Constructability Rail, Road, Bridge, and Level Crossing: Our engagement consisted of various practical, strategic and technical services including constructability, maintainability, deliverability, risk assessments, and cost estimation.

Stakeholder Engagement: Agonis worked collaboratively with key stakeholders in PTA, WA Government, Arc Infrastructure and CBH to prepare the report that benefited all stakeholders by proposing a track structure that ensured lower maintenance infrastructure costs, higher axle loads, and higher train speeds. The report established that higher grain tonnages could be carried on rail hence reducing truck movements and the impact on roads and community safety.
