ABSTRACT:
The specification discloses a precast concrete dock and a method and apparatus for installing same. The dock includes a precast concrete platform supported by piling means at one end and including at least one generally U-shaped bumper member with legs projecting laterally beyond the side edges of the platform and being made of a material more resilient and less abrasive than concrete whereby there is less damage to a boat bumping into the bumper member legs than would be the case if a boat bumped into the precast concrete platform. To install the dock, an elongated jig having legs at one end is located out over the water and slidable guide means on the apparatus are located at a point where it is desired to locate pilings. Pilings are lifted into position within the piling guide means and jetted downwardly into the surface below the water by means of an internal passageway. After they have had an opportunity to set, the jig is removed and the precast concrete platform is lifted out over the water and supported at one end by the installed piling means.
