the dimensions are of particular importance, or when so specified, the drawings shall be
certified by the manufacturer or fabricator as correct for this Contract.

All shop and working drawings shall be submitted to the Engineer by and/or through the
Contractor, who shall be responsible for obtaining shop and working drawings from his
subcontractors and returning reviewed drawings to them.

Only drawings which have been prepared, checked and corrected by the fabricator should
be submitted to the Contractor by his subcontractors and vendors. Prior to submitting
drawings to the Engineer, the Contractor shall check thoroughly all such drawings to
satisfy himself/herself that the subject matter thereof conforms to the Contract Documents
in all respects. Shop drawings shall be reviewed and marked with the date, checker's name
and indication of the Contractor's approval, and only then shall be submitted to the
Engineer. Shop drawings unsatisfactory to the Contractor shall be returned directly to their
source for correction, without submittal to the Engineer. Shop drawings submitted to the
Engineer without the Contractor's approval stamp and signature will be rejected. Any
deviation from the Contract Documents indicated on the shop drawings must be identified on
the drawings and in a separate submittal to the Engineer, as required under subsection 6.17
Shop Drawings and Samples; D. Submittal Procedures, Paragraph 3 of the General
Conditions.

The Contractor shall be responsible for the prompt submittal and re-submittal, as
necessary, of all shop and working drawings so that there will be no delay in the work due to
the absence of such drawings.

The Engineer will review the shop and working drawings as to their general
conformance with the design concept of the project and general compliance with the
information given in the Contract Documents. Corrections of comments made on the
drawings during the review do not relieve the Contractor from compliance with
requirements of the Contract Documents. The Contractor is responsible for: confirming and
correlating all quantities and dimensions; selecting fabrication processes and

01330-1

techniques of construction; coordinating his work with that of all other trades; and
performing his work in a safe and satisfactory manner. The review of the shop drawings is
general and shall not relieve the Contractor of the responsibility for details of design,
dimensions, code compliance, etc., necessary for interfacing with other components, proper
fitting and construction of the work required by the Contract and for achieving the specified
performance.

With few exceptions, shop drawings will be reviewed and returned to the Contractor within
15 days of submittal.

No material or equipment shall be purchased or fabricated especially for this Contract nor
shall the Contractor proceed with any portion of the work, the design and details of which are
dependent upon the design and details of equipment or other features for which review is
required, until the required shop and working drawings have been submitted and reviewed
by the Engineer as to their general conformance and compliance with the project and its
Contract Documents. All materials and work involved in the construction shall then be as
represented by said drawings.

Two copies of the shop and working drawings and/or catalog cuts will be returned to the
Contractor. The Contractor shall furnish additional copies of such drawings or catalog cuts
when he needs more than two copies or when so requested.
