If you have a structure demolished make sure you make considerations about what kind of backfill you use. If you plan to dig another basement immediately after demolition you do not need to worry about backfill. In this case you would need to have construction plans first in order for us to get you a demolition permit (stay tuned for an upcoming blog post regarding permitting in Indianapolis and other areas). If you are never going to build back on area where structure once stood you can use a less expensive type of fill. However, if you do plan on building back in same are you need to use structured backfill and may want to consider having material tested by a 3rd party environmental company.
