Reference material anyone?
I'm looking for a comprehensive listing of the unit weights (pounds by area or volume) for various building materials for the purpose of estimating demolition disposal quantities. I've been surprised by how hard it is to find unit weights for items like plaster on lathe, sheathing, brick and block work, flooring materials, siding, etc. Anyone know of a good source for such information?

Pipe, I googled and came up with this, there are tables showing weight's of certain size houses, might be of some help to you.
[PDF]
Characterization of Building-Related Construction and Demolition ...

amount of building-related C&D debris generated, on a weight basis. Tables A-1 through A-6. in Appendix A are worksheets that provide details of the ...

Pipe,
Scan the list. Email it to me. My email address is on the contact page of my web-site. Reference material I've got.
Stone/concrete 150 LBS/FT^3
Wood 28 LBS/FT^3
Steel 490 LBS/FT^3
PVC 90 LBS/FT^3
Aluminum 170 LBS/FT^3
Dry soil 100 LBS/FT^3
Water 62.4 LBS/FT^3
If you use this list, you can ballpark almost anything by using the most similar material on the list. For instance, figure dry soil as concrete or stone with air in it, wet soil as about the same as concrete. Loose plaster would probably be about the same as dry soil, etc...
Residential construction from the sill plate up
is seldom over 20 LBS/FT^2 of floor area (lifted a few, LOL).
Quick way-take a 12" or 16" or 24" slice of the structure, parallel to the joists, add up what's in it from the footings to the ridge, and go from there. Don't forget the end walls...
That should get you started.
-Michael

Reason: Meant "loose plaster."

AFTERTHOUGHT...
Pipe,
I know that YOU know this, but for other readers, dry concrete (solid) weighs about the same as wet concrete (liquid).

Thanks all of you for your feedback. Just in case your interested, I built a spreadsheet to estimate the weight of the structure. I broke down materials by CIS 'division' and here's what I came up with for this 28 x 35, 2-story, 1/2 basement, 1/2 crawlspace , no attic house with a single bathroom and 12 x 12 enclosed back porch:
29 tons of concrete (footings, area way, porch slabs and steps)
53 tons of masonry (foundation walls, 1st-story brick veneer, fireplace and chimney)
15 tons of wood
4 tons of dampproofing, insulation, siding, roof shingles, gutters and downspouts)
27 tons of finishes (plaster walls @ 10#/SF, ceramic tile, interior paint, pad & carpet)
I got lazy and ignored the M/E/P debris. The house has been stripped pretty good of any salvageable copper and the HVAC isn't much more than a couple ducts.
All tolled, thats about 130# per SF of footprint per floor (130 x 28 x 35 x 2).

I will find my book tomorrow and post the name of it. You can buy it at Home Depot, where I got it. Its about a half inch thick and has every thing you can imagine listed by weight and volume. I think it was $6.95. And it is what I use to estimate dumpster weights during my demolition. Hope it helps.

Pocket Ref by Thomas J. Glover is a good one, find it at the check-out in hardware stores. It's published by Sequoia Publishing in Littleton, Colorado.
I wasn't figuring the 2nd story, or any masonry.
Most of the stuff that we've lifted was built pretty light, that's why they needed so much work in the first place. The most we've lifted was 35#/FT^2 per floor from the sill plate up.
Yours sounds a little heavy. Maybe you're figuring a little high to cover yourself?
The last demo job I did was a 2 story post and beam barn about the size of your house. It had a 4' dry stone foundation, and was FULL of miscellaneous household type junk. It cost me about 8 grand total.
Do you have to have asbestos monitoring?
