geotechnical engineering
Every successful project starts from the ground up. Smart Alliances provides comprehensive geotechnical engineering services, including penetrometer soil testing (PT’s), site investigations, ground assessments, liquefaction assessments or comments and detailed reporting to determine land suitability and foundation requirements.
With extensive experience across Marlborough, Kaikōura, and the Marlborough Sounds, our team specialises in challenging sites, including steep terrain, coastal environments, and liquefaction-prone areas. We deliver practical geotechnical solutions for subdivisions, new builds, foundation designs and complex developments, offering services such as CPT testing coordination, slope stability assessments, retaining walls, fresh and wastewater designs, and coastal engineering advice.
Combining geotechnical, civil, structural, architecture and planning expertise, we help clients confidently navigate site constraints and achieve safe, compliant, and cost-effective project outcomes
Understanding Ground Conditions for Successful Development
Geotechnical engineering is critical to ensuring developments are built on safe and suitable ground. Our team investigates subsurface conditions, identifies geotechnical hazards, and provides practical recommendations that support efficient design and construction outcomes.
We consider:
Soil and ground conditions
Foundation requirements
Liquefaction susceptibility
Slope stability and land instability risks
Groundwater influences
Coastal and erosion hazards
Earthworks suitability and site development constraints
Compliance with local authority and building requirements
By identifying potential ground-related issues early, we help reduce project risks, minimise costly delays, and ensure developments proceed with confidence.
Our team provides expert engineering support for:
Penetrometer testing (PTs)
Geotechnical site investigations
Foundation design recommendations
Liquefaction assessments and geotechnical comments
Subdivision and land development assessments
CPT testing coordination
Slope stability assessments
Retaining wall design support
Earthworks investigations and reporting
Freshwater and wastewater design
Coastal and marine engineering advice
Construction monitoring and geotechnical certification
Flood damage and slip assessments
With extensive experience throughout Marlborough, Kaikōura, and the Marlborough Sounds, our team specialises in challenging environments, including steep terrain, coastal sites, and liquefaction-prone areas. We deliver practical geotechnical solutions that support safe, resilient, and successful developments from concept through to completion.
