Got the plan drawing back from my engineer. First cost overrun - I was quoted that it would take around 3 hours of work, ended up with a bit over 7. We settled on a flat $550.
Anyway, here are some images of the plans.
This one shows the removal of the current beam and the addition of the new replacement beam.
Here we have the new beam extension. Nothing a little Elmer's glue and spit wouldn't hold togther.
Here are how the joists with be sistered so that I don't need to replace the current ones.
Any finally how the columns will have to be installed. Because the two new columns are so close together, the engineer want one large footing. It will be 4'8" long x 2' wide x 12" deep. Once the column is installed I have to add more gravel and then repour the slab. That's a heck of a lot of concrete!! But also likely where I can save money if I am willing to do it myself.
Looking online it seems I can rent a small concrete mixer for around $20 per day. Assuming I can get it into the basement, that should make the mixing part of the job pretty easy. I'll just need to rent it twice.
The metal work and column and beam installation I will likely farm out. Hopefully I'll find some help because it's a pretty small job.
Anyway, please let me know if you see anything on the plans that could be inproved. This is still all in draft form with the engineer.
