Building Over An Existing Problem
Building Over An Existing Problem
(OP)
We are the structural engineer on a new heavy construction project (7 floors of PT garage with 3 floor of residential aobve). There is a small 150x50 single story build on one edge of the site. The developer is unable to remove one of the tenants and therefore is asking us to design and incorporate a shelter structure around this existing building. A couple of questions, first does anyone know if there are any provisions in the code that would require the tenants to vacate while we construct the shelter? Second any code provisions that would require them to vacate during the construction of the entire project? Lastly should we acutally have to go through with building the shelter, any recommendations for loadings, details or advise would be helpful.
Thanks is advance for any response.

Sounds like the owner/contractor needs to do some due dilligence here with his lawyer and hammer this thing out legally, as I do not think you will find your solution in the code.

I can't find the pictures. They built a steel frame around and over Vera Coking's house, then went out of business so it stayed that way for a few years.

JAE...this is in your area...where are ya?

If the single story owner ever sold his property to someone else in the future, any vertical development would obviously be limited by the building above it, depending how much there is.

After reading your post carefully, I have a few questions:
1. Is the 150 x 50 building under your new construction or just beside it? You don't directly say.
2. Is the shelter to be constructed beside the tenant's building to avoid potential construction materials from accidently being dislodged and perhaps damage the tenant's building? Or is it to shelter from falling debris, tools, etc.?
3. Is the shelter intended to be permanent or just there during construction operations?

Also, there is the basic common sense that you would be taking on a great deal of liability with heavy construction going on overhead of occupied spaces.

Back to first principles - how high can things fall, what is the maximum weight of the dropped item and how far will the barrier flex.
Just remember that deflection is your friend when it comes to impact resistance.

a few years ago on the gulf coast (back when economy was booming and condos were actually getting built) it was not uncommon for an owner of a small beach house to block the use of tower cranes on the condo being built next door.
one little old lady next to the project I was working on thought the counter weights would fall on her house. not that I've heard of that happening, but nothing's impossible.
