If you determine that an amendment or time extension may be required for your contract, you should contact your TWDB contract manager and formally submit a request in writing to justify the amendment.  The TWDB will carefully consider the need for the amendment and determine if it is required.  Be advised that requests for amendments should be submitted no later than three months prior to the expiration of the contract – to allow sufficient time for consideration and processing.  For more information, please contact David Carter at 512.936.6079 or david.carter@twdb.state.tx.us.
