Repair Small Arms Range, Bldg 701 Projects DZAQ 15-0001A/B

PITTSBURGH IAP ARS, PA

18 November 2015

1.1 BACKGROUND

This project focuses on Small Arms Range, Bldg 701 at the Clinton Training Area in Beaver County in the vicinity of the Pittsburgh Air Reserve Station (PARS) shown on the attached Project Location Maps (see Attachments 1 and 2). The range was built in 1997 as a “partially contained” range that has a covered firing line, side containment, 9 rows of overhead baffles, including one row that serves as the canopy baffle, that each spans the full 112’ width of the range, and a bullet trap/backstop. Each overhead baffle is 4’ wide and 8’ long and is 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. Individual baffles are butted together to form each set of the 9 rows of baffles that span the width of the range. Direct fire at the firing line is totally contained by the side containment, overhead baffles, and bullet trap, but direct fire forward of the firing line and ricochets are not totally contained, though reduced by the baffles and side containment. The foremost purpose of this project is to upgrade the range to a “fully contained” range that will totally contain both all direct fire and ricochets within the limits of the range by adding additional overhead baffles and supporting structures, in accordance with Air Force Engineering Technical Letter (ETL) 11-18: Small Arms Range Design and Construction (see Attachment 3). That ETL provides the minimum design criteria necessary for achieving a safe range design and shall be followed for this project in all aspects related to the baffles, unless modified by details of this Statement of Work (SOW). Since the range is being upgraded, it will be brought to that ETL’s standards for not only the baffles and other ballistic safety structures, but also for ventilation and noise control where feasible. It is the policy of the Air Force to use innovative and sustainable approaches to environmental management and technology to accomplish its mission. Sustainable projects do not deplete resources, cause environmental degradation, or impact to human health and may reduce the burden of compliance for the Air Force. Mission requirements are met while also balancing cost and environmental responsibility.

The Contractor shall incorporate pollution prevention and sustainability initiatives into all aspects of this contract.

Lighting shall meet the requirements of ETL 11-18 paragraph 7.2.11.3. New lighting shall be LED and shall be on a separate circuit with new controls mounted in the Control Room.

ah. Remove and replace bullet trap acoustical quilts with comparable material and position and fasten new quilts or panels as appropriate without compromising integrity of the bullet trap.

ai. Remove and reinstall existing gutter at rear of the facility. When reinstalled it shall slope from center to both ends. Replace existing downspout at east end and construct new downspout at west end with extension under concrete sidewalk to drainage ditch north of the sidewalk. Provide splash block at the end of each downspout.

aj. Install four 11.75” OD round galvanized steel or PVC ducts with caps through wall for connection of trailer mounted portable heater flexible hoses (see Attachment 10 for approximate locations). Top of ducts shall be no higher than the top of the second course of CMU blocks.

ak. Recondition 11 existing supply fans and 11 existing exhaust fans by replacing the belts and cleaning the fan blades of each and by providing new supply air discharge grilles to avoid high velocity jets and initiate a laminar flow pattern. Install electronic speed controls or replace supply fan motors to make each variable speed, since full speed fan in winter makes it too cold at the firing line. Allow the fan speeds to run at maximum speed within noise limits discussed below. The supply fans are located in the rear wall behind the firing line and deliver 8,400 CFM each of supply air to push unconditioned outdoor air through the firing line, across the shooters, and out to the exhaust fans. The supply fans are standard wall propeller type equipped with an outdoor air louver on the fan upstream side and a supply air grille located flush with the interior surface of the wall on the fan discharge side. The fans are belt driven and are served by ¾ HP, 480 volt, 3 phase, 60 hertz motors. The fan located in the center of the building has a ducted discharge directing the supply air under the Observation Platform. This fan is equipped with a 1-1/2 HP 480 volt, 3 phase, 60 hertz motor. The fan motors are controlled by combination across the line motor starters with integral disconnects. The exhaust fans are located on the sloped roof above the firing line. These fans exhaust 76,230 CFM to atmosphere.

These fans are what are commonly called “Mushroom” fans. The roof curbs are equipped with gravity back draft dampers that close when the fan stops. The fans are belt driven and each is

Projects DZAQ 15‐0001A/B 13 18 November 2015 served by a 1 HP, 480 volt, 3 phase, 60 hertz motor. The fan motors are also controlled by combination across the line starters and are interlocked to run when the supply fans run.

al. Range ventilation performance will need to be validated prior to final inspection to ensure that proper ventilation is provided within the range. At the firing line, the air velocity must be a minimum of 23 meters per minute (mpm) (75 feet per minute [fpm]), ±4.6 mpm (15 fpm). Airflow should be evenly distributed across the firing line ±4.6 mpm (15 fpm). Noise from the ventilation system will not exceed 85 decibels (dBA) behind the firing line. Test and report speed and air flow delivery rate after fan modification and installation of additional acoustic baffles are completed. Adjust fans as necessary to achieve a minimum required air flow and speed across the firing line, even distribution, and noise within limits. The Contractor shall provide, prior to final inspection, a full testing and balancing report for all supply and exhaust equipment that was repaired.

am. After all repairs and construction have been completed, and before conducting training and qualification operations, Government Combat Arms (CA) personnel will conduct controlled test-firing using ball ammunition with witness screens as detailed in the ETL 11-18 as appropriate. Contractor shall provide witness screens and be present during test-firing, but Government CA personnel will do the firing and provide the weapons and ammunition required for the test. Any additional work determined to be required from the results of the test-firing, that are considered to be of no fault of the Contractor, may be accomplished under an in-scope modification to the contract if funds are available and work via a modification is considered in the Government’s best interest. Any rework or additional work deemed to be the responsibility of the Contractor shall be accomplished at no additional expense to the Government.

an. The Contractor will incorporate, to the realistic extent possible, guidelines and recommendations included in the revised "Federal Green Construction Guide for Specifiers" on the Whole Building Design Guide. http://fedgreenspecs.wbdg.org.
