In 2018 Universal Underground and their joint partner GT Civil were tasked with installing a 1.8 metre diameter concrete pipe under Cobham Drive, a four lane arterial highway into Hamilton city.
An upsized storm water pipe was needed to replace an existing undersized storm water pipe laid in the 1930s. The upgrade was part of the enabling works for a new interchange leading to a future bridge crossing the Waikato River to serve the rapidly expanding city.
Following the Pike River Mining Disaster the government included pipe jacking in the new mining regulations which meant open face jacking is no longer cost effective due to the cost of compliance. This forced Universal Underground to innovate to achieve pipe jacking without man entry.
