The Project: The MacArthur Interchange improvement project will help relieve traffic in one of the most congested areas of US-90 in New Orleans. The highway is important to the offshore petroleum industry, as it connects the cities of Lafayette and New Orleans to port cities along the coast. The Challenge: One of the products for the project is a 72" U-Beam with an unusual void configuration and multiple void lengths at variable positions within the beam. The Solution: The base form was a one-piece vessel type form designed for partial self- stressing to accommodate strand located at the top and two intermediate locations. The void configuration required the voids to collapse to strip product. Because there was a small quantity of beams to cast, the voids were built in sections that manually unbolt to dismantle the center core for stripping. The center voids were built at different lengths that could be bolted together to create multiple assemblies. The end voids included three 2-foot fillers that could be removed to cast different length end voids. Two-piece trapezoidal headers were supplied to create a dap at the end of the beams. When you next project calls for a custom solution, call on Hamilton Form, 817-590-2111 or Hamilton Form Company, Ltd. 7009 Midway Road • Fort Worth, Texas 76118 "Considering the complexities involved in the forming, the success we have had during production is because of all the forethought that went into form design." Andrew Levens, P.E. Chief Engineer Gulf Coast Pre-Stress, Inc.
