lumber for shop, What price board foot.? green lum

If the building is not a live in dwelling you may be able to use ungraded lumber. Talk to your building inspector or a local engineer varies from town to town and end use of structure. It'll cost around $300 to have a house worth of lumber graded. It can be done standing in a pinch.

Around here white pine, hemlock,spruce,poplar are using for framing lumber. When using spruce look for 7 growth rings per inch or more (same with pine).
The cost of lumber. If you have trees or can get trees worthy of milling into lumber a portable mill can mill 100 -300 bdft of lumber per hour (if not more). A full 2x6 -8' is approximately 8bdft a finshed 2x6-8' is approximately 6bdft in it. If I'm milling framing lumber I tell the customer there paying between $.08 and $.30 per bdft cutting there trees. (Depends if were cutting 2x4's or 2x12's -- larger the board the less cuts .)
KD framing lumber can range from 10-20% moisture content. What the kiln drying is doing is setting the pitch and killing the bugs. White pine and hemlock stickered and stacked properly can be ready to use in a year (if milled to finished dimensions). Go over to>Link
Numbers fluctuate. I don't sell framing lumber but will sell timbers for timber frames and siding. Not much profit in selling framing lumber. On site milling is the way to go if you have the trees,time and are into that kind of stuff. Its not for everyone. Were you talking about the GREEN lumber depot is selling? If so sorry for the long post.

Here in the People's Republic of Connecticut, rough sawn Hemlock (the framing of choice) runs about 50 cents/bft.

Many towns in the Republic will not allow the use of native lumber for framing. The building inspector in our town will, but it has to be racked, air-dried and graded by a certified professional before use.

We put up 2 barns on my place in past 4 years, 2 floors, pole construction using pressure treated posts, kiln-dried (western) framing, 10 pitch roofs with 40 year asphalt shingles and native white pine trim and siding (shiplapped). The basic shells (no concrete floors, doors or mechanicals) cost $13.50 and $15.25 per square foot respectively, labor and material.

All the native lumber we use gets racked and air dried to less than 10% moisture before use. I would not recommend using green lumber due to shrinkage and twist.

Good luck,
Scott

Last year I managed one batch of 10 foot 2X4's cut out of pine for .50/bd ft, but usually I have to pay 75 to 90 cents per.

Used sensibly, green timber can work fine for framing. Just don't leave any spruce exposed to the sun before sheeting it.
