Mechanical main contractor · since 2007
Mechanical Contracting,
Delivered Off-Site First
We design, prefabricate and install boiler houses, plant rooms and pipework skids for main contractors across Ireland's most demanding sectors.
Who we are
A full mechanical contractor, built on control
Since 2007, Alert Mechanical has grown from a specialist installer into a full mechanical contractor trusted on some of Ireland's largest and most complex builds.
We work directly with main contractors, developers and end clients, bringing plant rooms, boiler houses and process pipework off the critical path and into a controlled factory environment before it ever reaches site.
About Alert Mechanical
What we do
Core offerings
Boiler Houses & Plant Rooms
Full design, build and commissioning.
Prefabricated Skids
Pipe rack and plant skid assemblies, factory-built and site-ready.
Containerised Systems
Modular plant solutions for constrained or live sites.
Mechanical Upgrades
Heating, ductwork and air conditioning upgrades to occupied buildings.
Why prefabrication
Built off site. Installed on time.
Traditional mechanical installation ties plant rooms and boiler houses to the critical path, so every delay on site becomes a delay to handover. Our prefabrication model builds and pressure-tests skids, boiler houses and pipe racks in a controlled environment, then delivers them to site ready to connect.
- Reduced site labour and site duration
- Fewer trades and less congestion on live sites
- Consistent quality control in a factory environment
- Faster, more predictable handover for main contractors
Sectors
Trusted where downtime is not an option
We deliver across sectors where compliance, precision and programme certainty matter most.
For main contractors
Working with main contractors, not just for them
Alert Mechanical operates as a main contractor in our own right on mechanical packages, taking on direct design and delivery responsibility rather than sub-contracting through a middle tier. If you are tendering a mechanical package or looking for a delivery partner who can prefabricate, install and commission to programme, we would like to talk.

Why we build mechanical packages off site
Off site first, on site fastMost mechanical contracting is built around site sequencing: trades stacked on top of each other, quality dependent on site conditions, and programme at the mercy of everyone else's delays. We approach it differently. Wherever a boiler house, plant room, pipe rack or plant skid can be built off site, we build it that way, in a controlled environment, to a fixed standard, tested before it ever leaves the workshop. It arrives on site ready to be positioned, connected...

Delivering mechanical works in live, occupied buildings
Upgrades without shutting the building downA significant part of mechanical work happens in buildings that stay in use throughout: schools, hospitals and commercial premises that cannot simply close for the works. We regularly deliver heating, ductwork and mechanical upgrade works to buildings that remain operational, planning installation around occupancy and access constraints. How we plan around occupancy* Phased installation that works around live operations and access windows *...

Working as a main contractor, not just for them
Direct design and delivery responsibilityAlert Mechanical operates as a main contractor in our own right on mechanical packages, taking on direct design and delivery responsibility rather than sub-contracting through a middle tier. We also partner with leading main contractors on larger programmes. That means clear accountability for our packages, from design through to commissioning and handover, without layers of sub-contracting in between. What this means for a tender* A single point of...
