A commitment to quality, the environment and prevention.
At COS we are aware of the challenge posed by the climate impact of the construction sector. That is why we have made the environment part of our day-to-day decisions, building it into the quality controls carried out while construction processes are executed, in line with UNE-EN ISO 9001.
Our environmental management covers measures such as waste management, recovery of construction and demolition waste, eco-design, life-cycle analysis and the circular economy, among others. All of it is backed by an Environmental Management System based on UNE-EN ISO 14001, certified and externally audited on our sites and at our permanent workplaces.
The health and safety of our team is a priority on every project. We build occupational risk prevention into every stage of the works, from planning to execution. We invest in continuous training for our people, early identification of risks and constant improvement of working procedures, in line with UNE-EN ISO 45001.
