Connecticut Administrative Code
Title 13b - Transportation
17 - Encroachment Permit Regulations
Section 13b-17-33 - Jacking, boring or tunnelling

Pipes and conduits crossing limited access highways, highways with heavy traffic, in areas of deep excavations or other special circumstances, shall be installed by jacking, boring or tunnelling, except where proven to the satisfaction of the State, by the permittee, to be technically impractical. Installations on all other highways, in areas where jacking and boring are technically impractical, or installations parallel to the traffic, may be placed by the open-cut method if approved by the District Maintenance Manager. No jetting or other use of water will be allowed in connection with jacking or boring.

The permittee shall be responsible for careful investigation of the permit area to determine the location of all existing utility, municipal, private or State-owned pipe or conduit lines and service connections. When required, he/she shall submit a plan and profile showing all such lines and indicating, thereon, the location of the proposed installation to be made by them.

When jacking or boring installations are under consideration, the permit applicant shall submit detailed plans showing the method of operation, including the jacking and receiving pits, cradles and thrust blocks. If the plan is approved, the permit will be issued on this basis. The permittee shall submit soil exploration data when required to do so by the District Maintenance Manager.
