MTM Network Pole Inspection Project
Comprehensive inspection of 9,000 poles across the Metro Trains Melbourne network, covering timber, concrete, and steel infrastructure. Sterling provided detailed condition assessments, structural integrity testing, and preservation treatment to support MTM's asset management program.
Challenge
Metro Trains Melbourne required a comprehensive condition assessment of 9,000 poles across their network to support asset lifecycle management and safety compliance. The project involved inspecting diverse pole types (timber, concrete, steel) in live rail environments with overhead high voltage equipment. Work had to be conducted safely within active rail corridors, requiring coordination with train operations and strict compliance with electrical safety protocols. The inspections needed to be completed efficiently while maintaining detailed digital records and photographic evidence for each asset, all while managing the risks of working near live electrical infrastructure and operational railways.
Solution
Sterling deployed four specialized inspection teams, each led by qualified Site Managers with Rail Safety Worker credentials, working under Track Force Protection Coordinator supervision. The methodology involved systematic visual inspections, timber pole drilling at the 200mm line using specialized equipment to assess goodwood depth, and installation of Preschem preservation rods. For concrete and steel poles, teams conducted visual inspections and exposed footings to assess condition. All data was captured digitally using Fulcrum tablets with integrated GPS, ensuring compliance with MTM inspection forms. Work was coordinated around live rail operations, with strict adherence to safeworking protocols and electrical safety procedures when working near overhead 25kV equipment.
Deliverables
Sterling delivered comprehensive digital inspection records for 9,000 poles across the MTM network, including GPS-tagged condition assessments, structural integrity ratings, and photographic documentation. Each pole was classified with appropriate designations (serviceable, limited life, or unserviceable) based on measured goodwood depth and structural condition. Detailed defect reports identified repair and replacement priorities with grading for asset planning. All timber poles received Preschem preservation treatment and were tagged with inspection dates. The project provided MTM with a complete asset condition dataset to inform maintenance scheduling, capital planning, and network safety management.
Outcome
The project successfully delivered a complete condition baseline for MTM's pole infrastructure, enabling data-driven asset management decisions. Sterling's systematic approach ensured all 9,000 poles were inspected without disruption to train operations, maintaining MTM's service reliability while improving asset visibility. The digital capture methodology provided MTM with searchable, GPS-referenced inspection data integrated with their asset management systems. Poles requiring urgent attention were identified and prioritized, supporting proactive maintenance planning. The project demonstrated Sterling's capability to deliver large-scale rail infrastructure assessments safely and efficiently in live operational environments.
