ACTION REQUESTED:
Accept the scope of services as shown in the attached Amendment 04 to Task Order 2020-02 with HDR Engineering, Inc. of the Carolinas in the amount of $139,850, and authorize the County Manager to negotiate and execute an agreement substantially consistent with this agenda item.
PRIOR BOARD ACTIONS:
1) May 3, 2021, Regular Meeting, Agenda Item # 9 - Approved Task Order 2020-02 with HDR Engineering, Inc. of the Carolinas in the amount of $396,582.
2) June 19, 2023, Regular Meeting, Agenda Item # 23-389 - Approved Amendment 02 to Task Order 2020-02 with HDR Engineering, Inc. of the Carolinas in the amount of $48,199.
BACKGROUND:
The Capital Improvement Program, as adopted by the Board of County Commissioners, 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), and human machine interface (HMI) software acquisition activities have been completed as part of the overall SCADA project effort. The master plan identified projects for implementation grouped into three main categories (1) network architecture, (2) telemetry, and (3) replacement of remote terminal units (RTU’s) and programmable logic controllers (PLC’s). The design and construction of required improvements for the SCADA system computer network (network architecture) has been completed. The design for the telemetry system and RTU and PLC replacements has been completed and the project is presently under construction. Supporting these projects is the implementation and deployment of the new HMI software.
The deployment and implementation of the selected HMI software, VTScada, is largely complete including the development of the object library, graphic interface, and establishing connectivity to the existing Data Flow Systems database. Amendments 01 through 03 to the scope of services with HDR Engineering of the Carolinas have been executed increasing the total contract amount by $123,006 from $396,582 to $519,588 to cover costs related to system training, updates and additions to the object library, and support services for the purchase, installation, and configuration of network equipment required to support VTSCADA at the Crooked Creek WRF.
Amendment 04 to Task Order 2020-02 includes costs for additional services required for the implementation and deployment of the HMI software for the Crooked Creek WRF; support services related to network security domain migration, VOIP alarm setup and configuration, data routing, and remote access coordination; and resolution of communication protocols at existing facilities. The additional services are required due to the complexities of implementing the VTSCADA HMI software with the existing Data Flow Systems hardware and database configurations.
The scope of services for VTScada deployment identified in the attached Task Order 2020-02 Amendment 04 has been reviewed by UCW Engineering staff and is appropriate for the project. Services are to be provided on a lump sum basis in the amount of $139,850 and increase the total contract amount from $519,588 to $659,438.
FINANCIAL IMPACT:
Funding is available within the adopted Capital Improvement Program to support the VTScada deployment professional services contract as described in Task Order 2020-02 amendment 04 in the amount of $139,850.
