(1) Except as provided herein, purchase by the Department of Transportation of commodities, including the advertising and awarding of competitive bids, shall be governed by chapters 283 and 287 and rules adopted by the Department of Management Services pursuant thereto. However, the provisions of s. 287.057 notwithstanding, the department may purchase parts and repairs valued at up to the threshold amount provided in s. 287.017 for CATEGORY TWO for the repair of mobile road maintenance equipment, marine vessels, permanent vehicle scales, and mechanical and electrical equipment for movable bridges, toll facilities including the Florida Turnpike, and up to the threshold amount provided in s. 287.017 for CATEGORY THREE for treatment plants and lift stations for water and sewage, and major heating and cooling systems without receiving competitive bids.
(2) If the department determines that an emergency exists in regard to the purchase of materials, machinery, tools, equipment, or supplies, so that the delay incident to giving opportunity for competitive bidding would be detrimental to the interests of the state, the provisions for competitive bidding do not apply; and the department may authorize or purchase such materials, machinery, tools, equipment, or supplies without giving opportunity for competitive bidding thereon. The department shall, within 10 days after such determination and purchase, file with the head of the Department of Management Services a written statement of the materials, machinery, tools, equipment, or supplies purchased and a certificate as to the conditions and circumstances constituting such emergency.
(3) When the department advertises for bids on a contract for supplies, materials, equipment, or other items needed by the department, specifications shall be drafted in such manner as will afford adequate protection to the state as to quality and performance, but specifications shall not be drafted in any manner which will preclude competition in bidding.
