Box 540787 Dallas, TX 75354-0787 Re: Sandy Lake Road Project # ST 93-02 Proposed Change Order for the extension of Sandy Lake Road (Ma( CDS - , DKi Dear Mr. Weber: I have received your preliminary costing for the extension of Sandy Blvd. to Kimbel Court. I was somewhat surprised by the overall total and in particular the total for mobilization, right-of-way preparation, field office, traffic signal installation, temporary roadway, storm water prevention plan and pavement markings. I also have questions that need to be resolved concerning why quantities were changed for unclassified street excavation, lime subgrade, hydrated lime, 8" concrete paving, 6" concrete curb and 4" top soil. There were other minor quantity changes throughout the estimate, however, the above referenced ones are the ones that concern me most. During the pre-bid meeting of July 21, 1998, the extension of Sandy Lake Road was discussed at length and it was noted that this would potentially be assigned as a change order to the low bidder on the project. The key item was that it was our intent to assign it as a change order not as extra work for which new prices would be calculated. If the cost of the extension was greater than 25 % of the total project, then there could be some validity to it not being classified as a change order. However, the cost of the extension is not 25 % of the project. The following represents my concern with the costing for the pay items previously mentioned: Mobilization - The specifications for Sandy Lake Road state that mobilization is not to exceed 5 % of the total value of the work minus the cost for mobilization. Using the numbers that you submitted i.e., not adjusting the areas where I think that they are out of line, the maximum mount of the mobilization on this change 'order would be $51,758. However, even that number should be adjusted downward based on adjustments in the other bid items on the proposed change order. On your original bid you estimated about $41/pe, r foot for mobilization. Using that number for the 766 feet of the change order would equal Robert Weber, Project Engineer Ed Bell Construction 10605 Harry Hines Blvd. P.O. Box 540787 Dallas, TX 75354-0787 Coppell, Texas 75019 972-462-0022 February 14, 2000 Re: Sandy Lake Road Project # ST 93-02 Proposed Change Order for the extension of Sandy Lake Road (MacArthur Blvd. to Kimbel Ct.) Dear Mr. Weber: I have received your preliminary costing for the extension of Sandy Lake Road from MacArthur Blvd. to Kimbel Court. I was somewhat surprised by the overall total and in particular the total for mobilization, right-of-way preparation, field office, traffic signal installation, temporary roadway, storm water prevention plan and pavement markings. I also have questions that need to be resolved concerning why quantities were changed for unclassified street excavation, lime subgrade, hydrated lime, 8" concrete paving, 6" concrete curb and 4" top soil. There were other minor quantity changes throughout the estimate, however, the above referenced ones are the ones that concern me most. During the pre-bid meeting of July 21, 1998, the extension of Sandy Lake Road was discussed at length and it was noted that this would potentially be assigned as a change order to the low bidder on the project. The key item was that it was our intent to assign it as a change order not as extra work for which new prices would be calculated. If the cost of the extension was greater than 25 % of the total project, then there could be some validity to it not being classified as a change order. However, the cost of the extension is not 25 % of the project. The following represents my concern with the costing for the pay items previously mentioned: Mobilization - The specifications for Sandy Lake Road state that mobilization is not to exceed 5 % of the total value of the work minus the cost for mobilization. Using the numbers that you submitted i.e., not adjusting the areas where I think that they are out of line, the maximum amount of the mobilization on this change 'order would be $51,758. However, even that number should be adjusted downward based on adjustments in the other bid items on the proposed change order. On your original bid you estimated about $41/pe.r foot for mobilization. Using that number for the 766 feet of the change order would equal approximately $31,000. So therefore, a request for mobilization of $285,000 does not seem to be inline with this change order. Right-of-way preparation - You originally bid $125,000 for 9,828 feet, which is slightly over $12/per foot. If you utilize that cost per foot on this change order we should have a right-of- way preparation cost of approximately $9,363 not $60,000 as submitted. Field office - This was originally bid at $20,000 for 850 calendar days or approximately $23.53 per/day of the project. Your letter requests an extension of 120 days for this work. Therefore, I would anticipate that the field office cost would be in the range of $2,824, not $24,000 as submitted. It is also interesting to note that the $24,000 is $4,000 more than the original bid for the field office that was anticipated to be on the job site for 850 days. Traffic signal installation - There were three traffic signals proposed on the original Sandy Lake Road project (Samuel, Moore and Heartz). Those range in cost from $88,000 to $110,000, complete and in place. Even though the MacArthar intersection is somewhat wider which could entail some additional conduits, I did not anticipate a traffic signal installation cost double the highest traffic signal cost originally bid on the project. The request for $220,000 for the traffic signal at MacArthur appears to be out of line for this change order. Temporary roadway - The original bid included temporary roadway for approximately $75,000 for a distance of 9,828 feet. That was bid as a lump sum item. That would be approximately $7.63 per/foot of the roadway. Temporary roadway for an extension of 766 feet should be more in the range of $5,850, as opposed to your $50,000 request. Also, the $50,000 request is 2/3's of the cost for the entire original bid on temporary roadway. Storm water pollution plan - The original bid for the storm water pollution plan was $40,000 for a project of 9,828 linear feet or approximately $4.07/per foot. I would anticipate a storm water pollution plan cost of approximately $3,120 for this change order, not the $20,000 as proposed. Pavement markings - On the original bid pavement markings were $60,000 for 9,828 linear feet of roadway or approximately $6.11/per linear foot. I would anticipate a change order for the 776 feet in the range of $4,685, not $22,000 as submitted on the change order. Some other items to note for clarification on the change order: Lime subgrade should be 8-inch lime subgrade in accordance with the Sandy Lake Road plans, not 6 inches as shown on the description of the pay items. It appears that Pay Item t/18 2" Type D Hot Mix is not needed for this project. The plans were designed by a different consultant and it appears they anticipated an 8-inch transitional paving, not the 6-inch as proposed in the original Sandy Lake plans. In our Sandy Lake Road plans we provide for 6-inch hot mix transition paving as 4 inches of Type B and 2 inches of Type D. There were various new items on the proposed change order which were not covered by the Sandy Lake Road original bid. In my review of the pay items it appears that the following are new items: removing the guardrail, removing concrete flumes, removing bricks/stonewall, removing electrical box, 6" Type D hot mix curb, concrete header, metal beam guardrail, laydown terminal, 10" PVC sewer, 21" PVC sewer, adjusting existing sanitary sewer manholes, adjusting existing water meter valve boxes and the 2" PVC conduit. My initial review of the extension of Sandy Lake Road based on the 95 % complete plans of which we provided you and the way that Sandy Lake Road was originally bid indicate that this change order should be in the range of $800,000 not $1.3 million as submitted. We are approximately $500,000 apart on what in my opinion should be the value for the change order. If this change order cannot be reevaluated and brought more inline with the original Sandy Lake Road bid items on value, then it appears the only option left to the City would be to generate a completely separate set of plans to put out to bid. That means two contractors, unless your firm is the low bidder, would be working along the Sandy Lake Road corridor during the same timeframe. As soon as possible we need to sit down and discuss this proposed change order so that the City can make a determination on which direction to proceed. Thank you for your consideration of this matter and I will walt to hear from you. Sincerely, Kenneth M. Griffin, P.E.

Director of Engineering and Public Works City of Coppell 255 Parkway Blvd. Coppell, Texas 75019-4409 Rc: Sandy Lake Road Reconstruction Coppell Project #: ST 93-02 Kimley-Horn Project #: 06940600 DWU Project #: 98-311F Dear Mr. Griffin: We have reviewed the October 29, 1999 plans for the MacArthur Boulevard and Sandy Lake Road intersection improvements. Our prices for the work identified in that set of plans are enclosed for your review and apprOVaL We have nOt quoted the four Street light poles because the light poles on the remainder of the project will be done by others; however, we have quoted the conduit for the street lights. Because of the phased nature of the intersection, coordination of the conduit installation in the intersection will be more efficient utilizing an EBCC subcontractor rather than bY waiting for a TXU subcontractor. We envision constructing this intersection by installing all of the utilities and then constructing the intersection in quadrants. This work will be completed utilizing four to six traffic switches at Z/ the intersection that will require temporary signal work at the intersection and detour work east of MacArthur. We will need an additional 120 calendar days to complete this work. If you have any questions' regarding this information, don't hesitate to contact our office. ~d~,?erely, ~f~ l~~.~e Co struc Company Robert B. Weber Project Engineer XC: Michael G.
