Swan Creek Lake Crossings
Sunbury County, NB
Eastern Designers & Company Limited performed value engineering, as
well as the final design and preparation of contract documents for
these two $6M, 157m long structures, part of the Fredericton-Moncton
MRDC Highway project. The superstructures consist of 4 span
pre-cast, pre-stressed 1900mm deep bulb tees. Technical challenges
included designing the substructures for a very soft and deep
overburden requiring monitored pre-loading, tied-back abutments and
sleeved piles. In addition, the river piers had unique pipe piled
elevated bath tub type pier footings which precluded the use of more
expensive deep seated steel sheet piled cofferdams. |
