Turner used a detailed
digital model to assist in the
construction of a Virginia Mason Medical Center project.
Turner and its team used a lean-design approach called 3P, or Production Preparation Process, on its Level 5 Jones Procedural Center project at Virginia Mason Medical Center.
Using 3P, the Turner team reduced the construction schedule from 10 months to four and saved the client more than $500,000 in productivity.
One of the key elements used by Turner was the concept of “built to design.” To eliminate the as-built process, the project team tied the building-information model to work in the field.
The Turner team worked with an extremely detailed digital model of the project with elements fixed according to X, Y and Z coordinates, including survey field conditions and collected data points. The process of pulling coordinates from the model and re-inputting them allowed the team to build to an XYZ-dictated grid with the expectation of zero variation between the design and the completed, built conditions.
This system provided tremendous value by eliminating variation, increasing quality and allowing for greater prefabrication.
