It will be interesting and beneficial to understand how project managers make making-do decisions when managing projects in different countries and cultures. This research conducted two surveys, one in China and one in the U.S., to study how making-do decision is made differently in two countries by project managers with various levels of experience and responsibility. The research also examined whether there is significant difference in experienced task starting time and duration variation between people with different making-do preference. Findings showed that there was a significant difference in making-do decision preference for construction managers in China vs. the U.S. However, there was no significant difference on making-do decision preference for managers at different responsibility levels. Results revealed Chinese managers who preferred making-do have experienced significantly higher duration variation while in U.S. the results are opposite. Emphasizing obedience, remaining consistency with peers and supervisors, and constantly checking labor, equipment, and materials availabilities are highly valued in the Chinese culture and management practice, which contributed to the making-do decision outcomes in China vs. the U.S. The findings help project managers to understand the difference and rationale in making-do decisions and have more efficient collaboration and communication when they work in projects located in a foreign country.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126585401","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 begins with an empirical account of the work a series of project teams did to prefabricate and install exterior wall (X-wall) panels on six different buildings. The authors then explain relevant aspects of Fujimoto theory. Finally, the authors create a framework for evaluating the work in light of this theory and do so. The authors find that Fujimoto’s theory is relevant to construction. This paper is limited because the construction data set is relatively small and the evaluation of the competitiveness of routines and learning is based on the assessment of the first author, who initiated and directly managed the work on two projects and was engaged in its development on later projects. The paper is relevant for industry professionals because Lean management and process capability is required to make value flow to customers. Lean Construction theory can advance by understanding the elements of capability-building in the auto industry and how they can be applied to design and construction.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129209814","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}

It seems that the principles have taken the position of being a significant part of lean thinking, meaning a knowledge that lean personnel should acquire. This article wants to support and emphasise the importance of lean principles as rules of living but believes in taking the power of the lean principles one step further. If a lean organisation, project or leader explicitly confronts each other with the principles, this empowers the individuals being challenged and may create an outcome that closely links the employee's know-how to the process. Using lean principles as the main message to be understood, they may pull in tools, methods, frameworks or systems to answer these principles. This paper reports from research that explores the effect of pushing lean principles as the direct challenger on employees. Skilled workers at construction sites are the receiver of both general principles but mainly rephrased into more operational language.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133931627","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 case investigated was an offshore wind turbine project in the British sector of the North Sea. This exploratory case study used a deductive approach studying the literature. The initial step was a review of the location-based scheduling literature. The applicability of the theory could be tested through understanding the patterns from existing location-based scheduling literature. These patterns were the adapted from the construction context to the offshore wind construction context. With the knowledge of how and why from a theoretical perspective, the authors analyzed the existing construction schedule which was based on the critical path methodology. The results from this analysis provided knowledge about how location-based scheduling is applicable from an industrial perspective. This research contributes knowledge by testing the theory of location-based scheduling in the context of offshore wind turbine construction industry.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134589902","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, issues of adapting collaborative practices and the time it takes firsttime users to understand TVD practices have been a challenge in TVD projects. Recently, there has been an increase in the creation, reinvention and use of simulations and serious games to teach TVD and other lean principles to project stakeholders encountering them for the first time. The 50 minute version of the simulation game developed in Texas A & M University was used to illustrate TVD practice and collaboration in this study. The study used 24 industry stakeholders from a reputable real estate developer during the implementation of TVD on a live project in Nigeria. The results reported that the simulation is effective in illustrating the practices of TVD including collaboration and designing to set targets. Finally, this study recommends the inclusion of the TVD simulation game in training and workshops for project team before the commencement of construction projects because it demonstrated to be a simple and practical method of understanding collaboration and TVD practices.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134630892","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 such design development meetings, architects, consultants, main contractor, subcontractors, and client representatives face several challenges in moving from conceptual designs to a documented set of shop drawings. This phase represents the peak of participants’ interactions including exploring and refining design solutions, explaining and reflecting on each other’s ideas and concerns, and negotiating design and cost decisions. Collaboration is often presented in the literature as practices that provide the platform for successful interaction and the achieved outcomes, but with minimal concern about actual interactive processes. Theoretically, collaboration has been studied from a variety of perspectives grouped into normative and practice-based approaches that have enhanced the research field at the inter-organisational macro-level, but there is no consensus on a framework to measure collaboration empirically in the field. Therefore, the aim of this paper is to explore the common themes describing interdisciplinary collaboration in the literature and develop a framework explaining the conceptual relationship between them. The proposed framework provides a preliminary step towards understanding the dynamic nature and stages of the interdisciplinary collaboration in the detailed design phase.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130848938","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}

With a background in Lean Manufacturing, and confronted with industry norms of low productivity, extensive subcontracting, unreliable plans, and incomplete information, the developer sought to ways to optimize construction cost, schedule and quality by and minimizing uncertainty and variation and by improving workflow. The developer sought to establish how Lean interventions might improve the performance of the production system that was being designed for the product. Specifically, the challenge was to determine how the concept of producing with laborers reorganized from trade-specific teams into multi-skilled work cells might impact the Makerhoods project, given the reality of the local construction market. To test these questions, Agent-Based Modelling was used. First, analogs of the local market and project of interest were recreated within the modeling environment. Next, the project delivery techniques were tested to find the highest probability of project success with the lowest band of outcome uncertainty. We hope the results will lead to new ways of approaching project management and potentially to establishment of new types of construction firms (i.e. the “finishing cells” composed of multi-skilled teams capable of completely building an apartment’s interior).","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114433859","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 pour cycle consists of one or more disconnected casting segments. Casting segments in the successor pour cycle often fill the gaps between the disconnected casting segments in the predecessor pour cycle. We call such a meeting of two neighbour casting segments “topological dependency” because it effects spatial conflicts between pour cycles and different trades cannot work on the next casting segment until the previous ones are completely finished. Because of the long curing times, trade crews have to wait or move to other locations. In this research, we introduce a new structure of a cycle planning option, which can avoid such spatial conflicts. We evaluated our cycle planning option by using a stochastic discrete event simulation model and compared it with three practical cycle planning options from one supervisor and two formwork engineers. The criteria for the evaluation were the total construction time as well as the stable production rate and balanced work. In addition, we discuss the potential benefit by using a mix of concrete precast elements and casting segments to achieve an even better production flow.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130408961","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}
