Ground Projects

Our geotechnical engineering team provide technical expertise with quality service in the following areas;

• Geotech investigations and assessments
• Single and multi-lot subdivisions
• Slope stability assessments and remediation
• Geotechnical hazard mapping
• Landslip assessments and remedial works design
• Pre-purchase geotechnical hazard reports
• Foundation settlement and subsidence assessments
• Earthworks design and monitoring
• Soil testing, site filling testing and certification
• Foundation inspections – Auckland Council’s Producer Statement
• Retaining wall design
• Liquefaction assessments

Where reticulated wastewater disposal is not available, on-site wastewater treatment and disposal is required.

We approach our on-site wastewater disposal design wearing our geotechnical hat, so that an inter-disciplinary approach is achieved, which is increasingly a requirement of Territorial Authorities.

We provide the following services;

• On-site wastewater treatment and disposal design reports
• Well familiar with Auckland Council Technical Publication 58 (TP 55) and NZ S 1547 2012
• Wastewater hazard and constraints assessments
• Permitted Activity and Resource (Discharge) consent applications
• Pre-purchase wastewater appraisals and development advice
• Installation inspections – Auckland Council’s Producer Statement

Effectively managing stormwater can be key to maximising the development of your site, from ensuring land stability is not compromised through to protection from flooding and maximising collection for reuse in rainwater tanks. Additionally, management of stormwater is highly regulated by Councils to preserve local ecology.

We provide the following services:

• Rainwater tank design
• Detention tank design and stormwater mitigation
• Pipeline and culvert design
• Flood assessments

Trevor Banks,  Director

Trevor Banks is a Chartered Member of Engineering New Zealand (CMEngNZ, CPEng.,) and a Member of the New Zealand Geotechnical Society (NZGS). He has over 30 years’ experience in site investigations and geotechnical design in New Zealand, Australia and UK.    

Experienced in all aspects of geotechnical engineering, he has a particular focus on residential and light commercial projects, and subdivisions, including foundation design, land stability assessments and earthworks. His duties have also included landslip assessments to assist with EQC claims for natural disaster (landslip); walkover geotechnical appraisals to assist with sales or purchases of land; and assessments of geotechnical hazards or constraints at sites to assist with assessing the development potential of land.

Trevor is also well experienced in on-site wastewater (effluent) disposal design (including Auckland Council Discharge Consent applications). The geotechnical aspects of a site, and how they relate to identified wastewater disposal areas, is an important aspect of the on-site wastewater disposal design, and increasingly required by Territorial Authorities to be addressed. With Trevor’s geotechnical background a more integrated approach to the wastewater design is therefore provided.

Trevor has carried out numerous geotechnical investigations, design and reporting throughout the entire greater Auckland region, and is well familiar with the variable geology and soils. In particular, he has been involved with numerous sites throughout the West Auckland area, and in more recent years Waiheke Island.
