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.

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.

$1,560,371.35.
If the City Council elects to install the vinyl chain link fence option, the total construction

amount awarded to Tschiggfrie Excavating would be $1,588,971.25.
