The initial one foot of sand layer has been mostly completed along the south side of President Street, topping the backfill. This sand layer provides the bed necessary for the wick drain installation. The wick drain contractor should be arriving onsite late next week or the following to begin installations. Installation of the wick drains and placement of additional surcharge material will begin the predicted approximate six months of settlement/consolidation of underlying soils. This settlement/consolidation of underlying soils must occur prior to installation of additional utility lines and roadway construction to prevent settlement and damages to these future installations.

AT&T continues to work on the removal/relocation of their communication lines along General McIntosh. Now that a portion of these lines have been removed and/or relocated, undercutting and placement of backfill on remaining areas of General McIntosh has begun.

New Congress Street and General McIntosh Boulevard intersection has been graded to approximate roadway subgrade elevations. Once elevations in this area are checked and verified, crews will begin to layout and install curb and gutter along new Congress Street.
Following pressure testing, flushing, and chlorination of multiple new water mains along General McIntosh, these lines have begun to be connected to the new system and old lines cut and capped. Redirecting flows from the old water mains to newly installed lines provides an upgraded infrastructure, but also allows the removal of old mains to allow undercutting, backfill, and surcharging of the new General McIntosh roadway alignment.

Jack and bore of steel casings underneath the railroad tracks and future Bilbo Canal, just south of President Street and west of Truman Parkway continues. The bore pit in this location is being excavated to the depth necessary for installation of bore casing below the future Bilbo Canal and railroad tracks.

Construction of the Bilbo Canal and President Street bridge over the future canal continues.   Following installation of steel H-piles to a depth of approximately 65’, crews tied rebar and set forms to pour the concrete footer for the future Bilbo Canal wall that will rest on these steel H-piles. An initial section of the canal wall footer was poured earlier this week. Next the concrete wall above the footer will be poured, and an additional section of the canal wall will begin starting with the installation of additional H-piles.
