Main goal of Project Construction Management and Project Management is to delivery a project within scope, times and costs planned, obtaining a high quality standard. Instead, Lean Construction is focused on minimizing waste, in favor to creating maximum value for the client. The question to which this empirical research wants to answer is following: the integration of Project Construction Management and Lean Construction techniques could affect positively the respect of times and costs planned? To answer to the question it ideated a method that integrates the techniques of two methodologies. Then it applied in the architectural project of simulation in order to show the potentiality of the method. The workflow divided into three stages. At first stage, they identified the individual assegnments through Work Breakdown Structure. At second stage, it defined the Organizational Breakdown Structure. At last stage they planned the construction times and costs through Priced Bill of Quantity, Cost Breakdown Structure, Gantt Chart and Last Planner® System. The hypothesis on expected results deriving from the application of the method and they could led to thinking an improvement of project performance in terms of times and costs planned, respect to only Project Construction Management techniques. Future researches could be experimental, involving enterprises ed implementing the methodology in real study cases, using also the Building Information Modelling.

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.

La industria de la construcción es una parte importante del aparato económico de un país, por tanto, la verificación de los nuevos sistemas de gestión que se implementan en las principales industrias constructoras del mundo y en donde se obtienen excelentes resultados, merece especial atención. En el presente artículo se hace una revisión bibliográfica de la filosofía Lean Construction (LC) o “construcción sin pérdidas”, un nuevo enfoque en la gestión de proyectos de construcción introducido por el profesor Lauri Koskela en el año 1992 basándose en el modelo empleado por la industria automovilística en los 80, la “producción Lean”. Koskela propone que la construcción es un sistema de producción que se funda en proyectos con gran incertidumbre en la planificación y una mala concepción de la producción, que es vista como un modelo de transformación solamente. Las bases teóricas de LC propuestas por Koskela pretenden ver la producción en la construcción como un proceso de transformación, de flujo y generador de valor, en consecuencia, el objetivo de Lean Construction es crear buenos sistemas de producción que permitan optimizar, reducir o eliminar los flujos para mejorar los tiempos de entrega. En este sentido, LC es un nuevo pensamiento en gestión de proyectos de construcción que desafía a la guía de gestión actual del Project Management Institute PMBOK, con un alto auge en los Estados Unidos, De ahí que LC no deba ser concebido como un modelo o sistema en el cual solo se siguen unos pasos, sino como un pensamiento dirigido a la creación de herramientas que generen valor a las actividades, fases y etapas de los proyectos de construcción. Entendiendo el valor como la eliminación de todo aquello que produzca perdidas en la ejecución de las mismas. En la fase de construcción por ejemplo, la reducción de los tiempos de ejecución en las actividades de obra, el control del desperdicio de los materiales y la prevención de accidentes laborales son objetivos que si se logran cumplir agregaran valor a tal fase. Basados en estos principios teóricos los investigadores Glenn Ballard y Greg Howell idearon una herramienta denominada Last Planner o como se conoce actualmente en Latinoamérica Sistema del Ultimo Planificador con el objetivo de mejorar el proceso de programación de obra proponiendo la renovación del concepto de planificación de obra tradicional, en donde las actividades que serán hechas se desarrollan sin saber realmente si las pueden hacer realidad en obra. Lo que hace el SUP es considerar el conjunto de actividades que realmente pueden hacerse de una manera más específica para controlar más de cerca los impedimentos que eviten la ejecución de estas en obra, de esta forma la probabilidad de que las actividades programadas se lleven a cabo es muy alta y como consecuencia la incertidumbre de no poderlas hacer disminuye y se evitan retrasos en la realización de los trabajos en obra. Como parte del desarrollo de la filosofía Lean Construction en el marco de crear herramientas Lean para la mejora de la gestión de los proyectos de construcción, se analiza como contrasta con el modelo tradicional de ejecución de proyectos diseño-licitación-construcción, en cuanto a cuál es la mejor forma de organización arquitecto, cliente y constructor en las fases de desarrollo del proyecto. La base teórica del modelo Integrated Project Delivery IPD propone unificarlos en la fase de diseño para obtener el máximo entendimiento del proyecto para que la fase de construcción se desarrolle sin choques entre el arquitecto y el constructor. Al aplicarle Lean construction al modelo IPD se convierte en el sistema de ejecución de proyectos Lean Project Delivery System (LPDS) el cual propone la metodología para desarrollar los proyectos de construcción bajo cinco fases y 12 etapas Lean en las cuales también se fomenta el desarrollo de herramientas que contribuyan con la generación de valor. La tecnología de modelado 3D Building Information Modeling BIM aunque no hace parte de LC es por ejemplo una herramienta de ayuda muy importante para el modelo LPDS, contribuye a comprender mejor los procesos constructivos de diseños complejos o simples para el ahorro de tiempo en su construcción. Bajo este paradigma de ayuda que brinda BIM se deja planteada una visión sobre su futuro desarrollo como parte de Lean Construction.

Building information modelling has become a core topic in the architectural engineering and construction (AEC) industry, and its benefits have been realised over different phases of project construction. Adoption of nD BIM in the domain of infrastructure projects has provided challenges and is yet evolving. This chapter reviews the adoption of Building information modelling in the management of infrastructure projects. The use of nD planning (4D, 5D, 6D, 7D, and 8D planning) in infrastructure planning and management is discussed through Mapping n-D BIM with different applications in infrastructure projects. 4D BIM models are developed integrating the 3D models with the schedule and they support multiple construction management tasks. The implementation of 4D planning and management in infrastructure projects is demonstrated with the help of two case studies.

The construction industry continues to experience productivity rates that lag behind other industries. Additionally, an increasingly competitive market and a decreasing skilled labor pool are challenging construction firms. Prefabrication and offsite modular construction techniques offer alternatives to traditional site-built construction methods that have the potential to provide improved productivity as well as other added benefits. Prefabrication methods, applied effectively, offer results that produce value to the project team. Such value includes improved productivity and efficiency in construction operations, reduced project costs, reduced schedule durations, and improved safety, increased levels of quality and improved sustainability and waste reduction. Currently the implementation of prefabrication and offsite construction techniques on the construction project remains subjective and unstandardized. The aim of this research is to develop a framework that will assist the project team to make decisions regarding the use of prefabrication and modular construction based on factors that have proven to be the most successful in implementing modern methods of construction. The concentration is on emphasizing the use of Building Information Modeling and Lean Construction methods as catalysts to maximize the effectiveness of the use of modular offsite construction. This research is primarily toward the use of prefabrication and modular construction methods for vertical construction and should prove valuable for all project players including Owners, Designers and Constructors. The development of this framework utilizes information compiled through interviews and case studies to develop a proposed framework for implementing prefabrication and off-site modular construction techniques at the project level. The framework will be validated in the future using a Delphi survey to qualitatively generate quantified data on the best methods to implement prefabrication and offsite construction techniques.

Lean construction (LC) and building information modeling (BIM) are two of the prominent concepts challenging the traditional practices in construction management. Small and medium-sized enterprises (SMEs) often constitute the largest group in construction supply chains. Increasing BIM and LC adoption amongst SMEs is a key condition for achieving the transformation of the construction industry through BIM and LC. The paper presents a systematic literature review of the adoption of (i) LC, (ii) BIM, and (iii) both LC and BIM in SMEs to evaluate the current literature, and 114 papers were included in the review. The bibliographic and content characteristics of the literature were discussed in detail. It was found that despite the importance of SMEs, the current LC and BIM literature falls short in terms of both number of publications and content of publications. The paper concludes with some generic suggestions for future research and action.

This study compares the national curriculum of Iran and the UK to find out how the educational system indeveloping countries such as Iran can be improved. Because of implementing thinking skills and cognitive education,the educational system in the UK benefits from a high-quality standard. The science of mind, brain, educationintroduces some principles to improve teaching and learning methods and provide thoughtful and lifelong learnersfor the societies. In this study, we specified the main parts of the national curriculum in both countries and selectedsome of the principles to determine whether these two countries apply them in their national curriculum. Some ofthese principles focus on some significant issues: teaching models, the use of Meta-discipline and HolisticTechniques, authentic learning experiences, use of products, processing and progressing Evaluations, developingexplicit learning objectives, how to benefit from thinking and reflective practices, using collaborative and democraticactivities, preparing students to set personal objectives, giving themselves feedbacks, technology and flippedclassrooms, and beginning Year- Round Schooling. The results show that Iran needs more precise and detailedlearning objectives in its curriculum, use of democratic and collaborative activities with academics and students,develop thinking and reflective practices which play vital roles in upgrading the educational system. Moreover, it issuggested that the UK and Iran should consider embedded evaluations and flipped classrooms to meet the needs ofnew generation of learners.

El objeto de este trabajo fue establecer propuestas de mejoramiento al proceso de planeación de tiempos y costos en la etapa de cimentación de un edificio, a partir de la integración de herramientas como simulación de eventos discretos, programación con líneas de balance y metodologías Building Information Modeling - BIM. A partir de mediciones en campo se levantó información para la elaboración de un modelo de simulación de eventos discretos que imitara el proceso constructivo real. Se propusieron y modelaron alternativas de mejora, a partir de los principios de la filosofía Lean Construction y la programación de líneas de balance encontrando reducciones en tiempo y costo. También se realizó la animación virtual de las alternativas a partir de metodologías BIM. Se concluye que la integración de las herramientas utilizadas es de gran utilidad en la planeación y toma de decisiones en un proyecto civil.
