Yes, I have studied the Tashjian website and have even spoke with a
representative on the phone.
Unfortinately their online and openly published documentation in my opinion
quite vaugue and incomplete with respect to designing and fabricating your own
base. I would make a guess that a decent amount of marketabilty for them comes
from design services. They will sell a service and paper packaged presentation
with engineering wet stamp of your older second hand tower revised with
reccomendations and recaculated to new standards. They also have a more basic
set of generic instructions that they will ship with new base purchase.
The base with suggested installation instructions with example for areas with
adobe type soil conditions are similiar is included for $395 plus $200 shipping.
This might be very necessary if you require inspection. I am headed right near
there this weekend and considered just paying the $400 and picking it up in
person. However,, they dont carry these pieces in stock and there is a whole
proccess of placing the order and the sales staff places the build ticket with
the production dept. and a notice to notify the proper design staff who orders
the material and sends it to fab who builds it in the order recieved. After its
finished it has to be sent off for galvinizing. In other words it wont be ready
...... ready for several weeks up to couple months and certainly not this same
weekend I am traveling thru there. So now we are looking at $600 to have it
shipped! I am so impatient i would have been compulsed to pay $400 with the
mindset that I am getting some limited factory support for a twenty something
old tower. (the fact that they support old tower that predates their interest
in the TriEx company is really worth a premium) As I
mentioned before I am impatient and I also draw the line at $600 to have to
wait up to ? Months?
Their written review service without any design considerations of your old
tower cost $200
If I was for sure going to be inspected I would buy that....
As far as detailed erection instructions it appears they are going to need to
be reimbursed.
Man! Go look at all the design details and information that US TOWERS makes
avail on their site..... So much for proprietary information. I am acquiring my
rebar and doing concrete work as per US Tower info.... still no fabrication of
actual base stubs. I did acquire 3/8 steel plate tho...... that appears to
match that of the tower legs.
Should I be bumping that up to.1/2 instead?
I agree that 3/4" holes perfectly lined up in 1/2" steal isnt something that
you are going to do with a step bit and a cordless dewalt.
It is my similar thought that these holes would likely be a job for Bridgeport
or similiar milling machine.
As for the steel alloy? Anyone offer up a clue? Also need the size and type of
rebar that is used to weld onto the tabs?
That no weld method sounds like kinda iffy with using angle? I Do notice that
US Tower does similiar with anchor bolts. I just rather see more metal from the
legs going into the concrete below than welded to a top plate. I saw one where
the guy welded gussets . That seemed a bit better. US Tower definately does
alot of rebar work to keep those anchor bolts from pulling out. I Am building
my cage similiar with 2#6 per corner and the 20 #3 ties
