WSP Air Quality, Noise, Vibration and Acoustic Services

Amtrak B&P Frederick Douglas Rail Tunnel Replacement, Maryland Performed an updated community noise and vibration impact analysis to evaluate changes in the design of the B&P Tunnel for the purposes of determining suitable real estate subsurface easement compensation for residences above the

tunnel. Construction noise and vibration levels, as well as future operational noise and vibration levels, were all evaluated in accordance with FTA/ FRA guidelines. The Cadna-A model was used to predict noise levels, and FTA and WSP spreadsheet models were used to predict vibration levels. The results were presented to Amtrak to allow them to determine any momentary compensations. WSP also developed the project’s construction noise and vibration specifications, particularly with regard to potentially impacted historic properties.

Micron Chip Manufacturing Plant, New York This noise study focuses on determining construction noise exposure over a 20-year, four-chip fabrication plant

construction phase. We are completing the traffic noise and construction noise studies requiring both Cadna-A and TNM modeling. Assessment is being completed using NYSDEC, New York State DOT and Town of Clay noise criteria, as well as FTA construction noise and vibration criteria.
