Hello; I am hoping to find an answer among experts.... because I am not an expert. Please be patient with me. We are having a new home built. Poured concrete basement, with one main steel I-beam spanning the centre. (Again, I am not in the business, so please excuse me if my terminology is incorrect). Like most new home buyers, we do drivebys of the house to take progress pictures (after hours of course). And we have noticed... 1) When they poured our foundation, two "buttresses" were included at opposite sides of the basement, obviously to support the I-beam. The buttresses had a U-shaped groove? channel? (all of this is concrete) formed on the top. We are assuming that the I-beam would "fit into" these spots and rest upon the buttress? 2) Two days ago, those top grooves appeared to have been damaged in some way. The sides of the "U" appear to have been smashed off on one side, and is severely cracked on the other one. (we have had some savage wind storms recently, so I can only imagine that while attempting to lower the beam, something might have happened). The main portion of the buttress underneath appears to be fine. My question (and I'm not getting an answer from the builder) is this: is this damage likely to cause a significant delay to the construction of the house? Things seemed to be moving along pretty steadily before this, and now for the last week, it appears that there has been no progress. Everything has come to a halt on our house while neighbouring houses have been framed and now have roof trusses up. Again, my apologies if my question is unclear, I don't necessarily know the right words, and I can't just draw a picture to show you what I mean.
