How We Work - Why We Are Different

We are committed to micromanaging the flow of materials, tools and information in order to secure that no time is wasted from the real source of our strength: the working crews.



We pride ourselves of doing the right thing when no one is there to notice.

However, every day we go to work, we photograph the current situation before and after we are done. There is always a digital folder with all the info of every project that is updated every day. Our clients have online access to the progress of every project, as we update everything daily.



We only employee our own people, we do not use subcontractors for the projects we undertake. So we have complete control on every aspect of our business, people and processes. This way we can be where we must be and do what has to be done immediately. No time consuming meetings, decisions between partners or any other processes that get in the way of doing immediately what needs to be done.



We use professional and specialized tools, own a van for every 4 people we employ, use GPS tracking so everyone that needs to know, knows where every employee, van or equipment is currently located in order to solidify control, integration and streamline cooperation between our teams.
