Marina Martín Garcia
No full textIsla Martín Garcia is founded on a rock outcrop in the Río de la Plata which is a natural protected area between Argentina and Uruguay. Due to the extension of the runway at the local airport, wetlands between Isla Timoteo Domínguez and Isla Martín Garcia developed during the last decades. The bay, where the old port was located, was loaded with sediment. After the waters between the two islands sedimented, Isla Hércules is formed and a channel is created. For the location of the marina, three possible options are selected: at the pier, south of Isla Hércules and in the sedimented bay north of Isla Martín Garcia. By using a multi criteria analysis, a marina at the pier is chosen as the best option because of its small dredging area and minor environmental impact. In consultation with the consultative authorities, a marina at the bay is chosen as the elaborated alternative. The recovery of the old situation in which the marina is located in the bay is the main reason for this choice.Implementation of the marina at Isla Martín Garcia involves cooperation between two parties: the government and a second investor. The government is responsible for the island, and a certain amount of liquidity is required to boost tourism on the island. A second party, like a private investor, is introduced for the maintenance and exploration of the project. This cooperation needs to invest 22.9 million dollars; this includes the 16.4 million dollars for the government and 6.5 million dollars for the second party. Without involving an external investor the internal rate of return (IRR) is 1.77% which is very low. When involving a private investor the IRR increases, the external investor receives an IRR of 7.71 % over the entire lifetime of the marina.Hydraulic EngineeringCivil Engineering and Geoscience
Developing a framework for an ecosystem-based approach to sustainable marina development: Including a framework application case study for a marina on the island of Mauritius, Indian Ocean
No full textThis thesis report considers the topic of sustainable marina development. This term can be understood to be a combination of two terms; “sustainable development” and “marina”. Sustainable development in this research study has been considered in relation to the coastal zone and basically entails an approach to ensure a balance between the environment and economic development. A marina, being a coastal (economic) development, interacts with the environmental conditions of the coastal zone and as such, affects the balance for sustainable development. Sustainable marina development is subsequently defined as the development of a marina in such a way and capacity, that the marina integrates its natural, social and economic environment. Additionally, a marina cannot be deemed sustainable by itself, as important principles for sustainable development like the cumulative impacts, multiple (long-term) objectives and sustainability need to be considered on the level of the larger coastal zone, or ecosystem. Currently, marina design is considered to lack an integrated development approach, and is inadequately represented in current marina development guidelines. Especially the initial stages of marina development, involving important development considerations like location selection and alternatives evaluation, lack the assessment of a marina’s integration in its natural, social and economic environment; a key element of sustainable development.Civil Engineering and GeosciencesHydraulic Engineerin
Feasibility study for a marina at Hook of Holland - Zeejachthaven Hoek van Holland: Haalbaarheidsstudie
No full textThe distance between marinas along the Dutch coast is large. By building marinas on strategic locations along the coast, sailing times can be reduced significantly. However, building marinas bordering the North Sea is expensive due to the lack of sheltering from waves. Hook of Holland is such a strategic location, located at a distance of 30 kilometers of Stellendam and 20 kilometers away from Scheveningen. The realization of a marina at Hook of Holland will lead to season lengthening, differentiation of the beach function and creates a boost for the local economy. In addition, it will be a stepping stone for creation of a network of marinas along the Dutch coast which will enable day trips from marina to marina, boosting the economy further. Waves in the marina basin will lead to damage to the yachts if the significant wave height Hs is higher than Hs =0.6 m. The design storm for the marina has a return period of 200 years and will lead to waves with a significant wave height up to Hs = 4.3 m at the project area. Also it will lead to a water level rise up to 4.2 m above NAP. To reduce the waves in the basin, a large breakwater is needed which is expensive. An entrance of the marina along the Nieuwe Waterweg is cheaper but politically unachievable. A previous study for a marina with the entrance along the Nieuwe Waterweg did not make it to realization due to this factor. A marina is mostly financed with real estate development and funding of the government. Real estate development at the project area is difficult to realize due to the nearby Natura 2000 area ‘Solleveld & Kapittel duinen’ and its associated strict nature legislation . Land reclamation is a possibility to make real estate development possible. However at the moment this is not attractive due to the prices for land reclamation are higher than inland development of these functions. Also the real estate market is in a downward state due to the economic crisis. A marina at Hook of Holland needs to be on a small scale and well integrated in the surroundings without a large land reclamation project, such a marina will cost around 50 million euro. A marina at Hook of Holland is technically feasible and has a positive effect on the required coastal maintenance. However the direct revenues are much lower than the construction costs. The indirect revenues are significant, however without a public investment there will be no marina realized at Hook of Holland.Hydraulic EngineeringCivil Engineering and Geoscience
Culture Takeaway
Get PDFThis keynote is mainly based on Wallace's research for Volume X of La Cultura Italiana published by UTET in 2010. The volume is in Italian and, by translating it, it can now be shared with colleagues, students and friends. The relationship that each citizen has with his/her own country and culture is mediated by personal experiences and matured during a lifetime. It is a delicate task to identify what motivates the consciousness of “insiders” of a culture whilst, at the same time, stimulating the interest of outsiders. To be able to observe the prodigious artistic production of one’s own country from the point of view of another culture and another genetic material offers fresh cues. Curiosity, prodded by geographical and physical distance, helps to identify in a schematic way those characteristics that define a country’s visual culture in a decisively distinctive way
Metodologia para interoperabilidade BIM-FM baseada em base de dados relacional
No full textDissertação de mestrado em European Master in Building Information ModellingFacility Management (FM) activities frequently require continuous and reliable information of the asset inventory, condition, and performance. In view of that, BIM-FM methodologies present considerable advantages in regard to past conventional techniques, mainly because of improvements on commissioning and handover of facility data. Indeed, BIM-FM simplifies processes of data transfer and reduces errors, while allowing improvements on the possibilities of information management and operation of the asset. There is also a trend towards systematization of information in graphic format for a better visualisation of the assets performance, assisting O&M activities, and supporting an intelligent decision-making system. However, despite adoption of BIM-FM methodologies being in frank growth, it cannot yet be considered a widespread practice. One of the reasons that is hindering widespread application of BIM-FM is the lack of integration and interoperability issues between BIM platforms and FM systems. In many cases, this results on inefficient data management, when dealing with incomplete or inaccurate information in BIM models (at handover stage), requiring significant human labour to gather and input missing information into FM system. To address those challenges, this research proposes a BIM-FM oriented framework focused on establishing a bi-directional connection between the BIM model and a SQL format database. The dissertation further explores advanced and interactive data analysis possibilities using Power BI for leveraging the use of available data at the stage of operation of an asset. Detailed process maps are proposed to clearly define the operation of the framework in the wider scenario of a BIM-process, and also at the software interoperability level. The implementation and application of the proposed framework to a case study of the light fixtures of the library building at the Campus of Azurém of the University of Minho, allowed demonstrating the functionality and possibilities of the developments proposed. Overall, the framework goal is for an interoperability solution connecting the BIM model to a relational database with data that serves for FM purposes. Proposing the data analysis with the aim to support intelligent decision making and improvements on the assets’ performance. Thus, the proposed workflow is expandable and scalable to be applicable to any type of facility and its elements.As atividades relacionadas a gestão de facilidades (FM) dependem de informação continua e confiável sobre o inventário, condições e desempenho de ativos. Em vista disso, a metodologia BIM-FM apresenta consideráveis vantagens em relação a processos tradicionais, principalmente devido a melhorias associadas ao comissionamento e entrega dos dados da instalação. De fato, o BIM-FM simplifica processos do que diz respeito a transferência de dados e na redução de erros, enquanto melhora as possibilidades de gestão da informação e operação dos ativos. Existe também a tendência para sistematização de dados em forma gráfica, gerando assim uma melhor visualização do desempenho dos ativos, auxiliando as atividades de operação e manutenção da facilidade, o que serve de apoio a um sistema inteligente de tomada de decisões. No entanto, apesar da implementação de metodologias BIM-FM estarem em crescimento, não pode ser considerada uma prática difundida. Uma das razões que dificultam uma maior adoção de BIM-FM na indústria, tem relação com a falta de integração da informação e problemas de interoperabilidade entre plataformas BIM e sistemas FM. Em muitos casos isso resulta numa gestão ineficiente de dados, pois lida com informações incompletas e imprecisas dos modelos BIM (na fase de entrega), requerendo trabalho manual para coletar e inserir o restante da informação no sistema FM. Para abordar esses desafios, essa dissertação propõe uma estrutura de trabalho focada em estabelecer uma conexão bidirecional entre o modelo BIM e uma base de dados em formato SQL. A dissertação também explora possibilidades para a análise de dados de forma avançada com o uso do software Power BI, para uso dos dados disponíveis durante a operação de ativos de forma inteligente e interativa. É proposto um mapa de processos detalhado para definir as operações da estrutura de trabalho num cenário de aplicação mais amplo dentro dos processos BIM, incluso a nível interoperabilidade de software. A implementação de aplicação da estrutura de trabalho proposta no estudo de caso é para equipamentos de iluminação do edifício da biblioteca, no Campus de Azurém da Universidade do Minho, que permite demonstrar a funcionalidade e as possibilidades do desenvolvimento proposto. Sendo o objetivo de o fluxo de trabalho proposto demonstrar uma solução para a interoperabilidade entre sistemas, que conecta informações do modelo BIM a uma base de dados relacional, com o propósito de ser utilizado durante a fase de gestão do ativo. Por fim, apresenta a análise de dados com o intuito de apoiar melhorias no desempenho das instalações. Portanto, o fluxo de trabalho proposto é escalável e expansível, e oferece soluções para sistemas mais complexos e outras atividades relacionadas a gestão dos ativos
