3D is what we do.

Accurate virtual construction. 2D to 3D conversions from CAD, electronic data, or even from a sketch – the way it used to be.


Dynamic 3D Civil design & modelling for infrastructure, mining, land development, construction.


Information Modelling for design communication, project collaboration, costs & quantities, management.


Databases, data management, AGS4, geotechnical CAD and BIM.


Engineering data analysis, systems and workflows; CAD/data interaction, extraction. Data virtualisation (‘analog to digital’).


Spatial data analysis, large datasets, GIS to CAD data conversion.

I’m still the person to talk to about 3D Modelling, geotechnical data workflows, and BIM…


…I’m just no longer operating as Enzdata. I’m working with McMillen Jacobs Associates, in Auckland.

How can I help?   Kent  +64 21 45 2112

Kent Langdon was director of Enzdata – and is now Design Technology Associate at McMillen Jacobs Associates

Kent has been in Civil & Geotechnical Engineering since 1993. Seeing-out the 90’s with T+T in New Zealand as a technical hub in their geotechnical wheel, a good part of the first decade of the 21st Century was spent based in London with Mott MacDonald, working with geotechnical data management and 3D modelling in Transportation and Infrastructure. The remainder of the decade he spent in New Zealand Civil and Structural Engineering CAD design roles.

Following opportunities in major transportation projects in Hong Kong, Kent went consulting as Enzdata in August 2010.

Enzdata assisted with 3D Design, CAD Modelling and BIM for infrastructure, transportation and civil development projects in New Zealand, Australia, and Hong Kong until early 2018. He also spent a few years as a technical software and data specialist with Keynetix, having used their geotechnical database system (and Civil 3D BIM tools) since 2001.

Kent is currently working with McMillen Jacobs Associates expanding Civil 3D, Revit, and Cloud collaboration workflows for infrastructure projects across New Zealand and Australia. For more detail on Kent’s work history, refer to his Linked In profile.

Kent is married to Sara and they have three three children. Kent’s other passions include music, theology, the ever expanding MCU, and good New Zealand red wine.

We’ve been pushing data in, out, and through CAD environments for decades.

Our highly-tuned 3D CAD, GIS and BIM modelling skills will help you design, analyse, visualise and manage your project.

Geotechnical Databases

We use Keynetix HoleBASE SI Professional information system to store, interrogate and analyse our geotechnical data. Talk to us about optimising your geotechnical data workflows.


We are highly experienced with the AGS data transfer standard, having worked with it since 2001. AGS4 enables the electronic transfer and storage of geotechnical data regardless of software system.

Civil & BIM

Geotechnical data – boreholes, down-hole test data, sample and lab data – directly inside the CAD or BIM environment.
