stormwater and flooding

FJA undertake all hydralic and hydrology design and assessments. We can design pit and pipe stormwater networks or undertake full flood catchment analysis.

water and sewer

FJA have been involved with relocation of trunk water and sewer assets with Sydney Water over the last ten years. We have accreddited designers for all sizes of water and sewer mains.


We provide Level 3 ASP designs for overhead, underground, low voltage, high voltage and substation projects. We coordinate with our civil team to ensure that our designs work and integrate seamlessly with all design elements.


As a multi disciplinary team FJA derive a lot of value through building a coordinated model for all of our team to utilise.

We use Navisworks, Civil3D, 12d and Revit to combine complex data sets into a usable model that the whole project team can view online.
