I have been asked to design a townhouse unit that will be constructed on the rear side of an existing townhouse building.

Is there a way to get a 2-hour firewall without having to redo the...
I was asked to design a pole barn and I have always passed on these type of projects because my calcs don't seem to match what the contractor says they want to do and what has worked for them in the past.

I am working on a basement renovation plan where the owner would like to remove a column and install an lvl beam in place of the existing four ply 2x10.
There are joist hangers on each side of the four ply 2x10 beam.

A client wants to remove some walls and install lvl beams to open their floor plan up.
The point load on a column on the 1st floor would support a 3,821 lb load.

See the attached sketch. My client is removing the existing foundation wall and pouring a new wall. The contractor just proposed keeping the existing footing and slab and installing some compacted stone to match the top of slab height and then pouring a new footing on top of that.

Do these cracks look concerning or are they just superficial?

I was contacted by an individual who is constructing a barn with a gambrel style roof. He is using pre-engineering gambrel roof trusses. He asked if he could use 3/4" pine boards (8" wide) for the roof sheathing. He would install them tight together(not spaced apart like strapping). The boards...
For a 40'x80' slab that will have a skid steer driving on it multiple times per day would you recommend going with a 6" slab instead of a 4" slab? Would you use rebar instead of 6x6 woven wire mesh?
The skid steer with the weight it is carrying would be around 15,000 lbs.
Thank you for the help.
I prepared a set of plans for a deck and the client and contractor change things during construction.

Instead of cantilevering the floor joist out two feet they cantilevered them out 5 ft and now want to add live loads.
Therefore a double LVL beam will be installed at...

The owner prepared the plans himself...
I am trying to keep my beam pocket where it is so the contractor doesn't need to buy 14' long floor joists and cut off over a foot. The location it is in now allows the contractor to buy 12' and 14' long joists and not have to cut them at all.
However, this only leaves 1.5" of concrete on the...
See the attached detail. The contractor used purlins instead of plywood so the 4' of fire retardant plywood was not installed. So a fire could burn up and over the fire wall due to the purlins. Is there a way to remedy this other than removing the metal roof and plywood and installing the four...
