will try to be short...<br><br>our 2-story house has massive and unusual cracks, especially in the upstairs floor. We have had them since moving into the house when it was first built some ten years ago. the upstairs floor is a suspended concrete slab which is supported by two concrete supporting walls on each side of this floor.<br><br>We had a tradesman come to do some work recently. He was shocked at the state of the floor and urged us to look into it. So we had an independent engineer analyse the floor, he found there were profound problems with the structural integrity of the floor and supporting walls. This analysis was supported by a myriad of calculations and graphs showing where all the stresses were.<br><br>The architect (who was also the builder) has , since we moved in, consistently dismissed our concern abut these cracks, and since we told him about our report now refuses to engage with us. for years he kept telling us that the cracks are meant to relieve tension in the concrete. The builder's own engineer who originally signed off on the safety aspects of the house also stated this when he recently came to look for himself at the cracks. He was wiling to look at the issue however, unlike the builder who stormed out in a strop. <br><br>Our engineer advised that we should make sure the original engineer did his own calculations and analysis and warned we should not provide the recent anaylsis holus bolus to the builder's engineer: this would simply provide the original engineer fodder to refute our engineer's conclusions on a piecemeal basis, rather than making him work to demonstrate his own conclusions in a holisitc way. .<br><br>The original engineer keeps asking us for more and details of the report however. on the advice of our engineer, we have provided some of the calculations (from standard emgineering software for this sort of thing) but told him to contact our engineer directly for the details. <br><br>we are stuck on how to take this further. the original engineer seems nice, but seems lazy, and/or worried he would be liable.<br><br>have any other MNtters had to deal with structural issues like this before? how can we deal with the builder/architect and the original engineer to wear the liability? all the deadlines for the builder's insurance have expired. <br><br>going through the judicial/administrative complaints pathway is likely to take years and yearsand years to resolve, and could well provide an outcome we dont like.
