Overview

Maintain, troubleshoot, and upgrade building automation systems in large facilities.

Key Responsibilities

• bas commissioning
• system integration
• preventive maintenance
• emergency support
• safety compliance
• coordination

Tasks

Safety & Compliance• Follow safety protocols, lockout/tagout (LOTO), electrical safety, and work in mechanical/electrical rooms safely.• Ensure compliance with applicable codes, standards, and regulatory requirements. Commissioning, Startup & Testing• Perform system startups, sequence testing, and functional checks for new installations or renovated systems.• Verify performance against design intent and sequence logic; ensure system stability.• Support acceptance testing and training of operations / maintenance staff on BAS usage. Coordination & Collaboration• Work with campus engineers, HVAC mechanics, electricians, IT/network staff, contractors, and vendors.• Participate in project planning, scope reviews, cost estimates, and field evaluations.• Assist with equipment replacement, capital projects, and facility expansion as needed. Must sometimes lift and carry equipment or tools (e.g. up to 50 lbs or per institutional policy). Some travel among campus sites may be required. System Integration & Upgrades• Assist with retrofits or upgrades of older control systems to modern BAS platforms.• Interface BAS with other systems — e.g. energy management, lighting controls, security or fire alarm systems.• Support connectivity, communication protocols (BACnet, Modbus, LonWorks, etc.), and network infrastructures. Preventive & Predictive Maintenance• Execute scheduled preventative maintenance tasks, inspections, and health checks.• Monitor trends and logs, identify anomalies, perform root cause analysis, and recommend corrective actions.• Maintain documentation: record configuration changes, wiring changes, software updates, work orders, and as-built drawings. Emergency & On-call Support• Provide after-hours or on-call support for urgent BAS / controls issues to minimize downtime or system failures.• Respond promptly to system alarms or infrastructure failures (HVAC, chillers, boilers, etc.). -Safety & Compliance• Follow safety protocols, lockout/tagout (LOTO), electrical safety, and work in mechanical/electrical rooms safely.• Ensure compliance with applicable codes, standards, and regulatory requirements. -Commissioning, Startup & Testing• Perform system startups, sequence testing, and functional checks for new installations or renovated systems.• Verify performance against design intent and sequence logic; ensure system stability.• Support acceptance testing and training of operations / maintenance staff on BAS usage. -Coordination & Collaboration• Work with campus engineers, HVAC mechanics, electricians, IT/network staff, contractors, and vendors.• Participate in project planning, scope reviews, cost estimates, and field evaluations.• Assist with equipment replacement, capital projects, and facility expansion as needed. -Must sometimes lift and carry equipment or tools (e.g. up to 50 lbs or per institutional policy). -Some travel among campus sites may be required. -System Integration & Upgrades• Assist with retrofits or upgrades of older control systems to modern BAS platforms.• Interface BAS with other systems — e.g. energy management, lighting controls, security or fire alarm systems.• Support connectivity, communication protocols (BACnet, Modbus, LonWorks, etc.), and network infrastructures. -Emergency & On-call Support• Provide after-hours or on-call support for urgent BAS / controls issues to minimize downtime or system failures.• Respond promptly to system alarms or infrastructure failures (HVAC, chillers, boilers, etc.). -Preventive & Predictive Maintenance• Execute scheduled preventative maintenance tasks, inspections, and health checks.• Monitor trends and logs, identify anomalies, perform root cause analysis, and recommend corrective actions.• Maintain documentation: record configuration changes, wiring changes, software updates, work orders, and as-built drawings. -BAS System Maintenance & Repair• Install, configure, program, and commission BAS controllers, sensors, actuators, valves, and related hardware.• Diagnose and repair faults in control loops, network communication, field devices, and equipment.• Calibrate sensors (e.g. temperature, pressure, humidity) and verify accuracy regularly.• Tune PID loops and ensure optimal system control response.• Respond to BAS alarms, events, and trends to proactively prevent system issues.
