OBJECTIVE: To replace deteriorated corrugated metal pipes crossing underneath 17th Street SW and Keane Avenue.

of replacing the existing stormwater pipe underneath 17th Street SW and Keane Avenue, which will aid in conveying
stormwater flow through the C-2 North/South canal stormwater management system.
On August 27, 2024, County staff emailed the RFQ to all contractors under Agreement No. 20-7800 (the “Agreement”),
“Underground Contractor Services,” seeking quotes for the Project with a response deadline of September 12, 2024. On
September 12, 2024, staff reviewed the following three quotes received from: Mitchell & Stark Construction, Co, Inc.,
Coastal Site Development, LLC, and Quality Enterprises USA, Inc. The remaining contractors under the Agreement
