FA6712-16-R-0002 – Repair Small Arms Range - RFI Responses

Question 1: What standard or acoustic coverage is a minimum requirement?

Government Response 1: This range is located on Air Force property and this project will be funded by the Air Force, so the range needs to be designed and built to Air Force standards and does not need to meet US Marine Corps standards. Range must have a reverberation rate below 1.5 seconds at the main firing line and all points behind the firing line. Use of the word “feasible” in the Statement of Work (SOW) related to noise control will be deleted and that sentence revised. Sound-absorbing materials are to be added to the exposed portions of the back and side concrete block walls behind the firing line, and to the ceiling behind the firing line if necessary, to achieve the specified reverberation rate. Reverberation rate for all points of the range forward of the firing line are not being specified, but will be whatever results from using the materials and methods specified in the SOW for the baffles, side and center walls, and floor of the range. Actual noise levels in that area will be determined after construction and appropriate hearing protection specified.

Question 2: Is there a requirement in Clinton, PA to meet the 2012 NFPA 286 corner fire test?

Government Response 2: There is no requirement to meet the 2012 NFPA 286 corner fire test at this range.

Question 3: Could you also tell us if this is a fixed firing line range, or if the shooters walk down range?

Government Response 3: This will not be a fixed firing line range, since the shooters will walk down range on some training scenarios. Though the main firing line will be 25-meters from the target line, this range is intended to also be used for move-and-shoot courses of fire and shorter distances of fire. Movement toward the target line will be permitted once the additional baffles required to make the range “fully contained” are designed and constructed to stop direct fire at all downrange firing lines.

Question 4: SOW, Page 4, 3.a. Site Visit/Kick-off: Are subcontractor’s Project Manager and Site Superintendent required to attend the site visit/kick-off meeting or just the prime contractor’s lead personnel?

Government Response 4: The prime contractor’s Project Manager and other lead personnel are required to attend the site visit/kick-off meeting, but it is up to the prime contractor to decide which, if any, of the subcontractors and personnel will be requested to attend those and any other visits or meetings.

Question 5: SOW, Page 4, 7.d. Air Reserve Station’s truck scale. How far and where specifically from the small arms firing range is the truck scale located? What procedure is required to access the truck scale? How long does the process take to access the truck scale from arrival at the gate to leaving the base? Would the 911th AW consider using an estimate volume in lieu of a weight to complete shipping documents? The weight can be provided by the disposal/recycling facilities.

Government Response 5: Weights for solid waste can be obtained through use of the installation truck scales located near Building 320, certified weighing devices located at recycling and disposal facilities, or by using a commercial weigh station. To access the installation truck scale, the Contractor would follow the required Security Forces procedures for entering the installation. It can be estimated it will average about 1 hour to complete the process once arriving at the installation each visit. To avoid having to use the Air Reserve Station’s truck scale the Contractor may use an estimated volume in lieu of a weight to complete shipping documents, with the actual weight being provided by the disposal/recycling facilities. In that case, the shipping documents must contain the estimated volume of the hazardous waste being shipped on the signed manifest prior to shipping the hazardous waste from the firing range. The estimated shipping volumes are to be corrected to reflect actual weight by the receiving facility.

Question 6: SOW, Page 6, 3.3. Air Monitoring. Will air monitoring be required for the entire project or just during lead remediation and demolition? Will personal, work area, and/or perimeter air monitoring be required?

Government Response 6: Air monitoring will definitely be required during the lead remediation and demolition work. Per paragraph 1.2.B.8.f. of SOW, the Contractor is solely responsible for the health and safety of its workers during execution of the Contract and must follow the OSHA standards. The Contractor would determine if and to what extent air or other monitoring is required for the project to protect their workers.

Contractor is responsible for meeting OSHA regulations pertaining to their personnel.

Since no military/ Combat Arms Training and Maintenance (CATM) or other Government personnel shall be exposed to the work site for extended periods during the construction phase, no OSHA air sampling for Government employee exposure is required.

Question 7: SOW, Page 6, 3.f. and Page 7, 3.f.3. Requires a clarification. Page 6 contains a statement that all waste must be containerized in steel drums. Later on Page 7 states that other containers may be used. We are assuming a DOT approved container can be used to ship waste.

Government Response 7: Any type of container is acceptable, as long as the container is DOT and RCRA approved for the type of waste being shipped.

Question 8: SOW, Page 7, 3.f.4. Sampling and Analysis. To clarify, sampling and analysis is only needed on waste streams as needed? No wipe samples are required on work surfaces.

Government Response 8: Sampling and analysis is required to characterize all distinct waste streams as needed to properly recycle or dispose; at a minimum, testing should be done for TCLP metals (not just for lead). Some wipe samples will be required. If Clearance wipe samples are not taken by the Contractor after completion of the lead abatement and cleaning there would not be any quantitative results demonstrating that the area has been sufficiently cleaned from lead hazards. Also, it is required that site specific (shooter lanes/positions and range control) wipe samples be accomplished prior to the re-occupation of the site by government employees.

Question 9: SOW, Page 7, 3.f.6, Submittals. Do all workers require lead abatement training or only those performing remediation and demolition?

Government Response 9: Those workers involved with the lead abatement would be required to have the lead abatement training. All workers exposed to lead hazards are required to be trained for OSHA 29CFR1926.62.

Question 10: SOW, Page 9, 3.o. The document states a percentage of wall panels to assume requires disposal but not floor panels, only those “severely damaged”. Please provide a percentage to further define scope of work.

Government Response 10: . Intent is to remove all rubber panels from the floor of that area and not reinstall any rubber panels on that floor. Some of the rubber tile from the floor will be installed on the walls between the firing lane and the bullet trap as detailed in paragraphs 1.2.B.8.o, w and y of the SOW. All rubber floor tile not installed on walls shall be disposed of by the Contractor. Since SOW paragraph 1.2.B.8.y requires rubber panels on those walls to be reinstalled from floor level to a height even with the top of the new overhead baffles, which will be to a greater height than panels are currently installed, the total number of panels from walls and floor to be reinstalled on those walls will be greater than the total number of panels removed from the walls. The actual number of floor panels to be reinstalled on the walls and to be disposed of will depend on Contractor's final design.

Question 11: Site Walk Statement. It was stated that lead abatement would include the removal of lead slugs from the baffle media. How is this to be quantified for level of effort and pricing?

Government Response 11: Per paragraph 1.1 of the SOW the existing baffles are constructed of two sheets of 3/8” thick steel plates, framed with wood 2x4s at 24” on center that are bolted to the steel plate to act as a substrate for the 3/4" thick plywood sheets that are covered with 1-1/2” thick eggcrate profiled acoustical foam. It is assumed that much of the lead bullets will be found in the void created by the 2X4s between the plywood and the steel plate. There will be dust and some lead fragments in the plywood and 2x4s. None of the above can be quantified, but the amount of lead in the voids and in the wood of each row of baffles will increase as one moves toward the target line/bullet trap.

Question 12: SOW, Page 3, 1.2.A Bullet Trap. What work and remediation is to be done related to the bullet trap?

Government Response 12: Only work to be done on the bullet trap is to replace the acoustic panels laying on top of the bullet trap outside under the bullet trap metal roof and to replace the gutters and downspouts serving that bullet trap roof. As detailed in paragraph 1.2.B.8.n of the SOW, Contractor will replace or modify the existing set of baffles and/or steel truss support system located immediately at the bullet. Under this contract the Contractor is responsible for lead remediation from the entire area from the floor drainage trough at the front edge of the bullet trap to the back wall of the firing range behind the firing line, from floor and bottom of tough to ceiling and top of baffle support structures. Contractor is not responsible for lead remediation in the bullet trap or its lead collection system.

Question 13: Since this installation is not on the 911th site, how will security issues be handled? Will deliveries, short term workers, etc. be required to obtain a pass from the 911th facility prior to coming to the Small Arms Range?

Government Response 13: This is not a facility within the installation, therefore Security Forces would not have capabilities to ensure all contractors/delivery personnel are vetted. Security Forces does not see reason in vetting individuals who pose no threat to our priority resources or the installation.

Question 14: . There is a requirement in the technical package for a schedule. There is also a statement in the RFP "DO NOT SUBMIT A GANTT CHART". Since a bar chart schedule is a Gantt chart, what are we to actually submit?

Government Response 14: A Gantt chart is a more detailed bar chart format schedule than required or desired for the proposal. A less complex schedule, which may be a bar chart, which covers all major design and construction elements, is considered sufficient. Offerors may use AF Form 3064 Contract Progress Schedule, a copy of which is attached with instructions, or a simpler bar chart format schedule than a detailed Gantt chart, for the schedule required with the proposal.

Question 15: In one area of the scope of work (Page 9, O) indicates that we are to remove 15% of the existing 2'x2' acoustic rubber wall panels. In another section (Page 11, W) states "remove all 2" thick ribbed acoustic wall panels". Is this referring to the same item? If so what is the intention?

Government Response 15: . Intent is to remove all rubber acoustic wall panels from the walls between the firing line and the bullet trap, but it is anticipated that only about 15% of those wall panels will need to be disposed of, while the remaining 85% of those wall panels will need to be reinstalled, along with additional non-acoustic rubber panels to be removed from the floor, after appropriate surface preparation, all as detailed in paragraphs 1.2.B.8.o, w and y of the Statement of Work (SOW). Intent is to also remove all rubber panels from the floor of that area and not reinstall any rubber panels on that floor, but some of the floor panels will be reinstalled on the walls of that area and the Contractor is to dispose of the remainder of the floor panels. Since SOW paragraph 1.2.B.8.y requires rubber panels on those walls to be reinstalled from floor level to a height even with the top of the new overhead baffles, which will be to a greater height than panels are currently installed, the total number of panels from walls and floor to be reinstalled on those walls will be greater than the total number of panels removed from the walls. The actual number of floor panels to be reinstalled on the walls and to be disposed of will depend on Contractor's final design. No new acoustic wall panels or other acoustic materials are intended for the walls between the firing line and the bullet trap. Only area specified to receive new acoustic panels is the area behind the firing line as detailed in SOW paragraph 1.2.B.8.z as revised by Amendment 0002. New ballistic panels are also required on all the baffles, but they need not be acoustic panels.

Question 16: Please provide information on 'Witness Screens" noted in scope of work (Page 13, AM).

Government Response 16: Please see paragraph 8.4.2 of ETL 11-18, Attachment 3 of the SOW, which details the use and construction of the witness screens.

Question: 17. 1.1 Background “feasible” Clarify the requirement to upgrade the ventilation and noise control “where feasible”. Should this be based on cost feasibility or on practical feasibility.

Government Response: 17. See Amendment 0002 that revised the wording of paragraph 1.1 which included deleting the words "where feasible". Amendment clarifies extent of noise control required. Ventilation to be reconditioned and upgraded as specified elsewhere in Statement of Work (SOW) as written and as discussed in responses to other below RFI items.

Question 18: 1.2 Summary of Work Rubber wall panels This paragraph includes “removing and refastening all existing rubber panels”. Is it the intent to reuse all of the wall panels or replace them with acoustical materials.?

Government Response 18: Intent is to remove all rubber acoustic wall panels from the walls between the firing line and the bullet trap and reinstall on those walls some, approximately 85%, of those same rubber acoustic panels that are reusable, along with additional non-acoustic rubber panels to be removed from the floor, after appropriate surface preparation as detailed in paragraphs 1.2.B.8.o, w and y of the SOW. No new acoustic wall panels or other acoustic materials are intended for the walls between the firing line and the bullet trap. Only area to receive new acoustic panels is the area behind the firing line. New ballistic panels are also required on all the baffles, but they need not be acoustic panels.

Question 19: B Design, Paragraph o Rubber Wall panels States to remove “approximately 15%” of the rubber wall panels that have been damaged. Scope of Work states to “remove all existing rubber wall panels”. Please clarify.

Government Response 19: Related to above response on item 2, all rubber wall panels are to be removed, but it is anticipated that only about 15% of those panels will need to be disposed of, while the remaining 85% of those panels will need to be reinstalled on the walls, along with some rubber panels from the floor that will need to be installed on the walls. The Government will assist in determining which 15% of existing wall panels are not reusable if Contractor considers more than 15% are not reusable.

Question 20: B Design, Paragraph o New Floor Slab Adding the additional 3” slab on the existing concrete will create a “step”. Is the step acceptable or will there need to be a ramp for the level transition?

Government Response 20: The 3" slab is to go from the firing line to the bullet trap.

Intent is to remove all rubber panels from the floor of that area and not reinstall any rubber panels on that floor after the 3" slab is placed. Once all the rubber panels are removed from the floor, the 3" slab should not create a step, but should be flush with the top of the wood frame on the floor at the firing line.

Question 21: B Design, Paragraph y Acoustic Panels Please verify that it is the intent that the Dura-panels will be replaced from the firing line towards the bullet trap and not from the bullet trap towards the firing line.

Government Response 21: It is the intent that the reusable existing acoustic rubber Dura-panels will be reinstall starting from the firing line towards the bullet trap as detailed paragraph 1.2.B.8.y of the SOW. Per that paragraph, when the available quantity of reusable acoustic panels is exhausted, install useable non-acoustic panels removed from the floor to finish covering the remainder of the walls to the bullet trap.

We are more concerned with acoustics closer to the firing line than down range toward the bullet trap.

Question 22: SOW Attachment #3 7.2.8" Ventilation Given this is a project is the remodel of an existing range and the SOW does not specifically callout the replacement and redesign of the Ventilation – IS the government requesting all components of the existing ventilation system to studied and re-designed? Specifically, what is our requirements specific to this range related to ventilation, can you clarify.

Government Response 22: This is a repair project and not a new construction project, so not all criteria in the SOW Attachment #3, ETL 11-18, needs to be met, including that related to the ventilation system. Past testing has confirmed that the requirements of paragraph 7.2.8.1 of the ETL are presently being met in regards to air flow and noise from the ventilation system. Intent under this project is not to improve or replace existing ventilation system, other than installing electronic speed controls or replacing fan motors on the supply fans per paragraph 1.2.B.8.ak of the SOW to make each supply fan variable speed, but rather to ensure the existing supply and exhaust fans are operating optimally by reconditioning them.

Question 23: SOW Attachment #3 8.3" Construction Inspection Is a Balancing Report required in accordance with 8.3.1 and if so please clarify RFI 6

Government Response 23: A Balancing Report is required per the ETL, but only to the extent stated in paragraph 1.2.B.8.al of the SOW, i.e., a full testing and balancing report for all supply and exhaust equipment that was reconditioned. Testing and balancing needs to confirm reconditioned supply and exhaust equipment is operating optimally and fully meets the requirements of paragraph 7.2.8.1 of the ETL when supply fans are running at maximum speed allowed by the installed controls in regards to air flow and noise from the ventilation system. Balancing report shall also document air flow and noise levels at the various settings of the supply fan controls.

Question 24: SOW Attachment #3 8.3" 8.3.2 Is the Contractor required to provide a hazardous Noise Survey?

Government Response 24: Contractor is to provide a noise survey of the enclosed area comprised of the main firing line and all points behind the firing line. One objective of the constructed repairs, as stated in Amendment 0002, is to achieve a reverberation rate below 1.5 seconds at the main firing line and all points behind the firing line.

Interior noise modeling, accomplished by the contractor, of the proposed design for that enclosed area should determine the extent of acoustic material required to meet that objective as discussed in Amendment 0002. A noise survey of that enclosed area after constructed repairs are completed is needed to confirm that above objective was met, as well as to determine the noise levels of the ventilation systems once reconditioned and modified.

Question 25: SOW Attachment #3 8.4" Test Fire Confirm 8.4.1 Applies

Government Response 25: ETL 11-18, paragraph 8.4.1 does not apply, since this is not a "non-contained range", but paragraph 8.4.2 does apply since this will be a "fully contained" range.

Question 26: SOW Attachment #3 8.5" Trial Operations Is the Contractor required to provide weapons and ammunition for the Trial?

Government Response 26: As stated in paragraph 1.2.B.8.am of the SOW, Contractor shall provide witness screens and be present during test-firing, but Government Combat Arms (CA) personnel will do the firing and provide the weapons and ammunition required for the test. Government CA personnel will conduct controlled test-firing using ball ammunition, vice tracer ammunition, since tracer ammunition is not to be used at this range.

Question 27: Acoustical Side walls of Range Subcontractor is providing the replacement acoustical material specified in the SOW. This will leave a portion of the range with the old rubber acoustics. Does this old rubber meet the current ETL requirements for the range as installed or do we need to provide layers of plywood over the old rubber to meet the ETL?

Government Response 27: Please see response to items 2 and 3 above. Even if the existing rubber panels once reinstalled do not fully meet the current ETL requirements related to noise for the area between the firing line and the bullet trap, they are consider adequate for this repair project that is not required to fully meet the ETL. Contractor is not responsible for resultant noise level in the area between the firing line and the bullet trap if existing rubber panels are reinstalled as specified in the SOW. As stated above, no new acoustic wall panels or other acoustic materials are intended for the walls between the firing line and the bullet trap. Only area to receive new acoustic panels is the area behind the firing line. New ballistic panels are also required on all the baffles, but they need not be acoustic panels. The only ballistic panels presently approved for use on Air Force ranges baffle assemblies are the minimum 2” thick Range Systems Dura-Panels and the Troy Acoustics Troy System Panels.

Question 28a: SOW Attachment #3 7.2.8" Air Flow The ETL 7.2.8 list specific requirements for Airflow- Air Distribution, however the requirement is for “fully contained ranges”. Will we be required to design to these standards?

Government Response 28a: Please see response to items 6 and 7 above.

Contractor will only be responsible to meet criteria in ETL 7.2.8.1 within 7.2.8.

Question 28b: Paragraph “al” of the statement of work requires various test requirements to be made for the range ventilation system. However, paragraph ‘ak’ states that the 11 existing supply and exhaust fans are only to be reconditioned, the only new component will be the variable speed electric motors. I am unsure how we can guarantee airflow and noise requirements for what will essentially be an existing condition?

Government Response 28b: Please see response to items 6 and 7 above. Existing equipment currently meets criteria, so there should not be a problem for reconditioned equipment meeting criteria.

Question 29: Is the contractor alone responsible for the repair to the existing road conditions, and all maintenance of the road during the Construction Project? Will any repairs and maintenance be done on the road prior to the construction phase of the project beginning?

Government Response 29: FAR Clause 52.236-9 -- Protection of Existing Vegetation, Structures, Equipment, Utilities, and Improvements is applicable to the area within the fencing around the firing range facility (site of work). With that said, the dirt access road leading to the facility is the property of the U.S. Marines. In the event of any change in condition to the road, beyond normal wear and tear will be referred to the U.S. Marines for disposition.

Question 30: Please give further detail on the gutter system required for the back side of the ballistic baffle panels. Please forward details, or examples. A conventional gutter system would protrude below the Baffle panels and therefore be hit by live fire rounds.

This requirement may not be ETL compliant.

Government Response 30: Gutter/channel system on back of baffles to be designed by Contractor. Government envisions some type of metal channel, much smaller than conventional gutter, fastened low on the back side of each row of baffles with a slight slope each direction from the center of row to direct water toward the two walls adjacent to that row of baffles. Gutters are not to protrude below the bottom of baffles, so they will not be able to be hit by direct fire.

Question 31: Can you supply any Mfg. data on the supply fan motors other that the motor schedule in the as builts? Motor casings have been painted over?

Government Response 31: The installed supply fans are Wind Master fans, housing model # DC30H, motor model 3KJ56T17T3498BP, 3/4 HP / 3 PH / 60 HZ, manufactured by Acme Manufacturing Corp, Muskogee, OK. Corp.

Question 32: Lead Worker Certification Requirements, is this just for the Abatement Team, and once the range is clear all other construction trades do not have to be certified?

Government Response 32: Those workers involved with the lead abatement would be required to have the lead abatement training and certification. All workers exposed to lead hazards, such as demolition that follows the remediation, are required to be trained for OSHA 29CFR1926.62.

Question 33: There is an option for Red lighting in the ETL (7.2.11.3. Lighting) Does the Government want any Red Lighting?

Government Response 33: This is a repair project and not a new construction project, so not all criteria in the SOW Attachment #3, ETL 11-18, needs to be met, including that related to the Red Lighting. The Government does not want any Red Lighting under this project.

Question 34: In reference to Amendment 2, #3. Is 3rd party testing required to certify the requirement for the reverberation rate to be below 1.5 seconds has been met?

Government Response 34: 3rd party testing is not required to certify that the requirement for the reverberation rate has been met, but the testing may be accomplished by a qualified member of the Contractor’s design team with significant experience in conducting such testing, in using the appropriate testing equipment, and in providing report of testing results.

Question 35: In reference to Amendment 2, with the required reverberation rate of 1.5 seconds, are the Dura panels still to be reused along the entire sidewalls? The range may not meet the ETL standard or the required 1.5 second reverberation rate.

Government Response 35: Per Amendment 2, “Reverberation rate for all points of the range forward of the firing line are not being specified, but will be whatever results from using the materials and methods specified in the SOW for the baffles, side and center walls, and floor of that area of the range.” Even if the existing rubber panels once reinstalled do not fully meet the current ETL requirements related to noise for the area between the firing line and the bullet trap, they are consider adequate for this repair project that is not required to fully meet the ETL. The Contractor is not responsible for resultant noise level in the area between the firing line and the bullet trap if existing rubber panels are reinstalled as specified in the SOW. No new acoustic wall panels or other acoustic materials are intended for the walls between the firing line and the bullet trap.
