Pre-Cast Reinforced Concrete Box and End Sections

This contract provides Sedgwick County with a two‑year supply agreement for pre‑cast reinforced concrete culvert boxes and matching end sections that meet ASTM C850 and KDOT standards. The County solicited bids from 60 vendors, evaluated them on a lowest‑price‑responsible basis, and awarded the contract to Wichita Concrete Pipe Co.
