2021 Snapshot:
At The St. Louis Municipal Opera Theatre, the show never really stops—even during construction.
As the country’s oldest and largest outdoor musical theatre prepared for a major transformation, the goal was clear: modernize a 100-year-old venue without missing a beat. But behind the scenes, that meant rebuilding a 120’ wide stage, upgrading lighting and production systems, and threading new infrastructure into a space defined by history, performance, and precision.
As part of the historic “Second Century Capital Campaign” improvement initiative, TWM provided the surveying backbone for the entire work effort—establishing a control network tied to site datum and laying out critical elements like column centerlines, lighting towers, and stage components. But this wasn’t a typical layout. The iconic shell walls surrounding the stage were curved in multiple directions, while the structural steel needed to be installed at entirely different angles.
It was a puzzle in three dimensions and our team helped solve it. Working closely with contractors, our surveying group held coordination meetings and even ran a pilot project to demonstrate how we could accurately locate connection points for steel along the curved walls. Using terrestrial LiDAR, Cyclone software, and aerial work platforms, we mapped the space with precision and helped bring clarity to a complex build—ultimately getting the project back on schedule.
The Muny upgrades went far beyond the stage itself. From a new orchestra pit and automated turntable to backstage renovations, scenery shops, enhanced storage facilities, and even underground soil and irrigation systems designed to protect the site’s iconic oak trees, every element required careful layout and coordination.
When the curtain finally rose on the new stage, the transformation was seamless to the audience—but behind it was a highly technical effort grounded in precision.
And in the words of the contractor’s project team, it was clear that “this couldn’t have been done without TWM.”
