ADDENDUM TO EXHIBIT B
ENGINEERING SERVICES
GENERAL
The purpose of this supplemental contract is to develop SCADA HMI and PLC standards. These
standards will be used by both the Phase 2 and Phase 2A contractors resulting in a reduction of
each contractor’s scope and elimination of duplicate work. These standards will assist BCRUA in
both present and future SCADA system development, ensuring that programs and applications
maintain a consistent look, operation and functionality which will minimize troubleshooting and
maintenance. Included is the development of code blocks and objects that can be reused, reducing
development time on present and future projects. Additional items covered in this scope include
tagging guidelines, startup requirements and procedures for working on BCRUA SCADA systems.
Finally, a change management procedure will be documented for the Ignition HMI Software to
provide a method for BCRUA to manage their programs and documentation.
These standards are critical for consistent and reliable SCADA system development,
implementation and maintenance. Proper use will reduce maintenance and operations costs as
well as improve the overall functionality, reliability and maintainability of the system. As the
developers of these standards, Engineer will provide review and oversight of the SCADA HMI
graphics and PLC code for both the Phase 2 and Phase 2A projects to ensure standards compliance
and a consistent end result for BCRUA.
