Throughout the three years on this project, Koury worked and coordinated with Granite-Myers-Rados, Caltrans and Orange County Transportation Authority. Our services included:  geotechnical monitoring, construction inspection and material testing, observation and testing of sub-grade, grading, back-fill and compaction, perform quality control and assurance during concrete batch plant and placement, masonry placement, rebar placement, welding and electrical. Our team conducted tests on soils materials using sand cone and nuclear gauge methods. Other tests performed were rebar bend/tensile, concrete and masonry compression tests, non-destructive ultrasonic and magnetic particle testing.
