials and implementing the 5S program. The findings underscore the long-term benefits of adopting lean thinking in construction manufacturing.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"95 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":"116032637","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}
