Turns out the statement "Cracked Foundation" was an understatement....Hard to crack a foundation when one barely exists! Had the contractors (3) and one structural engineer out the past couple weeks with the following findings.
(1) The "foundation" under the dining room addition was little more than a rat wall, even under the Fireplace! Extending no more than 36" at its deepest (note Michigan winters) and no footings to be found in three exploratory digs. (including under the fireplace)
(2) All three contractors and the structural engineer came to the same conclusion that this problem needs to be solved at its root cause--Putting in a real foundation.
(3) This work as laid out will entail the following: a. Pull brick and chimney down to lessen weight. The general concensus was that if the ground goes before the brick, the brick/wall will come down on its own.
b. Dig out foundation
c. Evaluate best method for adding to existing foundation to create a usable foundation
d. Perform necessary concrete work
f. Rebrick, including chimney
In a nutshell, that is the game plan. In execution....I will find out this coming weekend (5/7/00) as the brick comes down.
