Sealed bids were received for the SRF Green Alley Bid Set 4 Project. City Engineer
Gus Psihoyos recommends award of the contract to the low bidder, Drew Cook and
Sons Excavating, in the amount of $162,946.75, which is 15.56% under the engineer's
estimate of probable cost.
Based on the bid results, it is hoped that the final assessments levied to property
owners will be reduced from the original estimates due to the favorable bids received.
The average assessment based on the engineers estimate, including contingency and
engineering is $938. If final costs hold with the bid results, the estimated average
assessment will be reduced to $741.
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 4 Project.
DISCUSSION
Bid Set 4 will involve the reconstruction of two alleys in the Bee Branch Watershed. The
alley locations are as follows:
• Marshall Street to Hamilton Street (Between Rhomberg Avenue and Garfield
Avenue) — 2 blocks
This project will reconstruct the fourth set of alleys for the SRF Green Alleys in the Bee
Branch Watershed. 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. The first
year of alley reconstructions include no utilities, except sewer manhole repairs where 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 that the City cost can be covered with SRF funds.
This project will have special assessments.
