| Questions | Answers |
| Which transformers will need to be done on the weekend in order not to impact buildings or systems? | Weekend work has to be pre-approved by Cannon AFB due to base manning it may or may not be permitted. However, if it is permitted we will coordinate weeks in advance and identify proper transformers. (Mr. Harlow to verify) |
| Will one of the alternate transformers be included in the base bid since TCNST1 has already been removed and if so, which one? | T135B-TH |
| Can the bush around the T75 be removed? If so, are we responsible to remove it? | Yes, Cannon AFB is working on have the grounds contract complete this. |
| Can the large overhanging branch above T155 be removed? If so, are we responsible to remove it? | Yes, Cannon AFB is working on have the grounds contract complete this. |
| Attachment 1 - SOW | |
| Statement of Work 3. General Provisions I. Can you provide a DD Form 1354? | Yes it will be provided |
| Statement of Work 3. General Provisions J. Airfield- Can you provide the length of time for the airfield access trainings 1. & 2.? | Airfield driving training takes less than a day to complete. It is done in Base Ops building, at no charge.The only Xfrmr with airfield access would be T2360-TH |
| Statement of Work 3. General Provisions K. Phasing Plan- Is this required? I ask because we are not familiar with which buildings and systems will be affected so putting together a Phasing Plan will be difficult. | Yes, a phasing plan is required, information such design/delivery times per transformer, and installation time per transformer, haul route, and/or street closures. |
| Statement of Work 3. General Provisions K. Phasing Plan-Is the serving utility the City of Clovis electric or Xcel Energy? | Xcel is our utility but CE is in charge of everything on the load side of the Substation |
| Do any of the transformers have PCBs? If there are PCBs pesent, what is the disposal process? | No, transformers on base do not have PCB's. Report will be provided. |
| Please provide all available PCB testing data for the transformers | A copy is attached/provided. |
| 4. Specific requirements 3. This asks for us to assume additional primary wiring will need to be pulled. It would be better to handle this as a change order in the field if required. Many of these transformers appear to have good primary cabling with enough length to reuse with the new transformers. Is that acceptable? | Yes it is acceptable, a change order will suffice. |
| If it is not, please provide the locations of the existing sources for the transformers with pictures of the inside showing terminations, existing conduits and the footages and routing of each. | Not applicable. |
| Statement of Work 5. Project meetings B. Weekly Meetings- we don't intend to have a jobsite trailer. Can these meetings be held via Zoom or conference call or will a PM be required to be onsite for them? | Yes, conference call as well as on the jobsite, and at least a superintendent be available. |
| Statement of Work 7. Project Closeout- Are electronic copies acceptable in place of hardcopies and CDs? | Yes that is acceptable. |

How do we handle the Interim DD Form 1354? | The Interim DD form 1354 can be done at anytime, even halfway through the project. The Interim DD Form 1354 is the same form as the initial or draft DD Form 1354, except you update it as you go until you finalize it. |
| Page 5 of 9 of the Statement of Work tells the contractor to assume additional Primary wire will need to be pulled to each location from the existing source. What is the 15kV cable specification, Cable Size, and where do we pull from for each location? | 15 KV MV UD Cable TRXLP 100% insulation. Conductor size and pull location would be case by case. |
| Contractor assumes that on the Statement of Work Appendix A, the primary voltage for Priority 1 thru 12 shown on page 8 of 9 of the Statement of Work is 12470 as stated in specification section 26 12 19.10? | yes 12470 is the primary voltage |
