PRIOR BOARD ACTIONS:
1) March 15, 2021, Regular Meeting, Agenda Item #10 - Accepted scope of services as shown in Task Order 2020-01 with HDR Engineering Inc. of the Carolinas in the amount of $1,285,257 for the design and bidding of the telemetry and remote terminal unit replacement project.
2) August 14, 2023, Regular Meeting, Agenda Item #23-104 - Approved Task Order 2020-05 with HDR Engineering Inc. of the Carolinas in the amount of $1,769,328 for construction administration services.
BACKGROUND:
The approved Capital Improvement Program includes funding for the assessment, design, and replacement of System Control and Data Acquisition (SCADA) infrastructure. Master planning for SCADA system replacement, radio communications analysis (telemetry), human machine interface (HMI) software acquisition activities, design and construction of required improvements for the SCADA system computer network (network architecture), and the design work for the replacement of the telemetry system, remote terminal units (RTUs) and programmable logic controllers (PLCs) have been completed. The telemetry and RTU replacement project was advertised, awarded, and is presently under construction.
To support the construction of the Telemetry and RTU Replacement project, construction administration services are required to ensure the project is constructed, tested, and integrated with existing systems in accordance with the project plans and specifications. The original scope of services for construction administration anticipated a 36-month project duration with a 75 percent utilization of a resident project representative (RPR). The project schedule has been extended by approximately 6 months and, due to greater than anticipated oversight needs, not only are additional hours for RPR services necessary but the utilization rate for RPR services must be increased to 100 percent for the remainder of the construction contract.
The additional scope of services detailed in the attached Amendment 01 to task order 2020-05 has been reviewed by UCW Engineering staff and is appropriate for the project. Services are to be provided on a not to exceed basis in the amount of $770,070 bringing the total contract amount to $2,539,398.
FINANCIAL IMPACT:
Funding is available within the adopted Capital Improvement Program to support the additional construction administration services described in Amendment 01 to Task Order 2020-05 in the amount of $770,070.
