Civil Engineering

Pre-planning to construction supervision

OPUS civil engineers carry projects from pre-planning and feasibility assessment through to detailed design and construction supervision. Our collaborative approach, engineering capability and coordination using 12d and DRAIN allow us to deliver a sustainable, precise and economical design.

Road geometric design Residential & commercial subdivisions Pavement design (urban & rural) Stormwater analysis Water & wastewater design Earthworks & erosion control Bridge & culvert design Retaining wall design Traffic impact assessment
02
Surveying — Land & Aerial Mapping (LiDAR)

Precision from instrument to design file

OPUS surveyors work with GNSS RTK systems and 12d software compatible with most engineering design packages, transferring survey information rapidly and accurately. Drone-based photogrammetry and LiDAR extend that precision across whole landscapes, infrastructure and construction sites.

Geotechnical Engineering

Identifying risk early, recommending what's buildable

Backed by GEO5 software and our highest geotechnical accreditations, OPUS identifies geotechnical risks early, recommends practical solutions, and works alongside clients to deliver the best possible outcome for their project.

Site investigations, inspections & site logs Geotechnical assessment — preliminary & final report Slope stability assessment Foundations engineering Retaining wall assessment & design
04
Material Laboratory & Field Testing

IANZ-accredited testing, classification & QA

Our laboratories are IANZ accredited with modern equipment to provide expert construction materials testing, classification, quality assurance, material design, data collection technology, pavement investigation and advice.
