8.2. SR 03-02-2015 �j Elk = - Request for Action River To Item Number Mayor and City Council 8.2 Agenda Section Meeting Date Prepared by General Business March 2, 2015 Justin Femrite, P.E., City Engineer Item Description Reviewed by Wastewater Treatment Facility Improvements Tim Simon, Finance Director Change Order Matt Stevens, Chief Operator Reviewed by Cal Portner, City Administrator Action Requested Approve, by motion, Change Order #1 for the Wastewater Treatment Facility Improvement project. Background/Discussion The attached change order and letter from Rice Lake Construction Group detail the request for change to the contract completion date and price. Our project manager, Seth Peterson, and staff have negotiated with Rice Lake Construction Group to limit the time extension and contract increase to a justified amount. The contract time extension will not cause us to miss any timelines for compliance with our discharge permit. Staff supports the recommendation of our project manager to approve Option 1,which adds 138 days to the contract time and $259,991.59 to the contract price. Financial Impact The approved project budget including construction, engineering, testing, utility relocations, and bond issuance at time of bid award was $18,037,050. The change order would increase this project budget by up to $259,991.59 or 1.4 percent. There is the potential that if no other large unforeseen conditions arise, some of this increase will be absorbed in the contingencies already built into the contract. In 2016, near the end of the contract,we will re-evaluate the final costs to determine the appropriate final bond sale amount (if necessary) and adjust the final funding sources to assure that rates will accommodate the increase.

Group ENGINEER: Bolton&Menk, Inc. You are directed to make the following changes in the Contract Documents. Description: The project was bid in June 2014 and Notice to Proceed was not received until October 2014. This delay was due to the MPCA not having the NPDES permit and EAW approved. Plan and specification approval was not granted until October 28,2014. At that time construction could start. Shortly after construction started a black cinder material was found in the excavation area and this material required special disposal. There were time delays due to testing of the material and determining locations where the material could be disposed. Due to these delays the contractor is requesting additional costs and time extension. We recommend Option 1 as outlined in Rice Lake's letter. Reason for Change Order: Delay in obtaining plan and specification approval,the NPDES permit and EAW from the MPCA. Also,black cinder material was discovered in the excavation area and required special disposal.

Delay Start of Delay End of Delay Number of Calendar Days Delayed Notice to Proceed 8/3/14 10/6/14 64 MPCA Permit 10/6/14 10/28/14 22 Black Cinder Material 10/28/14 12/19/14 52 Total Days 138 Delayed Following typical construction project timelines, Rice Lake bid this project anticipating receiving the Notice to Proceed around 8/1/14. We would then have been able to start the major concrete work on the Aeration Basin shortly after. Rice Lake has been delayed a total of 138 days due to the issues with the Notice to Proceed, MPCA Permit and the Black Cinder Material found onsite. Rice Lake has the following options to move forward with: 1) With the construction of the Aeration Basin now into the winter months, winter conditions costs will be a major factor for the concrete work. However, at bid time we planned on finishing one half of the Aeration Basin last fall, and the second half this spring. By planning on constructing the Aeration Basin this way, we were able to minimize our winter conditions 22360 County Road 12 costs. Now that we are into the winter months, Rice Lake is requesting to PO Box 517 be compensated for winter condition costs in the amount of$259,991.59 if Deerwood, MN 56444 PH 218-546-5519 work on the Aeration Basin must continue this winter. We would also FX 218-546-7016 require a time extension of 138 calendar days for the delays we have experienced to date. Attached is a summary of the additional costs for option 1. 2) Our other option is to wait until spring to start the work on the Aeration Basin. However, we would then run into price escalations on concrete, rebar material, rebar install and labor. Rice Lake would also incur additional overhead costs from the time extension that would be required. The total cost would be $294,760.81, and we would also require a time extension of 245 calendar days. Please note we would continue work on the Biosolids Building No. 2 and also the RAS/WAS wet well, and would cover the winter conditions costs on these structures. Attached is a breakout of the costs for option 2. Please let us know how you would like to proceed. If you have any questions, or require additional information, do not hesitate to contact us.
