While driving sheet piles, the contractor discovered a rock layer along the entire length of the seawall alignment. As a result, the vinyl sheet panels must be installed by pre-forming a hole by punching, drilling or excavating the hard strata/rock. This rock seawall installation method was included as an optional item in the construction contract at $275 per linear foot. At 1,051 linear feet the additional cost is $289,025.
