Instead of complete removal from the project, the waterline alignment was modified to allow for a looped system in the neighborhood. $39,238 contract increase.
Change Order 2: Covers remobilization and work performed on the old waterline before the alignment was modified. $0 contract increase.
Change Order 3: Due to the age of the existing waterline in the neighborhood and some unforeseen conflicts underground this change order had to be issue.
