UNI-GR1 meets every need, from surveying to data processing

Every construction job is different. Whether you lay a new road or reconstruct an existing one, work on soil remediation, or are in the business of sewerage – every job has its own identity and characteristics. What to think of working with multiple parties in a job-specific partnership, relying on others to prepare the job for you, and those tight budgets and planning we all know too well. Know you can always trust factual and recent data to give you the headstart you get moving and the motivation to keep going.

Use the possibilities of digital surveying with UNI-Complete offers with every surface you come across. Work with centimetre accurate data to prepare, execute, and evaluate every construction job you perform. 

In case you do not know yet, centimetre accurate data consists of every point, line, or polygon of a certain location. Those that already exist or the ones you want to add to that location. CM accurate data allows for detailed planning or proposals, which helps with the overall communications of a project.

Do you need to make some changes to the data or create new points, even after you left the location? You can simply survey again and add the new points, lines, or polygons to the existing information and send it to the office using UNI-Cloud.
