00140.70Cost Reduction Proposals - The Contractor may submit written proposals to the Engineer
that modify Plans, Specifi cations, or other Contract Documents for the sole purpose of reducing the total cost of construction. Unless otherwise agreed to in writing by the Agency, a proposal that is solely or primarily a proposal to reduce estimated quantities or delete Work, as determined by the Engineer, is not eligible for consideration as a cost reduction proposal and will instead be addressed under 00140.30, whether proposed or suggested by the Agency or the Contractor.
essential functions or characteristics of the Project , including , but not limited to, service life, 00140.70 34 economy of operation, ease of maintenance, designed appearance, or design and safety standards.
To conserve time and funds, the Contractor may first submit a written request for a feasibility review by the Engineer. The request should contain a description of the proposal together with a rough estimate of anticipated dollar and time savings. The Engineer will, within a reasonable time, advise the Contractor in writing whether or not the proposal would be considered by the Agency, should the Contractor elect to submit a detailed cost reduction proposal.
A detailed cost reduction proposal shall include without limitation the following information:
• A description of existing Contract requirements for performing the Work and the proposed change; • The Contract items of Work affected by the proposed change, including any quantity variation caused by the proposed change; • Pay I tems affected by the proposed change including any quantity variations; • A detailed cost estimate for performing the Work under the existing Contract and under the proposed change. Cost estimates shall be made according to Section 00197.

to Contract requirements until the Engineer issues a Change Order incorporating the cost reduction proposal. If the Engineer fails to issue a Change Order by the date specified in the proposal, the proposal shall be deemed rejected.
proposal. The Agency will not be liable to the Contractor for failure to accept or act upon any cost reduction proposal submitted. The Engineer will determine in its sole discretion whether to accept a cost reduction proposal as well as the estimated net savings in construction costs from the adoption of all or any part of the proposal. In determining the estimated net savings, the Engineer may disregard the Schedule of Items. The Engineer will establish prices that represent a fair measure of the value of Work to be performed or to be deleted as a result of the c ost reduction proposal.
proposal, the Agency reserves the right to require the Contractor to share in the Agency's costs of investigating the proposal. If the Agency exercises this right, the Contractor shall provide written acceptance of the condition to the Engineer. Such acceptance will authorize the Agency to deduct its share of investigation costs from payments due or that may become due to the Contractor under the Contract.
accepted in whole or in part, acceptance will be made by a Change Order that will include without limitation the following:
• Statement that the Change Order is made according to 00140.70; • Revised Contract Documents that reflect all modifications necessary to implement the approved cost reduction measures; • Any conditions to which the Agency's approval is subject; 00140.90 35 • Estimated net savings in construction costs attributable to the approved cost reduction measures; and • A payment provision according to which the Contractor will be paid 50% of the estimated net savings amount as full and adequate consideration for performance of the Work of the Change Order . The Contractor's cost of preparing the cost reduction proposal and the Agency's costs of investigating the proposal, including any portion paid by the Contractor, will be excluded from determination of the estimated net savings in construction costs. C osts of re -design, which are incurred after the Agency has accepted the proposal, will be included in the cost of the Work attributable to cost reduction measures.
If the Agency accepts the cost reduction proposal, the Change Order that authorizes the cos t reduction measures will also address any Contract Time adjustment.
