The dollar amount limits provided by this subsection shall be adjusted on February 1 each year based on the percentage increase or decrease of the Detroit consumer price index for the 12-month state fiscal year ending the preceding September 30. The adjustment shall be determined by multiplying the percentage increase or decrease in the Detroit consumer price index times the dollar limitation provided by this subsection and adding the product to the dollar limitation for the previous year as adjusted by this subsection.

(3) The state administrative board may require that the state transportation department file periodic reports with the board on those contracts or authorizations for extra work or labor, or both, that do not require approval by the state administrative board. The state administrative board shall establish by resolution standards and procedures for these periodic reports.

(4) The state transportation department, without approval of the state administrative board, may contract with a person, business, or governmental unit described in subsection (1) or (2) in a reasonable amount under conditions that the department determines will require emergency action if a written report of the nature of the contract and the emergency are transmitted immediately to the state administrative board after the contract is entered into.
