Precaster: Advanced Architectural Stone
The fluid, soothing design found at Louisiana’s State Museum and Sports Hall of Fame may place a visitor into a dreamlike state as they walk the winding halls and corridors. The museum overlooking historic Cane River Lake captures shapes and textures that emulate Natchitoches’ local terrain and winding rivers, fusing two seemingly incompatible venues — sports and history — with exceptional design. According to Trahan Architects, the site greatly influenced the interior design. The “fluid shapes” of the corridors, or “river channels,” are separated by structures, or “masses of land.”
Advanced Architectural Stone created more than 1,150 precast concrete panels that are supported by a custom structural steel frame beneath.

For some businesses, establishing a positive company culture can be a daunting task. While most owners recognize that promoting employee morale, fostering effective communication and efficiently meeting customer needs are all crucial to success, it can be difficult to implement a business plan that addresses these issues while simultaneously moving forward. But for Reading Rock Inc. (pronounced “Redding”), a precast concrete producer based in Cincinnati, a simple phrase serves as the foundation for a continuous dedication to excellence and progression: “Yes, we can!”

Since 1855, Butler University existed in relative obscurity as a small liberal arts school in Indianapolis. That all changed after its basketball team made recent back-to-back runs to the national championship game and put Butler on the national radar.
Despite the elevated profile, though, Butler remains rooted in its liberal arts background, and no liberal arts campus is complete without a home for the performing arts. The newly completed Howard L. Schrott Center for Arts is the pièce de résistance of Butler’s performing arts complex. And although it made ample use of many materials to achieve the right looks and acoustics, precast concrete took the leading role.
Choosing the right connection for your project hinges on many factors – from function and ease of production to constructability and surface aesthetics.

The behavior of connections used in precast concrete products greatly influences the structural integrity of the entire structure. Whether analyzing large precast concrete wall and floor panel junctions or the load transfer mechanisms used in precast concrete pavement slabs, the design and construction of the joints and connections are crucial components that ensure the stability and robustness of the structure. The overall integrity of the precast concrete structure can be substantially enhanced by minor changes in the amount, location and detailing of connections and connection hardware.

As the sustainable building movement continues to evolve, so have its architectural design possibilities. Incredible edifices are being constructed all over the world that are environmentally conscious and resource-efficient throughout their life cycles. A shining example of this trend can be found in Victory Park near downtown Dallas. The large, striated cube made of precast concrete and glass that seems to float in mid air houses the new Perot Museum of Nature and Science, and it is a breathtaking sight to see.
Opened in December 2012, a month ahead of schedule, this $185-million project was designed by Thom Mayne, a Pritzker Architecture Prize laureate. The tower, the largest part of the museum, is made up of 70,000 sq ft of precast panels; a plinth section consisting of 220 panels, or 27,000 sq ft of curved panels; and the atrium inside the tower containing 100 panels.
Recent innovations in energy efficiencies and assembly techniques for precast concrete building envelopes open the door to unimagined architectural and sustainable designs.

The influence of concrete on the modern world cannot be understated. It has formed, shaped and progressed our built environment. Its solidity, strength and durability have advanced its prevalence in the building sector.
Precast concrete in particular has advanced modern civil, structural and architectural design. It has been used in some of the world’s most iconic structures, borne of advancements and refinements in material properties and assembly techniques.
How precast concrete buildings can clean themselves and our air.
By Claude Goguen, P.E., LEED AP
No kidding. Self-cleaning buildings are a reality. Better yet, architectural precast concrete with new material technology can remove pollutants from the air while actually rinsing itself clean in the rain. Self-cleaning buildings may sound like a futuristic concept, but they do exist today, providing aesthetic, environmental and no-cost maintenance service.
Case in point: Jubilee Church in Rome, Italy
Like white sails in the wind, three large, curved walls of precast concrete adorn the south side of the Jubilee Church in Rome. One of the primary purposes of these walls is to minimize thermal peak loads inside. The large thermal mass of the concrete walls controls internal heat gain; the result is less inside temperature variation and a more efficient use of energy.
As an added benefit to the owners, these “billowing” precast concrete walls contain titanium dioxide (TiO2) to keep the appearance of the church clean, white and beautiful. The TiO2 incorporated in the concrete absorbs ultraviolet light from the sun and becomes powerfully reactive, breaking down pollutants that come in contact with the concrete surface. There you have it: a self-cleaning building!
New formulations of cement, introduced in Europe in the ’90s, can neutralize pollution. These altered cements are used in the same way as portland cement, and therefore any precast concrete structure can potentially function as a pollution fighter. But how does it work? Read More »
A new hollow-core slab technology makes use of recycled plastic spheres to offer innovative design solutions for an open floor plan at a California college.

When officials at Harvey Mudd College decided to build a new teaching and learning center, they wanted to update its 1950s look. The college leaders envisioned a sustainable structure with naturally lit open spaces that would preserve the predominant concrete architecture of the campus. The challenge was to create large open spaces in classrooms and lecture halls without the interruption of columns and beams. The project’s design-build team found the solution in BubbleDeck, a new hollow-core slab technology that allows for extensive spans of floor and ceiling without typical column supports.
Although it was the first in California and one of the first in the United States to make use of BubbleDeck technology, the product has been used successfully in Europe, Canada and Australia. The college selected the BubbleDeck technology mainly because it helped meet the school’s goals for open floor plans and sustainability with a reduced construction timeline. In addition, the BubbleDeck system offered easier construction within the tight parameters of the job site. (For a description of the technology, see the sidebar “What Is Bubbledeck?” Read More »
Computer to Construction: Technique enables mass production of custom concrete building components from digital designs.
Story by Rick Robinson, photos by Gary Meek
Like other professionals, architects have used computer-aided design (CAD) software in their work for decades. Typically, the resulting digital files are converted to hard-copy plans, which are then used to support traditional construction practices.
Researchers in the College of Architecture at the Georgia Institute of Technology are now automating some of the processes by which computer-based designs are turned into real-world entities. They’re developing techniques that fabricate building elements directly from digital designs, allowing custom concrete components to be manufactured rapidly and at low cost.
“We’re developing the research and the protocols to manufacture high-end customized architectural products economically, safely and with environmental responsibility,” said Tristan Al-Haddad, an assistant professor in the College of Architecture who is a leader in this effort. “We think this work offers opportunities for architectural creativity at a new level and with tremendously increased efficiency.” Read More »
