130 year old house
Hi guys, general contractor here with a bit of a debate between me and my engineer. Architect plans call for a bathtub relocation that would involve drilling an 1.75 inch hole through three of these 2x8 joists. I suggested adding strength to the existing beams by sistering new 2x8’s resting on a 2x4 blocking (this would also allow me to level everything out as well). My engineer suggested only sistering with 2x6’s and nothing else. Any insight or other suggestions I can bring to him?
