Our structural engineers are experts at seismic strengthening of existing buildings and post-quake sites, increasing their resistance to seismic activity, ground motion or soil collapse. Using state-of-the-art modern equipment, we're able to map and plan engineering strategies to bring your project or existing building up to code.

From initial assessment to uncovering hazards and damage, we oversee your entire project for you, giving you a detailed scope and making you aware of dangers before we begin. Documenting all repair work, we provide full transparency, ensuring that the final project is completed to your satisfaction.

More about Seismic Strengthening.

The Building Act 2004 sets out New Zealand’s framework for ensuring the safety and performance of buildings, with a particular emphasis on earthquake-prone structures. The Act aims to safeguard public safety by gradually reducing earthquake-related risks, focusing on the most vulnerable buildings. It establishes guidelines and standards for assessing, repairing, and strengthening buildings to withstand seismic activity.

Seismic upgrades, also known as retrofitting, involve reinforcing existing buildings to improve their ability to resist the forces generated by earthquakes. This process is critical in reducing potential damage, protecting occupants, and ensuring the continued use of essential structures after a seismic event. Common techniques include the addition of bracing, strengthening walls and floors, and improving the connections between structural elements. Seismic retrofitting is especially important for older buildings not designed to current seismic standards.

Underpinning is another crucial method for enhancing structural stability. This involves strengthening or deepening the foundation of a building, which may be necessary when the original foundation is found to be inadequate, the soil supporting it has changed due to factors like subsidence, or the building’s usage has changed and now requires more support. Underpinning methods, such as the installation of micro-piles or extending the foundation's depth, ensure that the building rests on a more stable soil layer or distributes its load more effectively. This process helps prevent future settlement or structural failures, particularly in areas prone to seismic activity.
