The data be collected prior and during soil compaction 2.The data be set out in a grid like pattern (Small house approx 20-30 PSP readings) 3. the results be sent to an engineer for certification 4. This critical data can now be used in analysis all along the build process 5. For example....Poor compaction and differential settlement means your slab will start cracking at slab loading (before they even start laying bricks) For further information and clarification you can leave a PM Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Can you give advice on how to get missing certificates needed for a form 21? Our bank requires us to provide one but we are missing 4 building certificates from our first… 3 71775 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 13053 |
