FEATURED PROJECT

NYS Clean Hand Sanitizer Bottling System
When the pandemic started back in March 2020, New York State designated an emergency job to construct a fully functional and operating hand sanitizer bottling system at Shawangunk Correctional Facility.
S&O was awarded this job as a prime contractor, and thanks to a collaborative effort with OGS Region 3, DOCCS, Environmental & Fueling Systems, Hudson Valley Electrical C&M, Arold Construction and others, we spearheaded the operation to successfully complete the system within five days.
