S.C. Code § 10-1-100
All invitations for bid proposals for construction projects (but not including South Carolina Highway Department projects) issued by the State, its authorities, commissions, departments, committees or agencies, or any political subdivision of the State, shall set forth in the contract documents, to the extent they are reasonably obtainable by the public awarding authority, those provisions of federal, state and local statutes, ordinances and regulations dealing with the prevention of environmental pollution and the preservation of public natural resources that affect or are affected by the projects. If the successful bidder must undertake additional work which was not specified in the invitation for bid proposals or which are due to the enactment of new or the amendment of existing statutes, ordinances, rules or regulations occurring after the submission of the successful proposal, the awarding agency shall issue a change order, setting forth the additional work that must be undertaken, which shall not invalidate the contract. The cost of such a change order to the awarding agency shall be determined in accordance with the provisions of the contract for change orders or force accounts and that such additional costs to undertake work not specified in the contract documents shall not be approved unless written authorization is given the successful bidder/contractor prior to his undertaking such additional activity. In the event of a dispute between the awarding agency and the successful bidder/contractor, arbitration procedures may be commenced under the applicable terms of the construction contract under the provisions of Chapter 48, Title 15.
