1/he P&Jus indicate theinen and not the precise nature of the iniunneuiin between the
individual instruments. Any exceptions taken to the implied interconnection shall be noted for
review by the Engineer.
C.
The instrumentation installation details on the Drawings indicate the designed installation for
the instruments specified. Where specific installation details are not specified or shown on the
Drawings, the American Petroleum Institute (API) Recommended Practice 550 shall be
followed as applicable.

D.
All work shall be executed in full accordance with codes and local rulings. Should any work be
performed contrary to said rulings, ordinances and regulations, the Contractor shall bear full
responsibility for such violations and assume all costs arising therefrom.
E.
Brackets and hangers required for mounting of equipment shall be provided. They shall be
installed in a workmanlike manner and not interfere with any other equipment.
F.
The shield on each process instrumentation cable shall be continuous from source to
destination and be grounded as directed by the manufacturer of the instrumentation equipment.
However, in no case shall more than one ground point be employed for each shield. Unless
otherwise necessary, all analog cables shall be grounded in the PLC I/O drop cabinets.
G.
The ISS, acting through the Contractor, shall coordinate the installation, the placing and
location of system components, their connections to the process equipment panels, cabinets
and devices, subject to the Engineer's approval. The ISS shall be responsible to insure that all
field wiring for power and signal circuits are correctly done in accordance with best industry
practice and provide for all necessary system grounding to insure a satisfactory functioning
installation. The Contractor hereunder shall schedule and coordinate his/her work under this
section with that of the electrical work specified under applicable Sections of Division 16 Electrical.
H.
Two complete sets of favorably reviewed shop drawings shall be kept at the job site during all
on-site construction. Both sets shall be identically marked up to reflect any modifications made
during field installation or start-up. All markings shall be verified and initialed by the Engineer or
his/her designated representative. Following completion of installation and the operational
readiness test, one set of the marked up drawings shall be provided to the Engineer, the other
retained by the supplier for incorporation of the mark-ups into final record documentation.
TESTING
A.
General
1.
The ISS shall provide testing of the equipment once installed in the field.
2.
Each test shall be in the cause and effect format The person conducting the test
shall initiate an input (cause) and upon the system's or subsystem's producing the
correct result (effect), the specific test requirement will have been satisfied.
3.
All tests shall be conducted in accordance with prior Engineer- approved procedures,
forms and checklist. Each specific test to be performed shall be described and a
space provided after it for sign off by the appropriate party after its satisfactory
completion.
4.
Copies of these sign off test procedures, forms and checklists will constitute the
required test documentation.
5.
Provide all special testing materials and equipment. Wherever possible, perform
tests using actual process variables, equipment, and data. Where it is not practical to
test with real process variables, equipment and data, provide suitable means of
simulation. Define these simulations techniques in the test procedures.
6.
The ISS shall coordinate all required testing with the Contractor, all affected
Subcontractors, the District, and the Engineer.
7.
The Engineer reserves the right to test or retest all specified functions whether or not
explicitly stated in the prior favorably reviewed Test Procedures until the functional

requirements of the overall system are met. No additional compensation shall be
provided for any required extended testing.
8.
The Engineer's decision shall be final regarding the acceptability and completeness
of all testing.
9.
The ISS shall furnish the services of field service engineers, all special calibration
and test equipment and labor to perform the field tests.
Any additional hardware or software that may be required to successfully verify

Field Testing
1.

Prior to start up the following tests are required:
Operational Readiness Test (ORT)
a.
0
b.
(1)
General: Prior to startup and the Functional Acceptance Test, the
entire system shall be certified (inspected, wired, calibrated, tested,
etc, and documented) that it is installed and ready for the ORT as
defined below.
(2)
Loop/Component Inspections and Tests: The entire system shall be
checked for proper installation, calibrated and adjusted on a
loop-by-loop and component-by-component basis to ensure that it
is in conformance with related submittals and these Specifications.
(3)
The Loop/Component Inspections and Tests shall be implemented
using Engineer-approved forms and checklists.
(4)
Each active Analog Subsystem element and each I/O module shall
have a Component Calibration Sheet.
(5)
The ISS shall maintain the Loop Status Reports and Components
Calibration sheets at the job site and make them available to the
Engineer/District at any time.
(6)
These inspections and tests do not require witnessing. However,
the Engineer will review and initial all Loop Status Sheets and
Component Calibration Sheets and spot-check their entries
periodically and upon completion of the Operational Readiness
Tests. Any deficiencies found shall be corrected.
(7)
Submit ORT results for review by the Engineer.
Functional Acceptance Test (FAT).
(1)
Prior to startup and the Functional Acceptance Test (FAT), the
entire installed instrument and control system shall be certified by
the ISS that it is ready for operation. All preliminary testing,
inspection, and calibration shall be complete as defined in the
Operational Readiness Tests.
(2)
Once the facility has been started up and is operating, a witnessed
FAT shall be performed on the complete system to demonstrate
that it is operating and in compliance with these Specifications.

(3)
Deficiency List items and resolutions noted during the test shall be
documented on the Deficiency List/Resolution form.
(4)
Submit FAT results for review by the Engineer.
Implementation, Startup, and Testing Plans are to be established for each milestone of
the project (i.e., shutdown No. 1, half plant outages Nos. 1 and 2, etc.).
