Enquiry
I am enquiring to obtain confirmation that DSM 5.50.85 is an acceptable noise barrier wall system for this MTO project 2014-3014. We have confirmed that the 5m offset restriction tied to DSM 5.50.85 is not applicable as the contract drawings show that the noise barrier wall exceeds 5m from the shoulder of the road. The specification calls for the DSM noise barrier wall type to be absorptive on one side. Please confirm that a noise study has been performed and provide confirming data that the noise barrier wall must be absorptive on one side. Based on the location of wall, it does support that the noise barrier wall must be absorptive on one side. Please confirm that DSM 5.50.85 is an acceptable noise barrier wall system for this MTO project 2014-3014. Your timely response is greatly appreciated.
