Tierra provides a broad range of geotechnical, structural and forensic engineering services.   We provide services to a broad clientele base including Federal, State and Local Government entities, private sector corporations, developers, architects, and attorneys.

Tierra owns a fleet of 10 drilling rigs including 4 track mounted rigs that allows us to access difficult locations and navigate tight spaces. Tierra operates its own CMEC certified and FDOT (107007) qualified laboratory facility in Tampa, Florida.  Our laboratory provides specialized testing services associated with geotechnical engineering and construction materials including physical testing of soil, rock, concrete, aggregate, asphalt and composite building materials.   Because of our large drilling fleet, the ability to analyze soil samples in house and our experienced engineering team, Tierra is able to complete ground subsidence assignments within 30 days after the notice to proceed has been approved. 

Once the subsidence study has been completed and the recommendations for remediation of the apparent causes of the subsidence have been formulated, Tierra has the capability to provide remediation monitoring services.  When the specialty contractor(s) have been selected, Tierra provides experienced personnel to monitor the contractor’s onsite activities to verify quantities, provide documentation of the remediation and to ensure the intent of the specifications are being met.  Our remediation monitoring activities may include onsite monitoring of grouting operations, earthwork and /or foundation installations (i.e. underpins).
