subway

The construction of metro lines is one of the metropolitan transport infrastructures that contribute to facilitating connectivity and developing cities’ economic, social and leisure activities.

These underground arterial networks undoubtedly have significant benefits for urban life. At the same time, they face significant challenges for the future However, it requires complex execution to enjoy it Metro works affect the nerve centre of cities; however, they improve mobility and urban structuring by providing a fast and efficient way to move around the city, shortening travel times. In addition to reducing pollution levels, by reducing the number of vehicles on the road,

The planning and design of these suburban lines are crucial for the metro line construction project’s success and subsequent maintenance. The precept under which this type of metro infrastructure projects and works are already being undertaken is mainly that of service, taking into account criteria of usability, comfort, quality, safety, accessibility and response to needs.

Maintaining subway lines that serve thousands of passengers daily requires a specific preventive maintenance plan. Sando Conservación y Energía first performs routine preventive maintenance (cleaning drainage components, conducting geometric inspections of the infrastructure, tightening fasteners, lubricating components, etc.), as well as routine and non-routine corrective maintenance on the infrastructure, architecture, and tracks of the metro.

Growth and smart metro

The growth of cities and the need for both radial and circular interconnection with the peripheral rings and each other pose significant challenges for conventional metro infrastructures in terms of renovation, extension and adaptation of the existing network and the planned routes.

In some cities, implementing a light rail model is being pursued to improve mobility and reduce the cost of building metro lines. This change favours the reordering of city centres around pedestrians, eliminating private vehicles from central areas as much as possible and promoting public transport.

The smart metro is being implemented gradually. Sando Infraestructuras y Proyectos applies technology to its new projects that enables the digitization of infrastructure and services, paving the way for a smart metro system. In this regard, it has extensive experience constructing conventional and light metro lines in the centres of several cities such as Malaga, Seville and Madrid. Sando Infraestructuras y Proyectos and Sando Conservación y Energía have highly trained staff capable of handling complex projects involving the construction and maintenance of subway lines in city centers.
