SUS Projects
National Harbor Marina
Specialty Underwater Services (SUS) pile driving crews were called out on multiple occasions from our Baltimore waterfront facility to provide some quick needed work for the boating season. On one trip timber piles were removed and disposed of properly and replaced new piles. In addition, damaged facial timbers and hardware were replaced and new hardware was installed at the floating dock connection. Subsequent trips included the removal and disposal and replacement of timber piles.
Ft. Washington Marina Demolition
This project consisted of mobilizing our tug and crane barge from our Baltimore facility to support the removal of over 1,500 LF of timber piles and 1,100 LF of steel pipe piles. Our team also dismantled and disposed of 10,000 SF of aging floating dock structures and terminated the utilities at the bulkhead.
Robinson Landing
Specialty Underwater Services was contracted to provide Pier Rehabilitation. The work consisted of the removal of the existing Timber Structures, Dolphins and Piles along with the demolition and removal of the existing boathouse, light poles and pier handrails. Once the demolition work was completed concrete repairs were made to the under-deck of pier, the pier deck itself and the concrete curbs. New Concrete curb was installed along with structural steel repairs. A new “D” fender was installed around the pier and the sheet pile wall was extended for the bulkhead and a new concrete cap was poured.
