This chapter is promulgated to assure that contractors engaged in the improvement and construction of state highways possess the necessary qualifications as required by RCW 47.28.070. It is further intended to:

(1) Establish a method for determining a contractor's qualifications to undertake department work and for the retention of that qualification.

(2) Provide a means for contractors to enhance their prequalification status and bidding capacity through higher standards of performance.

(3) Increase the opportunity for a better relationship between the department and construction contracting firms.

(4) Provide for the award, denial, suspension, or revocation of qualification; denial of proposal issuance; and for a hearing procedure, if required, for such actions.
