To keep ourselves ahead, we employ highly qualified people for our works and the equipment necessary for the technological control. Due to the diversity of the working areas, the company prepares a tactical planning for each work, defining critical items to be controlled. There is still the commitment to the Work Safety objectives, part of its quality plan.

The management of the safety system is based on rigid controls, according to the requirement of the PPRA, PCMAT and PCMSO legal programs in all the planning development phases, control and continuous evaluation of the execution of the projects.

We provide continuous campaigns on safety and medicine so that our employees have the necessary knowledge in a tangible and simple manner.

Cesbe seeks excellence in Safety, Medicine and Health. With the efforts of the field teams and support from the managers of the projects, we have obtained excellent results that guarantee our employees a safe, healthy and productive work environment.


We are a company with 76 years of history in the engineering world, but we are by no means accommodated. We seek to reinvent ourselves daily and foster critical and innovative thinking.

We are proud of our history. We know that we only got here because of people's dedication and collaboration. We continue to prepare Cesbe for the challenges of the future, stimulating an environment of learning, collaboration and transformation, in which people feel stimulated and, above all, respected. So we hope to strengthen and contribute to the sustainable development of society.

The commitment to respect, probity and justice contributed to the achievement of GPTW (Great Place to Work) certification. If you identify with our values, join us!
