Virtual Design & Construction
The real test of a new technology is whether it truly improves outcomes for our clients. Lewis uses Virtual Design and Construction / Building Information Modeling (VDC/BIM) in ways that meet each project’s specific needs, to reduce cost, streamline the design process, optimize the schedule and eliminate unknowns in advance. The same is true whether we use “full immersion” VDC/BIM, or more targeted applications.
At the new Amazon headquarters, Lewis coordinated 10,000 embeds with a virtual model, which significantly reduced pour cycles, enabling us to complete the buildings three weeks early. Similarly, in planning for our Via6 apartment project, currently in preconstruction, VDC has helped us carve a day from each pour cycle, saving cost and reducing the overall schedule by one month.
In preconstruction for a new science complex at University of Oregon, Lewis discovered that the foundation wall was designed too close to an existing utility tunnel, rendering traditional gang forming of the wall impossible. Using BIM, our team modeled the wall assembly and existing tunnel to demonstrate the spatial constraints and propose a new solution “ using a one-sided form, leveraging the utility tunnel to shape the exterior of the wall. This approach facilitated an efficient construction method while adding approximately 1000 square feet to the building footprint, at no additional cost.
Lewis can create virtual mock-ups, for curtain wall sections for example, in a couple of days rather than several weeks. Virtual mock-ups facilitate an iterative process with immediate corrections, keeping building materials off the critical path and helping architects achieve their vision. Once complete the mock-up functions as a road map for field crews to build efficiently, with no rework.
