CF-Village-CS 890307 -- !i GINN, INC. CONSULTING ENGiNEEI1-C March 7, 1989 Mr. Russell Doyle, P.E., City Engineer iii..: City of Coppell ~ilil .... Post Office Box 478 Coppell, Texas 75019 ~~~~ Re: Village Par~ay Pump Station Proposed Change Order ~1 Dear Mr. Doyle: We are in receipt of your February 15, 1989 letter, received on February 27, 1989, and wish to offer the following additional info~ation for your consideration. The general contractor on the 4 MG ground storage tank is Preload Construction Company of Garden City, New York. They moved onto the site in mid Septe~er of 1988. At that time, Kimbel Kourt had numerous cracks and exhibited the initial stages of pavement failure. In our opinion, Kimbel Kourt was a sub-standard city street before Preload began construction operations. The construction contracts (with Preload & Cajun) do not contain provisions for the repair or maintenance of city streets. The contracts were bid in good faith that the City of Coppell's streets could withstand normal construction traffic. A contractor can be required to repair damages; however, proving his damages on a sub-standard street will be difficult. The hard freeze in late January was very damaging to most asphalt streets. Even roadways constructed to much stricter standards (i.e. Hwy. 121) experienced significant pavement failures. In summary, we feel the Contractors' have a valid claim not to repair Kimbel Kourt. They do have a responsibility to keep the adjacent roadways clear of debris and mud caused by their operations and we have instructed both Cajun and Preload to better police this situation. As you are aware, the pump station contract is lump sum. Therefore, bid unit prices are not available for evaluation of this Change Order. Cajun Contractors has provided us with a detailed cost breakdown of the work to be deleted and added (see attached). The following is a brief summary of their cost breakdown for the items involved in the proposed Change Order. 17103 Preston Road · Suite 100 · LB 118 · Dallas, Texas 75248 · Phone 214/248-4900 A.

Utility Conflicts: Two conflicts have been discovered which have necessitated a realignment or alteration to the proposed 36" water line along Sandy Lake Road. 1. Discharge Line from Sandy Lake Road Pump Station. The fill line to the existing ground storage tank on Sandy Lake Road is shown on the plans at elevation ±430. This elevation was taken from the drawings of the existing station which were provided to us by the city of Coppell. In actuality, the fill line is at elevation ±437 which poses a conflict with the proposed 36" line to the Village Parkway Reservoir and the existing discharge line of the Sandy Lake Road Pump Station. Since it is impractical, if not impossible to adjust the existing discharge line, one (1) additional bend is being used to go underneath the discharge line. Add one (1) - 14° L-301 Bend @ $1,600/Ea $ 1,600 2. Realign Crossing of Sandy Lake Road. The 48" jack and bore crossing of Sandy Lake Road has been realigned for two reasons. The amount of working room needed for bore pits is projected to be approximately 32'long by 13' deep. At the original angle of 45°, this would have required removing either the entire intersection of Kimbel Kourt and Sandy Lake or one of the bridges into the Corners of Coppell shopping center. The angled crossing would also have caused extensive damage to Bonhards Nursery's landscaping (which is in the right- of-way). We proposed to realign this to a perpendicular crossing to minimize damage to the landscaping and intersection. Delete 50 LF of 48" Jack & Bore @ $300/LF <$15,000> Delete 2 - 45° Bends @ $1,600/Ea < 3,200> Add 1 - 87° Bend @ $2,800/Ea 2,800 Add 52 LF - 36" L-301 Pipe @ $235/LF 12,220 Net Increase / <Decrease> <$ 3,180> Total of Utility Conflicts - <Decrease> <$ 1,580> In exchange for the above considerations, Cajun has offered to scarify, pulverize, and recompact Kimbel Kourt and then apply a 2" HMACP overlay. We have proposed the following specifications for the pavement work: 1) Scarify and Pulverize ±6" in accordance with Texas State Department of Highways and Public Transportation Standard Specifications (TSDHPTSS) Item 250 (Ordinary Compaction). 2) Add Emulsified Asphalt (TSDHPTSS Item 314) at a rate of ±0.5 gal./sq, yd. prior to recompaction. 3) Overlay recompacted subgrade with 2" of Hot Mix Asphaltic Pavement (HMACP) Type D in accordance with TSDHPTSS Item 340. Access will be provided to all tracts at all times. Open cut operations will commence and be completed within 3-4 weeks of approval of this Change Order. Resurfacing of Kimbel Kourt will occur in September or October after completion of most heavy construction operations. It is our estimate that the resurfacing of Kimbel Kourt would cost the City approximately $15,000. Cajun has proposed this resurfacing for a cost of $8,515 which would make the Change Order a net zero in both time and money to the contract. Summary of Changes A. Delete 48" Jack & Bore <$ 6,869> B.

If their position on this proposed Change Order changes due to the clarification of these points, we will notify you. Thank you for your consideration of this proposed Change Order. We feel it will be beneficial to the project and allow the City to accomplish the resurfacing of Kimbel Kourt without the expenditure of additional funds. As we stated in our March 3, 1989 meeting, time is of the essence for approval. Any significant delays in approval may remove the Contractors incentive to pursue the Change Order and cause time delays to the project. If you have any questions or need further information, please feel free to contact us. Sincerely, Sanford W. Case, P.E. attachments cc: Steve Goram H. Wayne Ginn, P.E. Gabe Favre Smoky Ginn J.R.

E. G/nh, Inc. 17103 Preston Road Suite 100 LB 18 Dallas, Texas 75248 RE: VILLAGE PARKWAY PUMP STATION CHANGE ORDER #1 REQUEST Dear Mr. Case: I am in receipt of your February 1, 1989, letter which was received on February 10, 1989 for the above subject change order. It appears that the project has been evaluated and sized up early in its life, but there are some items I will need to know before ! can comfortably recommend this change order as presented. (This is as I discussed with John Karlsruher at the February 14, 1989 City Council meeting). .. Some information will need to come from you, the Project Enginer, and or the Contractor and some will need to be received from the other related officials copied on this letter. When you have your data and information gathered and transmitted then we can set up a meeting to consider the other ramifications and needs. (As John Karlsruher and I discussed on Tuesday evening, you can still call this meeting as soon as possible). CONDITIONS OF KIMBEL KOURT- Please brief me of the responsibility of the contractors building the 4MG ground storage tank and the Village Parkway Pump station regarding city streets and damage caused by their construction equipment. (The ground storage tank contractor is not listed in the February 10, 1989 monthly report.) Please refer to the attached February 14, 1989 Public Works memo. What does the beginning project photographs and/or Project Engineer personnel show for the condition of Kimbel Kourt prior to construction. Items 1 through 3 of your proposal suggest a traditional reduction in unit costs (i.e., boring vs. open cut). Please provide what those unit costs (or at least total costs) are per contract (boring) and as estimated for open cut. Preferable provide unit costs and a total cost by each segment of the project cited. With the four lean conditions listed for open cuts, it is assumed that all other requirements and specifications are provided in the contract or by the City of Coppell standards. Please confirm. Related to the three offerings: Why is the adjustment of the 36" water main necessary on items 1 and 2. Was it not planned for (i.e., project line item)? Just found out? Not the contractor's-responsibility within the contract? What are the specific utility conflicts? Concerning item #3 of the offerings, what specification will be followed in the pulverizing, recompaction progress. Will rejuvating compounds be utilized? What quality control will be used? Will any new asphalt be mixed into the existing pavement? Do we know the pavement cross-sections etc.? Please provide estimated costs on all these offerings for appropriate considerations and comparisons. As we discussed, this may be a wash funding-wise, but we must be accountable for the deal. Regarding the closing of Kimbel Kourt, etc., we need to have that coordination meeting for good planning, coordination and public relations. We need to know, the timings and sequencing of the activities addressed in this Change order (e.g., "how brief of a period" will the old police station be denied access). Have these property owners and businesses been approached on these requests? Even though you recommend this deal is in the best interest of the City of Coppell, I believe when we receive the information requested herein and have the coordination meeting with the other City Department Heads, then we can better tell the bottom line and more importantly carry it to the City Manager and eventually the City Council as a part of the total completion of this Capital Improvement Project. Again, while the change orders bottom line is a wash, it will be healthy to know that the values of trade-offs are. I trust that this request and generation of the information will not prove adverse to the best interests of the Cityp~ Coppell. Your continued commitment to that end will be greatly appfe/iated. Thank you.

' ~ Coppell, Texas 75019 i~ !L L Re: Village Parkway Pump Station Change Order #1 Dear Mr. Doyle: As you are aware, the condition of Kimbal Kourt has deteriorated due in part to the increased traffic related to construction of the 4.0 MG ground storage tank. With the pump station just beginning construction, the road condition is expected to further worsen. To correct this condition, Cajun Contractors, Inc. has approached us with the following proposal: 1) Replace the proposed 48" bored crossings along Sandy Lake Road at Station 24+10, 27+01, and 30+55 with open cut crossings. These crossings are at entrances to the Corners of Coppell shopping center. 2) Replace the proposed 24" bored crossings along Kimbal Kourt at Station 32+74 and 33+72 with open cut crossings. These crossings are at entrances to the Stop-N-Go strip center. 3) Replace the proposed 24" bored crossing of Kimbal Kourt at Station 36+90 with an open cut crossing. All open cut crossings will be subject to the following conditions: 1) No more than one (1) entrance to the Corners of Coppell ~hopping center will be closed at any time. 2) No more than one (1) entrance to the Stop-N-Go strip center will be closed at any time. 3) All concrete drives will be saw cut or removed at expansion joints and replaced per original condition. 4) All open cut operations will be performed in the public right-of-way. 17103 Preston Road · Suite 100 · [.B 118 · Dallas. Texas 75248 · Phone 214/248-4900 In exchange for allowing the above open cut crossings, the contractor is offering the following: 1) Adjust the proposed 36" water main at station 10+87 to avoid utility conflicts. 2) Adjust the proposed 36" water main at Sandy Lake Road to avoid utility conflicts. 3) Prior to completion of the Village Parkway Pump Station project, Cajun Contractors, Inc. will pulverize, recompact, and install a 2" H.M.A.C. surface to Kimbal Kourt from Sandy Lake Road to Village Parkway. We wish to note that this work will require Kimbal Kourt to be closed during the boring of Sandy Lake Road, the open cutting at Station 36+90, and for resurfacing. The only facility which will be briefly denied access during this process is the old Police Station on Kimbal Kourt. The contractor has proposed this Change Order at no change to the contract amount. We believe it is in the City's best interest to accept this change order. If you concur, please forward this Change Order to Mr. Ratliff for his approval. If we can be of further assistance or if you have any questions, please contact us. Sincerely, San%ord W. Case, P.E. attachment cc: Steve Goram Karl Hirschey, Cajun Contractors, Inc. H. Wayne Ginn, P.E. File 380 COPPELL PUBLIC WORKS MEMORANDUM February 14, 1989 TO: Sanford Case, Ginn Inc. FROM: Per Birdsall, Street Foreman RE: Kimbell Kourt I was required to make an inspection of the road Kimbell Kt. recently due to complaints received. The road's condition, as expected, has deteriorated rapidly due to the heavy loads experienced during the continuing construction of the new ground storage facility. This condition has also been duly noted by the Director of Public Works. Please have the Contractor submit his intentions for the repair of directly affected portions of that road and for street sweeping of Kimbell Kt., Village Pkwy., and MacArthur Blvd., which have been tracked with dirt from the construction site. This should be accom- plished within a reasonable period of time after operations which have caused these situations to occur or when deemed necessary to prevent loss of life or property.
