    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. 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, U.S. Army Corps of Engineers (HQUSACE), Naval Facilities Engineering Command (NAVFAC), and Air Force Civil Engineer Support Agency (AFCESA) 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 (CCR). The form is also accessible from the Internet sites listed below. UFC are effective upon issuance and are distributed only in electronic media from the following sources: • Whole Building Design Guide web site http://dod.wbdg.org/. Hard copies of UFC printed from electronic media should be checked against the current electronic version prior to use to ensure that they are current.

    UNIFIED FACILITIES CRITERIA (UFC)

    NEW DOCUMENT SUMMARY SHEET Description of Change: The UFC 4-159-03, DESIGN: MOORING represents another step in the joint Services effort to bring uniformity to the planning, design and construction of piers and wharves. This UFC contains extensive modifications in the following areas:

    Heavy Weather Mooring Passing Ship Effects Ship Generated Waves Conversion from Mil-Hdbk to UFC and general updates and revisions

    Reasons for Change: The existing guidance was inadequate for the following reasons:

    Need to convert to UFC format Incorporation of changes described above Update to referenced documents

    Impact: The following direct benefits will result from the update of 4-159-03, DESIGN: MOORING:

    Although primarily a U.S. Navy document, a single, comprehensive, up to date criteria document exists to cover mooring design.

    Eliminates misinterpretation and ambiguities that could lead to design and construction conflicts.

    Facilitates updates and revisions and promotes agreement and uniformity of design and construction between the Services.
