Drizzle again today, Tam and Cyril drove the next 2 greenheart piles at the top of the access walkway. I started to discuss the length of the pontoon piles with John Davis as I believe that they are too long to be driven so the splice will below mud level. Agree to cut a metre off one and see how it goes - seems quite high risk, but we've driven a lot of piles now and none have gone more than 5metres into the river bed!
