IDOT Taps TWM Expertise for Statewide Structural Engineering

April 2012 – The Illinois Department of Transportation (IDOT) has selected TWM for a statewide structural engineering contract.  The work for the Bureau of Bridges and Structures may include routine National Bridge Inspection Standards (NBIS) inspections; bridge damage inspection and preparation of damage repair plans; preparation of Bridge Condition Reports and plans for programmed bridge repair, rehabilitation, or replacement; and load capacity rating of existing and/or new structures.

TWM employs five structural engineers, three of whom are state certified NBIS Program Managers / Team Leaders for bridges in the National Bridge Inventory (NBI).  By federal statute, all publicly owned highway bridges are covered by the NBIS standards and must undergo routine inspections at 24- or 48-month intervals depending upon criteria established by IDOT.
