Questions and Answers

1. Sheet 863-208-60105 Note 4 discusses buoys with anchoring mechanism are located in the drawing. Neither the set of drawings nor the specification show any buoys with anchoring system. Please clarify if the buoys with anchoring system are requirements to this contract; if they are, please provide sufficient information.

Answer: No permanently anchored buoys are required for this project.

2. Reference drawing 863-208-60113, Detail 2 and Note 8 show Pipe Saddle, bolts and fastener are stainless steel. Specification section 09 63 20 -12 Coatings, Tabulation 2, states that pipe saddle and associated fasteners shall be coated with Epoxy/ Polysiloxane. Please clarify the coating requirement.

Answer: Drawing 863-208-60113, and the drawing package in general, dictate the specific materials required for parts. Stainless steel parts shall not be coated. Galvanized carbon steel parts shall not otherwise be coated. Only non-galvanized, carbon steel parts shall be coated.

Revised Specification Section 09 96 20 has been updated to clarify and is attached
