Despite the weather conditions, the contractor is proceeding with work and the IPR was positive.
Work includes a drill rig coring through an anomaly in a drilled shaft that supports the monolith. Once the coring is complete, the contractor cleans out the anomaly and then fills the void with a specialized grout.
