Proform Civil was contracted to undertake the design and drafting to enable construction of an upgraded intersection at Hillsden and Darlington Roads.
The existing intersection was on an unconventional alignment which was "forked" with the termination of Hillsden Road splitting into two roads surrounding a three way power pole at Darlington Road. The road pavement was rough and the seal had worn away in areas.
The design would upgrade the intersection to a standard "T" alignment and provide footpath and drainage infrastructure. The power pole was relocated and asphalt thick lift methodology was used to rebuild the pavement.
One of the challenges of the project was to overcome an existing underground fibre optic Telstra asset which crossed Hillsden Road close to the intersection with less than 50mm of cover. After numerous site visits and conversations with the asset owner a suitable solution to lower the fibre was deemed too expensive. Proform Civil developed a solution to alter the geometric alignment of the roads which would provide suitable cover over the asset without affecting adjacent verges or aesthetics too radically.
Proform Civil was a valuable asset to its client throughout the construction of this project. Been on call for the majority of this phase and negotiating directly with the surveyor's and the construction team to achieve a smooth construction process. In discussions with the surveyors Proform Civil insisted on outputting what is known as a ".ttm" file which would allow the surveyor to easily upload the design surface into their Trimble surveying equipment and provide instant surface levels at any location along the design for the surveyor to setout. This setout technique was highly beneficial throughout the process of installing the asphalt thick lift pavement.
A signage and pavement marking plan was developed for the scope of work and approved by Main Roads for installation. The project has been constructed and has eliminated driver confusion at the intersection with improved amenities.
