[TowerTalk] Height of tower foundation with respect to grade

[Dick Dievendorff]

I'd suggest that the concrete base be finished in such a way that water runs
off the base and away from the bolts holding up the tower.  Either a high
center or a slope.

I'm not sufficiently trained to know if the 6" manufacturer's recommendation
is necessary.  It would be a pity to have the city/county final inspection
fail because the base isn't as high as the spec drawing.  Maybe it's no big
deal. But it might be expensive if it is.

Subject: [TowerTalk] Height of tower foundation with respect to grade

I'm preparing to dig a 5'x5'x8' hole for a US Tower HDX-572.  Because of the

proximity to a sidewalk, I would prefer that the top of the foundation be at

the same height as the sidewalk, rather than 6" above grade.  I assume that 
tower foundations are normally above grade to minimize that chance for 
standing water at the base of the tower.  Is this assumption correct? 
Assuming that standing water isn't a problem and that I keep the area around

the base of the tower free of debris, does anyone see a problem with keeping

the foundation level with the grade?
