Proform Civil was contracted to provide civil engineering and consulting for the design and documentation of multiple proposed internal car parks at Helena College Senior High School.

The scope of work included formalising existing car parking along with the design of drainage retention systems to match pre development run off in line with water sensitive urban design. A kiss and drive student drop off road was designed and matched into the internal structure to improve congested traffic flows.

A total of 156 parking bays were included in the design along with accessible bays. The vertical design was challenged by steep sloping topography. To reduce construction costs on boxing out material to spoil the design utilised maximum cross falls suitable for car parking to closely match existing surfaces with minimal earth work batter slopes.

The internal layout had limited room to accommodate the space necessary for the pavement widths. Conveniently surround by council reserves Proform Civil designed the car park with the kerb close to the boundary allowing batter slopes to be constructed in adjacent shire reserves after negotiation with the reserve owners.

The existing car park to be formalised was undesirably high and sloped towards adjacent School buildings. The vertical design was optimised to cater for large storm events and regrade the design car park away from nearby buildings.

Due to a number of previous projects on the site, Proform Civil was required to amalgamate multiple surveys into a known datum and perform onsite checks using level surveying equipment to enable the commencement of the design. The ability to undertake this task was at a cost saving to the client.
