Over the past several weeks we have been researching the recommended hang weights for 3-inch and 4-inch schedule 80 drop pipe equipped with the largest weight capacity couplings that are available in the pipe industry. We have requested from all of our pump suppliers their recommended maximum pump setting and hang weights utilizing both 3-inch and 4-inch schedule 80 mild steel pipe and 3K full heavy couplings and none of them were able to provide Us with this data. There has been a substantial change in both the depth of these four pump settings and the weight of these four pumps located at El Porvenir and Cantua Creek. There are several conditions that have changed since this project was originally bid including: 1)deeper pump settings on all four pumps;2) different larger capacity and longer submersible pump bowls; 3) different larger capacity submersible motors;4)thicker drop pipe/column pipe changing From schedule 40 to schedule 80 mild steel piping; 5) thicker couplings on both the 3-inch and 4-inch schedule 80 steel pipe; and 6) heavier total pump, motor and column water weights due to these required changes to meet these changes in the pumping conditions. The first chart(Exhibit 1) included in the attachments is a chart displaying the maximum suggested pump setting from Grundfos utilizing schedule 40 standard T&C Steel Pipe with standard couplings is 1250 feet for 3-inch I.D. pipe and 1100 feet for 4-inch I.D.pipe. A second chart(Exhibit 2) included in this attachment is from the Grundfos Engineering Manual displaying the pipe data for both 3-inch I.D. and 4-inch I.D.schedule 40 and schedule 80 pipe, but does not display a maximum suggested pump setting. The third thru fifth attached PDF files contains a summary of the calculated weights of both the 3-inch and 4-inch pumps including the water weight of the pumps with pump column pipe full of water for the following three pump designs: 1)the four pumps as originally specified and set to the originally contracted depths of 756 feet at El Porvenir and 630 feet at Cantua Creek utilizing schedule 40 mild steel column pipe and standard couplings as originally contracted(Exhibit 3);2)the four pumps that would be required to be set at the new required depths of 1197 feet at El Porvenir and 798 feet at Cantua Creek in order to meet the changes in the pumping conditions utilizing schedule 40 mild steel pipe and standard couplings(Exhibit 4); and 3) )the four pumps currently proposed to be set at the required depths of 1197 feet at El Porvenir and 798 feet at Cantua Creek in order to meet the changes in the pumping conditions utilizing schedule 80 mild steel pipe and heavy couplings(Exhibit 5). As stated above,we have had several conversations over the past several weeks with ail of our pump suppliers regarding the maximum recommended pump settings utilizing both schedule 40 black mild steel pipe with standard couplings for the 3-inch and 4-inch column pipe for these four pumps;and schedule 80 black mild steel pipe with heavy couplings for the 3-inch and 4-inch column pipe for these four pumps. Because no manufacturer or supplier was able to provide us with a recommended maximum hang weight or recommended maximum pump setting utilizing 3-inch and 4-inch schedule 80 mild steel pipe with heavy couplings to set these four pumps,we have calculated the estimated pump weights and compared these weights to the calculated joint strength of the 3-inch and 4-inch schedule 80 mild steel pipe with heavy couplings. In Exhibit#3,we have calculated the estimated pump weights of these four originally specified and contracted pumps full of water in order to display the total pump weights of the originally specified schedule 40 steel pipe pump settings. The estimated pump weight of each of the two 3-inch pumps full of water at CSA 30 set to a depth of 756 feet and specified utilizing 3-inch schedule 40 steel pipe and standard couplings is 11,118 pounds;and the estimated pump weight of each of the two 4-inch pumps full of water at CSA 32 set at 630 feet and specified utilizing 4-inch schedule 40 steel pipe and standard couplings is 13,606 pounds. The Grundfos chart(Exhibit 41)recommends that the maximum 3-inch pump setting utilizing schedule 40 mild steel pipe and standard couplings is 1250 feet or approximately I 18,387 pounds(14.71 pounds/foot x 1250 feet). The Grundfos chart also recommends that the maximum 4-inch pump setting utilizing schedule 40 mild steel pipe and standard couplings is 1100 feet or approximately 23,760 pounds(21.60 pounds,/foot x 1100 feet). Based upon these calculated pump i weights and Grundfos chart recommendations,all four originally specified and contracted pumps being set at their originally specified settings could be installed without any concern of their respective pump weights. All four pump total weights set at these originally contracted pump settings are less than 60% of the maximum recommended hang weights utilizing schedule 40 mild steel pipe and standard couplings. Additionally,(in Exhibit#4)we have calculated the estimated pump weights of these four pumps full of i water to assess whether the originally specified schedule 40 steel pipe with standard couplings will still work for these required new deeper required actual pump settings. The estimated pump weight of each of the two 3-inch mild steel pipe pumps full of water at CSA 30 set at 1197 feet and specified utilizing 3- inch schedule 40 steel pipe and standard couplings is 17,325 pounds;and the estimated pump weight of each of the two 4-inch schedule 40 mild steel pipe pumps full of water at CSA 32 set at 798 feet and specified utilizing 4-inch schedule 40 steel pipe and standard couplings is 16,736 pounds. The maximum setting utilizing 3-inch schedule 40 steel pipe and standard couplings is 1250 feet; and the maximum setting utilizing 4-inch schedule 40 steel pipe and standard couplings is 1100 feet. The two 3-inch schedule 40 mild steel pipe pumps at CSA 30 with settings of 1197 feet weigh 17,325 pounds and are at 9S%of the maximum weight limits of 18,387 pounds for utilizing schedule 40 steel pipe with standard couplings;and the two 4-inch schedule 40 mild steel pipe pumps at CSA 32 with settings of 798 feet weigh 16,736 pounds and are at 71%of the maximum weight limits of 23,760 pounds for utilizing schedule 40 steel pipe and standard couplings. Despite the fact that the total pump weights of these specified pumps utilizing schedule 40 pipe with standard couplings will stay below their respective maximum setting thresholds,we do not recommend utilizing schedule 40 mild steel pipe with standard couplings on these deep pump settings because both the schedule 40 pipe and the thinner wall standard couplings tend to flex and egg shape when these amounts of weight are hung from them. When the pipe and/or couplings flex and become egg shaped,there is a good chance that the threads won't hold, the pipe will slip out of the coupling,and the pump will be dropped. This potential joint failure could occur during both our initial installation or in the future when the pump is pulled for maintenance, rehabilitation or repair of either the well or the pump. Instead,on these four deep pump settings,we recommend that Fresno County utilizes schedule 80 mild steel pipe with heavy couplings because both the schedule 80 mild steel pipe and the heavy couplings are thicker and will not flex or become egg shaped when holding the pump weights of these deep pump settings. Furthermore,as discussed during our meeting on November 16, 2022,the thicker material of the schedule 80 steel pipe and heavy couplings will provide additional expected longevity for these four pumps. Finally, (in Exhibit#5)we have calculated the estimated pump weights of these four pumps full of water to display the weights of the required pumps set at the required deeper pump settings utilizing schedule 80 mild steel pipe with heavy couplings. The estimated pump weight of each of the two 3-inch pumps full of water at CSA 30 set at 1197 feet and specified utilizing 3-inch schedule 80 steel pipe and heavy couplings is 20,118 pounds;and the estimated pump weight of each of the two 4-inch pumps full of water at CSA 32 set at 798 feet and specified utilizing 4-inch schedule 80 steel pipe and heavy couplings is 19,655 pounds. We then calculated the joint strengths of 4-inch ID and 3-inch ID schedule 80 mild steel pipe with heavy couplings utilizing a safety factor of 3. Exhibit#6 displays the recommended maximum weight setting utilizing 3-inch schedule 80 steel pipe and heavy couplings is 23,138 pounds or 1376 feet(23,138 pounds /16.81 pounds per foot);and Exhibit#7 displays the recommended maximum weight setting utilizing 4- inch schedule 80 steel pipe and heavy couplings is 23,273 pounds or 944 feet(23,272 pounds/24.63 pounds per foot). The two 3-inch schedule 80 mild steel pipe pumps at CSA 30 with settings of 1197 feet weigh 20,118 pounds and are at 87%of the maximum weight limits of 23,138 pounds for utilizing schedule 80 steel pipe and heavy couplings; and the two 4-inch schedule 80 mild steel pipe pumps at CSA 32 with settings of 798 feet weigh 19,655 pounds and are at 85%of the maximum weight limits of 23,273 pounds for utilizing schedule 80 steel pipe and heavy couplings. We recommend that the schedule 80 mild steel pipe with the heavy couplings be utilized on all four pumps because all four pumps have total pump weights well under the maximum recommended weight capacity of schedule 80 mild steel pipe with heavy couplings of approximately 23,000 pounds for all pumps utilizing either 3-inch or 4-inch mild steel pipe with heavy couplings. Because the maximum recommended weight capacity of schedule 80 mild steel pipe with heavy couplings has been calculated using a safety factor of 3,the actual maximum hang weight of schedule 80 mild steel pipe with heavy couplings utilizing either 3-inch or 4-inch mild steel pipe is approximately 69,000 pounds. In addition, because both the pipe thickness and the coupling thickness of schedule 80 mild steel pipe with heavy couplings is greater than the pipe thickness and coupling thickness of schedule 40 mild steel pipe with standard couplings,there is little to no chance that the schedule 80 mild steel pipe or heavy couplings will flex or become egg shaped during the pump installation at these new deeper settings. While we are confident that utilizing the schedule 80 mild steel pipe with heavy couplings to set these new deeper and larger required pumps and motors,Zim Industries,Inc.recommends that the County of Fresno have their engineering team review this data included in this email the attached PDF files. While Zim Industries, Inc. is the general contractor,we are not the design engineer and we have not been contracted to perform the duties of the design engineer for the County of Fresno on this project. With that being said, based on the above stated pump weights and calculated joint strengths of the 3-inch and 4-inch schedule 80 mild steel pipe with heavy couplings,we recommend that 3-inch and 4-inch schedule 80 mild steel pipe with heavy couplings be utilized to set these four pumps on this project. 2) The County of Fresno is looking for proof of AIS certification See the attached Exhibit 8 containing the proof of American Iron and Steek Certification of the 3-inch ID and 4-inch ID schedule 80 mild steel pipe materials from our pump supplier. 3) The County of Fresno is asking that Zim Industries will split the cost of the purposed change order 50/50. The revised pricing of Zim Industries, Inc.'s cost proposal to furnish and install the four pumps utilizing 3- inch and 4-inch schedule 80 mild steel pipe with heavy couplings at the deeper pump settings required for CSA 30 and CSA 32 to meet the changes in pump,motor and pumping conditions is attached as Exhibit 9. Below is a summary of our revised proposals. Description of Work Original Bid Revised Bid Change Order Request CSA 32—Cantua Creek Well 1 $73,750.00 $112,218.16 $38,468.16 CSA 32—Cantua Creek Well 2 $73,750.00 $112,218.16 $38,468.16 CSA 30—El Porvenir Well 1 $78,720.00 $ 88,645.34 $ 9,925.34 CSA 30—El Porvenir Well 2 $78,720.00 $ 88,645.34 9,925,34 Total revised Change Order Request Amount $96,787.00 The change in conditions of the required pump, motor,column pipe and pump setting has required nearly every component of these four pumps to both change and increase in quantity from when we contracted this work. Zim Industries, Inc.disagrees with the County of Fresno's request to split these cost increases equally between Zim Industries, Inc. and the County of Fresno. All of these proposed pump cost increases are due to the fact that pumps are being set deeper,and the pump components are being increased in size,weight and footages to meet the change in the pumping conditions of these four wells. These proposed cost increases are summarized below because of these following pump component changes and quantity increases: 1)the pump settings went from 756 feet to 1197 feet on the two pumps located at CSA 30; and 2)the pump settings went from 630 feet to 798 feet on the two pumps located at CSA 32;3)the submersible pump bowl changed from 15 stages to 25 stages on the two pumps located at CSA 30;4)the submersible pump bowl changed from 11 stages to 23 stages on the two pumps located at CSA 32; 5)the submersible motor changed from 20 HP to 30 HP on the two pumps located at CSA 30;6)the submersible motor changed from 40 HP to 50 HP on the two pumps located at CSA 32;7)the column pipe changed from 756 feet of 3-inch coated schedule 40 mild steel pipe with standard couplings to 1197 feet of 3-inch schedule 80 mild steel pipe with heavy couplings on the two pumps located at CSA 30; 8)the column pipe changed from 630 feet of 4-inch coated schedule 40 mild steel pipe standard couplings to 798 feet of 4-inch schedule 80 mild steel pipe with heavy couplings on the two pumps located at CSA 32;9)the number of 3-inch diameter check valves changed from 4 each to 6 each on the two pumps located at CSA 30; 10)the number of 4-inch diameter check valves changed from 3 each to 4 each on the two pumps located at CSA 32;11)the submersible cable changed from 1000 feet of 6/3 Flat Jacket Cable to 1500 feet of 2/3 Flat Jacket Cable on the two pumps located at CSA 30; 12)the submersible cable changed from 1000 feet of 4/3 Flat Jacket Cable to 1000 feet of 2/3 Flat Jacket Cable on the two pumps located at CSA 32; 13)the footage of#14 wire changed from 2000 feet to 3000 feet on the two pumps located at CSA 30; 14)the pump airline changed from 756 feet of 1%"schedule 80 PVC airline to 1200 feet of l"stainless steel airline on the two pumps located at CSA 30;and 15)the pump airline changed from 630 feet of 1%" schedule 80 PVC airline to 800 feet of%"stainless steel airline on the two pumps located at CSA 32. We respectfully request that the County of Fresno approve our request for this contract price increase to compensate Zim Industries, Inc.for the pump changes, motor changes and pump setting changes required to meet the change in pumping conditions of the two wells at CSA 30 and the two wells at CSA 32. We have contacted our pump supplier for lead times on the remaining 3-inch and 4-inch mild steel schedule 80 drop pipe with heavy couplings for these four pumps(two pumps at CSA 32 and two pumps at CSA 30)and the lead times for manufacturing and delivery is 10 to 12 weeks. We have ordered all of the other pump components included in our proposal except for the 3-inch and 4-inch schedule 80 mild steel:drop pipe with heavy couplings. Once we have the County of Fresno's approval for utilizing this schedule 80 mild steel material with heavy couplings for both the 3-inch and 4-inch pump settings,we will proceed with ordering it from our supplier and finalize our work schedule. We look forward to finalizing the pump designs of these four pumps,ordering the 3-inch and 4-inch schedule 80 mild steel column pipe with heavy couplings and completing this project as soon as possible.

The Covid-19 pandemic and subsequent supply chain disruptions resulted in significant delays and increases in material costs, which have had a profound impact on our operations. The delays in finalizing the pump equipment designs, combined with these industry-wide challenges, resulted in significantly higher costs for electrical conduit and wire by the time final designs were confirmed. Extended lead times and fluctuating prices due to the pandemic disrupted our procurement and planning. Suppliers could not offer reliable delivery schedules or pricing, and challenges in retaining and training our workforce further complicated our operations. These disruptions severely affected our ability to manage costs and schedules, contributing to increased electrical material costs. After the pump tests,it was evident that new pump equipment designs were required. This resulted in new pump designs with larger horsepower motors and, in turn, electrical design modifications, consisting of larger horsepower soft starters and larger wire sizes. Delays in finalizing these modifications,combined with ongoing industry-wide issues, resulted in a significant increase in electrical material costs. Attached, please find the documentation from our electrical subcontractor and their supplier outlining the additional costs for conduit and wire incurred during this period. Components with minimal cost increases have been excluded. Our proposed adjustment,with a 15%markup and bond cost,amounts to$55,929.37. If you have any questions or need further information, please do not hesitate to contact Bob Zimrnerer or me at (559)834-1551. We appreciate your consideration and look forward to your response.

Since 2020 the average material cost has increased significantly. Independent Electric Supply has experienced unprecedented pricing increases and lead time due to the impacts of Covid-19 and the resulting global supply chain crises our vendors are experiencing,which has affected many projects. We estimated on average the cost of material has increased from 25-30%since the beginning of 2022 and will continue to rise through 2023. nla S/100 LF S/1000 LF S/LF S/LF Size EMT PVC Size Wire Size PVC Size Wire 1/2 42 30.5 12 120.806 1/2 0.31 12 0.12 3/4 40.421 10 185 3/4 0.40 10 0.19 1 11 .928 33.098 8 247.483 1 0.33 8 0.25 1-1/4 22 53 43.831 6 381.22 1-1/4 0.44 6 0.38 1-1/2 235. 04 55.833 4 577.716 1-1/2 0.56 4 0.58 2 299. 79.25 2 1425.579 2 0.79 2 1.43 2.5 485.3 105 1/0 1632.041 2.5 1.05 1/0 1.63 3 587.76 120.46 2/0 2057.241 3 1.20 2/0 2.06 4 894.85 163.83 3/0 2972,862 4 1.64 3/0 2.97 4/0 3350.86 4/0 3.35 250mcm 3714.201 250mcm 3.74 400mcm 5645.504 400mcm 5.65 500mcm 8486.19 500mcm 8.49 Sincerely Gayne Alexander Branch Manager www.iesupply.com Exhibit D 4532 E.Jefferson Ave. • Fresno, CA 93725 Ph.

During pump installation, we proactively included these level probes, attaching them to the column pipe; however,installation of a relay is still required. Implementing these level probes will provide the following benefits: o Automatically shut off the pump if the water level drops to 50 feet above the pump bowls. • Trigger a warning if the water level rises to 350 feet above the pump bowls,allowing for early intervention. These probes offer a direct and reliable method for monitoring water levels and can be combined with other protective measures,such as float switches or pressure sensors,ensuring comprehensive system protection. Attached is our subcontractor's proposal for these upgrades. Including bond cost and a 15%markup,our proposal amounts to$8,120.00.
