We have reviewed all the Bids received for the Work and have enclosed a copy of the Bid Tabulation and the low bid for your information and reference. Paragraph 18.07 of the Instructions to Bidders provides that the Contract should be awarded to the Bidder whose submission best serves the Buyer's interests. Although minor irregularities exist, this procurement process was somewhat atypical, as equipment suppliers submitted bids directly through Quest rather than through a general contractor. The recommended Bidder recognized the potential for confusion, addressed it effectively, and demonstrated a clear and thorough understanding of the project scope. Transformers The low bid was submitted by Tech Electric for Eaton/Cooper transformers in the amount of $412,200. The Tech Electric Eaton/Cooper lead time is 114 weeks after their submittal is approved, causing the equipment to arrive after the required July 16, 2027 delivery date. The second low bid was submitted by NEXT Electric for Eaton/Cooper transformers in the amount of $469,428. The NEXT Electric Eaton/Cooper lead time is 114 weeks after their submittal is approved, causing the equipment to arrive after the required July 16, 2027 delivery date. The third low bid was submitted Tech Electric for Van Tran transformers in the amount of $487,800. The Van Tran lead time is 30 weeks, which satisfies the required July 16, 2027 delivery date. Donohue recommends purchasing the Van Tran transformers in accordance with the Tech Electric bid. Switcheear The low bid was submitted by T&D Products for Avail — Power Grid Solutions switchgear in the amount of $219,920. The second low bid was submitted by Tech Electric for S&C switchgear in the amount of $296,930. The T&D bid included clarifications are listed below. 1. The switchgear is Canadian Standards Association (CSA) listed, not Underwriters Laboratories (UL) listed. Donohue discussed CSA listing with the Department of Safety and Professional Services (DSPS). DSPS defers to OSHA for Nationally Recognized Testing Laboratories (NRTL); OSHA recognizes CSA as a NRTL meaning DSPS allows CSA certification. 2. 120/240 volt control power for the switchgear is necessary. 3. 125 volt DC control power for the switchgear is necessary. 4. Protective relaying testing and setting adjustment is required to be completed by a third party. Mr. James Rabe Page 2 1 June 16, 2025 To address clarifications 2, 3, and 4 from T&D Products, additional equipment will be required, which will increase the installation cost. Additionally, the proposed switchgear will rely on third -party microprocessor -based relays for proper functionality. In the engineer's opinion, incorporating these items will add approximately $25,000 to the switchgear installation cost. Per Instruction to Bidders, Paragraph 18.07, the Buyer may select any bid deemed in its best interest, considering both cost and non -economic factors submitted. Furthermore, Section 26 13 00, Paragraph 1.03.A, specifies that manufacturers must have experience producing switchgear similar to that required for this Project, with a demonstrated record of successful in-service performance. The equipment manufacturer in the T&D Products bid (Avail) failed to provide evidence of a comparable installation. The second low bid, which was submitted by Tech Electric, includes S&C switchgear that derives control power within the switchgear and utilizes single phase protection with devices manufactured by S&C. S&C has numerous medium voltage (15 and 24.9 kilovolt) installations at water and wastewater facilities in Wisconsin, many within the WPS and W.E. Energies territories. Some of those installations are listed below. A. Milwaukee MSD, Jones Island WRF, 15 kV, W.E. Energies B. Milwaukee MSD, South Shore WRF, 24.9 kV, W.E. Energies C. Brookfield WWTP, 24.9 kV, W.E. Energies D. Sheboygan WTP, 15 kV E. La Crosse WWTP, 15 kV F. Kenosha WTP, 24.9 kV, W.E. Energies G. Kenosha WWTP, 24.9 kV, W.E. Energies H. North Shore Water Commission, 34.5 kV, W.E. Energies I. Milwaukee Water Works, 24.9 kV, W.E. Energies J. Fort Atkinson WWTP, 24.9 kV K. Oak Creek WTP, W.E. Energies L. Waukesha WWTP, 24.9 kV, W.E. Energies M. Racine WTP, 24.9 kV, W.E. Energies S&C offered a $23,000 deduct related to the type of voltage sensors used within the switchgear. Donohue has confirmed that WPS would accept the proposed sensors. Factoring in the added $25,000 for Avail switchgear installation and the $23,000 deduct for the S&C switchgear voltage sensors, the difference in price of $77,000 becomes $29,010. �M�nufacturer ON Bich Pace, MINSIR RMIUM, Lost Award AillstnntAd]usted NOW Prrce„ Avail failed to provide evidence that they comply with Section 2613 00, Paragraph 1.03.A and, therefore, failed to confirm compliance with the specifications. Given [1] the failure of Avail to demonstrate specification compliance, [2] the simplicity of the S&C switchgear, [3] the numerous S&C installations at nearby water/wastewater facilities, and [4] previous S&C acceptance from the electric utility (WPS; parent company W.E. Energies), Donohue recommends purchasing S&C switchgear in accordance with the Tech Electric bid. Mr. James Rabe Page 3 1 June 16, 2025 Recommendation Donohue recommends purchasing Van Tran transformers and S&C switchgear, both from Tech Electric, with a total price of $784,730 and pursue the S&C switchgear deduct after award. We are presenting this evaluation for your review and consideration.
