ST8402-CS 890127 GINN, INC. January 27,/~ P.O. Box 478 Coppell, Texas 75019 Re: CONSULTING ENGINEERS Denton Tap Road Improvements from Sandy Lake Road to Denton Creek - Parkway Blvd. extension and additional Left Turn Lanes and Median Openings requested by ABQ Development and Univest Development. Dear Mr. Doyle: On the afternoon of Thursday, ~,arv 5.~ 19~J~, a meeting was held in these offices between yourself, Mrs. Daneshmand, Mr. Wayne Ginn, and myself to address the requests by ABQ Development and Univest Development for additional left turn lanes and median openings to be included in the Denton Tap Road project to serve their properties. The minutes of this meeting are attached. The end result of the meeting was the direction from yourself to proceed with preparation of a Change Order to the Contract with L. H. Lacy Co. to provide for the construction of the requested facilities, contingent upon approval by the City Council. One of the stipulations to be included for Council consideration is that the financial commitments from ABQ and Univest to pay for these additional improvements must be satisfied before the approved Change Order can ~e issued and work commenced on the subject items. ~ ~bd~/~~/%~/~ ~ Enclosed herewith, please find the tabulations of the estimated construction costs for the subject items, and our suggested distribution of these costs between ABQ and Univest. Additionally we have included the Draft Agenda request for this item and a copy of Change Order No. 2 which we are sending to the Contractor for execution. Please note that the Change Order,~ itself ~ ~no~ include the additional costs of Engineerinq,~ Testing and Inspection, which typically run about 10% of the es~ted cost of construction, and should be added to the financial commitments require~--~om ABQ and Univest. In your review of Change Order No. 2 and the draft agenda request, please note that the Original Estimated Contract Amount in the City Council's award of the Contract was $ 1,803,363.03. This amount became the actual budget amount for the paving and drainage improvements covered under the L. H. Lacy Co. Contract. With some cost savings realized by the city through a Contractor proposed price reduction (resulting from having been awarded both Denton Tap projects) Change Orders and Field Changes, the current estimated Contract Amount is $ 1,791,489.06, which technically is $ 11,873.97 under budget. With the addition of the items 17103 Preston Road · Suite 100 · LB 118 · Dallas, Texas 75248 · Phone 214/248-4900 mentioned herein, the budget is technically exceeded by $35,899.33. This budget variation and that associated with the Engineering, Testing and Inspection budget will partially be offset by the Developer financial commitments once they are received. The reason that the budget offset is only partial is that as per our meeting of January 5, 1989 the costs of the west turnout of Parkway Blvd. ~~11 n~ be included in the financia_l commitments. Of the Developer. As you will recall from our discussion major intersections have customarily been treated as a part of the overall project, benefiting the general public as a whole, and not constructed solely for the use of one particular user. Therefore, budget restoration for this item should come from the contingency fund for the project, which to date is ~dequately in tact. Although quite lengthy, I feel the above, with the attachments will give you what you need to bring this item before the City Council. If you need any clarifications, a follow-up briefing, or additional information, please call me at your convenience. Sincerely, Johrf C. Karlsruher, P.E. Project Engineer enclosures cc: H.
