Dock building is just like other forms of construction, so the price of a project varies because it’s dependent on material selection, project area conditions, as well as construction access.
Generally, 1,000 sq. ft. is the maximum size for the dock.
A six-foot-wide walkway is allowed and isn’t counted in the 1,000 sq. ft. The dock may extend 150 feet out, or 1/3 of the distance across the channel, whichever is less. There are, of course, some exceptions on regulations, which you can read about here
We build in any season, but winter is usually the best time because water levels are down and this can sometimes make the construction process easier.
Each project is different, but, in general, a dock takes about 4-6 weeks to complete.
