"Sec. 1   RCW 47.20.785 and 2006 c 37 s 1 are each amended to read as follows:
     (1)(a) The department of transportation ((may use)) shall consider using the design-build procedure for public works projects over ten million dollars where:
     (((a))) (i) The construction activities are highly specialized and a design-build approach is critical in developing the construction methodology; or
     (((b))) (ii) The projects selected provide opportunity for greater innovation and efficiencies between the designer and the builder; or
     (((c))) (iii) Significant savings in project delivery time would be realized.
     (b) A written explanation must be provided, upon request by the transportation committees of the legislature or by the office of financial management, to explain why the design-build procedure was not selected for public works projects over ten million dollars.
     (2) ((To test the applicability of the design-build procedure on smaller projects and specialty projects, the department may conduct up to five pilot projects on projects that cost between two and ten million dollars.)) The department shall periodically evaluate ((these pilot projects)) the design-build procedure, including public works projects less than ten million dollars, with respect to cost, time to complete, efficiencies gained, if any, and other pertinent information to facilitate analysis regarding the ((further)) use of the design-build process ((on projects of this size))."
