used as the design storm. The resulting raise in track was nearly
three feet, requiring almost a half-mile of track realignment. An
open deck system was selected to minimize the required track raise
and to permit access to the steel floor system for maintenance.
Bids were received on June 5, 2013, and the project was
awarded to Glenn O. Hawbaker, Inc. (GOH) of State College,
Pa. on June 30, 2013 with a total bid of $9.1 million. High Steel
Structures, Inc. (HSSI) was the steel fabricator and K.W. Reese
performed all track construction. Construction started immediately
to meet the 12-month construction schedule, and several
challenges were encountered that required immediate coordination
between the contractor, engineer and owner to maintain the schedule.
These included the following.
Cofferdam construction for east abutment and
both piers
The cause of the original bridge failure was stream scour due to
flooding and undermining of the piers. Both of the new piers were
designed with sheet pile cofferdams by GOH and cut off underwater
by divers and left in place for protection for future flooding
and scour protection. Also, temporary sheet pile cofferdam
was designed by GOH and utilized for the construction of the
east abutment. PZ-27 sheet pile cofferdams were installed using
a Link Belt 80 ton and 110 ton crawler cranes and International
Construction Equipment (ICE) model 416L & ICE model 28B
vibratory hammer.
Both east and west abutments and the two pier foundations
were supported on steel H-piles with attached hard bite H-pile
point driven to bedrock, for the added scour protection. Piles were
installed with the Link Belt 80-ton and 110-ton crawler cranes and
ICE I-19 diesel pile hammer and leads. Bearing pile material used
13,338 feet and 1,120,400 pounds of steel HP12X84 H-piles and
603,180 pounds of PZ-27 sheet pile. All piling material was supplied
by Skyline Steel, a Nucor company.
Vibration monitoring and protection control plan
Due to the location of the two gas transmission lines (Sonoco
Logistics’) and force main sanitary sewer line and sanitary sewer
line on the upstream side of the structure, the owners of these lines
required a vibration monitoring control plan, which was developed
and approved. Vibration monitoring was done during installation
of the sheet pile cofferdam and H-pile installation.
