From recent seismic events throughout the country, our team of engineers have gained considerable experience in seismic assessment and performance of buildings. OBD Consultants can help to assess buildings and assist with the design of seismic strengthening works. We can also advise on resilient and damage limiting structures. By offering staged assessments of existing buildings, we ensure our clients are making informed decisions by balancing strengthening options with repair costs, habitability and the future value of the building.
OBD Consultants are experienced in the provision of seismic assessments to both the Initial Seismic Assessment (ISA) and Detailed Seismic Assessment (DSA) levels. We offer conceptual and detailed design of seismic strengthening for earthquake prone and earthquake risk buildings.
We provide initial and detailed seismic assessments for buildings in accordance with NZSEE guidelines and engineering principles. This could be an ISA or a DSA depending on the level of assessment required. Both assessments report seismic capacity as a percentage of a new building standard. When existing structures are not quite enough, we can design retrofit/strengthening solutions to ensure your structure meets New Zealand seismic design guidelines.
