Limited Head Space for 7822DT
Very little head room. The vertical work space for this 7822DT was only 13 feet, but it was enough for Hynes & Associates to collect foundation information for structural modifications for the building.
Hynes & Associates, in Salisbury, MD, recently completed another difficult drilling project using a Geoprobe® 7822DT. As the drilling contractor for Columbia, MD-based Geotechnical Laboratories, Inc. (GeoLab), Hynes & Associates was to drill two test borings inside a building that was in the process of being modified, and drill one boring outside of the building. The structural engineer needed GeoLab to provide foundation recommendations on a very quick turnaround time for structural modifications that were in progress for the Cumberland Dye Works in Cumberland, MD.
GeoLab had already attempted test pit excavations. The test pits were unsuccessful due to the rocky conditions.
Mike Hynes, Hynes & Associates’ Drilling Manager, was able to drill the Standard Penetration Test (SPT) borings inside the building with temporary lighting and heavy-duty fans to circulate air inside the building. The head room was only 13 feet.
The field team completed both interior borings and one exterior boring in one day. The borings were drilled to refusal at 16.5- to 20.5-feet.
“Our Geoprobe® 7822DT made a difficult job easy. The versatility of the 7822DT delivered another successful project for Hynes & Associates and for our customer,” Mike said.
