Do Subcontractors have to provide Lien Waivers in Texas

As a GC I have always provided Conditional and Unconditional Lien Waivers to our clients on a commercial job. There is a new job that is coming up and the client is also requesting Conditional and Unconditional Lien Waivers from our Subs, Vendors, Manufactures, and pretty much anyone who will be tied to this job per payment request. In the state of Texas, are the lien waivers required from our Subs and vendors to submit to the client in request for progress payment asides from the Final payment? Thank you.
