Mission-Critical & Telecom
Telecom and mission-critical sites carry the data-center obsession with uptime — redundant power, dedicated cooling, battery backup — into a smaller, distributed, often DC-powered footprint. We produce construction-ready resilient power, precise cooling, and battery infrastructure that central offices, network nodes, and 911 centers depend on to never go dark.
Continuity-Grade Power and Cooling, Distributed Footprint.
Telecom MEP is its own discipline: -48VDC power plants with rectifiers and battery strings, hydrogen ventilation that holds VRLA cells below the explosive limit, and cooling sized to Telcordia GR-3028 rather than a generic comfort spec. Every site balances AC standby, DC continuity, and tight cooling across a footprint where one failed component takes the network down — coordinated with your team and documented behind the seal of the licensed engineer of record on your project.


Resilient AC & DC Power
The dual-source power that keeps a network energized through any outage or maintenance window.
- Redundant utility service with standby generation and automatic transfer per NFPA 110
- -48VDC power plant sizing — rectifiers, battery strings, and DC distribution to the equipment line-ups
- UPS topology for AC critical loads, with concurrent maintainability where the site demands it
- Selective coordination, short-circuit, and arc-flash studies built into the documents
- Critical-load metering and monitoring for capacity and reserve-time tracking
Grounding, Bonding & Surge
The reference and protection scheme sensitive electronics live or die by.
- Common bonding network and isolated/integrated ground per Telcordia GR-1089
- DC return vs. telecom ground electrode vs. AC equipment ground — resolved by design
- Surge protective devices coordinated from service entrance to the rack
- Lightning protection and ground-ring coordination for tower and rooftop sites
- Equipotential bonding at cable entrance for overhead and underground facilities
Precise Cooling & Thermal
Dedicated cooling that holds the equipment envelope on a footprint with no thermal margin.
- CRAC/CRAH and in-row cooling sized to equipment heat release, per Telcordia GR-3028
- Front-intake, top-/rear-exhaust line-up airflow — the telecom convention, not data-center aisle containment
- Redundancy (N+1 / dual-unit) matched to the criticality of the site
- ASHRAE TC 9.9 thermal envelopes held across normal and economizer modes
- Equipment-room humidity control and condensate management for electronics protection
Battery Rooms & Energy Storage
Ventilation and protection sized to the chemistry, not assumed.
- Hydrogen ventilation holding VRLA cells below 1% by volume, or 1 cfm/sq ft continuous, per IFC/IMC
- Spill containment and acid-neutralization for flooded lead-acid strings
- Thermal-runaway detection and ventilation interlocks for VRLA systems
- Lithium-ion ESS ventilation, detection, and clearances per NFPA 855 where applicable
- Battery-room temperature control to protect string life and capacity
Fire Detection & Coordination
Telecom-specific fire protection coordinated with the suppression and network vendors.
- Air-sampling (VESDA-type) smoke detection for early warning in equipment spaces
- NFPA 76 fire-protection strategy for telecommunications facilities
- Clean-agent suppression coordination where the equipment value justifies it
- Leak detection under raised floor and near cooling units
- Cable-tray, riser, and equipment-line-up coordination with network and OEM vendors
Quick answers about how we deliver design support for this sector.
Both. We size the DC plant — rectifiers, battery strings, and DC distribution to the equipment line-ups — alongside the AC service, standby generator, and ATS. Telecom continuity rides on the DC bus, so we coordinate rectifier capacity and battery autonomy against the equipment load and the reserve time the site requires, then resolve the DC return and grounding reference per Telcordia GR-1089 — all behind the seal of the licensed engineer of record on your project.
By the chemistry. For VRLA strings we design ventilation to hold hydrogen below 1% by volume — or a continuous 1 cfm per square foot of floor — with thermal-runaway detection and interlocks per the IFC and IMC. Flooded lead-acid adds spill containment and acid-neutralization; lithium-ion ESS brings NFPA 855 detection, ventilation, and clearance requirements. The ventilation is sized to the actual battery system, not a generic allowance.
Yes. Central-office and telecom cooling follows Telcordia GR-3028 thermal management and the front-intake, top-/rear-exhaust line-up convention — not a generic comfort spec or data-center aisle containment. We size dedicated, redundant cooling to the equipment heat release and hold ASHRAE TC 9.9 envelopes across operating modes, because these footprints have almost no thermal margin when a unit drops offline.
Yes — these are among the most redundancy-critical sites we support. Dispatch centers need layered backup power, redundant cooling, and continuity through utility outages and component failures, often aligned with NENA facility guidance. We design the standby power, UPS, dedicated cooling, and monitoring so the center stays operational under the exact conditions it exists to respond to — coordinated with your team and the licensed engineer of record on your project.
Same uptime obsession, different footprint and power architecture. Telecom sites are smaller and distributed, frequently DC-powered, and governed by Telcordia GR-63/GR-3028/GR-1089 and NFPA 76 rather than only the data-center stack. Redundancy targets and cooling scale to how critical each node is — but a central office, network node, or 911 center is engineered with the same discipline as a compute hall.
