the Preliminary Measurement before the construction of line 2 of the Lima metro

The study consisted of a series of noise and vibration measurements at the exterior and at the foot of the dwellings to determine current levels.

The measurements have been focused on particular buildings considered to be sensitive (Parroquia de Carmen de la Legua, Palacio de Justicia and the water tower of  Sedapal).

Vibro-acoustic study for the Lima metro line 1

The study consisted of simulations with the software dBtrack ©and  the vibratory impact linked to the construction of a viaduct at the nearby hospital of Rocca Fernández Essalud.

This study included:

  • Measures to characterize the rolling stock
  • Measures of soil transmissibility
  • Measurements of vibration noise at the foot of the hospital Rocca Fernández Essalud and in front of the most sensitive devices
  • A simulation of the site
  • The search for solutions to reduce the impact of the future viaduct
