Was it holding up the beam before this happened? 

Sarah, I use a laser measuring device..

I was laser focused on the development business, which undoubtedly shaped me into who I am today.Nowadays I have the experience and confidence to expand into other niche's (I've recently bought and sold a couple of medical condos for example).

Laser focused on long-term "passive income" and generational wealth.

even a $200# punching bag and a big guy pounding away daily should not do a thing o a properly structure steel I beam....

They won't help if you've got a big sag in your roof, but if it's just a small dip between the beams it will become harder to pick out.

Spent $7k turning the old junky basement into industrial-chic-cool with exposed wood beams, lots of shiny new electrical outlets via exposed conduits and OSB (pressed wood) for the sub floor.

Trusses come with their own engineering and my truss provider can calculate beams for me when needed. 

Because of beams, the kitchen ceiling is sub-divided into nooks. 

Another question I have is once the property is sold, suppose 5 years later a rafter or beam falls on somebody causing injury and the original contractor is long gone which happens a lot in this business.
