Mission-critical infrastructure, delivered without downtime

Power, precision cooling and monitoring for colocation, enterprise and carrier-landing facilities — including works executed inside live halls with tenant equipment in service.

Scope of works

From the incoming supply to the rack

A data centre fails at its weakest dependency — usually an interface between two packages. We carry the electrical chain, the thermal chain and the monitoring layer as one system.

Power & Redundancy

MV and LV distribution, switchgear, UPS and static transfer, generator connection, busway and rack-level distribution — built to the facility's redundancy topology.

Data hall aisle containment and precision cooling delivered by Mecamac
Thermal

Precision Cooling & Containment

CRAC and CRAH deployment, chilled water to the hall, hot and cold aisle containment and airflow management.

Monitoring

DCIM, EPMS & BMS

Branch-circuit monitoring, rack and aisle sensing, and integration into DCIM, EPMS and BMS — so capacity is managed on data, not assumption.

Detection & Suppression

Very early smoke detection, gaseous suppression interfaces and leak detection under raised floors and chilled water routes.

Topology

Two paths. Neither one blinks.

Concurrent maintainability is a design decision, not a maintenance promise. Either path can be worked on with the load still running.

Operating discipline

Anyone can build on an empty slab

Delivering inside an operating hall — where one wrong isolation costs an SLA penalty — is a different discipline. It is the one we are known for.

PlanningMethod & PhasingEvery activity planned against live operations, with agreed maintenance windows, isolation sequences and rollback positions before work begins.
PermitsChange ControlWork executed under the operator's change-management and permit regime, with risk assessed at task level and approvals recorded.
ContainmentDust & VibrationPhysical segregation, dust suppression and vibration control to protect live equipment during construction activity.
RedundancySingle-Path DisciplineWork sequenced so that redundancy is never reduced below the agreed threshold, with concurrent-maintainability preserved.
VerificationIntegrated TestingFailure-mode and load-bank testing that proves the design intent under fault conditions, not only under normal operation.
HandoverOperational ReadinessAs-builts, asset registers, single-line diagrams and operator training so the facility team can run what we installed from day one.

Technical questions

Design intent, redundancy & assurance

Which design standards and redundancy topologies do you work to?

We deliver to the design intent set by the facility owner and their consultant — commonly Uptime Institute tier objectives and TIA-942 infrastructure classification. Executed topologies include N+1 and N+N electrical and mechanical configurations with concurrent maintainability as a design requirement rather than an afterthought.

How do you execute works inside an operating hall without service interruption?

Through phasing plans agreed with facility operations, work executed under the operator's permit and change-control regime, physical containment against dust and vibration, and sequencing that never reduces redundancy below the agreed threshold. Every activity has a defined rollback position before it starts.

What does your commissioning process cover?

Staged commissioning through factory acceptance testing, site acceptance testing, and integrated systems testing. IST includes load-bank verification at design load and failure-mode simulation — utility loss, generator start, UPS transfer and cooling failure — so the facility is proven under fault conditions before energisation for live load.

How is cooling capacity matched to rack density?

Through airflow management rather than raw tonnage. We assess rack-level heat rejection, containment strategy and supply-air temperature policy together, because oversupplying cold air into an uncontained hall wastes energy without solving hotspots. Where densities vary across the hall, cooling is zoned accordingly.

Can you interface with the client's existing DCIM or EPMS platform?

Yes. Branch-circuit and environmental monitoring is delivered with the point schedule and protocol required by the client's existing platform. Where no platform exists, we can propose and integrate one, with the monitoring architecture designed for the facility's eventual capacity rather than only its first phase.
