(a) To assist counties, the comptroller of public accounts may develop, promulgate, and widely distribute forms, with instruction, for cost accounting for public improvements. The comptroller shall consult with large and small governmental entities and the construction industry prior to the promulgation of the forms and instructions.
(b) The cost accounting forms shall be simple and concise and capable of being completed by the counties at a minimum cost. The form shall provide a simple comparison of the cost of public improvements constructed by a county’s personnel, equipment, or facilities and a competitive bid submitted by the private sector.

(c) The forms and instructions promulgated and distributed shall provide for cost comparisons by all governmental entities, including but not limited to counties, municipalities, special districts, and any other such entities that construct public improvements in-house. The cost comparison forms, with instruction, shall be promulgated and distributed by May 21, 1994.
