The piers & cross pipes are 3 inch standard weight (schedule 40) steel pipes. The tops of the piers are connected in the E -W direction by the cross pipes which cantilever over and extend past the end piers. The cross pipes are connected by proprietary IronRidge XR1000 Rails spanning up and down the slope which cantilever over and extend past the top and bottom cross pipes. The solar modules are attached to the rails with IronRidge clamps. There are typically two rails per column of modules. Gravity loads are transferred to the piers and foundations by the rails and cross pipes acting as simple beams. For lateral loads the system is a cantilevered structure. The effect of seismic loads (for all design categories A -F) have been determined to be less than: the effect due to wind loads in all load conditions and combinations. The pier spacing in the N -S direction is 9'-0". The pier spacing in the E -W direction is 10'-10" and is determined by the structural design for the specified design criteria below.

Foundation Requirements The .foundation requirements for a cast -in-place drilled concrete pier system and for each soil class 2, 3, & 4 may be obtained from the tables below. The soil class is noted at the top of the tables. For each soil class Tables 3A -3F and 4A -4F are provided for the 2in and 3in systems respectively. These tables are based on the piers being installed at their maximum allowablelspacing. For spacing values less than maximum and for loads cases with snow > 0 psf, the requirements can be determined by using the online Design Assistant at IronRidge.com. s .
