Road environment modeling using robust perspective analysis and recursive Bayesian segmentation

Recently, vision-based advanced driver-assistance systems (ADAS) have received a new increased interest to enhance driving safety. In particular, due to its high performance–cost ratio, mono-camera systems are arising as the main focus of this field of work. In this paper we present a novel on-board road modeling and vehicle detection system, which is a part of the result of the European I-WAY project. The system relies on a robust estimation of the perspective of the scene, which adapts to the dynamics of the vehicle and generates a stabilized rectified image of the road plane. This rectified plane is used by a recursive Bayesian classi- fier, which classifies pixels as belonging to different classes corresponding to the elements of interest of the scenario. This stage works as an intermediate layer that isolates subsequent modules since it absorbs the inherent variability of the scene. The system has been tested on-road, in different scenarios, including varied illumination and adverse weather conditions, and the results have been proved to be remarkable even for such complex scenarios.

New Methodology for Integrating Teams into Multidisciplinary Project Based Learning

This paper describes the collaboration among students and professors in four different subjects, to develop multidisciplinary projects. The objective is to simulate the conditions in a company environment. A new methodology based on student interaction and content development in a Wiki environment has been developed. The collaborative server created an ‘out of the classroom’ discussion forum for students of different subjects, and allowed them to compile a ‘project work’ portfolio. Students and professors participated with enthusiasm, due to the correct well-distributed work and the easiness of use of the selected platform in which only an internet connected computer is needed to create and to discuss the multidisciplinary projects. Quality of developed projects has been dramatically improved due to integration of results provided from the different teams.

Risk sharing with Multilateral Financial Institutions in infrastructure and energy project financing : effect on capital relief for commercial banks

(Matsukawa and Habeck, 2007) analyse the main instruments for risk mitigation in infrastructure financing with Multilateral Financial Institutions (MFIs). Their review coincided with the global financial crisis of 2007-08, and is highly relevant in current times considering the sovereign debt crisis, the lack of available capital and the increases in bank regulation in Western economies. The current macroeconomic environment has seen a slowdown in the level of finance for infrastructure projects, as they pose a higher credit risk given their requirements for long term investments. The rationale for this work is to look for innovative solutions that are focused on the credit risk mitigation of infrastructure and energy projects whilst optimizing the economic capital allocation for commercial banks. This objective is achieved through risk-sharing with MFIs and looking for capital relief in project finance transactions. This research finds out the answer to the main question: "What is the impact of risk-sharing with MFIs on project finance transactions to increase their efficiency and viability?", and is developed from the perspective of a commercial bank assessing the economic capital used and analysing the relevant variables for it: Probability of Default, Loss Given Default and Recovery Rates, (Altman, 2010). An overview of project finance for the infrastructure and energy sectors in terms of the volume of transactions worldwide is outlined, along with a summary of risk-sharing financing with MFIs. A review of the current regulatory framework beneath risk-sharing in structured finance with MFIs is also analysed. From here, the impact of risk-sharing and the diversification effect in infrastructure and energy projects is assessed, from the perspective of economic capital allocation for a commercial bank. CreditMetrics (J. P. Morgan, 1997) is applied over an existing well diversified portfolio of project finance infrastructure and energy investments, working with the main risk capital measures: economic capital, RAROC, and EVA. The conclusions of this research show that economic capital allocation on a portfolio of project finance along with risk-sharing with MFIs have a huge impact on capital relief whilst increasing performance profitability for commercial banks. There is an outstanding diversification effect due to the portfolio, which is combined with risk mitigation and an improvement in recovery rates through Partial Credit Guarantees issued by MFIs. A stress test scenario analysis is applied to the current assumptions and credit risk model, considering a downgrade in the rating for the commercial bank (lender) and an increase of default in emerging countries, presenting a direct impact on economic capital, through an increase in expected loss and a decrease in performance profitability. Getting capital relief through risk-sharing makes it more viable for commercial banks to finance infrastructure and energy projects, with the beneficial effect of a direct impact of these investments on GDP growth and employment. The main contribution of this work is to promote a strategic economic capital allocation in infrastructure and energy financing through innovative risk-sharing with MFIs and economic pricing to create economic value added for banks, and to allow the financing of more infrastructure and energy projects. This work suggests several topics for further research in relation to issues analysed. (Matsukawa and Habeck, 2007) analizan los principales instrumentos de mitigación de riesgos en las Instituciones Financieras Multilaterales (IFMs) para la financiación de infraestructuras. Su presentación coincidió con el inicio de la crisis financiera en Agosto de 2007, y sus consecuencias persisten en la actualidad, destacando la deuda soberana en economías desarrolladas y los problemas capitalización de los bancos. Este entorno macroeconómico ha ralentizado la financiación de proyectos de infraestructuras. El actual trabajo de investigación tiene su motivación en la búsqueda de soluciones para la financiación de proyectos de infraestructuras y de energía, mitigando los riesgos inherentes, con el objeto de reducir el consumo de capital económico en los bancos financiadores. Este objetivo se alcanza compartiendo el riesgo de la financiación con IFMs, a través de estructuras de risk-sharing. La investigación responde la pregunta: "Cuál es el impacto de risk-sharing con IFMs, en la financiación de proyectos para aumentar su eficiencia y viabilidad?". El trabajo se desarrolla desde el enfoque de un banco comercial, estimando el consumo de capital económico en la financiación de proyectos y analizando las principales variables del riesgo de crédito, Probability of Default, Loss Given Default and Recovery Rates, (Altman, 2010). La investigación presenta las cifras globales de Project Finance en los sectores de infraestructuras y de energía, y analiza el marco regulatorio internacional en relación al consumo de capital económico en la financiación de proyectos en los que participan IFMs. A continuación, el trabajo modeliza una cartera real, bien diversificada, de Project Finance de infraestructuras y de energía, aplicando la metodología CreditMet- rics (J. P. Morgan, 1997). Su objeto es estimar el consumo de capital económico y la rentabilidad de la cartera de proyectos a través del RAROC y EVA. La modelización permite estimar el efecto diversificación y la liberación de capital económico consecuencia del risk-sharing. Los resultados muestran el enorme impacto del efecto diversificación de la cartera, así como de las garantías parciales de las IFMs que mitigan riesgos, mejoran el recovery rate de los proyectos y reducen el consumo de capital económico para el banco comercial, mientras aumentan la rentabilidad, RAROC, y crean valor económico, EVA. En escenarios económicos de inestabilidad, empeoramiento del rating de los bancos, aumentos de default en los proyectos y de correlación en las carteras, hay un impacto directo en el capital económico y en la pérdida de rentabilidad. La liberación de capital económico, como se plantea en la presente investigación, permitirá financiar más proyectos de infraestructuras y de energía, lo que repercutirá en un mayor crecimiento económico y creación de empleo. La principal contribución de este trabajo es promover la gestión activa del capital económico en la financiación de infraestructuras y de proyectos energéticos, a través de estructuras innovadoras de risk-sharing con IFMs y de creación de valor económico en los bancos comerciales, lo que mejoraría su eficiencia y capitalización. La aportación metodológica del trabajo se convierte por su originalidad en una contribución, que sugiere y facilita nuevas líneas de investigación académica en las principales variables del riesgo de crédito que afectan al capital económico en la financiación de proyectos.

Strengthening communication skills in an innovative context of engineering project management learning

This document presents an innovative, formal educational initiative that is aimed at enhancing the development of engineering students’ specific competences when studying Project Management (PM) subject. The framework of the experience combines (1) theoretical concepts, (2) the development of a real-case project carried out by multidisciplinary groups of three different universities, (3) the use of software web 2.0 tools and (4) group and individual assignments of students that play different roles (project managers and team members). Under this scenario, the study focuses on monitoring the communication competence in the ever growing PM virtual environment. Factors such as corporal language, technical means, stage, and PM specific vocabulary among others have been considered in order to assess the students’ performance on this issue. As a main contribution, the paper introduces an ad-hoc rubric that, based on previous investigations, has been adapted and tested for the first time to this new and specific context. Additionally, the research conducted has provided some interesting findings that suggest further actions to improve and better define future rubrics, oriented to communication or even other competences. As specific PM subject concerns, it has been detected that students playing the role of Project Managers strengthen their competences more than those ones that play the role of Team Members. It has also been detected that students have more difficulty assimilating concepts related to risk and quality management. However those concepts related with scope, time or cost areas of knowledge have been better assimilated by the students.

A Web-based Support System for Providing Effective Monitoring, Feedback and Evaluation in Project Management Education

This work introduces a web-based learning environment to facilitate learning in Project Management. The proposed web-based support system integrates methodological procedures and information systems, allowing to promote learning among geographically-dispersed students. Thus, students who are enrolled in different universities at different locations and attend their own project management courses, share a virtual experience in executing and managing projects. Specific support systems were used or developed to automatically collect information about student activities, making it possible to monitor the progress made on learning and assess learning performance as established in the defined rubric.

An ITS architecture specification - The FOTsis project experience

The recent continuous development of Cooperative ITS has resulted in several initiatives which focus on different parts of the Cooperative environment landscape. The FOTsis project focuses on the infrastructure side of the Cooperative environment and will deploy and test 7 services designed to maximise the benefits of the integration of the road operator and infrastructure-based information providers into the ITS environment. This integration can take place in any of the stages of data collection, processing and actuations of the services, but also support and trigger external tasks such as operations of the emergency response entities, etc. This paper describes the current status of the project and focuses on the specification of the supporting architecture to the services tested: references, a brief outline of the requirements’ definition, and the FOTsis architecture proposal, with some conclusions about the architecture tests conducted. The outlook on the project’s next steps is given in the last section of the paper.

Constructed Fashion: The Catwalk System as an Architectural Project

Teniendo en cuenta que no hay nada que se escape de la moda 1, y extendiendonos más allá de esta manida discusión sobre intersecciones formales, esta investigación propone la pasarela como un lugar real de mediación entre moda y arquitectura. Asumiendo esta condición, la pasarela encarna nuevos modos de producción apropiándose de su espacio y estructura, y convierténdose en una máquina capaz de generar múltiples y más bien infinitos significados. La moda es sin duda un proyecto creativo, que ha venido utilizando la pasarela como un marco para la reordenación de su narrativa visual, renovándose asi mismo como fenómeno social. Este proyecto de investigación plantea, que contrariamente las tipologías actuales de las pasarelas no nos facilitan la comprensión de una colección – que suele ser el objetivo principal. Presentan en cambio un entorno en el que se acoplan diferentes formatos visuales, -con varias capas-, conviéndolo en una compleja construcción y provocando nunerosas fricciones con el espacio-tiempo-acción durante el proceso de creación de otros territorios. Partiendo de la idea de la pasarela como un sistema, en el que sus numerosas variables pueden producir diversas combinaciones, esta investigación plantea la hipótesis por la cual un nuevo sistema de pasarela se estaría formando enteramente con capas de información. Este escenario nos conduciría a la inmersión final de la moda en los tejidos de la virtualidad. Si bien el debate sobre la relevancia de los desfiles de moda se ha vuelto más evidente hoy en día, esta investigación especula con la posibilidad del pensamiento arquitectónico y como este puede introducir metodologías de análisis en el marco de estos desfiles de moda, proponiendo una lectura de la pasarela como un sistema de procedimientos específicos inherente a los proyectos/procesos de la arquitectura. Este enfoque enlaza ambas prácticas en un territorio común donde el espacio, el diseño, el comportamiento, el movimiento, y los cuerpos son ordenados/organizados en la creación de estas nuevas posibilidades visuales, y donde las interacciones activan la generación de la novedad y los mensajes. PALABRAS CLAVES moda, sistema, virtual, información, arquitectura Considering that there is nothing left untouched by fashion2, and going beyond the already exhausted discussion about formal intersections, this research introduces the catwalk as the real arena of mediation between fashion and architecture. By assuming this condition, the catwalk embodies new modes of production that appropriates its space and turns it into a machine for generating multiple if not infinite meanings. Fashion, as a creative project, has utilized the catwalk as a frame for rearranging its visual narrative and renewing itself as social phenomena. This research disputes, however, that the current typologies of catwalks do not facilitate the understanding of the collection – as its primary goal - but, instead, present an environment composed of multi-layered visual formats, becoming a complex construct that collides space-time-action in the creation of other territories. Departing from the analysis of the catwalk as a system and how its many variables can produce diverse combinations, this research presents the hypothesis that a new system is being formed entirely built out of information. Such scenario indicates fashion´s final immersion into the fabrics of virtuality. While the discussion about the relevance of fashion shows has become more evident today, this research serves as an introductory speculation on how architectural thinking can introduce methodologies of analysis within the framework of the fashion shows, by proposing a reading of the catwalk as a system through specific procedures that are inherent to architectural projects. Such approach intertwines both practices into a common territory where space, design, behaviour, movement, and bodies are organized for the creation of visual possibilities, and where interactions are triggered in the making of novelty and messages.

Cooperative ITS communications architecture: the FOTsis project approach and beyond

With the continuous development in the fields of sensors, advanced data processing and communications, road transport oriented intelligent applications and services have reached a significant maturity and complexity. Cooperative ITS services, based on the idea of sharing accurate information among road entities, are currently being tested on a large scale by different initiatives. The field operational test (FOTsis) project contributes to the deployment environment with services that involve a significant number of entities out of the vehicle. This made necessary the specification of an architecture which, based on the ISO ITS station reference architecture for communications, could support the requirements of the services proposed in the project. During the project, internal implementation tests and external interoperability tests have resulted in the validation of the proposed architecture. At the same time, these tests have had as a result the awareness of areas in which the FOTsis architecture could be completed, mainly to take full advantage of all the emerging and foreseeable data sources which may be relevant in the road environment. In this study, the authors will outline an approach that, based on the current cooperative ITS architecture and the SmartCities and Internet Of Things (IoT) architectures, can provide a common convergence platform to maximise the information available for ITS purposes.

Transport interchange and local urban environment integration

Among the different interchange design aspects, integrated land use and infrastructure planning is maybe one of the most problematic fields in practice, given that a joint transport and urban planning spills over the regular scope of action of interchange developers, whereas it involves the cooperation and agreement of various authorities. Not only this, but the very issue of land use-transport integration seems to be a long-standing mantra in planning and transport research, lacking scientific evidence. This paper is an output of an ongoing European research project called ?NODES - New tOols for Design and OpEration of Urban Transport InterchangeS?. Its aim is to start re-focusing the academic-scientific evidence on the question and to foresee a specific and practical framework to approach the problem. The underlying hypothesis is that the interchange could be a catalyst of life and security in the city.

El análisis de la construcción sin pérdidas (Lean Construction) y su relación con el Project & Construction Management : propuesta de regulación en España y su inclusión en la ley de la ordenación de la edificación

El presente trabajo se basa en la filosofía de la Construcción sin Pérdidas (“Lean Construction”), analizando la situación de esta filosofía en el sector de la edificación en el contexto internacional y español, respondiendo las siguientes preguntas: 1. ¿Cómo surge el “Lean Construction”? 2. ¿Cuáles son sus actividades, funciones y cometidos? 3. ¿Existe regulación del ¨Lean Construction” en otros países? 4. ¿Existe demanda del ¨Lean Construction” en España? 5. ¿Existe regulación del ¨Lean Construction” en España? 6. ¿Cómo debería ser la regulación ¨Lean Construction” en España? 7. ¿Cuál es la relación del “Lean Construction” con el “Project & Construction Management”? 8. ¿Cómo debería ser la regulación de “Lean Construction” en España considerando su relación con el “Project & Construction Management”? Las preguntas indicadas las hemos respondido detalladamente en el presente trabajo, a continuación se resume las respuestas a dichas preguntas: 1. El “Lean Construction” surge en agosto de 1992, cuando el investigador finlandés Lauri Koskela publicó en la Universidad de Stanford el reporte TECHNICAL REPORT N° 72 titulado “Application of the New Production Philosophy to Construction”. Un año más tarde el Dr. Koskela invitó a un grupo de especialistas en construcción al primer workshop de esta materia en Finlandia, dando origen al International Group for Lean Construction (IGLC) lo que ha permitido extender la filosofía a EEUU, Europa, América, Asia, Oceanía y África. “Lean Construction” es un sistema basado en el enfoque “Lean Production” desarrollado en Japón por Toyota Motors a partir de los años cincuenta, sistema que permitió a sus fábricas producir unidades con mayor eficiencia que las industrias americanas, con menores recursos, en menor tiempo, y con un número menor de errores de fabricación. 2. El sistema “Lean Construction” busca maximizar el valor y disminuir las pérdidas de los proyectos generando una coordinación eficiente entre los involucrados, manejando un proyecto como un sistema de producción, estrechando la colaboración entre los participantes de los proyectos, capacitándoles y empoderándoles, fomentando una cultura de cambio. Su propósito es desarrollar un proceso de construcción en el que no hayan accidentes, ni daños a equipos, instalaciones, entorno y comunidad, que se realice en conformidad con los requerimientos contractuales, sin defectos, en el plazo requerido, respetando los costes presupuestados y con un claro enfoque en la eliminación o reducción de las pérdidas, es decir, las actividades que no generen beneficios. El “Last Planner System”, o “Sistema del Último Planificador”, es un sistema del “Lean Construction” que por su propia naturaleza protege a la planificación y, por ende, ayuda a maximizar el valor y minimizar las pérdidas, optimizando de manera sustancial los sistemas de seguridad y salud. El “Lean Construction” se inició como un concepto enfocado a la ejecución de las obras, posteriormente se aplicó la filosofía a todas las etapas del proyecto. Actualmente considera el desarrollo total de un proyecto, desde que nace la idea hasta la culminación de la obra y puesta en marcha, considerando el ciclo de vida completo del proyecto. Es una filosofía de gestión, metodologías de trabajo y una cultura empresarial orientada a la eficiencia de los procesos y flujos. La filosofía “Lean Construction” se está expandiendo en todo el mundo, además está creciendo en su alcance, influyendo en la gestión contractual de los proyectos. Su primera evolución consistió en la creación del sistema “Lean Project Delivery System”, que es el concepto global de desarrollo de proyectos. Posteriormente, se proponen el “Target Value Design”, que consiste en diseñar de forma colaborativa para alcanzar los costes y el valor requerido, y el “Integrated Project Delivery”, en relación con sistemas de contratos relacionales (colaborativos) integrados, distintos a los contratos convencionales. 3. Se verificó que no existe regulación específica del ¨Lean Construction” en otros países, en otras palabras, no existe el agente con el nombre específico de “Especialista en Lean Construction” o similar, en consecuencia, es un agente adicional en el proyecto de la edificación, cuyas funciones y cometidos se pueden solapar con los del “Project Manager”, “Construction Manager”, “Contract Manager”, “Safety Manager”, entre otros. Sin embargo, se comprobó la existencia de formatos privados de contratos colaborativos de Integrated Project Delivery, los cuales podrían ser tomados como unas primeras referencias para futuras regulaciones. 4. Se verificó que sí existe demanda del ¨Lean Construction” en el desarrollo del presente trabajo, aunque aún su uso es incipiente, cada día existe más interesados en el tema. 5. No existe regulación del ¨Lean Construction” en España. 6. Uno de los objetivos fundamentales de esta tesis es el de regular esta figura cuando actúe en un proyecto, definir y realizar una estructura de Agente de la Edificación, según la Ley de Ordenación de la Edificación (LOE), y de esta manera poder introducirla dentro de la Legislación Española, protegiéndola de eventuales responsabilidades civiles. En España existe jurisprudencia (sentencias de los tribunales de justicia españoles) con jurisdicción civil basada en la LOE para absolver o condenar a agentes de la edificación que son definidos en los tribunales como “gestores constructivos” o similares. Por este motivo, en un futuro los tribunales podrían dictaminar responsabilidades solidarias entre el especialista “Lean Construction” y otros agentes del proyecto, dependiendo de sus actuaciones, y según se implemente el “Lean Project Delivery System”, el “Target Value Design” y el “Integrated Project Delivery”. Por otro lado, es posible que el nivel de actuación del especialista “Lean Construcción” pueda abarcar la gestión del diseño, la gestión de la ejecución material (construcción), la gestión de contratos, o la gestión integral de todo el proyecto de edificación, esto último, en concordancia con la última Norma ISO 21500:2012 o UNE-ISO 21500:2013 Directrices para la dirección y gestión de proyectos. En consecuencia, se debería incorporar adecuadamente a uno o más agentes de la edificación en la LOE de acuerdo a sus funciones y responsabilidades según los niveles de actuación del “Especialista en Lean Construction”. Se propone la creación de los siguientes agentes: Gestor del Diseño, Gestor Constructivo y Gestor de Contratos, cuyas definiciones están desarrolladas en este trabajo. Estas figuras son definidas de manera general, puesto que cualquier “Project Manager” o “DIPE”, gestor BIM (Building Information Modeling), o similar, puede actuar como uno o varios de ellos. También se propone la creación del agente “Gestor de la Construcción sin Pérdidas”, como aquel agente que asume las actuaciones del “gestor de diseño”, “gestor constructivo” y “gestor de contratos” con un enfoque en los principios del Lean Production. 7. En la tesis se demuestra, por medio del uso de la ISO 21500, que ambos sistemas son complementarios, de manera que los proyectos pueden tener ambos enfoques y ser compatibilizados. Un proyecto que use el “Project & Construction Management” puede perfectamente apoyarse en las herramientas y técnicas del “Lean Construction” para asegurar la eliminación o reducción de las pérdidas, es decir, las actividades que no generen valor, diseñando el sistema de producción, el sistema de diseño o el sistema de contratos. 8. Se debería incorporar adecuadamente al agente de la edificación “Especialista en Lean Construction” o similar y al agente ¨Especialista en Project & Construction Management” o DIPE en la Ley de Ordenación de la Edificación (LOE) de acuerdo a sus funciones y responsabilidades, puesto que la jurisprudencia se ha basado para absolver o condenar en la referida Ley. Uno de los objetivos fundamentales de esta tesis es el de regular la figura del “Especialista en Lean Construction” cuando actúa simultáneamente con el DIPE, y realizar una estructura de Agente de la Edificación según la LOE, y de esta manera protegerlo de eventuales responsabilidades solidarias. Esta investigación comprueba que la propuesta de definición del agente de edificación DIPE, según la LOE, presentada en la tesis doctoral del Doctor Manuel Soler Severino es compatible con las nuevas definiciones propuestas. El agente DIPE puede asumir los roles de los diferentes gestores propuestos en esta tesis si es que se especializa en dichas materias, o, si lo estima pertinente, recomendar sus contrataciones. ABSTRACT This work is based on the Lean Construction philosophy; an analysis is made herein with regard to the situation of this philosophy in the building sector within the international and Spanish context, replying to the following questions: 1. How did the concept of Lean Construction emerge? 2. Which are the activities, functions and objectives of Lean Construction? 3. Are there regulations on Lean Construction in other countries? 4. Is there a demand for Lean Construction in Spain? 5. Are there regulations on Lean Construction in Spain? 6. How should regulations on Lean Construction be developed in Spain? 7. What is the relationship between Lean Construction and the Project & Construction Management? 8. How should regulations on Lean Construction be developed in Spain considering its relationship with the Project & Construction Management? We have answered these questions in detail here and the replies are summarized as follows: 1. The concept of Lean Construction emerged in august of 1992, when Finnish researcher Lauri Koskela published in Stanford University TECHNICAL REPORT N° 72 entitled “Application of the New Production Philosophy to Construction”. A year later, Professor Koskela invited a group of construction specialists to Finland to the first workshop conducted on this matter; thus, the International Group for Lean Construction (IGLC) was established, which has contributed to extending the philosophy to the United States, Europe, the Americas, Asia, Oceania, and Africa. Lean Construction is a system based on the Lean Production approach, which was developed in Japan by Toyota Motors in the 1950s. Thanks to this system, the Toyota plants were able to produce more units, with greater efficiency than the American industry, less resources, in less time, and with fewer manufacturing errors. 2. The Lean Construction system aims at maximizing the value of projects while reducing waste, producing an effective coordination among those involved; it manages projects as a production system, enhancing collaboration between the parties that participate in the projects while building their capacities, empowering them, and promoting a culture of change. Its purpose is to develop a construction process free of accidents, without damages to the equipment, facilities, environment and community, flawless, in accordance with contractual requirements, within the terms established, respecting budgeted costs, and with a clear approach to eliminating or reducing waste, that is, activities that do not generate benefits. The Last Planner System is a Lean Construction system, which by its own nature protects planning and, therefore, helps to maximize the value and minimize waste, optimizing substantially the safety and health systems. Lean Construction started as a concept focused on the execution of works, and subsequently the philosophy was applied to all the stages of the project. At present it considers the project’s total development, since the time ideas are born until the completion and start-up of the work, taking into account the entire life cycle of the project. It is a philosophy of management, work methodologies, and entrepreneurial culture aimed at the effectiveness of processes and flows. The Lean Construction philosophy is extending all over the world and its scope is becoming broader, having greater influence on the contractual management of projects. It evolved initially through the creation of the Lean Project Delivery System, a global project development concept. Later on, the Target Value Design was developed, based on collaborative design to achieve the costs and value required, as well as the Integrated Project Delivery, in connection with integrated relational (collaborative) contract systems, as opposed to conventional contracts. 3. It was verified that no specific regulations on Lean Construction exist in other countries, in other words, there are no agents with the specific name of “Lean Construction Specialist” or other similar names; therefore, it is an additional agent in building projects, which functions and objectives can overlap those of the Project Manager, Construction Manager, Contract Manager, or Safety Manager, among others. However, the existence of private collaborative contracts of Integrated Project Delivery was confirmed, which could be considered as first references for future regulations. 4. There is a demand for Lean Construction in the development of this work; even though it is still emerging, there is a growing interest in this topic. 5. There are no regulations on Lean Construction in Spain. 6. One of the main objectives of this thesis is to regulate this role when acting in a project, and to define and develop a Building Agent structure, according to the Building Standards Law (LOE by its acronym in Spanish), in order to be able to incorporate it into the Spanish law, protecting it from civil liabilities. In Spain there is jurisprudence in civil jurisdiction based on the LOE to acquit or convict building agents, which are defined in the courts as “construction managers” or similar. For this reason, courts could establish in the future joint and several liabilities between the Lean Construction Specialist and other agents of the project, depending on their actions and based on the implementation of the Lean Project Delivery System, the Target Value Design, and the Integrated Project Delivery. On the other hand, it is possible that the level of action of the Lean Construction Specialist may comprise design management, construction management and contract management, or the integral management of the entire building project in accordance with the last ISO 21500:2012 or UNE-ISO 21500:2013, guidelines for the management of projects. Accordingly, one or more building agents should be appropriately incorporated into the LOE according to their functions and responsibilities and based on the levels of action of the Lean Construction Specialist. The creation of the following agents is proposed: Design Manager, Construction Manager, and Contract Manager, which definitions are developed in this work. These agents are defined in general, since any Project Manager or DIPE, Building Information Modeling (BIM) Manager or similar, may act as one or as many of them. The creation of the Lean Construction Manager is also proposed, as the agent that takes on the role of the Design Manager, Construction Manager and Contract Manager with a focus on the Lean Production principles. 7. In the thesis it is demonstrated that through the implementation of the ISO 21500, both systems are supplementary, so projects may have both approaches and be compatible. A project that applies the Project & Construction Management may perfectly have the support of the tools, techniques and practices of Lean Construction to ensure the elimination or reduction of losses, that is, those activities that do not generate value, thus designing the production system, the design system, or the contract system. 8. The Lean Construction Specialist or similar and the Specialist in Project & Construction Management should be incorporated appropriately into the LOE according to their functions and responsibilities, since jurisprudence has been based on such Law to acquit or convict. One of the main objectives of this thesis is the regulate the role of the Lean Construction Specialist when acting simultaneously with the DIPE, and to develop a structure of the building agent, according to the LOE, and in this way protect such agent from joint and several liabilities. This research proves that the proposal to define the DIPE building agent, according to the LOE, and presented in the doctoral dissertation of Manuel Soler Severino, Ph.D. is compatible with the new definitions proposed. The DIPE agent may assume the roles of the different managers proposed in this thesis if he specializes in those topics or, if deemed pertinent, recommends that they be engaged.
