HWC is providing design services for State Street in Veedersburg, Indiana. This project is comprised of milling and resurfacing the street, installation of new sidewalks and ADA-compliant curb ramps, new street and road culverts, closing two open ditches on the east end with new storm sewers, and re-grading where necessary to improve drainage, particularly on the south side of the street.
The existing twin metal pipe structure under SR 47 in Boone County was heavily deteriorated and regularly blocked with debris. HWC designed a replacement structure with a single-span box large enough to convey the required flows and debris to reduce maintenance efforts. A practical design approach avoided unnecessary waterway impacts that would have triggered mitigation and cost. The project design included completion of hydraulics, a Level 3 environmental document, and right-of-way engineering. Utility impacts and associated right-of-way needs were minimized by vertically adjusting the overhead utility to provide adequate working room under it for OSHA requirements. This minimized both the utility’s costs and INDOT’s cost. The construction cost was $325,000.
The existing 56” metal pipe arch culvert under SR 32 in Fountain County was heavily rusted and did not meet hydraulic backwater requirements. The replacement pipe is a 6’ diameter pipe, and the existing roadway met level 1 conditions. The shoulder and embankments at the pipe were transitioned at a 4:1 slope to provide additional clear space over the structure to improve safety. The project also included a level 2 environmental document and right-of-way reacquisition. There were no utility conflicts at this structure. The construction cost was $175,000.
The existing 56” metal pipe arch culvert under SR 32 in Fountain County was heavily rusted. HWC completed design of this spot improvement project including hydraulics and right-of-way acquisition. Two small pipes (CLV’s) were near this culvert and had failed as well. All three pipes were included in the project for replacement for more efficient use of a contractor’s mobilization to the area and project costs. Riprap requirements at the culvert outlet required additional right-of-way acquisition for the project. Overhead utility conflicts were avoided because the new pipes were lightweight and easy to install with smaller equipment. A buried utility was relocated beyond the new pipes. The construction cost was $230,000.
