The priority on this scheme was maintaining access to the hospital’s 24 hour A&E department at all times, so our team constructed an access shaft away from the entrance and drove a traditional timber heading, causing no disruption to the traffic. After the 6 metre deep sewer was located in the carriageway, a 300mmØ foul drainage pipe along with saddle connection was made to the live main then backpacked.

Once this section of work was complete our crews continued on site installing a series of 225mmØ gravity sewers around the hospital perimeter using one of our Guided Auger Boring machines through chalk.
