County: Bartholomew (IN) Existing Structure: 4’ Diameter CMP Replacement Structure: ALBC 9, 10’-7” span x 3’-5” rise, 31.1 sf opening, 45’ length Civilcon Solution: CivilCon supplied Bartholomew County with a complete replacement structure solution that included an aluminum box culvert with a full invert, toewalls, headwall and wing panels. The key feature for this project was the addition of a weir at the inlet to help the structure control the flow of water entering it. This alternative saved the county from having to place a very large structure in the location. CivilCon was also responsible for the assembly of the structure and necessary accessories. CivilCon completed the hydraulic and hydrologic analysis to ensure that the proposed structure’s performance would be sustainable to the conditions.
