St. Mary’s College Rowing Center Gangway and Floating Dock
As part of updating their waterfront activity center, the school contracted with Dissen & Juhn Corporation to install a new bulkhead, raised piers, boat ramp, aluminum gangway, and floating boat dock. Dissen & Juhn, in turn, contracted with BoardSafe to design, construct, and deliver the aluminum gangway and floating boat dock.
The main challenge in constructing the floating boat dock was the 8-inch free board (distance between the top of the dock and water) requirement. The 8-inch free board is necessary so that the top of the racing skull is at the same elevation as the top of the dock. This allows for easy boarding and exiting of the vessel by the college's sculling crew.
A related challenge focused on the floating dock frame. A normal floating boat dock consists of a frame that sits on top of flotation, but the St. Mary’s dock would have to be designed in such a way that the flotation was incorporated into the frame.
BoardSafe, as part of the design phase, calculated the weight of the completed frame (framing materials and decking) and determined the amount of flotation required to give the completed dock the required free board. The number of floats under the dock directly affects the free board; the greater the number of floats, the higher the free board, and the greater per square foot support. In turn, the fewer the number of floats under the dock, the lower the free board height and support per square foot. The calculations needed to substantiate the number of floats needed ultimately provided the desired free board.
The aluminum gangway was designed in accordance with current ADA specifications and measures 5-feet wide by 30-feet long. After the design was completed and approved, fabrication began at our manufacturing facility in Pennsylvania.
The custom floating boat dock frame was 10 feet by 50 feet and fabricated using our proprietary mainframe and aluminum tubing. Once the frame was completed, the specified floats were installed and the pressure-treated decking put in place as the design required.
Additional flotation was also added in the area where the gangway would rest on the floating boat dock to provide additional support for the point load created. Once completed the floating boat dock and aluminum gangway were delivered to the St. Mary’s campus and installed by Dissen & Juhn Corporation.
Both St. Mary’s and Dissen & Juhn were highly-satisfied with the custom floating dock and gangway solution BoardSafe designed and manufactured for this project.
Conshohocken, PA, Rowing Center Features BoardSafe Aluminum Docks and Products
One of the centers of the rowing community in the United States is Boathouse Row in Philadelphia. Rowers from the boathouses compete at every level, including local clubs, high schools, colleges, summer racing programs, and international-level athletics. The newest and finest facility in the area is not at Boathouse Row, but a few miles upstream.
Conshohocken is located just north of Philadelphia, PA, on the Schuylkill River. The Conshohocken Rowing Center was unveiled in October 2014. The state-of-the-art facility is a 6-bay building that houses The Haverford School , Malvern Preparatory School, and the Borough of Conshohocken. The operation of the building is a public and private relationship that encourages local and youth rowing. Because rowing is serious business in Philadelphia, the members of Conshohocken Rowing Center wanted the best dock builder they could find.
They did not have to look hard to find Pennsylvania-based BoardSafe, a trusted and expert dock builder with projects up and down the east coast. BoardSafe custom-designed, manufactured, and installed the docks and the observation deck.
The observation deck is an aluminum frame dock with Nylodeck synthetic wood, featuring the TimberStrong fastening system. The large observation deck was designed to provide great views and accommodate several hundred fans. The deck runs along the rear of the rowing center building and was engineered to cantilever over the riverbank. It measures 24-feet by 122-feet and features:
- a concrete foundation system (engineered by Innovative Marine Solutions , a sister company of BoardSafe - PE stamped drawings).
- a galvanizedstructural steel support frame (also engineered by Innovative Marine Solutions - PE stamped drawings).
- fifteen (15) 8-foot-by-24-foot aluminum joist system panels.
- a 42-inch high ultra aluminum rail - powder-coated black.
- docks designed to provide a 6-inch freeboard under no live load. The docks are BoardSafe Commercial Aluminum, featuring NyloDeck (Desert Spice color) attached to the frame with the TimberStrong fastening system.
- steel frame components, aluminum panels, decking, and railings, installed by Innovative Marine Solutions employees.
As impressive as the observation deck is, the floating docks and structure are unparalleled (scroll down to watch aerial videography of the project).
The floating docks project includes:
- one main aluminum dock measuring 10-feet wide by 360-feet long.
- six finger piers and three support arms.
- a 42-inch high ultra aluminum rail - powder-coated black
- The docks were designed to provide a 6-inch freeboard under no live load. The docks are BoardSafe Commercial Aluminum, featuring NyloDeck (Desert Spice color) attached to the frame with the TimberStrong fastening system.
All of the steel frame components, aluminum panels, decking, and railings, were installed by BoardSafe.
