We need to begin moving forward on a claim on a payment bond in the state of Texas. We are a sub-contractor hired by the prime contractor. The project was federally funded but the property/land was (I believe) state owned. The state of Texas is named on the bond, so I assume we are using state guidelines/deadlines. Our work was to be paid as a % percentage of completed bid item but after 8 months of various preliminary tasks, meetings, material vendor negotiations, creation of work timelines & consultation, they decided to go with another sub. They sent us an email stating that on 10/19/2018. We invoices them for services rendered & have not been paid/responded to. 1. Does the 10/19 “termination notice” constitute end of work? 2. I have read that a preliminary/monthly notice is required since it’s a Texas state, public project. Is that true? If any notice is required prior to filing the actual bond claim, is it called a preliminary notice or a monthly notice & what is the deadline given the circumstances/dates described above? Thank you so much in advance!
