Actually, the block was poured on Saturday, I went with 25Mpa in the end and a light reo box to help avoid cracking. I have decided to use four bolts as the pier base I have is square and that allows me to spread the bolts as far apart as possible. This will be an AP pier so precise level won't matter that much.

I am waiting another two weeks for close to final cure then drilling holes to chemset the bolts in. I could probably do them this weekend given it is not really stressed much, the nuts more or less only need to be snugged up rather than torqued down to hold the Sydney Harbour bridge, but the last thing I want to do after digging that hole by hand is pull chunks out of it by being impatient!
