Now
that surcharge placement on the project has been completed, earth work
operations have significantly slowed. As scheduled, the surcharge will
require a period of time for consolidation of under lying soils to occur.
It is estimated the surcharge will have to remain for four to six months before
consolidation settlement of underlying soils are complete. These results
will continue to be monitored through the use of settlement plates which are
positioned in various locations along the surcharge. The settlement
plates indicated significant settlement during the initial surcharge and wick
drain installation, but have now begun to settle at a much slower incremental
rate.
Additional
work has been completed near the New Congress Street and General McIntosh
intersection where crews have replaced curb and gutter, along with sidewalk at
the new roadway grade, on the east side of General McIntosh. This new
section of roadway received a base coat of asphalt to allow delivery trucks to
the Marriot access from the new Congress Street. This new roadway also
now provides access and shows how the entrance into the Savannah River Landing
development will look.
Crews
continue to jack and bore the final steel casing underneath the railroad tracks
and future Bilbo Canal, just south of President Street and west of Truman
Parkway. This crew has completed the 36” diameter steel casing for the
new 24” water main and 36” diameter steel casing for the new 24” sewer force
main. They are currently boring the last casing which will be a 16” steel
casing for the new 12” AGL natural gas main.
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 will be completed this week. When
completed, this crew will then shift back over to the western inner Bilbo Canal
reinforced concrete wall on the south side of President Street. The
schedule remains to complete the western inner canal wall on the south side of
President Street, and then move to north side of President Street to begin
constructing the eastern and western inner canal walls. These canal walls
will connect together eventually under a bridge to be built over the canal, but
will require future traffic shifts before that work can be performed.
A utility crew working on the far eastern end of the project
(near Truman Parkway) has completed a section of new 24” water main and is now
working on a new section of 24” sewer force main which will run parallel to the
water main. Once the section of new 24” sewer force main is completed,
this crew will be moving to the median of President Street (just east of the
Truman Parkway over pass) and will be constructing a water main tie-in.
This water main connection will connect the new 24” water main to the existing
20” water main located beneath the existing median.
