II Scope of Services Performed by DIXON: <br /> 1. Clean interior surfaces of the tank with high pressure water. Cleaning is <br /> necessary for the Professional to be able to remove all the mud This allows <br /> DIXON the ability to see any deterioration of the steel,pitting, etc. High pressure <br /> water also enables DIXON to perForm a very low cost adhesion test on the <br /> remaining coating. DIXON would notice if the coating is wavering,etc.,which <br /> would indicate very poor adhesion and anticipated failure. The amount of mud � <br /> removed from a torus tank depends upon the Owner's preference,time allotted, � <br /> and cleaning equipment available. ' <br /> 2. Inspect the tank's interior coating for remaining intactness and anticipated life. I <br /> Review all interior girders and appurtenances for possible structural damage from <br /> icing or corrosion. <br /> 3. Review all interior surfaces for conosion and/or damage,and qualify damage for <br /> repairs. All repairs are to be quantified by e�rapolation of a measured area. All <br /> quantities are estimates(usually high)because conosion will continue between <br /> inspection and repair. <br /> 4. Inspect the exterior coating and perform cross-cut ad.hesion tests where coating <br /> adhesion is questionable. If it is evident that repainting is not necessary for <br /> several years,no destructive adhesion tests will be performed <br /> 5. Review all exterior appurtenances for damage due to corrosion. <br /> 6. Review a11 safety requirements for ladders,cages, etc. (interior and exterior). <br /> 7. Review all health aspects of the tank, including screening of the vent, overflow <br /> pipe,and other possible contamination sources. <br /> 8. Review the exteriar of the exposed foundations. <br /> 9. Prepare a report documenting all items found and recommendations for repair, <br /> including budgetary items. The engineering report is to include: Conclusions and <br /> recommendations,base report,digital photographs,and descriptions. <br /> 10. Chlorinate the tank per AWWA Method Na. 3 C-652-02. This item may be <br /> relocated to the Scope of Services Performed by Owner, if thus contracted. <br /> -3 - <br />
