Support beam feedback
I've lived in and have been renovating a 1909 home up here in Canada for the past 13 years. We have got to the stage where a basement reno needs to be done. In the past we haven't spared to much on materials but want to keep the cost of this project down given the times we are in and the fact that we have over capitalized already. Although we may get some return on reno if we ever decide to sell.
Ok to the point. I'm looking for ideas and maybe a pointer to further information on a support beam issue. I will probably bring in an engineer to evaluate also.
We want to open up the space we have but have run into an issue with the 8"x8" solid wood beam not being one piece. As you will see in one of the pictures its lapped and supported by an upright 8x8 set into the poured floor. Now when I reno'ed a room in one corner of the basement 10 years ago I found another 8x8 free swinging as the bottom had rotted out of it. I expect the same has happened to the pictured beam I want to get rid of, but suspect that the wall built sometime in the 60's now taken some of the load of this beam.
I'm looking for a free span from the seen metal telepost to the poured foundation wall (about 12 1/2'). the 2x10 first floor joists are lapped on top of the beam. I'm guessing that a replacement structural beam will be required? Currently there is about a 1 1/2" sag in the 2nd floor but since the main floor was already reno'ed and that I have spent the last 4 years gutting and refinishing the 2nd floor, I have built around and re-hung doors to accommodate.
Ok please excuse this book - I'll provide more detail as required - thanks for your comments.
