MERIT is reasonably priced, and dramatically reduces cost overruns due to incomplete conceptual modeling.

For example, a recently completed project for the Florida Department of Transportation cost less than $20,000.

Before bringing in MERIT on this project, FDOT contracted 26 Standard Penetration Tests (SPTs) to depths between 50 and 150 feet at an estimated cost of $45,000. The results of these borings did not clearly identify the complete sinkhole feature and therefore did not provide enough detail for accurate risk analysis.

MERIT was employed to provide additional information; the investigation was 550 feet in length and included 28 electrodes implanted to 50 feet. MERIT costs were less than $20,000. MERIT identified the sinkhole throat at 170 feet with corresponding identification of subsurface geometry, including competent limestone, weathered limestone, raveling soils, and upper sand unit.  Also evident was the geometry of the sinkhole depression infilled by the upper sand unit.

Based on the totality of the geotechnical testing and deep geophysical imaging, risk modeling was performed to determine the potential activity of the sinkhole was low. Thus, no additional ground modification would be required to support the proposed roadway.

Had MERIT been employed before the SPT exploration drilling, a more focused program would have significantly reduced drilling costs.

This is just one example of how MERIT imaging can assist in the precise identification of subsurface structures and drive down costs for our clients.

Some factors that we consider in our pricing include:

• Multi-site discounts
• Built in discounts for clients requiring long term monitoring
• Extra features such as 3D modeling, self potential, permanent installation, etc.
• Array size, depth, and complexity
