Here is a question from a reader:
HI ANDREW, I HAVE THE THREE PART VIDEO SET AND WAS TRYING TO GET THE BALL ROLLING ON A 30X35 GARAGE W/ BONUS ROOM ON TOP.THE INSPECTOR WANTS TO SEE ENGINEERED DRAWINGS. WHAT DO I DO? THANKS FOR NOW. ROB
You may have a need for an engineer to get the inspector into a place of comfort. Depending on your system, you may also be able to get by without an engineer. If you use the welded wire mesh engineering as shown in the video, you can go to www.EcoBuildNetwork.org and download the engineering testing from the site. This will show the inspector that you are not just making this stuff up! the name of the file you want is something like “Cyclic Testing in Straw Bale Walls” and it is found under the straw bale test results button on the right hand side of the home page (it has been a while since I visited the site so the layout may have changed).
Another option is to use HardyFrames for your shear engineering (www.HardyFrame.com) This will ensure that the shear design is covered by a tested and accepted material that the inspector will understand and perhaps even know. Assuming that the rest of your framing is simple, there should be no need to engineer the building. Roof trusses are covered by the manufacturer engineer report and you can get your lumber yard to create an engineering report per the manufacturer for the floor framing. Wall framing is the only potential spot for concern at that point and the beam sizing is pretty simple to do. A quick conversation with an engineer or a look through the span charts for beams within the code book should allow you to take care of that. Good luck.
