6. QUESTION: Per discussions with the bullet trap and baffle system companies, the lead time for fabrication of the bullet trap is approximately 12 weeks from submittal approval and an additional five weeks for installation for the bullet trap and baffle system. Based on that timeline, this will only leave two weeks for project testing, inspections, punch list correction, final cleanup and restoration. Please consider allowing 210 calendar days for construction or providing NTP once the bullet trap submittal is approved in order to have time to provide submittals, government review, fabrication, delivery, and installation of the bullet trap system.

ANSWER: CE has no objection (DS). 3/28/2017

ANSWER: Remove stump if it interferes with footing, piles or passageway (DS). 3/27/2017

12. QUESTION: Will the contractor be allowed to use some of the parking lot for our temporary trailer and staging area?

ANSWER: Due to range closure a limited area of the parking area can be used by the contractor for staging and a temporary trailer. However the office building will still be occupied by Air force personnel and the areas used will have to segregated form the parking for the staff, All areas must be coordinated with LGC/CE also any disturb areas must be placed back or made whole as was previous found prior to disturbance. Contactor shall also be allowed to use “Dead Runway” area for a possible lay down area for large materials

27. QUESTION: The slab is very uneven across the range from one side of the current bullet trap to the other. Since a new slab is being poured under the new bullet traps, the traps themselves can be made level. However, the mouth of the bullet trap will extend out so far that it will reach the unlevel part of the slab. The trench cut into the concrete to hide the edge of the mouth steel plate can cover some of this, but there may be instances where the bottom plate of the mouth will not be flush with the slab due to existing concrete grades. Is this a concern?

ANSWER: Yes refer to detail 5/A502 for trench requirements for leading edge of ramp.

(MSH) 3/24/2017

28. QUESTION: What certifications are required for the steel erector?

ANSWER: Refer to specifications 13 34 19 para 1.6.4 page 11 (DS). 3/23/2017

29. QUESTION: The ETL shows “Partially contained range: This range has a covered firing line, side containment, overhead baffles, and a bullet backstop. Direct fire is totally contained by the firing line canopy, side containment, baffles, and bullet trap (no “blue sky” observed from firing positions).” An assumption is made that this is a single firing line range and that no current or future training on this range (as designed) involves moving forward of the static single firing line.

Is that a correct assumption?

ANSWER: Yes (DS). 03/23/2017

30. QUESTION: The ETL shows “Ambient noise levels at the firing line shall not exceed 85 dBA.

Short-duration noise such as gunfire will exceed the 85 dBA level and may be as high as 160 dBA. Reflective surfaces in a range will reverberate noise during firing, extending the decay rate of the noise. Long decay rates (>1 second) will require the engineer to treat the noise not only as impulse (peak pressure considerations) but also as continuous noise. Therefore, sound-absorbing materials should be used to reduce the reverberation rate to below 1.5 seconds.” Is it the government’s intent to meet this ETL requirement on this project even if it is a single firing line only?

ANSWER: No (DS). 03/23/2017

31. QUESTION: Is the current electrical service to the site adequate for the electrical being added?

ANSWER: Yes, no change to the transformers are required per GA power determination

03.14/2017 however the plans show detail and notes on sheet ES101 that require coordination with GA power for connection to transformer. (MSH) 03/24/2017

32. QUESTION: Will all existing bullet trap debris be disposed of off site by the contractor, or does the base have to keep any hazardous materials on base?

ANSWER: By contractor refer to 01560 para 3.7 and 3.7.4.2.1 (DS). 03/23/2017

33. QUESTION: Section 1.4.1 – Please Clarify - Manufacturers Qualifications – needs more definition.

ANSWER: Provide which specification? If 11 97 50 is being referenced per 1.4.1 five (5) years of experience is required for manufactures qualifications is required also refer to 1.4.2 of specification 11 97 50 (MSH). 03 24/2017

34. QUESTION: We need a soil report so that we can look at the borings. We are not allowed our usual overage clause when bidding this job and do not want to guess

ANSWER: Refer to Question #8 will provide (DS) 3/23/2017

35. QUESTION: Is there a safety and/or quality control personal required besides the superintendent? If so, can either one be the superintendent as well?

ANSWER: Refer FAR contract clause: 52.236.6 and to Specifications Section 01010 General requirements 3.16.6 that requires a Quality control plan to be submitted. Normally a site superintendent/QC/safety are required on most government construction contracts. However ensure compliance with the stated references. Nothing prohibits superintendent as being site safety as long as they have the required training. (MSH) /3/22/2017

36. QUESTION: What planting is required for this project? Is it just the areas that have been disturbed during the construction period?

ANSWER: Disturbed or damaged area. See specs & drawings. (DS) 03/23/2017

37. QUESTION: Section 11-97-50 Bullet Containment System. 1.2 Equipment - This section states that no Armor Piercing rounds are to be used, yet it appears to allow for the M855A1 round.

Please clarify. If the M855A1 is to be used, how many rounds will be fired per year?

ANSWER: Due to the SDZ limitations of this range, only frangible ammunition will be used.

However bullet containment system must still meet the required design as stated.

38. QUESTION: Section 11-97-50 Bullet Containment System. 1.7 Warranty - A 2-year warranty is required for this project. To be accurate in providing proposals, it is important that we understand the number of rounds anticipated to be fired on this range over a specific period of time. Also, if that number can be specific to any 5.56mm and 7.62mm usage as well.

ANSWER: Approx. 100,000 rounds per year of frangible ammunition. Combination of 5.56 and 9mm. (DS) 3/28/2017

39. Can the government identify and/or specify “waivers” that are in place for this project that would exclude certain ETL acoustic coverage for this project? Specifically related to ETL 11-18. The specifications nor the drawings show ETL acoustic coverage on the existing concrete walls, above the new ballistic ceiling system, or other locations that the ETL typically requires for a new system. Full acoustic coverage per the ETL would cost an extreme amount but these items are not shown in the drawings or specifications for this project.

ANSWER: Ballistic tile is shown on horizontal baffles and ceiling above shooter (DS).
