We’ve partnered with a utility company to provide ongoing bridge inspection and maintenance for 55 bridges across the Chicagoland area. The structures range from single-span bridges in rural areas to multi-span bridges over Chicago streets. Many of the bridges are old railroad structures that are up to 110 years old. All bridges are inspected at a 24-month interval, using National Bridge Inspection Standards (NBIS) inspection forms when appropriate. When rehabilitative needs are discovered, we assist the utility company in determining where priorities lie, providing design services for anything from minor bridge repairs, to replacement of a bridge with a pipe culvert, to a full redesign of a replacement bridge structure. We also provide permitting services and construction quality assurance services for many of the bridges that require rehabilitative work.
