DETAILED SEISMIC ASSESSMENTS AND STRENGTHENING

commercial/retail

Detailed Seismic Assessments for multiple medium to large scale developments, requiring the seismic performance of the buildings to be assessed against the current building standards. To assess the seismic performance of the buildings advanced computer analysis techniques were used to quantify the buildings response during an earthquake. This resulted in an accurate determination of the structures seismic capacity. Seismic strengthening was also designed for all the following projects.

Millennium Centre, Auckland
7 no. mainly office buildings (typically 4 storeys) in total over two level basement carparks, part of which are combined over several buildings. The structures generally comprise reinforced concrete frames and precast concrete shear walls, with the 5 storey carpark a steel k-framed structure. Seismic strengthening was implemented to local areas.

85-101 Alexandra Street, Hamilton
4 separate structures including 4 storey carpark podium and two 10-14 storey Office towers, constructed in the 1980’s. Hollowcore slab strengthening works to achieve 100% NBS performance.

165 The Strand, Auckland
2 storey reinforced concrete moment resisting frame with a 2 storey newer steel structure above. Structural strengthening works to allow for 67% NBS performance of the building.

87-89 Albert Street, Auckland
13 storey reinforced concrete moment resisting frame constructed in the 1980’s. Stair remedial works to accommodate building drifts.

1135 Arawa Street, Rotorua
10 storey reinforced concrete shear wall building constructed in the 1980’s. Strengthening of shear walls through the use of fibre reinforced polymer and stair remedial works to accommodate building drifts.
