Finished welds are to present a neat workmanlike appearance.

The preferred filler wire for all aluminum welding shall be ER5183. However, ER5356 is an acceptable alternative.

Weld spatter and slag shall be removed.

Weld continuous all connections unless otherwise shown in the plans.

Any welding, done after the installation of the foam flotation blocks, is to be performed in a manner which does not damage or cause burning of the foam. The Manufacturer is fully responsible for maintaining the integrity of the foam throughout the fabrication process.

(d) Decking All decking shall be non-skid and installed flat and true without intentional changes in slope or tripping hazards and compliant with accessibility standards.

All decking shall be installed with Fibergrate Spring Clips, part number 734282, or approved equal.

Location and quantity of clips are shown on drawing sheet 18. Clips shall be fastened with #12 x 1- ½” 316 stainless steel bi-metal self-drilling screws with 3⁄8” hex head.

Pultruded fiberglass grate shall be installed in as large of panels as practical with the bearing bars oriented perpendicular to the span direction of the dock. The affected ends of any field or shop cutting or drilling of fiberglass grate bars shall be sealed with catalyzed resin sealant as recommended by the grating manufacture or polyurethane. Panel layout may be adjusted as needed to minimize narrow strips of decking from cutouts around pile pockets.

(e) Fasteners All fasteners shall be the size and type shown in the plans.

Washers are required under the heads and nuts of all fasteners unless noted otherwise in the plans.

All fasteners shall be appropriately fully tightened in accordance with applicable industry standards and practices.

Any fastener in a walking surface shall be flush with, or recessed below, the surface or concealed.

All threads to be liberally coated with a marine grade anti-seize compound prior to installing nuts.

(f) 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.

(g) 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.

(h) 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.

(i) 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.

(j) 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.

(k) Wale Blocks

05150.91

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.

(l) 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 off-shore end of last dock.

Ends of the rubstrip shall be finished by the manufacturer.

(m) 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.

(n) Off-Shore End of Last Dock The off-shore end of the last dock (2) requires modifications. A temporary end cap is detailed in the drawings to be installed when fewer than four (4) docks will be utilized. The end cap provides the bullrail, rubstrip, and sign post holder built into the last dock. In place of the off-shore 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.

(o) Shore End of First Dock The shore end of the first dock will require modification to accept the gangplank as shown in the drawings.

(p) 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.

(q) Boating Regulatory Signs Attach signs to sign post 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.

(r) 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 3.1 A9; additional information on the identification plates is at the fabricator’s discretion.
