At this time, surcharge material placement has been completed across the entire project (south side of President Street and General McIntosh), except for a small section of the south side of President Street towards the Bilbo Canal. Placement of surcharge over this portion of the project has slowed to ensure the consistent vertical settlement of underlying soils. The movement of underlying soils in this area are being monitored, and indicate much greater settlement up to this point than other areas. As settlement rates for this area become more consistent with other surcharged areas, the final lift of surcharge will be placed. Now that the majority of surcharge has been placed, the settlement of the material will continue to be monitored. It is predicted the surcharge may have to sit up to six months to allow for complete consolidation of underlying soils.  Continued monitoring results by geotechnical representatives over the next few months will provided the data for making a determination that consolidation settlement has been reached, and surcharge material can be removed.  To provide a temporary cover and help with the stabilization of surcharged areas during the consolidation period, the contractor has applied grass seed and straw mulch over the disturbed soil areas.

Additional work continues at the New Congress Street and General McIntosh intersection as crews remove and replace curb, gutter, and sidewalk along General McIntosh.

Crews continue to jack and bore steel casings underneath the railroad tracks and future Bilbo Canal, just south of President Street and west of Truman Parkway. This crew is now installing the steel casing necessary for the installation of a new 24” sewer main.

Construction continues on the new reinforced concrete Bilbo Canal walls. Additional sections of the eastern Bilbo Canal wall have been poured. Construction of this eastern canal wall will continue south from President Street over the next few weeks. Eastern and western canal walls will be built south of President Street before the crew moves to the north side of President St. to construct those proposed canal walls.

A utility crew continues with the installation of new 24” water main on the far east end of the project (east of Truman Parkway and south of President Street). Once the 24” water main is installed in this location, this crew will then begin the installation of a new 24” sewer main which will run adjacent to the new water main.
