[TowerTalk] Concrete cost comparisons

[Tom Anderson]

Patrick:

You might also check if you have a "U-cart" or similar named operation in your area.  They sell you the already mixed concrete (I used them on a 40 ft Rohn 25 base back in the 1980s).  You just pay for the already mixed concrete.  It somes in a trailer of varying sizes and you pull it to your site and back the trailer up and dump it in the hole.  All we were required to do was wash out the cart before returning it. I just took it to a quarter car wash and invested $1 or so to wash the cart out.

In the mid 1990s I hired a toweer contractor to put the base of a crank up Tri-ex 51 ft tower because where we moved is permeated with underground springs and the first hole 4x4x6 we had dug filled up with water overnight.  We filled that in and the contractor dug and poured the concrete in 1 day.
