This design and construct contract was for the replacement of four timber bridges with pre-cast concrete box culverts and the replacement of two flood-way openings. The waterway was to be maintained or increased on all sites.
The location of the works was close to the township of Dalby in Queensland. It has been one of many projects that VEC has successfully completed for Queensland Rail.
With the location of the project work sites being extremely remote, access to the majority of the sites was particularly challenging. Our team of experts have become accustomed to finding innovative solutions in accessing such difficult work-sites whilst ensuring disturbance to the local environment is minimised.
Furthermore, poor ground conditions posed challenges throughout the construction of the structures.
With professional environmental management and controls, our team were able to overcome these challenges. The Project Management team delivered meticulous planning putting lessons learnt from previous projects into action.
Temporary gravel access tracks were constructed to allow the team and all plant and equipment to safely reach the construction sites.
With the sub-grade conditions being far from desirable, our team devised a methodology that entailed a 500mm thick stabilised sand base over the poor sub-grade. This meant that the impact of the substandard sub-grade could be mitigated and the project could be completed successfully.
The project was completed with zero safety or environmental incidents. The experienced project management team drew on previous experience to ensure the project program accommodated all of the site conditions and project requirements.
