Geotechnical investigation and assessment, including foundation recommendations, is carried out in accordance with Ministry of Business Innovation and Employment (MBIE) guidelines.
The report is intended for submission to support a building consent application, confirm foundatiion design and provide a PS1.
The scope of works undertaken by Babbage comprises the following;
• A desk study of publicly available information, principally held on the New Zealand Geotechnical Database (NZGD) and from Environment Canterbury (ECan)
• A fieldwork investigation comprising shallow hand auger borings (HA) and Scala penetrometer tests (SP)
• Assessment of the ground conditions, including groundwater levels, beneath each lighting tower
• Assessment of suitable foundation options for the lighting towers
• Evaluation of geotechnical parameters for the purpose of foundation design including
determination of available bearing capacity
• Liquefaction assessment
• Foundation settlement analysis
