Engineer may elect not to review partial, incomplete submissions, whereupon he will return the incomplete submission to the Contractor for a resubmission of a complete submittal.

126705 – Harrison Lake National Fish Hatchery 01300-3

1.04 TIMING OF SUBMITTALS

A. Except where otherwise specifically noted, allow 15 days, after receipt by Engineer, for Engineer to review and process submittals. Make submittals far enough in advance of scheduled dates of installation to provide time for reviews, for securing necessary acceptance, for possible revisions and resubmittals, and for placing orders and securing delivery.

B. Submissions may be returned unreviewed, rejected for several reasons, accepted conditioned upon submission of related items or for other reasons set forth in the Contract Documents.

C. Make submissions well in advance as the returning or rejecting of submissions or other similar circumstan-ces are possible and are deemed "avoidable delays" as defined in the General Conditions. Costs for these delays or those attributed to Contractor's tardiness in making submittals shall be borne by the Contractor.

1.05 DESTINATION OF SUBMITTALS

A. Unless otherwise specified, copies of every submission shall be sent to Engineer's home office as follows:

DuBois & King, Inc.

E. Prepare and submit, with the Construction Schedule, a separate schedule listing dates for submission of major shop drawings, submittals, and material samples.

2.04 SHOP DRAWINGS

A. Submit shop drawings for all fabricated work, for all manufactured items and for all other items specifically required by the Specifications.

B. Unless otherwise specified, submit six copies of each drawing, catalog cut, procedure, or other material.

If a resubmission is not required, Engineer will retain four copies and return the remaining copies to Contractor to be distributed.

126705 – Harrison Lake National Fish Hatchery 01300-8

C. Subcontractors must submit shop drawings directly to Contractor for checking. Thoroughly check subcontractors' shop drawings for measurements, sizes of members, details, materials, and conformance with the Contract Documents. Return submittals that are found to be inaccurate or in error. Do not submit to Engineer until corrections have been made.

D. Clearly show the relation of the various parts, and, where the Work depends upon field measurements, make measurements and include them on the shop drawings before submitting to Engineer.

E. Reference all submissions to clearly indicate the Specification Section, location, service and function of each particular item. Submissions for a single item, or group of related items, shall be complete.

When submitting manufacturers' catalogs, pamphlets or other data sheets, in lieu of prepared shop drawings, specifically identify in ink the items for which acceptance is being sought.

F. If the shop drawings contain any departures from the Contract requirements, specifically describe them in Contractor's letter of transmittal.
