# Pedro Pacheco (engineer)

Pedro Álvares Ribeiro do Carmo Pacheco (born 7 December 1967) is a Portuguese civil engineer and professor of bridges at the Engineering Faculty of Porto University. He also co-founded BERD, a bridge engineering company. Pacheco is the mentor of the organic prestressing system concept (OPS concept), based on the human muscle, used in bridge engineering worldwide.
He is responsible for the project of more than 500,000 m$^2$ of bridge and building structures, project revision of several buildings of relevant importance. He was involved as Project Manager/Consultant or Project Reviewer in Major Projects as Braga Municipal Stadium, Ponte Infante D. Henrique (Bridge with 280m span), and Casa da Música, before 2004. After 2004 involved in several Bridges Projects, Worwilde.
Also, he is a member of GPBE (Portuguese Group of Structural Concrete), (Internacional Association for Shell and Spatial Structures) and IABSE (International Association of Bridges and Structural Engineering).

## Early life

Pacheco was born in Porto, a city known for its wine, its architecture and Eiffel Bridge, the last one inspired him to pursue his formation. He started his education in Garcia da Horta High School, and he later studied Civil Engineering at FEUP (Engineering Faculty of Porto University) where, after he graduated in 1991, he achieved the Msc Degree in 1994 and the PhD Degree in 1999, all of them with distinction.
After his graduation, in 1991, he became a Partner of AFAssociados. In that project, Pacheco was involved in several structures projects, which included buildings, bridges and viaducts. He was the main responsible for more than 500.000 m2 of projects of different types.
He was responsible for preliminary design study of Braga Municipal Stadium and was involved in the constructive methods studies of Ponte Infante D. Henrique. He was a design checker of Porto's Casa da Música in Porto and project manager of several structures such as Vodafone Headquarters in Lisbon.
In 2000, Pacheco was invited to be Professor of Bridges in FEUP (Engineering Faculty of Porto University) and after that, Member of the Construction Studies Center, in 2001.
Finally, in 2003 (Portugal) he completed the concept that he had been developing in his research, the OPS Concept, and in 2004 (other 68 countries) he registered the latest discovery, now known as OPS (Organic Prestressing System). In 2006, Pacheco co-founded BERD.

## BERD

Pacheco was co-founder of BERD (Bridge, Engineering, Research & Design), where he is, nowadays, President & CEO. This organization researches, develops and applies bridge construction methods.
Founded in 2006, BERD explores the potential of OPS (Organic Prestressing System) and has a professional multi-disciplinary research and development team.
The company is involved in several projects in Brazil, United States of America, Canada, Colombia, México, Mozambique, Turquia, India and South Korea in the construction of several bridges in Spain, Belgium, Czech Republic, Slovakia, Portugal and Brazil.
BERD is one of the world top five companies in bridge engineering and construction methods.
"Their innovative machines and their technology combining active control on launching gantries have pushed the limits of the industrialized bridge construction to values unimaginable until very recent years ago." Javier Manterola
