We are trying to set up our TX monthly notice procedures at our company. The Levelset Learning Center resource indicates that for commercial (non-residential) projects for a 1st tier sub contracting with a GC, only a 3 month notice is required and there is no 2 month notice required. I looked at Tex Prop Code 53.056 and it appears from my quick review that both a 2 month and 3 month notice are required of subs at any level. Can you send me the authority for the 1st tier sub on commercial projects needing only a 3 month notice, and not a 2 month notice? Thank you.
