NORTHWEST
SIDE RELIEF SEWER TUNNEL
Milwaukee, WI
The $117,000,000 project consists of 37,430 feet
of 20 foot diameter tunnel, constructed in rock
at depths of 140 to 180 feet. Engineering Partners,
working for Shea/Kenny Joint Venture, who are building
the project, performed pre-condition surveys at
the sites of all shafts. Engineering Partners also
installed piezometers into the bedrock at each shaft
site to monitor the effects of dewatering activities
during the construction process. |
 
DOCK
WALL
Erie, PA
Engineering Partners was retained as a subconsultant
to assist in the investigation and remedial design
of a 34 foot high x 500 foot long section of dock
wall, which had failed. The first task for Engineering
Partners was to plan a geotechnical investigation
program of boring and test pits and to prepare technical
specification for the work such that a driller could
be hired. Engineering Partners then provided field
oversight services during execution of the investigation
program, including test pit logging and observation.
A summary report of conditions was prepared. Once
a decision to proceed has been reached, Engineering
Partners will design the tie-back system for the
new wall. |
PRIOR
LAKE OUTFALL
Scott County, MN
Engineering Partners is the geotechnical and structural
engineer for a new outfall structure and open channel
watercourse. The new, reinforced concrete outfall
will be placed in the lake, approximately 30 feet
offshore, to control lake water levels and minimize
potential flooding along the highly developed shoreline.
The new outfall will connect to an existing concrete
pipe outlet, which carries the lake overflow to
a series of detention reservoirs, one to two miles
west of the lake. The open channel watercourse connects
the reservoirs and will replace an existing CMP
conveyance pipe.
Lake bed deposits at the site of the new outfall
consist of loose to soft lacustrine soils and colluvium,
which complicates the design. To compensate for
the poor soil conditions, Engineering Partners has
specified a surcharge program to precompress the
deposits prior to building the structure. In addition,
flexible connections will be utilized to connect
the existing pipe in the event that long term differential
movement occurs. |
CROWN
HYDRO
Minneapolis, MN
Engineering Partners is the prime consultant and
engineer for the redevelopment of the Crown Roller
Mill at St. Anthony Falls on the Mississippi River.
The $8,000,000 project, when complete, will produce
3.2 megawatts of renewable electric power. Engineering
Partners has completed preliminary engineering and
permitting studies, including cultural resource
investigations and fishery mitigation studies, and
is now working on the final design. The final design
will involve a 57 foot deep cut into bedrock for
installation of the the turbine and penstock. The
firm will serve as Construction Manager when the
project moves to construction. |
