| Heart Care in
the Heartland
Pumps Up Health-Related Construction
Heart disease continues to be the
leading cause of death in the United States—a grim statistic
that is creating a construction niche within the already booming
institutional market as the health care industry builds hospitals
focused solely on heart health.
PCA's Amy Trygestad, regional engineering manager, reports
on three such facilities in the Midwest:
St.
John's Mercy Medical Center, St. Louis, Mo. (right), a nine-story,
340,000-square-foot, $140 million cardiac care and emergency
center that opened last summer, is framed with a conventionally
reinforced flat-plate concrete system.
- Center for Advanced Heart Care at
the University of Kansas Hospital, Kansas City, Kan., opened
last week. The six-story, 238,000-square-foot, $77-million
building has a wide pan and joist concrete framing system.
- St. Luke's Mid America Heart Institute,
Kansas City, Mo., broke ground last week. The seven-story,
$145-million building will use a wide pan and joist concrete
framing system.
Trygestad cites several concrete advantages
for hospitals. A concrete frame's increased stiffness helps
control vibration—a big concern in surgical areas. Concrete's
reduced floor-to-floor height also allows for greater plenum
space, which can accommodate the extra wiring and cabling
for these high-tech facilities. A concrete frame also improves
indoor air quality because it eliminates the need for fibrous
fireproofing materials required by structural steel construction.
The Midwest projects are part of a national trend contributing
to double-digit growth in hospital and health-related construction.
In his forecast released last month, PCA chief economist Ed
Sullivan calls for hospital and institutional building to
increase by 15 percent in 2006 followed by a 6-percent gain
in 2007. Aging Baby Boomers are driving demand, says Sullivan.

World Trade Center Recommendations
Don’t Fare Well at Code Change Hearings Key
proposals stemming from the World Trade Center investigation
met with resistance at the recent International Building Code
hearing in Orlando, Fla.
The International Code Council formed the ad hoc Committee
on Terrorism Resistant Buildings to review the recommendations
in the National Institute of Standards and Technology (NIST)
World Trade Center collapse report and, if appropriate, develop
code changes to the applicable codes to implement them. The
ad hoc committee developed 14 proposals that were acted
on at the recent hearings, including two proposals affecting
concrete and cement-based products.
A change to add provisions intended to make buildings more resistant
to disproportionate collapse was recommended for disapproval.
The provisions were based on current requirements of the U.S.
Army Corps of Engineers and those in use in the United Kingdom.
The National Council of Structural Engineers Associations (NCSEA)
and others opposed the change, citing that it was too broad
in scope and would not protect against disproportionate collapse
in an attack similar to that of the World Trade Center.
A second change to require exit stair enclosure walls in buildings
greater than 420 feet in height be designed for a uniform static
lateral force of 2 psi (288 psf) was also recommended for disapproval.
The intent of the proposal was to provide some degree of protection
from the overpressure imposed on the wall due to an explosion
and could be of benefit to the cement-based products industries
since reinforced concrete and masonry walls can easily be designed
to withstand this force. However, the NCSEA pointed out that
stair shafts constructed of concrete or masonry in a building
of this height in Seismic Design Category D, E, or F would effectively
prohibit the use of a special moment frame seismic force resisting
system. Contact

| FDR
Benefits Featured in
Advertising Supplement
The characteristics and benefits of Full-Depth
Reclamation (FDR) with cement were highlighted in the October
issue of 11 McGraw Hill Construction Regional Publications.
"The Road Recycled," a 12-page insert bound into
the magazines, provides an overview of FDR and includes an
article on the use of a portable recycling machine to rehabilitate
city streets in Brownwood, Texas.
PCA produced the national section; regional promotion groups
had the option of producing a localized companion piece appearing
in only those magazines covering their region.
McGraw-Hill’s regional construction
publications reach 75,000 qualified, active construction professionals.
Both printed and PDF versions of the section are available
at no charge while supplies last.

California Portland Recognized
for Greenhouse Gas Emissions Reduction Goals
The EPA has recognized California
Portland Cement Company as one of 13 Climate Leaders who are
setting new targets for reducing their greenhouse gas (GHG)
emissions. California Portland Cement Company pledged to reduce
U.S. GHG emissions by 9 percent per production index from 2003
to 2012.
Currently the largest public corporate greenhouse gas goal-setting
program, the Climate Leaders partnership represents a broad
range of industry sectors from manufacturing to retail, small
business to multinationals, and more than $1 trillion in U.S.
revenues. The program was launched in 2002 as a key strategy
for encouraging organizations to help meet President Bush's
goal to reduce greenhouse gas intensity by 18 percent over ten
years. Starting with 11 initial companies, the industry-government
partnership has expanded to include 100 companies representing
more than 8 percent of total annual U.S. greenhouse gas emissions.

| Workshop
Targets High-Performance Concrete
PCA's Shri Bhide made a presentation on "Guide Specification
for HPC for Bridges" to more than 150 engineers attending
a workshop on high performance concrete and self consolidating
concrete held last week at Rutgers University. The workshop
was sponsored by Rutgers and the Federal Highway Administration
The presentation was based on PCA’s publication, Guide
Specification for HPC for Bridges. The document is intended
to serve as a guide for developing specifications for high
performance concrete for individual projects in all 50 states
whether produced by a ready mix supplier, a general contractor,
or in a permanent plant of a precast concrete manufacturer.

Precast Builder Recognized
by HUD: Brian Bock, vice president of sales and marketing
for Naperville,Ill.-based Mustang Construction, was recognized
by the Partnership for Advancing Technology in Housing (PATH),
a program of the U.S. Department of Housing and Urban Development,
as an innovator in durable, energy-efficient building. Bock
is one of just 30 builders, remodelers, and service providers
in the nation selected as the subject of a new case study series
on advanced homebuilding technologies that reduce energy or
water use or increase a home's storm resistance. Bock was honored
for his work promoting the benefits of precast concrete wall
panels, which result in increased durability, energy efficiency,
and safety and disaster mitigation.

Educational Seminars Presented in Vermont, Maryland: Continuing
the collaboration with FHWA, PCA on behalf of National Concrete
Bridge Council, presented two Load Resistance Factor Design
(LRFD) seminars in Timonium, Md., and Montpelier, Vt. The
seminars were co-sponsored by the Maryland Department of Transportation
and the Vermont Agency of Transportation respectively. PCA
is assisting FHWA in the implementation of the LRFD Bridge
Design Specifications throughout United States. After October
2007 all bridges receiving federal aid will have to be designed
according to those specifications.

St. Louis Group to Honor Local
Concrete Professionals: The Concrete Council of St.
Louis will hold its annual awards dinner next month, honoring
leaders of the association and industry and recognizing projects
that show the versatility and design aesthetics of concrete.
The Council’s Award of Honor will be presented to Luke
Snell, founder of the Department of Construction at Southern
Illinois University-Edwardsville, and current chair of the
ACI's International Committee.
