<strong>Current</strong> Deficiencies:<br />
1.) No evaluation <strong>of</strong> existing system prior to overcoating<br />
2.) No set evaluation program<br />
a.) Overcoating<br />
b.) Removal<br />
3.) No evaluation <strong>of</strong> failure mechanism<br />
4.) Programming <strong>of</strong> Bridge Maintenance schedule<br />
5.) Is it really cheap? Premature failures requiring rework before<br />
scheduled time to recoat.<br />
Constraints <strong>of</strong> the Program:<br />
Does calcium sulfonate mask cracks that would be seen with other coating<br />
systems?<br />
Money – Limited resources – Do more with less.<br />
Planning for the effective use <strong>of</strong> the money.<br />
Effective / appropriate surface preparation<br />
Prioritized maintenance<br />
Manpower / training / equipment<br />
Inability to dispose <strong>of</strong> power wash water – If power washing were to be used.<br />
Define / Evaluate Options:<br />
Establish a planning program<br />
Maximize product potential (use product at the right place at the right time)<br />
Attempt to receive more money for the program.<br />
Optimize the money available.<br />
Re-evaluate environmental requirements for wastewater from power washing<br />
Recommend New Practices:<br />
Optimize local maintenance crews from the reorganization. Establish a pilot<br />
program for coatings to plan and prioritize coating operations and analyze new<br />
technology<br />
