Abstract A method for rehabilitating an existing bulkhead located between a body of water and land is disclosed. The method includes the steps of installing a plurality of tiebacks attached directly to the existing bulkhead, and a new bulkhead facing is connected to the existing bulkhead which has been supported by the tiebacks. An alternate method includes the steps of installing a plurality of substantially vertical piles at horizontally spaced locations in front of, i.e. on the water side of, the existing bulkhead; connecting the vertical piles to the existing bulkhead; installing tiebacks through the existing bulkhead and into the land behind the existing bulkheads; and connecting the tiebacks to the vertical piles. In situations where use of piles and tiebacks alone are not sufficient to rehabilitate the bulkhead, a new bulkhead facing is installed in front of the existing bulkhead and connected to and supported by the piles and tieback supported existing bulkhead.
A method of rehabilitating an existing bulkhead located between a body of water and land comprising the steps of: (a) reinforcing the existing bulkhead by: (i) installing a plurality of substantially vertical piles at horizontally spaced locations in front of the existing bulkhead; (ii) connecting said vertical piles to the existing bulkhead; (iii) installing tiebacks through the existing bulkhead and into the land behind the existing bulkhead; and (iv) connecting the tiebacks to the vertical piles; (b) installing a new bulkhead facing a predetermined distance in front of the existing bulkhead and supporting the new bulkhead in part with the reinforced existing bulkhead by: (i) inserting the bottom of said facing into the earthen bottom below the body of water; (ii) securing connecting members between said vertical piles and said new bulkhead facing; and (iii) backfilling the area between the existing bulkhead and said new bulkhead facing.
