This change order includes revisions to the scope of work for the pavement rehabilitation. The existing pavement depths encountered in the field were significantly greater than what was indicated on the soil boring report. The greater depth of pavement required revising the pavement recondition from a bituminous reclamation to a mill and overlay. The attached Change Order 2 includes the details for the revised quantities and additional quantities necessary to change the scope of work to a mill and overlay. Change Order 2 reduces the contract amount by ($71,598.25) resulting in a revised contract amount of $533,591.41. We recommend City Council make a motion to approve Change Order No. 2. Please call me at 612-597-7140 if you have any questions or concerns regarding this change order. Sincerely, BOLTON & MENK, INC. Ryan J. Goodman, P.E.
