1-2.1.5 Integration of construction professionals into the facility design process.
1-2.1.6 Can provide the Government with multiple design solutions to consider in response to the
described need.
1-2.2 Definition. Design-build contracting results in a construction contract combining both the design
and construction of a facility into a single contract. By comparison, in traditional design-bid-build
contracting, design and construction are sequential and contracted for separately. There are a variety of
design-build contracting methods; a two-phase selection procedure under FAR 36.3 (reference 1-2) is
one of the types and is the methodology recommended for UEPH Complexes.
1-2.3 General Procedures. In general, the design-build process uses an RFP to solicit for design and
construction of a project by a single contractual entity. This entity may be a design-build firm, a joint
venture between an architect-engineer (A-E) and a construction firm, a construction management firm
joint venture with an A-E and a construction firm, a construction contractor prime with an A-E firm
subcontractor, an A-E firm prime with a construction subcontractor, a construction management firm at
risk, etc. A design-build RFP states the project minimum functional requirements, necessary design and
engineering criteria, technical performance requirements, proposal submission requirements, and
proposal evaluation factors. Potential contractors develop their proposals for the Government to evaluate
competitively, with the contract award based on a combination of technical merit and price. Therefore, the
contract is not awarded on the basis of initial construction cost alone, but also considers technical quality,
offeror qualification and management expertise, proposed materials and systems life-cycle costs,
aesthetics, and any other factors important to a specific project as identified in the RFP. This process is
referred to as a "Best Value" procurement.
1-2.4 The Two-Phase Process (reference 1-2). This document will highlight the process for using the
two-phase design build methodology in procuring UEPH Complexes.
The Two-Phase Process, in
summary, proceeds according to the following steps; a solicitation is issued which includes the general
scope of work for the project, the project budget, the Phase One and Phase Two proposal submission
requirements, all evaluation criteria to be used, and identifies the maximum number of proposals which
will participate in the second phase of the solicitation. Offerors are requested to submit their narrative
technical approach, their relevant experience and technical competence, their capability to perform,
proposed key personnel, their past performance examples and some other general information. No cost
or pricing information is requested or received in the Phase One process. Following completion of the
Phase One proposal evaluations, the most highly qualified offerors (not more than five) will proceed to
Phase Two and receive detailed technical requirements from which they will prepare their technical and
cost proposal. Completion of the evaluation of Phase Two proposals will result in an award to the most
highly qualified contractor whose proposal (offer) represents the best value solution to the solicitation.
The two phase methodology is best utilized when several conditions of the solicitation are anticipated,
most significant of these conditions are as follows:
1-2.4.1 Three or more offers are anticipated
1-2.4.2 Substantial expense to prepare technical proposals is expected
1-2.4.3 The following criteria must also be considered:
1-2.4.3.1 The extent to which the project requirements can be adequately defined
1-2.4.3.2 The time constraints for project delivery are known
1-2.4.3.3 The capability and experience of potential contractors
1-2.4.3.4 The capability of the design agent to manage a two-phase selection process
1-2.4.3.5 Any other specific criteria issued by the head of the Contracting Activity
1-2.5 Best Value and the Tradeoff Process. The tradeoff process is used when it is in the best interest
of the Government to consider award to other than the lowest price offeror or the highest technically rated
offeror. Under this process, both the cost and the non-cost factors are compared and analyzed and
award is made to the proposal which provides the Government the best value based on the published
evaluation criteria. Inherent in this process is the necessity to make tradeoffs considering the non-cost
strengths and weaknesses, risks, and the cost (or price) offered in each proposal. The Source Selection
