Dear Seniors,
One of our running projects has layout problem in which columns are out of 10 inches from center line.We need to adjust it as we have to install steel shed above it.Now there are two options,either we have to dismantle the footings or we have to drill holes and grout new dowels with chemicals.Now the problem is that what should be the depth of drill and if we drill hole then hook (development length) can not be provided.
So please give me suggestions based on your experience.We are using 20 mm dowels and axial load is 146 kip.
Thanks!
