Training for persons selecting process after field evaluation is complete Dedicated budget for coatings (no creep) Develop a best practice for chloride mitigation 61
Program: Contract Maintenance System: Ca Sulfonate, System G or H Deficiency / Issue Recommendation Impact Implementation Cost Benefit Evaluation Program Preliminary visual inspection 1 Utilize industry in development of Initial cost to train. & evaluation the program Existing coatings need to have adhesion checked, chloride levels Utilize NACE, SSPC or Consultant training programs Long term cost would save money Uniform analysis of % rusting (from SSPC) Internal program for visual inspection / evaluation Special crew to do evaluation based on annual inspections Internal training program for test methods. Trained inspectors Use NACE or other trained inspectors for references Needs to be standardized statewide Eliminate project planning scope creep Chloride Mitigation Pressure wash 2 Collection of rinse water / EPA issues Appropriate pressure levels and flow rates Define appropriate end result for chloride levels Chlor-rid 5 Requires pressure wash before and after application or blast cleaning after application. Long Able to plan scope of project closer to contract cost $ $$ $$ - Long-term performance is increased $$$ - Cost to performance ? 62
