The designated procurement units may adopt master contracting, a streamlined procurement method, to provide for the qualification of an offeror in one or more categories of services, supplies, or commodities. If a designated procurement unit adopts master contracting, the master contracting method shall include: the categories of services, supplies, or commodities in which an offeror may submit a proposal for qualification; a procedure for the consideration and approval of proposals for qualification of multiple offerors in each category of services, supplies, or commodities; the execution of a standard contract for a specified period of time between the State and an offeror approved as a master contractor; and a performance evaluation procedure to be used by a unit of the Executive Branch to evaluate the performance of a qualified offeror that has completed work on a task order. A unit of the Executive Branch that requires services, supplies, or commodities covered under a master contract may issue a solicitation for a task order to a master contractor consistent with the regulations adopted under § 13–114 of this subtitle. Except as provided in subsection (f) of this section, the solicitation for a task order shall include a statement of the: factors that will be used in evaluating a master contractor’s response; and relative importance of each factor. This subsection does not apply to a task order designated as a small business reserve in accordance with § 14–502 of this article. Except as provided in subsection (f) of this section, if the unit of the Executive Branch expects that the total cost of the services, supplies, or commodities will exceed $500,000, the unit shall issue a solicitation for a task order to all master contractors in the appropriate category established by the designated procurement unit. If the unit of the Executive Branch expects that the total cost of the services, supplies, or commodities will exceed $100,000 but will not exceed $500,000, the unit shall issue a solicitation for a task order to a minimum of six qualified master contractors on a rotating basis for master contracts designated by the Chief Procurement Officer or all master contractors, whichever is less, in the appropriate category established by the designated procurement unit. If the unit of the Executive Branch expects that the total cost of the services, supplies, or commodities will be $100,000 or less, the unit shall issue a solicitation for a task order to a minimum of three qualified master contractors on a rotating basis for master contracts designated by the Chief Procurement Officer or all master contractors, whichever is fewer, in the appropriate category established by the designated procurement unit. Except as provided in subsection (f) of this section, after a unit of the Executive Branch receives responses from master contractors to a solicitation for a task order, the unit shall evaluate the responses and may select a master contractor based on the response that is determined to be the most advantageous to the State considering the evaluation factors set forth in the task order. Except as provided in paragraph (3) of this subsection, oral presentations are required prior to selecting a master contractor when: the total value of the task order is expected to exceed $2,000,000 for architectural and engineering services; the total value of the task order is expected to exceed $10,000,000 for construction and construction related services; or for all other procurement, including information technology and professional services, when the total value of the task order is expected to exceed $5,000,000. If the procurement officer makes a written determination that oral presentations are unlikely to aid in the evaluation process, oral presentations will not be required. The requirements of subsections (c)(2), (d), and (e)(1) of this section do not apply to a master contract for construction if the master contract: is awarded through a competitive process in accordance with this subtitle; and states: how task orders will be awarded; and the maximum number of qualified contractors that will be awarded a master contract for construction.
