NZ National Seismic Hazard Model Update

RBG has been operating in New Zealand for over 6 years. Our leadership team is made up primarily of NZ-trained engineers who have returned to NZ after working abroad in one of our many RBG offices across the globe. We are engineers who ‘grew up’ on seismic engineering, refining and expanding our technical skills while working on some of the world’s most complex engineering projects.

The Oxlade – Project Milestone

December saw the final pour of the Hydrostatic Basement floor at The Oxlade (80 Oxlade Drive, New Farm). This is a significant milestone for the team on-site and marks the end of a challenging excavation process through very difficult soil conditions. The Basement 3 Hydrostatic slab is typically 800mm thick with 1200mm thickenings and a section of a 2000 deep raft which enables the structures to span over a heritage sewer.

The Oxlade is a high-end luxury apartment building, architecturally designed by Bureau Proberts for developer Seymour Group. The site sits on top of a heritage sewer that can’t be disturbed or surcharged, so as a result the hydrostatic slab not only retains the hydrostatic pressure but transfers two cores, a shear wall, and 8 columns across a two-meter deep raft. The deep raft spans to a series of sleeved piles which run to a depth of circa 30m below raft level to transfer the loads to the underside of the heritage sewer. Congratulations to the team on this milestone! It will be a great project to follow.

Engineering the Heart of Expo2020

RBG, in collaboration with Cimolai Rimond Middle East, developed the Construction Methodology and Erection Sequence (CMES) for the Al Wasl Trellis, simulating the construction of the Trellis with a Digital Twin whilst also implementing predictive and live health monitoring of the strand jacking operation for the 900t ‘crown’ lifted in September 2019. RBG was awarded Consultant of the Year for its positive contribution to the centrepiece of Expo 2020.
