During the construction of Line 5 of the São Paulo Metro, we had the privilege of carrying out an impressive test at LAEDE on a full-size prototype of the permanent track of this line. This slab, 14 meters long and weighing a surprising 40 tons, was built inside our laboratory for a unique experiment.

The video below shows the moment when the prototype passes through the natural frequency and enters resonance when subjected to Vibrodina. It is surprising that a slab with such dimensions and weight can move in such a way.

The objective of the test was to confirm the efficiency of the vibration attenuation system to mitigate the impacts produced by the passage of trains on the magnetic resonance equipment of the Hospital São Paulo, located very close to the track.

This world-first system was conceived and designed by IEME Brazil with devices custom-made by Vibtech.

This is yet another example of IEME and LAEDE’s commitment to technological innovation and engineering excellence. This is how we transform challenges into high-impact solutions for Brazil and the world!

Urban accessibility is a fundamental issue for the democratization of the right to come and go in cities. This is a set of measures aimed at ensuring that all people, regardless of their physical conditions, have equal opportunities to use public and private spaces autonomously and safely. Although it is a right guaranteed by law, much progress still needs to be made in its effective implementation.

An accessible project encompasses several aspects that are essential to ensure the inclusion and mobility of all. One of the key points is the adaptation of urban infrastructure, including sidewalks, public roads, squares and buildings, to make them accessible to people with reduced mobility, such as the elderly, people with physical disabilities or people with strollers. This includes removing architectural barriers, creating access ramps, installing handrails and adapting elevators.

Rotas Acessíveis

With the aim of creating an even more integrated city, projects such as Rotas Acessíveis were born. The proposal is to create routes based on the need to travel between public transport stations and points of interest for people with disabilities or reduced mobility. Examples of these points would be: hospitals, public services, schools, colleges, malls, theaters, parks, among others.

In São Paulo, the Rotas Acessíveis pilot project included 6 routes: Vila Clementino, Barra Funda, Marechal Deodoro, Ipiranga, Linha Azul and Centro and are currently present in the 2021-2024 Plan of Goals of the City of São Paulo. They also gained space in the Vida Segura Plan, established by Decree 58717/2019, with projects that must be based on accessibility standards.

IEME Brasil actively participated in the creation of Rotas Acessíveis in São Paulo, joining strategic points in the city, integrated by adapted transport, sidewalks and accessible places. The mapping of regions, carried out by IEME, was the basis for defining accessible routes in the municipality, considering important points, interference, transport and inclinations of the routes.
