success story CalPortland Slip Form Success Pouring for United Grain on the Columbia River Dave Frentress W ater transportation of bulk materials is a common sight in the northwest. Despite being 80 miles from the ocean and the Oregon Coast, with its location along the Columbia and Willamette rivers, the Portland/Vancouver area is a hub of shipping activity. Operating a cement terminal, aggregate operations and ready mix plants located along these waterways, NRMCA member CalPortland utilizes water transportation for concrete materials. These locations make CalPortland a prime supplier for many of the large grain storage and shipment facilities being constructed along the Columbia River, contributing further to the company’s expertise in supplying concrete to large slip form pours. Located along the north side of the Columbia River in Vancouver, Wash., United 14 ı SPRING 2013 Grain’s export terminal handles shipments of grain, soybeans and corn that move through the Port of Vancouver. United Grain operates from facilities that were originally constructed with concrete in 1935 (attesting to concrete’s durability). Recently, United Grain contracted Younglove Construction, based in Sioux City, Iowa, to construct a $72 million expansion, consisting of a cleaning tower that is more than 300 feet high (which allows for cleaning and storing enough grain to fill an entire ship) as well as 26 new silos, each 35 feet in diameter and 125 feet tall. In Proximity The new silos have added 66,000 metric tons of storage to the facility. Younglove Construction selected CalPortland to supply its concrete needs for the project. One large advantage to Younglove was that CalPortland’s West Vancouver Plant was located less than a mile from the project. The West Plant is one of three high-production “wet” plants that CalPortland operates in the Portland/Southwest Washington area. Another advantage was CalPortland’s ability to secure Transportation Worker Identification Credential (TWIC) cards for drivers and other support people on site (such as QC staff and mechanics). Because the project site was within the secure area of the port as established under Homeland Security guidelines, site access was prohibited without a TWIC card or an escort.
