Critical Environments
Where operational
continuity is
non-negotiable.
Why We Build Critical Environments
Critical infrastructure
demands zero compromise
Data centres, substations, and energy infrastructure operate under conditions where any disruption to the live environment carries consequences far beyond the construction site. These facilities demand contractors who understand permit-to-work regimes, operational continuity, and the zero-tolerance standards that govern critical infrastructure.
Conroy delivers for data centre operators, grid operators, private wire developers, and EPC partners — as general contractor or within integrated delivery teams.
AI compute workloads, cloud migration, and enterprise digital infrastructure are driving sustained demand for data centre construction across Ireland and Europe. Hyperscale campus expansion, colocation capacity growth, and edge deployment are creating a multi-year pipeline of new-build, retrofit, and campus civil works — requiring contractors with proven live-environment delivery capability.
EirGrid's grid development programme, ESB Networks infrastructure investment, and Ireland's renewable energy targets are driving significant demand for substation construction, grid connection civil works, and transmission infrastructure. This pipeline requires contractors experienced in delivering under HV safety rules and within EPC delivery frameworks.
Ireland's installed base of operational data centres generates a sustained, recurring pipeline of capacity upgrades, life-cycle replacements, and white space fit-out. This work is delivered on live campuses where operational continuity is maintained throughout — a distinct construction discipline from new-build delivery.
Ireland's renewable energy targets and grid balancing requirements are driving a substantial BESS pipeline. Battery storage facilities require civil works, specialist foundations, fire suppression infrastructure, and grid connection — delivered within EPC frameworks to compressed programme timelines aligned with grid energisation dates.
Large energy consumers — data centres, manufacturing campuses, and industrial facilities — are investing in dedicated power infrastructure to secure supply and manage cost. Private wire developments, on-site generation, and dedicated grid connections are creating a distinct construction pipeline of substation buildings, power distribution infrastructure, and campus-wide civil works.
What We Build
Six facility types.
One delivery standard.
Small MW data hall construction, power infrastructure buildings, and campus civil works. Delivered as general contractor with full CSA and MEP integration on greenfield and brownfield sites.
HAC/CAC corridor works, structural grid modifications, raised access floor and floor void works, white space fit-out, and facility expansion on operational campuses. Life-cycle replacements and capacity upgrades delivered under full permit-to-work regime without disruption to live operations.
Civil and structural works for GIS and AIS substations. Delivered under ESB/EirGrid safety rules as general contractor or within EPC delivery teams.
Battery energy storage system enclosures, foundations, fire suppression infrastructure, and grid connection civil works. Delivered within EPC frameworks to compressed programme timelines.
Grid connection civil works, renewable energy foundations, and generation plant buildings. Programme and site works co-ordinated with grid operators, equipment suppliers, and DNO/TSO inspection milestones.
Standalone control rooms, relay rooms, SCADA buildings, and MV/LV switch rooms. Precision-built enclosures for sensitive electrical and communications equipment with environmental control and EMC shielding.
What We Build — Technical Specification
The numbers
that govern delivery
Every specification below is established at Stage 2 and locked into the design brief — ensuring consistency from design through to delivery.
Reinforced concrete for data halls — thermal mass, vibration performance, and fire rating. Steel frame for power buildings and generator enclosures. Precast where programme speed is the priority. Structural grid designed around rack layout and equipment positions.
Reinforced slab design for server rack, battery array, and transformer point loads. Ground-bearing or pile-supported to suit ground conditions. Load schedule co-ordinated with equipment suppliers from Stage 2.
Civil and structural works for the full power chain — HV switchgear rooms, transformer compounds, generator enclosures, UPS rooms, and busbar risers. Interface with M&E contractors co-ordinated from pre-construction through to commissioning.
CRAH unit bases, chiller plant pads, pipework risers, and hot/cold aisle containment civils. Civil interface with the mechanical contractor co-ordinated to protect the cooling commissioning programme.
How We Deliver
Operational continuity
is the baseline
Construction on live data centre campuses, high-voltage substations, and energy infrastructure sites demands permit-to-work discipline, method statement rigour, and absolute programme certainty. Our delivery model is built around maintaining operational continuity throughout.
Construction methodology, programme sequencing, and logistics planned around operational continuity of the live environment. Permit-to-work regime, isolation procedures, and method statements developed during pre-construction. Package procurement, long-lead identification, and BIM co-ordination completed before mobilisation — ensuring programme certainty from day one.
Structural steel, precast concrete, cladding, and fire suppression systems are procured early — before design is finalised on secondary packages. Lead times on these items govern the programme. We identify, price, and place orders on long-lead packages during pre-construction to protect the critical path from day one.
4D programme developed at appointment and maintained throughout. Target cost plan with risk-weighted allowances and formal change control. Programme updated weekly from site data, cost reported monthly, and the anticipated final account maintained as a live document — giving the client full visibility at every stage.
Director-led site delivery with dedicated management and structured quality inspections throughout. Interface between construction works and live operations managed through formal isolation procedures, permit-to-work co-ordination, and method statements reviewed and approved before every critical intervention.
Structured digital handover — O&M manuals, as-built drawings, BIM model, and COBie data formatted for FM integration. Integrated systems testing and commissioning support co-ordinated with the client's operations team. 12-month defects liability period with active management.
