Testing, Adjusting, and Balancing (TAB)

Comprehensive TAB and System Commissioning Services

Our Testing, Adjusting, and Balancing (TAB) services are a cornerstone of our broader consulting on the construction, installation, commissioning, maintenance, and optimization of building systems. We ensure all MEP and Fire Protection systems are tested and verified to operate at peak performance and meet all design specifications.

Mechanical Systems

The core of our TAB services focuses on ensuring the performance and efficiency of your mechanical infrastructure. We conduct detailed assessments and adjustments on a wide range of equipment.
  • Heating, Ventilation, and Air Conditioning (HVAC)
    • Boilers (Low and HP Boilers), chillers, heat pumps
    • Air handling units (AHUs), fan coil units (FCUs)
    • All Air and All water systems
    • Indoor Air Quality
    • Cooling Towers and Auxiliary equipment
    • Refrigerant Optimization.
    • Variable air volume (VAV) systems
    • Exhaust and makeup air systems, Dedicated Outdoor Air Systems
    • Fluid Handling Systems- Pumps, Fans, Blowers, Converters and Heat Exchangers
    • Testing Adjusting and Balancing of Air and Water Systems
    • Sump Pumps and Ejectors and Deep Well Pumps and Booster Systems
    • Dewatering Systems
    • Steam and Hydronics Systems Optimization
    • Domestic Hot Water Systems
  • Building Automation Systems (BAS)
  • Energy Recovery Ventilators (ERVs) / Heat Recovery Ventilators (HRVs)
  • Ductwork and air distribution systems
  • Refrigeration systems (for cold storage or process cooling)
  • Smoke control and stair pressurization systems
  • Boilers and Pressure Vessel Testing, Condition Assessment- Done by Certified National Board Boiler and Pressure Vessels Inspectors

Electrical Systems

While not traditional “balancing,” the testing and commissioning of electrical systems are vital for ensuring safety, efficiency, and reliability as part of a whole-building assessment.
  • Electrical Service Upgrades – Load Letters
  • Main service switchgear and distribution panels
  • Transformers and substations
  • Emergency power systems (generators, UPS)
  • Lighting systems (interior, exterior, emergency)
  • Lighting controls and occupancy sensors
  • Receptacle and branch circuit wiring
  • Fire alarm and detection systems
  • Lightning protection and grounding systems
  • Telecommunications and data systems
  • Security and access control systems
  • Electric vehicle (EV) charging infrastructure
  • Renewable energy systems (solar PV, wind, battery storage)

Plumbing Systems

Our TAB principles extend to plumbing through precise flow rate and pressure testing, ensuring systems operate efficiently and reliably.
  • Domestic cold and hot water supply
  • Sanitary waste and vent systems
  • Stormwater drainage and retention
  • Water heating systems (tank, tankless, solar)
  • Booster pumps and pressure-reducing valves
  • Backflow prevention devices
  • Greywater and rainwater harvesting system
  • Compressed air and vacuum systems (for labs and industrial use)

Fire Protection Systems

Testing and verifying fire protection systems is a critical life-safety service. We ensure that all components are balanced and functioning together to respond effectively in an emergency.
  • Fire sprinkler systems (wet, dry, pre-action, deluge)
  • Standpipe and hose systems
  • Fire pumps and controllers
  • Fire alarm and detection systems (smoke, heat, CO detectors)
  • Fire suppression systems (clean agent, foam, CO₂, kitchen hood)
  • Smoke control and evacuation systems
  • Fire-rated assemblies and firestopping
  • Emergency voice/alarm communication systems (EVACS)
  • Fire command center and annunciator panels
  • FDNY Letter of Approval
  • Kitchen Equipment Testing- Exhaust, Make Up air, TAB, Pressurization and Range Spillage Testing
