About us

Building with precision and technology

With over 30 years of experience in both national and international markets, we provide technical support services for civil construction and infrastructure projects, developed by Mota-Engil Engenharia and external clients.

In the field of Topography & GIS, these two areas complement each other, becoming essential for well-informed technical decision-making, enabling safer and more efficient construction processes.

We invest in continuous training of our human resources, in acquiring cutting-edge equipment and its regular calibration.

What we do

Services

We are responsible for ensuring the geometric accuracy of projects and optimising spatial management on construction sites. This includes detailed topographic surveys, precise marking on the ground of structures to be built, as well as geometric control of works execution, using state-of-the-art technologies.

The use of Geographic Information Systems (GIS) allows us to integrate and analyse georeferenced data, supporting planning, 3D modelling and infrastructure management over time.

In this context, we provide the following services:

Since 2008, we have implemented and managed a network of GNSS (Global Navigation Satellite System) stations in mainland Portugal, which make it possible to carry out high-precision topographic surveys, automate equipment and monitor soils and structures. Using systems such as GPS, GLONASS and Galileo, the network provides centimetric accuracy and supports a wide range of activities.

Using total stations or GPS equipment, we carry out all kinds of topographic surveys to calculate areas and volumes, cadastral mapping of water and sanitation networks, and inventories of structures (e.g. roads).

Whenever a detailed survey of façades, dams or large remote areas is required, we use laser scanning technology and/or the use of Unmanned Aerial Systems (UAS/Drones). These methods make it possible to collect a dense cloud of points, thus extracting a large amount of information which, once processed, significantly reduce fieldwork time.
