BMS / Controls Commissioning Tech
Location: Singapore Employment Type: Full-Time Department: Engineering / Building Automation & ACMV Systems Role Summary We are seeking an experienced and detail-oriented BMS / Controls Commissioning Tech to lead the testing, field termination, programming, and commissioning of Direct Digital Control (DDC) panels and Building Management Systems (BMS). In this hands-on role, you will be the key technical driver bridging electrical/control hardware with supervisory software, ensuring our HVAC and commercial ACMV systems are fully integrated, optimized, and commissioned to the highest operational standards. Key Responsibilities
- Panel Termination & Hardware Verification
Perform and verify final control wiring, point-to-point terminations, and field device connections inside DDC control panels (sensors, actuators, VFDs, relays, and meters).
Conduct pre-commissioning checks, including loop checks, continuity, polarity, signal integrity (4–20 mA, 0–10 Vdc, PT1000/NTC), and power distribution verification.
Read and interpret control panel schematics, single-line diagrams (SLDs), mechanical HVAC layouts, and I/O point schedules.
- DDC Programming & Sequence of Operations (SOO)
Configure, modify, and fine-tune control logic/function block code for various HVAC equipment (AHUs, FCUs, chillers, cooling towers, primary/secondary pumps, and ventilation systems).
Implement and calibrate control loops (PID tuning for temperature, humidity, static pressure, and differential pressure).
Integrate field protocols and network buses seamlessly across subsystems (BACnet MS/TP, BACnet/IP, Modbus RTU/TCP).
- Supervisory BMS & Front-End Integration
Build, configure, and map graphics, alarms, trending, and schedules on enterprise-level BMS management platforms.
Validate third-party equipment communications (VFDs, power meters, chillers, packaged systems) to supervisory workstations.
Perform site testing and troubleshooting of network infrastructure (switches, IP subnets, routing, and communication gateways).
- Testing, Commissioning & Handover
Conduct formal Site Acceptance Testing (SAT), integrated building testing, and cause-and-effect matrix verification alongside clients, consultants, and main contractors.
Identify, isolate, and rectify wiring faults, hardware issues, communication drops, and programming logic errors on site.
Prepare comprehensive commissioning documentation, red-line markup drawings, point test sheets, and operation/maintenance handover reports.
Requirements & Qualifications Education: Diploma or Degree in Electrical Engineering, Mechanical Engineering, Building Automation, Instrumentation & Control, or equivalent practical experience.
Experience: 3+ years of direct, hands-on experience in DDC panel troubleshooting, field wiring/termination, and BMS commissioning for commercial HVAC/ACMV applications.
Protocol & Network Mastery: Solid working knowledge of open building protocols ( BACnet IP / MS/TP, Modbus RTU / TCP ) and basic IP networking (subnetting, addressing, routing).
Software Platforms: Strong familiarity with modern graphical, modular, or block-based DDC programming environments, as well as enterprise BMS front-end management suites (e.g., configuring dynamic user graphics, alarm priorities, time schedules, and historic trend logs).
Hands-On Skills: Proficient with electrical multimeters, signal generators/calibrators, network diagnostic tools (e.g., Wireshark/BACnet sniffers), and control hand tools for site terminations.
Troubleshooting Mindset: High aptitude for quickly breaking down complex issues across physical wiring, field sensors, controller firmware, and software logic.
Preferred Attributes Proven adaptability in learning and cross-platform configuring modern Tier-1 European or North American BMS hardware and enterprise supervisory suites.
Strong self-starter attitude with clear communication skills for coordinating on-site with mechanical sub-contractors, testing and balancing (TAB) teams, and project managers.
