Project Cost:


KEG provided field exploration, laboratory testing, analysis, and reporting for the entire Phase I trunk alignment and proposed appurtenances, such as manholes and laterals.  Fifty-seven borings were completed for the project to depths of as much as 30 feet below existing grades.  Rock coring was also performed where impacted.  KEG’s coordination with property owners was a critical part of obtaining access to drilling locations and for successful completion of the exploration within the project schedule.  


Reporting consisted of both a Geotechnical Data Report (GDR) and a Geotechnical Interpretive Report (GIR) for inclusion in contractor bidding specifications. Details of these reports included location and general description of existing fill materials, influence of groundwater and/or rock on design and construction, and further geotechnical construction recommendations.
