SITE DESCRIPTION The site is located at 6 Burnett St, Ashburton. Access to the property is via a l driveway off the south side of Burnett St. The legal description of the site is Lot DP 699 with an area of m. Figure. Screen Capture from QuickMap showing property location highlighted in black. The property has a flat contour. The existing dwelling is located in the middle of the property and is surrounded by wooden decks and gardens. A separate garage is located at the south eastern corner of the property. The building is a storied timber framed structure with unreinforced brick veneer supported on a concrete ring foundation. The structure has lightweight suspended timber floors supported on shallow concrete piles. A level survey inside the dwelling indicates it has undergone settlement of more than mm toward the south west. SITE DESCRIPTION
6--Jw-Geotech-R-69 Consulting Engineers. GEOLOGY The Institute of Geological and Nuclear Sciences Geological Map, Geology of the Aoraki Area, defines the geology of the site as river deposits (Qa and Qa); grey river alluvium, comprising gravel, sand and silt, in active floodplains (Qa) with grey river alluvium beneath plains or low-level terraces (Qa). The geology of the site is consistent with the overall geology of the Canterbury/Christchurch region. Figure. Institute of Geological and Nuclear Sciences Geology of the Aoraki Area Geological Map, showing the subject area highlighted in red.. SITE INVESTIGATIONS Recommended minimum investigations are specified in the EC Guidelines and NZGS Geotechnical Earthquake Engineering Practice Module : Guideline for the identification, assessment and mitigation of liquefaction hazards. Based on these guidelines we recommend that the minimum site investigations to confirm building suitability are: Continuous profile of the subsoil to firm basement (usually by borehole and/or CPT) Measurement of depth to water table GEOLOGY
6--Jw-Geotech-R-69 Consulting Engineers In-situ testing of all susceptible strata (usually by CPT or SPT) Sampling of all susceptible strata Grading curves for susceptible soils Atterberg limit tests for all soils.. Cone Penetration Testing Geotechnical field investigations were carried out on the th of May,. These investigations consisted of: Visual inspections and walkover. Seven cone penetration tests (CPT) to varying depths ranging from.7m to 6.m below the existing ground level The locations of all cone penetration tests are shown on the site plan attached as Appendix.... Subsoil CPT results have been analysed with results attached in Appendix and. Results of the soil behaviour plots show alternating layers of Silty CLAY, SILT and Sandy SILT down to approximately.-6m below ground. Some CPT tests (CPTs 6 & 7) show sensitive fine grained material, interpreted as organics (peat), at a depth of between and.6m. All of the CPTs refused on a competent layer interpreted as SAND and/or GRAVEL. The groundwater table ranges from.7m to.m below ground level across the site.. REQUIREMENTS AND GUIDELINES The Department of Housing and Building has provided the following guidelines: Enhanced foundations can be used on sites with potential for liquefaction provided lateral spreading across the property is less than mm. A slope over the building platform of.% ( in ) is acceptable after a liquefiable event. 6. ASSESSMENT OF LIQUEFACTION REQUIREMENTS AND GUIDELINES
6--Jw-Geotech-R-69 Consulting Engineers CPT results have been analysed to assess the potential for soil liquefaction and settlement. Results are attached in Appendix. The assessment of liquefaction has been undertaken under ultimate limit state design (ULS) criteria and serviceability limit state design (SLS) criteria. The ultimate limit state is reached when the applied stresses actually exceed the strength of the structure or structural elements causing it to fail or collapse. The serviceability limit state is the point where a structure can no longer be used for its intended purpose but would still be structurally sound. The tolerances for serviceability depend on the intended use of the structure and can vary significantly. 6.. Ultimate Limit State Design (ULS) 6... Design Parameters Design parameters have been calculated for analysing the CPT results. Calculation of the peak horizontal ground acceleration (PGA) has been calculated in accordance with NZS7.: using the following formula: Ah = Z R C Where: Z =. (base PGA called hazard factor given by NZS 7.:) R = ( in yr return period factor given by NZS 7.:) C =. (Site response factor called spectral shape factor, based on class of soil and given by NZS 7.:) Ah =. x x. =.99 m/s The magnitude earthquake recommended for all common liquefaction assessment procedures in Christchurch is M7.. 6... Results and Analysis The results of the 7 CPT investigations under ULS design earthquake parameters show that there is generally a low risk of liquefaction across the site. Only one test location, CPT 6 near the south western corner of the house, indicated a high risk of liquefaction at a depth of some m. The site is not in close proximity to a river of free excavated bank and is not considered subject to lateral spreading based on observations from aerial photographs. ASSESSMENT OF LIQUEFACTION
6--Jw-Geotech-R-69 Consulting Engineers The CPT investigations were undertaken around the outside of the building due to equipment access limitations. It is assumed that the variability between CPT results in close proximity will equally apply inside the building footprint. Vertical Settlement The CPT locations have been plotted below, and a filled contour plan of vertical settlements across the site has been generated. A larger version of this plan is attached in Appendix. Figure. Filled contour plan showing vertical settlement across the site under ULS design earthquake parameters. Maximum settlement under the design earthquake parameters due to liquefaction was calculated to be approximately 6mm at the location of CPT6 at the southwestern side of the dwelling. Results also show that the western side of the site is more prone to liquefaction with higher liquefaction potential indexes. The rest of the site has vertical settlements ranging from to mm. Although liquefaction is a major cause of earthquake damage, little harm occurs unless liquefaction generates some form of ground surface disruption or ground failure. A study undertaken by K. Ishihara in 9 presented preliminary empirical criteria for assessing the potential for ground surface disruption at liquefaction sites. The criteria are based on relationships between the thickness of liquefiable sediment beneath a site and the corresponding thickness of overlying non-liquefiable soil. A summary of the settlement results, depths to liquefiable layers, thickness of liquefiable layers and liquefaction potential index across the site are tabulated below: ASSESSMENT OF LIQUEFACTION 6

All data points above the line signify occurrence of surface effects of liquefaction. The assessment against data from Ishihara 9 shows that the thickness of the surface layer is generally adequate to prevent sand boils and small fissures coming to the ground surface with the exception at the location of CPT6. It is likely that surface effects of liquefaction will occur along the southern portion of the house. ASSESSMENT OF LIQUEFACTION 7
6--Jw-Geotech-R-69 Consulting Engineers Differential Settlement Differential settlement causes the most damage to structures. It is the differential vertical and horizontal displacements which cause stresses on the structure and induce damage to foundations, flooring, structural connections, cladding and the roof. Differential settlement has been calculated between CPT6 and CPT, giving an angular rotation of % under ULS design parameters which is inside the regulations. This is taken as rotation from one side of the building platform to the other. Maximum differential settlement is between CPT6 and CPT with an angular rotation of.%. However, these CPT s are in close proximity and the stresses resulting from the differential settlement are expected to be spread across the entire structure reducing rotation. 6.. Serviceability Limit State Design (SLS) 6... Design Parameters Design parameters have been calculated for analysing the CPT results.

6--Jw-Geotech-R-69 Consulting Engineers Figure. Filled contour plan showing vertical settlement across the site under SLS design earthquake parameters. Maximum settlement under the SLS design earthquake parameters due to liquefaction was calculated to be approximately mm at the location of CPT along the western side of the dwelling. Settlements of up to mm were calculated at the location of CPT 7, at the south western corner of the dwelling. Calculation of liquefaction induced settlement at the other CPT locations indicates settlement. A summary of the settlement results, depths to liquefiable layers, thickness of liquefiable layers and liquefaction potential index across the site are tabulated below: CPT Settlement (mm) Depth to liquefied layer (m) Thickness of liquefied layer (m) Liquefaction Potential Index (RISK)..

All data points above the line signify occurrence of surface effects of liquefaction. The liquefaction assessment using SLS design earthquake parameters shows that surface effects of liquefaction are not likely to occur during the design earthquake across the site. Differential Settlement Differential settlement has been calculated between CPT6 and CPT, giving an angular rotation of.% under SLS design parameters which is inside the regulations. This is taken as rotation from one side of the building platform to the other. Maximum differential settlement is between CPT6 and CPT with an angular rotation of.9%. However, these CPT s are in close proximity and the stresses resulting from the differential settlement are expected to be spread across the entire structure reducing rotation.

LIQUEFACTION REMEDIATION MEASURES Two approaches are generally used to mitigate liquefaction and its consequences:. Soil Remediation. Structural Modification While these are discussed herein it is generally impracticable with a building in place due to the impracticality of large machines working and the cost of working in confined spaces. 7.. Soil Remediation Soil remediation measures effectively reduce ground deformation and effects of liquefaction by preventing/limiting/slowing-down the development of excess pore water pressure and/or by limiting the development of shear strains and vertical strains in the ground. Soil remediation is usually based on one or a combination of the following measures: Densification (compaction, vibro-flotation, compaction piles, preloading) to increase liquefaction resistance and reduce deformability of the soil through increased strength and stiffness. Solidification (deep mixing, permeation grouting) through cementation of soils. Containment of liquefied soils and limitation of ground deformation by reinforcement and soil mixing walls. Drainage (pre-fabricated drains, stone columns) for increased permeability and faster dissipation of excess pore water pressures. LIQUEFACTION REMEDIATION MEASURES
6--Jw-Geotech-R-69 Consulting Engineers Results of the 7 CPT tests show that there is generally a low risk of liquefaction across the site with the exception of the southern end of the dwelling where a high risk was identified. An option for soil remediation that may be suitable at the site is vibro-replacement stone columns or deep soil mixing. This would need to be undertaken with the building removed and may not be practical in this instance. During the vibro-replacement method a probe cavity is filled with imported materials such as crushed stone, gravel or sometimes concrete. Vibro-replacement can improve the liquefiable soil by densification, increasing the lateral stress, reinforcing the soil mass with the stiffer columns of fill material and providing increased drainage of earthquake induced excess pore water pressures. Deep soil mixing involves the mixing, and sometimes partial replacement, of in-situ soils with cementitious materials or grout. Deep soil mixing uses mixing augers that inject the cementitious material or grout into the surrounding soil through the auger stems as they continue to rotate and mix the injected matter with the existing soils. Testing is required prior to deep soil mixing; using different levels of cementitious material mixed with the existing soil to find the ideal unconfined compressive strength. 7.. Structural Modification Potential effects of liquefaction can be taken into account and accommodated in the design or strengthening of the structure in order to reduce differential settlement. This is commonly achieved by using stiff raft, rigid foundation beams/walls or pile foundations with sufficient lateral capacity to resist both inertial loads due to vibration of the structure and kinematic loads due to ground movement. If the building is to be rebuilt and a stiffened raft option is selected, there is still potential for the whole structure to rotate. CPT results show that differential settlement will likely be above the minimum allowable angular rotation of.%. If no soil remediation measures are undertaken prior to the repair or re-build, then structural modification of the building will be required to reduce differential settlement to below the tolerance of.% angular rotation. If a repair strategy is approached, then the recommended option is to underpin the perimeter concrete foundation with flexible pile foundations. The piles should be extended through the liquefiable layer and pinned into the dense material below. This will require a specific engineered design at the building consent stage of development. LIQUEFACTION REMEDIATION MEASURES
6--Jw-Geotech-R-69 Consulting Engineers. STATIC SETTLEMENT BELOW FOUNDATIONS CPT results have been analysed to assess the level of static vertical settlement beneath foundations of future dwellings at the subdivision. Due to the identification of a fine grained sensitive soil in CPTs 6 and 7, we anticipate further static settlements along the south western portion of the structure. A foundation system consisting of a.m wide x.m deep strip footing (i.e. for a concrete slab floor) has been used for design purposes with a conservative kpa footing pressure. A length to breadth footing dimension ratio of has been used for the calculations. A summary of the static vertical settlement results are summarised below. CPT Static Vertical Settlement (mm) < < < < < 6 < 7 < Table. Summary of static vertical settlement at each CPT location. The results show ongoing static settlement across the site will be negligible. It is likely that the organic soils identified have already undergone settlement and some of the settlement observed in the level survey is a result of this. 9. STATIC BEARING CAPACITY OF FOUNDATIONS The ultimate bearing capacities for a.m wide x.m deep strip footing have been calculated with varying results between CPT test locations at the site. Allowable bearing capacity has been determined using a Factor of Safety of. Bearing capacity calculations are included in Appendix. Results shown in Table below show allowable bearing capacities vary significantly across the site.

Care is required as the density of the upper layers varies and heavy compaction below the foundations is recommended prior to construction. Generally the allowable bearing capacity should be in excess of kpa.. FOUNDATIONS Maximum vertical settlement at the site under SLS and ULS design earthquake parameters was found to be mm and 6mm, respectively. In accordance with the liquefaction deformation limits and house foundation implications (Table below, taken from DBH Guidelines), the vertical settlements are within the limits recommended for a TC site and therefore enhanced foundation solutions will be suitable (DBH Guidelines Section.). Table. DBH Guidelines for the Geotechnical Investigation and Assessment of Subdivisions in the Canterbury Region Liquefaction Deformation Limits and House Foundation Implications. The liquefaction analysis indicates that the building will be subject to ongoing settlement from SLS Serviceability Limit Loads and ULS Ultimate Limit Loads during the ongoing earthquake sequence that is being experienced in the Christchurch area. The CPTs identified a hard founding layer (gravel) at depths of between and 6m. The future foundations and building interaction will need to control horizontal and vertical differential settlement to ensure the induced concentrated stresses do not FOUNDATIONS
6--Jw-Geotech-R-69 Consulting Engineers damage the building. The resulting damage from an earthquake event should be able to be repairable through an earthquake sequence by re-levelling the building. Considering the thickness to the liquefying layer and geotechnical conclusions identifying the damage that has occurred to the building foundations treatment of the ground and/or repairing the foundations are required. This will require. Ground improvement. Reconstructing the building on a raft foundation. Completing these options with the building in place will be economically challenging. If soil remediation measures are undertaken, then a concrete slab floor of stiffened raft or rib raft design may be constructed directly on the ground surface. Options for soil remediation are:. Cement stabilisation with -6% cement re-worked into the existing ground up to m thick with building foundations constructed on this layer. This will act as a bridging layer and prevent liquefaction from reaching the surface. The stabilised pad should be extended at least.m past the building envelope.. Vibro replacement stone columns consisting 6mm diameter columns extended a minimum of -6m below ground level to be pinned into the un-liquefiable subsoil beneath. If no soil remediation is undertaken at the site, the following foundation option is recommended:. Construct an enhanced reinforced foundation wall. This would require underpinning the ring foundation by driving or boring flexible timber piles to below the un-liquefiable soils at a depth of some -6m. A replacement foundation wall could be constructed on top of these piles and tied into the existing foundation. This would require specific engineering design.. Re-level and repack the concrete piles supporting the timber floors and internal walls. It may be that some settlement occurs in future events and provision should be made to re-level the internal footings if this occurs. Alternatively, strengthening of the structure could restrict this settlement.. CONCLUSIONS AND RECOMMENDATIONS Geotechnical investigations indicate that the subsoil properties do not have strength parameters necessary for ongoing support of the existing building without ground improvement and/or repairing the foundation system.

Summary of LPI, vertical settlement and differential settlement for 7 CPT tests taken across the site. Calculations to date using the design earthquake parameters from NZS7. show the following: SLS maximum dynamic settlement is approximately mm with an expected differential settlement across the building platform north-south of mm causing angular rotation of.%. ULS dynamic settlement is 6mm with an expected differential settlement across the building platform north-south of mm causing angular rotation of %. The un-liquefiable surface layer thickness is generally thick enough to prevent surface effects of liquefaction including sand boils and small fissures except along the south western portion of the house where surface effects of liquefaction may occur. It is advised that the building under ULS loading is flexible enough to allow these movements without collapse. The following recommendations are to be incorporated into the building construction:. It is recommended that soil remediation or a new foundation system at the site be constructed.. Soil remediation is recommended to prevent sand boils penetrating the ground surface, reduce differential settlement and maintain the integrity of the building. This is unlikely to be economically practicable with the building in place. a. One option for soil remediation is cement stabilisation of the top m subsoil with -6% cement re-worked into the existing ground. The stabilised pad should be extended at least.m past the building envelope. a. Option two for soil remediation is vibro replacement stone columns consisting of 6mm diameter columns extended a minimum of -6m below ground level to be pinned into the un-liquefiable subsoil beneath. CONCLUSIONS AND RECOMMENDATIONS 6
6--Jw-Geotech-R-69 Consulting Engineers. If soil remediation measures are undertaken then the foundations of the new building may be constructed directly on the re-worked ground. A concrete slab flooring system of rib raft or stiffened raft design is recommended. 6. If no soil remediation is undertaken at the site, the concrete ring foundation will need to be replaced with an enhanced reinforced foundation wall and underpinned with pile foundations to reduce differential settlement. Pile foundations will likely consist of -mm diameter driven timber piles pinned into the un-liquefiable subsoil beneath. The internal piles supporting the floor should be repacked and re-levelled with a provision for furthering re-levelling in the event of further events. 7. The ground is suitable for the construction of services and these should allow for being subjected to earthquake dynamic loads and liquefaction zones.. All re-build works should be carried out under the guidance of a Chartered Professional Engineer with relevant experience..
