Watertower St Suite 100 Meridian, Idaho 83642 Re: City of Meridian -Well No. 27 Dear Kyle: (208)888.4312 Fax sss-os23 November 5, 2008 Our Agreement for Professional Services for the We1127 project was executed in November 2004. Since then, the project has changed adding additional work effort not anticipated when the original scope of services was prepared. I am requesting a supplement to the original agreement to cover this additional work and adjust for the four year delay in completion of this project. I have enclosed a copy of the original executed agreement far your reference. I have also attached a summary of all billings as of 11/4/08. As of November 4, 2008 we have billed a total of 18,474 for design fees. This number is $900 higher than shown on my November 4 bllling due to the fact that I had not included my March 5, 2006 billing in my budget summary. Twill oorreet this during the next billing cycle. Work that I consider a change in scope is as follows: 1. The Cherry bane Christian Church needed to install landscaping along the northerly edge of their property in April 2006. This required that the by-pass/flushing pipeline from the well lot to Ten Mile Creek be constructed as a separate project. The separate project added design effort and construction staking that was not originally included in the scope of services. I estimate the fees for additional work associated with this change are one half of Bills No. 2 and 3 and all of Bill No. 4 for a total of $2,185.00. 2. When We1127 was actually constructed it was found to be a flowing artesian well. This required that we prepare a special separate detail for a well head capable of diverting the artesian flow during development and test pumping. Since you still planned to postpone design and construction of the pumping facilities, Ed Squires recommended that you have the ability to flush the well to preserve water quality until the pumping facilities are installed. This required that we prepare a separate set of design plans for improvements to handle the artesian flow until the pumping facilities are constructed. I estimate the fees for additional work associated with this change are all of Bill No. 6 and one half of Bills No. 9, 10 and all of Bills No. 11 and 12 for a total of $5,036.50. Radek November 5, 2008 Page 2 of 3 3. When the original scope of services was prepared city policy was that the contractors install a SCADA panel and antenna furnished by Meridian. All SCADA start-up and progranuning was performed by Meridian once the well was completed and accepted. This policy has now changed so that the equipment will be furnished by the contractor as part of the construction contract and SCADA programming will be provided under the design services contract. DC Engineering's fee proposal for the SCADA programming is $2,500.00. 4. You have requested the new pumping facilities include the ability to by-pass flows whenever the well starts after remaining idle. This requirement was not included in the original project. The License Agreement with the Nampa Meridian Irrigation District allowing for flows to be by- passed to Ten Mile Creek was obtained prior to this new requirement and does not allow for this type of discharge. A modification to the existing agreement will be required. Since Ten Mile Creek is a drain rather than a canal I anticipate that obtaining this modification will be possible, but I have not approached NMID regarding this issue at this time. Assuming everything goes smoothly, I estimate approximately 8 hours of Project Engineer time will be required to update the license agreement, which will add approximately $760.00. This does not include any direct expenses for charges by NMID's attorney, which I will pass through at cost. 5. Originally Well 27 was to be constructed in 2005. Construction was delayed due to water quality issues discovered when the test well was constructed, and due to changes in anticipated demands in the area. Billings submitted to date have been made at the current hourly rate at the time of billing. There are some original budgeted hours that are not currently billed, or included in another supplement item, for which I am requesting an increase to adjust to current rates. I have attached two spreadsheets to support this request, one for the design fees and one for the construction services fees. The combined total for this item is $4282.50. 6. 1 originally planned to use Mulder Engineering for electrical design and Kartchner Engineering for mechanical design. On my recent projects I have been using the services of DC Engineering for both electrical and mechanical design. It is my understanding that DC Engineering is also providing most of the SCADA programming for Meridian making them a good choice for this project. I have enclosed a copy of their proposed scope of services and fee estimate. This proposal includes $5,000 for electrical and mechanical design, which is $300.00 over the original budget. The following summarizes the fee adjustments requested above by item number: Change No. 1 Change No. 2 Change No. 3 Change No. 4 Change No. 5 Change No. 6 Total Fee Increase _ $ 2,185A0 $ 5,036.50 _ $ 2,500.00 _ $ 760.00 $ 4,282.50 _ $ 300.00 _ $15,064.00 Radek November s, x008 Page 3 of 3 1 spoke to 1?d Squires this morning regarding the well. He indicated that his proposal to restrict portions of the well screens for water quality purposes should not affect the selection or design of the pumping equipment. Ed is not finished with this design, but indicated he would have well capacity and drawdown information tome by next week. For purposed of this supplement Y have assumed we wil! have a standard vertical turbine pump configured for the artesian well. Please let me know if you need any additional information to support this request. enc. Sincerel . ~~~~ im Burgess, P.E. Clam K. Bennett' P.t_S. Civil Survey Consultants, Inc. PresideM 1400 E.

P.E. vice President Meridian, Idaho 83642 Mays, 2009 Brent Blake City of Meridian 33 East Broadway Avenue Meridian, Idaho 83642 Re: City of Meridian -Well No. 27 Dear Brent: During the review and approval process for We1127 the Idaho Department of Environmental Quality (IDEQ) added two new requirements to the project that were not include in our professional services agreement. These requirements added additional work effort and costs as follows: 1. IDEQ rejected our original plan submittal due to the fact that a Preliminary Engineering Report had not been submitted and approved. The requirement for the Preliminary Engineering Report has been added since the original wntract, and IDEQ would not accept your approved Master Plan as fulfilling the requirement even though We1127 is specifically addressed in the Master Plan. This issue caused additional services in the amount of $1,050.00 as shown in our February 2, 2009 biping. 2. IDEQ added the requirement that we install a pressure relief valve on the distribution side of the check valve. It is my professional opinion that IDEQ's position on this issue is not supported by the current version of iDAPA 58.01.08, and was a very broad interpretation of the regulations to support their requirement. This has not been a requirement on any of the previous well projects we have completed for Meridian. This issue caused additional services to address 1DEQ's comments and make plan revisions in the amount of $1,754.41, which was included in the April 3, 2009 billing. I am requesting a supplement in the amount of $2,804.41 for these additional services. Please let me know if you need any additional information to support this request. Sincerely, ` ~ ~` 1'im Burgess, P.E.
