Is there a charge for that that can go into the > "replacement fund"? Here's what I've been told by the district admin: this company charges $60/hr to operate the facility, using all our equipment. The hourly charge is charged to the renter, not to the school or district. I would suppose if a 'crew' were needed, that too would get charged to the user. From what I am told, they will NOT be using students, but "professionals." (Their quotes.) Yes, the outside company gets to use whatever we have, so I am told. Historically, the school/district has had a poor record of getting outside renters to pay for damage - apathy towards the issue is more precise. Out of sight = out of mind. After all, the only complainer about the paint on the drapes, the duct tape on the grand drape and walls, the broken lighting fixtures and furniture - well, it's only the Theatre Arts Program complaining.... burning "Class of 04" in the stadium grass is a much bigger issue that apparently consumes and reflects on the entire school. ;) One possible silver lining: there will be very few outside rentals, as there will be no one to market it, and as I have been told many times by the district, "We don't want to be landlords." I just think it's arrogance on their part - they go to the voters, ask for $10 million (for the complex - $75 mil, district-wide), then say, "no one can use this space but us." In the past, the greatest damage and such was actually from inside events: concerts, NHS meetings, class meetings, etc. Equipment is being set up by teachers who have no knowledge in this area, doors are left unlocked/propped open, stage lights are left burning 24 or more hours, sound equip walks away, drapes get torn (mishandled) - and this was before we had an orch pit or fly system!

Copper plumbing is so fast and easy, there's hardly any comparison to steel pipe. Also, seems to the last time I looked, a 10' length of copper was cheaper than a 10' length of comparable iron pipe, and the fittings a way cheaper. Most of the production crews I've worked on have a hose running from the compressor to a manifold... a steel box, custom made, usually about the size of a shoebox. They usually have one input and 8-10 outputs. No drop in pressure. Coordinators usually provide really butch 1/2" air hoses. I bring my own 3/8" Senco hose because swinging an M2 around is hard enough without a honkin' rigid airhose sticking out the ass end. PVC is a no-no for air systems or tanks. From what I was told, PVC will expand under pressure but not return to its original size when depressurized. The next time it expands a little more... and so an until it explodes. I've seen it explode at around only 8 lbs. of pressure. Scary.

Subject: Re: Air flow Date: Wed, 21 Jun 2006 12:36:05 -0700 Oh yes I have, but throw in the pipe treading machine cut it thread it ream it flip it around do the same thing done put pipe dope on spin it by hand till in what eve fitting give it full turn with a pipe wrench done faster than it took me to type this paragraph. No worry about burning the place up or anything other things happen with fire around in a building. But if had to hand thread all the pipe I would go with copper as that's going to add a lot time and a good upper body work out. So right about the hose size, unless you running a 1" impact, jackhammer or big sand blaster no need for anything larger than 3/8" that I will ever deal with these days. After the first time the batch man would rip the 2" galvanized water mains out of the ground by water hammering. I would make a water hammering prevention device out of 8", 10 foot long sch 80 PVC with sch 40 adaptors with a couple of valves on it to drain to it ever so often. The commercially made ones available would explode in less than a day with the work load they had on them. But still wouldn't do a compress air system with PVC. One other thing if is a metal piping system it need to be boned to the electrical ground in the building, I got busted on new industrial building I built by the a city inspector once. ----- Original Message ----- From: "Paul Guncheon" > > > Sounds like somebody who has not worked with copper.

In-Reply-To: Ja, that's why we're looking at doing it all with some big, beefy hose rather than rigid pipe. I can get a 250' spool of 1/2" hose from Grainger for less than $200 and use about half the fittings I'd need if I were putting in any kind of pipe. I figure I'll run lines out along the roof trusses and drop it down at each of the 6 center posts to a regulator on each post (with a water drain at each one.) From there the carpenters, painters, etc. can run smaller hoses out to their work areas. Mostly we'll be using stapleguns, which don't take a whole lot of volume at a high rate. I just wanted to make sure that 1/2" would be big enough for those periods of peak airflow where perhaps a sprayer and an air-ratchet are also being used. Fred Loren Schreiber wrote: > Wow!

Another possible advantage of metal over plastic is that I would think plastic won't last as long. Even indoors, plastic might degrade faster and is susceptible to more chemicals than metal.

Where the stage area is grater than 1000 sq ft, ventilation - for smoke exhaust - is required by both the International Building Code and the Life Safety Code. That criteria was established at the same time the 50 ft rule for fire safety curtains was introduced. Venting may be either by gravity (hatches or Bilco's commonly) or by a mechanical system (one tough, big range hood.) My practice in developing a design for a studio theatres, black box, etc., is to prepare seating layouts. I outline the seating area and required aisle area and subtract that from the room area. Quite often it is less than 100o sq ft and vents are not required. Bill C.

Tough to attend everything at a 3 day conference and attend 5 shows in 6 nights - plus internet seems to never be free in London as it often is in the US. As Bill S. noted, it was a wonderful conference with over 300 folk from 31 countries. About the only place I know where you can here an architect from India discuss building spaces for traditional Indian performances and then here about the machinery at KA. Fascinating. I thought I'd like to report - over several posts - on some of the highlights. First, while primarily architects, engineers, and theatre consultants, there was a significant designer and technician group. That group over several presentations made some important points on design of theatre buildings that likely most of you all know and understand intuitively but I think they bear repeating. First, design the building so that it is easy to hang stuff anywhere - any place in the theatre or house and probably lobbies and other backstage spaces. Second, don't make things in concrete and don't weld anything. Similar message but at sometime in the life of the building it is likely that much of it will be in the way and there will be a desire to move it. While the complete prohibition on concrete and welding is extreme, the lesson is clear. Special mention for seating - don't use the typical theatre seat insert with a threaded stud anchored in the floor. Now to battle with the seat manufacturers. (I wish it were so easy as some folk think that one simply tells the builder what to do and it gets done that way.) Third, and more designer influenced, the upstage wall of a stage should be brick. Ponder that. I saw 5 shows and excluding 2 at Shakespeare's Globe, 2 of the other three used the brick wall as part of set design (I assume brick - could have been plastic brick applied to some other wall): Piccadilly and Cottlesloe. This will be hard to get very often but I think they are right. Fourth, from a wardrobe person, lots of plugs. There are so many things that plug in that I'm convinced continuous wiremold everywhere might not be excessive. Next up: The closing all-conference debate on flexible spaces and found spaces versus what is being built today. Bill C.

Adobe and staw bales? Recycled tires and diapers? Well, I tend to think framed walls with plaster and drywall and even block walls are easier to modify and restore than a monolithic reinforced concrete building. Broadway and touring theatres of old seem to mostly have wood framed wood floors which were regularly cut up and restored. Now we have a slab a few inches under most stage floors. And all those riggers who want to weld the blocks to the structure - how I hate that. Based on my observations, I think it's probably a good principal to guide the planning.

The general consensus was that plastic is bad for air lines, as a failure may result in a rather nasty explosion of stiff shards of sharp plastic flying everywhere....we're going to use copper pipe for shop air... ........>> Carla, This has been mentioned on this list before also. Plastic can be very good for air lines depending on What Type of plastic. PVC is no longer code for compressed air unless it is encapsulated. ABS plastic (solid core) DOES meet code. The reason is that PVC is brittle and when it fractures, it produces shards which when released under pressure is called shrapnel. ABS on the other hand, splits when it fails under pressure and simply lets the air out. PVC was used for many years in many places without trouble but when it does fail, it does so spectacularly. The main reasons for PVC failure were exposure to sub zero temperatures and/or impact. As few scene shops have temps below 0 F, that particular problem was not significant to us as theatre technicians.. Plastic has some advantages, it is very easy to work with, light weight, rated for pressures higher (260psi to 300psi and higher) than most shop air systems at 125 to 150 psi., It never rusts or corrodes. Very inexpensive. It is soft and subject to impact damage at fairly low impact forces. Iron pipe, black or galvanized, requires threaders, cutters and a reasonable degree of skill in plumbing. Lots of expensive Union fittings are required if you want to make a system that can easily be serviced without dismantling large portions of it to fix one pipe or joint. Black pipe will of course eventually corrode, rust and clog from the moisture that collects in the pipes, even with good design and drip legs etc. Iron pipe is extremely robust and will withstand the highest impact forces and abuse of any of the other methods of constructing an air system. In the past iron pipe was the cheapest but cost of steel lately has been escalating rapidly so pipe could be expensive. Copper. I haven't priced copper lately so I don't know where it fits in the cost ranking. It is rather easy to work with if you are fairly skilled at sweat soldering with a torch. Copper is fairly soft so you do need to protect and locate the lines to avoid chance of impact damage. On the plus side you don't need the union fittings. Sweat fit joints can always be sweated open and then rejoined or the copper can be easily cut to put in new fittings or replace damaged sections by simply inserting new slip fit solder connections. I don't know what you already know about air systems, so if you already know all this, just ignore me and go on about your business. If not, then here's a couple of hints that might help. In any air system, IMHO, use the largest supply lines that are physically and economically practical. The larger lines help prevent downstream tools and equipment from being starved by upstream use, like when a shower suddenly turns hot when the toilet flushes. Also the larger lines effectively increase the size of your air "tank" even if only by a little. Don't forget to run the delivery system in a loop, not a straight line. That will also help to prevent any one unit from starving another. Never run lines level and horizontal. If possible, always run them at least 2 to 5 degrees downhill toward a drip leg, automatic drain or the tank. If at all possible, always put an automatic drain on the tank, it will save you a lot of maintenance and grief down the line and your air will be a lot drier at the delivery points. Put a drip leg at each air station, even if you have a water trap. When you put in an air station, go UP from the main line, over and then down to the station, this will again reduce the amount of moisture that reaches the final air outlet and this will be better for all your tools and equipment. Remember, every drip leg that does not have a automatic drain must be bled regularly, daily, weekly or monthly, depending on your usage. Notice that everything I've said tends to make water condensation run away from the end outlet. Water is your enemy. Design your system to be as dry as possible at the tool end. As for system design, don't run your delivery lines at tank pressure, put a LARGE cfm capacity regulator at the tank outlet. This will allow you to maintain a more consistent line pressure while the compressor is cycling. For example, set your compressor to cycle between 130 and 150 psi and then set you line pressure at 125 psi. That way your line pressure won't drop between compressor cycles. By the same token, set your line pressure a few psi higher than the highest pressure required by any of your tools or equipment and then of course, use the regulator at each station to set the psi for the particular tool or equipment in use at that station at that time. For my personal taste, I prefer a compressor that has just enough top end psi for the job but as much cfm as possible, YMMV. Hope I haven't bored you, hope this helps you or someone else. As usual all the above is strictly IMHO and if anyone has differing opinions or advice, don't hesitate to post. -- Michael Michael Powers Director of Operations Central Lighting & Equipment 1720 Fuller Rd.

Tough to attend everything at a 3 day conference and attend 5 shows in 6 nights - plus internet seems to never be free in London as it often is in the US. As Bill S. noted, it was a wonderful conference with over 300 folk from 31 countries. About the only place I know where you can here an architect from India discuss building spaces for traditional Indian performances and then here about the machinery at KA. Fascinating. I thought I'd like to report - over several posts - on some of the highlights. First, while primarily architects, engineers, and theatre consultants, there was a significant designer and technician group. That group over several presentations made some important points on design of theatre buildings that likely most of you all know and understand intuitively but I think they bear repeating. First, design the building so that it is easy to hang stuff anywhere - any place in the theatre or house and probably lobbies and other backstage spaces. Second, don't make things in concrete and don't weld anything. Similar message but at sometime in the life of the building it is likely that much of it will be in the way and there will be a desire to move it. While the complete prohibition on concrete and welding is extreme, the lesson is clear. Special mention for seating - don't use the typical theatre seat insert with a threaded stud anchored in the floor. Now to battle with the seat manufacturers. (I wish it were so easy as some folk think that one simply tells the builder what to do and it gets done that way.) Third, and more designer influenced, the upstage wall of a stage should be brick. Ponder that. I saw 5 shows and excluding 2 at Shakespeare's Globe, 2 of the other three used the brick wall as part of set design (I assume brick - could have been plastic brick applied to some other wall): Piccadilly and Cottlesloe. This will be hard to get very often but I think they are right. Fourth, from a wardrobe person, lots of plugs. There are so many things that plug in that I'm convinced continuous wiremold everywhere might not be excessive. Next up: The closing all-conference debate on flexible spaces and found spaces versus what is being built today. Bill C.

What do you mean by "the connector's strain relief"? I'm sure it's not your explanation that is flawed, I may not be reading this correctly (It's midnight). Could you re-phrase this for me? "Crackling" or "pop-ing" coming from the microphone due to a "breakage at the connector" has been a chronic problem everywhere that I've worked. I have yet to see a good solution/prevention for this (besides a budget for replacement microphones), therefore, I am very interested in understanding your fix (or near-fix). Just last weekend I assisted a solder job, replacing a microphone's connector, 20 minutes before curtain (we've run out of replacement microphones and are putting less-than-good microphones on stage). I'd prefer never again to be soldering a mic while the house is open. So please, all thoughts on protecting microphones and their connections are welcome. I know Chris typed this over a week ago, but I've been away from the list for a while. If you guys wouldn't mind re-hashing the thread for a student (me), I'd appreciate it.

If it are on your side, does it feel > strongly enough to override the superintendent's decision? I think several of the school board members (the ones I know) are decent people, but it's been my experience (at school board meetings - dealing with the charter high school I teach at - a separate school and issue from this facility talk) that this board is great at delegating to the admins what they want them to look in to, but basically they're pushovers by whatever the admins say. A little mumbo-jumbo from the Finance Director, and the board approves a motion. A little patronizing chatter from the Superintendent and the board approves another motion. This issue of the outside company being contracted to operate the space was not a board agenda issue - it was dealt with as an internal housekeeping issue. Like deciding who the toilet paper supplier would be. > If it doesn't agree with you, is the community strongly enough behind you > to make the school board members change their minds? Knowing some of the movers and shakers who have worked tirelessly to make this (facility) happen (including the Heritage Seat campaign, that has raised over $50K for equipment and an endowment), I suspect there's some more action being arranged behind the scenes that I don't know about. It's just that things move at a glacier's pace. (But the pessimist in me is worried that everyone feels defeated, and doesn't feel they can do any more.) There's really nothing else I personally can do - the admins see me as a bothersome, noisy troublemaker, not as someone with knowledge and experience in this field.

It doesn't matter how the admins feel. For one thing, if they truly feel that way about you, you won't be there much longer. What DOES matter is how the "movers and shakers" feel and how the board feels. You can still be useful. You probably have a better handle on what it would cost to administer the space than anyone else. Get the numbers together and compare them to the contract costs. Make up a list comparing the advantage/disadvantage of in-house control vs contracted control. Make sure that you include the historic problems of facility damage and how it can be reduced by in-house personnel. Then get the information to the movers and shakers and let them do their thing. The process will only be glacial if the local residents allow it to be that way. If enough noise is made, it will get prompt attention.
