We will use acoustic software to simulate the noise level during construction.

proposal for noise mitigation
Our consultants will offer a propos including a design that will comply within the established noise regulations.

continuous survey
We will continue to monitor noise levels during construction at different locations.

post construction survey
Once the whole project is over, a survey will be conducted to assess post-noise levels, ensuring that they stay within regulations.
All reports will be in ISO standards.
