Pavement condition surveys have traditionally been conducted <br />every three years and were last performed in 2017. <br />In the past, ratings were established by field staff visually evaluating pavement surface <br />conditions at selected sample locations and applying standard practices for identifying a <br />pavement condition index between 1 and 100. This approach can be subjective and inconsistent <br />due to variations between individuals performing the evaluation and the selected observation <br />locations. Staff has previously noted concerns with the consistency and accuracy of existing <br />pavement condition ratings. <br />In an effort to improve the data collection process, staff has solicited a proposal from IMS to <br />collect pavement condition ratings through automated vehicle mounted equipment using a laser- <br />camera array that eliminates subjectivity of the data collection process. Pavement data can be <br />easily transferred to the City’s ICON software which is used to store and evaluate the historical <br />data of Arden Hills’ street system. The automated process by IMS will also improve safety by <br />minimizing the time personnel are working on the streets collecting the necessary measurements <br />needed through visual evaluation. <br />CONSENT ITEM – 6D <br />MEMORANDUM
