April 3, 1989 Memorandum To: From: Subject: Alan D. Ratliff, City Manager Frank Trando, Deputy City Manager/Finance Director~ Change Order #2 to the Denton Tap CI? Change order #2 is in the amount of $52,081.27. The bulk of the change order will be absorbed by ABQ Development in the amount of approximately $26,594.74 and Univest will contribute $8,679.63. The City's portion of this change order will be $16,806.90. This item was not a budgeted item for the West side turn out at the intersection of Denton Tap and Parkway Boulevard. The $16,806.90 will have to come out of the contingency funds that were originally budgeted. It would therefore be incorrect to say that this item was budgeted, but, there are sufficient funds for this project included in the total amount budgeted. I believe that Russell Doyle is in the process of obtaining letters, of intent from both ABQ and Univest stating that they will pay their pro-rata share of the change order. FT/lr DENTNTAP~003 April 3, 1989 MEMORANDUM TO: FROM: RE: Alan D. Ratliff, Ci%y Manager R. Doy/~~., City Engineer Russell REQUESTS FOR MEDIAN CUTS AND LEFT TURN LANES ON DENTON TAP ROAD - CIP - SANDY LAKE ROAD TO DENTON CREEK (Memos of 2-6 & 2-21-89) In response to requests from property owners along Denton Tap Road, we have prepared a change order for installing both median openings and left turn lanes at the total expense of those requesting the work, including the construction costs, engineering, testing and inspection. Also included in this change order is the work needed to connect Parkway Boulevard West with Denton Tap Road ($16,806.90). The summary of costs and how they will be shared between ABQ Development Company ($29,254.21), and Univest Development Company ($9,547.60), the property owners, is attached. We have requested commitment letters from these two property owners who have committed to submit their funds within five (5) working days of the approval of this change order by the City Council. This action will accomodate the requests of these two property owners, and in no way obligates the City of Coppell to limit land use or traffic planning around these requested median openings. Having the City's Contractor do this work now, provides a most efficient and cost effective way of getting this work done with the C.I.P. Project, and not have to interrupt and detour traffic at a later date, when this six (6) lane thoroughfare is open to traffic. The location of the median openings and left turn lanes are depicted in the attached drawings, and are located as follows: Station 178 + 17.77 (Median Opening Part of Project Design) Location of the High School construction Site Haul Road, identified as Lot 2 of the Coppell High School Addition Plat, and the location of Coppell Plaza Drive, the main access for the Coppell Health Care Canter. Station 182 + 44 (New Opening) Unidentified location just north of an existing drive on the west side of Denton Tap Road. Station 186 + 98 (New Opening) Location of existing drive just across from Town Center on the west side of Denton Tap Road. Station 19§ + 28 - A desired opti2u~ location, selected Dy AB0 (New Opening) Develop~nt for their properties on both sides of Denton Tap Road, north of Parkway Boulevard. Please note that the total amount f6r this item, $52,081.27, on the agenda request sheet, is a construction figure only and is arrived at by adding $35,274.37 (total construction costs to be r~ceived from ABQ and Univest), and $16,806.90 (the construction costs for connecting Parkway Boulevard West Extension), for a total construction cost of $47,773.30. Also, please note that the figure "Amount Over Budget", or $40,207.73 on the a§mnda request sheet is not solely relat ~d to this change order, but is related to the project being previously u Attached is Ginn, Inc.'s recommendation memo.

March 29, 1989 Mr. Russell R. Doyle, P.E. City Engineer city of Coppell P.O. Box 478 Coppell, Texas 75019 Re: CONSULTING ENGINEERS Denton Tap Road Improvements from Sandy Lake Road To Denton Creek, Change Order No. 2 - Revised. Dear Mr. Doyle: We are transmitting herewith six (6) copies of Change Order No. 2 (Revised) which has been recommended by the Engineer and approved by the Contractor. We recommend that you place this Change Order No. 2 on the agenda of the April 11, 1989 city Council meeting for their approval. We are also enclosing 10 exhibits for the City Council packets, as requested, showing the location of the median openings and left turn lanes covered by Change Order No. 2. As you recall, we had previously prepared Change Order No. 2 for the same items as those included herein, but the Contractor, after having the proposed Change Order in his possession for a period ~of about one month, elected not to approve the Change Order for the reasons stated in his February 27, 1989 letter, copy attached. We subsequently requested that the item be removed from the February 28, 1989 city Council meeting agenda. After reviewing both the Contractor's request for revision of the Change Order, and his Contract with the City of Coppell, we have determined that he is within his rights under the Contract to request pricing other than the Contract Unit Prices for work added to the Contract. The basis of his claim is that this is new work being added to the scope of work of the Contract, as opposed to an error in estimated quantities, which would have been covered by the existing Contract Unit Prices provided the error did not constitute more than a 20% deviance in the bid quantities for a major item. We have also determined that his proposed price for the "hand work" is reasonable for this type of work. In fairness to all parties concerned, we have revised Change Order No. 2 to allow the Contractor to perform the required "hand work" placements of 8"-3000 psi reinforced concrete for the subject median openings and left turn lanes at the new unit price of $ 16.68 per Square Yard, as measured in place. Any of the concrete placements for the subject median openings and left turn lanes which are done by slip-form methods will be paid for at the existing Contract Unit Price of $ 13.68 per Square Yard. 17103 Preston Road · Suite 100 · LB 118 · Dallas, Texas 75248 · Phone 214/248-4900 The total costs shown in the attached Cost Estimates and Summary and Distribution of Construction Costs are based on the $ 16.68 per S.Y. unit price. The new costs reflect an increase of $4,307.97, or 14%, over the initial estimated construction cost for the subject median openings and left turn lanes. ABQ Development's and Univest Development's construction costs increased by the same 14% resulting in increases in construction costs of $3,226.14 add $1,081.83 respectively. The costs for Engineering, Testing and Inspection associated with the subject median openings and left turn lanes increased by 14% also. As you had requested, we have informed both ABQ Development and Univest Development of the situation. We recommend that approval of this Change order No. 2 by the city Council be contingent upon the upon receipt of the financial commitments of ABQ and Univest as originally agreed upon. Please call me if you have any questions. Sincerely, / JOhn C. Ka~lsruher, P.E. Project Engineer attachments cc: H. Wayne Ginn, P.E.
