You really should read that containment procedures guide. Personally, if I saw this on the mainsite, I would have downvoted a few sentences into the containment procedures. The guide you were linked to mentioned "emphasizing plausibility and minimalism", which is… kind of the opposite of what you've got going on here.
I would have recommended this guide for containment: http://www.scp-wiki.net/doing-the-safety-dance
It's got more specific directions on how to make stuff believable. Right now, you've got a bunch of wacky instructions for things that I'm having a very hard time believing that the Foundation would actually try, such as:
The chamber has 3 double locked doors comprised of Reinforced Steel. They are required to have security monitoring equipment 10-20 meter spacing between the doors. Along with the following, 2 security guards with level 3 to 4 clearance are stationed at the main door. The chamber is comprised of 10 layers of Tungsten. Each layer is about 35 cm thick.
The actual size of the containment chamber isn't given, but given the "10-20 meter spacing", I'll assume that the entire chamber is built like a square, with doors in the centers of three of the four walls. This means that the security equipment can be kept in the corners, with the one wall with no door having some extra equipment in the center of the wall. That makes for about, say, 21 meters for each side of the square, assuming the door itself isn't more than a meter wide.
So that gives us a cubical containment with a surface area of roughly 2646 square meters by using 6(21*21), and converting that to centimeters we get 26,460,000 square centimeters. Multiply that by the thickness of the innermost layer, 35 cm, and we get 926,100,000 cubic centimeters of tungsten. Google tells me that tungsten's density is 19.3 grams per cubic centimeter, so that's 17,873,730,000 grams of tungsten, or 178,737,300 kilos. Tungsten doesn't naturally occur in its pure form so far as I know, but according to the internet, "the majority of products in the $100 to $350 per kilo range". We'll assume the Foundation is being thrifty and going for the $100 per kilo price, but they'd still be paying well over a billion dollars for this this layer of the containment chamber, and there's still nine more layers to go, each thicker than the one before because the outermost layer is going to contain a lot more tungsten than the innermost layer.
ETA: someone can (and should) check my math on this.
ETA 2: Yeah, I didn't take out the amount of material that the doors would be taking up. It's a rough estimate.
And that's not even taking into consideration the lack of proper capitalization ("reinforced steel") the wrong use of "it's" (only use that when you can replace the word with "it is") and the strange need for Level-3 and Level-4 security personnel who are probably better stationed elsewhere, like leading teams they should be assigned to.
Personally? I recommend getting the base idea polished up in the Ideas and Brainstorming forum before you try fixing the draft. Go to that forum, post a quick summary of the concept you want to write up (don't link the draft unless someone asks), and reviewers there can help you make the idea more interesting and give you some advice on structuring the eventual article for smoothness of reading and narrative.
