141 APPENDIX 3--PAVEMENT MANAGEMENT DATA COLLECTION DEMONSTRATION AND ORAL PRESENTATION Vendors on the short list will be asked to make an oral presentation and to participate in a demonstration to collect specified condition data at ODOT control sites. ODOT scoring of vendor proposals will take into account the information presented in the proposal document, the oral presentation, and the results of the control site demonstration collection as described in this document. Control site data will be collected by the vendor between September 1, 2007, and November 30, 2007, at the vendor's expense. Any vendor that does not meet the requirements of the control site demonstration will be eliminated from further consideration. All short-listed vendors that meet the requirements of the control site demonstration will be asked to make an oral presentation displaying the company's services and results from the demonstration collection. Oral presentations will be scheduled in January 2008. Expenses incurred for the control site demonstration collection and oral presentation are the responsibility of the vendor; there will be no compensation from ODOT. Requirements related to the control site demonstration collection and oral presentation are as follows. Control Site Demonstration of Data Collection Capabilities Each short-listed vendor will be required to collect pavement data for the outside lane for the specified four control sites. The control sites are mapped and described below. Vendors should contact ODOT to schedule a specific day(s) for collection. An ODOT employee will accompany the vendor's representatives during the collection if requested. Sites may be run up to five times consecutively and up to five runs may be submitted for each control site.
