SUMMARY:
The development of the City's Transit -Oriented Development ("TOD") Packinghouse District requires upgrading the existing sewer line in Crowther Avenue to provide adequate capacity for all the new planned developments along Crowther Avenue. Dudek Corporation (Dudek) completed the design of the TOD Crowther Sewer Pipeline Project ("Project") and on November 16, 2021, City Council approved a construction contract with the low -bidder, Kana Pipeline Inc., and a contract with Dudek for providing engineering support services during the construction of the Project. Since the start of construction in January of this year, Dudek has been reviewing submittals, answering RFIs, reviewing schedules and change orders, in addition to resolving design and unforeseen construction issues.
After the Contractor conducted the initial potholing, as required by the contract, they discovered that the elevations at the point of connection to the Orange County Sanitation (OCSD) trunkline were different than the elevations that were obtained from the as -built plans provided by OCSD during the design phase. In addition, the area where the construction was to start at State College Boulevard was occupied and staged by other contractors working in the same area for the City of Fullerton. These contractors are working on major street improvements associated with new developments along Orangethorpe Avenue. As a result, Kana Pipeline had to change the sequence of construction and it became essential for Dudek to check and evaluate the plans to ensure that the original design would work with the existing elevations. The proposed agreement amendment in the not -to -exceed amount of $40,000 is necessary for Dudek to continue supporting the project and to handle any future construction issues.

RECOMMENDATION:
It is recommended that the City Council take the following actions:
1. Approve Amendment No. 1 to Professional Services Agreement with Dudek Corporation for an additional $40,000 to complete additional design work for a cumulative contract not - to -exceed amount of $72,255; and
2. Authorize the City Administrator and/or his designee to execute all the necessary documents, in a form approved by the City Attorney.
DISCUSSION:
The existing sewer line serving the Transit -Oriented Development (TOD) District requires upgrading to provide adequate sewer capacity for the new developments along Crowther Avenue.
Along with a construction contract to Kana Pipeline, on November 16, 2021, City Council also approved a contract with Dudek for providing engineering support services during the construction of the TOD Crowther Sewer Project. Dudek was the original designer for the TOD Crowther Sewer Pipeline Project. In addition to construction support services involving review of submittals, RFIs, reports and change order requests, Dudek has actively been resolving unforeseen conditions that the Contractor has encountered since the start of construction.
After the initial potholing for utilities, the contractor found that elevations at the point of connection, on State College Boulevard were different than the elevations shown on the original as -built plans that were provided to the City by OCSD during the design phase. Additional potholing was necessary to ensure that the original design would work with different elevations at the connection point. Dudek had to review and analyze the original design to ensure that the design of the new gravity sewer line would work with the new elevations. Another issue that was encountered at the start of the project was a conflict with ongoing construction work at the connection point to the OCSD's trunkline. As a result, Kana Pipeline could not start their construction at the planned location and had to revise their original plan, starting upstream from the original connection point.
Dudek had to perform design evaluations to ensure that the new phasing plan would work with the new elevations that were obtained using the potholing information.
This proposed amendment will provide additional funding for Dudek to continue with engineering support services and to assist with performing necessary design evaluations and resolving any unforeseen construction issues for the balance of the project.
FISCAL IMPACT:
The recommended actions will approve Amendment No. 1 to the Professional Services Agreement with Dudek increasing the contract amount by $40,000.00, for a cumulative not -to - exceed the contract amount of $72,255.00. The total project budget including the ARPA funds and the TOD Sewer Development Impact Fees will cover the cost and no General Fund dollars have been allocated to this project. As such, sufficient funds exist for the recommended actions.
