BACKGROUND: City staff conducts routine bridge inspections of 28 bridges throughout the City. Bridge inspections are completed within guidelines set by the Illinois Department of Transportation(IDOT)and the Federal Highway Administration(FHWA). The routine inspections can lead to findings that require a more detailed review, structural analysis,and/or repair.While most inspections are done by City staff, sometimes a third party engineering firm is needed to perform inspections that require certain expertise or equipment.The bridges listed in the memorandum to Council in 2016 have structural concerns that benefit from being reviewed by a structural engineer from time to time. The Garfield Bridge over 22nd Street is a pin and hanger bridge which requires an ultra-sonic inspection of the pins every 4 years since they cannot be visually seen. AECOM is the only local firm that can provide these specialized services. They have good experience with this bridge and City staff has approached them to provide the ultra-sonic inspection and the regular inspection of the structure and prepare an updated design report. Engineering Services Agreement: Garfield Avenue over 22nd Street Bridge Inspection The design services are to provide a bridge condition report that will be used for the City to move forward with issuing a request for proposals to provide the design for the future rehabilitation of the structure.An in-depth inspection of the entire structure, including the special ultra-sonic test of the pin and link assemblies,will be performed.NBIS inspection documents will be filled out for submittal to the Illinois Department of Transportation. The proposed total fee is$29,972.30,which will be paid with State Motor Fuel Tax funds. PRIOR COUNCIL ACTION: June 20,2016—The City Council was given a memorandum detailing the condition and status of the City's bridges that fall within the jurisdiction of the National Bridge Inspection Standards(NBIS).
