Sealed bids were received for the SRF Green Alley Bid Set 5 — Year 1 Project. City
Engineer Gus Psihoyos recommends award of the contract to the low bidder, Drew
Cook and Sons Excavating, in the amount of $139,474.50, which is 24.4% over the
estimate of probable cost. The price for concrete pavement is significantly higher for
this project compared to the previous green alley projects. The general contractors
informed the Engineering Department that costs are higher due to the lack of availability
of concrete sub -contractors and the need to account for cold weather protection later in
the season. As a result, special assessments for residents will be held at the
preliminary assessment average of $790.46, including engineering and contingency.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

(CIP 7102450)
INTRODUCTION
The enclosed resolution authorizes the award of the construction contract for the SRF
Green Alley Bid Set 5 — Year 1 Project.
DISCUSSION
Bid Set 5 — Year 1 will involve the reconstruction of two alleys in the Bee Branch
Watershed. The alley locations are as follows:
Dubuque
NI-AmerlcaCtty
'111
1l
2007 • 2012 .2013
• Alley from 24th Street to 25th Street (Between Central Avenue and White Street)
• Alley from 24th Street to 25th Street (Between White Street and Jackson Street)
This project will reconstruct the fifth set of alleys in year 1 for the SRF Green Alleys in the
Bee Branch Watershed. Currently, there are 18 alleys under contract. Of these 18 alleys,
7 alleys are complete and being used by the abutting property owners. The other 11
alleys are in the process of construction.
Additionally, 10 additional alleys were bid on August 7th. The Engineering Department
and three private consulting firms are working on the design and construction documents
for the remainder of the alleys. Additional construction bid sets will be developed in 2 to
10 alley groupings. This year's alley reconstructions include no utility construction unless
the project affects them.
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
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 the City cost can be covered with SRF funds.
This project will have special assessments.
