FEMA/TDEM Project No. 4586-263 and Shop Drawings which have not been reviewed by the Engineer of record shall not be used in fabricating or installing any work.

G. List deviations and exceptions from the specified equipment in writing and submit Shop Drawings as required by this section. Shop drawings must be submitted if proposed equipment differs in physical size than specified equipment to indicate proposed equipment has been coordinated with other trades and space allocated for this equipment. Shop Drawings must be at a 1/4" per foot scale indicating proposed equipment layout and any other equipment/materials noted in that general area. Failure to do so will be cause for rejection of submittals. Contractor agrees that if deviations, discrepancies, or conflicts between Shop Drawing submittals and the Contract Documents are discovered either prior to or after Shop Drawing submittals are reviewed by the Engineer of record, the Contract Documents shall control and shall be followed, unless deviations have been specifically approved by the Engineer of record.

The review of Submittals or catalog data by the Engineer of record shall not relieve the Contractor from responsibility for deviations from plans and specifications unless they have, in writing, specifically called attention to such deviations at the time of submission and has obtained the permission of the Engineer of record thereon; nor shall it relieve them from responsibility for error of any kind in Shop Drawings. When the Contractor does call such deviations to the attention of the Engineer of record, they shall state in their letter whether or not such deviations involve any extra cost. If this is not mentioned, it will be assumed that no extra cost is involved for making the change.

I. Contractor agrees that Submittals and Shop Drawings reviewed by the Engineer of record are not change orders; that the purpose of Shop Drawing submittals by the Contractor is to demonstrate to the Engineer of record that the Contractor understands the design concept, that they demonstrate their understanding by indicating which equipment and material they intend to furnish and install and by detailing the fabrication and installation methods they intend to use.

J. Failure to submit scaled Shop Drawings will indicate that the Contractor has coordinated their efforts with other trades and finds no conflicts with the work presented in the Contract Documents.
