The paper describes how the design and construction project team implemented CBA throughout the project pursuit, including details surrounding the team’s preparation and decisions developed during confidential conversations with the Owner. Ultimately the team implemented CBA when selecting the structural system, external facade, and the project programming. The researchers integrated the Owner's perspective to understand the motive(s) to utilize the CBA decision making method, why they chose the winning team, and the ways CBA methodologies were implemented beyond the project pursuit phase. This paper presents unique viewpoints, from both the project team and Owner’s, on the benefits of using CBA during project pursuit and beyond. The aim of sharing this case study is to inspire more owners to request the use of the CBA method at the start of the project. Choosing By Advantages simplifies the internal decision-making process, which many team find as a challenge. CBA allows for project teams to approach owners with a decision-making process that allows for optimal owner feedback leading to productivity and clarity within the phases of the project.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"41 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":"115407080","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}

Previous studies on environmental impact reduction have often focused on technical aspects rather than organisational aspects. The value stream mapping (VSM) method has been extended to capture and improve environmental performance by systematically adopting lean methods in the manufacturing process. However, in the construction field, this approach encounters difficulties establishing state maps and considering the interrelationships between different processes in an uncertain and dynamic environment. This study proposes a hybrid approach combining Multi-Agent Systems (MAS) and System Dynamics (SD) based on process patterns to overcome these obstacles. First, process patterns, including activity packages, are developed to assist the VSM in creating state maps and identifying environmental impact sources. Then, construction operations with their state maps and needed resources are modelled as autonomous agents containing causal-effect loops (SD modules) in a MAS model. These agents interact with each other to describe the construction operating mechanism. Finally, different lean methods are analysed to find opportunities to improve environmental performance.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"99 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":"123786690","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}

Production metrics (PM) are being used to assess the impact of these methods on project performance during run-time. A lack of common vocabulary hinders comparison of PM, making it difficult to repeat strategies used for improving project performance and for benchmarking PM across projects. Through a detailed content analysis, 2 datasets of 904 PM reported by 195 Virtual Design and Construction (VDC) practitioners in Scandinavia and Latin America were curated. Qualitative coding was used to categorize the PM into the three key VDC elements, i.e., Integrated Concurrent Engineering (ICE), Building Information Modeling (BIM) and Project Production Management (PPM) and to validate the categorization. This research enabled a comparison of PM categories across the two regions for the first time. PM categorized as ICE and PPM were reported by more than 68% professionals in both the regions. BIM PM had a disparity in reporting (Scandinavia: 30%, Latin America: 91%). It also opened a pathway to develop a common vocabulary of PM to compare, benchmark and standardize PM across VDC implementations. Technology (NTNU) and Universidad De Lima (ULima). AEC professionals enrolled in the VDCCP learn the fundamentals of VDC in a 1-week introductory workshop and implement VDC on their ongoing projects for 9 months.

As a project delivery method, strategic partnering shares similarities with the Lean project delivery perspective as they both seek to achieve more collaborative projects. The paper has structured strategic partnering into three essential Lean Construction (LC) elements: contract, organization, and collaboration. Consequently, this paper contributes to knowledge about strategic partnering between contractors and designers by answering the two research questions: 1) How is the current practice associated with strategic partnering, and 2) What are the experiences with strategic partnering between contractors and designers. An exploratory case study was conducted to examine how strategic partnering can be improved in future projects. A combination of literature review and semi-structured interviews were used for data collection. The findings reveal an improvement potential when implementing strategic partnering in the construction industry. The paper concludes that more attention should be paid to contract elements and the project organization at the company levels to improve strategic partnering. However, at the individual level, good effects have been identified. Findings also showed that external factors like political decisions can lead to postponements and thus changes in personnel in the organization.","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":"129624100","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 study was conducted using a case study on an industrial construction project in which LPS had been in use since its start. Research data were collected using a semi-structured survey conducted online due to the pandemic. The study also utilized project progress data and measurement data from the LPS sessions. The most interesting result of the study was how little the LPS participants felt they had to compromise their goals. We also found how scheduling methods used in parallel with LPS can frustrate users and contribute to reducing its usefulness. Our findings can be used in further research in several ways, either by utilising the questionnaire we developed or by comparing our findings to other studies. We believe that practitioners using LPS will benefit from our results and can use them to address these shortcomings identified in future projects.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"77 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":"131094402","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}

Such transactions are synchronously held by computer nodes in distributed copies, with cryptographic signatures validated through consensus protocols and transparency achieved through peer-to-peer transactional access among the nodes. Blockchain-based applications can be preferred over centralized databases on the basis of high levels of trust, data security, immutability, transparency, and multi-user consensus protocols. There is growing interest in blockchain in the built environment, with a focus on procurement, the management of supply chain project-life cycle, smart cities, intelligent systems, sustainability, and decentralized organizations. However, there is little discussion on whether and how blockchain will affect the advances in lean construction (LC) and vice versa. This paper therefore proposes a framework that establishes interactions between blockchain and lean construction, which can potentially facilitate the implementation of both. It is based on a synthetic literature review. The results indicate that blockchain can facilitate the implementation of LC (e.g., recording and retrieving of Last Planner data), and vice versa (e.g., value stream mapping guiding the integration of blockchain with processes).","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":"132669173","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 objective was to reduce structural rebars' assembly times, replace the traditional on-site processes of cutting, bending, and assembling steel with an industrial process based on systems of PRC steel elements. As a result, the assembly times of the structural item were reduced by 31%, thanks to the use of PRC elements. In addition, due to the VDC methodology, a 100% buildable design of the PRC elements was achieved. optimization tools to solve complex challenges in construction projects.

The topic of complexity in construction projects was first raised in the Nineties before it in the early 2000s was introduced on the Lean Construction and IGLC agenda. When facing a complex problem, there are two possible strategies to pursue with reference to the Cynefin framework for complexity. The first is to transform and move the problem into the complicated or even simple domain, thereby making it manageable. The second is to handle the problem within the complex domain. The dominant approach within both Project Management and Lean is the first, namely, to emphasize efficiency, flow, standardization, best practice, planning, reliability, and control. The paper challenges this lop-sidedness by pointing out its potential reductionism and argues that we should also appreciate, exploit, and take advantage of complexity instead of just combatting it. Value creation is reliant upon both strategies and is therefore not a question of either or, but of balance and trade-offs based on an inherent dualism.","PeriodicalId":111246,"journal":{"name":"Proc. 30th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"35 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":"114975061","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}
