USACE / NAVFAC / AFCESA / NASA UFGS-10 14 02 (February 2009) ----------------------------- Preparing Activity: USACE Superseding UFGS-10 14 02 (April 2006) UNIFIED FACILITIES GUIDE SPECIFICATIONS References are in agreement with UMRL dated January 2009 SECTION 10 14 02 INTERIOR SIGNAGE 02/09 NOTE: This guide specification covers the requirements for common types of signs, dimensional letters, and metal plaques used inside buildings. 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: This section covers some of the more common interior sign types. When other sign types are to be used, specifications will be modified accordingly. Buildings will be accessible in accordance with 36 CFR, Part 1191, Americans with Disabilities Act (ADA) Accessibility Guidelines for Buildings and Facilities except for Army buildings excluded by TI 800-01 Design Criteria. In combination with this specification, drawings and attachments will include location, dimensions, elevations, schedules, content, details and such other information as required to indicate the extent of the work. The same terminology and designations used in the specification will be used on the drawings, schedules and attachments. Product selections shall be based on quality, aesthetic values, appearance, and cost as related to project needs. Use of personal names in interior signage is discouraged. If personal names are required, changeable message strips will be used. Consider coordination of interior signage within this specification with signage required on individual workstations which is specified in Section 12 50 00 FURNITURE SYSTEMS. Interior stairwell signage will be provided in accordance with Life Safety Code NFPA 101, Chapter 5, and applicable occupancy chapters. Clearly define interstitial spaces or other doorways within stairwell that do not lead to a horizontal exitway with signage that states "Not an Exit". Permanent information on room identification signs includes the room number on all room identification signs, symbol and message on toilet rooms, message on janitor closets, mechanical/electrical and communications rooms, and message on stairs. Where appropriate for medical facilities, include the following requirements for signage: 1. Room numbering for spaces within the medical facility will be determined jointly by the using facility and the design team. User room number will be different than architectural room number (see MIL-HDBK 1191, 4.15.3). Room numbering will be consistent throughout the facility. For inpatient medical facilities, rooms with audiovisual nurse call shall have a unique user room number, since audiovisual nurse call is tied into a digital paging system. For outpatient clinics, rooms with tonevisual nurse call, do not need a unique user room number, since tonevisual nurse call is hardwired to a panel located at a nursing station. Room numbering should address the following issues: a. Wayfinding within clinics and other departments (user room #). b. Facility Maintenance (architectural room #). c. Audiovisual Nurse Call (inpatient) (unique user room #). d. Tonevisual Nurse Call (outpatient) (user room #). 2. The use of symbols/graphics on interior signage will be limited. International symbols and graphics will be used where needed. Recommended symbols include men/women symbol for toilet rooms and showers, men/women symbol with key for locker rooms, telephone symbol for public telephone areas, information (?), radiation symbol, biohazard symbol, and handicap symbol. 3. Arrow placement order on interior signage will comply with MIL-HDBK 1191, 4.15.2.2. Left pointing arrows at top of sign, followed by up pointing arrows, then right pointing arrows at bottom of sign. Example follows: < EMERGENCY ^ Orthopedic Clinic > Admissions 4. Signage schedule should be provided in electronic spreadsheet format. Schedule will include architectural room number, user room number, type of sign, message, symbol (if needed), color, and mounting location. 5. Building directories and accompanying orientation maps for the medical facility will be determined jointly by the using facility and the design team. Orientation maps, if required, will be included as part of the interior signage package, and should be of the same manufacturer. Include international symbols for information (?), parking areas (upper case P within circle), public toilet rooms, public telephones, and graphic north arrow on orientation maps. Orientation map is to be positioned so that building left is viewer's left. 6. Large, easy to read signs over reception counters, check-in counters, information desks, or departments will be provided. Signs should be either ceiling mounted or affixed to soffit directly above counters. 7. Room identification signs should be 20.32 cm x 20.32 cm (8 x 8 inch) or 22.86 cm x 22.22.86 cm (9 x 9 inch). Justification of room number and message will be flush left. 8. Fire evacuation signs will be provided in accordance with the local Fire Marshal, if required. 9. Overhead directional signs should not block fire exit signs. 10. Signage will clearly define all staff, public, or patient toilet rooms. 1.1 REFERENCES NOTE: This paragraph is used to list the publications cited in the text of the guide specification.
