The number of laser treatments a tattoo requires depends on the depth of the tattoo, the types and colors of ink used, the color of skin to be treated, and the types of lasers used to eradicate it.
The Cost to Build a Boat Dock. The costs associated with dock construction are extremely variable. Prefabricated or assembled docks can be as cheap as $1,000 while high-quality permanent docks can cost between $50,000 and $75,000, depending on the difficulty of installation, water depth, climate, and other factors.
1 Piling docks, perhaps the most popular type of permanent dock, usually cost about $20 to $40 per square foot. That includes installation but not fancy features such as gazebos, rails or lifts. Those features can raise the price to $60 per square foot.  Adding a boat lift usually costs an extra $5,000 to $7,000.
