2. At the Owner's option, remove the interior caulking from the vertical and <br />horizontal construction joints on the exterior wall. T here are eight (8) vertical <br />construction joints and two (2) horizontal joints. The cost of this item is not <br />included in this cost estimate. If the intent is to eliminate leakage out of the <br />reservoir, this item is not required. The Owner may choose to perform this to <br />minimize the likelihood and effects of corrosion on reinforcing steel at these <br />joints. <br />3. If, during the repair of the exterior wall construction joints, additional obvious <br />cracking is discovered, this should be repaired by saw -cutting and caulking <br />similar to that described in 3.1.2. <br />Interior Wet Coating - Concrete <br />IaM does not recommend any coating repairs or replacement at this time. Following <br />interior construction joint caulking replacement and exterior roof coating, the reservoir <br />can be tested for leaking. If excessive leakage is found, the reservoir can be drained next <br />year for interior coating removal and crack repair. At that time, interior coating of the <br />walls and floor by installation of a polyurea coating system would be at the Owner's <br />option, when its cost can be evaluated against potential leakage following crack repairs. <br />Interior Wet Coating - Piping <br />Perform the abrasive blasting and painting of the steel piping and appurtenances as <br />identified in KLM's report. <br />Exterior Structural Repairs <br />Perform the structural modifications as identified in Sections 3.4.1 to 3.4.5 of KLM's <br />report. In addition, perform the following: <br />1. Perform repair of spalling and air voids of the exterior edge of the concrete roof <br />by hand application as described in Appendix C. <br />2. Replace the caulking at the butt joints of the flashing as seen in photo 48 of <br />KLM's inspection report, and between both the inner and outer joints between the <br />flashing and the concrete. <br />Exterior Coating — Roof <br />Following exterior structural modifications, coat the entire roof with a polyurea coating <br />system as identified in Section 3.5 of KLM's inspection report. <br />Exterior Coating — Roof Edge Concrete and Outer Flashing <br />In addition to coating the top of the roof with a polyurea coating system, coat the outer <br />face of the concrete roof and flashing with an acrylic coating system. <br />
