What happens if there are any deviations to the sub-surface conditions?

If, during the progress of the work, sub-surface conditions at the site materially different from those shown on the Drawings or indicated in the Specifications or in any Contract Document, are discovered, the attention of the Owner shall be called to such conditions before they are disturbed.

 

The Owner shall thereupon investigate the conditions, and if he finds that they differ from those shown on the Drawings or indicated in the Specifications or in the report of the Owner's geodetic survey and sub-surface exploration, he shall make such changes in the Drawings and Specifications as he may find necessary.


If as a result of sub-surface conditions, additional or a different type of work be required, although no change in the Drawings or Specifications is made, a Change Order shall be necessary and issued to the Contractor.
