  • Disciplines: Bridge Diving Inspections, Scour Erosion Inspections, Fathometer Surveys

Bridge Diving Inspections & Fathometer Surveys. NBIS bridge diving and scour erosion inspections, including fathometric/scour evaluation of bridges spanning waterways.

Since 1991 through present day, the firm has performed bridge diving inspections on a total of 7,000 substructure units (SSU) encompassing 2,000 bridges spanning waterways, and fathometer surveys on an additional 950 bridges situated over water for the New York State Department of Transportation. The work was performed in all eleven (11) regions of the state.

To date, BOSWELL has been awarded twenty (20) consecutive term agreements for this type of work (as a prime consultant) and is the only consulting engineering firm, acting in the capacity of prime consultant, to have ever been issued concurrent, overlapping bridge diving inspection contracts by the NYSDOT. This has happened four (4) times and first occurred in 1997 when the NYSDOT Western and Southern Agreements were executed concurrently by BUE, again from 1998 through 2000 when the NYSDOT Southern and Eastern Agreements overlapped, and again in 2003 and 2004 when the NYSDOT Western and Southern Agreements overlapped.
