(i) Barrier Coating

Apply a continuous coat of bituminous paint or epoxy primer to the inside bottom and sides of shell, bulkheads, and bottom stiffeners only to the extent that concrete will come in contact with the aluminum surfaces. Paint may be applied by spray, brush, or roller and at a rate per manufacturer’s recommendation. Allow paint to dry and cure per manufacturer’s recommendation prior to placing concrete ballast.

(j) Concrete Ballast

Place concrete evenly in bottom of shell up to and level with tops of bottom stiffeners. Type “B” docks will not have concrete is spaces around the pile pocket as shown on the plans. Foam filler blocks shall be installed in place of the concrete in these areas only.

(k) Foam Floatation

Foam floatation blocks shall be placed using the sequence shown on the plans. The design allows for a 1∕8” space between the top of the foam and the underside of the bulkhead flanges and end stiffeners to allow for installation of the 1∕8” thick aluminum top covers.

(l) Screened Drainage Holes

Holes in the lower flange of the wale supports are critical for drainage. Each drain hole shall be covered with perforated aluminum sheet per specifications and details shown on the plans.

(m) Wales and grounding rails

Wales and grounding rails shall be ripped to finish widths and edges either radiused or left square depending on the application as shown on the plans. Wales shall be full length without splices. Leave 1/8” gap between all wales and wale blocks. Attach using blind rivet nuts with hex head bolts per manufacturers installation instructions and as detailed on the plans.

(n) Wale Blocks

Wale blocks are required at all wale ends with the exception of the end wale on the last dock. Wale blocks shall have a 45-degree chamfer as shown on the plans with the exception of the two off-shore blocks on the last dock. Wale blocks shall be attached with F-type zinc coated bolts: size, quantity and location as shown on the plans. Bolts shall be epoxy paint coated (black in color) prior to installation.

(o) Rubstrips

Install top of rubstrip along both sides of dock flush with top of composite wales using the supplier’s recommended “fold-over method” as shown on the plans. Attach with 2 rows of #8 stainless steel screws, 4-inches on center spacing. Also install a rubstrip across the offshore end of last dock. Ends of the rubstrip shall be finished by the manufacturer.

(p) Hinge Barrel Isolators

UHMW-PE bushings, sleeves and spacers shall be fabricated from solid material per details shown on the plans. Isolators protect against metal-to-metal contact and provide a wear surface between hinge barrels and hinge pins.

(q) Off-Shore End of Last Dock

The offshore end of the last dock requires modifications. Depending on the dock layout these modifications will apply to either a Type “A”, Type “B” or Type “C” dock (reference Dock Layout drawing). In place of the offshore end hinge barrel assembly, fabricate and install a wale support, wales, rubstrip, bullrail, sign post and corner wear blocks as shown on the plans. In addition, the last dock requires modified bullrails (both sides) for wheelchair access as shown on the plans.

(r) Shore End of First Dock

The shore end of the first dock will require modification only if a transition plate connection is required. Depending on the dock layout this modification will apply to either a Type “A”, Type “B” or Type “C” dock (reference Dock Layout drawing). In place of the standard hinge barrel assembly, fabricate and install a transition plate hinge barrel assembly, transition plate and hinge pin as shown on the plans. The transition plate width will be either 12 inches or 18 inches. Reference the plans for the correct transition plate width.

(s) Hinge Pins

All dock and transition plate hinge pins shall have a stop welded to one end with vertical sides as shown on the plans. The hole at the opposite end of the pin shall be drilled in the same plane as the vertical sides of the pin stop as shown on the plans. Provide bolt, nut, washers, and padlock for each hinge pin. The stainless-steel washer on the padlock end of the dock hinge pin is a custom size and will require milling to the dimensions shown on the plans. Alternatively, a 1¼” SAE washer may be used (1.375” i.d.) but may require reaming to fit.

(t) Boating Regulatory Signs

Attach signs to signpost as indicated on plans using stainless steel or aluminum rivets. Install signs level and plumb with sign surfaces free from distortion or other defects in appearance.

(u) Pile Hoop & Hinge Barrel Stiffeners (If required)

External pile hoops and dogleg dock hinge barrels require installation of structural stiffeners prior to installation of the wale supports. Each stiffener is a C5x9 aluminum structural channel welded to the dock shell at the locations shown on the drawing prior to installation of the wale support. The flanges of the channel will require trimming so that the outside face of the channel web is flush with the inside face of the wale support. Slots are cut in the wale support to provide slot welding of the wale support to the stiffener as shown on the plans.

(v) External Pile Hoops (If required)

05150.95

Weld external pile hoop mounting plate to the wale support at locations as shown on the plans.

Careful attention should be given to which side of the dock the hoop is to be installed and distance from the shore and offshore ends. Adjust lengths of wales and rubstrips as required.

(w) Abutment Hinge Barrel Assembly (If required)

The abutment hinge barrel assembly is mild steel construction, hot dip galvanized after fabrication with a metalized finish applied to all top surfaces. Assembly will be field installed by others.

(x) Dock Identification Plates

Each dock shall have a unique identification plate that will correspond to the naming convention shown on the plans or in the absence of a naming convention will be numbered sequentially starting with “1” as the first or shore end dock. Identification plates shall be consistently placed in the same location on each dock. Doing so will ensure that the docks are installed in the correct order and orientation. Minimum plate information is listed in 05150.85 (a); additional information on the identification plates is at the fabricator’s discretion.

05150.90 DELIVERY

The aluminum boarding docks shall be transported, lifted and stored in accordance with good industry practices, the handling instructions of the manufacturer and as specified herein. Stacking of one dock on another (3 docks total) is permitted with proper and adequate blocking and must not be supported by the bullrails (over a post) of the lower dock. For Type “A” docks, additional blocking at mid-span of the lower dock’s shell bottom must be provided.

Rubstrip material shall be protected from damage, compression or discoloration caused by tie-down straps used during transport. Adequate blocking shall be used to keep tie-down straps from contacting the rubstrips.

Manufacturer is responsible for delivery and offloading of docks at location designated by Owner.

05150.91 WARRANTY

The manufacturer of the aluminum boarding docks, and their related components shall provide the Owner with a written warranty that the aluminum boarding docks, and any related components shall be free of defects in materials and workmanship for a period of two (2) years, unless the Contract requires a more stringent or longer warranty.
