Literature review shows that the volume and quality of data enabling situational awareness during construction projects is increasing with the use of new technologies, such as indoor positioning systems and other applications of Internet of Things (IoT). However, these information streams have been used individually so far. BIM as the interface integrating different streams of situational awareness information can result in better data-driven construction management and production. This study suggests that using BIM in 3D visualization of the indoor positioning of construction resources (workers, material, and equipment) enables visual management based on situation awareness on construction project activities. Better situational awareness of construction resources on-site based on visualization in BIM can improve the identification and elimination of waste and the identification of workflow interruptions, potentially permitting better planning and increasing productivity. The study suggests further steps for empirical research to prototype the concept and validate it with industry partners and practitioners.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127809118","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}

By breaking down the work to be done in so-called manageable chunks, work structuring plays an important role in the creation of flow. The optimisation of flow is important due to the fragmented nature of the industry. Despite successful examples of the application of these methods, it is believed that the advantages remain limited to achieving better project results. Where current examples organise working packages around the work of different trades, this paper explores the consequences of a more supply chain-driven approach to collaborative work structuring. It challenges trades to design a “Supply Chain Rhythm”. The results presented in this paper show additional advantages, where multidisciplinairy teams have been created within a project. This way, the configuration of the crew performing the work chunk exceeds the boundaries of organisations or trades, and leads to further optimisation of the work flow.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"24 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":"125244275","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, very few studies have sought to examine the relationship between the organisational, commercial and institutional environments influencing construction procurement and the generation of process waste in construction projects. This study addresses this gap in knowledge by providing findings from a case study of a major UK infrastructure project. \u0000The study identifies a number of prevailing, yet counterproductive, procurement and contractual governance practices that lead to a ‘network of causal wastes’. The study provides a conceptual model which exposes the complex, dynamic, interconnectedness and reciprocal nature of waste at the procurement and supply-chain level. The authors believe that this is the first study to expose the nature of waste at this level of analysis. It uses an integrated grounded theory case-study methodology that is demonstrably effective and can be useful for supporting studies seeking to investigate the concept of waste within the construction procurement context. The study concludes by suggesting that future studies focus on pre-procurement processes.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"24 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":"116647597","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 focus of this pioneering approach is first to understand that certain behaviors lead to conversations in which expectations are clearly identified and understood by the different project participants, and then to set measurable acceptance criteria so that the final result can be compared with what was agreed. Previous research has described the approach and provided positive results in satisfying client’s expectations, but the process to achieve such outcomes has not been captured. This paper captures the implementation of this behavior-based quality (BBQ) approach to quality management, that has as its main goal to have no surprises, zero rework, and to improve delivery of value to all the project participants engaged at any point of a construction project. Construction projects are to be planned first for quality to fully understand expectations of what the team should build, then for safety to identify any potential risks associated with the processes to build the agreed work and define how tasks will be built in a safe manner, and then for production to secure flow and an adequate use of resources.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"13 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":"126035243","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 results derived from a Pareto chart and an affinity analysis in which lean tools were reduced to 23 categories, show that the main practices of lean manufacturing and lean construction are Last Planner System, Building Information Models, Visual Management, among others. This study is part of a subsequent project that will take the conclusions of this qualitative analysis to suggest a guiding tool (based on the continuous improvement tools found) that correlates applicable lean approaches with the main actors of the supply chain of high value housing projects in Bogotá.

The proposed method was implemented for 20 weeks in a case study on a construction project. The data collection included construction site 3D mapping generation, visual comparison of 4D BIM and 3D mapping status, measurement of performance indicators, and structured interviews. The evaluation focused on the following research constructs: compliance with the planned goals, impact on the construction progress deviations, transparency, and collaboration. The main findings indicate an improved integration of progress analysis and decision-making, improvement of progress deviations’ identification, and allowed for better compliance with planned goals and increased transparency and collaboration.

However, key construction project actors find it difficult to analyse whether prefabrication would be beneficial for their project with specific circumstances and targets. This research aims to develop a process to evaluate the impact of prefabrication in projects. First, based on the literature review and focus group discussion, we define the impact factors of prefabrication. Second, we apply Choosing by Advantage (CBA) approach together with Cost-Benefit-analysis to define a process for prefabrication impact measurement which considers various impact factors and their importance in the project. Finally, we validate the process with the industry experts. The paper contributes to knowledge on robust decision-making processes about production methods in situations in which all impact factors are not easily comparable but require a subjective valuation.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"18 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":"114182794","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}

Since then, more than ten pilot projects have tested the method. So far, limited research has been carried out to explore the contractors’ experiences on BVP to improve the method for future projects. The purpose of this paper is to fill part of this research gap by exploring a contractor’s experiences from several projects using the method. By looking at five road projects that have tested out the BVP method, a trend can be seen in how the evaluation of the offers was conducted. Data was collected from five pilot road projects through three in-depth interviews with key persons and a document study. The results show how the evaluation of the price aspect has changed over time. In three of the five projects, a formula was used that urged the contractors to set prices low in order to score additional points. This formula gained criticism from both the contractors and the BVP experts hired to help the contractors. BVP has contributed, to a certain extent, to Lean implementation. However, the practice should be improved to increase value and transparency and minimize conflict and waste.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"33 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":"114267424","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}

Key learning points from the case study were derived by structured interviews with construction staff directly involved and by noting similarities of the lean deployment to recommendations made in the literature.

However, few studies have approached the production problem in terms of the entire industry. This paper consequently elaborates on the challenges and the importance of a collaborative environment in the construction industry because construction is complex, with the main operations produced within temporary and sociotechnical systems. Through a conceptual exploration, this paper combines theories on networks, boundaries, open systems, and loose and tight couplings to assesses the consequences of temporality and how integrated project delivery (IPD) tighten couplings in the industry. Finding show that because projects are temporary, they challenge the multilevel connections of networks needed for the industry’s evolution to become more productive. However, theories on open systems and tight and loose couplings indicate that IPD enable a cooperative network environment. Thus, the boundaries of cooperative delivery models will enable a stronger link between change and process, industry and projects, needed for a socio-technical process in construction.","PeriodicalId":278113,"journal":{"name":"Proc. 27th Annual Conference of the International Group for Lean Construction (IGLC)","volume":"44 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":"122116430","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}
