   4. D) Federal Space Standards

      Agencies requesting to use standards other than those established in this Appendix shall supply a copy of those standards to DCMS. In instances in which federal regulations require the use of federal space standards, the agency shall estimate its space requirements in accordance with the federal standards.

These space standards guide the design of interior spaces by establishing policies and requirements to provide State employees with functional work environments appropriate for their required tasks, maximize the efficient use of space, and enhance work areas for all employees and the public. Please note that, in some cases and based upon operations, unique functions and existing building conditions and dimensions that do not meet the space requirements of this Appendix may be greater and/or smaller than what is indicated. DCMS will evaluate and make final recommendations on a case by case basis.

These space standards will be reflected in the Space Request form, which is available from DCMS.

In the analysis of the basic units of activity, the following standards of space were developed to reflect the requirement of recurring, typical activities. The standards provide the occupant of each work station with space sufficient to conduct his/her business in an efficient manner. The amount of space allocated to each activity type includes allowances for various units of equipment and intrawork station circulation. Additional allowances are used for supporting space for each job position, as well as general circulation, conference rooms, reception area, special storage, and other unusual space requirements.
