Rice, City Manager SUBJECT: Northwest Interceptor Sewers Contract Amendment for Design Engineering PURPOSE: To provide the Mayor and Council with information to consider an amendment to the contract with Clark Dietz, Inc. (CDI) for Design Engineering Services on the Northwest Interceptor Sewers. elk BACKGROUND: The City Council awarded an engineering contract to CDI at their June 26, 1991 meeting for the design and inspection of two sewers in the northwest area of the City. The two projects were the Big Timber/Tyler Creek and North Randall Road Interceptor Sewers . During the last two weeks of October 1991, the center line of the Big Timber/Tyler Creek Interceptor west of the railroad spur was moved from the previously approved location on the north edge of Big Timber Road to easements north of Big Timber Road and the existing FRWRD easements . This change was required to minimize the impact of the sewer construction on traffic along Big Timber. During November 1991 the location of the center line of the Big Timber/Tyler Creek Interceptor was moved 10 foot off of the north park line along Tyler Creek at the request of Valley Creek Corporation. No additional surveying was done for the interceptor move, but extensive redesign and redrafting was required for the interceptor. The route of the North Randall Interceptor was changed due to requests by Panasonic. The new route was surveyed, redesigned and drafted. The route of the North Randall Interceptor north of I-90 was changed due to concerns of possible soil contamination along the petroleum pipe line which was detected when obtaining soil borings. The new route was surveyed, redesigned and drafted. This extra work, however, is to be expected in this type of contract and is not recommended for payment. Mayor and Members of the City Council April 22, 1993 Page 2 The revised route of the Big Timber/Tyler Creek Interceptor along the north park adjacent to Tyler Creek was again revised to the original location. The route of the North Randall Interceptor north of I-90 was also revised back to the original location. No survey was required for these revisions, but the drawings again required revisions . During February 1992, CDI was directed to modify the drawings and specifications to incorporate a bore and jack under the trees at Panasonic. This was done at the request of Panasonic so as not to remove trees or destroy the park like area along the sewer route. Also during February, the drawings and specifications for both projects were modified twice due to changes at the intersection of Big Timber Road and McLean Blvd. The 155 ' of 60" pipe and the 10 ' manhole in Big Timber Road were removed from the Big Timber/Tyler Creek Interceptor project and added to the North Randall Road Interceptor project because of concerns that the Big Timber sewer project could not be bid due to easement problems. After the changes were made, it was decided that the Big Timber project could be bid and started first, and the drawings and specifications were changed back to the original design. Additional changes in the easement of the Big Timber/Tyler Creek Interceptor between Tyler Creek and the Metra Commuter Rail required a revision to the alignment of the interceptor. To avoid the cost of again surveying this portion of the project, CDI utilized a topographic survey of the area by Burnidge and Westphal. The North Randall sewer was designed to pass through the east side of the Panasonic property in accordance with our conversations with the representatives from the organization constructing the Panasonic complex. We were still negotiating for the easement when Panasonic accepted the complex at which time we were informed by Panasonic that they would not grant the easement. Due to the problems in obtaining easements from Panasonic, the route of the interceptor was changed to provide a crossing of the Tollway at property owned by P.K. Products. In addition to the changes on the south side of the Tollway, it was necessary to make changes on the north side of the Tollway. We obtained permission to place approximately 250 feet of interceptor on emk Tollway property parallel to the right-of-way in order to avoid obtaining an additional easement on the north side of the Tollway. To avoid the cost of performing additional survey, CDI prepared the plans on the north side of the Tollway based on USGS maps and utilized survey data prepared by Burnidge and Westphal across the P.K. Products property on the south side of the Tollway. Redesign and drafting was required. 'ow Mayor and Members of the City Council April 22, 1993 Page 3 FINANCIAL IMPACT: The original engineering contract was in the amount of $314, 900 which was to cover the cost of the design and field inspection of the two sewer projects . The cost of all this additional work which was not anticipated is $41,012 .49 . After deducting the cost of the redesign North of the tollway, which the City has rejected as an extra payment item, the revised cost is $37,290 . 95 . The above amount will increase the engineering contract to $352, 190. 95. RECOMMENDATION: It is recommended that the City Council authorize the preparation of a contract amendment with Clark Dietz, Inc. for the design and inspection of the Northwest Area Interceptor Sewers in the amount of $37 ,290 . 95. f _ -7 Larry.

April 20, 1993 Mr. James Kristiansen Director of Public Works City of Elgin 150 Dexter Court Elgin, IL 60120-5555 • Re: Big Timber/Tyler Creek and North Randall Interceptors Dear Jim: In our meeting last Tuesday, you indicated that I needed to submit a request for a contract amendment that incorporates all of the additional costs that we have incurred for the interceptor projects. This letter is intended to replace our letters of June 10, 1992, November 3, 1992 and April 8, 1993. In preparing this request, we have reviewed the costs previously submitted to assure that the claimed costs are accurate and include all associated expenses. Since the previous requests did not include some of the related expenses, the amounts included in this request may vary from the previous requests. I have attached descriptions and costs associated with this request. Following is a summary of the requested contract amendment: Design Changes $ 41,012.49 Extended Contract Duration 76,170.92 Other Additional Construction Phase Costs 33.63L,67 Total S150,815.08 In an effort to see this project through completion, we have continued to work, even though we believe we have exceeded the requirements of our contract. Part of the costs included in this request were previously authorized by the City. We believe, however, we are due a contract amendment for the entire amount. Since you have withdrawn your previous authorization, it is imperative that we resolve this issue and receive a contract amendment quickly. Sincerely, Clark Dietz, Inc. (%%lc G�gGz_ Charles E.

The actual contract was signed on June 24, 1991. CDI did complete the design and submitted the documents to the City on October 16, 1991. A preliminary submittal was made to the City on August 28, 1991 as required by the contract. The Engineering Services Agreement specifically requires that the City reimburse CDI for revising previously approved Drawings and Specifications. The following Design Changes were required by the City after the completion of the Bidding Documents: Alignment Along Big Timber The original design was based on the installation of the Big Timber/Tyler Creek Interceptor within the roadway along Big Timber from the intersection at McLean to the west. This routing was determined by the City. This alignment was approved in a review of the preliminary drawings on September 3, 1991. During the last two weeks of October 1991 we revised the interceptor location to the north of the FRWRD easement along Big Timber from the railroad spur to the west. It was necessary to resurvey, redesign, prepare new drawings, and revise the specifications. Following are the costs associated with this work: Labor $5,104.59 Expenses 1.049.92 Total $6,154.52 Based on quality control review, CDI had recommended on September 19, 1992 that the sewer be moved 10 feet further into Big Timber roadway in order to reduce the construction cost associated with protecting existing utilities. Note, however, that the sewer could have been constructed as originally designed. If our recommendation had been accepted, only minor drafting work would have been required. Instead, the City decided to move the interceptor completely out of the roadway in order to minimize the impact on traffic along Big Timber. The decision was not made until the design documents were complete. Alignment Along Tyler Creek The original design along Tyler Creek was along the fence line. That alignment was based on direction by Ralph Ridley at the September 3, 1991 review meeting. It was our understanding that he had an agreement with the landowner to allow placement at that location. On November 7, 1991 the location was moved to 10 feet off of the north park line based on a revised verbal agreement between the City and the landowner. No additional survey was required.

Labor $2,308.69 Expenses 401.50 Total $2,710.19 Alignment Change At Panasonic The original design along the Panasonic property was based on direction by Ralph Ridley and the understanding that he had an agreement with the landowner. On November 7, 1991 the routing through the Panasonic property was changed at the direction of Ralph Ridley as requested by the landowner. In order to perform this work, it was necessary to perform additional survey, design and drafting. Following are the costs associated with this change. Labor $2,176.22 Expenses 247.50 Total $2,423.72 Ali t Change North of I-90 The original design'of the North Randall Interceptor to the north of 1-90 was parallel to an existing Badger petroleum pipeline. Because of concern about possible petroleum contamination of the soil, CDI was directed on November 7, 1991 to revise the routing to avoid the pipeline. In order to perform this work, it was necessary to perform additional survey, design and drafting. Following are the costs associated with this change. Labor etpprev.2,01 $3,399.70 Expenses j' 321.84 Total $3,721.54 C' Alignment Along Tyler Creek and North of I-90 The revised route of the Big Timber/Tyler Creek Interceptor along Tyler Creek was again revised to the original location. The route of the North Randall Interceptor north of I-90 was also revised back to the original location. Both of these changes were due to the failure of the City to obtain easements at the proper time. While no survey was required for these revisions, the drawings and specifications had to be changed again. Following are the costs associated with this change.

This change was required because the City had not obtained easements at the proper time. Also during February, the Drawings and Specifications were changed twice concerning the work at the intersection of Big Timber Road and McLean Blvd. Because of the changing.ea<ment situation, we were required to move parts of the work between the two projects in order to allow bidding of at least one of the two interceptors. Following are the costs associated with these changes. Labor $10,623.59 Expenses 1.694.08 filbk Total $12,313.67 Additional Revision of Alignment Along Tyler Creek Due to changes in the easement finally obtained by the City for the interceptor along Tyler Creek, the alignment was again revised. CDI utilized topographic data provided by Burnidge and Westphal to avoid the need to perform additional survey. Drafting was required. The Specifications were not changed since the project was already under construction. Following are the costs associated with this change. Labor $2,473.99 Expenses _ 74,53 Total $2,548.52 Revision of Easement At P. K. Products Due to problems in obtaining easements from Panasonic, CDI was directed to redesign the Tollway crossing to utilize an easement the City was negotiating with P. K. Products. In addition to the redesign on the south side of the Tollway, it was necessary to make changes to the design to the north of the Tollway and obtain permission from the Tollway Authority to place approximately 250 feet of interceptor on Tollway right of way in order to avoid easement problems with a landowner. To avoid the cost of resurveying, we based the plans on the north side of the Tollway on USGS maps and utilized a survey by Burnidge and Westphal across the P. K. Products property.
