Construction Services

A geotechnical evaluation cannot be considered complete until observations are performed during the construction phase of a project.

EEI provides construction materials testing and observation services for a variety of projects ranging from small, single-story buildings to multi-story complex structures, dams, levees and transportation-related elements including roadways and airports. All of our engineering technicians observing the construction maintain certifications by the American Concrete Institute (ACI), certifications for the safety and use of nuclear density gauges as well as INDOT certifications for Construction Earthworks and Concrete Paving. In addition, we have technicians that are certified by INDOT as a QA/QC Technician for Hot Mix Asphalt, Site Manager,  use of a dynamic cone penetrometer (DCP) for lime-modified soils, light-weight deflectometer (LWD) and multiple other test methods for concrete and soil.

Engineering technicians are typically assigned to provide services throughout a project. This allows familiarity with project plans and specifications and continuity for reporting daily observations and test results. In addition, the technicians are supported by geotechnical engineers and other specialists with numerous years of experience with construction materials related issues. This involvement can provide valuable insight into the construction process in order to expedite the schedule and/or reduce the risk of future distress. As with the other services we provide, we are selective about the number and types of projects that we accept so that we can maintain a level of service that our clients have come to expect. Our approach includes much more than a “test and report” service. EEI is devoted to providing a service that supports the entire team with the goals of constructing a quality project within the schedule and under budget.
