Central plant torack face.
Eight scopes, self-performed. One contractor accountable for the whole cooling path instead of four subs pointing at each other.
Mechanical is the core trade
Air handling, equipment setting, and distribution. We rig it, set it, connect it, and balance it — the work the rest of the job gets built around.
- Air handling units, rooftop units, and make-up air
- Fan walls, in-row and computer room air handlers
- Equipment setting and rigging — chillers, pumps, exchangers, towers
- Ductwork fabrication and installation, low and medium pressure
- VAV boxes, dampers, louvers, and terminal equipment
- Exhaust, ventilation, smoke evacuation, and pressurization
- Duct sealing and leakage testing
- Refrigerant piping and split system installation
- Rotating equipment alignment and startup
- Test and balance coordination
Welded, tested, documented
Every mechanical system is only as good as the pipe carrying it. We weld it, test it, and document it in house — no subbed-out welding, no gaps in the paper trail.
- Carbon steel, stainless, copper, HDPE, and grooved / Victaulic systems
- Large-bore and small-bore, above ground and underground
- ASME B31.1, B31.3, and B31.9 scope
- Certified welders with current WPS and WQR on file
- Shop prefabrication — spools, pipe racks, pump skids, valve assemblies
- Weld mapping, NDE coordination, and full material traceability
- Hangers, supports, seismic bracing, expansion joints, and anchors
- Insulation coordination and jacketing
The plant, and everything downstream
Heat rejection is the whole job. We build the machinery that moves it and the piping that carries it.
- Air-cooled and water-cooled chillers, N+1 and 2N
- Plate-and-frame heat exchangers for waterside economizer and loop isolation
- Cooling towers, dry coolers, and adiabatic units, including basin piping and makeup
- Primary/secondary and variable primary pumping, headers, and bypass
- Expansion tanks, air separators, side-stream filtration
- Chemical treatment: pot feeders, glycol feed, corrosion coupon racks
Glycol is unforgiving
Wrong concentration, weak freeze protection, or an incomplete flush, and you find out in January or at 40% pump curve.
- Propylene and ethylene loops mixed and verified by refractometer, with batch records
- Freeze protection coordination, low-ambient sequencing, freeze-stat installation
- Dedicated glycol makeup and pressurization packages
- Full flush, passivation, and inhibitor charge before turnover
- Sampling and lab reporting at handoff, so operations starts with a known baseline
- Concentration verification at every seasonal changeover
Distribution and white space
Risers, mains, and every connection at the rack face — including the liquid cooling scope high-density deployments now demand.
- Large-bore risers, main loops, and floor distribution
- Isolation valve trees, flow measuring stations, pressure-independent control valves
- CRAH and CRAC hookups, condensate, and humidification piping
- CDU installation and manifold piping for direct-to-chip liquid cooling
- Rear-door heat exchanger connections and quick-disconnects
- In-row cooling, overhead and underfloor distribution
- Flexible hose drops and sub-floor piping
- Drip pan and leak detection cable coordination
Full MEP, one contract
Splitting M, E, and P across three contractors is how coordination gaps become change orders.
- Power distribution, feeders, branch circuits, and terminations
- Equipment connections for chillers, pumps, AHUs, and controls
- Conduit, cable tray, busway support, and grounding
- Lighting, emergency lighting, and lighting controls
- Domestic water, sanitary waste, vent, and storm
- Condensate, makeup water, and equipment drains
- Backflow prevention, water heaters, and pumps
- Controls, BAS, and instrumentation rough-in and coordination
Rack and stack
Cabinets set, anchored, aligned to the containment grid, and cabled — ready for first-article deployment.
- Cabinet delivery, staging, leveling, bolt-down, seismic anchorage
- Anti-tip anchoring completed before population
- Rack alignment to containment grid and floor tile layout
- Blanking panels, brush grommets, airflow sealing
- Receptacle and voltage verification prior to energization
- Structured cabling pathway, ladder rack, cable tray
- Fiber termination and splicing for first-article and initial operations turnover
- Coordination with electrical for busway tap-offs and rPDU mounting
Containment that actually seals
Cooling capacity is wasted the moment supply and return air mix.
- Hot aisle ceilings, roof panels, end doors, drop-away fire-rated panels
- Cold aisle containment and full-height end-of-row assemblies
- Chimney and ducted cabinet returns
- Air sealing at cable cutouts, floor penetrations, and rack gaps
- Raised-floor tile load verification and coordination
- Delta-T verification and airflow balancing to ASHRAE TC 9.9
