Civil engineers have been present in the development of cities since the early years of our profession. Nowadays, is important to value the received legacy and to keep working in order to transform the contemporary cities into the cities of tomorrow. In this way, working in our traditional field, but, at the same time in new niche markets, in collaboration with other professions, civil engineers will keep providing innovative ideas for the cities and we will make our work distinct, recognized and appreciated.

The urban developments in North and Northwest Madrid were defined by the 1997 General Town Planning Scheme. Since the year 2000, 75 % of the 54,000 houses considered under the scheme have been completed. Different forecasts suggest saturation by the beginning of the next decade. This model, which left much to be desired in terms of urban characteristics, has finally reached the point of exhaustion.


Bikes are considered a secondary means of transportation and, consequently, the road-network-operators have never given them the desired and necessary importance. In recent times the use of the bicycle has increased both for recreational reasons and can be considered as a proven means of sustainable transportation. Unfortunately, an increase in the usage of bicycles has resulted in an increase in accidents. An example of this is the increase of bicycle accidents along the road-network of Diputación de Valencia. This article intends to highlight the presence of bicycles in a local road network and will examine the different typologies of cyclists that we find on our roads. Furthermore, the article will demonstrate the measures adopted by 'Diputación of Valencia' for the full integration of cyclists as transportation customers.


The Government of Spain should be driving the implementation of policies that prioritize economic growth, to create employment and promote social cohesion across the entire country. In this context, selective investment in improving accessibility of Spanish municipalities from local highways would be a programme meeting the maximum number of required conditions: • Local highways are a basic element of social policy. • Local highways still continue to present the highest accident rates. • Investment in local highways generates a fiscal return to the State in excess of 50%.

Very little has changed with respect to water matters over the last forty years. The same roles have been taken over by different individuals. There has been no change. The call for solidarity between regions for the distribution of water goes against the proclamation of the European Water Charter that "Water knows no boundaries". In Spain the failure of water proposals is largely down to the concessions granted by central government to the regional authorities, and invoking the precept of solidarity in vain. This failure in Spain is all the more incongruous as this is an area when the full value of water has been well understood for over 100 years.


Recent hydrological planning, far from achieving a fair and sustainable distribution of water resources, has left Castilla-La Mancha submitted to some other regions' purely economic interests. Moreover, the environmental demands required by The EU Water Frame Directive have been set aside..


By tracing international architecture from the mid-20th century (and possibly even further back to the early 1900s) we may appreciate the collaboration between architects and engineers (essentially structural engineers) in the design and construction of the most significant works of architecture. The contribution of engineering in the search for ever lighter roof structures, the modification of earlier structural solutions and architectural proposals for structures at the very boundaries of knowledge, as manifested not only by space frames and suspended roofs, but also by the structural transformation of tall buildings, reveals an architecture heavily influenced by engineering. From the end of the sixties and when attempting to transmit this influence as a technological image of architecture, including the external image of the building systems, the accesses to the buildings and the structural glazing solutions, architecture has required the support of engineering more than ever in the search for innovative solutions at the service of architecture. In more recent times, and now in the present century, geometrical mannerism has dominated the image of architecture and the ever-present support of engineering has been brought to the aid of architecture to produce sometimes contradictory results between structural rationality and the formal image of buildings.

In ancients times the roles of these two master builders - engineers and architects-were merged into one. Over the course of time, these roles took different paths until separating into the two specialized professions we know today and where both take their respective part in construction design. However, the lines between the two professions are becoming ever more blurred by the increasing need to meet public requirements, not only with respect to basic infrastructural needs, but also in terms of their iconic image.


Much has been written about the person of Leonardo Torres Quevedo, who was fundamentally an inventor and one of the most brilliant ever to have emerged from Spain, and undoubtedly the most prolific of all. For this reason, we shall not study his biography nor the host of inventions he made in many different areas, nor the multitude of other activities he conducted throughout his life. We shall, instead, concentrate solely on his work as an inventor and builder of aerial lifts, of which plenty has also been written; but here we shall focus on the gondola type lift, his most attractive element.


Concrete pavements have certain qualities (low maintenance and high durability, stable and resistant surfaces, light colour, mitigation of heat-island effect, aesthetic possibilities, etc.) which make their use in road surfaces highly interesting. This paper analyses those benefits along with certain drawbacks which have tended to be attributed to this solution (length of time up to opening to traffic, acoustic properties, etc.) which can however be suitably addressed using the techniques currently available. It reviews the various types of concrete pavement, aspects to be considered in their design (such as thicknesses or joints) and the available construction methods. A detailed analysis is made of certain options as regards the finish of concrete pavements in which colouring, printing, texturing, retarded curing and other techniques allow us to achieve a great variety of decorative effects without sacrificing slip resistance. Finally it examines some properties of lean-mix concrete road bases, as widely used in road pavements in many cities.
