We provide seismic engineering services for:

Commercial buildings
Schools and education facilities
Community buildings
Existing residential buildings
Industrial facilities
Heritage and character buildings

Our Seismic Engineering Approach

Assessment

We undertake Initial and Detailed Seismic Assessments to understand building performance and identify potential strengthening requirements.

Design

Practical strengthening solutions are developed to suit the building, budget and future use requirements.3.

Delivery

Essen Engineering supports projects through documentation, consent processes and construction monitoring to ensure strengthening works achieve the required outcomes.

Tinakori Road

Seismic Assessment, Repair & Strengthening

Essen Engineering provided seismic assessment, strengthening design, repair detailing and construction support for an existing multi-unit building at 241 Tinakori Road, Thorndon.

The project involved assessing the building's seismic performance, developing strengthening solutions and undertaking structural repair works designed to improve resilience while supporting the continued use and long-term value of the building.

Project Highlights

Existing multi-unit building
Detailed seismic assessment
Structural strengthening design
Building repair works
Construction monitoring
Producer Statement certification
Improved seismic resilience
Continued building occupation during upgrades

The Challenge

The project required strengthening and repair solutions that could improve seismic performance while working within the constraints of an existing occupied building

Key considerations included

:Existing structural limitations
Building damage remediation
Seismic performance improvements
Construction-stage coordination
Preserving the ongoing use of the building
Delivering practical and cost-effective strengthening solutions

The Engineering Solution

Essen Engineering developed a strengthening strategy incorporating targeted wall strengthening, repair works and structural detailing designed to improve overall building performance under seismic loading.

The design combined assessment findings with practical strengthening measures that could be constructed efficiently while maintaining the character and functionality of the existing building. Supporting documentation included strengthening drawings, repair details and construction monitoring throughout the delivery phase.
