Hi There! We are building a pharmaceutical plant near the seaside in Europe....the site is made ground over estuarine and marine alluvial, over weak rocks, clays and sands of the mercia mudstone group with alluvial sands and mercia mudstone group. Base on the SI report we suggested to our client the use of vibro concrete columns for the process area which will be heavily loaded with super heavy process equipment but was rejected by the client coz they said that they worry about the cost and the settlement of the clay in long run...was wondering do you guys have any suggestion? Me and my mates here are struggling to come up with a good foundation design for our boss
