Silverado Contractors was contracted to perform mass excavation and grading for a hillside project site containing naturally occurring asbestos (NOA). The project required strict environmental controls and dust mitigation measures to ensure safety and regulatory compliance throughout all phases of work.

In addition to excavation, Silverado supported the shoring subcontractor by installing critical shoring systems, including soldier beam and lagging walls as well as soil nail walls. Our team worked collaboratively to stabilize the site and prepare it for ongoing construction, delivering precise earthwork in a challenging geologic and environmental setting.
