Analysis
As part of the City’s ongoing Capital Improvements Program, wastewater locations in decaying condition are recommended for replacement by the Water Utilities staff on a yearly basis. The City contracted with an engineering consultant, RPS Group, to prepare plans and specifications to replace aged wastewater mains in various locations throughout the city with new wastewater mains. For this design package, six (6) locations were identified. On October 11, 2016, the City Council awarded this project to SYB Construction for the low bid amount of $2,604,696.50. Included as part of the contract award was a 5 percent contingency of $130,235.00 for project changes while under construction, which is typical for Capital Improvements projects.
The current Amendment/Change Order No. 5 in the net amount of $67,089.43 ($105,392.68 positive and $38,303.25 negative) provides for modifications in wastewater main installation method from trenchless to open-cut due to unforeseen conflict with an abandoned storm sewer culvert. This change order provides for the installation of 481 linear feet of 10” PVC sanitary sewer pipe by open-cut, it also provides for paving replacement and other related items of work.
Amendment/Change Order No. 4 provided for Time extension.
The current Amendment/Change Order No. 3 in the net amount of $41,384.62 ($286,836.12 positive and $245,451.50 negative) provides for modifications in wastewater main installation method from trenchless to open-cut due to unforeseeable conflicts during construction; it also provides for substantial completion of quantity overruns and underruns.
Amendment/Change Order No. 2 in the net amount of $166,791.55 provided for a change in the project scope and design for the wastewater line on NE 5th Street between High School Drive and Small Hill Street due to conflicts with existing utilities. The contractor attempted to construct the line as originally designed, but due to unforeseen conflicts with utilities, this location required a re-design to utilize other construction methods in order to alleviate the utility conflicts. This Amendment/Change Order No. 2 also provided for a change in the project scope and design for the wastewater line at the intersection of Corn Valley Rd. and Blueberry Ln. due to conflicts with existing utilities.
Amendment/Change Order No. 1 in the net amount of $177,970.09 provided for the re-construction of a 15-inch wastewater line under Turner Park which was not included in the original scope of the construction contract but was deemed in danger of an imminent failure and therefore required an emergency repair. Amendment/Change Order No. 1 included costs for constructing an 18-inch wastewater line in place of the existing 15-inch wastewater line via pipe bursting, investigation of the existing 15-inch line in Turner Park which was in poor condition, and quantity corrections for pipe rehabilitation and wastewater manholes.
City Staff recommends approval of Change Order Number 5.
The project completion date remains 1/31/2018.
