Great Grading
Scaling Up: What SWA’s "100% Land Kit Topo" Means for the Future of Grading
When you look at the sheer scale and complexity of the Irvine Great Park, the logistics of grading the site are staggering. That is why SWA Group’s recent achievement on the project is such a massive milestone for the industry: they modeled 100% of the project's grading using Land Kit Topo.

But what does that actually mean in practice?
For decades, the industry standard has been a 2D grind. If a pathway moved or a retaining wall shifted, hours of contour drafting had to be thrown out and redone. By utilizing Land Kit Topo, SWA unlocked the ability to create and edit their grading entirely in 3D. They could lay out the site plan, test spatial relationships, and watch the topography update dynamically in real time. It shifts grading from a tedious documentation task into a fluid, iterative design tool.
The "Switching Cost" Catch-22
So why aren't all firms doing this on their largest projects? It usually comes down to the psychological barrier of the "switching cost."
Firms are frequently caught in a frustrating Catch-22:
The Delay: "We need to save this new computational workflow for a big, meaningful project where it will really make a difference."
The Fear: When that massive project finally arrives, the deadlines and stakes are so high that trying a new workflow suddenly feels too risky.
The result is that teams fall back on legacy methods, and the innovation is delayed again.
SWA’s work on Great Park proves exactly why firms need to break this cycle. Pushing through the initial switching cost on any project yields the highest possible return on investment. SWA demonstrated that computational workflows are not fragile tools meant only for small conceptual studies, they are robust, scalable systems that can handle the most demanding sites in the world.

Sometimes, all it takes is one project to completely redefine how a firm works.
