All docks and breakwaters shall be constructed with environmentally safe materials as defined below.

Steel or Aluminum
  • All steel shall be powder coated, galvanized, or painted with a primer and painted with a minimum thickness of 3.5 mils. All dock primary substructure metal and angle iron shall be a minimum of 11/2 x 11/2 inches x 3/16 inch or 2 x 2 inches x 1/8 inch. Round rod shall be a minimum 1/2 inch. Smaller thickness, nonessential frame metal and angle iron may be used when approved by a Registered Professional Engineer and shall be no less than 1 inch x 1 inch x 1/8 inch.
  • All holes, cuts, or wells on steel members shall be made prior to hot dip galvanizing or painting.
  • After assembly of new docks, repairs or modifications, etc., all welds must be touched up in the field with the appropriate coating (i.e., cold galvanizing or paint).
  • Connectors shall be plated steel or stainless steel.
  • All structural steel welding shall conform to American Welding Society Standard (AWS) D1.1, latest edition. All structural steel welding electrodes shall conform to AWS A5.1 or A5.5 E-70XX. All exposed welded connections shall be free of excessive burs and sharp edges.

Cold Formed Steel
  • Cee shapes, zee shapes, and other cold rolled shapes shall be designed in accordance with the Light Gauge Structural Steel Design Handbook.
  • Cold-formed steel joists, purlins, beams, etc., shall be galvanized with a G-60 coating meeting ASTM standards or equivalent.
  • Metal panels shall be plated, galvanized, powder coated, or painted to provide adequate corrosion resistance.
  • Cold-formed structural steel and roof panels shall have gauge and strength required to resist dead loads, live loads, and construction loads.
  • Roof systems shall be designed to support the appropriate loads.
  • Roof panel design and structural load carrying capacity shall be as recommended by the panel manufacturer.

  • Wood frame substructures are prohibited unless specifically approved by Ameren MissouriĀ and engineered to meet the wave loading of the site.
  • Wood used for deck boards and banding trim must be pressure treated and be consistent with the latest Environmental Protection Agency (EPA) regulations.

Structural framing members shall provide corrosion resistance and strength as required by a Registered Professional Engineer.

  • Cables or chains shall be designed with a minimum working load safety factor of 3.0 for cables and 2.0 for chains.
  • All cables or chains shall be galvanized or stainless steel.
  • Anchor design shall be completed with sound engineering practice and the soil properties assumed (if soil testing was not completed) shall be shown on the plan documents. Submerged anchors must be positioned to accommodate low water levels, as not to present a navigational hazard.
