Interventions relating to environmental externalities

1. Promotion of energy efficiency 

  • Specifically through the use of LED lighting technology on a large scale.

2. Monitoring of the environmental impact

  • Monitoring of the environmental impact of infrastructures under construction or already built. Conducting of environmental impact studies (EIS), which will be used to define minimisation measures and monitoring plans for a number of environmental descriptors.

Water Resources

Measures implemented:

  • installation of tailing ponds, associated with the respective macrophyte beds, constituting a "naturalised" system that is very efficient in capturing pollutants transported in dissolved state or in fine particles, which is a pioneering system in Portugal.

Noise Pollution

Monitoring of noise and implementation of measures such as:

  • use of permeable sound-absorbing paving;

  • installation of noise barriers.

Ecological Systems 

protection of fauna and flora, especially endangered species.
Measures implemented:

  • implementation of "naturalised" wildlife corridors, attenuating the barrier effect of our infrastructures.

  • replanting of protected tree species (e.g. cork oaks and holm oaks) as a compensatory measure.

3. Integration of the roads in the landscape, specifically through:

development of a Landscape Integration Project per sub-stretch of motorway, for the entire area surrounding our road infrastructures.
selection of native species so that the infrastructures can be quickly and harmoniously integrated into their surroundings;
planting of tree barriers that serve as a protective visual barrier for the houses nearest the motorways.

Our contribution to the promotion of a socially responsible operation takes the form of a series of initiatives in the following areas:

  • Social Support – This consists of direct support for private charities, collaboration on volunteer and fund-raising projects, the establishment of protocols, and campaigns to promote healthy lifestyles and disease prevention, among other initiatives;

  • Road Safety –This consists of a series of services and activities, such as round-the-clock travel assistance  , the monitoring and continuous control of traffic conditions, the monitoring of accidents and the assessment of road conditions;

  • Heritage and archaeology – Noteworthy in this respect is the funding offered for archaeological digs to be carried out, as part of our construction activity;

  • Research and Development – This involves collaboration with universities and higher education establishments on research or development projects and on work placement programmes for students.

We believe that an organisation's greatest assets are its people. This is why we place such importance on the professional development of our team and on our investment in their qualification and training. We recognise that every employee's commitment to their on-the-job performance will impact our teams and the Organisation as a whole. We take great care in ensuring that every individual team member knows what is expected of them and that their own expectations are also taken into consideration, so that everyone can feel involved sharing the Organisation's growth.

Initiatives undertaken in this respect include:

  • Annual Training Plan

  • Promotion of Safety in the Workplace

  • Promotion of a healthy lifestyle and disease prevention

  • Sporting and cultural team activities, as a means of fostering internal cohesion

In order for our ambitions in terms of quality and innovation to be a reality, we strive to establish the most suitable and fruitful partnerships in every field. Where research is concerned, our association and joint work with universities and other highly-prestigious and technically-competent partners allows us to fully exploit our commitment to innovation and quality, as well as our determination to stand out from the crowd in the industry where we operate.

In this respect, we highlight our most recent project - SustIMS, developed jointly with the University of Minho and the Universidade Nova de Lisboa: the development of a sustainable management platform for road infrastructures to assist  and support decision-making in the management of the infrastructures, minimising the environmental, social and economic costs associated with their life cycles.

The platform enables the coherent and sustainable management of the main aspects of an infrastructure, including bridges, pavements, slopes, retaining walls, and telematics equipment. Through this integrated management, it will be possible to improve the quality of the information available about the infrastructure at any given moment, improve forecasts of future performance, and make better decisions in terms of conservation and rehabilitation.
