revise procurement for highway construction contracts.

SB 26 exempts highway construction contracts entered into by South Dakota's Department of Transportation (DOT) from standard state procurement rules. This means the DOT can bypass typical competitive bidding requirements when awarding these specific contracts. The bill amends existing law to clarify that DOT highway construction contracts are explicitly excluded from general procurement statutes. It directly affects the DOT and contractors working on state highway projects, streamlining their procurement process. The change focuses on administrative efficiency for highway construction, not altering the scope of work or funding.
