BG Consultants provided platting and engineering design services for the Kansas Enterprise Industrial Park from the initial development of land. The industrial park originally included 196 acres divided into 14 industrial zoned lots. Another two lots, totaling 64 acres, were added at a later date. BG’s design provided for the extension and addition of streets (Enterprise Drive, Commerce Street, and Commerce Place); rail line extension and signals; and water, stormwater, and sanitary sewer utilities. The full scope of the project included over 10,000 feet of water lines, 6,250 feet of sewer lines, 3,300 feet of street design, 7,400 feet of storm sewer lines, and 10,900 feet of railroad improvements.
The roadway design included Commerce Place from Enterprise Drive to the south and terminating at a cul-de-sac. Site drainage was controlled by inlets and concrete storm sewer. The majority of the drainage begins at the cul-de-sac and is routed approximately 2,100 feet to a 6.5 acre-foot detention pond, which in-turn, drains into an existing drainage canal. The detention pond located at the southeast corner of the park also controls the drainage from the rail line.
A Rail Spur with a 7,200 foot extension of the Hutchinson Transportation short-line rail was designed, extending the line south and west. The location for the spur alignment was limited due to the existing site conditions. Wetlands mitigation was required to be utilized in the improvements and two stream crossings were constructed. The railroad crossing was constructed of two double 10x6 RFB and the Enterprise Drive crossing was constructed of two Double 8x8 RCBs. Also included in the rail design are 2 actuated signals and a turnout. The turnout allows access to the rail line from the 2 south lots of the park.
BG managed this project by providing KDOT certified inspectors to oversee the construction. Construction observation included inspecting all work performed and materials furnished for the project. Weekly progress meetings between the City, contractor, and BG were held to keep an accurate account of construction activities. Materials inspection included density testing of the subgrade and crushed stone aggregate, reviewing shop drawing submittals with verification at the point of use, observing pressure testing of the waterline and sanitary sewer and measurements of quantities. The documentation created throughout the construction process allowed BG to generate an accurate set of as-built plans for the City.
