We are a structural engineering firm carrying out work throughout NZ and internationally.

Since 1979 we’ve been designing buildings throughout New Zealand from our offices in Palmerston North, Wellington, Auckland, and Hawkes Bay. Our philosophy has always been to provide the very best service available to our clients and we work hard to achieve that.

With an enthusiastic and innovative team, we have always strived to be at the leading edge of our profession. 3D draughting technology is utilized on our clients’ projects so that we can construct a structure in our office prior to the actual building work commencing on site. This provides a greater understanding of the buildings for all involved saving time and money for our clients in what is a very competitive industry.

Our work covers a wide range of building sizes and types – we are currently working on small domestic structures, multi-storey commercial buildings and large industrial projects. We are specialists in the design of seismic strengthening and assessment as well as the design and supervision of seismic restraints to services and secondary items. We also specialise in meat and dairy industry buildings as well as leading the way in high rise commercial buildings.

Let us be part of your next project and provide you with the very best service and documentation that is available to you today.

“We found the entire process painless. Silvester Clark corresponded directly with WCC on our behalf. We now have a building that is not on the earthquake prone register. This has added value to our property.”
D. Tingey
“This is good news! Thanks for your help in having our property assessed as being more that 33% NBS. My fellow unit owners and myself appreciate your efforts.”
C. Anderson
“For a total costs of around $20,000 (including professional engineers fees, Council fees and the strengthening work itself) the building has been transformed from an earthquake-prone structure to an 100% compliant building. The Owners are naturally delighted with the result and are highly impressed with the services of Silvester Clark.”
S. Mulholland

Because of yours and Silvester Clark’s urgent and quality assistance, we now have clarity on our next move in pursuing this building.
