Petone Engineering was contracted to carry out the seismic strengthening of Qual IT House at 22 The Terrace in Central Wellington.
- Steel weight – 122 tonnes
- Estimated Hours – 14,600
22 The Terrace is a ten storey building constructed in the late 80’s.
The project involves the seismic retrofit of the building to 100% NBS.
We were contacted by Catalyst early in the project to comment and consult on the design.
We offered some design modifications and alternative options at a round table meeting with Catalyst and Beca.
After completing a cost and feasibility assessment it was decided some of the options we presented added substantial value in terms of reduced costs and quicker installation, and were adopted into a new design for the building.
This project shows the benefits of early sub-contractor involvement in the design phase of a project.
The building itself consists of a basement, 10 floors and a roof services facility. It is surrounded by adjacent office blocks on 3 sides.
The strengthening is on every floor and mostly internal with a small amount of exterior work on the eastern wall. Positioning the steel components on the required floors was a challenge, and the steel was designed to accommodate the tight access.
