USACE / NAVFAC / AFCESA / NASA UFGS-10 22 19 (April 2006) -------------------------- Preparing Activity: USACE Replacing without change UFGS-10615 (April 2005) UNIFIED FACILITIES GUIDE SPECIFICATIONS References are in agreement with UMRL dated January 2009 SECTION 10 22 19 DEMOUNTABLE MOVABLE PARTITIONS 04/06 NOTE: This guide specification covers the requirements for demountable and movable partitions. Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information. Remove information and requirements not required in respective project, whether or not brackets are present. Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet. Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR). PART 1 GENERAL NOTE: Demountable and movable partitions should be used in areas susceptible to future partition rearrangement. Compared to traditional drywall construction, installation of these partitions are faster and eliminate the cost and mess of cutting and fitting carpet and ceilings around fixed walls. They offer maximum flexibility and reusability to accommodate frequent and quick relocation of work without loss of materials, damage or modification to panels or to adjoining structures such as ceilings, fixed walls and floors. Movable partitions and some demountable partitions are non-progressive allowing the removal of individual panels from any location without disturbing adjoining units. The partitions are point accessible meaning instant access of panels allows for electrical, telephone and communication lines to be installed quickly and easily. Furniture support is an optional added feature that makes these partition systems similar to furniture systems panels. Partition layouts on the drawings must show partition dimensions, nominal sizes for doors, glazing panels, sound-resistance and fire-resistance when required, details and any other information pertinent to partition layouts. Partition layout should be based on module configuration to allow for maximum reusability. Designer should require materials, products, and innovative construction methods and techniques which are environmentally sensitive, take advantage of recycling and conserve natural resources. Many manufacturer's panels and components are 95% to 100% recyclable and reusable. 1.1 REFERENCES NOTE: This paragraph is used to list the publications cited in the text of the guide specification.
