Iron Mountain’s current RCH-3 page forecasts phased delivery during 2028–2029. This remains a future schedule, not a construction-start or operating-capacity confirmation. Iron Mountain RCH-3 Richmond Data Center is one of four named future buildings in Iron Mountain’s White Oak Technology Park expansion. The building design is 60 MW, while Q2 2026 SEC reporting keeps 216 MW of Richmond future phases in held-for-development rather than under-construction capacity. The profile records the 300 MVA campus substation plan and Virginia incentive performance context without claiming construction commencement or a building-specific benefit. Customer utilization, private contract terms and unreported project financing remain outside the verified public record.
