Mutual of Omaha's Midtown Crossing
Tops One Million Square Feet

Omaha's Midtown Crossing at Turner Park—a $250-million mixed-use development project including seven buildings and more than one million square feet of space—will be structural concrete.

PCA's Amy Trygestad and local allies worked with structural engineers Nielsen-Baumert Engineering on a plan for post-tensioned concrete construction, which reduces both cost and construction time over steel options.

Developers Mutual of Omaha and ECI Investment Advisors say work will begin immediately for a 2009 occupancy. Part of Destination Midtown area rejuvenation, Midtown Crossing at Turner Park comprises seven buildings with approximately 200,000 square feet of leasable space for restaurants, retailers and entertainment venues as well as 600 condominium and apartment units and the addition of parking for approximately 2,200 vehicles. The site is near Mutual of Omaha headquarters.

In addition to Midtown Crossing, Trygestad is involved in several other major projects in Omaha. WallStreet Tower, a 32-story, $122-million luxury condominium project, will be the third tallest building in Omaha. In the planning stages is a new office building for the Federal Bureau of Investigation with design critera that includes protection from progressive collapse, blast resistance, and LEED certification.

Call for Entries: 2007 PCA Education Foundation
Research Fellowships

PCA's Education Foundation is seeking nominations for outstanding graduate students in the fields of engineering and the physical sciences for the 2007 PCA Education Foundation Research Fellowships. Each year the Foundation awards students working on projects related to cement manufacturing, concrete technology, residential, public works, masonry, and engineered structures.

Honorees receive a $20,000 stipend, paid to the university, to cover tuition and other related educational expenses. Applications are due January 15, 2007.

The fellowships are open to any student completing studies towards a masters or doctoral degree from an institution of higher education within Canada or the United States that is accredited by a regional or national agency. The applicant must be pursuing graduate study in an engineering, science, material science, or architectural program.

Cement Consumption by User Group Available
PCA has released the Third Quarter 2006 Survey of Portland Cement Consumption by User Group report.

The report includes a historical perspective of North American portland cement consumption by sixteen user groups for the past six years. It also includes information on cement kiln dust (CKD) for soil-cement paving and waste solidification/stabilization projects.

Cement consumption for the third quarter of 2006 was 34.18 million tons, down 3% from third quarter 2005. Ready-mixed concrete was the largest consumer with 72.4% of the total, followed by brick and block (4.1%), and streets and highways contractors (3.3%).

PCA "Greenovates"
PCA exhibited at the National Building Museum’s Greenovation: An Expo for the Home, on Nov. 18 in Washington, D.C. The expo was part of the museum’s Green House exhibition, which PCA sponsored. Aimed at the consumer, the show focused on remodeling and renovation.

PCA was one of 28 participating organizations including the U.S. Department of Energy, EPA, National Association of Home Remodeling Industry, American Society of Landscape Architects, and the Energy and Environmental Building Association.

Tom Evans, promotion director of the Maryland Ready Mixed Concrete Association, staffed the PCA booth and spoke to nearly 1500 people about the environmental benefits of cement and concrete products. Booth visitors received literature on concrete homes, architectural finishes, and pervious concrete and were encouraged to visit www.concretehomes.com to learn more about how concrete fits into green building.


Study: Pyramids are Really Concrete
The New York Times reports that a scientist from Drexel University has concluded that the Great Pyramids of Egypt were made of cast concrete blocks rather than quarried and cut limestone.

Materials engineering professor Michel W. Barsoum found evidence that Egyptians used concrete blocks for the massive monuments beginning at around 2550 B.C., making the pyramids the earliest and most enduring example of concrete construction.


The study was published in The Journal of the American Ceramic Society.

Holcim Plant Wins National Corporate Citizenship Award
The Council of State Governments (CSG) recently recognized the Holcim (US) plant in Theodore, Ala., as the winner of the 2006 CSG Associates Award for corporate citizenship for the plant’s ongoing commitment to helping the community rebuild after Hurricane Katrina.

The CSG award was presented to Holcim Plant Manager Joe McFalls on Dec. 2 by Oklahoma Governor Brad Henry during a ceremony in Phoenix, Ariz. During remarks, Gov. Henry highlighted two specific projects Holcim undertook to help the community rebuild. The first was a rural health clinic in Bayou, La., that serves low-income residents in the Theodore community. The clinic was destroyed by the hurricane and after being rebuilt, suffered another blow when it burned down the day before it was scheduled to re-open.

Holcim officials also coordinated with the local Habitat for Humanity office to support efforts to build new homes for those displaced by Hurricane Katrina. Holcim, in partnership with other local industries, arranged to have the concrete donated for all 11 Habitat for Humanity houses being built in the Belwood subdivision in Theodore. Holcim employees also provided volunteer labor on the building projects.

The CSG Associates Award is given in recognition of an association's private sector members who have demonstrated exemplary partnerships with the states, the communities they serve and CSG.

Make Affordable Housing Part of Development Package

The lack of affordable housing is becoming a crisis in cities like Los Angeles, where more than 88% of residents cannot afford to buy a median-priced home. What's the answer?
Responses (percent)

  • Mandate affordable housing units as a condition for new development 38 (62.30%)
  • Finance affordable housing programs locally with initiatives such as bond issues 9 (14.75%)
  • Step up private efforts through organizations such as Habitat for Humanity 8 (13.11%)
  • Increase federal involvement with programs such as HUD 6 (9.84%)

Notable Comments

"Let the market work. If it is too expensive to live in L.A., then people will move to areas where they can afford to live."

"The true problem is that housing costs have increased faster than salaries. Sending jobs to India and China don't help this. High interest rates make it worse."

"The North American housing market is going through what every maturing market goes thru eventually. It is time that home owners start to realize that living in a big house in the 'burbs is not environmentally friendly nor sustainable, therefore more people will have to live in higher density condos that are closer to where they work and having a smaller foot print on this world."
