Title
Tinley Creek Improvement Project - Additional Engineering Services - Board Approval
History
On May 15, 2006, the Village Board approved the proposal from Christopher B. Burke Engineering Ltd. (CBBEL) of Rosemont, Illinois, totaling $58,500 for the Tinley Creek and Midlothian Creek (Phase II and Phase III) engineering. Midway through the engineering, it became apparent that the construction cost would require the project to be bid as two separate projects for budget purposes. Village staff directed CBBEL to prepare two separate engineering plans. As a result, the number of plan pages increased from the proposed twenty-three (23) pages up to fifty-five (55) pages. CBBEL also assisted in two bidding periods including answering contractor questions, issuing addendums and attending meetings as needed. Additionally, the Illinois Department of Natural Resources - Office of Water Resources unexpectedly imposed additional requirements for individual permits at five (5) of the culvert crossings in Phase II and the Creek reshaping in Phase III. This has resulted in CBBEL incurring additional costs above the estimated fee.
Both Tinley Creek and Midlothian Creek Phase II and Tinley Creek Phase III have been successfully bid. Phase II is 95% done with only restoration left to complete. Phase III is just underway at about 20% completion. As part of each project, CBBEL is performing construction oversight services for the Village. Phase II construction services have an expected cost savings of $15,500 due to the ease in which the construction was completed.
Based on the additional services provided by CBBEL for the engineering phase of the project, staff recommends the Phase II construction services cost savings of $15,500 be used as reimbursement.
On May 11, 2009, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
