He holds a bachelor’s degree in business from EAFIT University, Medellin, and a master’s degree in business administration with an emphasis in finance and economics from the University of Chicago.

Calle succeeds Jorge Mario Velasquez, who is replacing the retiring Jose Alberto Velez as CEO of Grupo Argos effective March 1.

Located near the Gulf Coast, the Tindall Corp. Moss Point, Miss., plant recently received ISO 9001:2008 Quality Management System certification for the design, manufacture and erection of precast/prestressed concrete structures. The five-plant producer previously attained such certification for its Atlas CTB precast concrete wind tower fabrication, and is eyeing additional ISO 9001-2008-level audits for processes at sister operations.

The audit ensures the company’s a) products, quality control systems and operations meet or exceed customer expectations, as well as applicable statutory and regulatory requirements; and, b) processes promote and advance continuous improvement.

Separately, the Tindall Texas Division has added Chris Pruitt, sales engineer, and Shane Rawson, technical sales representative. Prior to Tindall, Pruitt was a sales manager for a North American industrial manufacturer and U.S. Army Corps of Engineers project manager. He holds master’s and bachelor’s degrees in civil engineering from Clemson University and North Carolina State University.

Rawson joins Tindall with more than 15 years’ experience in structural precast and construction, negotiating major contracts and pursuing design-build opportunities focused on precast concrete methods. He will represent Tindall in the Dallas market. The Texas team serves the Southwest region with custom-designed precast/prestressed architectural or structural concrete systems for commercial, industrial, power and institutional building applications.
