Our Vision & Values

Our vision is to be the leading provider of utility & highway infrastructure services.

With an embedded culture of sustainability and innovation, and with a consistent focus on delivering service excellence, we strive to continuously improve our performance aiming for exceptional quality, right first time solutions, safely, on time, every time.

We work collaboratively with our clients, partners, highway authorities and others, adopting a one team, one goal approach to all our projects. We have built this approach around six key values:

  • Trusting: doing what we say
  • Communicating: in an honest and respectful manner
  • Listening: with an open mind
  • Working together equally: regardless of status.
  • Being the best we can: with a can do, will do attitude
  • Responsibility: taking ownership

We call this The SQS Way. We complete over 100,000 jobs every year with around 99% achieving defect free status.

‘SIMPLY  BETTER’  the SQS Way

Our vision is to be the industry leader. That doesn’t mean we will be the biggest, but to achieve our vision it does mean we must be the best! Being the best at everything we do. Putting our ‘One Team, One Goal’ culture and values into practice, every job, every day! ‘SIMPLY  BETTER’ – it’s the SQS way.
