Sterling's Approach

Structural Design for Rail, Road, and Industrial Infrastructure

Sterling delivers structural design services for bridges, buildings, platforms, and industrial infrastructure across rail, road, and commercial sectors. Our design capability spans new construction, major renewals, and capacity enhancement projects, with particular expertise in rail infrastructure where operational constraints, safety interfaces, and possessions windows dictate design and construction methodologies.

Sterling has delivered structural designs including the Light River Bridge replacement for ARTC (3-span steel trough deck replacing historic timber structure), Pier 1 replacement design, Swan Street mezzanine structural modifications for Metro Trains Melbourne, and platform extension designs for accessibility compliance. These projects demonstrate our capability to design practical, buildable solutions within operational rail constraints and tight delivery timeframes.

Our design approach prioritizes constructability, accounting for possession durations, temporary works requirements, staged construction sequencing, and operational safety interfaces from the earliest design phases. This ensures proposed designs are actually deliverable within client operational and budgetary constraints, avoiding over-engineered solutions that are theoretically optimal but logistically impractical.

Deliverables & Value

Design Documentation & Buildable Solutions

Construction-ready designs optimised for operational constraints

Deliverables

→
Construction Documentation
Detailed design drawings, specifications, and construction methodologies compliant with Australian Standards (AS 5100, AS 3600, AS 4100, AS 1170) and tailored to client operational constraints including live rail possessions, traffic management, and safety interfaces.
→
Structural Calculations and Models
Comprehensive structural analysis documenting load paths, member sising, connection design, and compliance with code requirements, providing transparent technical justification for design decisions and enabling efficient approvals processes.
→
Constructability Reviews
Value engineering assessments identifying opportunities to optimise construction sequencing, reduce temporary works complexity, minimise possession durations, and improve cost-effectiveness without compromising structural performance or safety.

Value Delivered

→
Proven Rail Infrastructure Design Experience
Sterling has delivered structural designs for ARTC (Light River Bridge replacement, 3-span steel trough deck), Metro Trains Melbourne (Swan Street mezzanine modifications, platform extensions), and V/Line (structure renewals under SDIP). This experience demonstrates capability to design within operational rail constraints and tight delivery timeframes.
→
Design Optimised for Constructability
Sterling's designs account for possession durations, temporary works requirements, staged construction sequencing, and operational safety interfaces from concept stage. This approach ensures proposed solutions are practical, cost-effective, and deliverable within client operational and budgetary constraints.
