SCOPE OF WORK
May 3, 2024
PROJECT UNDERSTANDING AND BACKGROUND
The City of Chandler Pecos Surface Water Treatment Plant (PSWTP), located at 1475 East Pecos
Road, was put into service in 1989 and PSWTP produces drinking water for the City’s residental and
commercial customers. Additionally, the control of the City’s potable water distribution network is
also housed at PSWTP. In order to protect the health and safety of the water customers, City staff
relies heavily on automation to reliably communicate with water facilities. This automation is in the
form of the Supervisory Control and Data Acquisition (SCADA) system. SCADA controls and monitors
PSWTP equipment and 55 remote potable production facilities. The SCADA system also includes
remote monitoring capabilities for 21 remote wastewater sites. Beyond system control, SCADA also
captures numerous data points for system analysis and regulatory reporting. The City’s 2019 SCADA
Master Plan identified a project to replace the existing Foxboro system.
The PSWTP SCADA Upgrade project will modernize and improve the City’s existing system and will
include upgrades to legacy hardware and software. The project will replace the existing Foxboro I/A
Distributed Control System (DCS) with Modicon PLCs and Wonderware HMI. This effort will entail
hardware replacement, upgrades to operational technology (OT) (i.e. the systems that control and
monitor treatment plant functions), integration with remote facilities, and possible replacement of
other obsolete equipment, such as power supplies or radio components. The project will include
procurement and installation of new virtual machine servers, software packages, Win911
applications with cellular modem and domain servers, and creation of SCADA software screens. No
treatment process upgrades are contemplated. The project will use a Construction Manager at Risk
(CMAR) delivery approach and is expected to be completed on a fixed budget and schedule.
This document describes the scope of work for services to be provided by Jacobs Engineering Group
Inc. (CONSULTANT) for the City of Chandler (City and OWNER) for the Pecos SWTP SCADA Upgrade
Construction Management Project WA2103.451 for execution of the work covered in Amendment 1
for Programming. Tasks include:
•
Commissioning of the SCADA System (Programming remaining focused on the field
testing and programming/software cut-over after all hardware upgrades are installed by
the CMAR)
•
SCADA Training for City Operations Staff (To ensure the plant operators are trained on
the new SCADA system prior to cutover)
•
Plant Electronic O&M Manual (Replacement of defunct overall plant operations manual
using new cloud-based software)

In addition, commissioning tasks are included for coordination with information provided by
the CMAR on any field changes and performing the software cut-over for the system.
A. Task 4.1.1 – Configuration Management
i. Cutover Meetings bi-weekly for 78 weeks
B. Cutover and Startup Plan
C. Task 4.1.7 HMI and PLC Commissioning

Test (FAT), except using real field sensors and equipment. Plant
interlocking and communications with PLCs and HMI shall be tested on
loop-by-loop basis.
c. Test procedures provided by CONSULTANT based on Loop specifications.
ii. Performance Acceptance Tests (PAT):
a. Once a facility area has been started up, perform a witnessed PAT on
complete Process Control System and software to demonstrate that it is
operating as required by the Contract Documents and software loop
descriptions. Demonstrate each required function on a paragraph-by-
paragraph, loop-by-loop basis.
b. Loop-specific and non-loop-specific tests same as required for FAT except
that entire installed SCADA system will be tested using actual process
variables and all functions demonstrated.
c. Perform local and manual tests for each loop before proceeding to remote
and automatic modes.
d. Where possible, verify test results using visual confirmation of process
equipment and actual process variable. Unless otherwise directed,
exercise and observe devices supplied by others, as needed to verify
correct signals to and from such devices and to confirm overall system
functionality. Test verification by means of disconnecting wires or
measuring signal levels is acceptable only where direct operation of plant
equipment is not possible.
e. Make updated versions of documentation required for PAT available to
Owner at Site, both before and during tests.
