Main Support Beam question.
I have a 3-story house with a basement that has 2 main support beams consisting of tripled-up wood beams measuring about 2" x 7.5" each. These are about 30' each in length and have 3 fixed steel poles (per beam) spaced pretty evenly.
The beams are cracked in many spots and have sunk into the support pole due to water damage. I am replacing these and have got quotes for both LVL and Steel.
Most recently I received a quote to use 4 LVLs per beam and keep the existing poles/footers. These would be the same dimensions as the existing wood beams with the exception of adding one more (4 instead of 3). This was much cheaper than the steel I-beam route.
Logically, this seems to be fine since LVLs are stronger than traditional lumber and the existing beams have lasted over 100 years. Does anyone see an issue with using the same sized LVLs? Or do I need to be going down the route of steel I-beams with new poles and footers?
