Data Centre Construction and Turnkey Delivery

• Shell and core arrangement, partition walls and fire-rated compartments (EI 60 / EI 120)
• Raised floor system: load capacity calculation, antistatic finish, cable and air plenum arrangement
• Suspended ceiling, air return plenum and sealing applications
• Fire- and water-resistant security room solutions (EN 1047-2 / ECB-S certified modular room alternative)
• Security doors, mantraps and armoured door installations
• Waterproofing, vapour barrier and floor levelling
• Special rooms requiring electromagnetic (RF) shielding
• Fire-stop and sealed transit elements at cable penetrations

The majority of data centre availability is determined by the design and implementation quality of the electrical infrastructure. ONGSEC engineers, installs and tests the entire chain from the medium-voltage entry point to the socket at rack level.

• Medium-voltage switchgear, dry or oil-type transformer installation and protection coordination
• Main distribution panel (MDP), sub-distribution panels and power factor correction systems
• Automatic transfer switch (ATS) and static transfer switch (STS) applications
• Selectivity and short-circuit calculations, protection device coordination study
• Harmonic analysis, active/passive harmonic filters and power factor correction

• UPS selection and installation: online double-conversion, modular/scalable, parallel-redundant architectures
• Battery system design (VRLA / Li-ion), autonomy calculation, battery room ventilation and monitoring
• Diesel generator plant: sizing, synchronisation, parallel operation, load transfer scenarios
• Fuel storage, day tank, transfer system and fuel quality management
• Generator exhaust, silencer, vibration isolation and noise control
• Full-load and step-load testing with load banks

• Selection and installation of busbar or cable-type distribution
• Rack PDUs: metered, switched and outlet-metered models
• A/B dual-feed architecture and phase balancing
• Monitoring energy consumption at rack and outlet level and feeding it into DCIM

• Earthing network, equipotential busbar system and measurement/reporting
• Lightning protection system (air terminals, down conductors) and surge protection (SPD) stages
• Lighting design, emergency lighting and wayfinding luminaires
• Labelling and documentation of electrical rooms and cable shafts

• Addressable fire detection panel, optical/thermal detectors and cross-zoning logic
• Gaseous suppression: FM-200 (HFC-227ea), NOVEC 1230 and inert gas (IG-55 / IG-541) alternatives
• Discharge quantity and hold time calculation, room integrity (door fan) test
• Pressure relief damper calculation and installation
• Fire scenario programming: shutting down cooling, closing dampers, releasing doors, announcement and alarm integration
• Design and acceptance testing to TS EN 15004 and NFPA 2001
• Periodic maintenance, cylinder weighing checks and certified refill coordination

• Zone and spot water leak detection cable / sensor installation
• Temperature and humidity sensors positioned per ASHRAE recommendations (rack bottom/middle/top)
• Differential pressure, airflow and door status sensors
• DCIM / BMS integration, threshold values and alarm hierarchy definition
• Alarm routing integrated with SMS, e-mail and SOC/NOC

• Multi-layered access architecture: site → building → white space → rack level authorisation
• Card, PIN and biometric access control, anti-passback and two-person rule
• Mantrap, turnstile and armoured door applications
• CCTV system: corridor, door, rack row and perimeter camera placement, retention period calculation
• Electronic locks at rack level and door opening logging
• Visitor management, escort rules and access record archiving procedures

• Rack and cabinet supply, installation, fixing and seismic bracing
• Hot aisle / cold aisle containment systems, roof and door applications
• Blanking panels and brush grommets to control air leakage
• Copper and fibre backbone cabling, MPO/MTP cassette and trunk solutions
• Patch panels, cable managers and colour-coded labelling standard
• Cable testing and certification, delivery of measurement reports and manufacturer warranty application

The most frequently skipped stage in data centre projects is integrated testing of systems under real load. ONGSEC applies a staged commissioning methodology and delivers the output of each stage in writing.

• Level 1–2: factory acceptance tests (FAT) and site delivery checks
• Level 3: post-installation static checks, insulation and continuity measurements
• Level 4: component-based functional tests (UPS, generator, cooling, fire, access control)
• Level 5: integrated systems test (IST) — step load with load banks, utility failure and fault scenarios
• Black building test: verifying facility behaviour under total loss of supply
• Thermal imaging scan of connection points and reporting
• Cooling performance test, airflow measurement and temperature mapping
• Punch list management and closure against acceptance criteria

• Engineering and installation of prefabricated modular data centre solutions
• Container-type mobile data centres for field, temporary facility or disaster scenarios
• Single-rack or micro data centre cabinets with their own cooling, UPS and fire systems
• Replicating remote-site and branch edge data centres from a standard template
• Remote monitoring and lights-out operating architecture

• As-built drawings (architectural, electrical, mechanical, extra-low voltage) and current single line diagrams
• Operation and maintenance manual (O&M), equipment catalogue and warranty documents
• Standard operating procedures (SOP), maintenance procedures (MOP) and emergency procedures (EOP)
• Recording capacity and asset inventory into the DCIM system
• On-site handover training for the operations team and scenario-based drills
• Definition of periodic maintenance and fault response scope during the warranty period
