11. Local authorities having jurisdiction over the work
Where the requirements set forth in these specifications or on the drawings are greater or more rigidthan the mandatory requirements referenced above, the applicable specifications or drawings shall
govern.
In the case of conflict between any mandatory requirements and specifications or drawings, the
mandatory requirements shall be followed in each case, but only after submitting such proposed
changes to the Owner for approval.
Nothing contained in these specifications or shown on the drawings will be so construed to conflict
with any national, state, municipal, or local laws or regulations governing the installation of work
specified herein, and all such acts, ordinances, and regulations, including the National Electrical
Code, are hereby incorporated and made a part of these specifications. All such requirements willbe satisfied by the Contractor at no additional expense to the Owner.
The drawings and specifications are complimentary to each other; what is called for by one shall be
as binding as if called for by both. If a conflict between drawings and specifications is discovered,
this shall be referred to the Owner as soon as possible for resolution. Should a conflict existbetween the drawings, specifications, and/or mandatory requirements (i.e., codes, ordinances, etc.),
it will be assumed that the more expensive method has been estimated, unless such alternate has
been agreed to prior to submission of bids.
18.1.5 Contractor Submittals
Shop Drawings: It is incumbent upon the Contractor to coordinate the work specified in these
Sections so that a complete instrumentation, computer, and control system for the facility will be
provided and will be supported by accurate shop and record drawings including an electronicversion in AutoCad, Landdesk Version 2005. Interface between existing instruments, existing
control panels, motor control centers, starters, control valves, flowmeters, chemical feeders, and
other equipment related to the instrumentation, control, and SCADA system shall be included in theshop drawing submittal.
In these Contract Documents all systems, meters, instruments, and other elements are representedschematically and are designated by numbers, as derived from criteria in Instrument Society of
America Standard ANSI/ISA S5.1. The nomenclature and numbers designated herein and on the
drawings shall be employed exclusively throughout shop drawings, data sheets, and similarmaterials. Any other symbols, designations, and nomenclature unique to the manufacturer's
standard methods shall not replace those prescribed above, used herein, and on the drawings.
Should an error be found in a shop drawing during installation or start-up of equipment, thecorrection, including any field changes found necessary, shall be noted on the drawing and
submitted finally "as-built" prior to acceptance of the project.

Conformance to the above wiring installation requirements shall be reflected by details shown on
the shop drawings for the Owners review.
Wire marking: Each signal, control, alarm, and indicating conductor connected to a given electricalpoint shall be designated by a single unique number which shall be shown on all shop drawings.
These numbers shall be marked on all conductors at every terminal using white numbered wire
markers which shall be plastic-coated cloth covered with clear heat shrink tubing or permanentlymarked heat-shrink plastic and must be durable, smudge and fade resistant.
18.3.3 RTU I/O Configuration
Listed References: A list of the I/O requirements (including used, future signals, and implemented
spares) for each RTU is provided through the database list of the existing Central Computer System.
Additional Requirements: Any power supplies, signal isolators, converters, interposing relays, etc.
that are necessary to make existing signals and equipment compatible with the I/O cards shall be
furnished and installed as a part of this Contract.
The input/output signals to be connected to the new RTUs shall be only the existing input/output,
plus any new instruments furnished under this contract, unless otherwise noted.
18.3.4 Calibration, Testing, and Start-up
Calibration: All instruments and systems furnished by the Contractor shall be calibrated after
installation, in conformance with the component manufacturer's instructions. This shall provide thatthose components having adjustable features are set carefully for the specific conditions and
applications of this installation and that the components and/or systems are within the specified
limits of accuracy. Defective elements which cannot achieve proper calibration or accuracy, eitherindividually or within a system, shall be replaced. This calibration work shall be accomplished by
the technical field representatives of the System Supplier whom the Contractor shall require tocertify in writing that for each loop of system, all calibrations have been made and that allinstruments are ready to operate.
Proof of Conformance: The burden of proof of conformance to specified accuracy and performance
is on the Contractor using its designated System Supplier. The Contractor shall supply necessary
test equipment and technical personnel if called upon to prove accuracy and/or performance, at noseparate additional cost to the Owner, wherever reasonable doubt or evidence of malfunction or
poor performance may appear.
Testing: All systems shall be exercised through functional and operational tests in the presence of
the Owner in order to demonstrate achievement of the specified performance. Operational tests
depend upon completion of work specified elsewhere in these Contract Documents. The schedulingof tests shall be coordinated by the Contractor among all parties involved so that the tests may
proceed without delays or disruption by uncompleted work.
Start-up: When all equipment and systems have been assessed by the Contractor to have beensuccessfully carried through complete operational tests with not less than a minimum of simulation
and the Owner concurs in this assessment, system start-up by the Owners operating personnel can
follow.
