Title
156th Street Extension - LaGrange Road to Ravinia Avenue - Addendum to Contract with Smith Engineering Consultants
History
The Village engaged Smith Engineering Consultants Inc. (SEC) of New Lenox, Illinois, to provide professional engineering services for the extension of 156th Street. Presently, engineering and bid specifications are being finalized along with the cost sharing agreements with the adjacent property owners.
We have requested SEC to submit a proposal for Construction Layout Services and Part-time Construction Observation. Additionally, as a result of IDOT comments and Village requested scope changes, minor plan changes are also included. IDOT requested survey and plan sheet changes are required for the permanent traffic signal at LaGrange Road. Because of the timing of projects, the upcoming Ravinia Avenue reconstruction will incorporate the necessary improvements for the 156th Street intersection.
SEC has submitted an addendum for these additional services in the amount of $65,898.
On July 13, 2009, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
Financial Impact
The Fiscal Year 2008/2009 Capital Improvement Budget has a Board approved line item (054-0000-499.71-25) for the 156th Street Extension Project to cover the cost of this work. We will increase SEC Purchase Order Number 032785 for an amount not to exceed $70,000 ($65,898 plus $4,102 contingency).

(SEC) of New Lenox, Illinois, addendum for additional engineering services, construction layout and construction observation for the extension of 156th Street from LaGrange Road to Ravinia Avenue for an amount not to exceed $70,000 ($65,898 plus $4,102 contingency);
And
Approve authorizing the Village Manager to execute the addendum.
