Wood Screws are covered by ASME B18.6.1. Note that there are two types of threads - cut thread and rolled thread. Cut threads have tapered shank, rolled threads have a constant shank diameter and taper at the point. The design steps and allowable values for use in wood structures is...

The answer to your first two questions is no - mixed material types are permitted and indeed, used all the time. The code only prohibits the use of combustible materials for a couple of building types: high hazard facilities (H-1) and some institutional facilities (I-2). The code...
KB4444:
To better understand the issues I would carefully review the definitions in 101. An exit should be defined in there. Generally it's a point where one enters an outdoor public way - where a person is "safe". Catwalks and such are not usually considered "occupiable spaces" - people...

The deck looks similar to the Tectum system. Link I'm not familiar with the joist system, but the Tectum product has been around for nearly 70 years so it may be a legacy system.

Ive never had to deal with a very tall fire wall. The general approach is to use a single wall that is braced by the structure on both sides. The trick is to detail the braces as break-away connections, as Dik mentions. It sounds like you have a complicated project. I'd suggest...

Assuming you're in the US, the definition of a fire wall (not fire partition) in the IBC states: "FIRE WALL. A fire-resistance-rated wall having protected openings, which restricts the spread of fire and extends continuously from the foundation to or through the roof, with sufficient...

I'd be very careful with this approach - if the house is air conditioned, you'll almost certainly have moisture condensing on the underside of the floor sheathing with the resulting conditions LuK13 mentioned. The moisture comes from the outside air that's brought in through the code...

If you look at IFC 905.1 General, the language states that "Standpipe systems shall be provided in new buildings and structures in accordance with this section." The plants you're working on aren't buildings, as defined by the building code, but, they definitely are structures. As...

I've seen discussions of "portable" water jet cutters This would be you best bet if the process is truly portable. Another option is wire saw. The quarrying industry uses these. They make smaller portable units that would work for that. Here's an example: Link

The building will almost certainly see condensation on the underside of the deck - I'd treat it. The presence of the wood panel will, to some extent, ameliorate the condensation since it has a much lower thermal conductivity than the metal roofing. Metal panels on purlins (no...

Cummins allows black iron Sched 40 on their systems - so it's probably ok. But, I'd check w/the manufacturer of your gen set to verify.

We've never used the mesh systems supplied by the tubing manufacturer. My understanding is that those systems are for larger spaces (>10,000SF). We've always secured the tubing to the 6 x 6 steel reinforcing mesh. Also, we've not used the system of anchoring the tubing to the...
JLSE:
Radiant systems nearly always use a water or water/glycol solution as the medium. Leakage in the system is pretty rare. Leaks are usually caused by contractors drilling into the floor or saw cutting the slab. You shouldn't need a topping slab. The tubing (nominally 3/4" OD) PEX is...
