Design the extension of the storm sewer system of catch basins, piping, and storm sewer <br />manholes. <br />8. Prepare Larsen Parkway plan and profile roadway drawings. <br />At the present time, we are not anticipating trail/sidewalks, decorative street lighting, or <br />streetsca pe/la ndsca ping. If these features are desired, we can work with the City on our efforts <br />to include these. <br />9. Due to the amount of land disturbance we anticipate, the City and construction Contractor will <br />need to obtain a National Pollution Discharge Elimination System (NPDES) General Stormwater <br />Permit from the Minnesota Pollution Control Agency (MPCA). We will also prepare a <br />Stormwater Pollution Prevention Plan (SWPPP). <br />10. Prepare construction drawings, including typical sections, plans, profiles, details, erosion control <br />sheets, work zone traffic control sheets, and cross sections as needed. <br />11. Review a "90%" set of Plans with the City and make any necessary adjustments. <br />12. Prepare MDH and MPCA extension permits. <br />13. Prepare construction specifications. <br />14. Estimate quantities and prepare a construction cost estimate. <br />It is important to note that as with any construction, there may need to be modifications made <br />to the quantities in the field. As such, we recommend the City budget a contingency of about <br />10% of the cost estimate (adjust contingency to 10% of construction bid once we receive that). <br />15. Complete a Gopher State One Call, as required by State Law, prior to the bid. We will also <br />distribute plans to local utility company contacts. <br />16. Prepare an Advertisement for Bids and distribute plans online through QuestCDN. <br />17. Attend the Bid Opening and review bids with the City. <br />Page 2 of 5 <br />
