Waterfront Development for New Cement Plant

A cement manufacturing plant located with access to deep navigable water has economical advantages and marketing potential for its product. The site of Ideal Cement Company's new Seattle, Washington Plant was small and not located adjacent to raw materials, therefore, economical transportation and handling of materials was essential. A waterfront bulkhead consisting of 17 steel sheet pile circular cells and connecting arcs was provided with a bulkhead height of 50.5-ft. The waterfront bulkhead, retaining the site adjacent to the Duwamish Waterway for a distance of 1,100-ft allowing maximum utilization of the property, is subject to the surcharge loads of a 70,000 ton windrow raw material storage adjacent to the waterfront and a 750 tph capacity traveling barge unloading tower crane located over the cells. It also serves as a dock with a fender system and mooring devices on the water side of the bulkhead. The waterfront design considerations, descriptions, and construction are briefly reviewed.
