SSGS provides professional utility location services and geotechnical support for projects across Nelson and the wider Top of the South. We help identify underground services, investigate ground conditions, and support engineering and construction projects with accurate field data and practical on-site expertise.

We are based in Nelson and regularly work throughout Nelson, Tasman, Marlborough, and surrounding regions. If your project is outside these areas, contact us to discuss availability.

We work with a wide range of clients, including:

• Civil and geotechnical engineers

• Construction and earthworks contractors

• Surveyors and planners

• Property developers

• Local councils and asset owners

• Commercial and residential clients

Our services are flexible and can be tailored to suit projects of all sizes.

If you’re unsure, that’s common. We’re happy to discuss your project and recommend the most appropriate services based on your site, scope, and level of risk.

You can contact us via our website, email, or phone to discuss your project. We’ll review your requirements and provide clear advice on scope, timing, and pricing.

Availability can vary depending on workload and project complexity. For best results, we recommend getting in touch as early as possible, particularly for projects with tight timelines.

Site visit duration depends on the size, complexity, and services required. Some utility location jobs can be completed in a few hours, while geotechnical support may be ongoing throughout a project phase. We’ll provide clear expectations upfront.

You can reach us anytime via our contact page or email. We aim to respond quickly - usually within one business day.
