CalTrans rented eight DustBoss DB-60s for dust suppression on the Doyle Drive project, with on-site training supplied by the manufacturer.
The Presidio remained open to the public during demolition, so the contract called for a control plan to prevent dust from leaving the project boundaries.
Demolition of the old structure involved approx. 4700 linear feet of roadways, including 150 spans, yet the plan allowed complete road closure for just one weekend.
One full-oscillation DB-60 can cover nearly 125,000 square feet more than (11,600 square meters) with a highly efficient dust-trapping mist.
