TEST JG was founded in 1990 in Barcelona, within the group of JG INGENIEROS. We are an engineering company with experience, young and dynamic spirit, with professionals from the sector with liberal and independent mentality whose main purpose is the person and, therefore, considers work as a means, success as a derivative and the result must be shared by everyone.

We are a company that works to solve problems. We specialize in Commissioning, Facility Management Consulting, Training and Personnel Selection. In addition, our IT team has developed MantTest.net, software for the integral management of the operation of buildings and facilities.

We are characterized by the versatility of our technicians and the ability to adapt to any situation or context. Faithful to our ethical and moral principles, we are a group of professionals capable of dealing with any project with enthusiasm, work, effort, and perseverance.


At the same time, we are increasingly interested in achieving and demonstrating responsible environmental action, controlling the impact of the activities, products, and services offered, taking into account their environmental policy and objectives. To maintain the milestones achieved, ensure compliance and establish a plan for continuous improvement, ISO 9001 and ISO 14001 standards are regularly arranged and certified in relation to quality management and the environment respectively. Specifically, TEST JG has the two certifications renewed in 2017.

On the other hand, the presence of our engineers in different associations linked to Facility Management, maintenance, exploitation, and energy management, allows TEST JG a global, innovative and updated vision of the latest trends for continuous improvement of their services.
