Last October NEW Cooperative, Inc began construction of their new marine shipping facility in Blencoe, IA with the installation of mooring pipe piles by Massman Construction Co. The past few months NEW Cooperative has also been making progress on the landside construction activities involving installation of mechanical items and construction of the new fertilizer storage building. We would like to thank NEW Coop for choosing Westbrook to provide site civil, marine, and landside structural engineering services for this facility.
Granite Construction has contracted Westbrook for the inspection of the falsework required for the construction of the Cline Avenue Bridge in East Chicago, IN. The falsework towers are constructed from steel pre-fabricated modules that are assembled together at each concrete pier of the bridge. The falsework towers help to support the eccentric loads imposed by the placement of the precast box girders segments as the Cline Avenue Bridge is built out from the pier. The proper assembly of the falsework tower is crucial to support the bridge dead loads during the various construction stages and for the safety of the construction crew. The projected completion date for this project is the end of 2020.

This project is a new agricultural marine shipping facility, which will be located along the Missouri River (rm 680.75) in Monona County, Iowa near the town of Blencoe. The proposed Ag shipping facility will involve a barge unloading area for dry fertilizer, roadway salt, and roadway aggregates (gravel & stone). These materials will be unloaded from product barges by the use of a material handler with a clamshell bucket sitting on a platform barge. Materials will be placed into a hopper sitting on the platform barge and then conveyed to the land side storage areas. The dry fertilizer products shall be conveyed to a building enclosure. Roadway aggregate and roadway salt shall be conveyed to radial tele-stacker conveyor to be stock piled. The empty product barges will then be cleaned and positioned downstream breasting against another platform barge, which will be used for loading the product barges with soybean or corn. The loading area will use a combination of belt conveyors and a radial tele-stacker conveyor to convey material to be load to the product barges and then transported down the Missouri River. The proposed Ag shipping facility will have roadways for semi-truck access to each of the above described unloading and loading areas of the site.
Westbrook Associated Engineers provided the following engineering services for this project:
- Agency Coordination & Permitting – coordination with US Army Corps of Engineers, Iowa DNR & Monona County regarding work within the Missouri river which included a Hydrologic & Hydraulic Analysis (H&H) to be included with “Joint Application” submitted to the USACOE and IDNR. Westbrook also prepared Storm Water Pollution Prevention Plan (SWPPP) including design of all associated stormwater devices to meet state and federal stormwater quality and quantity requirements for this new site development project.
- Design Phase Administrative Services – coordination with geotechnical, bathymetric survey, landside survey, building contractors, mechanical equipment suppliers, preliminary coordination with various construction related activities involving site grading, concrete foundations, structural steel, etc.
- Structural Analysis & Design – barge mooring pipe piles, modifications to both platform barges, access ramp to platform barges, modifications to used belt conveyor truss’s for increase span lengths, access walkways to barge mooring pipe piles.
- Structural Foundation Design – access ramp to platform barge, belt conveyors, fertilizer building, access walkways to barge mooring pipe piles
- Site Development – grading plan and details for loading / unloading truck traffic and design for site drainage and all stormwater devices
- Construction Phase Administrative Service – RFI’s, shop drawing review, material cert’s, on-site inspections and construction documentation control.

Westbrook 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.
When 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.
