Brett understands the challenges the building industry faces today, including having to deliver sustainable water management solutions to meet current regulations. As a leading innovator of permeable paving solutions, Brett designs cost-effective permeable pavement solutions for SuDS applications, and we’ve developed PermCalc to help Contractors and Specifiers save time when determining the total pavement construction cost. PermCalc is the only design software of its kind which can provide estimated construction costs based on either actual or default costs for each component or construction task.
