PROJECT OBJECTIVE

Improved mobility

The Barcelona City Council through its infrastructure company BIMSA begins the construction of the road underpass in Plaza de Glories. This infrastructure will improve mobility in a place of transport centralization and high traffic. For this purpose, the construction of underpasses with a North-South orientation is being carried out, divided into 4 lots.

These underpasses will cross other critical infrastructure such as commuter train lines. This crossing creates a delicate situation in an infrastructure that is in use by thousands of users.

How we made it happen

Monitoring system

BIMSA, through Eurogeotécnica, commissioned us to install a monitoring system to record possible impacts of new works on existing infrastructures.

To protect the existing tunnels, a battery of 1.1-meter diameter horizontal metal tubes was installed to limit deformations and act as a shield during the lower works.

We implemented an innovative structural deformation monitoring methodology by installing 4 SAA accelerometer arrays on existing inclinometer tubes, which were previously only used for manual measurements. Two 55-meter and two 32-meter arrays were installed.

We take care of the supply, installation, configuration of the system and sending data to the client for integration into the monitoring platform.

RESULTS AND ACHIEVEMENTS

Deformation analysis

We implemented a continuous monitoring system that made it possible to analyze the evolution of deformations in the slabs of the railway infrastructure during the construction of the tunnel, with measurements every meter in four cross sections.

The frequency of data acquisition was configurable, and the system proved to be reliable in minimizing risks to other infrastructure during construction.
