48 CFR § 52.237-6 - Incremental Payment by Contractor to Government.
As prescribed in 37.304(c), insert the following clause in solicitations and contracts for dismantling, demolition, or removal of improvements (a) if the contractor is to receive title to dismantled or demolished property and a net amount of compensation is due the Government, and (b) if the contracting officer determines that it would be advantageous to the Government for the contractor to pay in increments, and for the Government to transfer title to the contractor for increments of property, only upon receipt of those payments:
(a) The Contractor shall perform the work called for under this contract and within __ days of receipt of notice of award, unless otherwise provided in the Schedule, and before proceeding with the work, shall pay ____ [fill in amount]. Thereafter, the Contractor shall make payment to the Government in the amount and frequency specified in the Schedule. Checks shall be made payable to the office designated in the contract and shall be forwarded to the Contracting Officer.
(b) Upon the Government's receipt of each increment of payment, the Contractor shall receive title to such property as the Contracting Officer determines to be fair and reasonable for that increment of payment. Upon receipt of the Contractor's final payment, all title that has not passed to the Contractor shall vest in the Contractor, unless specifically designated in the Schedule as being retained by the Government. The Government shall not be responsible for the condition of, or any loss or damage to, the property.
(c) The Contractor shall promptly remove from the site all property acquired by the Contractor. The Government will not permit storage of property on the site beyond the completion date. If the Contractor does not wish to remove from the site any of the property acquired, the Contracting Officer may, upon written request, grant the Contractor permission to leave the property on the premises. As a condition of the granting of this permission, the Contractor agrees to waive any right, title, claim, or interest in and to the property.
