Indoors you inherit a rig. Outdoors you bring one, and you bring the building too.
That is the whole trade, and every figure below is a way of measuring one side of it.
An indoor venue has already spent the money. The points are hung, the panels are landed, the dock is poured and the system is tuned to the room. What arrives on the truck is the part of the show that is particular to this show, and the building supplies the rest. The cost of that is that the building also decides a great deal, and it decided most of it years before the date.
Open ground has none of that and withholds none of it. There is no grid, so the trim is whatever the structure is rated to carry; no panel, so the power is a tie-in or a generator; no dock, so the load-in is whatever the ground will take a truck across. Nothing is fixed, which is the attraction, and nothing is provided, which is the bill.
What follows is not a list of advantages. It is four documents — two theatre technical specifications and two pages from one city — read for the figures that actually move a plan.
A theatre publishes its hanging positions down to the one that does not exist.
The Kravis Center for the Performing Arts publishes a technical specification for each of its houses. These are its figures, read from those documents on October 10, 2026.
Read those two together and the useful point is not that one room is bigger. It is that both of them have already answered the question a rigging plot exists to ask. The positions are drawn, the heights are stated, and the document goes as far as recording that line set 78 does not exist — a detail that is worthless until the afternoon a plot is numbered against the schedule, and then saves an hour.
On open ground that document is the thing being produced rather than the thing being read. Every point is a point somebody has to stand up, and what it can carry is a function of the structure rather than of the building. That is a separate decision with separate published figures, and it is set out in the comparison of a mobile stage against a modular one.
- Dreyfoos Hall — a 100-foot grid over 2,195 seats
Ninety-one available line sets, single purchase and hand operated with compensators, worked from an operating gallery 35 feet above the stage right deck. All of them are truss battens, 76 feet long with 3-foot extensions stage left and right; line set 91 runs 85 feet. The grid is steel subway grating with wells on centreline and at 11′-6″, 23′, 34′-6″ and 46′. The proscenium is 60 feet wide and 40 feet high, with an adjustable header that brings it down to 32 feet. There is one 1-ton chain motor upstage left to the grid.
- Rinker Playhouse — a tension wire grid over 305 seats
A black box with no fixed seating: a retracting riser holding 195, with room for roughly 110 more on the floor depending on the stage area. Instead of a fly system it has a custom SkyDeck tension wire grid, with overhead electrics centred in 15-inch open wells and Schedule 40 pipe attached at each well to make the hanging positions. Configured as a proscenium house the opening is 28 feet wide by 16 feet high, and there is a hanging position above the control booth 30′7″ from the floor.
The seat count does not predict the service. The published panel does.
Both figures below are from the same organisation’s own technical documents, for two rooms on one campus.
The 305-seat room publishes a single service twice the size of any one company service in the 2,195-seat room. That is not an error in either document. A proscenium house with ninety-one line sets distributes its load around the stage in matched pairs at two voltages, because what plugs in there is a touring package arriving in several places at once; a black box puts everything in one room and gives it one panel. The lesson is narrow and worth having: ask what the panel says, because the size of the room will not tell you.
Outdoors there is no panel to ask about. The two honest answers are a tie-in that a licensed electrician engineers against a service that was installed for something else, or generators sized to the plot with fuel and a silencer and somewhere to put them. Neither is a problem. Both are a line on a schedule that the indoor version of the same show does not have.
One detail from the indoor document is worth carrying outdoors anyway. Dreyfoos Hall publishes a dedicated shore service in the receiving area — power for vehicles, at the dock, separate from anything feeding the stage. A site with no building has to decide where that comes from too, and it is the item most often remembered at the point the trucks are already parked.
- Dreyfoos Hall — six services, none larger than 200 amps
A 3-phase 200-amp 120/208 service for sound equipment on the stage left wall at deck level. Four company services: 100 amps at 120/208 and 100 amps at 277/480 on the upstage left wall at grid level, and the same pair on the downstage right forestage grid. A 3-phase 200-amp 120/208 shore service in the receiving area.
- Rinker Playhouse — one service, 400 amps
A single 3-phase, 400-amp, 120/208 panel in the receiving area, feeding a room with 190 twenty-amp dimmers and an ETC Ion.
Two houses, one dock, and an eight-foot opening between the truck and the stage.
The published loading figures are identical for both rooms, because both rooms load through the same place.
Three bays, two of them with mechanical dock levellers. The dock is 4 feet high with 2,100 square feet of receiving room behind it. The loading doors are 8 feet wide by 12 feet high. Long-term truck and bus parking is arranged in advance with the technical director rather than assumed.
The eight feet is the figure that changes a drawing. Anything wider than eight feet assembled does not enter the building assembled — it enters as parts and becomes itself inside, which is time, and sometimes a different design. A 2,195-seat auditorium with a 100-foot grid and a 60-foot proscenium is reached through a doorway narrower than the stage of the black box next door.
Open ground has no door at all, and that is the clearest single advantage on the outdoor side of this comparison. Nothing has a width limit; a structure arrives at the size it will be. What replaces the door is the ground: whether a loaded truck can reach the position without crossing turf it would rut, whether the surface needs protection, and whether the route in is also the route out at two in the morning.
The rig you did not have to truck is also the rig you do not get to move.
Published installed systems, named because the venues publish them. Nothing here is a statement about what this company owns.
That analogue split stage left is the sentence a touring engineer reads first, because it is the difference between inserting a desk into this building and feeding one. A split that serves both snake systems means a visiting console can take its own copy of the inputs rather than borrowing the house one. Not every room publishes that, and the rooms that do not generally say so in the same document — which is why the audio advance is a reading exercise before it is a conversation.
The lighting note cuts the other way and is the better example of what an indoor room costs. A permanent wash that is neither colorable nor focusable is free and it is fixed, and a plot drawn without reading that line will arrive expecting to control light that cannot be controlled. Strips whose relocation is discouraged in the venue’s own document are, in practice, strips that stay where they are.
Outdoors nothing is installed and nothing is discouraged. Every fixture, every metre of cable and every position is a decision, which is why an outdoor plot takes longer to draw and shorter to argue about.
- What Dreyfoos Hall publishes at front of house
An AVID S6L-32D of 96 channels with an E6L-192 engine, two AVB cards, four DSP cards, an HDX card and a WSG-HD card. House and monitor consoles are independent, with separate snake heads and separate gain control, connected to those snake heads by fibre. There is an analogue split snake stage left feeding both snake systems.
- What Rinker Playhouse publishes
A permanently installed system with an Avid Venue PROFILE 48×16, Powersoft amplifiers, and crossovers and EQ on internal DSP. The sound console position is on the catwalk.
- What Dreyfoos Hall publishes about its lighting, which is the part to read twice
A permanently installed front-of-house concert lighting system over the thrust: a full area wash from directly overhead made of 6×16 lekos at 575w, four built-in conductor’s specials and five solo specials of 6×22 lekos at 1000w. The document states plainly that they are not colorable or focusable. Four line sets of Altman Spectra Strip RGBW light an orchestra upstage of the proscenium, and the document records that removal or relocation of those strips is not practical and highly discouraged.
Indoors you send a rider. Outdoors a city wants a traffic plan and an accountant.
From the City of Weston’s own special event permit page and its published event permit application, read October 10, 2026. Other cities differ; the shape of the thing does not.
The lead time is the figure to plan against. The application "shall be submitted not less than sixty (60) days prior to the commencement date of the event." Sixty days is longer than many outdoor events exist as a confirmed idea, and it is the reason the indoor-or-outdoor decision is usually made earlier than people expect rather than later.
What goes with it is a plan for traffic management, a plan for crowd control, a plan for waste disposal, a list of police and fire protection facilities available at or near the site, a certificate of insurance naming the City as an additional insured to stated minimum limits, and a hold harmless agreement on the City’s own form. Street closures are to comply with MUTCD standards. The application also calls for a projected financial statement including a balance sheet, an income statement and a statement of changes in financial position, certified by a certified public accountant — which is a genuinely unusual requirement and not one any technical department can satisfy.
The tent is the item that catches people. The city’s own page is unambiguous: if the event includes a tent or any other temporary structure, a proper building permit is required, and events involving tents, cooking or electrical power may also need permits from the building department and the fire marshal’s bureau. A tent is not an alternative to choosing a building. It is a building, with a building’s paperwork, on a site that also needs the event permit.
And one line decides more outdoor dates than the weather does: "No more than one special event shall be permitted at any park at one time." Park ground is not merely bookable or not. It is bookable by one event, and the calendar is a queue.
Four questions, all four answerable from documents already published.
None of them is about rain. Rain is a plan, not a venue type.
- Does the show need a point the building does not have?
If the plot hangs inside the published grid, on positions the venue prints, the indoor room is doing work nobody has to pay to recreate. If it does not — if the trim, the span or the load falls outside what the house publishes — then the structure is being brought either way, and open ground stops being the expensive option.
- Does the show need more than the panel publishes?
Add the plot up and read it against the stated service. A room with four 100-amp company services at two voltages is a different proposition from a room with one 400-amp panel, and the one that suits a given show is not the one with more seats.
- Does anything exceed the door assembled?
Eight feet wide by twelve high, at the venue above. Measure the widest assembled item on the truck against whatever the chosen building publishes, before the drawing is finished rather than after.
- Is the date more than sixty days out?
If it is not, and the event is outdoors on public ground, the question has already been answered by the calendar. That is worth checking first, because it is the only one of the four that cannot be solved with money.
There is no general answer, and the venue-marketing version of this comparison — atmosphere against certainty, charm against control — is not wrong so much as unusable. The usable version is that both options publish what they will and will not do, in documents written for technical departments and left where anyone can read them. A grid height, a line set count, an amperage, a door width, a lead time in days: five figures, four of them free to look up and one of them a phone call, and between them they decide the question long before anybody has to have an opinion about the sky.
Where the figures come from
- 100′ grid; 91 line sets; 76′ truss battens with 3′ extensions; line set 91 at 85′; operating gallery 35′ above the stage right deck; 60′ × 40′ proscenium with a 32′ adjustable header; 2,195 seats — The Kravis Center for the Performing Arts’ own published Dreyfoos Hall technical specification, kravis.org, read October 10, 2026. The same document carries the grid-well positions, the record that line set 78 does not exist, and the upstage left 1-ton chain motor.
- 3-phase 200A 120/208 sound at the stage left deck; 100A 120/208 and 100A 277/480 company upstage left at grid; the same pair downstage right at the forestage grid; 3-phase 200A shore in the receiving area — The same Dreyfoos Hall document, panel schedule. The front-of-house console, split snake and concert lighting wording quoted in §05 are from its sound and lighting sections.
- 305 maximum seating, 195 on the riser; custom SkyDeck tension wire grid with 15″ wells and Schedule 40 pipe; 28′0″ × 16′ standard proscenium configuration; one 3-phase 400A 120/208 panel; 190 20-amp dimmers — The Kravis Center’s own published Rinker Playhouse technical specification, kravis.org, read the same day. The installed console and amplifier wording in §05 is from its sound section.
- 3 bays, 2 with mechanical levellers; dock 4′ high; 2,100 sq ft receiving room; loading doors 8′W × 12′H — Published identically in both Kravis Center documents, because both houses load through the same dock.
- Sixty (60) days; traffic, crowd control and waste disposal plans; police and fire facilities list; certificate of insurance; hold harmless on the City form; CPA-certified projected financial statement; MUTCD for street closures — The City of Weston’s own published event permit application, westonfl.org, read October 10, 2026. Minimum insurance limits are stated on the form and are deliberately not reproduced here.
- Tent or any other temporary structure requires a building permit; tents, cooking or electrical power may require the building department and the fire marshal’s bureau; one special event per park at a time — The City of Weston’s own Special Event Permits page, same date, which also points to Chapter 100 and § 100.04(D) of its Code of Ordinances. Nothing here states what this company owns — manufacturers and venues are named because the specifications are theirs and are published. No system, fixture or room on this page is claimed as inventory, and no figure on it is a price.
