Partners on a heavy haul road project at Dry Fork Station, Wyoming, US, saved on material, shipping and assembly costs with Big R’s Super•Cor Arch and the Vist-A-Walls.
Dry Fork Station is a 422-megawatt coal-power plant, owned by Basin Electric Power Cooperative and the Wyoming Municipal Power Agency. The heavy haul road required a stream crossing in a sensitive wetland area.
The inlet side of the stream crossing was large, which made Vist-A-Walls more economical in both materials and construction for its headwall. The outlet side was smaller, bringing it into a suitable scale for a sheet pile headwall.
The Super•Cor structure took exactly two days to erect and the Vist-A-Wall MSE Structural Wall System took about a week to erect and back fill. The sheet pile headwall was completed in two days.
The design allowed for minimal impact on the stream and surrounding wetlands.
The Ames Construction team leader commented that Super•Cor was the easiest crossing structure his crew had ever put together.
