After hydro excavation exposed the existing utility connections, the team surveyed entry and exit elevation of the pipe to determine the correct angle for casing installation. The casing was drilled from street level, down to the concrete abutment. Once the casing was seated into the concrete, the team was able to core drill the remaining distance with standard tooling. The borehole exited the abutment on the targeted location at the receiving pit below, which allowed for the customer to install 8” diameter ductile iron pipe. Upon successful pressure testing of the pipe, Brayman grouted it into place. Team Brayman appreciated the opportunity to provide the customer with a safety-minded, cost and time saving solution that allowed the connection to the street level utilities to be completed in just a few days, instead of weeks or months and reducing the traffic impacts on a busy downtown street.
