E.,Director of Engineering& Infrastructure <br /> Matthew C. Newell,P. E., City Engineer�yvt/� <br /> SUBJECT: Agreement with Homer L. Chastain <br /> Bridge Inspections <br /> SUMMARY RECOMMENDATION: <br /> Staff recommends that the City Council approve the attached resolution authorizing an <br /> agreement with Homer L. Chastain & Associates, LLP, (Chastain) to provide a structural <br /> inspection for five precast concrete deck beam bridges in the City. The proposed agreement is <br /> for a fee not to exceed $7,965.00. <br /> BACKGROUND: <br /> Earlier this year, The Illinois Department of Transportation notified governmental entities <br /> throughout the State that problems have been detected in precast deck beam bridges. These <br /> bridges are strengthened with cables that have been placed under tension within the beams in <br /> order to provide support for the structure. <br /> � <br /> It has been found in other areas of the State that the tensioned cables within these bridges can <br /> deteriorate to the point of failure while showing few outward signs. IDOT has advised an in- � <br /> depth inspection of these bridges. The City currently maintains five of the precast deck beam <br /> bridges in question. <br /> The five bridges to be inspected are: Center Street over Stevens Creek; Hickory Point Road over <br /> Stevens Creek; Hill Avenue over Spring Creek; MacArthur Road Bridge over Stevens Creek; <br /> and South Shores Drive over Sand Creek. <br /> Chastain has provided the City with a great deal of structural expertise over the years, especially <br /> in regard to City bridges. Staff recommends Chastain to perform an in-depth review of the deck <br /> beam bridges in question. <br />
