In 2017, a new 73 hectare community called Richlands started to be developed in the Town of Richmond Hill, one of Canada’s fastest-growing communities seeing not only a dynamic surge in
population but finance and industry as well.
A bridge and retaining walls were necessary to provide access to the new Richlands community. TACC Construction went with high quality and efficiency when they installed DECAST's precast bridge system (DE-SPAN) with precast footings and the Gravix system. 330 metres of Gravix retaining wall (369 units) was installed with sections that included the integrated traffic barrier option (103 units), this resulted in a maximum wall height of 6.1m. The development and house building phases could continue on through winter due to the rapid and efficient Gravix process.
