PART 1 - GENERAL

1.1

DESCRIPTION

A.

The Drawings are diagrammatic, unless detailed dimensioned Drawings are
included, and show approximate locations of distribution equipment, fixtures,
control panels and wiring devices. Equipment layouts shall be submitted prior to
work in these areas with sufficient time for a detailed review. All equipment and
locations shall be closely reviewed and coordinated. Coordinate all work and
equipment locations with the Engineer prior to performing final installations.
While the general run of electrical feeders, branch circuits and conduits are indicated
on the Drawings, it is not intended that exact routing be determined there
from. Conductors can be combined in conduits for ease of construction as permitted
by these specifications and the latest edition of the N.E.C.

Circuit designations can be found on the contract drawings in the combination of
any of the following formats:

Single Line Diagrams Wiring Diagrams

Electrical Schematics Panelboard Schedules
Control and Instrumentation Diagrams Conduit and Wire Schedule
"Home Runs"

The Contractor shall be responsible for reviewing all drawings and may modify
these designations subject to field conditions and review of the Engineer.
Measurements shall be made and coordinated with all approved equipment at the
site and in the buildings during construction and all systems installed as the work
progresses in such a manner that the equipment, piping, vents, ducts, conduit, etc.,
will fit in the space provided, maintain head room and if in unfinished areas, be as
neatly installed, as obscure and "out-of-the- way" as physically possible.

Prior to submission for review any item of equipment, determine whether or not it
will fit in the space provided and that no design changes in conduits, wiring or
controls will be required. Any changes in the size, location or interconnections of
the material or equipment supplied, which may be necessary in order to meet field
conditions or in order to avoid conflicts between trades, shall be brought to the
immediate attention of the Engineer and no exceptions must be taken before such
alterations are made.

All equipment and accessories and its interconnecting piping, ductwork, conduits,
etc., shall be installed in such a manner that ample maintenance passage and Code-
required space/access will be provided.

Where more than one trade is involved in an area, space or chase, all shall cooperate
and install their own work to utilize the space equally between them in proportion
to their individual requirements. In general ductwork shall be given preference
(except where grading of piping becomes a problem) followed by piping then

electrical wiring. If, after installation of any equipment, piping, ducts, conduit, etc.,
it is determined that ample maintenance and passage space has not been provided,
the work shall be rearranged and/or furnished with other equipment as required to
provide this space at no additional cost to the Engineer. The Contractor shall review
the drawings for all other trades to determine any potential interferences and identify
and coordinate with those with other trades.

When there is a conflict or coordination issue, or if additional information is
necessary for the contractor to proceed with the intended work, a Request for
Information (RFI) form shall be submitted through the General Contractor to the
Engineer. The specific issue shall be described in the RFI and shall be sent to the
Engineer for review and a response shall be provided in an appropriate time period.
RFI form shall be available via the General Contractor through the Engineer as
required for this contract. This process shall be used as part of the work of this
contract.

QUALITY ASSURANCE

In General, the workmanship of the electrical installation shall be as described in the
N.E.C.A. Electrical Design Guidelines. All methods of construction, details of
workmanship, etc. that are not specifically described therein or indicated in the
Contract Documents, shall be subject to the control and approval of the Engineer.
Equipment and materials shall be of the quality and manufacture indicated in their
respective sections of the Specifications.

Work determined by the Engineer to be unsatisfactory according to industry
standards shall be redone at the Contractor's expense, with no additional
compensation.

All efforts shall be made in the location and installations of all raceways and
equipment for a neat, logical, and safe installation as it pertains to personnel and
operations.

An electrical conduit and associated electrical devices, etc., shall be installed
concealed wherever possible in order to provide for a clean and limited amount of
exposed conduit runs. Coordinate all work with the Engineer prior to performing
this work.
