Avoid stormwater detention tanks

Smart design solutions that eliminate the need for space-hogging tanks.

More space for your vision by remodelling flood flows

Innovative flood conveyance solutions that unlock additional floor space and development potential.

Lift site yield: reduced stormwater basins

Innovative drainage modelling and council negotiations that generate more development potential and lower build costs.

Avoid stormwater detention tanks

Smart design solutions that eliminate the need for space-hogging tanks.

Lift site yield and reduce build cost: reduce stormwater basin

Streamlined flood studies and council negotiations that fast-track your development approval.

Lift your site yield by piping flood flows

Innovative flood conveyance solutions that unlock additional floor space and development potential.

Avoid a split floor level because of flood levels

Engineering solutions that maintain consistent floor levels across your entire building footprint.

Ditch gutters and downpipes altogether

Innovative roof drainage designs that simplify construction and reduce ongoing maintenance.

Make rainwater drainage a feature

Alternative drainage strategies that create beautiful surface water features, instead of hiding water in pits and pipes.

Our Services

Stormwater

Stormwater drainage design for planning approval and construction. From single homes to hundreds of lots. Water quality and water sensitive urban design (WSUD). On site detention tanks, basins, modelling.

Water and Sewer

Gravity and pumped sewer network design for large scale development and single homes. Network modelling and 3D design. On site sewage treatment systems and rainwater reuse.

Civil

Site grading and earthworks optimisation including 3D modelling. Large scale subdivisons, complex sites, quarries, mines, industrial and commercial properties. Integration with stormwater, flooding, water, sewer and other services.

Traffic and Access

Trip generation and traffic reporting. Geometric design for small and large scale properties. Heavy and light vehicles, with swept paths and scraping checks. Horizontal and vertical geometry.

Flooding

Large scale catchment modelling. Property-scale flood and overland flow modelling. Optimisation to support development and design outcomes. Modelling to allow SEPP and avoid council approval pathways.

Roads and Pavement

Public and private road and network design, including car parking and industrial hardstand. Intersection design for local government, TfNSW and QDTMR. Reinforced concrete pavement, flexible pavement, asphalt, and bitumen seal.
