building code
Building Code
  • A building code is a set of rules that specify the minimum acceptable level of safety for buildings. The main purpose of building codes are to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures.
  • A building built to the building code is the least safe building you can legally build.

Accessibility
  • ADAAG
  • Authority to use ADAAG
    • Design Standards
    • Clarifications
  • Tolerances
  • Construction Details
accessiblity
Accessiblity
  • Authority
    • HECO Manual 7A.1
      • Americans with Disabilities Act Accessibility Guidelines (ADAAG), published July 23, 2004 and excluding the Architectural Barriers Act [ABA] Scoping Requirements.
      • Standards of VUSBC Chapter 11 and the IPC §405 do not apply to University facilities on Commonwealth property.
    • Facilities Design Guidelines GR.2.1
      • ADAAG is applicable to Commonwealth of Virginia new and renovated construction projects.
design standards for accessibility
Design Standards for Accessibility

HECO Manual 7A.2.1

  • Americans with Disabilities Act Accessibility Guidelines, July 23, 2004.
  • Available on-line
    • http://www.access-board.gov/ada-aba/index.htm
  • Clarifications for University Owned Buildings
clarifications
Clarifications
  • Accessible facilities must be provided at the completion of construction.
  • Adaptable facilities do not meet the requirements for accessibility unless demonstrated to the University Building Official to be readily implemented on demand.
  • All stairways shall be accessible to the disabled.
facilities design guidelines
Facilities Design Guidelines
  • Facilities shall be designed so that accessibility does not stand out or draw attention to it when other architectural alternatives are available.
    • Example, restroom lavatories shall be of uniform design with all lavatories meeting accessibility standards rather than just one unit meeting the standards.
    • This would not apply to toilet stalls, urinals or water closets.
facilities design guidelines cont
Facilities Design Guidelines Cont
  • Teaching and research laboratories shall have a minimum of five percent, but not less than one, work station for each type of facility (fume hood, bench, sink, etc.).
  • Compliance may be achieved using readily adjustable modular casework and equipment.
tolerances
Tolerances
  • ADAAG has some minimum and maximum dimensions for some of the elements. If a minimum and maximum is given, there is no tolerance for the element being outside of that range. (ADAAG Advisory 104.1.1)
  • If a minimum or maximum is given there is some tolerance, but the tolerance is not defined.
    • Element should be dimensioned to ensure the minimum or maximum is not exceeded. Don’t show the limit.
