Site Technician

A Building Automation System (BAS) / BMS Site Technician is the person on-site who makes sure all the automated building systems actually work as designed. You are the bridge between the office design team, the main contractor, and the on-site installation.

Here is the basic job scope:

Site Installation & Supervision

• Supervise installation of BAS/BMS equipment: DDC controllers, sensors, actuators, control panels, field devices, networking cables.

• Check that installation follows approved shop drawings and method statements.

Testing, Commissioning & Troubleshooting

• Perform point-to-point testing: I/O checking, sensor calibration, actuator stroke check.
• Perform system integration testing for HVAC systems - AHU, FCU, Chiller Plant, Cooling Towers, Exhaust Fans, etc.
• Troubleshoot faults on-site - hardware, wiring, or software logic issues.

Common Skills Required

• Technical: Knowledge of HVAC basics, electrical wiring, DDC controllers.
• Tools: Laptop with BMS engineering tools, multimeter, basic hand tools.
• Soft skills: Good communication, problem-solving, able to read electrical schematics & P&ID drawings, independent at site.

In short: You own everything BAS-related on site - from ensuring devices are installed correctly, to programming, testing, commissioning, and handing over a fully working smart building to the client.
