DATE: November 8, 2010
City Engineer Gus Psihoyos is recommending acceptance of the construction contract
for the Green Alley Project (15 — 16 between Washington & Elm Streets), as
completed by Connolly Construction, Inc. in the final contract amount of $164,306.81,
which is a 6.7% increase from the original contract of $154,046.52. The cost increase
was due to additional watermain valve replacement needed to properly shut down the
watermain during the project. Also, the storm sewer line in 15 Street had to be
repaired.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

The enclosed resolution provides for the acceptance of the construction contract for the
Green Alley Project (15 — 16 between Washington & Elm Streets).
BACKGROUND
The Green Alley Project (15 — 16 between Washington & EIm Streets) included:
— Reconstruction of the alley pavement surface with interlocking concrete pavers
between Washington & Elm Streets, from 15 Street to 16 Street.
— Watermain reconstruction.
— Replacement of seven (7) lead water services with copper.
— New concrete sanitary manholes in the alley and on 15 and 16 Streets.
Since the project was funded utilizing Community Development Block Grant, American
Recovery & Reinvestment Act funds (CDBG /ARRA), no assessments were levied for
the project.
The Green Alley Project (15 — 16 between Washington & EIm Streets) was
completed by Connolly Construction, Inc. of Peosta, Iowa, in the final contract amount
of $164,306.81, which is a 6.7% increase from the original contract of $154,046.52.
The cost increase was due to additional watermain valve replacement needed to
properly shut down the watermain during the project. Also the storm sewer line in 15
Street had to be repaired.
RECOMMENDATION
I recommend that the City Council accept the improvements and establish the final
contract at $164,306.81 for the Green Alley Project (15 — 16 between Washington &
Elm Streets).
