3. REVIEW PROCEDURE
Submittals shall be submitted to the Construction Manager for review and returned within ten (10) working days after receipt. Review of submittals by the Design Consultant has as its primary objective the completion for the City of a project in full conformance with the Contract Plans and Specifications, unmarred by field corrections, and within the time provided. In addition to this primary objective, submittal review as a secondary objective will assist the Contractor in its procurement of equipment that will meet all requirements of the project Plans and Specifications, will fit the structures detailed on the Plans, will be completed with respect to piping, electrical, and control connections, will have the proper functional characteristics, and will become an integral part of a complete operating facility.
After review by the Design Consultant of each of the Contractor's submissions, the material will be returned to the Contractor with actions defined as follows:
A. NO EXCEPTIONS TAKEN (RESUBMITTAL NOT REQUIRED) -
Accepted subject to its compatibility with future submissions and additional partial submissions for portions of the work not covered in this submission.
Does not constitute approval or deletion of specified or required items not shown in the partial submission.
B. SUPPLY AS NOTED (RESUBMITTAL NOT REQUIRED) - Same as A, except that minor corrections as noted shall be made by the Contractor.
C. MAKE CORRECTIONS NOTED (RESUBMIT) - Rejected because of major inconsistencies or errors which shall be resolved or corrected by the Contractor prior to subsequent review by the Design Consultant.
D. REJECTED (RESUBMIT) - Submitted material does not conform to Plans and Specifications in major respect., i.e.: wrong size, model, capacity, or material.
Items A and B above (no resubmittal required) are considered "favorable review." Items C and D above (correction and resubmittal required) are considered "unfavorable review."
It shall be the Contractor's responsibility to copy and/or conform reviewed submittals in sufficient numbers for its files, subcontractors, and vendors.
