A submittal marked "not reviewed" will be returned with an explanation of the reason it is not reviewed. Resubmit submittals returned for lack of review by Contractor or for being incomplete, with appropriate action, coordination, or change.

1.3.4.3 Disapproved or Rejected Submittals

Make corrections required by the COR. If the Contractor considers any correction or notation on the returned submittals to constitute a change to the contract drawings or specifications; notice as required under the Federal Acquisition Regulation (FAR) clause entitled CHANGES, is to be given to the Contracting Officer. Contractor is responsible for the dimensions and design of connection details and construction of work.

Failure to point out deviations may result in the Government requiring rejection and removal of such work at the Contractor's expense.

If changes are necessary to submittals, make such revisions and submission of the submittals in accordance with the procedures above. No item of work requiring a submittal change is to be accomplished until the changed submittals are approved.

1.3.4.4 Approved or Accepted Submittals

The COR's approval or acceptance of submittals is not to be construed as a complete check, and indicates only that design, general method of construction, materials, detailing and other information appear to meet the Solicitation and Accepted Proposal.

Approval or acceptance will not relieve the Contractor of the responsibility for any error which may exist, as the Contractor under the

SECTION 35 11 50 Page 9

Contractor Quality Control (CQC) requirements of this contract is responsible for design, dimensions, all design extensions, such as the design of adequate connections and details, etc., and the satisfactory construction of all work.

After submittals have been approved or accepted by the COR, no resubmittal for the purpose of substituting materials or equipment will be considered unless accompanied by an explanation of why a substitution is necessary.

1.4 VARIATIONS

Variations from contract requirements require both Designer of Record (DOR) and Government approval pursuant to contract Clause FAR 52.236-21 Alt 1, Specifications and Drawings for Construction, and will be considered where advantageous to the Government.

1.4.1 Considering Variations

Discussion with COR prior to submission, after consulting with the DOR, will help ensure functional and quality requirements are met and minimize rejections and re-submittals. When contemplating a variation which results in lower cost, consider submission of the variation as a Value Engineering Change Proposal (VECP).

Specifically point out variations from contract requirements in transmittal letters. Failure to point out deviations may result in the Government requiring rejection and removal of such work at no additional cost to the Government.

1.4.2 Proposing Variations

When proposing a variation, deliver written request to the COR, with documentation of the nature and features of the variation and why the variation is desirable and beneficial to Government, including the DOR's written analysis and approval. If lower cost is a benefit, also include an estimate of the cost savings. In addition to documentation required for variation, include the submittals required for the item. Clearly mark the proposed variation in all documentation.

Check the column "variation" of ENG Form 4025 for submittals which include proposed deviations requested by the Contractor. Set forth in writing the reason for any deviations and annotate such deviations on the submittal.

The Government reserves the right to rescind inadvertent approval of submittals containing unnoted deviations.

1.4.3 Warranting that Variations are Compatible

When delivering a variation for approval, the Contractor, including its Designer(s) of Record, warrants that this contract has been reviewed to establish that the variation, if incorporated, will be compatible with other elements of work.

1.4.4 Review Schedule Extension

In addition to normal submittal review period, a period of 10 working days will be allowed for consideration by the Government of submittals with variations.

SECTION 35 11 50 Page 10

1.5 PRODUCT SUBSTITUTIONS

A product substitution is a minor variation that changes a specific product, but does not change the overall design. Therefore, all information, requirements, stipulations, disclaimers, and guidance in VARIATIONS section applies to PRODUCT SUBSTITUTIONS as well.

Contractor is allowed to substitute called-out name-brand products for products of equal or greater specifications. Any additional cost will be covered by the Contractor. Contractor shall not purchase or install any substitutions prior to government approval. All proposed substitutions require government approval regardless of whether or not the submittal originally required government approval. All proposed substitutions shall be marked as a Variation as described in VARIATIONS. The Government reserves the right to rescind inadvertent approval of submittals found to not be properly marked as a Variation at no additional cost to the Government regardless of purchase or installation status.

1.5.1 Approved Substitutions

Substitutions are judged based on compliance to contract documents. It is the Contractor's responsibility to ensure all compatibility and performance prior to submission. The Government reserves the right to rescind inadvertent approval of submittals found to not be properly marked as a Variation at no additional cost to the Government regardless of purchase or installation status.

1.5.2 Disapproved or Rejected Substitutions

The Government is not responsible for any cost associated with the rejection of any substitutions.
