Adjusted Low Bid – A form of best-value selection in which qualitative aspects of the selection criteria are scored on a 0 to 100 scale expressed as a decimal; bid price is then divided by qualitative score to yield an “adjusted bid” or “cost per quality point.” Award is made to the design-builder with the lowest “adjusted bid.”
Best Value – Also known as “greatest value,” a selection process in which proposals contain both price and qualitative components, and award is based upon a combination of price and qualitative considerations. “Qualitative” can be further delineated in terms of “technical design” and/or “management plan.”
Bid Proposal – A technical proposal and a separately sealed price proposal.
Change Order – A written document signed by the client and the design-builder authorizing a change in the work or an adjustment in the contract sum or the contract time.

Conceptual Schedule – Derived in a similar way to a conceptual estimate (see above), it is a determination of the true amount of time that will be required to complete a project, including allowances for contingencies, that is: how long you should realistically expect it to take .
Construction Management (CM) – A project delivery method in which the client retains a construction manager (often the design firm) to provide certain preconstruction expertise including cost estimating, value engineering, and scheduling and, during the construction phase of the project, the coordination of all construction activities. The construction manager serves as an advisor to the client and is paid a professional services fee.

Equivalent Design/Low Bid – A form of best-value selection in which qualitative proposals are followed by a critique rather than scoring. Price envelopes remain sealed. Each design-builder receives the critique of its proposal and responds with design changes and corresponding price amendment. Revised designs are evaluated for compliance and price envelopes, both base and amendment, are opened. Award is made on basis of lowest price because the proposal critique creates relative equivalency of designs.
Fast-Track or Fast-Tracking – The process of designing portions of a project while portions already designed are under construction. A series of controlled design-build sequences that collectively constitute a complete project.
Fast Track Construction – A method of construction management that involves a continuous design-construction operation when a prime or main contractor starts the construction work before the plans and specifications are complete.
