West 32nd Street Detension Basin ProjectTHE CITY OF DUBUQUE Masterpiece on the Mississippi Dubuque All-American City 2007 TO: The Honorable Mayor and City Council Members FROM: Michael C. Van Milligen, City Manager SUBJECT: West 32nd Street Detention Basin Project (CIP 7201357) DATE: May 14, 2008 Sealed bids were received on March 20, 2008, for the West 32nd Street Detention Basin Project. Tschiggfrie Excavating submitted the low base bid in the amount of $1,560,371.25. This amount is 14.31% under the engineer's estimate of probable cost. One of the alternate bids is for installation of a fence. The two reasonable options to consider are a vinyl split-rail fence for $28,600 or a black vinyl-coated chain link fence for $33,000. City Engineer Gus Psihoyos recommends award of the contract to the low bidder, Tschiggfrie Excavating. If the black vinyl-coated chain link fence is chosen, the total construction amount awarded to Tschiggfrie Excavating would be $1,593,371.25. If the vinyl split-rail fence option is chosen, the total construction amount awarded to Tschiggfrie Excavating would be $1,588,971.25. I concur with the recommendation and respectfully recommend Mayor and City Council approval of the bid award, with whichever fence option the Mayor and City Council prefers. Michael C. Van Milligen MCVM/jh Attachment cc: Barry Lindahl, City Attorney Cindy Steinhauser, Assistant City Manager Gus Psihoyos, City Engineer THE CITY OF DUBUQUE Masterpiece on the Mississippi Dubuque All-American City 2007 TO: Michael C. Van Milligen, City Manag FROM: Gus Psihoyos, City Engineer SUBJECT: West 32nd Street Detention Basin Project (CIP 7201357) DATE: May 14, 2008 INTRODUCTION The enclosed resolution authorizes the award of the construction contract for the West 32"d Street Detention Basin Project. DISCUSSION Construction of the West 32nd Street Detention Basin involves the excavation of approximately 105,000 cubic yards of soil of which about 75,000 cubic yards must be hauled from the site. Work includes the construction of an earthen embankment and installation of a large diameter storm sewer: 96 feet of 108-inch diameter, 190 feet of 96-inch diameter, and 235 feet of 66-inch diameter RCP. It also includes the installation of 328 feet of 24-inch diameter DIP sanitary sewer. Finally, it includes the construction of a twin, 9-foot wide by 8-foot high box culvert to replace the bridge just east of Wildwood. BID RESULTS Base Bid Sealed bids were received on the project on March 20, 2008. Tschiggfrie Excavating of Dubuque, Iowa submitted the low base bid in the amount of $1,560,371.25. This amount is 14.31 % under the engineer's estimate of probable cost. A summary of the base bid proposals received are as follows: Contractor Name Total Bid Tschiggfrie Excavating $1,560,371.25 Portzen Construction $2,082,365.00 WC Stewart Construction $2,085,104.46 Connolly Construction $2,389,183.40 Alternate Bids - Pond Aerator: Since the bids for the item were more than 38% higher than the estimated cost ($18,000), Engineering staff does not recommend that an aerator be installed with the construction contract for the West 32"d Street Detention Basin project. - Fence: Due to the eventual presence of a wet pond, consideration was given to include a fence as another means to address real or perceived public safety concerns. It is important to note that there are several design considerations that have been factored in to the proposed wet basin that should serve to greatly reduce these concerns. They are as follows: o The plans for the entire basin include restoring native habitat through planting of native prairie plants. These plants form dense groupings with tall stalks, sometimes four to six feet tall. In addition to making passage through the vegetation difficult, it will also serve to visually screen the basin. Some communities, which make fencing around detention ponds mandatory, will allow this type of vegetation as an alternative to fencing. o The basin side slopes will be constructed no steeper than a 25% grade, both above and below the water surface. At a point approximately one foot below the water surface, an aquatic safety shelf will be constructed at a 10% slope providing an even more gradual depth transition. This safety shelf will extend 10 feet into the basin before resuming a 4:1 slope. This safety shelf will allow a person to gradually perceive increasing depth of water and will eliminate the sudden drop-off condition that may put a person in over their head without warning. The presence of the aquatic safety shelf will create a narrow band of aquatic vegetation sticking above the waterline around the perimeter of the basin. This vegetation will be very dense and generally unpleasant to walk through, discouraging people from entering the basin. A perimeter fence would demark a clear boundary where public access is not desired and may be much more aesthetically pleasing, blending into the landscape architecture incorporated into the design. Perimeter fencing may also be augmented with warning signs describing the West 32nd Street Stormwater Management Facility as an area subject to flooding. The three fence alternatives include: Figure 1--a white, split-rail style vinyl fence Figure 2--a black, vinyl- coated chain link fence (not shown), Figure 3--a wrought iron hoop railing that has installed on top of several City retaining walls (not shown). Figure 1. The photograph above shows a maintenance-free vinyl split-rain style fence surrounding a stormwater detention pond with native vegetation similar to that planned for the West 32nd Street stormwater Management Facility. A summary of the bid alternates for fencing is as follows: Fence Type Estimate Bid Split Rail $ 44,000.00 $ 28,600.00 Black Vinyl-Coated Chain Link 48,400.00 33,000.00 Wrought Iron 253,000.00 176,000.00 Engineering staff recommends adding the installation of a fence to the construction contract for the West 32"d Street Detention Basin project and requests direction on installing a split rail fence or a black vinyl-coated chain link fence. RECOMMENDATION recommend that the contract be awarded to Tschiggfrie Excavating in the base bid amount of $1,560,371.25. If the black, vinyl-coated chain link fence is chosen, the total construction amount awarded to Tschiggfrie Excavating would be $1,593,371.25 ($1,560,371.35 + $33,000). If split rail fence option, the total construction amount awarded to Tschiggfrie Excavating would be $1,588,971.25.
