Articles 2.2.2.1, 2.2.2.2, and

2.2.2.3 “Wiring” We normally weld this type galvanic anode system directly to the piling. Are these requirements only related to the single test station specified, or do you expect all anodes to be wired? Does this requirement only apply to soil anodes for piping, if applicable?

The connection system is dependent on the manufacturere and selected products. Wiring requirements are defined and are applicable if the selected manufacturer system requires it. There are no anodes required for utility piping.

71 26 42 13 2.2.2.5 Article 2.2.2.5 “Resistance Bond Wires” Is welding sheet pile interlocks or welding the wale to the sheet pile within the concrete cap sufficient in lieu of thermite welding copper wires across interlocks?

Yes, this should be submitted as a variation in accordance with 01 33 00 for consideration if that is the method used to achieve this aspect of peformance requirement.

72 26 42 13 2.2.4 Article 2.2.4 “Permanent Reference Electrodes” This article calls out copper sulfate permanent reference electrodes. Copper sulfate reference electrodes are not stable in salt water. May silver chloride permanent reference electrodes be substituted instead?

This may be acceptable dependent on contractor system design. Submit as part of the shop drawing design, or independently as appropriate and comply with the vairation requirements of 01 33 00 for consideration.

73 S-303 Please provide a typical pavement section for the areas adjacent to the proposed Power pedestal Foundations and Electrical Conduit Support Posts with Concrete Foundations.

75 7 31 62 13.20 1.8.4 Specification section states, "Registered Professional Geotechnical Engineer......is to observe test pile installation and production pile installation as specified herein." Spec Section 01 45 00.00 23 for the Geotechnical QC Team references weekly inspection and surveillance. If these spec sections are referring to the same position please clarify if continuous observation is required during driving or just a weekly inspection of previously driven piles is required.

Geotechnical Engineer is required to be on site during test pile installation.

Production pile QC is defined in section 01 45 00 within the Geotechnical team. Provided this individual meets the qualifications as defined in both sections they could be the same individual. This would be subject to submittal approval as defined in the contract.

76 26 42 13 2.4.1 Article 2.4.1 “Non-Destructive Testing of Anodes” describes a test procedure to establish the anode potential in fresh water. Aluminum anodes are specified, but aluminum will passivate in fresh water. This test is not appropriate for aluminum. Failure of this test is expected for any aluminum anode. Aluminum needs salt water to remain active. The aluminum potential will vary depending on the salinity of the water. Can we modify the procedure to verify the native anode potential in the brackish Severn river water?

This is dependent on contractor material and system design choices.

Submit proposed plan in accordance with shop drawings and calculations required in the specification. Note, the actual site conditions have highly variable salinity which must be accounted for in the contractor system design, testing, and placment into operation.

77 26 42 13 2.4.2 Article 2.4.2 “Destructive Testing of Anodes” It is standard practice for marine anodes to be directly welded to the piling and not be wired. This specified test appears to be unnecessary. Can this requirement be waived/removed?

This is dependent on contractor material and system design choices.

Submit proposed plan in accordance with shop drawings and calculations required in the specification. Identify variations from specification as required in section 01 33 00.
