Title
Wolf Road Ditch Improvements at 139th Street, Design Engineering Services, Contract Amendment, Supplement #2
History
In 2023, the Village Board approved a professional engineering services agreement with Christopher B. Burke Engineering, Ltd. (CBBEL) to improve the drainage on the east side of Wolf Road near 139th Street. The scope of the original engineering proposal included the development of a drainage ditch regrading plan as well as the performance of a culvert analysis to ensure the existing culvert crossing on Wolf Road had adequate stormwater flow capacity. The tasks were completed, but as the Village's McGinnis Slough Multi-Use Path project developed, it was determined that there would be a multi-use path constructed along the east side of Wolf Road as part of the McGinnis Slough project. The multi-use path will require a closed drainage system; therefore, the ditch regrading plans must be replaced with storm sewer plans. The first supplement was for CBBEL to complete the engineering design and prepare the bid package for storm sewer improvements along the east side of Wolf Road near the 139th Street intersection. While that design was completed, the estimated cost of construction far exceeded the remaining amount of funding in the Cook County intergovernmental agreement. This supplement is to repackage the contract plans as a culvert replacement project. The rest of the improvements will be packaged with the McGinnis Slough project.
Financial Impact
The fee for additional design services provided in the proposed Supplement #2 total $4,950.00. There is sufficient funding for the supplement in the approved FY2026 Budget.
