Browse Forums General Discussion 1 Jun 01, 2013 11:01 pm Hi all, not sure if anyone have this issue before... But I've soil report from my developer and builder and they've come back quite differently in a 1.5 years period... The report from my developer was M site classification with characteristic surface movement of 20-40mm Then a recent report by the builder shows P site classification with characteristic surface movement of 40-60mm... My question is 1. Is this possible? 2. If it is... Is it showing something bad about the land? Like very bad corrosion or something?? 3. If its not... Should I bring this up with the builder? Thanks for any help!! Re: Site classification help 2Jun 01, 2013 11:05 pm Does the report show the amount of fill on your land? Maybe the developer added a bit of fill on to you block, which is why it is classified P (problematic) Never argue with an idiot. They will only bring you down to their level and beat you with experience.

Is mostly interested in selling blocks Since the tests were taken has had sewers and drains constructed on the site. Probably done some spreading of fill from roadworks construction and site leveling The builder Has had 3 tests done on your block. Is mainly interested in avoiding claims for foundation movement causing structural cracks The Harder You Try - the Luckier You Get !

Re: Site classification help 7Jun 13, 2013 8:03 pm The difference between M & P site classification could be tens of thousands of dollars in extra site and engineering costs. I would be doing another independent soil test (as second opinion) just to make sure the builder is not over engineering.

This then becomes a contractual matter where the builder (their engineer) must certify that the solution is effective for the conditions. I don't know your circumstances. Are you an owner builder or have you got a fixed price contract? Or are you selling the land? This may have a bearing on how you handle this matter but generally shift the risk if you can. because its not being managed properly. Also "properly" is too broad and too subjective a term to be able to pinpoint a single event as not being managed properly.… 1 2729 I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills. 2 8262 |
