Owner:  WI D.O.T.
Prime Contractor: Vista Design & ConstructionContract
Value:  $766,085
Project Timeline:  Completed by November 2008

Scope:

Vista demolished an existing 3-span structure and replaced it with a new 4-span structure.

Services:

The project consisted of site clearing, demolition and removal over a waterway, piling, temporary sheeting & cofferdams, construction of new piers and structure, backfilling, rip rap and erosion control, and finishing the roadway.

 Features & Challenges:

  • One of the main challenges was to construct the piers for the structures within the waterway.  Cofferdams were constructed and pumped down around the piers in order to construct the new structure.  The other challenge was to contain all debris from the old structure, and prevent from any pieces falling into the waterway.  A barge with a plywood surface was used to catch the falling debris.

 Resolution:

All services were completed on time and within budget to the satisfaction of the Owner.
