TRANSMITTAL LETTER FOR BOARD MEETING OF APRIL 4, 2019
COMMITTEE ON ENGINEERING
Mr. Brian A. Perkovich, Executive Director
Title
Authority to make final payment to the Illinois State Toll Highway Authority in an amount not to exceed $127,546.91, for relocation of a segment of the O’Hare-Egan Solids Pipeline. Account 401-50000-645700
Body
Dear Sir:
The Illinois State Toll Highway Authority (ISTHA) widened the Jane Addams Tollway (I-90) and reconstructed the interchange at Elmhurst Road. To ensure that there were no conflicts with the new roads and facilities and to ensure District access, approximately 1,000 feet of the O’Hare-Egan Solids Pipeline were moved and reconstructed. At the September 4, 2014 Board Meeting, the Board granted authority to enter into an Intergovernmental Agreement (IGA) with ISTHA. The IGA, dated September 14, 2014, authorized ISTHA to remove spoil at the Majewski Reservoir site for use on its O’Hare West Bypass project, and required the District to reimburse ISTHA for the actual costs to relocate a segment of the solids pipeline since it was within the existing ISTHA right-of-way.
ISTHA designed and constructed the sludge line relocation in conjunction with its roadway construction. Design and construction was based on District standards, and the District approved the final plans, specifications, and bid prices. Furthermore, the District monitored construction to ensure District standards were met.
When the ISTHA awarded the work, the final cost for relocation of the solids pipeline, including engineering and construction, totaled $330,252.47. Construction of the ISTHA contacts has now been completed, and the District has made two payments totaling $330,252.47. ISTHA has requested an additional $127,546.91 as a final payment for cost above the original bid price.
The Engineering Department has reviewed the additional costs and finds them acceptable. These costs include:
• Increased length of steel casing with installation to protect the sludge line from a ramp reconfiguration approved by ISTHA after the contract letting.
• Costs for removal of a below-grade thrust block that were larger than anticipated. ISTHA originally denied the cost but paid it after resolution through ISTHA’s claim process.
• Spoil and excavated material removal and disposal beyond what was included in the original contract.
• Costs associated with installation of casing pipe and concrete collar to better protect the solids pipeline in the future.
Based on the foregoing, it is requested that the Board of Commissioners grant authority to make a payment, by direct voucher, in an amount not to exceed $127,546.91 to ISTHA as final payment for the reconstruction of a segment of the District’s sludge line.
Funds are available in account 401-50000-645700.
Requested, Catherine A. O’Connor, Director of Engineering, WSS:KMF
