rebar shop drawings
(OP)
Hi,
This an interesting question that perplexed me lately.
Can a 2-story concrete house be built without rebar shop drawings?
the house is on 14" auger cast piles. Fisrt floor concrete slab is 6' above grade.
The second floor and roof are also 7" to 9" concrete slabs.
everything supported on load bearing reinforced CMU exterior walls and interior concrete columns...
Total house area is about 5000 SF, and it is about 35' high.
all concrete construction.
There are transfer beams and slabs due to elaborate architectural features.
The stairs are concrete as well. There are concrete balconies with 6" step down at the door sills.
So, it is clear the house is fairly complicated with a lot of rebars in it.
I looked up the Florida Building Code on this issue but could not find anything.
The project is in south Florida near the cost line in hurricane zone.
I appreciate your thoughts on this.
Regards,

The building official requested that the plans be detailed in such a way that shop drawings would not be necessary and not be required or needed! We have done many similar projects before and never had to deal with this issue in this fashion. Like everyone else we have in our project spec's detailed information instructing the contractor to submit rebar detailing in the form of shop drawing. But in this case the building official still not satisfied with this shop drawing specifications and requirements.
my concern is whether the building official is over reaching and being unrealistic.
our opinion is that the house is too complicated to detail and call out all of the rebars directly on the structural plans.

Shop drawings serve two main purposes: 1) so that the bars can be properly fabricated (not on the bumper of the pickup) and 2) to assure that bars are identified properly and can be placed in the correct part of the building.
Rebar detailers are uniquely qualified to figure out how the bars can be fabricated for economy of material and placement. Very few engineers have the experience or time to properly detail bar. Rebar fabricators generally provide this service as part of the fabrication cost, and dislike cutting and bending on other people's shop drawings. It often results in field problems and inefficient use of stock bar lengths. They may charge a premium to fabricate from outside details, since they may have added waste, and difficult sizes and shapes.
One of our members reported to us that they had a building official requiring that the 100-plus foot bars in a grade beam, shown in drawings as "CONT", be continuous one piece without splices. They finally convinced him it was not really required.

ACI 301, ACI/CRSI 315, and a couple of CRSI committees are working the issue now.
