Utahs elegant capitol building, resting atop a grassy
knoll overlooking downtown Salt Lake City, is called the "Peoples
House" and serves as a cherished civic symbol and state historic
landmark. But the neoclassical revival-style structure, designed
by architect Richard K. A. Kletting with landscaped grounds
by Frederick Law Olmsted, was in bad shape. Dedicated in 1916,
the building was showing its age and needed a quick fix so
state officials turned to design-build and design-assist teaming
methods for a timely cure.
One of the first steps the state
took towards revitalization was to create a Capitol Preservation
Board in 1998 to oversee the 90-year-old buildings renaissance.
The following year, Salt Lake City-based Cooper Roberts Simonsen
Architects (CRSA) was tapped to prepare a report that assessed
the condition of the 320,000-sq-ft capitol, including its
soaring 165-ft-high rotunda and marble Corinthian and Ionic
columns. The results led to an ambitious $200-million multi-year
undertaking of seismic improvements, structural enhancements,
system upgrades and interior and exterior restoration that
would become the states single largest building project.

Before the upgrades could commence,
the newly formed board first had to prove its mettle. It needed
to complete two new steel-framed, granite-clad buildings totaling
185,000-sq-ft located just behind the capitol to the east
and west. The $36.6-million expansion originally was outlined
under Klettings master plan for the 40-acre site. The
four-level East/West buildings would house the states
legislature while restoration and repair work took place at
the capitol. Much was riding on the projects success.
It would be scrutinized as an example of the boards
ability to deliver a job on schedule and within budget. If
it fumbled, state legislators might have second thoughts about
funding a massive overhaul of their beloved capitol building.
"It was our first major project and it had to be perfect,"
says David H. Hart, the boards executive director. "So
we turned to design-build to limit our risk."
The board hired Houston-based 3D/I
to help it navigate the selection process. With the firms
assistance, it implemented several unique design-build measures.
For instance, instead of selecting a design-build joint venture
or integrated firm, the board provided input into both contractor
and designer selection to ensure a good fit.
The board issued a request for
proposals for a design-build construction manager in April
2001 and narrowed the seven respondents down to a qualifications-based
shortlist of three firms. The finalists were asked to prepare
a detailed management plan, including budget, schedule, methodology,
general conditions and owner interface.
The plans focused on a 100-page-plus
book of text and images created by 3D/I over a 12-month period
that outlined the boards design priorities. Much of
the document was based on Klettings original architectural
drawings, which were on loan from the state archives. Unlike
bridging documents, the book described the buildings
elaborate facade and aesthetic needs, while leaving structural,
mechanical and hardware decisions open to the team.
The board selected Jacobsen Construction
Co. Inc., Salt Lake City, under a guaranteed-maximum-price
contract. Jacobsen and the board then selected the architect.
While the board participated in the interviews, the contractor
had the final say for its design partner, Capitol Design Team.
The winning team is a consortium
of FFKR Architects; Gillies, Stransky, Brems & Smith (GSBS);
and CRSA. The design team was hired as a Jacobsen subcontractor
under a fixed-fee contract. The three Salt Lake City-based
firms divided duties for design, management and historical
accuracy among themselves to better handle the project scope
while leveraging strengths.
Stone Hunt
The newly established design-build
team immediately identified the biggest challenge as being
the stone facade fabrication and installation, accounting
for nearly 30% of the budget. The team issued subcontractor
design-assist RFPs in July 2001, but all of the submissions
were over budget. Jacobsen then hired KEPCO+, Salt Lake City,
as a consultant for $250,000 to oversee design and planning
for the stonework. KEPCO+ also could perform the work if it
could find 102,000-sq-ft of matching granite and install it
for $8.4-million.

The East/West project called for
simple box buildings with classical exteriors similar in style
to the capitol. Details included balustrades, pilasters, freestanding
columns, and entablatures.
KEPCO+ solicited fabricators worldwide
for matching granite samples. The Kletting building was constructed
from stone drawn from nearby Little Cottonwood Canyon at the
turn of the 20th century. But that quarry now is largely exhausted
and no longer can provide the large high-strength slabs needed.
KEPCO+ selected Campolonghi Italia,
Massa, Italy, as stone fabricator, then partnered with Dee
Brown Inc. (DBI), a frequent Garland, Texas-based collaborator,
to form KEPCO+DBI LLC. The Jacobsen design-assist sub installed
two thirds of the projects granite panels using galvanized
steel strongback and truss frames. The remaining stone was
handset onsite utilizing either cast-in-place concrete or
metal-stud framing. The projects other sub packages
used a traditional design-bid-build method.
To ensure project success, the
Jacobsen team created a comfortable communal environment for
promoting ideas and dialogue. That included roundtable discussions
open to all subs and suppliers plus regular weekly, monthly
and sometimes daily meetings among key players. The owner
installed a cluster of jobsite trailers, which further enhanced
decisionmaking.
Talking Freely
Jacobsen also allowed its subs,
suppliers, and designers to speak with one another, provided
it was updated by note or e-mail. Many projects have a formal
channel for responding to questions and decisions that can
alienate team members and slow progress. Jacobsen broke down
those barriers and fostered involvement.
"We tried a non-traditional approach,"
says Douglas C. Welling, Jacobsens executive vice president.
"We developed a circular organizational chart to have everybody
working from the inside out."
The practice resulted in a shared
sense of ownership that produced a genuine team atmosphere.
Everyone felt invested in the project, striving for the same
goals and same success. A further enhancement was the elimination
of liquidated damages. "Whenever damages are attached, people
begin positioning themselves for liability," says Bruce D.
Knaphus, president of KEPCO+. "It waters down the collaborative
team effort."
There were no added incentives
for the job except the possibility of more work. Although
Jacobsens two-year contract had a no shared savings
clause, it could earn $15,000 quarterly bonuses for a total
of $120,000. The owner and Jacobsen rated the firms
performance using a point system based on safety, budget,
quality and relationships. Jacobsen scored 100% each time,
securing the full bonus amount. "It worked well because it
brought us to the table to talk about the issues and take
a long-view approach," says Welling. "It really fostered a
teamwork atmosphere. We had no incentive to pad the numbers
that we were giving them."
The board also liked the approach.
The East/West expansion buildings opened in March 2004, nearly
six months faster than a traditional design-bid-build project.
The state subsequently funded the retrofit job, but chose
not to use design-build because it felt that the project was
too large for one entity. Jacobsen teamed with Hunt Construction
Group Inc., Scottsdale, Ariz., to form a 50:50 joint venture
as construction manager. Both contractors were familiar with
each other and had historical renovation experience, financial
resources and the ability to self-perform work.
The joint venture was hired in
August 2002 under a $172-million guaranteed- maximum-price
contract with opportunities to earn $380,000 in performance
bonuses, or $27,142 per quarter. "Weve been working
with the owner for two years, so we had a running start,"
Welling says. "We werent wasting time getting to know
each other. We already understood the others skill set
and expectations."

The state also hired the Capitol
Renovation Team, a joint venture of Salt Lake City-based VCBO
Architecture and Max J. Smith Architects (MSJA), with Schooley
Caldwell Associates, Columbus, Ohio, as the project architect
in the summer of 2002 under a fixed-fee contract. It has potential
quarterly performance bonuses of $8,000 during the design
phase and $2,500 in the construction phase. "We formed the
joint venture due to the three needs required of this projecthistorical
accuracy, design and management," says Robert N. Pett, principal
with MJSA Architects. "There has been a good division of labor
and everyone has been extremely cooperative. Were not
working out of three offices, but out of one office that we
share in the trailer complex. We have since moved to one part
of the trailer and the construction team has moved in enabling
us to work hand-in-glove."
Although there were surprisingly
detailed plans existing for the capitol, the design team did
exhaustive preliminary destructive testing and analysis. It
took nearly two years for it to thoroughly learn about the
building and design the project before construction began
in Sept. 2004.
The electrical, mechanical and
plumbing systems are being modernized, while the building
undergoes a seismic retrofit that involves stiffening structural
components and adding base isolators. The 283-ft-high building
must withstand a 1G horizontal force and .5G of vertical force,
with no more than 2 ft of deflection. The work required placing
4-ft-dia. rubber isolators under 290 supporting columns, measuring
30-in. sq, in the capitols basement.
In order to install the base isolators,
the loads carried by the individual columns must be transferred
to temporary columns while the main column is cut and the
isolator installed. Micropiles also are being placed around
each column footing to increase capacity from 4,500 to 6,000
lb per sq ft. A new basement slab is being poured and a 4-ft-wide,
15-ft-deep retaining wall constructed around the building
to provide for a 4-ft-wide covered perimeter excavation. It
will allow the building to sway in the event of an earthquake.
"The building frame is concrete,
the granite on the exterior is not attached to the structure
and the dome rests on the building with nothing to tie it
to the main facility. Balustrades around the roof are held
in place only with gravity," Hart says. "These [are] significant
safety issues."
The drum of the dome needs seismic
enhancement. It must be strengthened with shotcrete, which
means carefully removing and storing the rotundas 6,000-lb
chandelier and 95-ft-long, 7,000-lb support chain. The copper
domes exterior, which is partly covered in terracotta
tiles, is one of seven design-assist sub packages under Jacobsen/Hunt.
KEPCO+DBI LLC is removing, cataloging, cleaning, repairing
and replacing the domes 10,000 tiles.
When the capitol restoration is
completed, the states House of Representatives, Senate
and Governors Office will move back and the East/West
structures will be converted to office space. The undertaking,
which will require nearly 900 people onsite during the height
of construction, will finish by the summer of 2008.
The project is going well due to
lessons learned from the design-build expansion. "We learned
one of the first things to do was define the projects
most difficult elements at the outset, seeking input from
the subs and designers," Welling says. "The subs and suppliers
became really excited when we asked for their input [and this]
has made for a great team atmosphere."
