4、rt: Pavement design means a project level activity where detailed engineering and economic considerations are given to alternative combinations of subbase, base, and surface materials which will provide adequate load carrying capac-ity. Factors which are considered in-clude: Materials, traffic, clim

(a) This regulation will establish a program to improve project quality, re-duce project costs, foster innovation, el
7、iminate unnecessary and costly de-sign elements, and ensure efficient in-vestments by requiring the application of value engineering (VE) to all Fed-eral-aid highway projects on the Na-tional Highway System (NHS) with an estimated cost of $25 million or more. (b) In accordance with the Federal- Stat
8、e relationship established under the Federal-aid highway program, State transportation departments (STDs) shall assure that a VE analysis has been performed on all applicable projects and that all resulting, ap-proved recommendations are incor-porated into the plans, specifications and estimate. 62
9、FR 6868, Feb. 14, 1997, as amended at 67 FR 75924, Dec. 10, 2002 627.3 Definitions. Project. A portion of a highway that a State proposes to construct, recon-struct, or improve as described in the preliminary design report or applicable environmental document. A project may consist of several contra
10、cts or phases over several years. Value engineering. The systematic ap-plication of recognized techniques by a multi-disciplined team to identify the function of a product or service, estab-lish a worth for that function, generate alternatives through the use of cre-ative thinking, and provide the n
11、eeded functions to accomplish the original purpose of the project, reliably, and at the lowest life-cycle cost without sac-rificing safety, necessary quality, and environmental attributes of the project. 627.5 General principles and proce-dures. (a) State VE programs. State transpor-tation departmen
12、ts must establish pro-grams to assure that VE studies are performed on all Federal-aid highway projects on the NHS with an estimated cost of $25 million or more.
