Services

BAS and HVAC controls installation services

Division 25 controls installation: six services covering the physical side of a BAS or BMS, from the first cable pull to commissioning support.

01

Controls rough-in and cabling

Good controls work starts before the walls close. We set out pathways and pull control cable early, so devices land exactly where the drawings put them.

  • Conduit, sleeves, J-hooks and cable support
  • Control, sensor, communication and 24 V power cable pulls
  • Cable dressing, separation and support to specification
  • Continuity testing before close-in

Controller and field device installation

We mount and connect the hardware that measures and controls the building, on the platform your project uses.

  • Supervisory and field controllers, VAV and unitary controllers
  • Control panels and enclosures
  • Temperature, humidity, CO₂, CO/NO₂ and pressure sensors
  • Damper and valve actuators, transducers and relays, landed on the Class 2 side
  • Low-voltage thermostats and room sensors

03

Terminations and labelling

Terminations are where most controls problems hide. Every conductor is landed to the drawings and identified at both ends.

  • Terminations at controllers, devices, panels and relays
  • Wire and cable identification
  • Panel wiring dressed and tidy
  • Terminal and routing changes marked up for the as-builts
04

BACnet and Ethernet networks

Controllers only work as a system when the network is right. We install and test the communication cabling between them.

  • BACnet MS/TP trunks, daisy-chained and terminated
  • Ethernet cabling for BACnet/IP controllers and supervisory devices
  • Network cable labelling and routing records
  • Trunk polarity, shield and end-of-line resistor checks before start-up

Point-to-point checkout and commissioning support

Before anyone commissions a system, every point should be proven. We verify each input and output from the field device back to the controller.

  • Point-to-point verification of every input and output
  • Deficiency correction and re-test
  • Checkout records for the project file
  • On-site support for the controls technician and commissioning agent during start-up

Retrofits and upgrades

Retrofit work happens around occupants and live systems. We plan the sequence so the building keeps running while the controls change.

  • Removal and relocation of existing BAS wiring and devices
  • Controller and field device replacement
  • Bringing fan coils, meters and new equipment onto the system
  • Closeout documentation for the upgraded installation
