T " <br />3.. <br />Municipal Builders, Enc.] <br />December 27, 2022 <br />Mrs. Nancy Zeigler <br />AE2S <br />6901 E Fish Lake Rd. <br />Suite 3184 <br />Maple Grove, MN 55369 <br />Re: Mounds View WTP 1 Rehabilitation <br />CPR 16 Alternate ABB VFD <br />Dear Mrs. Zeigler, <br />In response to the further delay in shipment for the Eaton VFD's we have put together the costs <br />to cancel the Eaton order and change to an ABB VFD instead. This includes the increased cost <br />of the VFD as well as the costs associated with the modifications required to add all of the <br />equipment to the drive and fit it into the space available on site. <br />The new VFDs have approximately a 6 week lead time as long as they do not get allocated prior <br />to an order being placed. The ethernet cards are currently backordered and would be installed in <br />the field when they arrive. The ABB enclosures are larger than the Eaton ones. Well 1 does not <br />have enough wall space so the VFD will need to hang off the corner of the wall about 10". There <br />is a panel around the corner that sticks out about the same so it is not much more of an <br />inconvenience. A picture is attached for a better idea what that will look like. Well 3 has enough <br />room for the larger VFD. <br />Siihrnntract- <br />Killmer Electric $49,234.07 <br />Contractor Fee: $2,461.71 <br />Total Cost: $51,695.78 <br />Please review the pricing above and approve in the form of a change order. <br />Sincerely, <br />Nathan Neubauer <br />Project Manager <br />Municipal Builders, Inc. <br />7900 Old Viking Blvd Nowthen, MN Phone: (763) 421-8790 Fax: (763) 421-1028 <br />
