Carnarvon Highway

The FKG Group’s Civil team was engaged by the Department of Transport and Main Roads to widen and stabilise 25km of the Carnarvon Highway between St George and Surat, which the team was able to self-perform.

The main objective of the project was to provide a safer heavy vehicle route by widening the existing road from six metres to nine metres. To achieve this, the team completed road excavation, pavement widening, gravel overlay, recycling of existing pavement materials using insitu stabilisation with cementitious additives, bituminous sealing, and line marking.

In order to mitigate delays for motorists and to further ensure the safety of the local community, site works were performed in smaller work lots. The team meticulously planned traffic management to maximise the available work area and reduce the number of sections being concurrently worked on. Similarly, seal visits were programmed weekly to allow the newly completely works to be fully opened to two lanes as soon as possible.

With the project based approximately five hours from Toowoomba, the team was required to implement forecast order tracking to navigate logistics for the material supply chain and ensure subcontractors were booked well in advance. This initiative ensured the construction program remained on track and was successfully completed ahead of time.

Understanding the potential impacts on locals, the team frequently liaised with key stakeholders and engaged with the community to notify them of any closures or change in works, which led to nil complaints received.
