I am replacing 2x6 load bering wall with steel beams. We are joining the steel beam to existing foundation wall with either a beam pocket or concrete pilaster as per the drawing.

Which is better and which one is cheaper to do?

My first question is "is the wall rated for the loads it will see with the new beam in a pocket"?

The purpose of the pilaster is to support more of the beam than just the depth of the wall. However I believe you need to ensure your footing extends enough to take the load on the pilaster. Otherwise the extra length of the pilaster is redundant.

I would ask the person who sealed the drawing.

Good luck.

It is not a matter of which option is cheaper, what has been approved by the city on your stamped permitted drawing, when dealing with load and structure.

Don't try and save a buck.

Both systems are good. The cheaper one to do is the beam pocket.

To install a pilaster requires a footing large enough to support it. Depending on the age of your house your footing may be wide enough but not usually the case.

Installing a new footing and the pilaster is usually more time consuming as well as materials than creating a beam pocket.

The beam pocket is way better structually and gives u more room space because u dont have to cover up post with a faulse wall. Then dry wall mud tape and paint!

So beam pocket would be cheaper and better over all. Thats what I would do.

Provided that your foundation wall is in good condition, a beam pocket is cheaper.

This is not typically D.I.Y. type work. You can do a lot of damage if this is not done correctly.

Don't forget to preload your beam before you grout your base plates.

I agree with Mark. The pilaster was spec'd by your engineer or designer and approved by your city because it meets Building Code.
