The reshaping of civil engineering education and training has been found to enhance student performance and improve their skills when facing the challenges of the real world. The industry is asking for engineers with better communication and teamwork skills, and most importantly, a broader understanding of how to solve real working market problems and create value in the marketplace. Moreover, the professional research institutions throughout the world and particularly in Portugal, such as engineering schools, are beginning to integrate entrepreneurship and business concepts into their training options.The present paper intends to present an overview about the challenges for maintenance and asset management, education and training of future generations and reshaping of research institutions. Moreover, a proposal is presented for the reshaping of maintenance and asset management education and training considering Portugal´s needs. Additionally, the development of new approaches is presented, as well as a proposal for reshaping maintenance and asset management education and training: roadmap for Portugal needs. The main conclusions of the paper are also stated.

Maintenance and Asset Management are very important for the Architecture, Engineering, Construction and Operation (AECO) sector. The increase in associated information makes necessary to have greater control of it, with the emergence of Construction Information Classification Systems (CICS), which are fundamental in the classification of information and its use. The built environment is vulnerable to risks that are impossible to eliminate, and this prompts the need for managing and classifying the resilience and sustainability of different constructed assets.This paper presents contributes to a discussion on the ways to measure the resilience and sustainability of built assets, namely based on rating systems composed by different dimensions, several indicators and parameters. It covers not only the building's intrinsic qualities, but also its interdependence with the community, surroundings, and users in the context.

Resilience evaluation systems have been used to aggregate and calibrate multi-dimensional resilience-related inputs. But these evaluation systems do not offer comprehensive outputs nor sufficient analytical capacity to support the design and implementation of city and community recovery and resilience plans. Urban resilience research covers multiple fields of study like earthquakes, floods, and tsunamis, amongst other types of disaster risks. This study focuses on the strategic needs of resilience and recovery plans for Portuguese cities and communities and proposes a sophisticated mapping system to address this gap. The main output of the proposed approach is a multi-layer heatmaps with scores based on various disastersfor all Portuguese cities. The resilience score is obtained through real statistical geo-data analysis.

A segurança das pessoas e o elevado valor dos bens construídos e dos seus conteúdos, bem como a sua criticidade na satisfação das necessidades básicas e bem-estar das comunidades, sempre suscitaram preocupações quanto à sustentabilidade, resiliência e fiabilidade do ambiente construído. A resiliência dos ativos construídos está frequentemente ligada à formulação de políticas e estratégias para o ambiente construído após eventos catastróficos ou traumáticos. É um conceito multidimensional que abrange aspetos físicos, infra-estruturais, ambientais, económico-sociais, regulamentares e organizacionais. O presente artigo apresenta os resultados da aplicação de um sistema de classificação de resiliência assente numa abordagem holística, abrangente e sistemática, a diferentes tipos de edifícios, em qualquer fase do seu ciclo de vida. Em particular, analisa a resiliência de edifícios de escolas públicas portuguesas a diferentes riscos do ponto de vista da engenharia, nomeadamente no que diz respeito à segurança estrutural e de manutenção do edifício. Os edifícios escolares analisados, construídos ao longo do século XX, tiveram intervenções alargadas, entre 2009 e 2011, no âmbito de um programa nacional de investimento público. Os edifícios foram analisados antes e após intervenções de reabilitação. Relativamente a indicadores económicos e a investimento potencial, nota-se que as intervenções de reabilitação apresentam impacto positivo na classificação da resiliência.

Transport infrastructures such as roads, railways and runways are under increased traffic loading and their rehabilitation has to be performed in an efficient way, structurally and financially. In this process, monitoring of structural and functional capacity of transport infrastructures using nondestructive tests is performed in a systematic way. It is important to take advantages of these measurements to plan a future rehabilitation.Using the BIM methodology, it is possible to obtain a model that, besides containing the three-dimensional graphic representation of the pavement or rail track and its physical and mechanical characteristics, also has information regarding the structural condition resulting from the continuous inspections.The authors developed case studies of Building Information Modelling (BIM) applied to roads, runways, and railways. In the road and airport pavements cases, the integration of structural capacity in the modelling was studied. Regarding the railway

The recognition of the high costs of the vulnerabilities of cities and communities due to various types of disaster risks have helped build the business case for improving the investments of the quality and resilience of buildings and civil engineering works. This important issue has attracted the attention of several stakeholders, including engineering professionals from different fields, scientists, standardization bodies, investors and financial institutions, regulatory agencies, user groups of several, as well as administrative services at national and regional level.This paper discusses the application of a resilience rating system to show the impacts of capital investment in building refurbishment and renewal. It highlights aspects in building renovation programs that efficiently and quickly increase their resilience in face of extreme events. The work presented builds on previousdiscussions on ways to measure the resilience of built assets, namely based on a rating system composed by different dimensions, several indicators, and parameters. It covers not only the building's intrinsic qualities, but also its interdependence with the community, surroundings, and users in the post-disaster context.

The real-estate valuation is still complex when it comes to the quantification of the areas and all the factors and coefficients involved in the tax asset value calculation. Automatic methods developed for this purpose have been using various possible approaches and tend to be quite complex for the calculation speed required in most cases. Building Information Modeling (BIM) has as its main advantage the possibility of a precise representation of the geometry of building elements, with integration of information and data in several dimensions. In this sense, this work intends to show the interests that exist in the creation and use of the BIM three-dimensional digital model, providing evidence of the value created for owners, designers, and investors through its use, creating better quality projects and more efficient construction processes, with economy of time and money. The present research work aims to develop the use of an automatic method for the real-estate value calculation, using BIM methodologies. Through BIM, the Architecture, Engineering, Construction, and Operation (AECO) sector can take major evolutions in process optimization, following other major industries. These concepts allow for great speed and efficiency in post-project phases with many advantages compared to current methods. In the scope of the work, an automatic method is developed to calculate the real-estate value in two case studies. The application of the automatic method gains even more importance due to the possibility of its implementation in any developed three-dimensional model. Finally, the results obtained are analyzed and the main conclusions stated.

No final, descrevem-se modelos de análise do comportamento dos edifícios e a sua aplicação na determinação dos assentamentos admissíveis em edifícios com diferentes soluções construtivas.

No presente estudo faz-se uma abordagem geral sobre a problemática dos pavimentos térreos em edifícios industriais, procurando-se desenvolver aspetos essenciais sobre o solo de fundação e sua interação com o pavimento, dimensionamento e processos construtivos. O estudo pretende restringir-se fundamentalmente a pavimentos constituídos por lajes de betão fracamente armadas e localizadas no interior de edifícios industriais, embora se possa generalizar a outras situações.

O que se procura realizar no presente estudo/livro é uma reflexão prática e sistematizada sobre um extenso quadro de qualificação residencial, que harmonize sistematicamente e na medida do que se considera ser possível, a perspetiva da satisfação dos habitantes com os aspetos associados à qualificação da própria conceção arquitetónica, considerando nesta os respetivos aspetos de desenho urbano. Visam-se, assim, neste livro ideias e caminhos de investigação sobre a relação profunda que existe entre a qualidade da Habitação
