Building
Up or Out: Should more cities follow the lead of Ventura County
and look at high-rise buildings to accommodate growth as an
alternative to the subdivision?

Ventura County
Builds Up Instead of Out
Located
north of Los Angeles, Ventura County is synonymous with proliferating
suburbia and urban sprawl. But now, concerns over preserving
hillsides and agricultural resources coupled with stringent
regulations to control growth are sparking a high-rise building
boom.
Six buildings ranging from 15 to 46-stories are on the drawing
board and awaiting approval from the local agencies along the
Pacific Coast. At the hub of booming economic growth, the cities
of Oxnard and Port Hueneme plan to add high-rise residential,
office, and retail space in communities thus far dominated by
subdivisions.
Ventura County adds 10,000 new residents each year. Also fueling
the shift from subdivisions to high-rise living is a change
in demographic trends towards empty nesters, which favors condominium
living. Contact Attila

| Standards
Bodies Three Steps
Closer to Harmonizing Cement Specs
The American Association of State Highway and Transportation
Officials’ (AASHTO) Subcommittee on Materials and ASTM
International’s Committee C01 on Cement recently passed
ballot proposals to harmonize three of five significant differences
between the provisions of the standard specifications for
portland cement, AASHTO M 85 and ASTM C 150, published by
these organizations.
The 2007 editions of these standards will have consistent
provisions for fineness, Type II C3S content, heat
of hydration–related criteria, and use of up to 5% limestone
in portland cement. It is anticipated that revised standards
will be published in July of 2007.
These changes are the result of an ongoing focused harmonization
effort that was initiated in the summer of 2003. AASHTO M
85 and ASTM C 150 have existed as parallel standards for portland
cement since the 1940s. State departments of transportation
reference one (or sometimes both) of these standards when
specifying portland cement for concrete construction.
Consistent requirements will ultimately result in better concrete
by simplifying quality control, specifications, and production.

Study Shows U.S. Homebuyers
Unwilling to Pay for Green Features
Homebuyers are unwilling to pay more for
a home that contains green design features and environmentally
friendly materials, Architecture 2030 founder Ed Mazria said
this week in the Atlanta Journal-Constitution.
According to Mazria, although many homebuilders are adding energy
saving features and are experimenting with environmentally friendly
materials, buyers have not been willing to pay more for the
green features.
Estimates vary widely for how much green building can add to
the final price of a home, with the lower estimates at 3 to
5 percent versus the higher predictions of 10 to 15 percent.
The National Association of Home Builders and McGraw-Hill Construction
predicted recently that the number of green homes will increase
from the current level of 2 percent to 10 percent of all homes
by 2010. |

EPA Finds New
Life for Old Building Materials
Nearly 77,000 tons of concrete will be
recycled during the construction of Shops at White Oak Village,
a hotel and retail complex in Henrico County, Va. Contractors
of the former manufacturing site near Richmond plan to crush
the concrete on-site and use it for foundations, sidewalks,
and structural support.
In addition to the concrete, the project is
expected to also recycle almost 7,500 tons of aluminum, steel,
iron, copper, assorted ferrous and non-ferrous metals and
electronic equipment from the old building.
The U.S. Environmental Protection Agency
has been working with the Forest City Commercial Group to
incorporate recycling and sustainable design into the project.
Demolition of the former Viasystems building began about seven
weeks ago following an environmental investigation and selection
of a remediation plan according to EPA guidelines.

PCA
sponsors Illinois’ next Fortified Home:
PCA will host a groundbreaking on April 2, 2007, for a Fortified…for
Safer Living home in Aurora, Ill. In addition to the partnership
with the American Red Cross and the Illinois Emergency Management
Agency, PCA is working with a non-profit organization, the Joseph
Corporation, and the trades programs of three Aurora-area high
schools to construct a precast concrete home. The panels will
be constructed using Dukane Precast's double-wall system. Erection
of nearly all the wall and ceiling panels is planned for the
ceremony.

HPC Featured in South Dakota: PCA's Shri Bhidé
was a guest speaker at the 43rd Annual Concrete Conference held
last week in Rapid City, S.D. The co-sponsors of the conference
included: Dakota Chapter of ACI; GCC, Dakota Cement; and North
Central Cement Promotion Association. Shri’s presentations
highlighted the benefits of high performance and ultra-high
performance concrete for bridge applications.

Transit Fares Well
Should more cities follow the lead of Phoenix and turn to
light rail transit as an alternative to expanding the capacity
of streets and expressways?
Notable Comments:
"Rail is nice but usually empty. There is not a mass
transit system on this planet that breaks even or makes money.
All it does is sucks funds from the transportation system
and does not pay into the system."
"We must also assure that sufficient roadway capacity
exists to efficiently allow commerce to move. Freight mobility
is critical to global competition as well as clean air."
"Cities should be designed having quality of life in
mind instead of just cars and traffic. Remember that the U.S.
is the fattest country in the world. We should encourage people
to walk, not drive."
"Nobody is going to ride this stupid train. It goes too
slow, makes a lot of stops, and will be a traffic burden.
It will be faster to sit in street traffic than to take that
route."
"Increasing capacity for more automobiles and trucks
just encourages wasteful energy consumption and doesn't provide
any long term improvements."
"Construction cost of the system would probably be cheaper
than the cost of land purchases for street rights-of-way,
imminent domain processes, easements, etc. Also the problems
of traffic congestion would only be deferred, not solved,
and air pollution from exhaust fumes would only increase.
The only reservation I have about it is whether the public
would utilize it once it is in place."
