Concealed Condition Notice Before Disturbance

In construction contracts, what is a 'Type 1' differing site condition?

If an electrical crew digging a trench encounters an unexpected, concealed underground foundation, they can claim a Type 1 Differing Site Condition even if the contract documents did not include any soil reports or site descriptions.

Watch the provided video segment to understand the two types of differing site conditions. Then, match each field scenario encountered by an electrical crew with its correct contractual classification.

An electrical contractor trenching for underground conduit encounters an unmapped, dense rock formation. Arrange the steps the contractor must logically follow to analyze the situation and establish a Type 1 differing site condition.

Upon evaluating a rejected change order for unexpected underground water encountered during conduit trenching, an electrical contractor realizes the owner's rejection is valid because the original bid package included no soil reports to contradict. To successfully defend an appeal, the contractor must pivot their strategy and evaluate historical local data to prove the water level is of an unusual nature and not ordinarily found in that area, legally justifying the appeal as a Type ____ differing site condition.
