Noise measurements during construction works for the replacement of the Rapphofsmühlenbach culvert No. 13 at WDK-km 28.460

01

The Waterways and Shipping Authority is procuring noise measurement services to accompany construction work for the replacement of the Rapphofsmühlenbach culvert No. 13 at waterway kilometre 28.460. The contractor must prepare a measurement programme defining measurement locations and the construction activities to be monitored, carry out noise measurements during the construction works, and document the results in expert reports. Without these measurements, the authority could face unchallenged and potentially unjustified claims. The authority has no staff available to carry out these services itself, so the work must be outsourced to an external contractor.
