Local Authority Earthquake Assessments

Hadleys have undertaken numerous seismic assessments for Local Authorities in the lower South Island including Initial Seismic Assessments (ISAs) and Detailed Seismic Assessments (DSAs).

Council Offices and Library ISA

Hadleys completed ISA assessments for the Queenstown Lakes District Council on 5 buildings in Wanaka and Queenstown to identify the seismic risks associated with the offices following learnings from the Christchurch earthquake events. Hadleys also gave advice to QLDC on the relevance of utilising certain buildings as disaster recovery centres and the impact of that on seismic risk assessments.

Lakes District and Southland Hospitals Seismic Assessments and Upgrades

Hadleys were engaged by the Southern District Health Board over a period of three years to complete both initial and detailed seismic assessments of a number of SDBH building assets, including Lakes District Hospital and eleven separate buildings at the Southland Hospital site in Invercargill. Some buildings identified as potentially earthquake-prone during an initial seismic assessment have subsequently been proven to be a low risk due to our detailed analysis and ability to make beneficial use of the ductility of the structure and its individual members. Structural improvement and strengthening works have been completed for the Boiler House, Chimney and Coal Store.

Southland District Council Seismic Assessments

Hadleys completed Initial Seismic Assessments on 10 Council buildings around Southland for the Southland District Council. Following this Detailed Seismic Assessments were carried out on 5 buildings which resulted in strengthening design works being completed for one building.
