Graduate School of Architecture, Planning and Preservation

The Graduate School of Architecture, Planning and Preservation at Columbia University (GSAPP) offers six master’s degree programs: Master of Architecture, Master of Science Advanced Architectural Design, Architecture and Urban Design, Urban Planning, Historic Preservation, and Real Estate Development. With an enrollment of 650 students from some 55 countries, the School serves as a leading laboratory for testing new ideas about the environmental designer’s role in a global society. It cultivates an atmosphere in which all of the disciplines devoted to the built environment are invited to think diff-erently, to move beyond the highest level of professional training, opening a creative space within which the disciplines can re-think themselves in order to find new settings and new forms of professional, scholarly, technical, and ethical practice.

Department of Civil Engineering and Engineering Mechanics

The Department of Civil Engineering and Engineering Mechanics is one of nine departments in the Fu Foundation School of Engineering and Applied Science at Columbia University. Offering undergraduate programs in civil engineering and engineering mechanics, it provides students with a firm technical basis while nurturing decision-making and leadership potential. The civil engineering program, accredited by ABET, has four concentrations: structural engineering; geotechnical engineering; construction engineering and management; and water resources and environmental engineering. On the grad-uate level, the department offers pro-grams leading to the MS degree, the professional degrees of Civil Engineer or Mechanics Engineer, and the Doctor of Engineering Science (EngScD) and Doctor of Philosophy (PhD) degrees. These programs are flexible and allow for concentrations in structures, construction engineering, reliability and random processes, soil mechanics, fluid mechanics, hydrogeology, continuum mechanics,finite element methods, computational mechanics, experimental mechanics, acoustics, vibrations and dynamics, and earthquake engineering, or any com-bination thereof, such as fluidstructure interaction. www.civil.columbia.edu


Lafarge is the world leader in building materials, with its top-ranking divisions: cement, aggregates and concrete and gypsum. With 90,000 employees, Lafarge is present in 76 countries. Lafarge is the only company in the construction materials sector to be listed in the ”100 Global Most Sustainable Corporations in the World.” Lafarge has been committed to sustainable development for many years, pursuing a strategy that combines industrial know-how with performance, value creation, respect for employees and local cultures, environmental protection, and the conservation of natural resources and energy.

Lafarge is committed to developing ever more innovative products and solutions that generate value for the building industry and reduce environmental impact. To this end, the Group boasts the world’s leading building materials research facility near Lyons, France, and employs over 500 people worldwide in Research & Development. Lafarge also works in close partnership with architects, engineers, and users of its materials to push back the limits of its products and promote more sustainable construction methods that limit the environmental and human impact of construction while guaranteeing the highest quality in terms of aesthetics and durability. Over the past 15 years, the Group has taken part in a number of joint experiments and innovative architectural projects around the world. Additional information is available at www.lafarge.com


Solid States is the second in a series of conferences on architecture, engineering and materials. The series originated as a plan to collaborate; Mark Wigley, Dean, GSAPP, and Christian Meyer, Chair, Civil Engineering and Engineering Mechanics, began discussions to host a joint conference as a new model of exchange between architecture and engineering. The first conference in the series, Engineered Transparency, on glass, was held at GSAPP in September 2007. The third conference, on metals, will be held at GSAPP in autumn 2009.

Solid States: Changing Time for Concrete would not have been possible without the energy, goodwill and intellectual rigor of the conference chair, Michael Bell, who has been supported by a group of dedicated advisors and collaborators, including:

Christian Meyer, Mark Wigley, Jean-Louis Cohen, Steven Holl, Laurie Hawkinson, Juan Herreros, Jacques Lukasik, Antoine Picon, Jesse Reiser, Werner Sobek, Stephanie Tessier and Philippe Hardouin, Diana Darling and William Menking, and Benjamin Prosky, Devon Ercolano Provan, Phillip Anzalone, Mark Bearak, Adam Mercier, Dora Kelle, Victoria Benitez, Luke Bulman, Stephanie Salomon, Gabriel Bach, John Ramahlo, Lou Fernandez, Kevin Allenand the GSAPP AV crew, Rosana Rubio-Hernandez, Jesús Donaire García de la Mora, Mark Wasiuta and the GSAPP exhibitions team, and Jieun Yang.
