High Speed Rail Road, Madison - Watertown,
Wisconsin |
|
| |
|
 |
The
existing Canadian Pacific and Wisconsin Southern
railroad between Milwaukee and Madison was being
considered for improvement to accommodate the
proposed (currently on hold) high speed rail
between these two cities. GESTRA's scope of work
included subsurface exploration and laboratory
testing of soil for several rail bridges,
culverts, retaining walls and rail/embankment
widening for the High Speed Rail (HSR) project.
Field investigation scope included over three
hundred explorations including soil borings and
cone penetration locations. Laboratory services
included tri-axial, consolidation, permeability,
soil index properties and chemical analysis for
soil corrsovity. |

Butterfield Road Widening Lake County, Illinois |
|
| |
|
 |
Butterfield Road in Lake County, Illinois,
from station 121+50 to station 200+00, was
widened with new curb & gutters. The total
project length was about 10,250 feet. The
reconstructed road has five lanes, including
a center turn lane. Paved shoulders were
added as an improvement from the existing
condition. Gestra Engineering performed the
geotechnical drilling, laboratory testing of
soil, and prepared the geotechnical
engineering report |

US
41 Corridor Improvement, Brown County, Wisconsin |
|
| |
|
 |
The
US 41 expansion project in Brown County,
Wisconsin extends from Orange Lane at the south
project limit to Lineville Road (CTH M) at the
north end, over 14 miles. The objective of this expansion
project is to accommodate more traffic and
provide safer and easier travel. Key features of
the improvement plan include interchange
upgrades, added lanes and construction of
roundabouts. Ten Hwy 41 interchanges are being
planned for upgrading/reconstruction in Brown
County. GESTRA’s scope of work includes
performing subsurface exploration, geotechnical
engineering analysis, and preparing structural
geotechnical reports (SGR) for 23 road bridges,
38 retaining walls and 12 sign bridges. |

I-94 North South Corridor Widening, Milwaukee –
Kenosha, Wisconsin |
|
| |
|
 |
The
I-94 north-south corridor, a 32 mile section of
interstate in Kenosha, Racine and Milwaukee
Counties, is being reconstructed. The project
includes adding one lane in each direction,
reconstructing the Mitchell Interchange and
reconstructing most of the structures between
the Mitchell Interchange and the state border
with Illinois. GESTRA performed more than 1000
borings for a total of over 40,000 lineal feet
of drilling and monitoring well installation. In
situ-testing included pressuremeter testing.

135th Street Reconstruction Will County,
Illinois |
|
| |
|
 |
135th Street in the City of Lockport, Will
County, Illinois, from New Avenue to Archer
Avenue, was widened with new curb & gutters.
The reconstructed section of the 135th
Street has been upgraded from a two lane to
a four lane urban highway with a left turn
median lane. Retaining walls have been
constructed at several locations. GESTRA
Engineering performed the field and
laboratory soil testing and prepared the
geotechnical report |

Good Hope Road and Brown Deer Road Bridges over
I-43, Milwaukee, Wisconsin |
|
| |
|
 |
Proposed improvements at Good Hope Road and
Brown Deer Road bridges over I-43 in Milwaukee
County, Wisconsin include of reconstructing the
existing bridges with longer spans to
accommodate additional lanes on I-43. Exit and
entry ramps from and to I-43 will also be
realigned. Mechanically stabilized earth (MSE)
walls will wrap around the new bridge abutments.
Gestra Engineering performed the field and
laboratory testing of soil and prepared the
geotechnical engineering report following the
Load and Resistance Factor Design (LRFD) method.

Elm
Road Power Generation, Oak Creek, Wisconsin |
|
|
|
 |
GESTRA had been Completed
a total of 47 standard penetration soil borings
to depths varying from 20 to 100 feet, for a
total of 2750.5 lineal feet of drilling.
Boreholes were advanced using hollow stem augers
(4 ¼” and 2 ¼”) until saturated sands were
encountered that required mud rotary drilling
and were abandoned with bentonite slurry in
accordance with applicable WDNR regulations.
Four soil borings were performed offshore in
Lake Michigan using a barge.
Performed Pressure Meter Test in three boreholes
at two elevations in each of these three
boreholes. Data interpretation and reduction was
completed by GESTRA Engineering Performed
laboratory soil tests to assign classification
and engineering properties to the soils
encountered. |
