SPECS worked with Jensen Precast and Magna Trucking to manufacture and deliver nearly 90 pieces of precast. The final tunnel posed a difficult install as it had an existing sewer line overtop. The sewer line had to be excavated and reinforced while the tunnels were set underneath. K&L made the process look easy by having the piece craned down onto the foundation and pushed slowly in place with equipment that they had on site.
