   If you send me your email address, I will send you contact info for specs re: on-site construction of long-span beams made from lightweight dimensional lumber.

   Additional info: Just wanted to have 9 to 12 feet open on span. Some areas are exposed from below and the overall need is just a attic space/loft for extra space/kids if needed.

   I plan to laminate and/or plow out logs and attach on exposed trusses/rafters (I apologize) I use them interchangably.

   I am replacing log rafters after 60+ years that have given signs of imminent trouble. "red squirrels"

   I wanted to find information on building roof trusses for my cabin and wanted to perhaps open up space in them for a small sleeping loft in the construction. I sort of got the "cold shoulder" from a couple of truss companies and engineers about prefabrication just short of assembly or when I wasn't going to buy trusses from their company. I would normally buy them, but these have to be built on site (a island) and from materials I haul by boat (10 mi.) or fly in. Nothing exceptional in size - 16' load spans 24' spans overall. Slope and dormers negotiable.

   Are there any good detailed articles, books or reasonable software or add on's to AutoCad that would give the plans and enough Min/Max loading, span and materials to ensure good construction and life to keep me from over building these. I am not required to have an engineering review stamp, just to keep the things away from the lake, and be darn sure to get a permit to burn a tissue. I have built a good number of these before but just wanted some support to go with and haven't seen a article in FH that would lead me to the fountain of knowledge. How about it discussion groupies?

   Or should I spend the $250 with a engineer, get a drawing on a napkin and pat on the back? Money is not the object, just getting the things in place is.

   *Mr. AndersonThe sizes that you indicate are not difficult to deal with. The lack of pertinent information makes it difficult to give an informed answer.If you want to make full use of the upper level then you would be wanting information on site installed roof joists or rafters, not pre-engineered roof trusses.If weight is a problem, you should contact your local lumber yeard nearest your project and ask them about using engineered joists in the roof assembly. The costs is a little more but the weight is less and the comparative strenght to wood is better. They should be able to supply you with technical information on the load and span limitations.Hope that I could be of helpGabe Martel GSCProject Manager
