How should future expansion space be protected in the layout?

In data center design, future expansion planning requires reserving space with clear, documented boundaries, allocating utility provisions (such as electrical and mechanical capacity), and imposing strict layout controls to prevent encroaching or incompatible activities from compromising future growth.

B: Routing permanent or immovable structural and utility obstacles through expansion space severely restricts or prevents future layout scalability.

C: Using reserved expansion space for permanent storage leads to space contamination and operational friction during future buildouts.

D: Excluding expansion space from facility drawings causes accidental encroachment, misallocation of space, and poor utility capacity planning.
