The Liberty Island was needed to provide future utility and cable needs. Horizontal
Directional Drilling was the preferred method of installation because it minimized any
disruption to the islands pristine environment and tourist activities and Bore-Gard’s
convenient 10 and 20 foot lengths were ideal for limited space. Three bores were needed
on the island, the first was 150 ft. under a bricked walkway to the corner of the gift shop,
the second was 190 ft near a row of oak trees, and the third was 240 ft. under a recessed
walkway near the base of the statue.

minimizing disruption to the

daily tourist activities made
Horizontal Directional
Drilling and Carlon Bore-
Gard the ideal solution.
A

ft barge pushed by a tugboat.

inch Bore-Gard ducts are being pulled
