Message from our CEO
The development of Spain in the 1970s allowed companies such as CONTROL Y APLICACIONES (CAE) to participate in the assembly and start-up of new industrial facilities. The teams involved in commissioning process remained at the plant, constituting the first maintenance team.
The growth and consolidation of this activity led to the creation of Mantenimiento y Montajes Industriales, MASA, in Tarragona on 22 November 1976.
Our dedication to Client Service from the beginning, combined with the Experience of our personnel and continuous Growth by incorporating new activities, has enabled the building of a solid Group of national and international companies which are part of COBRA INDUSTRIAL SERVICES.
We celebrate our 50th anniversary year by extending our gratitude:
- To our clients for their trust
- To our suppliers for their collaboration
- And, above all, to our personnel for their daily effort and commitment.
Reaching fifty years is a major SUCCESS.
Congratulations to all!

Policies
CORPORATE COMPLIANCE PROGRAM
Commitment to ethics and transparency
Compliance (Corporate Compliance Programme)
The organisation is highly committed to complying with the highest standards of corporate ethics, and has had a Corporate Compliance Programme in place since 31 March 2018, which is reviewed periodically by external advisors of recognised prestige and which includes, in an organised manner, the actions implemented to establish an environment of prevention, detection and early risk management. This Programme has a specific focus on the fight against infringements, both criminal and anti-competitive, among other matters, guaranteeing the highest level of integrity in all its business practices.
The company adheres to VINCI's standards, which set out the principles shared by all employees and business partners and whose core values are defined in the following 5 reference documents:
- The Code of Ethics and Conduct, which sets out all the principles of business ethics to be applied in different circumstances and in all countries of operation.
- It is used in conjunction with the Anti-Corruption Code of Conduct, which includes rules on the prevention of all acts of corruption, in particular by identifying risks in business processes and defining the behaviours to be avoided.
- The Human Rights Guide, which summarizes possible risks and their implications for companies, and defines a common set of guidelines on how to address issues related to human rights. These guidelines are based on the principles of the Universal Declaration of Human Rights (UDHR), on the 8 fundamental conventions of the International Labour Organization (ILO), and on the OECD Guidelines for Multinational Enterprises.
- The Declaration on the Essential and Fundamental Actions in Occupational Health and Safety, which reflects the shared commitment to achieving the “Zero Accidents” objective. The declaration is the result of a constructive and regular social dialogue. As part of a continuous improvement policy, it states that progress can only be made with all employees through the promotion of a safety culture.
- The environmental guidelines, which provide a framework designed to minimize the risks and impacts of activities on the environment. All companies must follow these guidelines so that actions and procedures can be improved and adapted in order to protect and preserve the environment in all places where operations take place. Each subsidiary is responsible for ensuring that business partners make similar efforts throughout the entire life cycle of a project.
The Corporate Compliance Programme consists of the following documents:
