USACE / NAVFAC / AFCESA / NASA UFGS-10 21 23.16 (April 2006) ------------------------------ Preparing Activity: NAVFAC Replacing without change UFGS-10191 (August 2004) UNIFIED FACILITIES GUIDE SPECIFICATIONS References are in agreement with UMRL dated January 2009 SECTION 10 21 23.16 CUBICLE TRACK AND HARDWARE 04/06 NOTE: This guide specification covers the requirements for the provision and installation of hospital cubicle tracks. 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). NOTE: Cubicle tracks may be mounted directly to ceiling or suspended from hangers. Hanger option should be chosen when ceiling heights are over 2700 mm 9 feet to reduce curtain length. Use I-beam section where accumulation of dirt on track (which would impede carrier movement) would be a problem. On the drawings, show: 1. Ceiling height 2. Anchorage system 3. Anchorage spacing and locations 4. If both heavy and light duty tracks are used, indicate locations of each. PART 1 GENERAL 1.1 REFERENCES NOTE: This paragraph is used to list the publications cited in the text of the guide specification.

Submittals should be kept to the minimum required for adequate quality control. A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be reviewed through the Contractor’s Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project. For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the "G" designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO" for District Office (Engineering Division or other organization in the District Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project Office. Codes following the "G" typically are not used for Navy, Air Force, and NASA projects. Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects. Government approval is required for submittals with a "G" designation; submittals not having a "G" designation are [for Contractor Quality Control approval.][for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government.] The following shall be submitted in accordance with Section 01 33 00 SUBMITTAL PROCEDURES: _{SD-02 Shop Drawings Cubicle track layout SD-08 Manufacturer's Instructions} Cubicle track _{installation SD-10 Operation and Maintenance Data Cubicle track system}, Data Package 1; [; _G][; _{G, [_____]}] Submit in accordance with Section 01 78 23 OPERATION AND MAINTENANCE DATA. 1.3 DRAWING REQUIREMENTS Submit _{cubicle track layout} drawings. Include [ceiling, surface-mounted installation details], [suspended track installation details] [, and] [overlay drawing showing other trades installation within area]. 1.4 DELIVERY AND STORAGE Deliver cubicle tracks to site in unopened containers clearly labeled with manufacturer's name and contents. Store in safe, dry, and clean location. Do not open containers until contents are to be installed. 1.5 QUALITY CONTROL Allow smooth, rapid, and complete screening with no gaps at corners or ends of track. The track of a standard 2400 by 2400 mm 8 by 8 foot cubicle shall have no joints. Form corner bends in a single continuous piece on a 300 mm 12 inch radius to exactly 90 degrees. Other track lengths to 4800 mm 16 feet shall have no joints. PART 2 PRODUCTS 2.1 _{CUBICLE TRACK SYSTEM} NOTE: Heavy duty track can be mounted either on ceilings directly or from hangers. The hanger option should be chosen when ceiling heights are over 2700 mm 9 feet to reduce curtain length. Heavy-duty type, [ceiling surface mounted] [hanger mounted]. Bends shall be minimum 450 mm 18 inches radius. 2.1.1 Extruded Aluminum Tracks NOTE: Use I-beam section where accumulation of dirt on track (which would impede carrier movement) would be a problem. I-beam types of track generally use the one piece. ASTM B 221MASTM B 221 and ASTM B 456; alloy 6063-TS, channel shape minimum 32 mm wide by 29 mm deep, 1 1/4 inch wide by 1 1/8 inch deep, 1.25 mm 0.050 inch minimum wall thickness. Inside raceway to be smooth for interior carriers and must be able to receive a double coated wheel carrier with hook. Finish as designated for aluminum finishes in AA DAF-45. 2.2 CARRIER UNIT Silent type with double canted wheel carrier. Wheels shall have nylon on stainless steel [chrome plated brass] [chromium plated steel] hooks with swivel to support the curtain. Carriers shall be removable only through access aperture or through end-cap that provides room for insertion or removal of carrier. Provide 2.2 carriers for every 300 mm foot of track length, plus one additional carrier. Provide a safety loading unit at one end of the channel track consisting of a section of channel track equipped with a hinge and end latch to permit lowering for installation of or removal of curtains from hooks without the use of a step-ladder and without removing carriers from track. Rivet moveable end of safety loading unit to be riveted to the hinge. Latching end of safety loading unit with a double locking fail-proof locking device for safety. Safety loading unit to be 1200 mm four feet in length of an 2400 mm 8 foot ceiling installation so latch end lowers to 1200 mm four feet from floor, for installation or removal of curtain without the use of a step-ladder. Increase length of safety loading unit to be increased according to ceiling height. Provide a key wand for every 20 units. 2.3 END STOP AND PULL-OUT Fabricate from aluminum or nylon with an anodized finish matching the track finish. 2.4 FASTENERS Stainless steel. 2.5 FINISH Satin, clear anodized. PART 3 EXECUTION 3.1 _INSTALLATION Verify dimensions prior to installation. Install cubicle track after painting and finishing operations are complete. Provide labor and all materials indicated, specified or necessary for a complete finished installation. Install track plumb, level and true, and securely anchored to the ceiling to form a neat, rigid installation. Remove damaged or defective components and replace with new components. 3.1.1 Installation Details NOTE: The types of ceilings to which the cubicle tracks or hangers will be fastened will differ. Therefore, in addition to showing the location of cubicle tracks on the drawings, the type of fastener or fasteners permitted for securing the tracks or hangers to the particular ceiling type for this project must be shown. NOTE: Generally, use hangers when room heights are 2700 mm 9 feet or more. Where hangers are used, indicate them on the drawings. Locate them: 1. At offsets or bends of 45 degrees or more. 2. At rises in track. 3. At 900 mm 3 feet on center, maximum, on straight cubicle tracks over 2400 mm 8 feet long. 4. At termination of track if not at wall or other attachable vertical surface. Install heavy-duty cubicle tracks [ceiling surface mounted] [suspended from hangers]. Install cubicle tracks where indicated. Install carrier units at 150 mm 6 inches on center maximum. Install end cap at each end of the track and pull-out at the end where curtains are stacked to permit insertion and removal of carrier units. Securely fasten end stops to prevent their being forced out by striking weight of carrier units.
