TTW Advance

We have always prided ourselves on finding efficient solutions to demanding problems. TTW Advance is at the forefront in the use of computer based analytical techniques to define, refine and assess the behaviour of the structures we design.
Dean Genner, Technical Director - TTW

The built environment sector is undergoing a significant digital transformation; one that is making us rethink the way we work. At the same time new materials, fabrication techniques and building technologies are pushing architects, engineers and contractors to explore their design boundaries.


TTW is committed to developing and investing in the most advanced and innovative methodologies. We give our clients improved project efficiencies, cost reduction and risk-mitigation, plus wider design freedom to meet their vision. TTW Advance is the embodiment of such commitment. We are a multi-disciplinary team that tackles challenging projects and works closely with clients, architects and contractors in making their most ambitious designs a reality.


Our TTW Advance group combines advanced simulation and computational design methodology with our background in buildability, creating design options that consider all the elements and details simultaneously.


Advanced Modelling and Simulation

We are an experienced team of engineers and analysts in the fields of Finite Element Analysis (FEA), building frame analysis, vibration and dynamics, and advanced materials modelling.

Our expertise in advanced simulation leads to higher design efficiency and accuracy, and enables us to provide elegant and sound structural solutions.

Our capabilities include:

  • Advanced building analysis
  • Advanced nonlinear material analysis
  • Thermal analysis
  • Soil-structure interactions
  • Stability and buckling analysis
  • Fatigue analysis and design
  • Vibration and dynamics analysis and testing
  • Concrete behaviour and research

Nonlinear FE simulation assisted in verifying the load paths, stress concentrations, strength and drift capacity of the core wall, as well as predicted crack spacings and widths in the concrete. This kind of analysis is able to predict the performance of a structure and assist designers in proportioning concrete member sizes and detailing of reinforcement.

Parametric engineering                                               

Automating our engineering workflows allows our professionals to explore more solutions and provide a greater level of structural input to the design from concept stage through to completion to realise design intent and facilitate fabrication. This streamlined process allows for geometry adjustment right up to fabrication, with automatic analysis and design updates.



We provide solutions to complex geometry problems that improve buildability and reduce costs while sustaining architectural intent. We rationalise complex geometry to standardise panelisation, node connections and secondary framing, while optimising forms and envelopes to enhance structural performance, shading and comfort.


Understanding data and its intricacies is vital in contemporary engineering. We develop workflows of data from CAD to analysis to documentation, adding accuracy to the process of exchanging information and saving time.


As well as the competent application of commercial software packages to tackle various engineering challenges, our engineers have developed tools that extend the capability of traditional modelling by further leveraging algorithms in the generation of geometry, analysis and design.

R&D and Education

We are committed to ongoing research and development – continuously seeking to improve the level of service we offer to architects and clients. We continue to invest in class leading processes and software and supplement this with in-house software development to enhance our workflows. Efficient workflows allow many thousand design options to be tested quickly and efficiently. By exploring the design landscape and producing intuitive visualisations, our clients can make informed decisions based on detailed analysis and sound engineering principles.
