The material included in this UFC has been streamlined to be more concise. This revision to 3-520-01 coordinates with all electrical-related UFCs and provides consistent guidance with the other electrical-related UFCs. Standardized guidance has been prepared to assist electrical engineers in the development of the plans, specifications, calculations, and Design/Build Request for Proposals (RFPs). However, the following benefits should be realized. Impact: There are negligible cost impacts associated with this UFC. Update the material to reflect new and revised industry standards. Develop more concise electrical design guidance with this revision. Reasons for Document: Provide technical requirements for interior electrical system design criteria. Sections in this UFC will refer to this internet link when appropriate. Explanatory material existing in the prior revision of UFC 3-520-01 has been removed from this revision and has been made available at. This type of material has been removed from UFC 3-520-01 so that duplication of criteria is eliminated. UFC 3-501-01 provides overall electrical engineering criteria, including electrical design analysis and documentation criteria. This UFC has also been coordinated with new UFC 3-501-01, Electrical Engineering.

The document has been extensively revised to update the criteria for interior electrical systems. Description: This UFC 3-520-01 provides design guidance for interior electrical systems. UNIFIED FACILITIES CRITERIA (UFC) REVISION SUMMARY SHEET Document: 3-520-01, Interior Electrical Systems Superseding: UFC 3-520-01, Interior Electrical Systems, dated June 10, 2002. _ MICHAEL McANDREW Director, Facility Investment and Management Office of the Deputy Under Secretary of Defense (Installations and Environment) _ DENNIS FIRMAN Director of the Air Force Center for Engineering and the Environment Department of the Air Force Chief Engineer Naval Facilities Engineering Command 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. UFC are effective upon issuance and are distributed only in electronic media from the following source: Whole Building Design Guide web site. The form is also accessible from the Internet sites listed below. Recommended changes with supporting rationale should be sent to the respective service proponent office by the following electronic form: Criteria Change Request (CCR). Technical content of UFC is the responsibility of the cognizant DoD working group. Defense agencies should contact the preparing service for document interpretation and improvements. 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. 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. 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 more stringent of the UFC, the SOFA, the HNFA, and the BIA, as applicable. UFC will be used for all DoD projects and work for other customers where appropriate.
