What we’re all about?

We are a dynamic company that adapts quickly to market needs and aims to create a company culture that encourages professional growth and development. GCS employs staff who share this vision and who are assured in the knowledge that creativity, drive and their own standards of personal excellence are only limited by how far and fast they can move.

Our Core Values:

  • Honesty
  • Trust
  • Commitment
  • Treat others with dignity and respect
  • Walk the talk (quality, standards, ethics, professionalism, morals, and integrity)


GCS continues to invest in the recruitment and development of graduates with a view of creating a talent pipeline of bright young talent with the aim of filling scarce roles within the organisation.

GCS has partnered with the National Research Foundation and Water Research Commission in order to assist students in obtaining work place experience and to promote and support their research initiatives. Since 2017 we have had two students that have successfully completed the one year NRF Internship and have been appointed as GIS Technicians. We will continue with this initiative and have appointed another two NRF interns in 2018 within our Environmental Unit.
