811 Chicago is a twenty-four (24) hour service network system established to prevent
contractors and private citizens from hitting any existing utility line(s) when digging.
This agency provides a free One Call service to private contractors and homeowners
within the City of Chicago's Corporate Limits. This system notifies all utilities of
impending excavations. All non-emergency penetration/excavation requires a forty-eight
(48) hour minimum prior notice (excluding Saturdays, Sundays, and holidays) to 811 Chicago
This important service helps to ensure public safety and protects utility facilities both in the public way and on private property. Those interested in digging in Chicago must first call 811 Chicago two (2) working days (48 hours) before digging. The forty-eight hour waiting period mandated by The Illinois Underground Utility Facilities Damage Prevention Act (220 ILCS 50/1 et seq) Section 10, allows the utility companies time to mark the ground where their facilities exist below the surface.
As the City of Chicago and State of Illinois have enacted measures to mitigate the spread of COVID-19, Chicago Department of Transportation (CDOT), Division of Infrastructure Management (DIM) reminds its stakeholders—including utility providers, construction companies, locators, and project managers—that public way management is an essential function. As such, DIM intends to operate its core work groups—OUC, Permitting, 811 Chicago, and Public Way Enforcement—in accordance with measures proposed by public health officials. To ensure that work in the public right of way proceeds in an effective, efficient, and safe manner, DIM will continue to require companies planning to excavate in the public right of way to obtain a permit and a dig ticket from CDOT prior to starting work. However, to accommodate COVID-19 mitigation measures, DIM asks users to adhere to the following procedures.
By adhering to the guidelines above, companies working in the public way should be able to continue their work without overly taxing the resources of other public way stakeholders. CDOT will notify stakeholders if its services are further affected by COVID-19.
