As i was visiting the job pictures on this site i ran across one posted that made me cringe. Those pictures of the rather large fireplace being built clearly depicted the violation of every code i know of that dictates the approved method to tie facing material to the C.M.U. backup. The pictures as big as life of the corregated metal ties hanging out of the block is a huge code violation. Corregated metal wall ties are for veneer over wood studs only period. If you are not driving nails through them into WOOD STUDS leave them in the gang box. The codes violated were ACI 530-99 /ASE 5-99/ TMS 402-99. On a job site close by a code official caught work in progress that did the same thing and required the building to be torn down and rebuilt correctly! Where was the architect on this job (it was large enough to warrant supervision) On the drawings (under MANDATORY specifications checklist in the ACI CODE 530 notes to architect/ engineer) Specify the location, spacing,& type of accessories not indicated on the project drawings. It is quite clear there were more then one asleep at the wheel.
