Need some help on a take home exam question. Thanks in advance.

Construction is 80% complete on a 100,000 sf building (like the new bioscience building you toured). The architect was performing an inspection when a concern was raised about the exterior wall framing. There seems to be some mold starting to appear between the insulation and the concrete exterior walls and also the exterior sheathing on the upper walls. The mold is not everywhere, very spotty, but located on every floor.

The typical exterior walls in the basement are 8” cast in place concrete with 6”metal studs and R-19 insulation. The upper floors’ exterior walls consist of 18 gauge metal studs with R-19 insulation with a 6 mil draped vapor retarder. The exterior sheathing is 5/8 USG exterior Fiberock brand Aqua-Tough sheathing panels and the interior is 5/8 USG Fiberock brand Abuse-Resistant Interior Panels.

My group has some ideas but no structure to our answer yet. Any help is greatly appreciated.

I have painted an old cast iron fire surround in black metal paint, I like it but it`s a bit too `new` looking, how can I make it less shiny and a bit more authentic.

Mary J asked:


I know there is a wood pellet basket to use in wood stoves, but it doesn’t fit in my stove. Also the cast iron victorian fire baskets are nice but pricey.
Can I just make a pile in the bottom of the wood stove or would the amount of heat produced melt the metal?

DIY Metal Casting

crzy4wlvs asked:


I was wondering if there was anyone out there that would be able to tell me how to identify different kinds of metals.

The other day I was taking down my sons old rusty swing set and I was told to take it to the scrap yard. When I took it to the scrap yard they told me it was worth $1.00 per pound. I walked away with $248 for an old rusty swing set.

I own about 110 acres of land that used to be an old junk yard. I have tons of old metal that I want to take to the scrap yard but I do not know how to identify the steel from the stainless, iron, rolled steel, short steel, cast iron, ect….

I want to gather the stainless and short steel as it is going for more than the rolled iron.

Does anyone know how to tell the difference?

P.S.
I do know the difference between Brass, copper, Aluminum as those are easy to distinguish..
Thanks

It’s really old and really heavy. It’s been behind my shed for years and I’m wondering if it’s worth moving. I have a bunch of scrap aluminum pipes and other scrap metal I’m taking too.
