RE: 2004 Capital Improvements Drainage Project
Briarhaven-Fieldcrest Drainage Improvements
Supplemental Agreement No. 3
Mr. Bergeron:
As you know, the field conditions on the Briarhaven drainage project required us to re-
design the sanitary sewer (L-6783) adjacent to the storm in Briarhaven. This additional
work was required due to decisions made early in the design process to avoid
replacement of the sewer if possible. This sewer design has already been completed in
order to help the City avoid remobilization costs from the contractor on site.
Attached please find a Supplemental Agreement #3 for the above described sanitary
sewer design. When possible, the unit prices from the contractor on the project were
utilized. When there were not corresponding bid items, the unit prices from the low
bidder on the Sanitary Sewer Main 238 project (designed by Dannenbaum & under
construction) were used. We respectfully request the City's consideration of this contract
amendment.
If you have any questions or require any additional information, please do not hesitate to
call.
Sincerely,
Brian D. O'Neill, P.E.
Project Manager

HEARING:
SUBJECT: Authorize Amendment No. 3 in the Amount of $10,084.00 to City Secretary Contract No.
31311, an Engineering Agreement with Dannenbaum Engineering Corporation, for the
2004 Capital Improvements Project- Bria rhaven-Fieldcrest Drainage Improvements
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute Amendment No. 3 in
the amount of$10,084.00 to City Secretary Contract No. 31311 with Dannenbaum Engineering
Corporation for the 2004 Capital Improvements Project- Briarhaven-Fieldcrest Drainage
Improvements, thereby revising the total contract amount to $183,530.95.
DISCUSSION:
The 2004 Capital Improvement Program (CIP) includes funds for the Briarhaven-Fieldcrest Drainage
Improvements Project.
A request for qualifications to provide drainage design was issued by the City in January of 2004, an
35 design consultants submitted statements of qualifications, including Dannenbaum Engineering
Corporation. Dannenbaum Engineering Corporation was selected to study the drainage in the
subject area and provide subsequent design services for drainage improvements.
On January 11, 2005, the City Council authorized the City Manager, via M&C C-20483, to execute a
engineering agreement with Dannenbaum Engineering Corporation (City Secretary Contract No.
31311), in the amount of $101,920.95, for the design of the 2004 Capital Improvements Project-
Briarhaven-Fieldcrest Drainage Improvements. This agreement was subsequently revised by two
amendments, for a total contract amount of$173,446.96, as follows:
Amendment No. 1, authorized by City Council on May 15, 2007, via M&C C-22115, in the amount
of $47,088.00 for additional design services as requested by City staff.
Amendment No. 2, administratively approved by the City on March 11, 2008, in the amount of
$24,438.00 for sub-surface utility engineering services to determine the exact location of existing
utilities.
Amendment No. 3 to the project includes design services for the preparation of plans and
specifications for relocation of sanitary sewer lateral 6783, required due to unstable soil conditions the
threatened to collapse the sanitary sewer pipeline.
Dannenbaum Engineering Corporation proposes to perform the necessary additional survey and
design work for a lump sum fee of$10,084.00. City staff considers this fee to be fair and reasonable fi
the scope of services proposed.
This project is located in COUNCIL DISTRICT 3, Mapsco 89F.
