Build your frame at the edge of the water and use galvanized joist hangers with the teco nails on every joist. Then double up the rim joist that abuts the telephone poles.
This will keep the fame light enough to move into place.
Snap a line across the telephone poles and drill out the poles so you can run a galvanized bolt through the pole and through the outer doubled rim joist. Then just finish off the decking with the frame bolted into place.
In order to easily slide the deck frame into place nail a 2x6 to each pole perpendicular to the shore line. Set the 2x6 below your finished deck height by adding up the thickness of the decking plus the thickness of the joists. This will safely hold everything up till you can bolt the frame into place. Don't drill your holes into the outer rim joist till the frame is slid into place.
Hope it makes sence.
