Explanation
BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the construction contract with Shelly & Sands, Inc., for the Champion Ave. 24" Water Main Project, for the Division of Power and Water.
This project consisted of constructing a 24-inch water main along Champion Avenue from Maryland Avenue to Main Street. During the construction, a number of unexpected underground utility conflicts were encountered that significantly increased the construction cost of the project.

Due to other utility constraints the proposed water main could not be relocated to avoid the abandoned gas main. This necessitated the removal of the gas main. There wasn't a record of the sanitary sewer, so it did not appear on the construction plans, nor was it evident in the field during construction of the water main.

The contractor repaired the sanitary sewer, but the cost to do so, was not a part of the original contract. Finally, the Department of Public Service requested additional pavement replacement above and beyond the quantity shown on the plans approved by the Department of Public Service.

4. How cost of modification was determined:
