Education

Elementary schools, high schools, colleges, universities, school districts, and general contractors working with educational institutions entrust INTERRA to provide responsive service, expert consulting advice, and reliable laboratory results to drive their projects forward as quickly as practically possible.  Because school construction projects often take place when students are present, INTERRA provides an even greater level of consideration for construction site safety and the project team’s effort to complete the project on time so that disruptions to the academic community are minimized.

INTERRA has provided consulting services and comprehensive testing services for soils, concrete, aggregate, asphalt, masonry, and structural steel for a large number of schools.  Please find below a representative list of some of these projects.
