Shooting Facility Design 2

[irfansiddiqui]

Dear All,

I got a project of HVAC designing of a shooting facility, i never designed it before,
If any one can help me finding guidelines for HVAC designing ????

good stuff, check it out and come back with questions.

knowledge is power

check the navy manual

Not really sure what the Navy needs INDOOR ranges for (enemy ship attacks inside, entering enemy ship and shooting inside?), but they have good guidelines.

when we started up our system we had some lead exposure issues of custodians till we fixed that. So yes it is important to design right.

I'm not sure where cross-wind would be a problem indoors assuming you provide air from behind the shooter towards the bullet trap.

I have an idea, why don't we start doing Industrial Rngineering?

Hire an Engineer who knows what he is doing, you are likely over your head.

willard3: not sure if you mean this, but the thread-starter likley is an experienced engineer, just not in shooting ranges.
and who shoudl he hire, most consultants that claim to have experience, don't have squat. unfortuantely it is common to embelish experience whne applying for a project.
Most consutlants also let the interns and technicians design most, and a ighly decorated principal stamps the plans.

I do a lot of my own design, but also supervise hired consultants. Most of them operate the way I described.
so the thread starter is better off using his own brain and ask on this forum.

HerrKaleun,
Ever hear of the US Marines? They are part of the Navy and do a lot of shooting.

Trashcanman: good point, I didn't consider that. I think traditionally marines were transported by ship to overesaes and therefore belong to the Navy... today they likely should belong to the Airforce since most get transported by plane but then we also have aircraft carriers with planes... mmmh. how is that Navy?

 

[TheBlacksmith]

Even the biggest planes have range limits. A moving 4 1/2 acre airfield that can remain in international waters is a valuable asset, as is the ability to carry the 30 days worth of beans and bullets a Marine force needs upon landing. Also, many sailors do need to qualify in small arms, regardless of the weather. I ran an indoor Navy range for a time.

I would contact police departments, armed forces, gun manufacturers, and private indoor shooting ranges for their inputs.

 

[chicopee]

The Navy has also military police, not that they did any good lately in Washington DC.

to who this facility belong? Is it a military training facility or a civilian sport facility?
For a civilian sport facility then You do not have to go too complicate, just contact the city where the project is located, ask them about their requirement and the code they apply, then go ahead with your design.
if they don't have a specific standard, then just design it as a regular project and do not bother with navy or air force or NASA, it is just an HVAC

 

[TheBlacksmith]

I wasn't very helpful before, the main points are airflow downrange; even if lead fres bullets are used, most common primers contain and therefore release a minute quantity of lead, do not want that blowing back in the shooter's faces. Second would be adequate filtration, probably HEPA these days.

One thing to consider is that you should make sure your exhaust filtration s sized properly. Filters should not have more than 500 fpm (they will collapse when overloaded!).
You also should monitor dP via BAS on each filter stage so you can determine proper replacement times. Filter replacement is very expensive, but contamination will cost even more.
you should talk to the filter-replacement company when designing.

this is all hazardous filtration and will cost you several thousands of 4 each year for smaller facilities.
