I have a contract with an Arkansas municipality...City of Texarkana, AR for a road reconstruction project. The value of the contract is approximately $700,000, and we are bonded with payment and performance bonds. The project is funded through a federal grant. Our first payment application was submitted on 08/15/2019 for $151,261.85. The second payment application was submitted on 09/13/2019 for $75,089.86. To date, we have received no payments. City representatives indicate that they are waiting on grant funds, that they have no way to know when those will be received and that they have no way to pay until received. What options do I have to force payment? How do I protect myself against complete non-payment should these funds never become available? Otherwise, is it possible that interest is due for these late payments?
