Overall activity on the project has slowed some, but although you don’t see as much heavy equipment up and down the site, after placement of the surcharge material on the south side of President Street and along General McIntosh it is now doing the work for us.  This material is consolidating the soft underlying soils to provide a good foundation for utility line installations and surface roadway improvements.  Settlement plate and inclinometer monitoring continue on a weekly basis to determine when the consolidation of underlying soils has been accomplished.  Significant settlement was observed in the beginning, but as anticipated, the rate of settlement has slowed significantly. 

Crews working on the utility line jack and bores underneath the railroad tracks and future Bilbo Canal have now completed all three bore casing installations.  This crew will now be installing the new water and sewer mains through the casings and laying new mains adjacent to the bores.  These new water and sewer mains will connect with other newly installed mains continuing underneath the Truman Parkway and further east.  The third casing, installed for Atlanta Gas and Light’s 12” gas main, will now require installation through the casing to relocate the existing gas main outside of project conflicts.

Construction continues on the new reinforced concrete Bilbo Canal walls.  The eastern inner Bilbo Canal reinforced concrete wall on the south side of President Street has been completed.   This crew is now working of a final portion of the western inner Bilbo Canal reinforced concrete wall on the south side of President Street.  In the next two or three weeks, this crew will have the inner canal walls on the south side of President Street complete, and will mobilize a crane to begin construction of the inner canal walls located on the north side of President Street.

A utility crew working on the far eastern end of the project (near Truman Parkway) has completed a new section of 24” water main and is close to completing an equal length of new 24” sewer force main.  This crew will soon be moving to the median of President Street (just east of the Truman Parkway over pass) to construct the required water main connection.  This construction in the median will require the connection of a new 24” water main to an existing 20” water main running along the median of President Street.
