New Zealand has a long history of fatal earthquakes, and as structural engineers, we take our role in providing our services for seismic assessment and retrofit very seriously.

For any Rapid Assessments, Initial Evaluating Procedure (IEP), or  Detailed Seismic Assessments (DSA) that your building needs, DTCE can undertake the report writing, design, retrofit, and monitoring of any structural engineering work involved, including the seismic restraint of services in large commercial buildings. We can also help assess parapets, brick walls, and any other at risk structures that may need inspecting. At DTCE, we are well acquainted with the stringent regulations and building codes that Wellington City Council has enacted to keep buildings safe in the event of a disaster..

If your building needs more work, our most comprehensive report, a DSA, can accurately assess the structural seismic strength of any building compared to the New Building Standard (%NBS).


If the building is found lacking in any areas, the report will outline the measures needed to attain a higher %NBS and the costs involved with the construction.

New Zealand is very susceptible to large earthquakes, and the Greater Wellington region in particular is at risk due to the major fault lines that run through it. With the disaster in Christchurch a reminder of what can go wrong, seismic strengthening is more important then ever to keep your business or residence safe.

Technical Knowledge

With six CPEng Engineers, we have a wide technical knowledge in all aspects of seismic assessment and retrofit. DTCE is always striving to expand our understanding on how structures behave in an earthquake in the hopes of protecting the wider community in a seismic event. In line with this, every year, one of our engineers goes back to the University of Canterbury to complete a paper on some aspect of seismic structural engineering. This ensures DTCE is at the forefront of seismic engineering and can pass this technical knowledge onto any project we carry out. In the past few years, the papers we have completed as part of our ongoing technical improvement include:


This course outlined low damage and resilient design solutions for the seismic design of reinforced concrete structures. The course introduced the latest DDBD (Direct Displacement-Based Design) procedures for designing buildings and also introduced base-isolation, viscous dampers, PRESS-Technology, and other seismic resilient concepts for building design.  This gave our engineers an overview of various solutions and concepts for resilient building design, and on-site applications worldwide in multiple seismic areas, providing valuable insight into constructability aspects, sequences and detailing.


With this knowledge in DTCE can provide multiple low damage and resilient seismic design solutions and assess the best fit for your building with industry-wide applications to meet your expectations.


This course provided an overview of the most common structural weaknesses in pre-1970 reinforced concrete structures, and how to anticipate the behavior and response of existing reinforced concrete buildings. The course gives details on how to employ the latest displacement based assessment techniques on the assessment of seismic behavior of existing buildings. It also discussed the various and strategies  on seismic retrofitting of existing buildings, referencing national and international literature.

Industry Membership

To supplement our internal technical knowledge, DTCE is also a member of multiple organisation and society leaders in the structural and seismic engineering industry. These memberships ensure we are at the forefront of engineering knowledge and gives us the ability to refer to best practices when producing our engineering services for you. Some of these memberships include:
