Abstract
As one of the most popular cruise ship destinations in Alaska, the City of Ketchikan has had to evaluate their port structures and upgrade facilities to meet current load requirements. This paper presents the demolition, design, and construction challenges associated with the replacement of the Spruce Mill Dock. The project replaced a large portion of an aging timber dock with a new steel/concrete structure that meets current demand and code requirements. The design team met technical challenges presented by a short construction schedule, a remote project site, 7.6-meter (25-feet) tidal ranges, complex demolition requirements, limited availability of local high-quality high-strength concrete, a severely corrosive environment, difficulties during steel fabrication, and extreme weather conditions during construction. The cruise ship facilities are of critical economic importance to the City. Any miscalculation on the construction schedule that delayed the project completion date could have had severe adverse economic impact to the local businesses.
