We periodically review our Quality Management System to ensure that A SMEFA remains competitive in the construction market.

Sustainability is an increasingly important theme in companies that are in the construction business. Both during and after construction, we intend that certain actions are taken to reduce environmental impact, in order to give current and future generations a higher quality of life.

At A SMEFA, the health and well-being of employees is an important factor.

As such, our priority is to give employees the proper working conditions by making available a range of tools necessary for the perfect execution of their work.
Each employee has access to their own individual equipment that is suited for the work that will be done; this includes gloves, helmets, proper footwear, among others.

At the construction sites we place proper signage and protective bars on scaffolding, and safety nets to prevent employees, tools or even materials from falling.


A SMEFA has access to the best products thanks to our partners, who follow the same line of thought and quality.
