Morrison-Maierle Receives Three Engineering Excellence Awards
The Montana Chapter of the American Council of Engineering Companies (ACEC) awarded Morrison-Maierle with three 2022 Engineering Excellence Awards. This included awards for projects in the structural systems, waste and storm water, and special projects categories.
The MDT MT-81 Bridges project received the Structural Systems Honor Award. The Montana Department of Transportation (MDT) hired Morrison- Maierle and Frontier West to replace three bridges along Montana Highway 81 (MT-81) between Fort Benton and Lewistown. The original structures were constructed in 1934 and 1948 and had begun to deteriorate. The new structures were designed and replaced with one phased concrete box culvert, one phased single span bulb-tee structure, and one single span steel girder bridge with lateral slide construction. All were completed in one construction season.
In the Waste and Storm Water category, Morrison-Maierle received top honors for the Four Corners Wastewater Treatment Plant. The Four Corners County Water and Sewer District needed to construct a larger wastewater reclamation facility to serve the rapidly growing Four Corners area west of Bozeman, Montana. The district hired Morrison-Maierle to plan, design, and construct the new facility. Morrison-Maierle helped manage every aspect of the project including planning and site selection, evaluation and selection of funding options, preliminary and final engineering, and construction administration and materials testing. To reduce the initial financial burden on existing customers, the facility was designed to expand in phases as funding from new developments becomes available.
Morrison-Maierle designed a solution for the Billings Interceptor project to win the Special Projects Honor Award. Morrison- Maierle designed a 4,735 linear-foot trenchless rehabilitation solution for this busy area’s 60-inch sanitary sewer interceptor main. Instead of tearing up streets, railroads, and pedestrian walkways to replace the whole pipe, they used the cured-in-place pipe (CIPP) method to avoid open cut excavation as the project went through downtown, the railroad right-of-way, Highway 87, and a state superfund site. The project team also lined 13 manholes with a polyurea liner to avoid the costly replacement of large tee and box manhole structures.
