This time lapse shows the docks being installed on the James River in Richmond Va.

The new community on the James River has leased just five of the 40 boat slips it began putting into the water in February 2009 to create a marina that will serve condominium dwellers and other private boaters.

Crews install marina anchor piles in preparation for dock delivery. Cranes drive 35-foot steel pipe piles into the riverbank. An on-barge excavator removes debris and old pilings before placement of floating docks.
