Transformer Replacement

Decommissioning and replacement of aging or inefficient electrical transformers to improve power quality and reduce energy loss.

Electrical Capacity Upgrade

Comprehensive upgrade of the facility's main electrical service and distribution systems to increase overall power capacity and support future growth.

UPS Generator SWGR Upgrade

Integrated upgrade project involving the interconnected system of UPS, generators, and switchgear to ensure seamless power transfer, fault tolerance, and system resilience.

Generator Systems Design, procure, install, and commission systems for higher-capacity, or more fuel-efficient units, including associated fuel systems and exhaust.

UPS Expansion Expansion of the existing UPS infrastructure to support additional critical loads, including the installation of new UPS modules, batteries, and downstream distribution panels.

A/B/C/D (MV and LV) Bus Mechanical Upgrades

Mechanical system upgrades to support redundant electrical distribution buses, potentially including dedicated cooling units, chilled water piping, and controls for each bus.

PDU Install Installation of new Power Distribution Units (PDUs), including the associated electrical connections and underfloor or overhead cooling provisions required for these units. Move to electrical

MECHANICAL

Condenser Water Filtration

Installation or upgrade of filtration systems (e.g., side-stream filters) for the condenser water loop to improve water quality, reduce fouling, and increase heat exchange efficiency.

Boiler & Expansion Tank

Replacement or refurbishment of existing heating boilers and associated expansion tanks to ensure reliable operation of the facility's heating water system.

IRC Installation Design, purchase, install, and commission In-Row Cooling (IRC) units within data center server rows to provide high-density, targeted cooling directly at the heat source.

Free Cooling Implementation or upgrade of a "free cooling" system (e.g., water-side or air-side economizer) to leverage favorable ambient conditions and reduce mechanical cooling energy consumption.

Rear Door Cooling Installation of Rear Door Heat Exchanger (RDHx) cooling systems on server cabinets to capture and neutralize server exhaust heat at the rack level.

Chiller/Tower Repair

Major repair, overhaul, or refurbishment of existing centrifugal or screw chillers and associated cooling towers to restore performance and extend service life.

Mechanical Capacity Upgrade

Comprehensive upgrade of the central cooling plant (chillers, pumps, towers) and distribution systems to increase the facility's overall cooling capacity.

CRAH/CRAC

Purchase & Install

Design, purchase, install, and commission Computer Room Air Handler (CRAH) units, including associated piping, controls, and commissioning, to support data center cooling requirements.

Aisle Containment Implementation of a hot or cold aisle containment strategy within the data center, including the installation of partitions, doors, and blanking panels to separate air streams.

AHU Replacement Replacement of aging or inefficient Air Handling Units (AHUs) serving office or support spaces, including ductwork modifications, controls integration, and commissioning.

Fuel Modification Modification of the existing diesel fuel system for backup generators, potentially including fuel polishing systems, day tank upgrades, or modifications for alternative fuel types.

Diesel Fuel Tank

Installation of a new bulk diesel fuel storage tank, including secondary containment, fuel piping, leak detection, fuel polishing, automatic redundant fuel pump control systems, and monitoring systems to support generator operations.

Hot Aisle Containment

A specific implementation of aisle containment that involves capturing and containing hot server exhaust air, preventing it from mixing with the cold supply air.

GENERAL INFRASTRUCTURE

Computer Rack Design, procure, and install server racks, cabinets, and associated hardware within a data center or computer room environment, including grounding and seismic bracing as required.

Cable Tray Install Installation of overhead or underfloor cable tray and ladder rack systems to support power, network, and low-voltage cabling infrastructure.

Furniture Design, procure, and install office furniture, including systems furniture (cubicles), seating, conference room furniture, and ancillary items.

Raised Floor Installation, modification, or expansion of raised access flooring systems, including structural supports, floor panels, and cutouts for cabling and airflow.

Entry Door Replacement

Replacement of interior and/or exterior doors, frames, and hardware. May include integration with security and access control systems.

Security System Installation or upgrade of physical security systems, potentially including Access Control Systems (ACS), CCTV surveillance cameras, intrusion detection systems, and monitoring stations.

BAS Upgrade Upgrade or modernization of the existing Building Automation System (BAS), including controllers, sensors, and the front-end user interface, to improve building efficiency and control.

MPDU

Procurement and installation of Modular Power Distribution Units (MPDUs), also known as rack PDUs, to provide and manage power at the server cabinet level.

OPERATIONS AND MAINTENANCE

Duct Cleaning

Comprehensive cleaning of HVAC supply, return, and exhaust ductwork systems in accordance with National Air Duct Cleaners Association (NADCA) standards. The work includes removing all dust, debris, and contaminants from the air distribution system to improve indoor air quality and system performance.

Water Test and Balance

Professional testing, adjusting, and balancing (TAB) of hydronic systems, including chilled water, heating water, and condenser water loops. The objective is to ensure that water flow rates meet the design specifications for all equipment and terminal units (e.g., coils, chillers, boilers).

Air Test and Balance

Professional testing, adjusting, and balancing (TAB) of HVAC air distribution systems. The work includes measuring and adjusting airflow at all supply diffusers, return grilles, and exhaust fans to ensure that all spaces receive the specified air quantities for proper ventilation and temperature control.
