1.2

1.3

DESCRIPTION

A.

Provide complete interior and exterior lighting systems, including fixtures,
standards, poles, hangers, supports, fittings, lamps, wiring, connections and controls,
as indicated in the Contract Documents.

The lighting layouts on the DRAWINGS are diagrammatic only. Lighting fixtures,
in general, have been specified for the particular type of ceiling in which they are to
be installed. Refer to Architectural "Reflected Ceiling Plans" for exact location of
recessed interior fixtures. Verify the ceiling construction details and provide fixtures
and mounting hardware suitable for the respective ceiling types.

Manufacturer's lighting fixture catalog numbers as indicated on the "Lighting
Fixture Schedule" indicate quality, type, efficiency and style but may not cover
special, required design details. Provide lighting fixtures having such special details
as noted in the "Lighting Fixture Schedule" and as required for proper installation.
Verify the availability of all fixtures proposed to be used in the execution of the
work prior to submitting same for the Engineer's review. The discontinuance of
production of any fixture after such review shall not relieve the Contractor from
furnishing an alternate fixture of equivalent quality and design without additional
cost to the Owner.

QUALITY ASSURANCE

A.

B.

All fixtures shall be new and shall bear the U_L. label for the service and location
intended.

Lighting fixtures shall be standard products of manufacturer regularly engaged in
the manufacture of the specific type lighting fixture specified as one of their
principal products and shall be the manufacturer's latest standard design that
complies with the specification requirements.

Lighting fixtures shall be as specified in the "Lighting Fixture Schedule" as shown
on the contract drawings. Although only one manufacturer has been named, the
phrase "or equal" may be applied to each fixture listed, unless otherwise noted. The
lighting design is intended to be of the highest electrical efficiency and fixtures have
been selected to provide the best illumination, at the lowest life cycle cost. The
Engineer reserves the right to disapprove any lamp or fixture type submitted which
is, in the Engineer's opinion, not equal in quality, appearance, efficiency or
performance to the fixture specified.

SUBMITTALS TO THE ENGINEER

A.

Shop Drawings are required for all items provided under this section. Submittals
shall be provided in accordance with Sections 01340, 16010 and as specified in this
section.
