January Update on the Mukilteo Multimodal Terminal Project

From WSDOT: In-water work continues on the Mukilteo Multimodal Terminal Project as Manson Construction continues work on the wingwalls. Crews need extremely low tides for extended periods of time so they can weld in locations that are normally below the water line. These extreme low tides occur between the hours of 6:00 PM and 4:00 AM. To take advantage of these tides, crews will extend nighttime work for an additional 18 nights through February 15, 2020, when the fish migration window closes and in-water work is prohibited. The City of Mukilteo has approved a noise variance for this work.

What To Expect During Nighttime Work

Manson Construction Crane Mukilteo Multimodal Terminal Jan 2020

Nearby neighbors may see and hear welding operations, hand tools, small power tools and the engine of the derrick crane. Sound will dissipate as it moves away from the terminal.  Also, the terminal sits between the working location and the homes that overlook the new terminal.  Noise is 70 – 80 decibels (equivalent to a passing car or bus) at the source. The sound will dissipate to 7 – 25 decibels (equivalent to rustling leaves) for neighbors 600 to 1500 feet away. Crews will shut off all equipment when not in use to minimize noise. There will be no work on Sundays or holidays.

Crews will also do pile driving on Saturday, January 25, which is within the normal permitted working hours, but notable because crews don’t generally work on Saturday.
