Sloping Floors

A major structural problem resulting from the swelling clays is that the south side of the building has been lifted significantly upward upwards. This has had many ramifications on building stability, but one of its more striking manifestations is that many floors now dip stongly towards the north. Here are some photos showing the slope and what needed to be done to keep equipment, such as a fume hood base, reasonably level. An east-west trending crack system runs most of the length of the building and out into the parking lot. Vertical displacement along one side of the crack, as shown in the crack photo, can be over an inch.
