Quincy Reservoir is a 2,800 acre-foot raw water storage impoundment created by a zoned earthen embankment dam for the City of Aurora. The dam and spillway were constructed in the early 1970s. In 2006, damage identified by the State Engineer’s Office (SEO) to the spillway included spalling concrete, corrosion of reinforcing steel, and exposed waterstop.
Deere & Ault Consultants, Inc. performed site investigations and a feasibility study for repair options. Deere & Ault also prepared the final construction drawings, specifications, and construction cost estimate for the spillway repair. Construction work began in October 2012 and was completed in January 2013.
Deere & Ault provided part-time construction observation. A total of approximately 1,630 cubic yards of concrete was placed to repair the spillway. Additionally, 2,600 linear feet of underdrain pipes were inspected by video and repaired as necessary.
