Update:
I just got back from Thailand where I stayed in Pattaya at The Base for 10 days from late February through early March. Construction has begun in earnest, starting at 8:00am Monday-Friday and running until dusk. They are now driving the foundation support pillars. I stayed in Tower B, which is the one just north of Tower A, in a lower room facing the construction. Actually, the noise was not so great, although I would hear it waking up in the early morning hours. In contrast, my LT companions slept soundly through the distant din...how do they do that? I think a higher room in Tower B, especially one facing north (away from the construction) would be OK. Not so sure about anywhere in Tower A. The LK Residence is situated to take the brunt of the noise so would not be such a great choice now. The Apex was mentioned earlier. I think it would be OK if it is your go-to place to stay, but it depends on how sensitive you are to any noise at all.
