overhead, profit, etc. and there will be no other compensation. This Change Order hereby incorporates the
original contract and all its referenced documents' terms and conditions.
Justification for Change:
During the concrete pad excavation, the contractor encountered unsuitable material. The material has to be

concrete pad with a thicker base.
