Relating to the requirement for payment bonds from certain public work contractors.

HB 643 requires public work contractors to provide payment bonds for certain government construction projects. It mandates payment bonds for contracts exceeding $50,000 with municipalities or transportation boards, and for contracts over $100,000 with other government entities. The law applies only to contracts where bidding begins on or after September 1, 2025, and does not affect existing contracts. This change ensures contractors provide financial guarantees to protect workers and suppliers from nonpayment. The bill directly affects contractors working on public infrastructure projects across Texas.
