SECTION 01340
SHOP DRAWING PROCEDURES
PART 1 - GENERAL
A. DESCRIPTION
1. The submittal of Shop Drawings shall conform to requirements of Contract
Documents and procedures described in this Section. A separate transmittal
form shall be used for each specific item or class of material or equipment for
which a submittal is required. Transmittal of Shop Drawings on various items
using a single transmittal form shall be permitted only when the items taken
together constitute a manufacturer's "package" or are so functionally related that
expediency indicates review of the group or package as a whole. The item(s) to
be supplied shall be highlighted clearly.
2. The term "Shop Drawing" as used herein shall be understood to include detailed
design calculations, fabrication and installation drawings, lists, graphs, test data,
operating instructions, and other items which shall include, but not are
necessarily limited to:
a. Drawings and/or catalog information and cuts.
b. Specifications, parts list, suggested spare parts lists, and equipment
drawings.
c. Wiring diagrams of systems and equipment.
d. Complete lubrication, maintenance and operation instructions, including
initial startup instructions as described in Section 01731, Instruction of
Operations and Maintenance Personnel.
e. Applicable certifications.
f. Anchor bolt templates, mounting instructions and mounting design
calculations as required.
g. Required maintenance operations to allow all installed equipment to
remain idle for a period of time not to exceed 24 months.
h. Other technical, installation, and maintenance data as applicable.
i. Unloading and handling methods and storage requirements.
j. Note, highlight, and explain proposed changes to the Contract Docu-
ments.

CORROSION PROTECTION SYSTEM 01340
3. Submittal Schedule: The CONTRACTOR, within ten (10) days after the Notice of
Award Date, shall prepare and submit to the City a comprehensive Submittal
Schedule. The CONTRACTOR shall identify on his Submittal Schedule all of the
submittal items required by the Contract Documents governing his Work. The
CONTRACTOR shall indicate, for each submittal item on his Submittal Schedule
the following:
a. Description and Transmittal Number;
b. Reference to the applicable paragraph in the Contract Documents in
chronological order that requires the submittal;
c. The dates the CONTRACTOR proposes to furnish the submittals;
d. The dates the materials, equipment, etc. are needed at the job site; and
e. The date confirmation of compliance is needed by the CONTRACTOR (a
minimum of 30 days from the date the City receives the shop drawing
unless otherwise noted in the Contract Documents).
f. Whether the submittal is for a deviation or an "equal" item. Complete
submittals for all deviations or "equal" items shall be made to the City
within 7 calendar days after the Notice of Award. Identification by the
CONTRACTOR of deviations or "equal" items does not relieve the CON-
TRACTOR of his responsibility to furnish equipment and materials that
meet all the requirements of the Contract Documents.
4. In preparing his Submittal Schedule, the CONTRACTOR shall consider the
nature and complexity of each submittal item and shall allow ample time for
review, revision or correction. Submittals will normally be returned to the
CONTRACTOR within 30 calendar days following receipt of the submittal.
5. The City will review the CONTRACTOR'S Submittal Schedule to determine its
completeness and compatibility with the Progress Schedule. A Submittal
Schedule which is incompatible with the Progress Schedule or a review schedule
which places extraordinary manpower demands on the City will be sufficient
reason(s) to reject the Submittal Schedule. It shall be understood that certain
submittals will take longer than 30 days to review and that these particular
submittals will be identified during the submittal, by the PWD to allow for very
complex submittal reviews. The CONTRACTOR shall also identify submittals for
which he anticipates long review periods.
6. The CONTRACTOR'S Submittal Schedule shall be consistent with the Progress
Schedule.
7. City’s acceptance of the Submittal Schedule will be a precondition of the receipt
of the first progress payment.

form. Any Shop Drawing submittal not accompanied by such a form, or where all
applicable items on the form are not completed, will be returned for resubmittal.
Ultimate responsibility for the accuracy and completeness of the information
contained in the submittal shall remain with the CONTRACTOR. If data for more
than one Section of the Specifications is submitted, a separate transmittal letter
shall accompany the data submitted for each Section. A copy of all transmittal
letters shall be sent to the City.

marked, CONTRACTOR shall repeat the initial approval procedure utilizing
acceptable material and/or equipment.
15. Any related Work performed or equipment installed without a "No Objection" or
"No Objection; Make Corrections Noted" Shop Drawing will be at the sole
responsibility of the CONTRACTOR.

thereof has been obtained in the specified manner.
17. City will review and process submittals within 30 calendar days following
submittal receipt.
18. It is CONTRACTOR'S responsibility to review submittals made by his suppliers
and subcontractors before transmitting them to PWD to assure proper

In the event that CONTRACTOR requests a substitution for a previously approved item,
all of City’s costs in the reviewing of the substitution will be back charged to
CONTRACTOR, unless the need for such substitution is beyond the control of
CONTRACTOR.
20. The City reserves the right to withhold monies, up to the limit identified in the
Contract Documents, for Shop Drawing reviews beyond those described herein.
21. The City will implement, if requested by the CONTRACTOR, one (1) special

SAN JUAN HILLS GREENS 31 Shop Drawings and Procedures
CORROSION PROTECTION SYSTEM 01340
of the Work. Requirements of this Section will not be waived but could be
expedited.
22. Extension of contract time will not be granted because of CONTRACTOR’S
substitutions, or because of the CONTRACTOR’S failure to make timely and
correctly prepared and presented submittals with allowance for the checking and
review periods.
23. The acceptance of submittals shall not relieve the CONTRACTOR of
responsibility for any deviation from the requirements of the Contract Documents
or for any revision in resubmittals unless the CONTRACTOR has given notice in
writing of the deviation or revision at the time of submission or resubmission and
written approval has been given to the specific deviation or revision. Acceptance
