This is one of those rare and fun projects that come our way, the world renowned artist, Beverly Pepper invited us to work with her to build a LandArt commission in our home county of Marin. The photos following show the adventure of developing a massive “cyclopean” style wall to bring her vision alive. This first image shows our master mason, Oskar Kempf, standing next to one of the giant boulders we found in the Sierra foothills, which will become a stone in the art piece. The project was challenging in both the concept of using such large pieces of stone, to the design process that allowed the artist to approve each boulder as we located them and then used photographs to fit into the CAD drawings using photoshop. Transport of the large stone, cutting them and working them into the precise shapes, engineering a 100 ton wall to rest opposing gravity, all challenges that our team had to overcome to make this happen. Beverly was so pleased with the final piece that she featured it on the cover of her newest monograph, Monumenta.

We used cardboard models along with CAD and Photoshop to develop the artist’s design and coordinate with engineering and site work.

Cutting the boulders down so we could work them into the patterns of the walls.
We dry laid the boulder pieces so we could work the joints to fit tight, you can see the scale of these pieces in relation to our masons. We used an ariel lift so that the artist could view them in perspective.
We constructed timber centerings as we erected the stones then placed reinforced concrete behind to capture each course. Complex stone engineering and construction is a QuarryHouse hallmark.
Cutting and detailing the final courses.
Nearing completion and ready to remove the bracings.
The folks at Redhorse Constructors did a beautiful precision grading to offset the finished work.
