Due to the Campus’s location being so close to the city’s main road network, there was a requirement for ample parking space.
When the originally specified stormwater management system for the project was deemed over budget, Polypipe Civils & Green Urbanisation [Polypipe CGU] worked with the appointed principal contractor, P.P. O’Connor, to supply a system that would deliver over £200,000 in cost savings.
Alongside supply and install partner Hydro WMS, Polypipe CGU was able to offer a geocellular stormwater management with treatment solution in the form of Polystorm and Permavoid. This included 2,700 Polystorm-R cells, 600 Permavoid Medium Duty with Biomat cells and more than 600m of Permachannel.
“Polystorm-R is designed for use in trafficked areas, with a compressive strength of 61tonnes/m². Its modular structure made it ideal for use within the site’s restricted areas, where the car park was being installed around existing buildings,” said Rosie Cheetham, Marketing Manager at Polypipe CGU, “By employing the Permavoid and Polystorm systems in conjunction with each other, the design was re-worked while still allowing the controlled water treatment and surface water run-off across the site as per the initial design."
Chris Reilly, Commercial Director at P.P. O’Connor, said: “We were able to work with Polypipe to supply a cost-effective, reliable, and easy to install system that helped the client significantly reduce costs without compromising the quality of the final car park. Polystorm and Permavoid provided us with an ideal solution for a large car park area, and with further expansion in the pipeline at this site, we will be able to put a similar system in place.”
