Purchasing and Professional Services Guidelines
Methods of Procurement
Metropolitan’s procurement is conducted in accordance with the Metropolitan Administrative Code.  The methods of procurement consist of competitive bidding, competitive proposals, requests for qualifications, and direct purchases.
  • Competitive bidding is primarily used for procurements for goods and non-professional services.
  • Competitive proposals are used for professional and technical services where technical approach and other factors are considered in making an award. 
  • Requests for qualifications are used where the scope of work is broadly defined. This method is used for either making an award to the most qualified provider or for pre-qualifying potential respondents for a subsequent competitive solicitation.
  • Direct purchase is authorized where conditions are met that allow exemption from competitive procurement.
Where more than one method of procurement is available, a method will be selected to promote an open, public procurement that avoids favoritism and provides the most value to Metropolitan.

Cooperative and Piggyback Contracts

Piggyback purchases are purchases made under the terms and conditions of another public agency’s contract when that contract includes a provision that extends its pricing, terms, and conditions to other public agencies.

A. The Contracting Services Manager, with the approval of the Chief Operating Officer and the General Counsel, may enter into a cooperative purchasing agreement to acquire materials and services under the contracts of other public entities, and may participate in, sponsor, conduct, or administer a cooperative purchasing agreement for the procurement of materials and services with one or more public entities.

B. When a requisition or a consultant services request whose projected contract amount is $25,000 or more is submitted, Contracting Services may determine that there is another public agency contract that can be used to make the acquisition.  Consideration for use of another public agency’s contract includes:

  1. The cost of the goods or services provided on the contract.

  2. The quality and specifications of the goods and services provided on the contract.

  3. The terms and conditions of the public agency’s contract.

  4. The circumstances surrounding the acquisition such as the time and cost involved in processing a Metropolitan solicitation.

Before entering into a cooperative agreement under which another public entity undertakes procurement, the Contracting Services Manager verifies that the public entity has conducted procurement through competitive procedures and that use of the cooperative agreement under consideration is economically advantageous to Metropolitan.  General Counsel verifies that the competitive procedures substantially meet the requirements of Metropolitan for competitive bidding.
