The General McIntosh and President Street Improvement project remains in the surcharge consolidation settlement period.  As planned, this period of time in the project schedule results in the least amount of observable activity.  Although the project doesn’t appear as active during this period, this is a very critical time of surcharge monitoring.  A determination must be made as to when consolidation settlement has been obtained.  If surcharge is removed too soon, future significant settlement of the finished roadway and new utility lines may result. Current monitoring results indicate the consolidation nearing completion, although additional monitoring over the next month or two may be necessary to ensure requirements have been met.

While awaiting consolidation settlement on the new roadway portions of the project, one crew continues to install new utility lines through the newly bored casing.  These casings are installed underneath the railroad tracks and new Bilbo Canal on the south side of President Street, just west of the Truman Parkway.  These lines include the 24” Water Main and 24” Sewer Force Main.  These two new utility lines (280’ each) were pressure tested last week with passing results.

In addition, the Bridge and Canal crew have finished installation of concrete canal walls on the south side of President Street and have moved to the north side of the roadway.  They have begun to install the eastern canal wall.  This work involves de-energizing the overhead power lines through coordination with Georgia Power, driving sheet piles to safely shore the excavation, driving H-piles (plum and battered piles) for the canal wall foundation support, forming the canal wall footer, tying rebar, and pouring concrete for the footer and canal walls.
