The AMHS track wiring and power-up scope typically includes, but is not limited to, the following work:
Installation, support, and termination of bus bar and conductor systems feeding Muratec OHT/OHS track segments.
Pulling and terminating 480V / 208V / 120V power feeders from designated panels to AMHS power supply units (PSUs) and track power injection points.
Low-voltage controls, communication, and signal cabling (CAN bus, Ethernet/Profinet, fiber where applicable) between track segments, controllers, OCS (OHT Control System), and host MES interfaces.
Grounding and bonding of track structure, support steel, and equipment per Muratec specs and NEC Article 250.
Coordination of cleanroom-compatible cable management, including UPW-rated cable tray, stainless hardware, and approved penetrations through cleanroom walls and ceilings.
Pre-energization checkout, megger testing, point-to-point continuity, phase rotation, and documented commissioning support alongside Muratec start-up engineers.
Safe energization (power-up) of track sections in coordinated sequence with Muratec, including LOTO management and arc-flash precautions.
Field Leadership & Crew Management
Lead, schedule, and direct a crew of journeyman electricians, apprentices, and electrical foremen across multiple shifts as project demands.
Conduct daily pre-task planning (PTP) meetings, JSAs, and stretch-and-flex; ensure every crew member understands the day's scope, hazards, and quality expectations before entering the cleanroom.
Mentor and develop foremen and journeymen; identify training gaps and coordinate with the PM on corrective skill-building.
Manage labor productivity, track installed quantities against budget, and provide accurate weekly progress reporting to the PM.
Enforce gowning, contamination-control, and tool-control protocols at the cleanroom airlock and at all times within the controlled environment.
Technical Expertise & Subject Matter Authority
Serve as the on-site technical authority for AMHS electrical work, interfacing directly with Muratec field engineers, MEP design engineers, the owner's facilities team, and the GC.
Read and interpret Muratec OHT/OHS installation drawings, single-line diagrams, panel schedules, ladder logic, and controls schematics; translate engineering intent into precise field execution.
Resolve field conflicts, RFIs, and scope ambiguities; drive technical decisions in real time without compromising safety, quality, or schedule.
Verify track segment power requirements, voltage drop calculations, feeder sizing, and overcurrent protection coordination match approved drawings before any installation begins.
Lead troubleshooting on energized and de-energized systems — power quality issues, comm faults, ground loops, intermittent track faults — using meggers, oscilloscopes, multimeters, and clamp meters.
Cleanroom Protocol & Contamination Control
Champion cleanroom discipline: garmenting, glove protocol, tool wipedown, material staging, and approved ingress/egress procedures.
Ensure all materials entering the cleanroom are wiped down, certified, or otherwise approved per the site's contamination control plan (CCP).
Coordinate with the cleanroom certification team to maintain ISO classification during active electrical installation; understand the impact of cutting, drilling, and cable pulling on particle counts.
Use only cleanroom-compatible tools, lubricants, and consumables; reject any non-approved materials at the airlock.
Train and re-train crew on protocols whenever new personnel rotate onto the project.
Safety Leadership
Own the electrical safety program for the scope: enforce NFPA 70E compliance, arc-flash PPE selection, approach boundaries, and energized work permits where applicable.
Manage Lockout/Tagout (LOTO) program for the AMHS scope, including group lockout coordination during multi-trade interface work and Muratec commissioning.
Conduct and document daily safety inspections; lead near-miss and incident investigations with root cause analysis and corrective actions.
Reinforce slip/trip/fall awareness, ladder safety, scaffold and lift operation, and overhead work protocols — all elevated risks given AMHS track is overhead-mounted work.
Maintain a visible, vocal safety presence: stop work without hesitation when conditions warrant, and back the crew when they do the same.
Quality Assurance & Documentation
Verify every termination, splice, and pull against the approved drawings and Muratec installation specifications before sign-off.
Maintain installation records, megger logs, torque records, continuity checks, and as-built redlines daily — not at the end of the project.
Lead pre-energization walkdowns with QA/QC, the owner, and Muratec representatives; close out punch lists promptly.
Document and escalate non-conforming work to the PM with proposed remediation; never bury a quality issue.
Support commissioning documentation: power-up sequence records, factory-acceptance test (FAT) and site-acceptance test (SAT) participation, and final turnover packages.
Coordination & Communication
Interface daily with the GC, MEP coordinator, BIM team, and other trades (mechanical, controls, AMHS mechanical install, ceiling grid, fire protection) to manage track-overhead congestion and sequencing conflicts.
Lead weekly look-ahead planning with the PM; identify constraints, material needs, and prerequisite work two to three weeks in advance.
Communicate clearly and professionally with Muratec engineers — many of whom may be working through translation; use drawings, photos, and concise written confirmation to eliminate ambiguity.
Provide accurate, timely status updates to the PM and client representatives; flag risks early.
