completing an improvement project in 2015 to remove the plywood sheet and extend the 73"A-RCP storm sewer to Lake Ramsey. Staff was concerned that if the plywood sheet failed again,a portion of Bunker Lake Boulevard could buckle. Staff had estimated costs for this work at$175,000 and proposed to pay for the work using City Stormwater Utility Funds. Following discussion,the Public Works Committee recommended that the proposed improvements not be completed until the outlet is needed for a specific purpose,thereby potentially reducing or eliminating City costs. Such a purpose could include new development,in which case the developer may fund all or a portion of the work, or the reconstruction of Bunker Lake Boulevard,in which case project costs may be significantly reduced due to being constructed with a larger project. A copy of the June 16,2015 Public Works committee meeting minutes are attached. Staff had prepared preliminary plans and specifications for the proposed improvements,along with an engineer's estimate,prior to the June 16, 2015 Public Works Committee meeting. Then following City Council approvals in 2016 related to development of the COR Three North Commons parcel, staff completed final plans and specifications as attached to this case. As shown in the plans,the storm sewer outlet is not proposed to be down-sized to reduce construction costs as discussed in 2006 since doing so would remove the ability to provide future drainage for areas north of RTC 10 th Addition through the outlet,plus it is not considered to be good engineering practice to reduce pipe sizes downstream. Notification: Advertisements for bids were published in the City's official newspaper,the Anoka County Union Herald, and in Finance and Commerce, on July 29th and August 5th. Observations/Alternatives: Observations: This is the second of two cases being considered by Council this evening relative to development of the COR Three North Commons parcel. Development of this parcel requires advance construction of the proposed storm sewer outlet. It is also important to recognize that future development of other undeveloped parcels in this area of The COR will also require the proposed storm sewer outlet to be constructed in advance of development. Once Council accepts bids and awards a construction contract,work may commence as soon as contract documents are executed and a Notice to Proceed is issued,which is anticipated to occur on or shortly after September 1st. Construction of the proposed improvements is anticipated to take 5 weeks or less to complete, depending on weather and availability of materials. This should allow the storm sewer outlet to be operational by early October, allowing unimpeded development of the COR Three North Commons parcel and other parcels in this area of The COR. A total of six bids were received and were publicly opened at 10 am Friday,August 19th. All bids were competitive, and were checked for errors and omissions,of which none were found. The bid results are as follows. CONTRACTOR TOTAL BID Kuechle Underground Inc. $108,802.15 Dryden Excavating $109,185.10 Douglas-Kerr Underground $111,653.43 Penn Contracting, Inc. $119,550.50 Dave Perkins Contracting Inc. $121,962.00 orthdale Construction Company,Inc. $129,995.96 Engineer's Estimate $122,534.50 The bid of Kuechle Underground Inc. of Kimball,Minnesota,in the amount of$108,802.15 for the total bid for construction of said improvements in accordance with the approved plans and specifications and advertisement for bids, is the lowest responsible bidder.
