Wine Cellar in Lafayette

Wine Cellar in LafayetteThis Y-shaped cave with 1,300 square feet of conditioned space, was tunneled into the Briones sandstone bedrock using a road-header. Concretions in the sandstone challenged the mining contractor. Our work included construction observation, testing for the site grading and the portal construction. The 20-foot cut in soil and rock was excavated top-down in 5-foot lifts, and supported by soil nails and reinforced shotcrete.
