UTILITY LOCATION

The Contractor must exercise extreme caution while working around existing utilities. The Contractor shall notify JULIE (1-800-892-0123), a minimum of 48 hours before commencing construction for utility locations within the scope of the project. It is recommended that the Contractor conduct a joint utility meet. It is the responsibility of the Contractor to contact all agencies who may or may not be part of the JULIE system to verify the location of their facilities.

The Village does not guarantee the accuracy or completeness of this existing utility information. The Contractor shall make their own investigation to determine the existence, nature, and location of all utility lines and appurtenances within the limits of the improvement. The Contractor shall locate all utilities far enough in advance to avoid all conflicts in grade separation between existing utilities and the proposed improvements. If the Contractor encounters a conflict between the proposed improvements and existing utility that was not located in advance by the Contractor, then the Contractor shall, at no cost to the Village, relocate the proposed improvements and/or the utility to avoid the conflict.

The Contractor will be required to cooperate with all utility companies involved in connection with the removal, temporary relocation, reconstruction, or abandonment by these companies of any and all services or facilities owned or operated by them within the limits of this improvement.

Before doing any work, which will damage, disturb, or leave unsupported or unprotected utility lines, the Contractor shall notify the respective Owner. The Owner will make all arrangements for relocating, adjusting, or otherwise maintaining or abandoning service on lines that fall within the limits of the proposed construction without cost to the Contractor. This includes the removal of all cables, manhole covers, and other appurtenances which the Owner desires to salvage. After such arrangements have been made, the Contractor will proceed with the work as directed by the Engineer. All utility lines and appurtenances which are abandoned by the Owner shall be removed and disposed of by the Contractor.

No extra compensation will be allowed to the Contractor for any expense incurred by complying with these requirements or because of delays, inconvenience, or interruptions in their work resulting from the failure of any utility company to remove, relocate, reconstruct, or abandon their services. The Contractor shall be responsible for prompt and timely removal, relocation, reconstruction, or abandonment of their facilities by all utility companies involved, and the coordination of their own work with that of these companies to end that work on this improvement is not delayed because of necessary changes in the existing utilities, public or private.
