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. 1, a copy of which is attached hereto and made a part hereof by reference. s/ George VanDeVoorde George VanDeVoorde, Mayor Presented: August 12, 1992 Adopted: August 12, 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. 1 SCOPE:. This Change Order #1 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 interests of the City. Items covered in this change order are for: 1) temporary bituminous surface replacement, 2) sanitary sewer bore and jack, and 3) sanitary sewer open cut with granular trench backfill . This contract for construction is with Szabo Contracting, Elmhurst, Illinois. REASONS FOR CHANGE: • 1. The project was originally designed and bid with the contractor responsible for replacing the existing pavement, disturbed during installation of the interceptor sanitary sewer, with a new bituminous pavement consisting of aggregate base, prime coat, binder course, and surface course. After design and bid of this project, the City of Elgin proceeded with separate design and bid of road improvements on Big Timber Road from Randall Road to North McLean Boulevard. It was determined that it was in the best interest of the City of Elgin not to install permanent paving as part of this contract that was scheduled to be replaced later. It was further determined that the installation of a two-inch thick bituminous surface course would allow public use of the roadway until the proposed road improvements were completed. This will result in a net deduct from the contract. 2. The project was originally designed and bid with the installation of the 36-inch diameter sewer installed by open cut methods 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 will allow Big Timber Road to remain open to traffic while construction is ongoing, thus minimizing commuter inconvenience. This will result in a net addition to the contract. 3. The project was originally designed and bid along a sanitary sewer easement on the north side of Big Timber Road. Realignment was necessary due to placement of a new water main in the path of the new sanitary sewer. The realignment placed the piping beneath a portion of the NIGAS parking lot. This installation required granular backfill in lieu of earth backfill . A change order for this item is necessary because there was no unit price originally bid for the installation at the depth encountered in this location. 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 2,478 sy. of temporary surface replacement, bituminous concrete (Class I) at $14/sy. Total Add = $34,692.00 Deduct 2,556 sy of permanent surface replacement, bituminous concrete (Class I) at $23/sy. (Bid Item 31) . Deduct = $58,788.00 Total Net Deduct = $24,096.00 2.

As the work was finished in Big Timber Road a concrete patch was to be installed in the roadway cut and then asphalted. Based on the extended period of time it took to get out of Big Timber Road, it was decided to delete the concrete repairs and place 2" of asphalt in the roadway to get the road open. The delays to the project were because of the contaminated soils the contractor found in the area of the Amoco station at Big Timber and McLean. The permanent repair to Big Timber Road will be accomplished by adding the concrete repair by change order to the existing contract with Palumbo, Inc. , the contractor doing the Big Timber and McLean widening projects . The cost to change from a permanent concrete repair to a two inch asphalt temporary repair results in a credit to the City of Elgin of $24,096 .00 . The contract for the interceptor sewer was bid and awarded to install the new 36" sewer in an open cut across Big Timber Road west of Lyle Avenue. Upon review of the soils and the disruptions to traffic should the roadway be closed it was decided to request that the contractor jack and auger under Big Timber at that location. The public meetings held with residents emphasised the augering under Big Timber in lieu of open cutting. r Mayor and Members of the City Council July 16 , 1992 Page 2 The cost to auger under Big Timber Road in lieu of open cutting will result in an additional cost to the City of $60,843 .50 . With the installation of the interceptor in the easements along the north side of Big Timber Road it was necessary to add trench backfill through the area of the N. I . Gas property. This was necessary to retain the integrity of their driveway and parking lot. The cost to substitute trench backfill in lieu of original material will result in an additional cost to the City of $7, 320. 00. A detailed letter from Clark Dietz, Inc. , consultant for this project, is attached for your consideration. risk FINANCIAL IMPACT: The additional cost for Change Order No. 1 is $44,067 .50. The cost adjustment is explained further explained in the attached letter from Clark Dietz . There are adequate funds available in the 1991 G.O. Bond project fund to pay for this additional work (391-997-9920) RECOMMENDATION: It is recommended that the City Council authorize City Manager to execute Change Order No. 1 to the contract with Szabo Contracting for the Big Timber/Tyler Creek Interceptor Sewer in the amount of $44, 067 .50 . A copy of the change order is attached for your consideration. Larr . Rice, ty anager Attachments üíE 1.7, INC. 1L1 31J4ld41:111F'11GIHHta-, P.0.9 (111.4 C D 1 CLARK DIETZ, INC. July 13, 1992 Mr. Ralph Ridley Engineering Supervisor City of Elgin 150 Dexter Court Elgin, IL 60120-5555 Re: Big Timber/Tyler Creek Interceptor Dear Mr. Ridley: In regard to the above referenced project, we have requested and received quotes (see attached) from Szabo Contracting for the following items: 1 . Temporary Bituminous Pavement. This item addresses installation of a two-inch thick bituminous surface course as a temporary roadway in lieu of the permanent pavement as bid. The upcoming roadway construction project will be providing a new pavement and it was determined that there was no need to install permanent pavement at this time on this contract, only to have it removed at a later date. The approximate cost of the permanent pavement is $58,788. The approximate cost of the temporary pavement is $34,692. Therefore, the net deduct of this item is approximately $24,096. 2. Big Timber Bore and Jack. This item addresses installation of the 36-inch diameter sewer by bore and jack method instead of open cut. Discussions with City personnel revealed that since Big Timber Road is a major access road, open cut installation of the sewer pipe would create a traffic nightmare. This discussion and decision was made after the project was bid and awarded. The approximate cost of the bore and jack installation is $82,500. By installing the pipe by bore and jack method, an equivalent length of open cut pipe installation will be deducted. The approximate cost deduct for this item is $21,127.50. Bituminous paving for Big Timber Road would also not be required resulting in a deduct of approximately $529.00. Therefore, the net addition for this item is approximately $60,843.50. 3. This item addresses the addition of a unit price line item for pipe installed beneath the NIGAS parking lot with BFM #4. The approximate cost is $16,560_ An equivalent amount of BFM #2 pipe installation will be deducted. The approximate cost deduct for this item is $9,240. Therefore, the net addition for this item is approximately $7,320. r Clark D+etz_, Inc 1817 S Neil Suit? 100 T'? box 67+1 l:narnpAign.
