[TowerTalk] Fwd: Foundation and ReBar Work

[Hans Hammarquist]

 Just to add to the discussion:

I had (some thing you can make in concrete) a 6 x 6 foot granite plate, 8 inch think. I drilled holes in it and attached six angle iron to it. I had a guy with a back hoe to bury it 5 feet below ground and filled back the dirt over it Left was the angle irons surrounded by cement. The irons were, two by two attached to the tower legs with the same bolts that were used further up the tower. I believe the advantage of this design is that it require lot less with cement/concrete and you don't have to look around where to put the 'left-overs'. This holds a 85 foor alu tower. (To tower weigh ~#300) Just an other penny.

In 2012, I installed a new-to-me US Tower TX-472. I had a contractor dig the hole using a combination of manual labor + backhoe. The backhoe operator didn't hear/understand the word "STOP!", and the hole became extra wide & deep. As it turned out, extra deep was good because it allowed me to backfill with 1-1/2" round rock (that worked against the high water table). I sank a sump pump into the rock and kept the hole pumped out. I'm into that work for $1000.Rebar cost me $200 from a ham friend who is an "artiste" with the stuff. Some sticks of wood allowed us to lower it into the hole.Concrete cost me $1500 for 5000 psi mix. That included rental of a horizontal line pump. That was coordinated through a carpenter/contractor/ham friend. "Rebarman" brought and used his vibrator.There were many other costs involved but, IMO, none were suspiciously high. All things considered, I saved a lot of dough. vy 73,Bryan WA7PRCPhotos + text: http://www.tinyurl.com/wa7prc-tower      Date: Fri, 4 Mar 2016 16:43:37 +0000 (UTC)From: Russ K5ZZRTo: Tower TalkSubject: [TowerTalk] Foundation and ReBar WorkI installed my new 72' US Tower last year and did the work myself including picking it up in Kansas. The 5'x5'x8' hole was dug for $450 which included spreading the dirt at various places on my 5 acres. I was surprised at how accurate it was also, those guys are good. The rebar I would guess was about $150. The cement cost about $750 so the total must have been near $1,200. No other cost were incurred because I was not in a city. I finished the cement myself with the help of the cement truck driver.Russ K5ZZR   ______________________________________________________________________________________________TowerTalk mailing listTowerTalk at contesting.comhttp://lists.contesting.com/mailman/listinfo/towertalk
