MEMORANDUM
November 30, 2005
FROM:
Michael C. Van Milligen, City Manao
Gus Psihoyos, City Engineer Jj .
TO:
SUBJECT:
Mullen Road Sanitary Sewer Reconstruction Project, from Asbury Road to
Hillcrest Road
(CIP 7101298/310243)
INTRODUCTION
The enclosed resolutions provide for the acceptance of the construction contract for the
Mullen Road Sanitary Sewer Reconstruction Project, from Asbury Road to Hillcrest
Road.
BACKGROUND
The Mullen Road Sanitary Sewer Reconstruction Project, from Asbury Road to Hillcrest
Road involved the installation of approximately 433 feet of eight-inch sanitary sewer on
Mullen Road. The sanitary sewer was completely redesigned to direct the sanitary
sewer flow from Asbury Road to Hillcrest Road. Also, the private sewer laterals were
reconstructed at the City's expense to allow for the redesign.
DISCUSSION
The Mullen Road Sanitary Sewer Reconstruction Project, from Asbury Road to Hillcrest
Road has been completed by Drew Cook & Sons Excavating, Inc. of Dubuque, Iowa, in
the final contract amount of $57,074.72, which is a 14.19% increase from the original
contract amount of $49,982.85.
The primary reason for contract overage ($10,600 over the original estimate) was the
expense of additional lime backfill due to poor soil conditions in the trench.
RECOMMENDATION
I recommend that the City Council accept the improvements and establish the final
contract at $57,074.72.
BUDGET IMPACT
The project cost summary for the Mullen Road Sanitary Sewer Reconstruction Project,
from Asbury Road to Hillcrest Road is as follows:
Award Final
Construction Contract
Contingency
Miscellaneous Costs (Lateral Relocation)
Construction Engineering & Inspection
$49,982.85
5,809.21
o
9.585.21
$65,377.27
Total Project Cost
$57,074.72
o
3,675.00
$17.785.00
$78,534.72
The increased construction engineering and inspection was attributed to the complete
redesign of the sanitary sewer gravity system. This redesign necessitated the evaluation
and determination of each private lateral location. Although the construction engineering
and inspection amount increased, it led to an overall project cost savings of over
$38,000.
The project will be funded with the Fiscal Year 2006 Sanitary Sewer Construction Fund
appropriation in the amount of $117,000.
ACTION TO BE TAKEN
The City Council is requested to adopt the attached resolutions accepting the
improvement and establishing the final construction cost for the Mullen Road Sanitary
Sewer Reconstruction Project, from Asbury Road to Hillcrest Road.
Prepared by Todd Irwin, Engineering Assistant
cc: Dawn Lang, Budget Director
John Klostermann, Operations & Maintenance Supervisor
