87-60 Final Report
Deterioration and Cost Information for Bridge Management
Final report for CDOT project 87-60 to assemble deterioration, action and cost data for CDOT's Pontis BMS preservation model. The project will populate data tables in Pontis, operate the preservation model and evaluate the quality of outcomes, and establish automated procedures for ongoing preparation and use of construction cost data in CDOT's Pontis system.

Feasibility of a Management System for Retaining Walls and Sound Barriers
Blueprint for asset management systems for retaining walls and sound barriers. Wall/barrier management systems are implemented within existing software for bridge management such as AASHTOWare's Pontis management system. The project developed inventory record for walls and barriers, elements for walls and barriers, the use of components for hidden elements of walls, condition states, and appraisals, together with initial recommendations on inspection practices and intervals.
