LDE is the sole company undertaking the geological modelling for the Canterbury Earthquake Recovery Authority. Subcontracting to
Tonkin & Taylor Ltd, LDE is responsible for providing 70km of cross sections of the engineering geology down to some 40m depth
beneath the greater central business district of Christchurch using hundreds of cone penetrometer tests, machine boreholes
and geophysical data. |

LDE is the sole company responsible for the geological modelling of the residential areas affected by liquefaction and
lateral spreading for the Earthquake Commission. LDE has been undertaking this work since the 4th September 2010 earthquake event
and has completed the modelling for all of the areas affected by that event. We are presently developing the engineering geology for
hundreds of kilometres through the additional areas of Christchurch affected by liquefaction and lateral spreading for the Earthquake
Commission using data from thousands of CPTs, boreholes and supplementary geophysical data. |

Mapping the extent
of Lateral Spreading in Christchurch for Earthquake Commission: Read More ...
X
LDE has been exclusively undertaking the mapping of the extent of lateral spreading of land throughout the entire
city of Christchurch and Kaiapoi areas. This has been a significant task due to the extensive areas affected, with
data obtained in it used to assist Tonkin & Taylor Ltd’s recommendations to the government with respect to the
retirement of land in the worst affected areas. |

To date LDE has undertaken geotechnical assessments of 15 earthquake damaged properties for the Christchurch City Council,
including the Canterbury Provincial Chambers and the Shirley Community Centre. Work has included the preliminary assessment
of each property, followed by detailed geotechnical investigations of 9 of the sites with geotechnical engineering recommendations
for the remediation of the land and buildings. |
