Data Center Construction stages methodology
While no two campuses are identical, Aterio's standardized model gives a consistent, reliable way to benchmark construction progress regardless of provider or design. For each facility, Aterio's dataset includes brief, descriptive notes to provide concise context on what is happening on the ground.
Aterio’s Percentages Framework for Data Center Developments:
5%: Site clearing initiated (vegetation or existing structures removed)
10%: Land grading and leveling in progress
15%: Foundation work underway (concrete footings, pads, etc.)
20%: Vertical construction begins (initial steel framing rising)
30%: Structural steel framing completed
40%: Roof installation begins
50%: Roof installation completed
60%: Roof fully installed; mechanical equipment being placed
70%: External building prep begins (equipment pads, trenching, facade work)
85%: Roof finalized; generator installation begins
90%: Cooling and generator equipment being installed on site
95%: Building structure and core equipment fully installed; final site work and testing underway
