Howard's letter to ASCE's Civil Engineering magazine's editors was published in this month's issue. In particular, Howard points out that floating raft foundations, while a good solution for the project under discussion (from an article published in a previous issue), are by no means "innovative", as claimed in the previous issue. To wit, Howard provides quite a good bibliography of texts that discuss this type of foundation. Many of the references will no doubt be familiar to frequent readers of BigH's posts on EngTips.
