We moved into our home late last year. We are getting ready to do some remodeling and have been working with a local contractor. The plan is to add a bedroom onto the rear and reconfigure part of the existing space to add an additional bathroom.
The contractor plans to cut a hole in the slab so his plumber can tie into the existing drains for the new bath. When we purchased, we had a home inspection. I looked at the report today to refresh my memory. The inspector said the house is built on a post-tension slab foundation. He also mentions in the report that modifications to this type of foundation can be extremely difficult and should be done only under the supervision of a structural engineer.
When I asked the contractor about this issue, he said not to worry - they cut slabs all the time for this type of addition.
Is this something we should be worried about? If so, who should we talk to for more info?
