Abstract: A dock or pier assembly is constructed of a series of substantially identical dock modules. The dock modules are preferably rectangular in shape, and a post and bracket support arrangement is provided at each corner of each dock module for supporting the dock modules above a body of water. Each dock module includes a frame assembly, constructed of a series of metal frame members welded together to define a rigid frame. A series of deck members are mounted to the frame, and may be in the form of extruded plastic deck members. Each side frame member includes an upper flange to which a connector strip is secured, and the connector strip defines engagement structure for mounting the deck members to the side frame members. Each frame member of the frame assembly further includes a vertical web and a lower flange. A bumper or cover member is secured to the vertical web of each frame member, for providing a finished appearance and for protecting the web and lower flange when in use.
