Structural Engineering Services for 7 Structures

Kane County, IL

Bowman provided Phase I and Phase II engineering design services for the repair and maintenance of seven separate structures. Work included the determination of appropriate repair and maintenance activities for each structure based on recent Bridge Condition Reports, discussions with KDOT staff, and other improvements determined during the Phase II engineering. Bowman staff also prepared Environmental Survey Request (ESR) exhibits for the bridges to be reconditioned.

Projects included the development of Maintenance of Traffic plans, acquisition of all permits from regulatory agencies as necessitated by the work, and development of Plans, Specifications, and Estimate (PS&E) documents. Two bridge locations will utilize modifications of existing grouted key-ways between precast deck beam sections to ultra-high performance concrete (UHPC) key-ways and one structure will use UHPC overlay. These rehabilitation techniques will be used for the first time in the State of Illinois and are being promoted by FHWA as long lasting repairs.
