Civil Maintenance & Construction

With nearly 30 years of proven delivery and 25,000+ projects completed right across all Australian states and territories, Sterling's Civil Maintenance & Construction division provides specialist infrastructure works within live transport networks. Our capability encompasses structure repairs, track formation works, roadway and pavement works, drainage installations, utility crossings, and building modifications.

Sterling's integrated construction model eliminates handover delays between inspection, design, and construction phases. Our structural engineers who identify defects during condition assessments are the same team designing remediation solutions and supervising construction delivery, ensuring technical continuity, rapid mobilization from defect identification to remediation, and optimized constructability informed by hands-on maintenance experience. This integration has delivered measurable efficiency gains across major rail infrastructure programs, reducing project timelines and improving delivery certainty.

From reactive maintenance and emergency repairs through to planned infrastructure renewals and major construction projects, Sterling provides comprehensive civil construction services for transport infrastructure operators. Our capabilities extend across concrete and steel structure repairs, track formation stabilization, drainage and erosion control, utility protection and crossing works, platform modifications, and station facilities construction, enabling transport operators to maintain infrastructure reliability, meet regulatory compliance obligations, and deliver capital works programs within operational constraints.
