New and historic marble is pictured side by side on the southern side of the fully restored dock at Ca DZan mansion.
None of the material removed could fall into the ocean water below, therefore, containment was the first step taken in the demolition process.
Much of the rebar along the dock edge had completely deteriorated, requiring full-depth demolition of the concrete in these locations.
Where possible, plywood sheets were placed over the marble so they could be traversed without sustaining damage.
A crew of four men manned the hose line, vibrated the concrete, troweled the concrete, and protected the existing marble.
A total of 127 cu. ft. of 4000-psi concrete (4 3/4 cu. yds.) was placed on the day of the challenging pour.
