Ga. Code § 46-3-35
Where, during any public highway construction, any temporary precautionary measure is required by this part to guard against accidental contact with high-voltage lines that are located upon public highways or roads which are owned by this state or a county thereof and which are located outside the corporate limits of any municipality, the expense of such temporary precautionary measure shall be borne by the owner or operator of such lines, provided that such construction is undertaken pursuant to a permit issued by the state or county, for which permit neither the state nor the county received consideration. The person responsible for the work nevertheless shall not commence any work until he has given notice as required by Code Section 46-3-34 and the safety precautions required by Code Section 46-3-33 have been effected.
