In 1993, the existing Southpine and Tributary Creek bridges in Strathpine were strengthened to allow for additional railway loading along with the installation of additional concrete piers designed for future span replacements.
Over 20 years on, the main objective of this project was to remove the existing spans, demolish the existing concrete and cast iron piers, and install new slab spans. A secondary benefit of the project was to undertake track alignment modifications which allows increased line speeds within the section.
The length of the works was approximately 2x700m tracks along two bridges and an embankment,
and was undertaken within a 168 hour rail closedown.
Project scope involved:
- removal of 1400m of existing track structure including guard rails
- installation of bottom ballast along the newly installed concrete spans
- installation sleepers and rail along the length of the works
- top ballasting operations using ballasting works train
- undertake resurfacing operations
This project highlights Martinus’ ability to perform significant work scopes in short timeframes, with the need for meticulous planning paramount for the success of these types of projects. Our team has extensive experience in the delivery of possession critical works and this ensures all stakeholders benefit from these projects with minimal risk.
