Title/Name/Summary
Tinley Creek Streambank Stabilization, Design Engineering Services, Contract Amendment #4
History
The Village and the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) have been working on the Tinley Creek Streambank Stabilization project since 2014. The engineering design effort for this project is nearly complete and construction could start in the next few months. The Village needed 57 easements from the property owners along the creek to proceed with the project. The Village has secured 53 easements, and the following four property owners have declined to accept the Village’s requests for easements.
1. 15437 Teebrook Drive
2. 8448 Teebrook Drive
3. 8430 Flamingo Circle
4. 8434 Flamingo Circle
The engineering design of the banks was completed in 2023. Since the above four property owners did not provide easements, the Village decided to eliminate these four properties from the project. This change requires redesigning the project at and around these four properties. Some of the major design changes include replacing the gabion wall section adjacent to 8455 Teebrook Drive to a soldier pile wall to allow no work to be performed on 8434 Flamingo Circle. The following is a list of additional scope of services that need to be completed to prepare design documents for bidding:
· Engineering design revisions
· Engineering plan and specification revisions
· Retaining wall design and structural plans
· Geotechnical soil borings
Financial Impact
The engineering consultant for the project, V3 Companies, Ltd., has prepared and submitted the attached proposal for their professional services. The total fee for this additional design effort is $41,500.00. The Engineering Department previously anticipated that there will be additional design efforts and sufficient funds were included in the adopted 2025 Capital Improvement Projects budget.
