Current market conditions characterized by technological changes, increasing regulatory requirements and low funding make current construction management models obsolete. This tendency affects not only the private housing market but also public administration projects, which have large time and budget deviations across the board. As a result, new approaches are needed to improve the efficiency of the construction process, removing extra costs and delivering projects on time. The most representative trends in the construction industry that enable such improvements are both Building Information Modelling paradigm (BIM) and Lean Construction philosophy with one of its associated tools in the field of construction management—the Last Planner System. However, a review of the literature shows the scarcity of works on the synergy of both paradigms taking into account the extensive literature on Lean and BIM individually. This is further accused if we look beyond the theoretical literature reviews. Therefore, this paper is focused on the benefits derived from the synergy of both disciplines and the impacts on project efficiency through a case study of a public construction project at the university of Alicante in order to provide empirical evidence of the benefits and improvements of using BIM at the Look Ahead meetings and of the Last Planner System. Finally, the results of the case study allow us to make a comparison with the data related to cost deviations of other public projects with different uses, built areas, and complexity which were managed with traditional methods of construction.

Purpose The purpose of this paper is to investigate the implementation challenges of one of lean construction’s recent tools, the last planner system (LPS), by exploring issues in the New Zealand construction sector to identify potential areas for improvement. To achieve this aim, the study formulated two objectives: to present the challenges in LPS use and to explore solutions by using an Excel spreadsheet for facilitating LPS applications. Design/methodology/approach The study drew primarily upon a case study approach. A fieldwork study and document analysis of a New Zealand construction project were conducted with an extensive literature review undertaken on the LPS concept. Findings The findings revealed that although an automated spreadsheet could be a simple and inexpensive option for using the LPS, data collection, storage and transfer into the spreadsheet could significantly influence the reliability of the LPS outcomes. Most data utilisation challenges were found to occur around the three data sets included in the weekly work plan (WWP). The study presented several automation solutions which had been applied to overcome data utilisation challenges. Originality/value Among the first of its kind in the construction industry, this study, with its first-hand account of an organisation which uses the lean paradigm, provides an in-depth insight into LPS tool implementation. The study extends the current body of knowledge by unearthing the challenges of LPS integration into construction activities and presenting efforts undertaken in a construction case project to overcome relevant issues. This adds value by enhancing the reliability of the LPS and, consequently, the effectiveness of its implementation in practical terms.

AbstractThis article presents strategies for teaching scheduling methods such as takt-time, flowlines, and point-to-point precedence relations (PTPPRs) using building information modeling (BIM) models in the Last Planner System. This article is the extended version of the article entitled “Teaching Takt-Time, Flowline and Point-to-point Precedence Relations: A Peruvian Case Study,” which has been published in Procedia Engineering (Vol. 196, 2017, pages 666–673). A case study is conducted in final year students of civil engineering at the Pontifical Catholic University of Peru. The mock-up project is an educational building that has high repetitive processes in the structural works phase. First, traditional tools such as Excel spreadsheets and 2D drawings were used to teach production system design with takt-time, flowlines, and PTPPR. Second, 3D and 4D models with Revit 2016 and Navisworks 2016 were used to integrate the previous schedules with a BIM model and to identify its strengths and weaknesses. Finally, Vico Office was used for the automation of schedules and comparison of the methods in 4D and 5D. This article describes the lectures, workshops, and simulations employed, as well as the feedback from students and researchers. The success of the teaching strategy is reflected in the survey responses from students and the final perceptions of the construction management tools presented.

PurposeDocumented evidence supports the improvements resulting from the use of the Last Planner System® (LPS) as a lean construction technique; however, several barriers to the implementation of the technique have been identified. The purpose of this paper is to evaluate the implementation process of LPS by a project team that is transitioning from the traditional planning and control to LPS on a typical commercial project. The paper compares the adopted implementation process with that of the recommended best practices and identifies the overlaps and variances.Design/methodology/approachAn in-depth case study was conducted to accomplish the specific objectives: document the process of LPS implementation in detail; identify the overlaps and variance from the recommended practices; and investigate the causes for variance from the recommended practices. The authors used direct observations, document investigations and semi-structured interviews with key project participants to gather data. Constant comparison and content analysis were used as data analysis method for this study.FindingsThe paper identified critical barriers to the implementation process of LPS in the case study project, which are supported by existing literature and are considered typical of project teams that are new adopters and transitioning to the implementation of LPS.Research limitations/implicationsBased on a single case study, the outcomes may lack generalizability. However, similar findings of existing literature and evaluations by the project personnel substantiated the findings of the study.Originality/valueThe study attempted to conduct a systematic investigation on the implementation process of LPS, which is a less investigated topic. The paper draws attention to the major barriers experienced while adopting LPS in the case study project and suggested possible ways to address similar issues in the future. The barriers experienced by the case study project are typical of project teams who are new adopters and transitioning to the adoption of LPS, process and have the potential to be alleviated through the recommended practice implementation and process maintenance strategy.

Resumo O planejamento de médio prazo (PMP) consiste em um nível hierárquico de planejamento do Last Planner System (LPS) e destaca-se como estratégia primordial para garantir a concretização dos planos estabelecidos no planejamento de longo prazo no nível operacional de empreendimentos de construção. Este artigo descreve uma revisão sistemática da literatura (RSL) cujo objetivo foi identificar as principais práticas do PMP, as principais falhas em sua implementação e as lacunas de conhecimento sobre esse tema. Os resultados obtidos apontam a existência de amplo conjunto de práticas no PMP, que podem ser consideradas em futuras pesquisas, bem como incorporadas no processo de planejamento e controle da produção por empresas construtoras. Entretanto, constatou-se generalizada ineficácia em sua implementação. Também foram identificadas lacunas na literatura referentes ao impacto do PMP no desempenho das construções e quanto à aplicação do Building Information Modeling (BIM) para apoiar as funções do PMP. Conclui-se que são necessárias mais pesquisas que contribuam para aumentar a eficácia do PMP nos empreendimentos de construção, dado seu reconhecido impacto na remoção de restrições e, em consequência, na obtenção de fluxo ininterrupto das atividades.

Abstract Over the past few decades, construction productivity has been at a standstill. Lean and Building Information Modelling (BIM) is attracting increasing interest in the construction industry as a way to increase construction productivity. This paper aims to contribute to the body of knowledge by identifying hitherto unexplored opportunities for the use of BIM functionalities as a support and as facilitators of the application of lean practices in the construction phase. A systematic literature review was adopted as the methodological approach in this research, and reported case studies related to the scope of this paper were searched. The results show that lean practices can be classified into four degrees of BIM support based on the level of current exploration. Just one lean practice (the last planner system) has been extensively explored, three have been reasonably explored, and five have just been preliminarily explored. Five practices have not been explored at all. This research summarises the already studied and the potential additional uses of BIM functionalities to support each lean practice, showing that lean practices supported by BIM functionalities are still underused and that further studies can explore additional ways to support these practices. This study holds great value for a broader practical application of lean practices, bringing faster and easier results with more extensive BIM support.
