Coffey helped Housing New Zealand reach a seismic resistance rating of more than 33% across their property portfolio to meet national legislation and new building standards.

Situation

Housing New Zealand owns a large portfolio of residential properties.

Following the Canterbury earthquake sequence, Housing New Zealand made the decision to assess its properties across the country to determine whether they were potentially earthquake prone, as a health and safety measure. This initiative identified a number of properties in the Wellington region to be upgraded to meet acceptable national seismic standards prior to being safely re-tenanted.

We were engaged to project manage remediation activities for 46 buildings in the Wellington region. Most of these were more than 50 years old.

To manage costs and on time delivery for such a large number of properties, our client needed a streamlined approach to working with the consultant team.

Structural designs were based on a limited number of generic building types, which meant many exceptions were expected to be found once building fabrics were exposed. Custom solutions would need to be efficiently applied to deliver the project on time and on budget.

Solution

Rather than the more traditional approach where various subcontractors worked independently and reported directly to the client or delegated site contact, we became the primary point of contact for our clients. Having one source of information ensured clearer visibility across the whole project to better inform the decision making process, reduce the likelihood of lost information and relieve project pressures from our client.

As the tender process was complex, we advertised works packages in bundles of 12 properties to ensure their fast turnaround and maximise client value.

Effective communication between our client, consultants and contractors was also established from the outset. This provided a collaborative environment to resolve any structural design issues and deliver practical solutions to minimise costs and delays. 

Result

Strong collaboration and communication throughout the project resulted in pragmatic solutions to meet the required quality standards for the EPB program. 198 homes were remediated to meet acceptable seismic standards, and a large base of affordable housing made available to the region.
