[TowerTalk] Wet setting conduit?

[Craig Sande]

I finally decided not to risk any compromise to the base by introducing a total of 5 conduits.  The pour will proceed tomorrow morning per the original engineering.  When the dust settles, I will take my time installing the conduit runs to the edge of the pier.  I'll probably use a NEMA  box mounted nearby for the lightning arrestor devices and have the conduit enter directly from below.  I'll run a 6" copper strap from the NEMA box to the tower.  I'll be sure to snap plenty of pictures and share my experience when complete.
 
Regards,

Craig,

If it’s a slab foundation and the PVC entries are not near the anchor bolts then it might not be a problem since the foundation is probably designed for its compressive load and its overturning moment. However, if it’s a pier type design, it may be a problem since it could affect interaction with the shaft and anchor bolts. Best practice is to do what you are going to do, check with your engineer. You’ll find addition information about foundation design at http://www.wirelessestimator.com .
