The Challenge
Sydney Metro’s upgrade of the T3 Bankstown Line required new boundary and security fencing along the corridor. The fencing was already built, but Sydney Metro’s review of the as-built state had flagged locations where the configuration did not satisfy Tests and Commissioning human factors criteria. The principal contractor needed an independent security assessment to determine whether each location was acceptable or required additional treatment — and a formal SFAIRP assurance statement to close the compliance requirement.
Our Approach
Core42 assessed each of the five locations individually against three primary hazard categories: trespass, thrown objects, and self-harm. Each site presented a distinct combination of fencing configuration, adjacency, road geometry, and natural surveillance, meaning a uniform corridor-wide recommendation would have either over-treated some sites or under-treated others. Where panel gaps were identified, each was assessed on its merits — at some locations, compensating factors justified accepting the gap without physical intervention. Where adjacent rail corridor fencing presented materially higher risk than the metro boundary, this was documented transparently even though it fell outside scope.
What We Delivered
A fencing review report covering all five corridor locations with location-specific recommendation sets and an SFAIRP assurance statement confirming the as-built configuration, with recommended supplementary treatments, could attain a suitable security outcome. Delivered from site inspection to final issue within five days.
Why It Matters
This project demonstrates targeted, proportionate security assessment of as-built conditions against specific compliance thresholds — a recurring need across infrastructure delivery. The approach applies to any rail, transport, or critical infrastructure project facing T&C or human factors compliance requirements for security fencing, barriers, or boundary treatments. Core42 is trusted by both asset owners and contractors on the same programme, providing independent assessment that withstands scrutiny from both sides.
