This process is apparent in nature where it is evolving towards the optimum solution. Lean is defined as a philosophy that aims at eliminating waste in production processes without compromising value. The two concepts appear in the literature as independent with little attempts to study a possible relation between them. The purpose of this paper is to explore synergies between the two seemingly distinct systems. This is performed by studying each notion on its own through breaking it down to its dynamic functional systems, and comparing the functions of each against one another. Findings reveal that the development of lean since its inception is comparable to the natural mechanisms of evolutionary design in nature. Findings suggest that lean is the natural course of evolution of construction management systems towards more optimal systems. Constructal Law provides us with a perspective about the concept of evolution and the direction of these evolutionary changes with time. The continuous evolution of everything is never out of control. Plotting the history of the covered territory against time shows an S-shaped curve. Every spreading flow has an S-shaped history of growth. It starts with an initial slow growth, followed by a much faster growth and a slow growth again.","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":"128631020","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 achieve production flow, field managers rely on work structuring methods to enable them to structure activities and flows. Current work structuring methods enable field managers to structure activities, but they do not explicitly represent all seven construction flows or their movement through the project. Hence, field managers rely on their intuition and tacit understanding of flow sequencing, which can cause communication problems between stakeholders resulting in delays and productivity loss. This paper presents a work structuring method that allows field managers to explicitly represent construction activities, flows, and flow movement through the project. The work structuring method was tested prospectively at three construction sites with different scopes and planning methods. The work structuring method allows field managers to generate activity and flow-based schedules to plan and control the project. Furthermore, it improves stakeholder understanding of the plan by visually representing activities’ and flows’ interdependencies.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"81 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":"127661395","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 foundations for takted construction practices as well as the methods of Takt Planning and Takt Control have been described in numerous papers within the framework of the IGLC (Binninger u. a. 2017a; Frandson u. a. 2013; Frandson und Tommelein 2016; Haghsheno u. a. 2016; Heinonen und Seppänen 2016; Tommelein 2017). One of the primary goals of the methods is to create flow, allowing construction processes to be executed efficiently. In order to investigate the relationship between the methods TPTC and flow in takted construction projects, the issues of how flow is implemented in takted projects during Takt Planning and Takt Control as well as how this affects project participants were discussed. The foundations of the flow production principle were then outlined and an assessment method for determining the quality of flow was devised. The applied approach was based on the book “This is Lean” by Modig und Åhlström (2015). Hereby, workflows were measured from two perspectives and compared using an efficiency matrix. Data from practice in the form of takt plans from 40 takted projects were analyzed and empirically assessed. To date, an assessment of takted projects in relation to workflow has not been completed in any academic study. This paper provides a foundation for further research and sets a standard for assessment of flow in takted projects in real-life practice. This research serves as a pilot study in this field and invites further detailed studies of the characteristics of flow to be conducted in the future.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"150 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":"115183704","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 other countries of the world such the USA, UK, Brazil, Nigeria and Israel among others are seeking to understand this challenge and deploy innovative ways and modern techniques to improve it, limited studies have explored factors that contribute to non-value adding activities (NVA) in the Gibraltar construction industry. The current study aims to identify the factors that contribute to NVA on construction sites in Gibraltar and to present an outlook on how this could be minimised using Last Planner System(LPS). A combination of quantative and qualitative research approaches were used. Thirtyone questionnaire responses were analysed and seven semi-structured interviews were conducted. The investigation reveals that the development of unrealistic schedules, lack of adequate training, delayed approval process and work interruption due to the community are the key factors that contribute to NVA. The study found that the suggestions offered by construction professional for minimising NVA align with some LPS principles. The study concludes that some of the current practices, could serve as justification for the introduction of LPS in the construction sector of Gibraltar.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"154 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":"115001690","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 occurs, in part, due to the lack of evaluation tools that enable the acknowledgment of its true value for the companies. Thus, this paper aims to present an audit protocol to evaluate the level of lean implementation. Developed under Design Science methodological background, the audit protocol was proposed based on literature. To evaluate the applicability, the pilot protocol was implemented and tested into 4 construction companies from the city of Fortaleza, northeast of Brazil. The pilot revealed improvements to improve the protocol. Then, the improved protocol was evaluated and validated by 5 lean construction experts, resulting in the final protocol which was composed by 4 dimensions, 35 categories, 136 items and 223 examples of verifying evidences. Was verified that the protocol allows more than identify the lean implementation level, but enables a lean journey if used as a guidebook to lean implementation. The proposed audit protocol can be also used to cyclic evaluation that enables the improvements of the identified gaps, through a deep comprehension of the critical factors that can prevent the success of lean construction in the companies.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"34 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":"124970742","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}
