I initially just put padlocks on the attic access hatches, however I needed to get final building inspections and they required a firewall not only in the attic, but below the house to the foundation (my duplex is pier and beam, elevated 2 feet above grade).

All of the waste was piling up underneath the pier and beam.

The brick columns appear to support a largish steel beam, so maybe this is 1920's vintage.

Create such a laser-like focus on your goal that it ensures you will get there reasonably soon.

However, we definitely like a complete set of plans so we know what we're dealing with in order to provide an accurate bid.Digging out a foundation for beams and footing differ greatly across soil types and foundation types, also being the most expensive part of the build, must be as accurate as possible to bid you a good price without change orders, or going back on the original price.

The Property: 1968 pier and beam house, 1344 sq ft.

See if weeds have grown up or trash is near the Beam or reflector.

Is this pier and beam or slab foundation?

The only estimate I've received on those was from a company that said I needed to spend about $12,000 to have steal beams put in to shore up the wall...but his company didn't do that (which is why I considered the estimate to be invalid).  

However, the foundation is not the standard crawlspace of stick built homes, and I believe it is two pieces each on an I beam.
