2 UFC 3-250-01 14 November, 2016 FOREWORD The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, Design , construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L) Memorandum dated 29 May 2002. UFC will be used for all DoD projects and work for other customers where appropriate. All construction outside of the United States is also governed by Status of Forces Agreements (SOFA), Host Nation Funded Construction Agreements (HNFA), and in some instances, Bilateral Infrastructure Agreements (BIA.) Therefore, the acquisition team must ensure compliance with the most stringent of the UFC, the SOFA, the HNFA, and the BIA, as applicable.

3 UFC are living documents and will be periodically reviewed, updated, and made available to users as part of the Services responsibility for providing technical criteria for military construction. Headquarters, Army Corps of Engineers (HQUSACE), Naval Facilities Engineering Command (NAVFAC), and Air Force Civil Engineer Center (AFCEC) are responsible for administration of the UFC system. Defense agencies should contact the preparing service for document interpretation and improvements. Technical content of UFC is the responsibility of the cognizant DoD working group. Recommended changes with supporting rationale should be sent to the respective service proponent office by the following electronic form: Criteria Change Request. The form is also accessible from the Internet sites listed below.

5 Description: This revision provides Pavement Design procedures and requirements for the Pavement Design of Roads and Parking Areas worldwide. It clarifies when State Pavement Design procedures may be used and when Pavement -Transportation Computer Assisted Structural Engineering (PCASE) is required. Reasons for Document: This UFC updates the guidance and requirements for specialized Pavement Design and underdrain Design in two existing criteria documents and efficiently consolidates them into a single UFC. Provides consistency in applying Pavement Design requirements for projects with standard vehicle types, particularly with regard to using State Pavement Design procedures. Impact: This unification effort will result in less cost to maintain DoD criteria and a more efficient Pavement Design in the following ways: By relying on State Pavement Design procedures for standard vehicle types that typically travel local Roads .

6 Reduction in the number of references used for military construction provides a clear and efficient guidance for the Design and construction of DoD pavements. Reduction in ambiguity and the need for interpretation reduces the potential for Design and construction conflicts. Unification Issues: None.
