Terminal 18 North Crane Rail Upgrade Port of Seattle
HWA GeoSciences Inc. conducted a geotechnical investigation for the north crane rail upgrade at the Port of Seattle’s Terminal 18. The project consists of widening a 2,900-foot long section of the existing crane rail to accommodate larger (100-foot gage) cranes. The existing water-side crane beam will be reinforced, and additional piling driven to support the increased structural load. A new pile supported land-side crane rail beam will be constructed 100 feet west of the existing water-side rail, just behind the existing bulkhead. HWA performed a subsurface investigation consisting of several CPT soundings and exploratory borings to a maximum depth of about 200 feet, along the proposed land-side crane rail and off the edge of the apron to define subsurface conditions along the new outboard crane rail. HWA provided geotechnical design recommendations for crane foundation, piping, depth of embedment, and construction considerations.
