D.C. Mun. Regs. tit. 27, r. 27-2710
The District shall require each contractor to obtain insurance, by purchase, for the risks to which the contractor is exposed, except when the contract specifically relieves the contractor of liability for loss of or damage to District property.
The contracting officer shall have the right to disapprove the purchase of any insurance coverage not in the best interests of the District.
Insurance shall be mandatory when commingling of property, the type of operation, circumstances of ownership, or conditions of the contract make it necessary for the protection of the District.
When the District requires a contractor to provide insurance coverage, the policies shall contain an endorsement that any cancellation or material change in the coverage or terms and conditions of the coverage shall not be effective unless the insurer or the contractor gives prior written notice of the cancellation or change to the District in the manner required by the contract or the contracting officer.
When the District requires or approves insurance to cover loss of or damage to District property, it may be provided by specific insurance policies or by inclusion of the risks in the contractor's existing policies. The policies shall disclose the District's interests in the property.
The Director may establish risk-pooling arrangements. These arrangements shall be designed to use the services of the insurance industry for safety engineering and the handling of claims at minimum cost to the District. The agency responsible shall appoint a single point of contact for each arrangement.
The contracting officer may specify insurance requirements under fixed-price contracts, as follows:
Employee group insurance plans shall not be reimbursable under cost-reimbursement type contracts unless the plans have first been approved by the contracting officer and are otherwise deemed reimbursable under the terms of the contract. Whenever an approved plan is materially changed during the course of the contract, the plan shall be resubmitted for approval, and no costs shall be reimbursable unless approval of the revised plan has first been obtained.
Group insurance plans under § 2710.8 shall provide for the District to share in any premium refunds or credits paid or otherwise allowed to the contractor. In determining the extent of the District's share in any premium refunds or credits, any special reserves and other refunds to which the contractor may be entitled in the future shall be taken into account.
