Item 3.8 West WWTF Improvements Project Change Orders Request for City Council Action DEPARTMENT INFORMATION ORIGINATING DEPARTMENT REQUESTOR: MEETING DATE: Utilities Utility Manager Neidermeier July 28, 2025 PRESENTER(s) REVIEWED BY: ITEM #: Consent AE2S Engineer Schaefer Assistant City Administrator/Human Resources Hille 3.8 – West WWTF Project Change Order Proposals STRATEGIC VISION MEETS: THE CITY OF OTSEGO: Is a strong organization that is committed to leading the community through innovative communication. X Has proactively expanded infrastructure to responsibly provide core services. Is committed to delivery of quality emergency service responsive to community needs and expectations in a cost-effective manner. Is a social community with diverse housing, service options, and employment opportunities. Is a distinctive, connected community known for its beauty and natural surroundings. AGENDA ITEM DETAILS RECOMMENDATION: City Staff is recommending that the City Council approve change orders for the West WWTF project. ARE YOU SEEKING APPROVAL OF A CONTRACT? IS A PUBLIC HEARING REQUIRED? No No BACKGROUND/JUSTIFICATION: A package of Change Order Proposals for the West WWTF project were reviewed with the Public Works Subcommittee (PWSC) on July 16, 2025. The following table is a summary of the change orders that were recommended to forward for consideration by the full Council. CPR 74 UV Building Extra Work $10,182 CPR 76 Additional Grating in PTB $14,981 CPR 77 Add Baffle Walls in PTB tanks $30,051 CPR 78 Miscellaneous Changes Group A – Process Piping and Channels $23,457 CPR 79 Miscellaneous Changes Group B – Earthwork and Sitework $13,723 CPR 80 Miscellaneous Changes Group C – Instrumentation $3,009 CPR 81 Miscellaneous Changes Group D – Buildings/Structural $3,203 CPR 82 Natural Gas Use Credit ($15,927) The change orders represent various justifications ranging from necessary modifications to “pass-through” utility costs to complete the project. Note that the #77 did not have final pricing on July 16, and the cost increase was due to shipping. The proposed net increase in project cost of $83,129 represents 0.245% of the bid cost and would bring the total change order plus authorized direct purchase items amount to a net increase to 5.30% for the project. SUPPORTING DOCUMENTS ATTACHED: • Detailed proposals for change orders 74 and 76 through 82 POSSIBLE MOTION PLEASE WORD MOTION AS YOU WOULD LIKE IT TO APPEAR IN THE MINUTES: Motion to approve Change Order Proposals #74 and #76 to #82 as indicated in the table above in the amount of $83,129 to Rice Lake Construction Group for the West WWTF Project.

DIV 08 and DIV 26 REQUEST The proposed location of the overhead door in the UV building appears to conflict with existing equipment and piping in the UV building. Note 3 on UV E102 states that the electrical contractor must disconnect the existing compressor and all the associated cable and conduit back to the source. There is additional water/air piping and conduit inside of the wall that would need to be removed in this location. If Rice Lake is to install the overhead door in this location, there will be associated costs with the extra demo work. Please advise if Rice Lake should install the door in the location shown on the plans, or if the opening should be moved to a different location in the building. See attached photo of extra pipe and conduit in this area.

GENERAL 2.1 Any quotation is not an offer to sell Goods. All orders by Customer for the Goods (“Orders”), if accepted by Company in its sole discretion, will be accepted subject only to these Terms. DIFFERENT OR ADDITIONAL TERMS PROPOSED BY CUSTOMER ON OR IN CONNECTION WITH CUSTOMER’S PURCHASE ORDER FORMS OR OTHER DOCUMENTATION SHALL NOT APPLY TO THE PURCHASE OF GOODS HEREUNDER AND ARE HEREBY EXPRESSLY REJECTED AND SHALL NOT BECOME PART OF THE CONTRACT. COMPANY’S AGREEMENT TO SELL GOODS TO CUSTOMER IS EXPRESSLY LIMITED TO THESE TERMS AND, IF APPLICABLE, A WRITTEN AND SIGNED AGREEMENT BETWEEN CUSTOMER AND COMPANY TO WHICH THESE TERMS ARE ATTACHED. 2.2 Company reserves the right at any time prior to Delivery, to increase the price of the Goods to reflect any increase in the cost to Company which is due to any factor beyond the control of Company (including but not limited to, any foreign exchange fluctuation, currency regulation, alteration of duties, significant increase in the costs of labor, materials or any other costs of manufacture), any change in Delivery dates, quantities or specifications for the Goods which is requested by Customer, or any delay caused by any instructions of Customer or failure of Customer to give Company adequate information or instructions. 2.3 If, subsequent to this Contract, any sale is concluded with the same Customer by fax, telegram, electronically or orally, or by any combination of these, without express reference to these Terms, these Terms shall apply unless expressly modified in writing signed by both Company and Customer. 2.4 Any statement or representation by the Company or its employees or agents upon which the Customer intends to rely must be set out in writing and signed by both parties. Any statement or representation which is not so confirmed in writing is followed or acted upon entirely at the Customer’s own risk. For the avoidance of doubt, illustrations, weights, measures, performance capabilities, application suitability information and other data set out in the sales literature of Company are statements of opinion and are provided for information only and form no part of the Contract. 2.5 All quotations shall automatically expire on the expiration date listed in the quotation, if any, but in no event later than thirty (30) days from issuance and are subject to withdrawal by written or oral notice to Customer at any time. 2.6 Verbal, telephone, fax, or email Orders will be executed at Customer’s sole risk and must be confirmed in writing received by Company within 72 hours.

If Company cancels an Order pursuant to this Section it shall have no liability whatsoever for any liabilities, losses, damages, costs or expenses whatsoever incurred, suffered or paid by Customer as a result of or in connection with such cancellation. 3. PRICES 3.1 In the supply of Goods, prices do not include the cost of Delivery or of any import or customs duties or any other applicable taxes or governmental impositions unless otherwise stated in writing by Company, which taxes, impositions and duties shall be the sole responsibility of Customer. All prices are subject to the addition of any applicable sales tax. 3.2 Company reserves the right at any time prior to Delivery, to increase the price of the Goods to reflect any increase in the cost to Company which is due to any factor beyond the control of Company (including but not limited to, any foreign exchange fluctuation, currency regulation, alteration of duties, significant increase in the costs of labor, materials or any other costs of manufacture), any change in Delivery dates, quantities or specifications for the Goods which is requested by Customer, or any delay caused by a ny instructions of Customer or failure of Customer to give Company adequate information or instructions. 4. PAYMENT 4.1 Subject to Section 4.2 below, payment of the price for the Goods is due in U.S. Dollars in cash, wire or ACH funds no later than thirty (30) days following Delivery of the Goods, unless otherwise agreed in writing. 4.2 If the Customer wrongfully fails to take Delivery of the Goods, Company shall be entitled to invoice Customer for the price at any time after Company has tendered Delivery. 4.3 No payment shall be deemed to have been received by the Company until Company has received cleared funds. 4.4 In the event of default in payment by Customer, Company shall be entitled (without prejudice to any other right or remedy it may have under these Terms or otherwise) to charge interest on a daily basis (after as well as before judgment) on any amount outstanding at the annual rate of four percent (4%) above the prime rate published by JPMorgan Chase Bank from time to time. 4.5 In the event of any dispute, Customer shall not be entitled to withhold payment of the price of the Goods or any agreed payments or to any right of set-off, deduction, counterclaim, abatement or otherwise against any payment due to Company under any Contract. 4.6 In respect of Goods sold for export, unless otherwise agreed in writing, payment shall be made (a) by irrevocable letter of c redit confirmed with a clearing bank approved by Company or (b) prior to manufacture / fabrication 4.7 Time for payment shall be of the essence of the Contract. 4.8 All payments payable to Company under the Contract shall become due immediately on its termination. 5. DELIVERY 5.1 Unless otherwise agreed in writing by Company, delivery shall be deemed to take place when the Goods are made available by Company at the Delivery Point for collection by Customer or its carrier (“Delivery”). 5.2 Any and all dates and periods specified by Company for Delivery are estimates only and do not constitute fixed times for Delivery. Delivery shall not be of the essence of the Contract and shall not be made of the essence by notice.

Company reserves the right to deliver the Goods to Customer in instalments. Where the Goods are delivered in instalments, each Delivery shall constitute a separate contract and failure by Company to deliver any one or more of the instalments in accordance with these Terms or any claim by Customer in respect of any one or more instalments shall not entitle Customer to treat the Contract as a whole as repudiated. 5.4 The date for Delivery shall in every case be dependent upon prompt receipt of all necessary information, final instructions, or approvals from the Customer. 5.5 If Customer is ordering Goods for Delivery outside of the country of manufacture by Company, such Goods may be subject to import duties and taxes which are levied when the Goods reach the specified destination. Customer will be responsible for payment of such import duties and taxes. Customer will comply with all laws and regulations of the country for which the Goods are destined, and Company will not be liable for any breach of those laws. 5.6 The Customer shall (and shall procure that its sub-contractors and agents shall): (a) observe the work rules and safety regulations of Company while on Company’s premises; and (b) strictly follow all instructions and installation materials related to the Goods and not make any alteration, modification or addition to the Goods or packaging (and any alteration of the Goods, or use of non-approved parts, products or packaging with the Goods, shall be a material breach of these Terms and voids any warranties made by Company for the Goods). 6. RISK AND TITLE 6.1 Title to the Goods will pass to Customer upon Company’s Delivery of the Goods. 6.2 Unless otherwise agreed between Company and Customer in writing, risk of damage to or loss of the Goods shall pass to Customer upon Delivery. When Goods are transported by Company’s own vehicles, Delivery shall be deemed to take place at the moment the Goods are lifted from Company’s vehicle. 6.3 No claim for Goods damaged in transit will be considered by Company unless Company used its own transport for Delivery and unless: (a) an appropriately qualified signature, e.g. “Goods received damaged, (signed)” is clearly made by Customer on the delivery note; (b) Company is advised in writing per motor carrier rules; (c) Company is advised in writing within three days of Delivery. 6.4 No allowance for claims for short deliveries will be made unless (a) notice is provided to the Company within three days of Delivery and (b) the Company is given an opportunity to verify the same. Where goods are to be stored on Customer’s site prior to use, bundled goods and crated goods should not be opened but inventoried for short deliveries as a sealed bundle or crate. Once opened, n otice and opportunity to verify any shortages must be given as provided above. 6.5 For the avoidance of doubt, where Customer collects the Goods from the Delivery Point or where a third party collects the Goods for transport to Customer, Company shall have no liability to Customer for any Goods damaged in transit. 7. WARRANTY AND LIABILITY 7.1 For and during the Warranty Period (as defined below), the Company warrants that the Goods will comply in all material respects with any specifications for the Goods agreed to in writing between Company and Customer. If no specification for the Goods has been agreed to in writing between Company and Customer, Company warrants for and during the Warranty Period that the Goods will comply in all material respects with the specifications published by Company in relation to the Goods from time to time (if any), or, in the absence of any specification (agreed or published), the Goods will be free from material defects in workmanship or materials (the “Warranty”). 7.2 THE FOREGOING WARRANTY IS IN LIEU OF AND EXCLUDES ALL OTHER WARRANTIES NOT EXPRESSLY SET FORTH HEREIN, WHETHER EXPRESS OR IMPLIED BY OPERATION OF LAW OR OTHERWISE, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. 7.3 Any claim for defect with respect to the Goods sold hereunder shall be deemed waived by Customer unless Company is notified i n writing, in the case of defects apparent on visual inspection, within sixty (60) days from Delivery, or, in the case of defects not apparent on visual inspection, within twelve (12) months from Delivery (such 60 days or 12 months, as applicable, the “Warranty Period”). All Goods claimed to be defective shall be held subject to Company’s inspection, and Company shall not be liable for the cost of any repairs performed without its express written consent. The Goods claimed to be defective may be returned prepaid to Company’s plant for inspection in accordance with return shipping instructions that Company shall furnish to Customer upon receipt of Customer’s notice of claim. If the claim is established, the Company will reimburse the Customer for all shipping costs incurred in connection with such return. 7.4 This Warranty is made to Customer and does not extend to any other person or entity and is not assignable. 7.5 This Warranty shall not apply (a) if the Goods have been subject to improper storage, accident, misuse or unauthorized modifications, alterations, or repairs, or have not been installed, operated, and maintained in accordance with procedures approved by Company, (b) to normal wear and tear, (c) to any errors, omissions or defects contained in the specifications or designs provided by Customer or (d) to any components manufactured by Customer or a third party not approved by Company. 7.6 Customer shall indemnify and keep Company indemnified in full against all and any direct, indirect or consequential liabilities (all three of which terms include without limitation loss of profit, loss of business, depletion of goodwill and like loss), losses, claims, damages, costs and expenses (including all legal and other professional expenses) awarded against or incurred or paid by Company as a result of or in connection with any breach of the Contract by Customer and death or personal injury to Company’s employees or agents while such employees or agents are on any premises of Customer in connection with the Contract. Without limiting the foregoing, Customer shall indemnify Company against all claims by any third parties for any claims, loss, damage or expense resulting from the breach by Customer of any of its obligations under these Terms, including without limitation, any modification, misuse, or unapproved alteration of, or use of non-approved components with, the Goods. 7.7 To the fullest extent permitted by law, under no circumstances will Company be liable to Customer for an amount in excess of the price paid, or to be paid, for the Goods for any claims, losses, liens, costs, liabilities, causes of action, suits, demands, judgments, obligations, fines, penalties, damages, requirements, violations, and expenses (including without limitation, attorneys’ fees, court costs, and costs of investigation) of any nature, kind, or description, whether based in contract, warranty, indemnity, or tort (including negligence and strict liability), of any person or entity, directly or indirectly, arising out of, resulting from or related to the Contract or the Goods. 8.

The monthly usage would be compared to historical data, and Rice Lake would be responsible for the difference. Now that construction is nearing completion, the gas usage for the winters of 2023-2024 and 2024-2025 were compared to historical data and the difference was found to be $15,927.00. Therefore, a credit of $15,927.00 is being issued to the City of Otsego. Please let me know if you have any questions.
