- The data from the test well indicates too much current is moving to the front of the bulkhead wall due to the low resistivity of the soil behind the wall. A test distributed test system has been installed along A-dock 5 feet from the wall and 3 feet deep. At 3 feet, the cathodic sock is just above the tie-backs. We will have results next week. At this point there is high likelihood we will use the distributed system. There may also be some deep wells, but not as many as originally planned. The test results will provide further guidance for the final design. Also due to high conductivity, low resistivity of the soil, we will be able to run the system at lower power levels to achieve the desired results (less cost). Also the distributed cathodic system will not require venting, so less impact on the yards.
- We have pricing on the new coating material (TZ-904) at $95/gallon. The original application company Cooley is not interested in working with the new material, so we are getting bids from 2 new companies. One company can't start until next year, the second company Palacio Coating based in Texas is available now and came out to see the bulkhead to finalize their bid. The applicators must be trained and certified to work with this coating system and also use specialized pressure and heating equipment to meet the specifications. Steve Williams (coating quality consultant) is reviewing all the details. We should have a firm bid by the end of next week.
- The Final design Build proposal is on hold until the cathodic testing is completed and we make a coating contractor decision.
- SPC built a foam board mockup of the rectifier. Trent will paint it a landscape green and Myron will put it in a couple of locations and photograph it to share with homeowners next week.
