All programmed functions o f the PLC/SCADA instrumentation and industrial electronic
shall be provided under the supervision of a single Control System Integrator, contracted
directly by Owner, who is regularly engaged in the design, configuration, and installation
of similar systems of equal or greater scope and complexity. The Control System
Integrator shall NOT be enjoined by the Contractor as a Subcontractor. Programming of
the PLC and the SCADÀ system will be performed by others, but the associated
hardware will be supplied by Contractor. Contractor shall be responsible for ensuring
operability o f alt equipment in the instrument and control system ineluding network
systems, field equipment, panels, work stations, server racks, control panels, and
instruments . Programmed functionality o f all equipment in the instrument and control
system shall be the responsibility o f the CSJ. The Contractor shall work with CS1,
equipment vendors, and any third party PLC/SCADA programmer to test, commission
and start up the automated and programmed functions o f the plant.
2.
ITEMIZED RESPONSIBILITIES: The Contractor shall be responsible for the following
equipment and services:
a.
Detailed Design o f Control Panels: The drawings depict the functional and
operational requirements o f the control system and are at times diagrammatic. The
Contractor shall provide detailed, scaled design o f all components on and in control
panels and determine specific physical, thermal, and electrical requirements.
b.
Detailed Design o f Control Circuitry: The drawings depict the functional and
operational requirements of the control system and are at rimes diagrammatic. The
Contractor shall be responsible for the final selection o f all control system
components, except for components specified as “no equal”, and all detailed circuit
design and component interconnection required to meet the general and functional
requirements indicated in or implied by the Drawings and Specifications. Where
components are specified as "no equal”, the Contractor shall provide all detailed
design, including specification o f miscellaneous or interfacing components
required to integrate the specified component into the Contractor's control system
design. It is the responsibility o f the Contractor to ensure that all devices selected,
and the proposed interconnection o f those devices, perform as intended to provide
a complete and operable system meeting the requirements of the anticipated
environment and area classifications. The Contractor shall define all requirements
for all interfacing components and shall supply all appurtenances, accessories, and
all such devices which may be required for proper functioning and interfacing of
components as pail o f the control system. An example o f such appurtenances
would be interposing relays or analog isolators. All such aforementioned
necessary ancillary components not specifically indicated in the Contract
Documents shall be considered incidental to the contract and shall be required just
as if they had been specifically indicated.
c.
INTERCONNECTING WIRING; The design o f all interconnecting wiring of
control equipment, including remote control panels, packaged equipment panels,
mechanical equipment with control components, ctc. Provide PLC I/O schematics
for each PLC slot and M otor Starter schematics for each starter unit in the MCCs
