Been working on plans and ideas for almost a year now, and today the majority of the work was finished. I've spent a lot of time browsing this forum, looking for info an ideas, but like anything you hear/read online, its best to do your own home work.
This is part of a new home build, so it was from the start a made from scratch job. The first thing I can suggest to anyone thinking of building a vault is to forget everything you read on line, and hire a real structural engineer to design it. Give the engineer the drawings of where you want it and let him tell you your options. This cost me $800, to have my vault engineered but he brought up points and ideas that the builder and the foundation guy wouldnt have.
Going off the drawings, knowing how much weight we're talking about with the reinforced 8' walls, the vault has its own reinforced footers.
After the footers were set the forms went together for the walls.
The next day the forms came down and I could see the walls.
The black stuff is the waterproofing, the yellow stuff is some moisture resistant stuff, and it will be top offed with 6' of stone back fill. Doing about everything we can to make sure it stays dry.
Once the walls set, it was time for the top.
8 more inches on the top.
It was amazing watching how fast those guys moved and smoothed it out. After it sets a day they'll be back for relief cuts.
The stainless steel they used for the deck looks pretty cool from inside. I also had them add a drain for the dehumidifier. Still thinking about what to do with the interior walls. They will be studded, insulated and covered, but not sure with what yet.
The floor gets poured next week, and the door will be installed the day the framing begins. The door is coming from Smith Security Safes (local guy), who makes some really cool vault doors.
