Smart, practical engineering for residential builders
Streamline your build with practical, innovative, and client-focused solutions across soil testing, foundation design, structural engineering, building hydraulics, and compliance inspections.
What we do
Engineering services for local builders
Soil Testing
With our own NATA accredited laboratory, we deliver faster, more accurate soil testing, site classification, site investigation, and geotechnical engineering results.
Foundation Engineering
Work with specialists in custom foundation design, and get site-specific designs for your residential and commercial projects.
Structural Engineering
Partner with the residential and commercial structural engineering experts to ensure you get compliant, efficient, high-performing structures.
Inspections
We offer compliance inspection services with live updates from site so you know about any defects (and how to fix them) right away. It's the best way to minimise downtime, maximise confidence, and ensure everything is ready for handover on time.
Building Hydraulics
Partner with hydraulic engineering consultants who look at all aspects of your site, from flows and drainage to sustainability and efficiency.
Geotechnical
With fast and accurate assessments and reports, we’ve got your residential geotechnical engineering needs covered.
