Recommend approval of Contract Modification No. 1 for the Bilbo Canal Drainage Improvements project to Orion Marine Construction, Inc. in the amount of $1,938.59. This modification also adds 60 days to the contract completion time.

The original contract was for construction services for the Bilbo Canal drainage improvements. The area of improvements to be made is bounded by the Savannah River on the north, President Street Extension on the south, East Coast Terminals property on the east, and the Savannah River Landing development on the west. The canal’s capacity is designed for a high tide during a 100-year storm (10 inches of rain in a 24-hour period). When completed, this contract will provide a sheet-pile walled canal 90 feet wide, seven tide gates at the river, a concrete bridge for accessing the tide gates, and a 20-foot-wide maintenance road on both sides of the canal.

This modification is needed to address several items. The modification includes the addition of steel pile for foundation support along the eastern flood wall, and the addition of two 12-inch water main gate valves. This modification also includes several items that have been deducted from the contract. Those items include deductions for a section of the 8-inch water main over the proposed bridge, deductions for the replacement of Georgia Power duct bank sections with the newly relocated Foundry Street, and credits for actual installed lengths of sheet pile and H-pile that were less than the original lengths in the specifications.This contract modification also changes the contract completion date to January 19, 2019.
