INDIAN RIVER COUNTY, FLORIDA MEMORANDUM CONSENT TO: THROUGH: FROM: Joseph A. Baird, County Administrator Christopher R. Mora, P.E., Public Works Director C""-, Richard B. Szpyrka P.E., Assistant Public Works Director SUBJECT: Gifford Neighborhood 45th Street Beautification Project Change Order No. 1- Pipe Replacement IRC Project No. 1506 DATE: November 16, 2015 DESCRIPTION AND CONDITIONS On July 7, 2015 the Board of County Commissioners approved the award of Bid No. 2015040 in the amount of $1,306,877.14 to Sunshine Land Design, Inc., for the 45th Street Beautification Project. The project consists of the milling and resurfacing of 45th Street from 43rd Avenue to east of 24th Avenue, the construction of new five-foot wide paved shoulders, a westbound right turn lane at 28th Court, 2,700 LF of new sidewalk, existing sidewalk enhancements, curb and gutter, pavement markings, and extensive landscape improvements. On September 21, 2015 a metal stormwater pipe crossing 45th Street failed during a heavy rain event. Upon inspection of the pipe it was determined that the entire pipe across the roadway was failing and needed replacement. Review/inspection of the remaining ten stormwater pipes that cross 45th Street between 43rd Avenue and the FEC Railroad revealed that five of those crossings are metal pipes that have deteriorated to the point that they are also in need of replacement. Staff is of the opinion that the metal pipes and associated stormwater structures should be replaced before the resurfacing of the roadway. Sunshine Land Design, Inc., has provided an estimated cost of $313,783.32 to replace the failing metal stormwater pipes with concrete pipes and to replace associated stormwater structures. The work to be performed will require an additional 65 days of contract time. The estimated cost includes $72,612.38 for contingency line items for the replacement of the existing asbestos water line that crosses the existing stormwater pipe at the five locations identified and for the possible installation of line stops to control the water system during the water line replacement. At this time, it is unknown if the existing water line will need to be replaced or if line stops will need to be installed.
