3 4 Wk Sess Conf & Educ Ctr HOKMEMORANDUM
February 28, 2002
TO:
The Honorable Mayor and City Council Members
FROM: Michael C. Van Milligen, City Manager
SUBJECT: March 4 Work Session
Attached is the latest information provided by HOK Venue, the consultants designing
the Mississippi River National Education and Conference Center. Included in this
information is revised elevation drawings, floor level plans, revised schedule and cost
estimates. As indicated on the cost estimate summary sheet, the project is at 90%
design development and shows a base bid for construction of 26,896,200 or -0.06%
less than City resources without our contingency. This means the project is currently
$15,000 under budget, The City has a construction contingency for this project of
$1,376,042, and there is a design contingency of $1 million. Included in this base bid is
the construction of the River Room, which was previously identified as an alternate.
Also included is an additional cost of a structural slab foundation due to the poor soil
conditions found on site. The cost summary also identifies the list of add alternates in
order of priority.
As previously mentioned, this project is expected to be complete by November 2003.
To meet this schedule the project must be broken into two bidding phases. The first
phase would occur in April 2002 and would include site improvements and deep
foundations. The second bid package would occur in July 2002 for all other
construction. In order to meet this schedule we need to reach consensus on the design
so that HOK Venue may proceed to the construction document phase of the project.
I respectfully request Mayor and City Council approval of the design for the Mississippi
River National Education and Conference Center.

MEMORANDUM
February 28, 2002
TO:
FROM:
SUBJECT:
Michael C. Van Milligen, City Manager
Mississippi River National Education and Conference Center Worksession
Introduction
The purpose of this memorandum is to provide information on the design of the
Mississippi River National Education and Conference Center for the March 4 City
Council worksession.
Background
Since August 2001, city staff began to work with a consultant team to develop a design
for the new conference and education center. This Center is part of the City's
commitment to the Vision Iowa funding for the America's River project and the City's
Development Agreement with Platinum Hospitality. This process included the
workgroup called for in the Platinum Hospitality Development Agreement, which
includes:
- Jerry Enzler, Dubuque County Historical Society
- Sue Czeshinski, Convention and Visitor's Bureau, Dubuque Area Chamber of
Commerce
- Jim Rix, Platinum Hospitality Group
- Rick Dickinson, Greater Dubuque Development Corporation
- Bill Baum, Economic Development Director
- Laura Carstens, Planning Services Manager
- Pauline Joyce, Administrative Services Manager
- Cindy Steinhauser, Assistant City Manager (Facilitator)
In addition, the following participated in the design process:
- David Hockenberry, Platinum Hospitality
- Rich Russell, Building Services
- Pam Myhre, Economic Development
- Mike Koch, Public Works
This process has included design charrettes, regularly scheduled workgroup meetings,
presentation to Port of Dubuque property owner meetings as well as two worksessions
with City Council held on November 5 and December 17. This process has also
included a two-day value engineering session that included representatives from HOK
Venue and their sub-consultants as well as project manager for the City, Jim Kolf and
field inspector for the City, Bill Schmelling, both of the Durrant Group and their cost
estimators.
Discussion
Attached are the latest elevation drawings, floor level plans and cost estimations for the
Center. This information reflects changes to the design to create a more efficient facility
from a construction and management perspective. Some of the changes includes:
- Reducing the exhibit hall span from 180' to 150' while retaining the 30,000
square foot exhibit space;
- Reconfiguration of"back of house" services such as kitchen,
mechanical/electrical room and storage areas;
- Factory primed trusses for exhibit hall in lieu of a second finish to the exhibit
hall ceiling;
- Use of decorative metal mesh panels for railing around river room;
- Include operational wall for exhibit hall as a bid alternate
- Use of colored concrete on plaza adjacent to riverwalk versus concrete tile;
- Minor reduction of plaza adjacent to riverwalk to provide natural slope versus
retaining walls;
- Include fountain, enhanced landscaping and hardscape as bid alternates;
- Include Dubuque plaza on west entrance as a bid alternate;
- Modification of spine height and width to improve proportion to building; and
Modification of prefunction space adjacent to meeting rooms.
The use of native limestone, glass and metal in the design are meant to emulate the
bluffs of Dubuque and the reflective nature of the river. This design retains important
elements such as the 30,000 square foot exhibit hall with carpet, 12,000 square foot
ballroom, 12,000 square foot of meeting space as well as plenty of prefunction space
and exterior plaza space to provide for informal gatherings as well as social functions.
These spaces are accessible via an elevator, escalator and stairs. This design also
retains the signature architectural element of the facility, the glass spine, which peaks to
a height of 59' at its easternmost point (73' from ground level) and provides panoramic
views of the Mississippi as well as views of the bluffs of Dubuque and the gold dome of
the courthouse. Also shown of the elevations are outdoor "party" plazas on the east
and west elevations, a covered drop-off area for vehicles, 365 surface and underground
parking stalls as well as a connection to the Hotel Waterpark.
Currently the project is near completion of design development. As indicated on the
attached budget information, revised estimates show the base bid at $26,896,200 or
0.06% underthe City's budget without our contingency of $1,376,042. Included in this
base bid is the additional cost of a structural slab foundation under the exhibit hall due
to the soil conditions as well as a $1,000,000 design/bid contingency as recommended
by HOK Venue and project manager Jim Kolf. The chart below provides information on
the various stages of cost estimation and the design/bid contingency allocated to each
phase. It is important to note that schematic design is the first phase and costs
associated with the eady designs are preliminary. As the project moves from schematic
design to design development the costs provide a truer reflection of actual costs and
thus the contingency becomes reduced.
Date Estimate Contingency

10/24/01 $26,946,994 $2,355,506

Prior to the bidding process, we will continue to have discussions with HOK Venue and
Jim Kolf on incorporating a contractor completion incentive similar to those included in
the contracts for Town Clock Plaza and the Fengler Street bridge.
Also attached is a revised construction schedule as provided by Jim Kolf. You will recall
from previous correspondence that this project will be broken into two bidding phases.
The first bid package, scheduled for April 2002, will be for site improvements and a
foundation package. The second bid package will be for all other construction and will
be bid in July 2002 with a completion date of late November 2003.
Action,
The requested action is to provide this information to City Council and to request their
acceptance of the design in order to proceed to the construction document and bidding
phase.
