SUBJECT: SRF Green Alley Bid Set 3 —Year 2
(CIP 7102450)
DATE: February 20, 2015
Sealed bids were received for the SRF Green Alley Bid Set 3 —Year 2 Project. City
Engineer Gus Psihoyos recommends award of the construction contract to the low
bidder, Portzen Construction, in the amount of$1,475,768.50, which is 4.43% over the
engineer's estimate of probable cost. The higher cost is due to the confined space for
working and the depth of sewer. As a result, special assessments for residents will be
held at the preliminary assessment average of $1,252.55 for the public improvements
assessment, including engineering and contingency.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

INTRODUCTION
The enclosed resolution authorizes the award of the construction contract for the SRF
Green Alley Bid Set 3 -Year 2 Project.
DISCUSSION
Bid Set 3 - Year 2 will involve the reconstruction of seven alleys in the Bee Branch
Watershed. The alley locations are as follows:
• Alley between Ventura Dr. and Broadway St. from Pleasant View Dr. to Putnam St.
• Alley between Fulton St. and Kane St. from King St. to Monroe St.
• Alley between Jackson St. and Washington St. from 25th St. to 26th St.
• Alley between Washington St. and Elm St. from 25th St. to 26th St.
• Alley between Francis St. and Valeria St. from Kaufmann Ave. to W. 23rd St.
• Alley between Kaufmann Ave. and W. 23rd St. from Valeria St. to Francis St.
• Alley between Ashton PI. and Avoca St. from Decorah St. to Delaware St.
This project will reconstruct the third bid set of green alleys slated for year 2 in the Bee
Branch Watershed. This bid set was developed by WHKS Engineers, Planners and
Surveyors. The Engineering Department retained three private consulting firms to work on
the design and construction documents for the year 2 alleys.
The reconstruction of the alleys will include:
- Removal of the existing alley pavement
- Excavation of the subgrade to allow the placement of clean washed stone for a
storage medium
- Installation of a concrete border for the brick pavers
— Installation of concrete headers at the alley intersection with the intersecting
streets.
— Reconstruction of the pavement surface with interlocking concrete pavers
— Reconstruction of the sanitary sewer main in two alleys
— Replacement of water main valves and hydrants
— Replacement of lead water services with copper water services in two alleys
— Replacement of sanitary sewer laterals in two alleys
This project will reconstruct the alleys into green alleys. These alleys allow rainwater to
infiltrate into the pavement rather than runoff into the storm sewers. This infiltration allows
for filtering of the water and recharge back into the aquifer. Monitoring wells are also
planned to be installed so that water quality improvements can be documented.
The project construction documents will follow the Statewide Urban Design and
Specifications (SUDAS) in the development of the construction documents.
The Iowa Department of Natural Resources (IDNR) have reviewed and approved the
plans so that the City cost can be covered with SRF funds.
This project will have special assessments.
BID RESULTS

Portzen Construction of Dubuque, Iowa, submitted the low bid in the amount of
$1,475,768.50. This amount is 4.43% over the estimate of probable cost. The additional
bid price is primarily due to the higher than anticipated sanitary sewer costs. This higher
cost is due to the confined space for working and the depth of sewer. As a result, special
assessments for residents will be held at the preliminary assessment average of
$1,252.55 for the public improvements assessment, including engineering and
contingency.
