Ivan Rupnik

                 Founding partner,  MOD X 



Modularization precedes digitalisation


In 2017, the McKinsey Global Institute demonstrated that construction productivity annually since 1968, while nearly every other sector of the economy including manufacturing, retail, and agriculture has grown. Why has construction been excluded from any appreciable productivity gains over such a long period of time while vast economic opportunity costs continue to accrue? Utilizing case studies from the US, Europe and Japan, Professor Rupnik will demonstrate how concepts like modularization and product platforms can be successfully applied to construction to increase the affordability, quality sustainability and equity in the built environment, particularly in housing delivery.
Born of academia, MOD X ™ is a knowledge management enterprise, bringing applied research expertise, connections and experience to both new and established players in the industrialized construction sector.  MOD X offers advisory services, exchange tours, and educational sessions, live and virtual, regarding industrialized, offsite and volumetric modular using our broad network of affiliates and collaborators in academia and industry.



Jokūbas Vaišvila

Co-founder, Chief Technology Officer, Strato Group


We are the robots


Jokūbas is a typical millennial – first generation that grew up in the age of the internet. Jokūbas started his engineering career at 15 as a structural design CAD draftsman in his brother’s company. After in-depth preparation for architectural studies, he decided to dive into building energetics and renewable engineering studies and currently holds a Thermal Engineering Master’s degree. Jokūbas carrier is closely related to buildings and computers – in 2008 started working in an international wooden house builder company and in 2012 started his BIM journey and worked hand-in-hand with such companies as MOE, AECOM, NIRAS, Mott MacDonald, etc. optimizing their BIM design phase processes. Jokūbas worked at Autodesk Authorized Developer company and was a product owner of the MEP product branch.

While the BIM process has massive potential to reconstruct the building industry, it has failed to deliver on its promise of improving industries’ productivity, error rate, environmental impact. The construction industry is ineffective and fragmented because of the lack of automation, digitalization, and innovation. Currently, Jokūbas holds a CTO position in a Lithuanian-based #ConTech Startup called STRATO GROUP – the sky has no limits, innovations have no boundaries! Jokūbas is pioneering innovative technologies for the design-built process, such as AI-driven building design software, off-site manufacturing technologies for modular and panel buildings, and large-scale construction 3D printing technologies.

Jokūbas’ millennial character traits like a mix of tech-savviness, combined with a need for personal interaction, help drive changes across multiple generations while infusing the industry with a fresh new perspective.

Andrea Niggl Contech

Dr.-Ing. Andreas Niggl

 Development manager, SOFiSTiK AG


Integrated Structural Analysis – the future of working

The AEC sector in general and structural analysis in particular is still lagging in terms of digitization. Models are set up repeatedly, data is transmitted in formats with reduced information content like drawings or even on paper. SOFiSTiK as one of the leading software providers for structural analysis and detailing committed itself to overcome those issues by providing fully digital, BIM integrated workflows, enabling users to speed up their processes and to create designs of better quality.

The presentation will give an insight into what is already technically possible today and how we at SOFiSTiK see the future of structural engineering integrating into BIM workflows. It will cover aspects like parametrization, automatic generation of analysis models from architectural BIM Models or new data formats emerging in the community for the exchange of structural analysis data and results.

However, it will also rise questions. If the structural engineer will work more closely connected with other participants in a BIM process, not only the technical preconditions need to change but also the mindset and the workflows of the structural engineers itself. It will be discussed, for example, how important it is to have a common model of high quality and who should be responsible for it and how all this might affect the job description of the future structural engineers.
