Documenting how successful that knowledge transfer is taking place can be helpful to those wishing to efficiently introduce lean into their own OAEC organizations. Lean educational efforts within academic settings have been brought to light through earlier publications. This research identifies the content of lean construction courses from five US-based universities to add to the seven previously documented. Tabulated results revealed that: (a) the content of lean curricula is evolving as grading formats, types of readings, and numbers and types of simulations have grown; and (b) lean curricula as defined by the Associated General Contractors (AGC) lean certification program is starting to permeate academic coursework. This may be a testament that AGC lean certification is providing some advantage in career placement for students. Investigation of the evolution of lean education within academia helps us better understand a driver of change as students enter the OAEC industry following graduation. The intent of this paper is to document this moment in time, as well as to raise a question about the potential impact of curriculum standardization on future continuous improvement initiatives with respect to lean construction philosophy, methods, and tools, in the OAEC industry.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"13 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132386408","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}

Considering the Lean Construction concepts, waste definitions and Value Stream Mapping, added to an Operational Excellence perspective, the paper bring the result of nine infrastructure projects conducted by a consultancy company in seven Brazilian Construction Companies. In the presented analysis, eight projects took place in Brazil and one in Trinidad and Tobago. The methodological analysis here presented consists of two standard phases of the referred consultancy projects where on-site and data analysis, construction value stream mapping, and “gemba-walk” are used to understand the project and quantify the level of value-adding activities and wastes in the construction process. The Multi Moment Analysis will be used to measure wastes and value added in operations performed on-site. The results show a low level of value-adding activities, representing, in the general analysis, 26% percent of the total available time. The results are also divided for project and type of operation, i.e. earthworks, steel assembly, pre-fab, for example. That analysis brings the possibility to understand specifics characteristics of each project product and different approaches towards planning and production control and a new managing attitude in each company. This understanding was hold in those construction companies and may be a great improvement opportunity for the infrastructure construction sector.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"298 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133141554","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}

Building Information Modelling (BIM) has been driving information management in design, but its use has yet to be described in a way which makes it compatible with planning tools such as Last PlannerTM. Level of Development (LOD) could allow for this by attributing maturity to the BIM-model, yet previous studies of LOD implementation have shown potential for improvement. This paper researches current approaches, experiences and requirements for using maturity-based management in design. A study of two large projects with maturity-based management using interviews and an analysis of measurements was conducted in addition to a literature scoping study. The paper formulates five aspects of BIM-based workflows which needs to be addressed in order to manage their development. In addition, the study reveals how use of maturity-based management can provide a foundation for managing BIM-based workflows according to lean principles. Finally, the paper concludes with practical recommendations for enabling lean design with management of model maturity, such as how to specify maturity levels or how to disaggregate the model into disciplinary sections.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134357689","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}

Researchers have observed that Sustainability and Lean implementation go hand in hand and there are benefits in implementing them together as ‘Sustainable Lean Construction’ (SLC). However, it was observed through a literature review that the contractors' top management support for implementing sustainable practices was not as evident as that of Lean implementation. In the Indian construction scenario, with the Sustainability initiatives and Lean implementation in preliminary stages, time is ripe for viewing them as concepts that complement each other and look for its widespread application as a combined credo. Commitment by owner organizations, compatibility with an existing contractual framework, design ability, constructability, government policy support, financial attractiveness, long-term relationship and increased market penetration are among the enablers that support the implementation of SLC in Indian conditions. The identified enablers and action points, therefore, pave the way for achieving the benefits of lean implementation and sustainable construction practices for fostering SLC practices in Indian construction.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122341643","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}

While the principles and practices of both are found to benefit construction processes; there are limited studies that elucidate their synergies and demonstrate the value for teaching lean in construction management programs. VSM visually maps a process and identifies areas for possible improvement. However, it is directly applicable on assembly line operations in a manufacturing industry, an environment which the civil engineering students may not be familiar with, and therefore require experiential learning. To this end, the process of conversion of 2dimensional (2D) design drawings to a 3D building information model of a construction project was foremost captured through VSM technique in an experimental study consisting of 4 student teams. The action learning methodology allowed the teams to generate the current state map, identify wastes in the process and aim for an ideal future state through kaizen efforts and brainstorming sessions. The experiment helped to reinforce the VSM technique in teaching lean and allowed the students to present appropriate opportunities for improvement. Lessons learnt can further act as a stepping stone to benefit professionals in actual practice.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129160377","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}

Integrated Project Delivery (IPD) seeks to improve project performance through a high level of collaboration between key participants. Although IPD is a well-known delivery model, only a single project has implemented this approach in the Norwegian construction industry: The Tønsberg Project. The purpose of this study is to identify which theoretical IPD elements are used in this project, document experiences from IPD and provide recommendations for the delivery of future IPD projects in Norway. This article presents research based on a comprehensive literature review and a case study of the first Norwegian IPD project. The case study consists of a document review and 9 semi-structured interviews with key informants. The experiences established through this research indicate that a higher level of collaboration facilitates innovative design and effective execution. The interviewees consider IPD to have potential to improve the performance of future projects but describe change in culture to be crucial for project success. This study presents challenges and benefits experienced in The Tønsberg Project. It provides practitioners with a framework of theoretical IPD elements and first-hand experiences with how these elements can affect project performance.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123243336","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 this type of structural engineered wood product, timber is glue laminated to increase its constructive strength. Laminated-timber represents an opportunity to lower GHGemissions, while traditional on-site cast concrete is believed to be cheaper. The study examines differences between construction in laminated timber and cast concrete, and pros and cons associated with construction in laminated timber. The study began with a literature review. Then the construction of two neighboring apartment buildings that used Last-Planner during both design and construction were studied. Takt-planning was used in the production planning. Twelve interviews represent the main source of data and was supplemented with a study of documents and direct observations in design meetings. Use of laminated timber requires more resources in the design phase compared with the use of cast concrete. Fire and acoustic regulations, in particular, demand new construction guidelines. However, use of laminated timber saves time and provides a cleaner working environment during construction. Under the right circumstances, laminated timber appears to outperform on-site cast concrete. This study suggests Lean measures for contractors that want to benefit from the advantages of laminated timber and improve such construction.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122949600","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}
