Boyette Road over Fish Hawk Creek Branch Replacement

« Return to Project Search

This project involved designing the replacement of a box culvert with a precast twin-cell box culvert after an inspection of the Boyette Road over Fish Hawk Creek Branch structure showed a 12.5-foot-long continuous void in the interior wall, starting at the junction with the floor slab that is 8 inches high and 12.5 feet long. It was determined that the intermediate wall was not structurally connected to the settling floor slab. Services included survey; geotechnical investigation; hydraulic analysis along with design or review of drainage features in the roadway plans, guardrail replacement, riprap rubble, and drainage cross sections; permitting; structural design for the replacement box culvert and wingwalls; utility coordination; preparation of roadway plans and drainage typical sections; and meetings.

This project was completed under a task work order-based contract with Hillsborough County to provide miscellaneous structural evaluations and repair designs, as well as other engineering services such as plans and report reviews for bridge designs and bridge hydraulics, preliminary engineering reports, scour evaluations, emergency evaluations, bridge replacement studies, and permitting. Ayres completed more than 50 structural and hydraulic reviews for the County under this contract.
