Connemara Trail, City Project 2018-09 Approve Change Order 1 EXECUTIVE SUMMARY City Council Meeting: June 15, 2021 AGENDA ITEM: Connemara Trail, City Project 2018-09: AGENDA SECTION: Approve Change Order 1 Consent PREPARED BY: Brian Erickson, PE, Director of Public AGENDA NO. 6.l. Works/City Engineer ATTACHMENTS: A-1 Excavating Proposal APPROVED BY: LJM RECOMMENDED ACTION: Motion to Approve Change Order 1 for Connemara Trail, City Project 2018-09. BACKGROUND Connemara Trail, City Project 2018-09, was awarded in March 17, 2020; however, actual construction was delayed until 2021 due to workload concerns. As a result, development in the area has proceeded and extending the stormwater interceptor at this time provides efficiencies for both the City of Rosemount and the developer. Funding for the storm interceptor would be provided by trunk funds. Additionally, a revision in the sanitary sewer on the west end would provide improved service for potential future development. Also the inclusion of paving for the far eastern end of the project allows for a connection to a future street in the Emerald Isle development which will ultimately be a developer cost. DISCUSSION With the development of Emerald Isle and the anticipated future extension of Connemara Trail to the east, an extension of the stormwater interceptor to the east as part of this contract is advantageous to the city. The change would allow the city to take advantage of the existing low bid prices for this large deep interceptor. This extension would also move the interceptor past two stormwater crossings planned as nd part of Emerald Isle 2 Addition. Thus, this provides an advantage to the developer as well. Funding for this would come from the Stormwater Trunk Fund for the interceptor work and from the developer as part of their work through development. The final cost for this change order is $389,736 which is an increase of 25% from the awarded bid amount. This is a slight reduction from the attached form due to quantity reductions as noted below. The new contract amount is $1,947,199.00. C:\\Users\\jab\\AppData\\Local\\Temp\\6.l. Connemara Trail, City Project 2018-09 Approve Change Order 1_657233\\6.l.
