Title
135th Street Watermain Relocation - Engineering Design Services
History
The Illinois Department of Transportation (IDOT) in conjunction with McDonough Associates Inc. (MAI) of Chicago, Illinois, continues to finalize the engineering for the LaGrange Road Corridor reconstruction project. As final engineering progressed and underground utility locations were better known, additional utility conflicts were identified due to revised grade changes and storm sewer installation. Because this is a state-owned right of way (ROW), any utility within the right of way found to be in conflict with planned state work is required to relocate at their own expense.
IDOT’s proposed LaGrange Road improvements include roadway widening and a drainage ditch on the south side of 135th Street. The village’s 135th Street watermain was identified to be in conflict with these improvements. As a result, the Village watermain must be relocated. All valve vaults and fire hydrants will be adjusted or relocated to match the proposed improvements.
In February 2010, the Village Board approved a contract with MAI to provide engineering services for watermain relocation and replacement along LaGrange Road for a cost not to exceed $115,000 ($98,000 plus $17,000 contingency). As IDOT engineering evolved, numerous changes to the watermain engineering were required. To offset these costs, staff requests to release the contingency funds.
On April 23, 2012, MAI submitted a proposal to the Village for professional engineering design services for the additional work required for the 135th Street watermain relocation in the amount of $18,000.
On May 21, 2012, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
Financial Impact
Sufficient funds are available within line item #031-6002-470500 for this work.
