Del. Code Ann. tit. 29, § 6907
(a) An agency head may waive any or all provisions of this chapter to meet the critical needs of the agency as required by emergencies or other conditions where it is determined to be in the best interest of the agency. The agency head may determine an emergency condition exists by reason of extraordinary conditions or contingencies that could not reasonably be foreseen and guarded against. An emergency condition creates an immediate and serious need for materiel and/or nonprofessional services that cannot be met through normal procurement methods for the protection of public health, safety or property.
(b) In addition to the waiver provisions provided for in subsection (a) of this section, an agency head may waive any or all provisions of subchapter VI of this chapter to meet a critical need of the agency as required by an emergency or other condition where it is determined to be in the best interest of the agency. The agency head may determine a critical need exists by reason of conditions or contingencies that could not reasonably be foreseen and guarded against. A critical need creates a need for professional services that cannot be met through normal procurement methods.
