Design requests, how made — marking location required

1. Any person may make design requests by contacting the notification center. Such design requests shall include all information deemed necessary by the notification center to complete the notice, including the identification of the person and a description of the location of the project being designed and other information similar to that required of excavators under section 319.026. 2. Design requests shall be made to the notification center at least five working days before the date the person has requested receiving the information from the underground facility owner. Upon receipt of a design request, the notification center shall inform the person of the name of all notification center participants to whom the notice will be transmitted and shall promptly transmit such notice to the appropriate underground facility owners. 3. Every underground facility owner who receives a design request shall mark the location of the facility, or contact the person making the request, within five working days after the date the notice was received from the notification center. If the person making the request was contacted as an alternative to marking location, the person and the underground facility owner shall mutually agree on a schedule and method for providing the information, provided that the facility shall be marked within five working days if the facility owner and the person making the request are unable to agree. 4. No excavation may be commenced based upon information received through a design request. Obtaining information through a design request shall not excuse any person commencing an excavation from making notice and obtaining information under sections 319.025 and 319.026 concerning the possible location of any underground facilities which may be affected.
