The change order addresses differing subsurface conditions, duct bank conflicts, and includes a credit for concrete manhole substitution. The decision was adopted on 7/21/2026. The project is located in Commission District 2, represented by Commissioner Marleine Bastien. The project originated from Resolution No. R-597-13 to extend sanitary sewer service to commercial and industrial parcels within the Miami-Dade Green Technology Corridor (GTC), and is part of the Connect 2 Protect Program. The project includes approximately 9,246 linear feet of sanitary sewer mains and 9,851 LF of ductile iron water main service lines.

After the change order, the Substantial Completion Date is revised to February 15, 2027 and the Final Completion Date to March 17, 2027.
