Respect. (from the lat. respectu) n. 1. respect; 2. consideration; high regard; 3. deference; compliance; veneration; 4. honour; worship; 5. relation; refererence...

We believe that everyone should be respected for their work, for their attitudes, opinions and options.

Rigor. (from the lat. rigore) n. 1. harshness; strength; 2.fig., severity; punctuality; accuracy.

There is no "more or less levelled", "more or less upright”, "more or less clean" or "more or less safe", but rather “levelled”, "upright”, "clean” and “safe". The rigour is reflected in our procedures, in time and in the rules to follow. In the light of moral and principles, being severe means being rigorous.

Passion. (from the lat. passione) n. 1. intense and usually violent feeling (affection, joy, hate, etc.) which hinders the exercise of impartial logic; 2. derived from a feeling; 3. great predilection; 4. partiality; 5. great grief; immense suffering...

Under the sign of passion – a text of the Portuguese poet Regina Guimarães – is our icon. Passion is to reveal great enthusiasm for something, favourable encouragement or opposite to something.
It is the sensibility transmitted by an architect or engineer through work.
Passion is the dedication to a project. Passion is a state of warm soul.

Loyalty. (from the lat. legalitate) n. the quality of being loyal; fidelity; sincerity.

Respect for the principles and rules that guide the honour and probity. Faithfulness to commitments and agreements undertaken, staunch character.
To remain loyal to the business partners because we depend on them and they depend on us.
Being trustworthy for being loyal.

Solidarity. (from the lat. solidare) n. 1. the quality of being solidary; 2. reciprocal responsibility among the members of a group, namely social, professional, etc.; 3. sense of sharing another’s suffering.

Being solidary is being a friend, offering our hand with genuine generosity and bringing joy and human warmth to those who, somehow, are marginalized. Being solidary is being more human. A solidary company is recognized as a fair and non-selfish company. A solidary company is a preferred choice in business. It is a more competitive company. Volunteering is a vehicle to solidarity. It is modern, fair, cultured, friend, it is a noble gesture of moral elevation.

Courage. (from the lat. coraticum) n. 1. bravery facing danger; intrepidity; to have audacity; 2. moral force before a suffering or setback; 3. [fig.] to input energy when performing a difficult task; perseverance...

Courage is essential in our life. Courage to face less pleasant situations when complex issues come up, not expecting random resolutions.
It is a value that we must highlight as opposed to the fearful, cowardly and laziness.
The courage to react to criticism not with an attitude of demotivation or sadness, but rather to search for the means and the action to overcome its own reason. This kind of courage, which is also an intellectual courage, is highly recommended.

Ambition. (from the lat. ambitione) n. 1. vehement desire of wealth, honours or glories; 2. expectation about the future; aspiration; 3. lust; greed…

Vehement desire to achieve a particular goal. Ambition not to resign ourselves. Ambition to take the best potential from ourselves. Ambition to deserve ourselves. Ambition to be athletes in our top-level competitive jobs. Ambition to beat our brands. Ambition to get the best deals with the maximum value, due to the high levels of proficiency and efficiency.

Good Taste. (from the lat. gustu) n. 1. ability to appreciate aesthetic value or standards of something; 2. elegance, refinement, aesthetic sense; 5. particular touch given by an artist to his works.

We decided to build the company's economic foundations under a cultured, cosmopolitan and cool image. Because it is a charming state of being. Good taste because we are sustainable and we respect the planet. Good taste because we are sensitive. Good taste just because.

Responsibility. (from the lat respondere) n. the trait of being answerable to someone for something or being responsible for one's conduct; a form of trustworthiness.

We must be certain that, before a choice, we chose what is best for both of us and not just the best for each one. Each employee is responsible for his negotiated activity and co-responsible if the co-worker does not fulfil his own task, thus preventing the common goal. A team is a set of individuals - is a whole. In the business game, as in social or family contexts, everyone must comply with their own relative position and we shall not permit that one of ours fails to be in our team.

As a product of a generation, we inherited the values of respect, rigour, passion, loyalty, solidarity, courage, ambition, good taste and responsibility.

Almost everything can be solved, even in moments of extreme stress, due to this desire and obsession to comply with our identity.

Whatever we might not get, we will win by means of restlessness, a sort of intellectual unhappiness which pursues us and raise us up against the adversities. Looking for this intense need of knowledge, we are able to create value in business areas where the competition requires sophistication, a distinctive quality only accessible for those who feel comfortable where they are not (as the Portuguese singer António Variações sang).

We operate in the sense of being authors of our own business narrative. We like independence and we love freedom.

A great part of the business that we execute is created by us and we will continue to fight to surprise and to carry on.

We have five business areas well defined in our strategic map: Engineering & Construction, Environment, Renewable Energy, Telecommunications and Ventures.

Each business area has a net contribution to the other ones: it is a supply chain, setting up a reciprocal help.

The networking and the symmetrical communication have one-way and it is not open to negotiation.

Within the scope of construction we are moving towards the sense of understanding what will be consumed; and in the light of time we realized that we gained the knowledge that we never had before, in the certainty that, in future, what we know today will be a little less tomorrow – what we built cannot be lost and what we have to win needs more knowledge.
