BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
On June 4, 2019, the City Council approved the award of RFQ 17-220 to the Ciorba Group, Inc. to conduct the Phase 2 Design Engineering Services for the Downtown Washington Street Bridge Improvement project. The project scope includes the final design engineering services required to replace the three-span Washington Street Bridge with a two-span, post-tensioned bridge, as well as sanitary sewer, water main and electrical duct bank improvements. Ciorba's contract also includes providing technical support to the City throughout construction.
On March 2, 2021, and November 15, 2022, the City Council approved Change Order #1 and Change Order #2, respectively, for a total additional amount of $138,813.70. These Change Orders were necessary to compensate the consultant for providing additional utility relocation coordination and to account for significant project delays associated with right-of-way acquisition.
Change Order #3 was an administrative change to the agreement completion date as required by IDOT to ensure the project remains eligible for federal funding. This Change Order resulted in no additional costs.
DISCUSSION:
Change Order #4 is requested to compensate the Ciorba Group for providing additional technical support during the extended construction duration and for providing an alternative design for a retaining wall, which was necessary to minimize excavation and impacts to buried utilities. These additional services were beyond the control of Ciorba and not foreseeable at the time the CSA was executed.
