Hello Bryan,



I am  referencing ACI 318 as talking points.



1.    Can  rebar or other metallic materials be used as depth gauges and /
or conduit  support in footings?  Meaning, the rebar or conduit is driven
into the  earth and will also be encased in the footing (burning the  
form)...

a.    ACI Section 6.3 addresses conduits and pipes  embedded in concrete.
It states that really anything but aluminum is  allowed to be embedded into
the concrete matrix so as they do not pose an  adverse risk to the concrete
structure and with the approval of the design  professional.

i.      The
question for your department is  what material is acceptable and does not
create an adverse risk to the  structure?  

ii.      And
what was approved by the design  professional?

2.   Can vertical steel reinforcement be  "wet-set" into footings, or should
the rebar be "tied-in" to the footing  steel?

b.    ACI Section 7.5 Placing  Reinforcement

i.      Shall
be placed accurately and  adequately supported before concrete placement and
"shall be secured  against displacement within tolerances permitted".

1.     Based on ACI it looks like the steel needs to be in the form  prior
to placement.  Naturally I believe a design professional can  allow for the,
let's say, the vertical steel for reinforced masonry to be  placed after
concrete placement but a note most likely would have to be on  the drawing.

ii.
Personally I think all of the steel should be in the  "hole" prior to
concrete placement.  I am regularly called in when  contractors planned on
placing the steel in during concrete placement only  to get busy and forget
about it.  On later inspections they find the  steel that should be in the
concrete on the outside laying on the  ground.  For vertical steel the same
applies with missed placements or  not placed at all because some one took
the 10 for this side and moved it  to another wall segment.  Too many errors
available on the blue collar  side of labor not to require it all to be in
the form at  inspection.

Subject: [Florida Code Talk] Misc.  Policy and Practices Questions



Good Morning  Everyone,



I have a series of questions that are addressed by  the code but are
practiced and enforced widely from jurisdiction to  jurisdiction.  Please
reply with your code references and/or  comments.



1. Can rebar or other metallic materials be used as  depth gauges and / or
conduit support in footings?  Meaning, the rebar  or conduit is driven into
the earth and will also be encased in the footing  (burning the form)...



2. Can vertical steel reinforcement be  "wet-set" into footings, or should
the rebar be "tied-in" to the footing  steel?



3. Can non-treated wood products be in contact with  masonry or concrete
without other forms of decay protection such as felt  paper?  This includes
locations above 6" of  grade.



Thanks in advance for your  opinions...
