1. Are we to included replacing the rectifiers at these missile sites in our quotes? On page 4 of 38 on the solicitation it reads “use existing”. In the past we’ve always just replaced them. We would also like to know if new junction boxes are required as well.
Per the Page 3 of the Statement of Work under “4. SCOPE OF WORK” section, the rectifier is to be replaced.

There is fencing at I-06, I-08, L-01, and L-04 that will need to be disassembled/reassembled.

Typically 5’ between the wells, and no more than 25’ from the rectifier.
5. Can you send us a drawing or pictures of the existing rectifier/junction box mounting, so we can determine what’s required for the new rectifier/junction box?
See the Detail for the rectifier/junction box mounting on Sheet 5 of 5 in the plans.
6. Is it the intention that all wells should be installed prior to winter shutdown in 2021?
Yes, but this is weather dependent.
7. Can the wells be installed in succession prior to installing the rectifiers/junction boxes, or shall each site be completed prior to moving to a new location?
Each site shall be completed prior to moving to the next site.
8. What is the input AC requirement for the rectifier?
Per the Page 12 of the Statement of Work under “15. EQUIPMENT FOR RECTIFIERS AND SHUNT BOXES” section, the rectifier model is specified and shall be installed according to the SOW and the rectifier manufacturer recommendation.
