Accept Proposal and Authorize a Contract for Engineering Services Related to the Dunmore Lift Station, City Project 2019-12.docx EXECUTIVE SUMMARY City Council Regular Meeting: May 7, 2019 AGENDA ITEM: Accept Proposal and Authorize a Contract for Engineering Services Related to the Dunmore Lift Station, City Project 2019-12 AGENDA SECTION: Consent PREPARED BY: Brian Erickson, PE, Director of Public Works/City Engineer AGENDA NO. 6.h. ATTACHMENTS: WSB & Associates Proposal; Estimate of Cost Update APPROVED BY: LJM RECOMMENDED ACTION: Motion to Accept Proposal for Engineering Services for the Dunmore Lift Station, City Project 2019-12 BACKGROUND As part of the City of Rosemount’s surface water management program, stormwater lift stations have either been constructed or are planned at various locations throughout the city. Staff has worked with developers to extend infrastructure as appropriate during initial construction to reduce future impacts to existing streets and homes. As part of the Dunmore 1st Addition, Copper Creek Development, LLC (Copper Creek) constructed regional ponding for the city and received a credit toward the stormwater fees as a result of that construction. When the Dunmore 2nd Addition is constructed, the necessary force main connection will be installed and connected to existing infrastructure. The construction of this lift station will provide for planned stormwater management of high water levels in Dunmore area. In addition, this lift station is necessary to comply with concerns that MnDOT has regarding the removal and filling of stormwater ponds located in the Harmony Parkview 2nd subdivision. WSB & Associates (WSB) provided a proposal for designing and administering the Dunmore Lift Station construction project in the summer of 2018. However, since development of Dunmore 2nd was not anticipated until 2019, the design was not started. With Dunmore 2nd anticipated this construction season, staff is recommending that this project move forward with design and ultimately construction in 2019. Design for this project will be completed this spring in order to allow for construction of this lift station in the summer and fall of 2019. There is a slight increase in total cost from the 2018 proposal to account for WSB’s 2019 hourly rates. COSTS & FUNDING The funding for both the design and construction of this lift station will come from the Storm Core Fund (607). This project was unfortunately not included in the 2019 – 2028 Capital Improvement Plan; however, based the available fund balance and planned future projects; there is sufficient funding to allow this project to proceed. The following table provides an estimated total project cost breakdown. 2 It should be noted that the current working construction estimate is based on recently-constructed lift stations of similar size. As the design progresses, WSB will prepare a detailed estimate for the construction and the estimated total project cost will be adjusted accordingly. RECOMMENDATION Staff recommends that City Council approve the attached professional engineering services proposal from WSB with an updated cost estimate of $69,638.

This letter proposal outlines the services required to prepare all necessary documents to complete final design and construction administration for the Dunmore Stormwater Lift Station. PROJECT UNDERSTANDING The City desires to complete the construction of a stormwater lift station within the Dunmore development. WSB & Associates, Inc. (WSB) will work with City staff to design, bid, and provide construction administration and observation services for the Dunmore Stormwater Lift Station in accordance with the City’s Comprehensive Surface Water Management Plan, General Specifications, and Engineering Guidelines. WSB understands that development in the area will ultimately dictate the project schedule; however, it is our plan to deliver 100% plans and specifications to the City in anticipation for a Fall 2018 construction. The stormwater lift station will pump stormwater from the recently constructed regional basin 1552 to regional basin 1589. Stormwater will be pumped from the proposed wet well location through forcemain that will be installed with the Dunmore 2nd Addition Street & Utility construction and connect to existing forcemain installed with Evermoor Glendalough 7th Addition Street & Utility construction on the west edge of the Dunmore development. WSB will coordinate with the Barr Engineering for the electrical engineering design of the project. The City’s SCADA system will be modified as part of this project. The City’s SCADA system was designed and installed by In-Control, Inc. WSB will work with In-Control during the design phase to ensure compatibility with the City’s system. It is anticipated that the new SCADA equipment will be installed in a new control panel. A new antennae pole is recommended for communicating with the master SCADA system. The project scope and proposed work plan is based on our understanding of the project, discussions with City Staff, and experience on similar projects. The key components are discussed for clarification in the following paragraphs.
