RECENT PROJECTS

WADOE – 2014 CORNET BAY REMEDIATION
In 2014 Glacier completed the upland remediation of the Cornet Bay Marina. An earthquake severed fuel lines supplying gasoline and diesel fuels to the dock fueling stations years ago, which contaminated most of the marina area with fuel product. To facilitate the excavation and removal of the contaminated material to the depths required, the existing marina store was moved temporarily, and following excavation relocated onto a new concrete foundation. Glacier removed, transported and disposed approximately 23,000 tons of contaminated soil and imported and placed a similar quantity of backfill.

In addition to mass excavation, a new steel sheet pile bulkhead was installed and finished with a concrete sidewalk/bulkhead cap and new stainless steel railing. Other site improvements included replaced utilities, new double walled fuel lines with leak detection, concrete patios, and improvements to the marina store. This project presented unique challenges working on the shoreline with fluctuating groundwater levels, a strict schedule of work that needed to be complete within the fish-window, and maintaining access to the public accessing the marina during construction.

SEATTLE CITY LIGHT – 1250 DENNY WAY DEMOLITION & EXCAVATION (2012-2014)
Glacier was contracted by Seattle City Light in 2012 to complete the demolition and remedial excavation of the Former Greyhound Bus Maintenance Facility in Seattle. The property operated as a bus maintenance facility for more than 60 years.

This Project was completed during two construction seasons in 2012 and 2013. The first season included abatement and demolition of all existing buildings, building foundations and off-site disposal or recycling of the demolition debris. 2013 work included demolition of surface pavements and street improvements overlying the work, excavation of contaminated soil, and backfilling and restoration of the site. Excavation depths (up to 32 feet below exiting ground surface) necessitated installation a soldier pile wall almost completely surrounding the site. Glacier exported over 103,000 tons from the site and imported over 90,000 tons of borrow material. Restoration work included installation of a storm water detention system, replacing an 8-inch City water main, and replacing all disturbed rights-of-way with new asphalt and sidewalks.
