Frequently Asked Questions

What is geotechnical engineering and why is it important?

Geotechnical engineering focuses on soil, rock, and ground conditions that affect the stability and safety of structures. It is critical for designing foundations, retaining walls, pavements, and slopes. Without proper geotechnical investigations, developments face risks such as cracking, settlement, or failure. Learn more from Geoscience Australia.

Do I need a geotechnical report for council approval?

Yes. Most residential, commercial, and infrastructure projects require a geotechnical or soil report to obtain Development Applications (DA) or Construction Certificates (CC). These reports demonstrate compliance with the National Construction Code (NCC) and local planning requirements via the NSW Planning Portal.

What Australian Standards apply to geotechnical engineering?

Our designs and reports comply with key standards, including:

These standards ensure compliance, safety, and long-term performance.

How do geotechnical engineers support foundation design?

Geotechnical engineers analyse soil strength, settlement, and groundwater conditions to recommend the most suitable foundation type. At Apex, we work closely with our Structural Engineering Consultants to design safe and cost-effective solutions for residential, commercial, and civil projects.

Can geotechnical engineers help with slope stability and landslip risks?

Yes. We provide slope stability modelling and design remediation measures to prevent erosion or collapse. Our assessments follow best practices from the Australian Geomechanics Society and are essential for developments on sloping or unstable ground.

Do you provide geotechnical services for infrastructure projects?

Absolutely. Apex delivers site investigations, pavement design, and earthworks support for roads, bridges, and subdivisions. These services are often integrated with our Civil & Infrastructure Engineering and Stormwater Management teams to ensure seamless project delivery.

What Our Clients Say

Our reputation is built on successful project delivery and long-term partnerships. Here’s what clients say about working with Apex Civil Engineers:

Samir was of really great service with a professional approach and can do attitude. I was impressed with APEX CE’s prompt service and quick delivery time. Look forward to our next business opportunity in the near future.

I recently used the APEX CE group for some of my Construction Certificate documents (Stormwater, Parking and Erosion/Sediments Plans). They were professional and easy to deal with, had a quick and timely turnaround and was very competitive in the quoting stage. I will definitely recommend Samir and his team for future projects.

I needed to install a detention pit as part of a Stormwater condition of my DA application but Samir proposed two rainwater tanks as a more feasible and cost effective alternative. I found Samir to be extremely reliable, knowledgeable and efficient. He promptly inspected my home, then drew the OSR Plans which were immediately approved by Ryde City Council. I would recommend Samir’s service to anyone.

I found Samir apart from having a professional approach to the building work to be a like able person to deal with Thanks again Samir Martin.
