24. Subdivision Volume Two Allotments equal to or Allotments equal to or greater Allotments less than greater than 1 hectare than 0.25 hectare and less than 0.25 hectare 1 hectare 0.25 per allotment (minimum 5 1 per allotment of 5) 24.4.1.4. At each CPT location record must be made of: (a) a continuous profile of the subsoil to firm basement; (b) the depth to the water table; and (c) in-situ testing of all susceptible strata. 24.4.1.5. All susceptible strata must be sampled and the construction of grading curves and atterberg limit tests determined. 24.4.1.6. For allotments located more than 200m from a river, drainage channel or the Drainage Channel Network, measured from the top of the closest bank, vertical loading must be ascertained in the manner set out in (a) to (d) below: (a) At least four scala penetrometer tests must be undertaken for each allotment. (b) Each sample point must have a field value recorded, obtained in accordance with NZS 4402.6.5.3:1988, and is to be geo-referenced to survey marks. (c) The field values of the penetrometer test must be interpreted in terms of kilo Pascals (kPa) and the basis for such interpretation defined. (d) At least one inspection pit must be constructed for every 3 allotments to confirm subsoil properties. The inspection pit must be geo- referenced and must include the logged soil profile. 24.4.1.7. Unless the recorded field soil strength from the scala penetrometer tests referred to in Standard 24.4.1.6 is at least 300 kPa at a depth of at least 0.3m below the soffit of the proposed foundations, the construction of a dwelling or other habitable building on the allotment will be required to have specific foundation design. A consent notice will be imposed on the allotment recording this requirement. 24.4.1.8. Where the field results are less than 300 kPa and scala penetrometer driving refusal occurs at 2m or more in depth, then the performance requirements shall be: (a) An Ultimate Limit State Settlement to be not greater than 100mm; and (b) A Service Limit State settlement not greater than 50mm. 24.4.1.9. Where a Standard Penetrometer Test (SPT) count result is less than 12 (corrected in accordance with best practice), and depth to sediments achieving an SPT > 12 is greater than 2m, then the performance requirements are: (a) An Ultimate Limit State Settlement to be not greater than 100mm; and (b) A Service Limit State settlement to be not greater than 50mm. Matters over which the Council has restricted its discretion: 24.4.1.10. The matters set out in 24.3.1.9 to 24.3.1.26. 24 – 16
