00This project involved the design and construction
sequencing of a 50-foot high by 75-foot wide wine cave. The cave was constructed
as a dome in lahar that consisted of fresh andesite boulders in a matrix
of highly weathered rhyolite. Cover over the dome is sloping and relatively
shallow, with an average cover of approximately 45 feet. Jacobs Associates'
design included construction sequencing and ground support details using
construction aspects of the New Austrian Tunneling Method (NATM). Ground
support for the dome consisted of 16-foot long, 1-inch diameter steel
threadbar rock dowels and a shotcrete lining reinforced with welded wire
fabric.
