Simulation Helps Virtual Construction Company Deliver on Time

Dassault Systèmes’ Catia, which provides sophisticated simulation support as well as process-management and tracking support, helped CadMakers in the building of the largest all-wood skyscraper.

Simulations are critical to the design and delivery of everything from system-on-chip (SoC) systems to the latest self-driving electric cars. We use simulations to develop application software before a chip is available. Simulations can also be useful in scheduling and showing how devices and projects will fare over time.

CadMakers, a virtual construction company, leveraged Dassault Systèmes’ Catia and Enovia tools to help build the 18-story hybrid mass-timber residence at the University of British Columbia (UBC). The UBC Brock Common building, erected in nine and half weeks, uses 2233 cubic meters of wood building material. Part of this was due to CadMakers’ simulation and scheduling, as seen in this video:

The process was challenging because of the details involved. The components needed to be delivered and assembled in order. There’s a lot of commonality within the design, but this isn’t the cut-and-install process used to build a house from wood. The components are prebuilt and delivered so that construction can proceed quickly.

Even the building of the central concrete core was simulated:

This also requires many components to be employed in the proper sequence.

Part of the challenge of using CadMakers’ approach is to get the buy-in from the trades involved in the actual construction, since they’re not as familiar with the high-tech tools. Of course, seeing the benefits of the process via simulation helped immensely.

Convincing partners to use collaboration tools like Dassault Systèmes’ Enovia was key to keeping the project running smoothly. Enovia is a collaboration and product-lifecycle-management (PLM) tool that’s applicable for everything from building an 18-story hybrid mass-timber building to managing the delivery of a custom SoC.

Architect Kengo Kuma designed an impressive tower (right) that has a very complex façade (left). CadMakers used Catia to generate a 4D construction simulation.


Mass-timber projects are just some of the jobs that CadMakers has been involved with—the company used its data-driven decision-making process to simulate Kengo Kuma’s tower in Vancouver (see figure above). The glass façade is quite complex. CadMakers developed a fully integrated virtual design—including digital fabrication of the design—plus planning for construction services.

So, is mass-timber technology the world’s future building material? For now it represents a tiny part, simply because the companies that supply the materials in the fashion needed to build structures like the UBC Brock Commons building are small, when compared to those involved with existing building infrastructure.

The video below presents the start-to-finish process of building an 18-story hybrid mass-timber building:
