Hammer & Steel

As an example, a customer of Hammer and Steel's needed to install 8,800 piles (4" galvanized pipe x ¼" wall thickness) to hold 27,000 photovoltaic solar panels. The pipes were vibrated into fairly dense ground, using a new TM 10/12.5 Mobilram with an MRZV vibratory attachment. Because the solar panels pivot and can act like a sail, it was critical that the foundation piles had the uplift capacity and side load capacity to withstand significant winds. For this job, the piles plumbness, accuracy of location, alignment, and pile top (butt) elevation were all extremely critical.
