| 1 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (STRUCTURAL) | Clean any PV module with water or not aggressive products used for the glasses cleaning | Can the USG please clarify if the water for this requirement will be provided to the contractor or if bidders need to provide their own tanks and water supply? | The Government will provide water availability at the faucet. See PWS 3.3 | The Government will provide water availability at the faucet. See PWS 3.3 | No issue with Answer. |
| 2 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (STRUCTURAL) | Clean any PV module with water or not aggressive products used for the glasses cleaning | If water is to be provided, can the USG clarify where the connection points will be located? | Ground floor near each technical room. | Ground floor near each technical room. See PWS 3.3 | No issue but suggest providing more specificity here. How many available total? Where are they specifically situated? Also revise within PWS itself. |
| 3 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (STRUCTURAL) | Clean any PV module with water or not aggressive products used for the glasses cleaning | If water is to be provided, will hoses also be provided? | No, this is a contrcator's responsibility. | No, this is a contractor's responsibility. See Revised PWS 3.3 | Misspelling; change to "contractor." |
| 4 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Check and Verify with Thermo-Camera the status of the main electrical panels and inverters connections | Can the USG clarify if this requirement can be met through a sampling protocol or if each panel must by verified with thermal imaging? | 100% Inspection is required | 100% Inspection is required. See DELIVERABLE 0014 | I would change verbiage to repeat actual words in the question so there is no confusion i.e. "100% inspection is required therefore each panel must be verified with thermal imaging." This should also be revised in PWS itself. |
| 5 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Check and Verify with Thermo-Camera the status of the main electrical panels and inverters connections | If every panel must be imaged, are contractors required to provide the resulting images for each panel or only those with identified faults/defects? | Only the ones defected | Only the ones defected. (*DEFECT: "a fault or problem in something"). See DELIVERABLE 0014 | Same comment as the above - I would change answer to, "Contractors are only required to provide images of panels with identified faults/defects." Also revise in PWS. |
| 6 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Check and Verify with Thermo-Camera the electrical boxes and panels present on the roof | Can the USG clarify if this requirement can be met through a sampling protocol or if each box/panel must by verified with thermal imaging? | 100% Inspection is required | 100% Inspection is required. See PWS Tab.n.2 Pos#9 | See #4 above. I would change verbiage to repeat actual words in the question so there is no confusion i.e. "100% inspection is required therefore each panel must be verified with thermal imaging." |
| 7 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Check and Verify with Thermo-Camera the electrical boxes and panels present on the roof | If every box/panel must be imaged, are contractors required to provide the resulting images for each panel or only those with identified faults/defects? | Only the ones defected | Only the ones defected. (*DEFECT: "a fault or problem in something"). See DELIVERABLE 0014 | Same comment as the above - I would change answer to, "Contractors are only required to provide images of panels with identified faults/defects." Also revise in PWS. |
| 8 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Verify the correct numbers of serial numbers for each panel installed reporting discrepancies | Will the USG be providing contractors with a list of all serial numbers to verify? | The serial numbers will be privded under request. The contractor is not responsible to check them. Only in case of replacements they shall be verified. See PWS 5.2.1.3 | Verify the correctness of serial numbers for each newly installed panel reporting discrepancies. See PWS 5.2.1.3 | The word "provided" is misspelled. Furthermore, I am confused as to the answer provided. I am not clear on the following: 1) Are the serial numbers necessary for the contractor to have or not? 2) If the answer is yes, can they just be provided - why do they have to be requested? 3) The PWS 5.2.1.3 does not discuss serial numbers, so I am not sure why this paragraph is cited here. Please explain more clearly. Also revise in PWS. |
| 9 | Attach 01 - PWS | 23 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Verify the correct numbers of serial numbers for each panel installed reporting discrepancies | If no master serial list will be provided can the USG clarify that contractors will be required to develop a baseline list as part of the deliverables to this contract? | No | Verify the correctness of serial numbers for each newly installed panel reporting discrepancies. See PWS 5.2.1.3 | Again, I am not clear on this answer. Will the master list of serial numbers be provided or not? State this as a full sentence and be more specific. Also revise in PWS. |
| 10 | Attach 01 - PWS | 24 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Check and Verify with Thermo-Camera the surface of any PV module to evaluate potential deficiencies | Can the USG clarify if this requirement can be met through a sampling protocol or if each PV module must by verified with thermal imaging? | 100% Inspection is required | 100% Inspection is required. See DELIVERABLE 0014 | 100% of what is required? See number #4 above. The vendor's question has not been clearly answered. I recommend stating, "Every panel must be inspected using xxxxx, in order words 100% Inspection is required." Also revise in PWS. |
| 11 | Attach 01 - PWS | 24 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Check and Verify with Thermo-Camera the surface of any PV module to evaluate potential deficiencies | If every PV module must be imaged, are contractors required to provide the resulting images for each panel or only those with identified faults/defects? | Only the ones defected | 100% Inspection is required. See DELIVERABLE 0014 | Same comment as #7 above - I would change answer to, "Contractors are only required to provide images of panels with identified faults/defects." |
| 12 | Attach 01 - PWS | 24 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Insulating tests for the single plants composing the system IAW CEI 82-25 requirements (chapter 15.2) | Can the USG please clarify the definition of 'system' in regards to this requirement? | Insulating tests is required for each section composing a PV system. | Insulating tests is required for each section composing a PV system. A “system” is technically assumed as the entire PV plant and related components installed on each of below listed facilities. See Technical Drawings with these constructive details, where the sections of each system can be identified (reference to PWS Enclosures #1 #2 #3 #4) | Again, the answer has not been clearly answered. The vendor's question is - What constitutes a system. Therefore, please state, "A PV system consists of xxxxx." Also revise in PWS. |
| 13 | Attach 01 - PWS | 24 | 5 | 6-Months STANDARD MAINTENANCE OF PV SYSTEMS (ELECTRICAL) | Measure the Electrical Parameters of any PV array, comparing the measures taken with the ones displayed by the inverter’s panel board.
