Maxwell-Potter Riverwalk Bridge

By

Maxwell-Potter RiverwalkWestbrook provided services from survey, bridge and trail design, through bidding and construction inspection for the recently completed Maxwell Potter Riverwalk.  The project was a cooperative effort with the City of Baraboo, Baraboo Kiwanis, and the Wisconsin Department of Natural Resources all contributing to the project.
This trail and bridge connect the Maxwell Potter Conservancy with the Baraboo Riverwalk and has proven to be a popular trail with locals and tourists alike.

Engineering Transport Services

By

transportation inspectionWhen a one of the nation’s largest refinery owners required expert bridge engineering coupled with heavy lifting and transport services, they selected the team of Westbrook Associated Engineers, Inc. (WAE) and Mammoet for this task.  The scope of work involved transporting two massive reactors across a 1980’s era county highway bridge utilizing SPMT (Self Propelled Modular Transports) from a rail siding and then erecting them at the refinery site.  The total weight of each reactor and SPMT configuration to be transported across the county highway bridge was approximately 1,500,000 pounds.

WAE inspected the existing highway bridge structure per FHWA guidelines, performed a series of refined structural analysis in order to ascertain AASHTO LRFD rating factors, developed a detailed rating report for review by both public and private entities, supervised the bridge crossing during each SPMT transport and performed pre/post bridge inspections for each SPMT transport.  The in-depth structural analysis and bridge modelling undertaken by WAE proved that acceptable rating factors could be achieved from the existing bridge.  This then allowed each reactor to be transported by standardized SPMT v. a more complicated and time-consuming jack-n-slide method.  It is estimated that this resulted in a $750,000 savings to the project.

WAE would especially like to thank Mammoet (Eric Molenda and Nathan Overell) and all the public and private agencies that made this a very successful and safe transport.  The attention to detail and professionalism shown by all made this a truly a TEAM effort.

Milwaukee Street Bridge over Rock River

By

The Milwaukee Street Bridge over the Rock River in Janesville, WI opened last week.  Westbrook was responsible for construction administration and engineering.  The new bridge is a four-span bridge with decorative arches, parapets, and lighting.  This project replaced a four-span concrete arch bridge that was built in 1913/14 that had outlived its design life and had become structurally deficient.  That bridge in turn had replaced a timber structure that burned down in 1913.  Remnants of past structures were encountered throughout the project.  The project team also worked through multiple floods and the current pandemic.

CTH M – Washington County

bridgeCTH M bridge construction inspection, in the Town of Trenton within Washington County, Wisconsin, continues to move along quickly despite the cold and snow in February. The old bridge deck and piers are demolished. The piles are driven and both new piers are poured. In the coming weeks, the abutments will be poured with the deck to follow. The project is running on schedule and under budget and is expected to be completed summer 2020. Photo is courtesy of Washington County’s drone.
