Book excerpt: La industria de la Construcción es un sector en el cual se invierten fuertes partidas económicas año con año, con el objetivo de mejorar las condiciones de vida de los seres humanos que habitan cierta región. En consecuencia, una de las partidas en donde los gobiernos gastan un importante porcentaje del ingreso público es en las obras de vialidad en una ciudad. Al realizar este tipo de proyectos, se observa hoy en día un problema para lograr la efectiva integración entre las fases iniciales de factibilidad, planeación y diseño con la etapa de construcción, lo cual provoca sobrecostos por re-trabajos por efecto de cambios en los proyectos e incremento en los plazos de ejecución. Esto anterior provoca problemas sociales debido al gran número de usuarios que utilizaran rutas alternas por al cierre de la vialidad durante la construcción de la infraestructura y que se traduce en demoras y horas-hombre perdidas. En las etapas iniciales de los proyectos de construcción, es donde se gasta la menor cantidad de los recursos económicos invertidos (alrededor de 5% - 10%). En esta etapa se realizan las actividades de factibilidad, planeación y diseño del proyecto, para definir las directrices con mayor trascendencia sobre las cuales se basaran todas las decisiones subsecuentes dentro del proyecto. El objetivo de la metodología es ordenar los procesos que se realizan al iniciar cada uno de los proyectos de infraestructura vial, llevando a cabo un análisis iterativo en las etapas iniciales para que en las actividades subsecuentes (comenzando por la elaboración de la ingeniería de detalle hasta la construcción y cierre de la obra) se ejecuten con cambios mínimos que no incrementen el presupuesto considerado inicialmente, ni tampoco incremente el periodo de ejecución estimado. En este trabajo se presentan 3 casos de estudio, en donde implementamos la metodología dentro de proyectos reales de infraestructura vial. En base a los resultados observados en los diferentes casos de aplicación, podemos decir que su implementación genera costos sumamente bajos, los cuales pueden considerarse despreciables en comparación de los beneficios que puede generar al visualizar los problemas y restricciones del proyecto anticipadamente. El costo de la implementación de la metodología, en todos los casos fluctuó entre $150,000 y $200,000 lo cual representa invertir alrededor del 0.3% al 0.4% del costo total del proyecto de infraestructura completo.

Book Synopsis Análisis de los estudios de preinversión e inversión para un proyecto de infraestructura vial by : Freddy Gutiérrez Faúndez
Download or read book Análisis de los estudios de preinversión e inversión para un proyecto de infraestructura vial written by Freddy Gutiérrez Faúndez and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: La presente investigación esta orientada a la formulación de proyectos en todas sus etapas tanto de preinversión como inversión. En el estado de preinversión se estudia la generación y análisis de idea de proyecto, estudio a nivel de perfil, estudio de prefactibilidad y de factibilidad. El estado de inversión estudia el diseño y la ejecución y además el estado de operación. Para poder realizar los estudios de lo señalado anteriormente, se optó por dividir la investigación en una parte teórica, llamada formulación de proyectos, en que se explica y analiza el ciclo de vida del proyecto poniendo especial énfasis en la etapa a nivel de perfil que cuenta con los siguientes módulos: Definición del proyecto, estudio de mercado, estudio técnico y evaluación de proyectos. La segunda parte de la investigación corresponde a la parte práctica, que cuenta con el desarrollo de un proyecto de infraestructura vial emplazado en la ciudad de Los Angeles, abordado solo a nivel de perfil, por tratarse de un proyecto social de pequeña envergadura.

Book Synopsis Biological Wastewater Treatment by : Mogens Henze
Download or read book Biological Wastewater Treatment written by Mogens Henze and published by IWA Publishing (International Water Assoc). This book was released on 1881 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.
Book Synopsis Sustainable Tourism? by : Gerda K. Priestley
Download or read book Sustainable Tourism? written by Gerda K. Priestley and published by . This book was released on 1996 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although widely advocated, sustainable tourism is subject to numerous interpretations -- from environmentally friendly forms of tourism to maintaining the economic viability of tourist activity in a specific place. This book explores various views on sustainable tourism and demonstrates its complexity and diversity, in order to clarify the issues in operational terms. It addresses questions such as: can tourist activity be sustainable economically; can tourism lead to sustainability from an environmental perspective; and what is the role of tourism as a sustainable development strategy? Much of the book consists of a series of European case studies, from the U.K., France, Spain, Italy and Greece. These case studies cover three main themes: recreation and tourism in natural and rural areas; coastal tourism; and islands. The book represents a valuable supplementary text for students of tourism, as well as related disciplines such as geography, economics, environmental management, and local and regional planning and development.

Book excerpt: The idea of finding a 'third way' in politics has been widely discussed over recent months - not only in the UK, but in the US, Continental Europe and Latin America. But what is the third way? Supporters of the notion haven't been able to agree, and critics deny the possibility altogether. Anthony Giddens shows that developing a third way is not only a possibility but a necessity in modern politics.
