Napa Mill Silo Structural Strengthening

Location: Downtown Napa, Ca

Overview: Structural stabilization of two 65’ tall historic grain silos.

Treeline’s role: Our scope of work, as the prime contractor, for the Napa Mill Grain Silos, surrounded by a public market and hotel, was mostly structural and seismic strengthening in nature. We structurally retrofitted the two concrete silos that sit in the middle of the Napa River Inn/Napa Mill Development. We reconstructed the walls and roof of the large portion of the surrounding building structure and constructed the finish product within, as well as historically replicating the original doors and windows.
