1.3 Foundation Preparation
Before beginning the installation process on the ground mount assembly, ensure that the foundation has been
prepared. Foundation specifications are provided by ASC Signal and may be used as a reference by civil
engineering personnel when preparing the foundation for local soil conditions. These specifications are
available before the shipment arrives by contacting the Customer Service Center or your Account Manager.
 Foundation should be dimensioned as detailed in Mount Assembly Instructions (237151C, see Table 1.2)
 Sweep foundation clear of any dirt or debris
 To ensure smooth surface for mount, scrape foundation pads as shown in Figure 1-2
 Studs should extend 3 in. above the ground and are 7/8 in. in diameter
 Apply stick wax to stud threads to ease later connections
