Emergency Foundations

In response to a tower structural failure in Osceola County, Florida, P&J was contracted to construct a new H tower. The project timeline was a significant challenge for P&J’s team. P&J had to work with a private landowner to build heavy equipment access. Materials procurement, geotechnical investigation, and design had to be fast-tracked to complete, review, and approve a foundation design in four (4) days following the initial call from the owner. P&J improved or built 1.25 miles of access roads, installed SWPPP controls, and mobilized an entire drill crew and equipment compliment in three (3) days. Foundations were drilled and poured by the end of the sixth (6th) day. Forms were removed, demobilization completed, and foundation design concrete strength was achieved in 10 days following the initial call to P&J.

Goat Rock Foundations

P&J was contracted directly by the owner for drilling two shafts 10.5’ in diameter and 26’ foundation depth monopoles in solid granite rock. The project was completed during scheduled outages. Coordination with the owner and access contractor was accomplished with good scheduling and communication.

Farmwell Substation Foundations

P&J was subcontracted to install 250 drilled shafts and formed foundations for a new substation in Ashburn, VA area. The prime’s schedule required P&J to mobilize quickly and efficiently to meet their deadline.
