The first phase of the Sheffield Hallam University green campus plan is nearing completion and includes three new buildings around a public university green.
The ABG blueroof system was specified to provide SuDS stormwater attenuation atop of the three new buildings.
The outflow of rainfall from the rainwater outlets during a calculated storm event is restricted by the blue roof system, so that instead of large volumes of water deluging into the drainage network during a short period of time, the stormwater outflow is delayed over a number of hours.
In total, ABG Installs completed the installation of 5,000m2 of the ABG blueroof attenuation system for the three new campus buildings (Block A, Block BC and Block D), together with a varied range of both hard and soft landscape finishes.
This includes 1,250m2 of paving and surrounding ballasted areas and over 700m2 of planting, made up of a combination of wildflower and sedum matting, together with a range of ornamental shrubs. Johnsons Nurseries supplied over 4,500 plants in total to enhance the biodiversity and aesthetic aspects of the development, including planting for the bespoke rooftop planter areas.
