First, the document is not enough detail because I was forced several times to dismantle to go up. Then the two brackets (3 points each) that maintain the block with the work plan was off. To strengthen the whole I added 2 screws on each side. Moreover, I had to pick up the sink that was dissociate into 2 pieces and I added a square to reinforce the underside of the sink. I also expanded pre-holes 3 hooks above the plate if not impossible to screw the elements without damaging them.
