Engineering Services

Reliable, resilient power supply is the defining engineering challenge in data centre design.

• UPS system design — N, N+1, 2N redundancy configurations
• HT/LT power distribution — substation sizing, ring main unit, transformer specification
• Generator sizing and fuel storage — N+1 or 2N diesel/gas backup
• Automatic transfer switching (ATS) and static transfer switch (STS) specification
• PDU (Power Distribution Unit) design and branch circuit layout
• Busbar trunking system (BTS) design for floor-level power distribution
• Load schedule and maximum demand calculation (ETAP)
• Power monitoring system — branch circuit monitoring, DCIM integration

Precision cooling keeps servers within thermal parameters — designed and modelled before construction begins.

• Chilled water system design — primary/secondary/tertiary loops, variable primary flow
• CRAC/CRAH unit selection and placement for hot aisle/cold aisle containment
• In-row cooling and overhead cooling for high-density server racks
• Cooling tower and chiller plant design — free cooling integration
• CFD thermal analysis — identifying hotspots before build
• Containment system design — HAC or CAC
• Airside economiser design and free cooling hours calculation
• Chilled water pipe sizing and pump selection — variable flow systems
• DOAS (Dedicated Outside Air System) for fresh air and humidity control

Data centre fire suppression must protect equipment without water damage — every system hydraulically calculated to NFPA standards.

• Clean agent systems — FM-200 (HFC-227ea), Novec 1230 (FK-5-1-12)
• Inert gas systems — INERGEN, Argon, IG-541 (NFPA 2001 compliant)
• CO₂ system design for UPS rooms and high-value equipment spaces (NFPA 12)
• VESDA aspirating smoke detection system layout
• Water mist system design as alternative to gaseous suppression (NFPA 750)
• Pre-action dry pipe sprinkler system for IT halls
• Hydraulic calculations for all fire suppression systems to NFPA standards
• Fire pump sizing and system design — NFPA 20

Fully coordinated REVIT BIM models eliminating design clashes before construction.

• REVIT MEP model — power, cooling, fire protection, containment in single coordinated model
• Clash detection and interference checking — multi-discipline RFI reduction
• Cable management system design and routing — overhead trays, raised floor pathways
• Containment system coordination — hot aisle/cold aisle within REVIT model
• Coordinated drawings — ceiling plans, riser diagrams, section views
• Material take-off (MTO) generation for procurement and tendering

PUE reduction directly reduces operating cost and improves sustainability metrics.

• PUE baseline calculation and target PUE modelling
• Cooling efficiency improvement — partial load performance, economiser hours
• Power system efficiency — UPS efficiency curves, transformer losses
• Lighting and ancillary load reduction
• DCIM integration strategy
• ISO/IEC 30134 energy efficiency metric reporting
• Annual energy cost model — full year simulation including seasonal variation
