O’Neill Service Group (OSG) is a local leader providing quality control (QC) materials special inspections, testing and additional construction related technical support services on the most complex public sector projects in the Puget Sound Region.  Since our inception in 2008, we have provided QC/QA and technical support services on more than $1 billion dollars of public construction projects associated with large-scale transportation, infrastructure, commercial buildings, and industrial and recreational facilities.  These projects were often fast-paced, limited access, highly technical, and required an experienced quality and environmental team with a wide range of inspection and construction related technical services to ensure contract performance.
