The Construction Services Group at SCI Engineering supplements services offered by our other service groups by observing construction procedures to determine if project specifications have been met. SCI is the largest local provider of construction materials testing services in the St. Louis area and is one of the most diversified in the region. Currently, over 70 engineering technicians and nine professional staff make up the group.

The American Association of State Highway and Transportation Officials (AASHTO) has accredited our laboratory. We participate in sample proficiency programs conducted by the Concrete and Cement Reference Laboratory (CCRL) and the AASHTO Materials Reference Laboratory (AMRL). Representatives of both CCRL and AMRL have inspected us on-site. The Department of the Army has inspected us and granted a validation to perform material tests for the U.S. Army Corps of Engineers.
