Execute and document corrective work orders using a CMMS, prioritize workload, estimate parts and labor needs, and follow up to ensure timely resolution and customer satisfaction.
Perform building envelope repairs including doors, windows, drywall, roofing penetrations, and weather sealing to maintain security, comfort, and energy efficiency.
Conduct routine facility inspections (rooftops, mechanical rooms, emergency exits, safety equipment) to identify hazards, code violations, and deferred maintenance items and initiate corrective actions.
Implement lockout/tagout, confined space, and other safety procedures during maintenance activities, ensure PPE use, and maintain compliance with OSHA and company safety policies.
Respond to emergency maintenance calls (after-hours, weekends) for critical equipment failures, floods, electrical outages, HVAC breakdowns, and coordinate rapid repairs to minimize operational impact.
Coordinate and supervise outside contractors and vendors for specialty work, review contractor scopes of work, verify completed work meets specifications, and ensure proper permit and safety compliance.
Maintain accurate parts and materials inventory, perform stock replenishment, and prepare purchase requests to support continuous maintenance operations.
Fabricate and install metalwork, brackets, guards, and ductwork, perform welding and brazing as needed to repair or modify equipment and building systems.
Test and calibrate instrumentation and control devices including thermostats, pressure sensors, temperature probes, and flow meters to ensure accurate system operation.
Manage energy and utility conservation initiatives by implementing efficient maintenance practices, recommending system upgrades, and monitoring energy use trends.
Perform preventive and corrective maintenance on life-safety systems (fire pumps, emergency lighting, exit signs) and coordinate with fire alarm service providers as required.
Maintain detailed maintenance records, create service reports, and communicate status updates to facilities management and building occupants to ensure transparency and accountability.
Provide training and mentoring to junior technicians and apprentices on best practices, safety procedures, diagnostic techniques, and company policies.
Inspect and service vehicle and powered equipment (forklifts, floor scrubbers, snow removal equipment) to ensure safe operation and availability for facility needs.
Conduct root cause analysis on repeat failures, recommend permanent corrective actions, and support capital planning by providing technical input for equipment replacement and upgrades.
Maintain compliance with environmental regulations related to refrigerants, hazardous materials, waste disposal, and chemical handling, and participate in periodic audits.
Support shutdowns and turnarounds by participating in planned outage activities, coordinating trades, executing complex repairs, and documenting scope completion.

Secondary Functions

Assist with minor renovation and project tasks including demolition, assembly, and finishing work to support facility improvement projects.
Support procurement by verifying vendor quotes, inspecting delivered materials for compliance, and advising on cost‑effective spare parts.
Contribute to facilities planning and budgeting by providing historical maintenance data, failure trends, and estimated life‑cycle costs of equipment.
Participate in cross‑functional teams for space moves, tenant improvements, and workplace safety committees.
Help develop and refine preventive maintenance schedules, checklists, and standard operating procedures to improve reliability and efficiency.
Provide on‑site consultation to occupants regarding basic equipment operation and energy conservation practices.
Assist environmental, health, and safety (EHS) teams with incident investigations and corrective action implementation when maintenance issues are causal factors.
Support emergency preparedness planning by identifying critical systems and participating in drills and contingency planning.
Maintain and update equipment asset registers and tagging for improved tracking and CMMS accuracy.
Participate in vendor selection and evaluation for specialized maintenance services, providing technical input and quality assurance.
