Ill. Admin. Code tit. 44 § 2000.4060
The CPO will provide space standards that support efficient and cost-effective use of facilities, support flexibility, and provide employees with productive work environments. These space standards dictate the allotment of individual, collaborative, and support space. The planning of office space, size, and layout must be consistent with the standards listed in Appendix A. The Secretary of State's implementation of the space standards must be done in cooperation with the CPO and shall support the needs of the SOS. The CPO space standards are implemented to reduce costs, optimize the State facilities portfolio, and minimize construction costs, while providing employees with better workspaces in which they can collaborate, focus, and serve the citizens of the State of Illinois.
