NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF ELGIN, ILLINOIS, that Larry L. Rice, City Manager, be and is hereby authorized and directed to execute Change Order No. 3, a copy of which is attached hereto and made a part hereof by reference. s/ George VanDeVoorde George VanDeVoorde, Mayor Presented: December 16, 1992 Adopted: December 16, 1992 Omnibus Vote: Yeas 7 Nays 0 Recorded: Attest: s/ Dolonna Mecum Dolonna Mecum, City Clerk • ELGIN, ILLINOIS BIG TIMBER/TYLER CREEK INTERCEPTOR CHANGE ORDER NO. 3 SCOPE: This Change Order #3 covers additional changes in the scope of work at the Big Timber/Tyler Creek Interceptor that were not reasonably foreseeable at the time the contract was signed and are in the best interest of the City. The item covered in this change order is for additional cost for sanitary sewer bore and jack. This contract for construction is with Szabo Contracting, Elmhurst, Illinois. REASON FOR CHANGE: The project was originally designed and bid with the installation of the 36-inch diameter sewer installed by open cut method across Big Timber Road just west of Lyle Avenue. After the project was bid, the City of Elgin decided that it would be in their best interest to bore and jack the interceptor sewer under Big Timber Road. This would allow Big Timber Road to remain open to traffic while construction is ongoing, thus minimizing commuter inconvenience. After the bore and jack operations were started, utilizing a 48-inch diameter casing, the contractor encountered soil conditions beneath the road that prevented the casing from remaining at the proper elevation. The soil conditions encountered were not discernible from the contract documents or site inspection. It was decided that in order to ensure the pipe could be installed at the correct elevation, a larger diameter casing was needed. The installation would also have to be performed using a push and hand mine procedure instead of bore and jack. This will result in a net addition to the contract. SUMMARY OF CHANGES IN CONTRACT AMOUNT: The amount of the contract will be revised as follows: Item 1. Add 100 lineal feet of 36-inch diameter sanitary sewer crossing (push and hand mine) including 60-inch diameter casing at $395/l .f. Total Add = $39,500 TOTAL NET ADDITIONAL COST = $39,500.00 The original contract with Szabo Contracting was for $1,769,562.50 (one million, seven hundred sixty-nine thousand, five hundred sixty-two and 50/100 dollars) . Previous change orders amounted to $114,236.35 (one hundred fourteen thousand, two hundred thirty-six and 35/100 dollars) . With this change order amounting to $39,500.00 (thirty-nine thousand, five hundred and no/100 dollars), the total contract will be for $1,923,298.85 (one million, nine hundred twenty-three thousand, two hundred ninety-eight and 85/100 dollars) .

BACKGROUND: The work on the crossing of Big Timber has come to a stop based on the materials encountered at Big Timber and Lyle intersection. The sewer has been extended to that point and the contractor has been trying to bore under Big Timber Road. The ground conditions found at this location are sand, silt and water. This type of material has made the augering of the casing that will hold the pipe impossible. The contractor has requested that he be allowed to jack and mine this crossing. To jack and mine it will be necessary to install a 60" casing which can be jacked under the road while the excavation for the new casing is done by hand from inside the casing. Because this method is necessary the cost of the crossing of Big Timber Road will be substantially increased and the length of time to complete the job will be extended into December. A copy of correspondence from the contractor is attached for your consideration. The Change Order #3 and recommendation letter from the Engineer will be provided prior to the Committee of the Whole meeting. FINANCIAL IMPACT: The additional cost for the jacking and mining of the crossing of Big Timber Road will increase the contract by approximately $39,500 ( 100 feet @ $395 per foot) . The current cost of the contract is $1,883,798.85. The proposed new cost would be $1,923,298. 80. A copy of the change order will be provided at the time of the Council meeting for your review and consideration. MAYOR AND MEMBERS OF THE CITY COUNCIL November 5, 1992 PAGE 2 RECOMMENDATION: It is recommended that the City Council direct the City Manager and City Clerk to execute Change Order No. 3 for the Big Timber/Tyler Creek Interceptor Sewer contract with Szabo Contracting in the amount of $39,500. at _ ALA A Lar .
