By monitoring productivity, a Project Team can more effectively identify and respond to “hot topics” that may hinder flow and predictability. The consistent communication of this information provides the transparency needed for decentralized decision-making, empowering the Project Team to take action and maximize value. Through an Integrated Form of Agreement on a Southern California healthcare project, self-performing Constructors tracked and reported productivity. This information was used to provide real-time updates to schedule, production planning, and budget forecasting. These metrics were compared to the original rates, serving as key performance indicators. Underperforming critical activities would be earmarked to conduct a Deming Cycle for improvement. Activities with high measures would be assessed to identify factors contributing to their success or if the baseline was ill defined. Ultimately, this information was used for Continuous Improvement with a goal of reducing overall schedule in productivity improvements, reducing overall budget by way of production savings, and contributing to and maintaining a positive work environment.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"192 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":"116408559","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 paper examines the case of flat roof constructions. It is based on an assumption that current practice might lead to a risk of premature roof failures. Within the case of flat roof constructions, we seek to answer the following research questions:  What are the main threats to the value for the client in the case of flat-roof constructions?  How does the client govern in order to oversee that requirements are met regarding construction materialsand assembling? The research was explorative in nature and limited to the Norwegian context; based on a scoping literature study and seven semi-structured in-depth interviews with experienced industry actors. The findings show that in a short-term perspective, the divergence of stakeholder interest and premature roof failures present a great threat to the value of the building. Poor procuring and handling threatens the construction process. It is a source of disputes between the contractor and the client. Furthermore, it constitutes an obstacle in creating long-term value for the client. Flat-roof constructions are particularly exposed. We propose that clients should implement a more structured approach to overseeing that client requirements are met. To ensure a lean project delivery and maximizing value, mitigating unwanted events related to suppliers and materials are crucial.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"6 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":"128052825","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}

Thus, there is a need for a better understanding of Phase Schedule implementation practices and the impacts of those on production planning and control. This paper presents the results of the implementation and evaluation of the LPS focusing on the Phase Schedule practices based on two in-depth case studies developed from April 2016 to August 2017 in Salvador-Brazil. The Case Studies involved the implementation of the LPS and the Phase Schedule practices and the analysis of the impact of using those practices on the production planning and control processes. The findings indicated that the cycles of the Phase Schedule improve the constraints analysis, collaboration between those involved, transparency in the planning process, adherence between levels planning by using performance metrics, reliability of plans and commitment to the deadlines. Also, the activities which were initially not analyzed as critical, have strong influence on the performance of the production planning and control.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"9 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":"126016626","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, the ambiguity in identification of values by clients renders the task complex and challenging. The investigation of the dynamics involved in stakeholder definition of the project values entails the need for research methods used in social sciences. This paper first presents the process of client value generation and evolution based on an ethnographic study of the architect selection process of two institutional buildings. The study consists of participant and non-participant observations of the project conceptualization and architect selection process. It is observed that along with client requirements incorporated in architectural design, the design delivery efficiency criteria of the architect have equal considerations in architect selection. Therefore, the values in Architecture Engineering and Construction (AEC) design can be categorized into Project Design Delivery Values (PDDVs) and Architectural Design Values (ADVs). The paper proposes a framework for the evaluation of design of a built facility using suitable Multi-Criteria Decision Making (MCDM) technique.","PeriodicalId":419313,"journal":{"name":"26th Annual Conference of the International Group for Lean Construction","volume":"120 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":"123310421","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}

Waste is commonly interpreted as waste of material even though, waste in construction industry also relates to activities such as defects, movement, waiting time and processing. Such waste can be minimised through an in-depth understanding of the organisation. Herein, Value Chain Management (VCM) can be used to facilitate organisations to categorise the activities in terms of their value addition. The generic value chain model developed by Porter in 1985 focuses on the manufacturing industry thus, a framework is required for contractor organisations based on which Value Adding Activities (VAAs) and non-VAAs can be identified. This paper is aimed at proposing a conceptual model for VCM in contractor organisations. Three case studies were conducted in selected contractor organisations and data was collected through fifteen semi-structured interviews. Collected data was analysed using content analysis. Altogether, 46 VAAs were identified classified under four primary functions and six secondary functions. The findings were used to develop a VC model applicable to contractor organisations based on Porter’s generic VC model. This in turn could be used by contractors to adopt strategies to enhance Value Adding Activities (VAAs) and to minimise non-VAAs.","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":"122275184","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}
