PSA24-2318UTIL Amend No. 3
Exhibit "A"
ENTERPRISE
AUTOMATION
This letter represents Enterprise Automation's (EA) formal request to amend or alter the scope, schedule, fee, or other pertinent project documents. A description of the project modifications is contained hereafter.
Justification for Contract Amendment
This amendment captures multiple unique new scope items, described in the sections below.
New Sites
Carlsbad Municipal Water District (the District) has recently finalized the construction of 6 new remote sites, listed below:
1. Villas Lift Station
2. Chinquapin Lift Station
3. El Fuerte and Rancho Pancho Motorized Valve Vault (Pressure Reducing Station)
4. Melrose Pressure Reducing Station
5. El Fuerte/Corintia Pressure Reducing Station
6. Lower El Fuerte Pressure Reducing Station
With the completion of construction of these sites, the District has asked that EA implement PLC & SCADA programming at these facilities using the templates developed as part of the District's SCADA Replacement project.
However, these sites are not in complete alignment with the template PLC & HMI programs developed as part of the SCADA Replacement project, and as a result, the templates need to be slightly modified to be flexible for the 1/0 and control present at the facilities. El Fuerte and the Rancho Pancho Motorized Valve Vault do not conform to any of the existing template PLC & HMI programs, so these sites require a new custom PLC program & HMI screen, similar to the custom screens of CWRF Pump Station and D Site.
The full scope of services captured in this amendment include updating the specifications developed as part of the SCADA Replacement project, modifying the existing Lift Stations & Pressure Reducing Stations template, developing a new El Fuerte and Rancho Pancho program, instancing the PLC program for each site from the template programs, including the new sites in the Ignition SCADA system, testing of the PLC & SCADA programs, and the execution of on-site commissioning tasks to start up the new sites.

Calavera Potable Pump Station (PS) Modifications
PSA24-2318UTIL Amend No. 3
Exhibit "A" (Cont.)
ENTERPRISE
AUTOMATION
The District has recently proposed significant mechanical & electrical modifications to the existing Calavera Potable Pump Station facility. EA needs to design both SCADA and PLC programs for this facility to ensure all future modifications are considered and included.
The Calavera Potable Pump Station is currently included with the Pump Station "template" PLC program and SCADA screen, which represents a total of 4 Pump Stations that are similar in 1/0 and functionality across the District. However, as a result of the proposed mechanical & electrical modifications, this template is no longer useful and should be broken down into 4 unique site programs & screens to improve future maintainability.
The full scope of services captured in this contract amendment includes updating the specifications developed as part of the SCADA Replacement project, developing a new functional specification for the Calavera Potable Pump Station, breaking out the existing Pump Station functional specification into unique specifications for each site included in the Pump Stations Template, developing the PLC, adding the updated configuration to the SCADA system, and testing of the PLC & SCADA programs.
Commissioning of this facility is already included in EA's current scope and as such was not included in this amendment.
Additional programming and Changes
During the recent Factory Acceptance Test (FAT) with the District, EA was asked to add multiple features and functionalities to the programs that were not initially scoped. Implementing some of the changes and programming updates require significant rework or hardwired 1/0 changes, additional programming time, and coordination with the future Citywide Electrical Control Panel Replacement contractor, testing and factory acceptance test.
Description of Contract Amendment
Initiation/Meetings
EA will require additional time for project setup, execution planning, kickoff meetings, and team check-in meetings. These tasks are crucial to the organized execution of this additional scope.
Specifications
EA has allocated budget for updating existing documentation related to the six new sites and the Calavera Pump Station Modifications project. Documentation that needs to be updated may include the master site list, PLC and SCADA tagging standards, 1/0 lists, network diagrams, and alarm specifications.
PLC/HMI Development
Additional time is required to develop and verify program instances for the six new sites in addition to updating the functional specifications to reflect process modifications at the Calavera Pump Station. The template pump station specifications will be divided into four separate documents to accommodate the differences between the Calavera Potable and Reclaim Pump Stations and the Bressie Potable and Reclaim Pump Stations.

PSA24-2318UTIL Amend No. 3
Exhibit "A" (Cont.)
ENTERPRISE
AUTOMATION
EA has budgeted to have additional workshop time to discuss and review control strategy with the District.
Due to the updates to the control strategies and design documents for Calavera Pump Station, additional budget is required to conduct programming/configuration tasks. Specifically, EA will need additional time for PLC programming and Ignition global setup configuration and screen development.
Testing
After completing the new PLC programs and screens for the new sites, as well as the updated PLC program and screens for the Calavera Pump Stations, EA will conduct internal integrated testing and Witnessed Factory Acceptance Testing (FAT). Any identified non-conformances will be addressed to ensure the system is fully prepared for implementation.
New Sites Commissioning
Once panels are ready to be commissioned, EA will execute panel-specific deployments and start up tasks alongside the current site commissioning plans for the main project. EA has included budget to complete on-site panel hardware checkouts, verify completed loop checks, and execute panel SAT procedures.
In addition to deployment tasks, EA has budgeted coordination time to join the construction meeting and provide support for the District or District's chosen Construction Manager, for this new scope. Here, EA will answer RFls and provide general support throughout the commissioning process as needed.
Closeout
Following the completion of commissioning of the new sites, EA will update automation design and construction standards to as built, reflecting any documentation changes made during commissioning. Panel drawing as-builts will be done by others.
