A1. This is a one-time service.

Q2. Section 1.3.1 How many buckets does the government want? Where does this cost go on the pricing sheet?

A2. All 88 buckets shall be replaced (SOW updated). Cost goes under “Supplies” under “Range Cleaning.”

Q3. Section 1.3.2 asks us to replace the DCU filters as needed. However there is no line item in the pricing sheet for this aspect of work. Please confirm if these filter replacement will be required. If so please provide the part numbers.

Q4. What type of rounds are you firing? What percentage is frangible?

A4. A mixture of caliber of rounds to include 9, 556, 40, 45. Appx 75% frangible Q5. There is no recycling stream for range floor dirt, storm drain sludge, incidental material and debris. Please confirm if this waste will be disposed of as hazardous waste.

A5. Yes, this will be considered hazardous waste, if lab analysis confirms it. all waste must be disposed of IAW Federal/State/Local law. It is incumbent on the contractor to make a determination, quantitatively or qualitatively, as to the nature of wastes generated by their activity. See Question #8 for more details.

Q6. Typically the HVAC filters are replaced during a duct cleaning. This is because we have to remove them to clean the unit. But there is no verbiage about replacing filters. So as written the dirty filters will re-contaminate the HVAC system. However section 1.10 says we are certifying the disposal of filters A6. There is no HVAC onsite Q7. Section 1.4 What are the empty containers that are not reusable?

A7. Needs to be treated as hazardous Q8. What items will need to have a TCLP test?

A8. TCLP testing for lead was done in the past on 4 or 5 waste streams to determine the levels of lead in the waste. Waste streams include the storm water sludge from the pit, the debris from the cleaning of the walls and floor, the debris from the trough and the debris from the baghouse and 55 gallon drum. It is incumbent on the contractor to make a determination, quantitatively or qualitatively, as to the nature of wastes generated by their activity.

Q9. The pricing sheet includes a linear footage for duct work cleaning. To accurately provide this information, we will need duct drawings for the facility, If the DCU filter are being replaced does the DCU need to be HEPA vaced?

A9. Yes, once the filters are removed, the unit should be cleaned up with a HEPA vacuum to get any residual contaminants. See drawings attached in Fedbizops.

Q10. Section 1.3.6 Are you wanting to implement the NADCA standards for duct cleaning https://nadca.com/ A10. NADCA is for “indoor air quality” and is not applicable in this case.

Q11. How many grates need cleaned?

A11. See drawings of facility attached in Fedbizops Q12. My question on the wipe sampling pertained to the size of the template. Industry standards for wipe samples are generally 100 cm2 (10 cm x 10 cm) for any industrial hygiene study. Does the 911th want the template wipes in square foot (12” x 12”) templates or would you prefer the 100 cm2?

A12. The sample template is to be 12” x 12” Q13. With regard to wipe samples, there was mention that several samples were to be taken on grated surfaces. Wipe samples need to be taken from smooth, non-porous surfaces. Can you clarify if the sample areas include any grated areas?

A13. The areas to be sampled were identified; Floors, floor area to enter the Control Room, horizontal working surfaces (desk in control room), and Storage Closet Floor. The grated step surfaces Do Not Require Sampling.

Q14. Can you please clarify bucket sizes for the 88 buckets to be replaced? The specifications indicate 3.5 gallon buckets, but upon visual observation they appear to be 2.5 gallon buckets. Can you provide the replacement part number and manufacturer?

A14. The buckets are verified to be 3.5 gallon buckets. There is no part number/manufacturer on the existing buckets Q15. Likewise, for the air handling filters, can you provide replacement part numbers for the four (4) filters?

A15. Same answer as question #3.

Q16. During the pre-bid meeting, there was mention of recycling facility that accepted the lead fragments down on Neville Island. Can this facility be identified?

A16. The company name is American Steel Processing (located at 4100 Grand Ave, (Neville Island) Pittsburgh, PA) will recycle the lead/brass fragments at Exide Battery located in Eastern PA.

Q17. Can you identify the previous contractor who last serviced the range and how long ago was this service performed?

A17. AECOM was the last contractor to clean the range in support of the range upgrade in November 2016 (range was closed Nov 2016 – May 2017 for upgrade).

Q18. Page 6 asks us to wipe test the steps. These are metal grates. Wipe sampling a 12’’ square on a metal grate will not provide accurate test results. Please delete this requirement.

Q18. The areas to be sampled were identified; Floors, floor area to enter the Control Room, horizontal working surfaces (desk in control room), and Storage Closet Floor. The grated step surfaces Do Not Require Sampling.

Q19. What was the previous contract value? How many services did that include? Have the requirements changed?

A19. $38,000. Did not include 1.3.6 Ventilation System in the Statement of Work. Otherwise, the requirements are the same.

Q20. What is the name of the EPA permitted lead smelting company that the government has used in the past.

A20. Same as question 16 Q21. Since the site was covered in snow we could not verify access requirements. Is it possible to drive a truck to the back side of the range?

A21. A small pickup truck could possibly drive to the back of the range. Typically, a Kubota or something equivalent has been used in the past to access the back of the range.

Q22. Is the facility open during regular business hours M-F for pick and deliveries?

A22. Operating hours are as scheduled, typically Monday through Friday from 0730-1530, excluding Federal holidays. Access to the range at all times must be scheduled and coordinated through 911 AW Combat Arms personnel at (412) 474-8077.

Q23. Please ask CATM to use the right side of the range as much as possible to limit the amount of metal falling on the ground on the left side. This is due to broken and missing buckets A23. Request made but difficult due to the number of range operations that need to take place.

Q24. Will the government remove all equipment and supplies from the range prior to cleaning? This would include ATVs, boxes of brass, paper from the desk etc.

A24. Yes Q25. Have the lead removal standards routinely been met on previous cleanings?

A25. The range was cleaned in the past years, however, wipe tests were not conducted.

Q26. The pricing sheet lists the cleaning of wall duct. We were not able to find any wall ducting. Please clarify.

A26. See facility drawings attached in Fedbizops
