Completed in 2017, Keppel DC Singapore 4 rounded out the REIT's Tampines trio, rising five storeys within walking distance of Keppel DC Singapore 2 and 3 in Tampines Industrial Park A. It follows the same carrier-neutral, purpose-built formula as KDC 3 — dedicated colocation suites backed by 24/7 technical support — and Keppel DC REIT now fully owns the asset. Certification coverage mirrors the portfolio standard at its strongest: BCA Green Mark Platinum and LEED Gold for environmental design, the eight-standard ISO suite spanning quality, environment, information security, privacy, anti-bribery, safety, water and energy management, plus SS 507, SS 564, the IMDA Data Protection Trustmark and PUB Water Efficient Building status. Keppel does not publish per-facility power, space or rack numbers. The location logic is cluster economics: tenants can spread workloads across three interconnected buildings in one industrial park, which appeals to cloud providers and enterprises engineering intra-campus redundancy in eastern Singapore.
