Security was a primary requirement for Mexico's new C5 building project in Guanajuato State. C5 systems serve to manage, evaluate, maintain, coordinate, organize and oversee communications, computer, control and command networks. Additionally, this government agency coordinates and oversees specific plan, program and project implementations that by law are to be carried out with regard to public-security matters in the various states. Most of the building's panels are curved, lending the structure excellent aesthetic and functional properties. With tilt-up, the fast-track project was completed in less than 11 months, including design, construction and operation. Tilt-Up met the project's security needs, as concrete provides excellent bullet resistance and complies with Mexico's requirements. Architectural appearance, concrete malleability and low maintenance cost for a government building. Tilt-up was an excellent option to reflect the architect's vision, making this the first C5 installation in Mexico to be built with the construction method.
