The payoff of early subcontractor engagement.

The objective.

Constructed in the late 1980’s, 22 The Terrace is a ten storey building that now presented an earthquake risk due to a low NBS rating. The ultimate objective of this project was to complete a seismic retrofit of the building to bring in back to a 100% NBS rating.

Our solution.

Having being contacted early in the project by Catalyst to comment and consult on the design, we offered some design modifications and alternative options at a collaborative meeting involving both 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 subcontractor 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.

The outcome.

We successfully completed this project in conjunction with our partners and achieved the objective of attaining a new NBS rating of 100%.

Following completion, 22 The Terrace has gone on to receive several industry awards, recognising both its sustainable transformation and the quality of the seismic strengthening work undertaken. The project now stands as one of Wellington’s leading examples of how existing buildings can be upgraded to achieve 100% NBS and a 5 Green Star rating.
