The main PDSs referred to in cited literature are: Design-BidBuild (DBB), Construction Management at Risk (CMR), Design-Build (DB), and Integrated Project Delivery (IPD). By applying statistical tests such as Analysis of Variance (ANOVA) F-test and Kruskal-Wallis H-test to a dataset of 109 projects, this paper compares the performance of the four PDSs. As a result, statistically significant performance differences among the examined PDSs were identified in five performance areas: cost, schedule, quality, communication, and change management. Furthermore, performing pairwise comparisons using post-hoc statistical tests to each pair of PDSs shows that DBB performs markedly worse than the other examined PDSs, especially IPD. The findings presented in this paper should encourage industry professionals to move away from the DBB model, and towards IPD and other synergic PDSs.","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":"128946011","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}

Decision makers must consider multiple social, environmental and economic aspects in order to achieve sustainable solutions. They must also manage interrelated information and preferences of different stakeholders to ensure that the policy suits the community and accomplishes its goals. This research study focused on analyzing the design process of environmental public policies using the Choosing by Advantages (CBA) decision system integrated with Design Structure Matrix (DSM) to make complex decisions. A case study involving the redesign of a waste collection program was conducted, where three complex decisions were made using the CBA method. Researchers proposed using DSM to decrease negative iterations by finding the optimal order of decisions. Using DSM helped to decrease the number of iteration loops, and document the assumptions to make the process more transparent. Future work should measure the impacts of using CBA together with DSM to make decisions in the formulation process of public environmental policies.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"52 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":"117088424","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}

Lean construction (LC) as operationalised by tools including the LPS has been deployed over 25 years with documented successful outcomes. Yet, the literature also reveals widespread implementation failures, in part due to a guidance shortfall. To address this issue, guidance principles were developed, informed by longitudinal action research (AR) undertaken over 18 months investigating LPS usage on 7 sequential projects on the ongoing refurbishment of a liquified natural gas (LNG) plant in North West Australia. AR, the main research method used, combined continuous experimentation with analysis using a variety of data and evidence sources. By examining the process and outcomes of the action, explanations and further ideas are forthcoming, setting the platform for new action. The paper describes further longitudinal LPS implementation aided by the developed guidance on a £1.5 billion UK infrastructure project. The research contributes to knowledge with ongoing LPS guidance development, through testing and refinement with AR cycles. Further guidance into the use and melding of off-site manufacture and lean construction practice is also being developed and deployed. The limitations are that only LNG refurbishment and infrastructure projects have been researched to date.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"38 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":"124980810","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, the implemented production system should support the interaction of the project team, enabling team members to develop a common understanding, and to reach the required quality and production performance when carrying out their daily activities. This research concludes that the Last Planner System (LPS) aligns to the Toyota Production System (TPS) and its recognized management theory, which is a vehicle to integrate the minds + hands philosophy within projects from early design phase till handover. Our findings show that adopting the LPS as a production system helps to align and integrate the project participants. Takt is a work structuring tool that can be integrated into the LPS, if the product allows (repeatable areas). Thus, we recommend that the production system be designed based on the team’s needs and the product requests.","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":"133844083","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}

To prove whether the current situation can be improved, the aforesaid production system is designed to assess the hypothesis that a true integration of BIM functionalities with the Last Planner System will contribute to a more efficient project delivery. Although beneficial synergies of BIM and Lean have been widely described and acknowledged in research, previous work has not fully addressed the stated hypothesis, since it has only provided frameworks on how to use BIM and the Last Planner System in parallel. The core of the here-proposed lean BIM-based production system is the linkage of BIM objects at data processing level with the Last Planner System routines making use of digital Kanban boards. The production system will also be extended by cost control aspects of the Earned Value Management approach and thus represents the basis for a complete construction management system with respect to quality, schedule and costs. This paper discusses the first concepts of the new lean BIM-based production system and introduces an information system integration model as a starting point for future software development activities.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"47 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":"133498565","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 Last Planner System (LPS) is designed to improve these circumstances through the enhancement of workflow reliability by involving various disciplines in joint planning processes and a culture of collaboration. How to actually measure related project team culture (PTC) is unknown at this stage. This paper tries to close this gap and compares two defined versions of the Ideal Lean Culture for organizations with the actual PTC in projects using the LPS. It first presents the two Ideal Lean Cultures for organizations, based on a framework developed for organizations (the Competing Values Framework - CVF). Next, it examines on the basis of three case studies the applicability of the CVF for measuring the actual culture in project teams using the LPS and compares it with the named Ideal Lean Culture conditions. The paper concludes that the CVF is a suitable tool to take a snapshot of the PTC and that the comparison to the Ideal Lean Culture can give conclusions about the current project team’s maturity in projects using the LPS.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"6 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":"127648530","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, limited research have focused on evaluating the attributes associated with those various systems needed to highlight their difference. In fact, off-site systems present different advantages and disadvantages implying a need to evaluate their value maximization in terms of cost, time, quality, etc. when selecting the appropriate offsite system. Although some research studies have attempted to compare off-site against onsite systems, none has performed a comparison among non-volumetric systems (e.g. panelized and natural materials), volumetric systems, and hybrid systems. Therefore, this paper takes the initial steps and presents work targeted towards identifying the optimal offsite systems for a given project by extracting and elaborately analyzing the attributes of the different systems using the Analytical Hierarchy Process technique (AHP). The outcomes of this study will yield standardized policies for properly choosing optimal off-site systems based on lean principles.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"10 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":"114397672","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}
