About this file
This is a Questions and Answers document for Solicitation N6852026Q0001, an Annual Industrial Hygiene and Noise Survey requirement at NAS North Island. The government anticipates eight personnel across Similar Exposure Groups (SEGs): 2 blasters, 2 welders, 2 painters, and 2 blast cabinet operators. The contractor must perform personal dosimetry and area sound level mapping for noise monitoring across 10 personnel in 6 buildings (873, 39, C110, C121, M14, and 347). The contractor is responsible for ventilation surveys of 2 paint booths, 2 blast booths, 2 blast cabinet areas, and 2 weld areas, including evaluation of local exhaust ventilation (LEV) systems used during welding operations. Annual noise monitoring should be limited to noise dosimetry and sound level surveys of potential noise sources within each building. Laboratory analytical costs must be included in the contractor's quote, and the contractor must use an AIHA-accredited laboratory.
Building dimensions are provided for scope assessment: Bldg M13 (32'X16'X12'), Bldg 169 (27'X13'X9'), Bldg M-14 (26'X14'X9'), Bldg 201 (30'X15'X12'), Weld Shop 1 (39'X23'X13'), and Weld Shop 2 (28'X26'X30'). The government requires one day of monitoring per activity sampled and five days for statistical evaluations. Noise sources vary by location and include T-15s, spotting dollies, power plants, tow tractors, forklifts, cranes, jet noise, painting equipment, and blasting equipment. Surveys are required yearly, with the last survey performed in December 2024, and contractors have discretion on timing throughout the year.

Sheet1
| Question | Answer | |
| 1) | Anticipated Sample Counts & SEGs - Approximate headcount per Similar exposure group (SEG) per location (Blasters, painters, welders). | We anticipate a total of eight (8) personnel. The breakdown includes 2 blasters, 2 welders, 2 painters and 2 blast cabinets operators. |
| 2) | For the annual Noise Survey across all buildings stated, do you prefer: Full-shift personal dosimetry only or a mix of personal dosimetry and area sound level mapping? | Monitoring Preference: We would prefer a mix of personal dosimetry and area sound level mapping |
| 3) | When was the last time the paint/blast booths were evaluated and to what standards? | The last time the paint/blast booths were evaluated was 04 December 2024. |
| 4) | How many booths are needed to be tested? | See question 1 |
| 5) | For personal exposure monitoring described in Items a–c, please confirm the total number of personnel requiring personal air monitoring at each building | See question 1 |
| 6) | The solicitation references use of an AIHA-accredited laboratory. Please confirm if laboratory analytical costs should be included in the contractor’s quote, or if they will be covered by the Government. | The laboratory analytical costs should be included. |
| 7) | For Item d (request air flow test for all paint and blast booths): | |
| a.) Is the contractor expected to perform ventilation surveys, or to coordinate these services with an on-site POC that maintains these systems? | Yes the contractor is expected to perform ventilation surveys. | |
| b.) If the contractor is to provide these surveys, please confirm the total number of paint booths and total number of blast booths to be evaluated. | 2 Paint Booths, 2 Blast Booths, 2 Blast Cabinet areas and 2 Weld areas. | |
| c.) Additionally, welding operations were included in the tasks identified for personal air monitoring, if local exhaust ventilation (LEV) systems are used during welding tasks, should we include evaluation of these LEV systems as part of our scope and quotation or is the ventilation surveys limited to paint and blast booths only? | Yes include evaluation of the LEV system. | |
| 8) | For annual noise monitoring, please confirm the total number of personnel requiring noise dosimetry. | 10 personnel working across 6 different buildings 873,39,C110,C121, M14, and 347. |
| 9) | Is the annual noise monitoring limited to noise dosimetry, or are sound level surveys of potential noise sources within each building also required? | Annual noise monitoring should be limited to noise dosimetry amd sound level surveys of potential noise sources within each building. |
| 10) | How big are the buildings on the subject building list in the SOW (e.g., square footage, occupancy levels, relevant work group job titles and numbers per work group). As to occupancy levels and work group job titles and numbers, we need to understand this for Similar Exposure Group (SEG) representative monitoring scoping. It is challenging to provide a competitive quote without context as to size of these facilities. | Bldg M13- 32'X16'X12', Bldg 169- 27'X13'X9', Bldg M-14 26'X14'X9', Bldg 201 30'X15'X12', Weld Shop 1- 39'X23'X13', Weld Shop 2- 28'X26'X30'. |
| 11) | Is there a general level of monitoring that is expected, for example, 1 day of monitoring per activity sampled, or 3 days for statistical evaluations? | One day of monitoring and 5 days for statistical evaluations. |
| 12) | What types and rough numbers of noise generating equipment that are the subject of noise surveys are there in each of the listed locations. Again we need to understand the scope of the facility to determine how insensitive the monitoring will need to be. | Bldg 873 (T-15s number of units vary) Bldg 39 (Spotting dollies, Mobile Power plants, Towtractors and Forklifts/ number of units vary) C-110 (Forklifts Cranes and jet noise/ number of units vary) C-121 ( Forklifts and frequent jet noise) M-14/PS169 (Painting Equipment) 201/M-13 Blasting Equipment |
| 13) | Do we have discretion as to when surveys can be performed throughout the year, or is there a set schedule that is needed to be adhered to? | These surveys are required yearly. Our last survey was performed in December of 2024. |
