[TowerTalk] RE: Erecting tower

[WD0M]

I just poured a base for a self-supporting US Towers TX-455 - the local 
concrete guys said 7 days is sufficient.  I used 4000 psi concrete, and the 
daily highs were in the 50s, lows sometimes into the low teens.  I'd check 
with the local concrete company - they know their product, local weather 
conditions and the specifications.

Click on "Tower Project".  This is a semi-unique installation - I couldn't 
dig a hole for the concrete because it is solid bedrock on nearly all the 
five acres.  The decision was to drill holes in the rock, cement re-bar in 
place, and pour a concrete block around the rebar cage.  It worked out fine.
