13. What about the disturbances during construction?

While the laboratory is not likely to cause disturbance of any kind once it is commissioned, it is expected that there will be some disturbance during the construction stage.

The main source of disturbance, in terms of noise, will be during the initial stages of tunnel boring up to about 200 meters. This will be completed within 2 months after which noise pollution should subside almost completely. Advanced tunnelling methods may be used to further reduce the noise levels at the initial stages.

During construction the workers will be brought to the construction site. However, there will be vehicles in the ``staging area," which includes a small surface area as well as the area underground. This disturbance will be temporary and will cease after construction ends.
