"Provided Under Other Sections". "Furnish" means "to purchase and deliver to the
project site complete with every necessary appurtenance and support," and "Install"
means "to unload at the delivery point at the site and perform every operation
necessary to establish secure mounting and correct operation at the proper location

1.5 CONTRACT DOCUMENTS
A. Listing of Drawings does not limit responsibility of determining full extent of work
required by Contract Documents. Refer to Architectural, HVAC, Plumbing, Fire
Protection, Electrical, Structural, and other Drawings, and other Sections that
indicate types of construction in which work shall be installed and work of other
trades with which work of this Section must be coordinated.
B. Except where modified by a specific notation to the contrary, it shall be understood
that the indication and/or description of any item, in the drawings or specifications or
both, carries with it the instruction to furnish and install the item, regardless of
whether or not this instruction is explicitly stated as part of the indication or
description.
C. Items referred to in singular number in Contract Documents shall be provided in
quantities necessary to complete work.
D. Drawings are diagrammatic. They are not intended to be absolutely precise; they
are not intended to specify or to show every offset, fitting, and component. The
purpose of the drawings is to indicate a systems concept, the main components of
the systems, and the approximate geometrical relationships. Based on the systems
concept, the main components, and the approximate geometrical relationships, the
contractor shall provide all other components and materials necessary to make the
systems fully complete and operational.
E. Information and components shown on riser diagrams but not shown on plans, and
vice versa, shall apply or be provided as if expressly required on both.
F. Data that may be furnished electronically by the Designer is diagrammatic. Such
electronically furnished information is subject to the same limitation of precision as
heretofore described. If furnished, such data is for convenience and generalized
reference, and shall not substitute for Designer's sealed or stamped construction
documents.
1.6 DISCREPANCIES IN DOCUMENTS
A. Where Drawings or Specifications conflict or are unclear, advise Designer in writing
before Award of Contract. Otherwise, Designer's interpretation of Contract
Documents shall be final, and no additional compensation shall be permitted due to
discrepancies or unclarities thus resolved.
B. Where Drawings or Specifications do not coincide with manufacturers'
recommendations, or with applicable codes and standards, alert Designer in writing
before installation. Otherwise, make changes in installed work as Designer requires
within Contract Price.
C. If the required material, installation, or work can be interpreted differently from
drawing to drawing, or between drawings and specs, this contractor shall provide
that material, installation, or work which is of the higher standard.
D. It is the intent of these contract documents to have the contractor provide systems
and components that are fully complete and operational and fully suitable for the
intended use. There may be situations in the documents were insufficient
information exists to precisely describe a certain component or subsystem, or the
routing of a component. In cases such as this, where the contractor has failed to
notify the Designer of the situation in accordance with the paragraph above, the
contractor shall provide the specific component or subsystem with all parts
necessary for the intended use, fully complete and operational, and installed in
workmanlike manner either concealed or exposed per the design intent.
1. In cases covered by the paragraph above, where the contractor believes he
needs engineering guidance, he shall submit a sketch identifying his proposed
solution and the Designer shall review, note if necessary, and approve the
sketch.
1.7
MODIFICATIONS IN LAYOUT
A. Fire Protection Drawings are diagrammatic. They indicate general arrangements of
mechanical and electrical systems and other work. They do not show all offsets
required for coordination nor do they show the exact routings and locations needed

B. In all spaces, prior to installation of visible material and equipment, including access
panels, review Architectural Drawings for exact locations and where not definitely
indicated, request information from Designer.
C. Check Contract Drawings as well as Shop Drawings of all subcontractors to verify
and coordinate spaces in which work of this Section will be installed.

90% nominal voltage and 95% nominal frequency. All voltage sensing, frequency
sensing, and time delays shall be field adjustable. The transfer signal shall be
delayed for one second, delaying the transfer and engine start signals so as to
override momentary normal power outages.
K. The transfer switch shall have TRANSFER SWITCH NORMAL, TRANSFER
SWITCH EMERGENCY, and EMERGENCY ISOLATING SWITCH OFF pilot lights,
TEST, and SILENCE ALARM pushbuttons mounted on the flange of the enclosure.
The transfer switch shall be electrically operated and mechanically held and shall be
