Post-handover civil, structural and architectural works delivered in live environmen
Operational data centres require more than routine upkeep. Planned maintenance, asset replacement, plant changes, tenant-driven modifications and small-scale upgrades all create the need for disciplined civil, structural and architectural works after handover. Larget supports data centre maintenance, refurbishment and live works with controlled delivery in operational environments.

Our role is to deliver maintenance-led works safely around access restrictions, permits, live services and maintenance windows. We support civil, structural and architectural (CSA) interventions at the interface between structure, building fabric, partitions, access systems and the physical requirements of MEP upgrades. From survey and design support through supply, logistics and installation, we deliver installation-ready packages with documented QA/QC, as-built updates and clear handover information for FM and operations teams.

Typical maintenance, refurbishment and live work scopes

• maintenance-driven repairs and local replacement works
• refurbishment works in plant areas, service zones and operational spaces
• tenant change works and reconfiguration of technical corridors or Data Hall interfaces
• new penetrations, openings and local structural modifications required for maintenance or upgrade activities
• replacement or modification of partitions, ceilings, panels and separation zones
• access improvements for inspection, servicing and safe maintenance routes
• containment and protection measures in plant and electrical areas
• quick-turn works aligned to maintenance windows and strict live-site controls

What we deliver
We provide installation-ready packages planned for live campuses, operational constraints and maintenance-led execution.

Structural and building fabric works

• secondary steelwork, supports, frames and local strengthening
• access platforms, walkways and maintenance structures
• sandwich panel modifications, internal separations, technical ceilings and partitions
• local repairs to building fabric, interfaces and finishes

Penetrations and compartmentation interfaces

• cable and pipe penetration solutions, including cowls and Roxtec systems where specified
• fire-stopping and compartmentation details aligned to site requirements
• moisture protection and sealing at critical interfaces

Plant-area and containment support

• drip trays and liquid containment in oil, water or glycol risk areas
• protective barriers and separation zones around chillers, CRAH / CRAC units and generators
• airflow-control elements where required, including air curtains, canopies and vent-circulation walls

Security and controlled-access zones

• mesh partitions and cages, access-control posts and modular enclosures
• modifications and extensions matched to operational layouts and maintenance access routes

How we work in live operational environments
Maintenance works in live data centres require discipline, sequencing and clear interface ownership. Our method is built around:

• scope definition with clear deliverables and inspection points
• access planning, lifting routes, permit-to-work alignment and safe execution
• sequencing around maintenance windows, outages and operational constraints
• documented QA/QC, as-built updates and handover information for FM and operations
• survey, model-based checks or 3D scanning / reverse engineering where required to verify existing conditions before fabrication

What the owner, developer or tenant receives

• installation-ready components and packages with defined interfaces
• documentation aligned to site standards, including QA/QC records and traceability where specified
• clear handover information supporting safe operation, maintenance and future changes
• practical engineering input that helps reduce rework and control downtime
