for completely finished and operational systems. Provide all minor incidental items such as
offsets, fittings, etc. Required as part of the work even though not specified or indicated.
B. Description of Systems: The work of Division 16 includes but is not limited to:
1. Branch Circuit Power Distribution
C. Related Requirements:
1. General Requirements: Division 1 - All Sections
2. Division 16: All Sections
3.
Mechanical and Electrical Coordination: Division 15
D. Work Under Other Divisions:
1. Work Under Division 15
E. Examination: Examine work preceding or interfacing with the work of Division 16 Sections and
report any known or observed defects that affect the work to the General Contractor. Do not
proceed with the work until the defects are corrected. No waiver of responsibility for defective
work will be allowed due to failure to report unfavorable conditions affecting the work.
F. Existing Utilities: Existing Utilities are indicated as accurately as possible on the Drawings.
Work on utilities encountered and not indicated on the Drawings will be directed by change order
after being brought to the attention of the Architect. Close openings and repair damage in an
acceptable manner to utilities encountered.

B. Installation Procedures: Confer and cooperate with other trades and coordinate the work in proper
relation with theirs. Coordinate ceiling cavity space carefully with other trades.
C. Coordination with Mechanical Work: Division 15
D. Cutting and Patching: Section 16050.
E. Drawings and Specifications: The Drawings and Specifications are complementary; what is called
for in either of these is binding as though called for by both. The Electrical Drawings indicate the
general design and arrangement of lines, equipment, systems, etc. Information shown is
diagrammatic in character and does not necessarily indicate every required offset, fitting, etc. Do
not scale Drawings for dimensions. Take dimensions, locations, levels, etc. from Architectural
Drawings and equipment to be furnished. No extra compensation will be allowed on account of
differences between actual dimensions and those indicated on the Drawings.
F. Discrepancies:
1. Examine Drawings and Specifications for other parts of the work, and if any discrepancies
occur between the plans for the work of this Division and the plans for the work of others,
report such discrepancies to the General Contractor and obtain written instructions for any
changes necessary.
2. Make changes, at no additional cost to the Owner, to the work of Division 16 made
necessary by the failure or neglect to report such discrepancies. However, it is not the intent
of the Specifications that the Contractor be responsible for the correct design of the
electrical system.
G. Order of Precedence: The precedence of electrical construction documents is as follows:
1. Addenda and modifications to the Drawings and Specifications take precedence over the
original Drawings and Specifications.
2. Should there be a conflict within the Specifications or with Drawings of the same scale, the
more stringent or higher quality requirement shall apply.
3. In the Drawings, the precedence shall be Drawings of larger scale over those of smaller
scale, figured dimensions over scaled dimensions and noted material over graphic
indications.
4. Should a conflict arise between the Drawings and the Specifications, the Specifications shall
have precedence.
5. Should there be a conflict in the dimensions or locations between Electrical Drawings and
Architectural Drawings, the Architectural Drawings shall have precedence.
1.03
SUBMITTALS
A. Submit samples, shop drawings and product data as required by various sections of Division 16 in
accordance with Section 01300. Make submittals to Architect. Do not make submittals directly
to Engineer. Include one additional copy above the requirements of Section 01330.
