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.

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.
