Hey guys, a little background on the situation that was brought to my attention today. Last fall I was approached by a homeowner who bought a property with a home on stilts (12 L4X4X1/4 on 12"X12"X12" footings). The supporting footings if you want to call it that were way undersized, access...
Hello Eng-tips,
I was approached by a local Gym owner that would like to expand their operation. They own an ~100 years old adjacent building, the ceiling is too close to the floor for the equipment they would like to place in the gym and the walls are made of brick (opposed to brick veneer)...
