1. What Is This Structure?

FOH means Front of House.

In concert and live-event production, the FOH structure provides elevated or protected working positions for technical personnel and production equipment.

Depending on the project, these positions may be used for functions such as:

• audio control;

• lighting control;

• video control;

• production coordination;

• technical monitoring.

However, this specific product should not simply be described as a “FOH booth.”

Its physical configuration is much larger and more vertical.

A better structural description is:

A multi-level Ringlock production-control tower containing elevated technical platforms, internal circulation and a covered upper working zone.

That distinction is important because the operational requirement is not only:

“Give the technician somewhere to stand.”

It is:

“Create several usable technical levels inside one temporary vertical structure.”

2. Primary Structural Function

The main function of the structure is to organize technical control positions vertically within a concert/event production area.

The original product page confirms the component quantities and packing information.

3. The Key Feature: This Is a Vertical FOH, Not a Single Platform

The most important thing to understand about this product is its vertical zoning.

A simple FOH structure may consist of:

Ground

↓

One Elevated Control Platform

↓

Canopy

This structure is different.

Its concept is closer to:

Ground Level

↓

Lower Technical Level

↓

Internal Access

↓

Middle Technical Level

↓

Internal Access

↓

Upper Technical Level

↓

Covered Top Zone

The exact operational assignment of each level is not stated in the BOQ, so DragonStructure should not invent labels such as “audio floor,” “lighting floor,” or “video floor.”

Instead, the correct structural description is:

The tower provides multiple platform levels that can be assigned to different production functions according to the event layout.

That keeps the structural fact separate from the customer's eventual equipment arrangement.

4. Overall Structural Configuration

The structure can be divided into five main systems:

A. Ringlock Main Frame

The main vertical skeleton consists of:

• 2m Ringlock pillars;

• 2m horizontal pipes;

• 1m horizontal pipes;

• 2.6m horizontal pipes;

• diagonal bracing;

• adjustable bases.

B. Technical Platform System

The working floors use:

• 1×2m aluminum-framed decks;

• 18mm anti-slip plywood surfaces;

• aluminum beam clamps.

C. Internal Vertical Access

Movement between levels is supported by:

• two internal stair units;

• three trap-door deck modules.

D. Upper Covered Zone

The BOQ includes:

• one roof system;

• top canopy;

• canopy on three sides.

E. Ground Adjustment System

The complete structure uses:

• 15 adjustable bases;

• confirmed adjustment height of 0.7m.

Together these systems turn the Ringlock frame into a usable multi-level technical-control structure, rather than simply a tall scaffold.

5. Ringlock Vertical Structure

The BOQ confirms:

51 × LR01 Pillars, 2m long.

These modular vertical standards create the main height of the FOH structure.

Because the source identifies the overall product as approximately 10m high and uses 2m standards, the structure follows a repeated modular vertical rhythm.

Conceptually:

0m

↓

2m

↓

4m

↓

6m

↓

8m

↓

10m

This does not mean that every 2m interval automatically contains a complete operational floor.

The BOQ and product configuration confirm a multi-level structure, but the exact function and finished platform arrangement at every elevation should follow the actual project drawing.

6. Three Horizontal Member Lengths

One interesting feature in this FOH BOQ is that it does not use only one horizontal-member length.

The confirmed quantities are:

• 200 × LR02 horizontal pipes, L = 2m

• 12 × LR02 horizontal pipes, L = 1m

• 40 × LR02 horizontal pipes, L = 2.6m

This immediately tells us that the FOH is not a simple uniform square tower.

Its Ringlock grid uses different bay dimensions to create the required platform geometry and internal working arrangement.

The dominant module is clearly:

2m

but the structure also incorporates:

1m

and

2.6m

horizontal relationships.

This mixed-bay configuration is one of the details that makes the product structurally more interesting than a generic Ringlock tower.

7. Diagonal Bracing

The BOQ includes:

44 × LR03 diagonal pipes matched to the 2m Ringlock bays.

At structural-breakdown level:

Vertical Standards

Horizontal Ledgers

create the modular spatial frame.

The diagonal members create the braced bays within that frame.

The actual brace positions should follow the project drawing and supplied configuration.

The quantity alone should not be converted into claims regarding:

• wind resistance;

• allowable lateral load;

• structural capacity;

• safety factor.

Those require project-specific verification.

8. Multi-Level Platform System

The FOH contains a substantial deck system.

The confirmed BOQ includes:

28 × 1×2m aluminum-framed platform decks

with:

18mm anti-slip plywood topping.

Each standard deck therefore provides:

1m × 2m = 2m²

of nominal deck surface.

Twenty-eight standard decks correspond geometrically to:

28 × 2m² = 56m²

of deck-module surface.

In addition, there are three trap-door deck modules.

This 56m² figure is only an arithmetic total of the 28 standard deck modules. It is not a claim that the FOH has one continuous 56m² floor or that all decks are installed at the same elevation.

That distinction matters because the decks are distributed through a multi-level tower.

9. Three Trap-Door Platforms

The BOQ separately lists:

3 × 1×2m trap-door stage toppings.

These are structurally and operationally different from the 28 ordinary platform decks.

A standard deck mainly creates usable floor area.

A trap-door deck also provides an access opening through the platform level.

This becomes particularly important in a vertically stacked FOH.

Instead of forcing technicians to circulate externally around the tower, the access arrangement can be integrated into the internal floor system.

Conceptually:

Working Platform

↓

Trap-Door Opening

↓

Internal Stair / Vertical Circulation

↓

Next Platform Level

This relationship between deck + trap door + stair is one of the defining characteristics of this product.

10. Internal Stairs

The BOQ confirms:

2 × internal stair units.

This is another major difference between a basic FOH platform and this 10m tower.

The stairs are not merely an external entrance stair leading from the ground to one platform.

They belong to the internal circulation system.

That means the structure has two separate functions happening at the same time:

Horizontal Function

The platform decks create working areas for technicians and equipment.

Vertical Function

The internal stairs and trap-door openings connect the working levels.

So the FOH should be understood as:

Technical Workspace

Vertical Circulation System

rather than simply:

Elevated Platform

11. Why Internal Access Matters in a Multi-Level FOH

Once a FOH becomes multi-level, access is no longer a small accessory issue.

The technician needs to move:

between technical levels

rather than merely:

from ground to platform.

That changes the structure conceptually.

A useful way of thinking about this tower is:

The decks create the rooms; the stairs create the circulation between those rooms.

Of course, these are temporary open structural levels rather than permanent building rooms, but the analogy helps explain why the access system is integral to the FOH configuration.

Without internal circulation, a tall frame containing several decks would not automatically become a practical multi-level control structure.

12. Aluminum Beam Clamps

The BOQ includes two beam-clamp lengths:

• 18 × 2m aluminum beam clamps

• 6 × 1m aluminum beam clamps

These components belong to the platform integration system.

The Ringlock frame and aluminum-framed decks are different component systems.

The beam-clamp components help integrate the platform arrangement with the supporting Ringlock grid in this supplied configuration.

This is a good example of why the FOH should not be described simply by counting Ringlock standards.

The complete working structure depends on the relationship between:

Ringlock Frame

and

Platform System

and

Access System

and

Weather-Cover System

13. Adjustable Base System

The BOQ confirms:

15 × stage adjustable bases, 0.7m high.

These form the ground interface for the Ringlock structure.

The 15-base count also tells us that the ground layout is more complex than a simple four-leg tower.

However, the source does not provide sufficient engineering information to convert the base arrangement into claims regarding:

• foundation requirement;

• ground bearing capacity;

• leveling range under actual loading;

• ballast;

• anchoring;

• overturning resistance.

Those should remain project-specific questions.

14. Roof and Three-Side Canopy

The BOQ confirms:

1 × Roof with 3 sides canopy and top canopy.

This is important because the upper part of the FOH is not simply an exposed working platform.

The configuration includes a covered zone consisting of:

Top Cover

Three-Side Cover

This supports the practical FOH function by creating a more enclosed technical-control area.

However, the source does not specify:

• canopy material;

• exact canopy dimensions;

• weather rating;

• wind rating;

• waterproof performance standard.

Therefore, the correct DragonStructure wording is covered upper work/control area, not an unsupported claim such as “all-weather FOH.”

15. FOH Is About Function, Not Just Height

It would be easy to market this product as a:

10m Ringlock Tower

but that misses its real identity.

The important characteristic is not simply:

10m high

but:

10m vertical Ringlock framework + distributed working platforms + internal access + covered upper technical area.

That combination turns the structure into a production-control tower.

This is also why it belongs primarily under FOH & Control Structure, rather than Working Platform Structure or generic Ringlock Structure.

DragonStructure classification prioritizes what the complete structure is designed to do, rather than simply which physical components are used.

16. Functional Relationship Between the Modules

The complete structure can be read as four interacting layers:

Structural Frame

Standards + Horizontal Ledgers + Diagonal Bracing

create the multi-level Ringlock framework.

Working Floors

1×2m decks + beam clamps

convert selected levels into technical working platforms.

Vertical Circulation

Internal stairs + trap-door decks

allow movement between platform levels.

Environmental Separation

Top canopy + three-side canopy

creates a covered technical-control zone at the upper part of the structure.

So the structure is not a collection of unrelated Ringlock parts.

Its functional logic is:

Frame

→ Platforms

→ Access

→ Control Workspace

17. Confirmed BOQ

Packing Weight: approximately 4500kg

Packing Volume: approximately 9CBM.

18. What the BOQ Tells Us About This FOH

Several BOQ numbers reveal the nature of the structure immediately.

51 Vertical Standards

This is a substantial multi-level Ringlock framework, not a compact booth.

252 Horizontal Members

The structure contains:

200 + 12 + 40 = 252 horizontal pipes

across three different lengths.

That confirms a relatively complex modular grid.

31 Platform Modules

There are:

28 standard decks + 3 trap-door decks = 31 deck modules.

This shows that usable platform area is distributed through the tower.

2 Internal Stairs + 3 Trap Doors

This combination strongly distinguishes the FOH from a simple single-level technical platform.

15 Adjustable Bases

The structure has a significantly larger ground arrangement than a simple four-corner tower.

Taken together, the BOQ describes:

a multi-bay, multi-level production structure with integrated technical floors and internal circulation.

19. Assembly Logic

At structural-breakdown level, the system can be understood in the following sequence:

1. Establish the confirmed ground layout and 15 adjustable-base positions.

2. Install the lower Ringlock standards.

3. Connect the first level of 1m, 2m and 2.6m horizontal ledgers according to the drawing.

4. Install the corresponding diagonal members.

5. Build the first required technical platform level.

6. Integrate the aluminum-framed decks with the Ringlock support grid.

7. Position trap-door decks where internal vertical circulation is required.

8. Install the first internal stair connection.

9. Continue the Ringlock frame upward in modular levels.

10. Add subsequent working-platform levels according to the FOH configuration.

11. Continue the internal access path using the second stair and relevant trap-door opening.

12. Complete the upper Ringlock framework.

13. Install the top and three-side canopy system.

14. Configure the finished platform levels for the required production-control functions.

This is an explanation of the modular assembly logic, not a complete engineered erection procedure.

20. Working Levels Can Serve Different Technical Functions

A multi-level FOH is useful because the available working zones can be assigned according to the production layout.

Depending on the project, individual levels might accommodate:

• audio consoles;

• lighting consoles;

• video/control equipment;

• communications;

• production staff;

• technical monitoring positions.

But these are possible applications, not confirmed assignments for this exact historical configuration.

Before producing a similar FOH, the customer should identify what each platform level is intended to do.

That information can change:

• platform layout;

• equipment space;

• access;

• cable routing;

• canopy requirement;

• final BOQ.

21. Equipment Layout Matters

FOH is not simply about creating enough square meters.

Technical equipment has practical dimensions.

For example, a production position may need space for:

Console

Operator

Equipment Rack

Cable Area

Circulation

Therefore, when adapting this structure, it is better to start with:

What equipment needs to be accommodated on each level?

rather than simply:

How big should the FOH be?

This is a structural-planning question rather than an engineering calculation.

22. Cable Routing Should Be Considered Early

A multi-level technical tower naturally creates vertical cable routes.

The supplied BOQ does not identify dedicated cable trays or cable-management components, so they should not be presented as included equipment.

But during project planning, it is useful to define:

• where cables enter the FOH;

• which level each cable must reach;

• whether cable routes interfere with stairs;

• whether openings through platforms are needed;

• whether equipment racks require dedicated positions.

For a technical-control structure, circulation is not only about people.

It is also about equipment and cables.

23. Difference from a Small FOH Booth

A compact FOH and this structure solve related but different problems.

Therefore, this product deserves its own DragonStructure page rather than becoming merely a “larger version” of the 2×2m FOH.

24. Suitable Applications

This configuration can be considered for:

• concert FOH control;

• music festivals;

• outdoor live-event production;

• large production-control positions;

• multi-department technical control;

• audio/light/video production areas;

• temporary elevated technical workspaces;

• events requiring vertically separated control positions.

The actual use of each platform level should be confirmed project by project.

25. Customization Variables

A similar FOH structure can change substantially according to the project.

Overall Height

This configuration is approximately 10m.

Other projects may require fewer or more vertical levels.

Ground Footprint

The footprint should be developed from:

• equipment quantity;

• required platform area;

• circulation;

• available site space.

Number of Working Levels

Not every FOH needs the same number of platforms.

Platform Layout

This configuration uses:

28 standard 1×2m decks

3 trap-door 1×2m decks.

A different layout will change the deck and support quantities.

Stair Arrangement

This configuration contains two internal stairs.

Different working-level relationships may require a different access arrangement.

Canopy Configuration

This structure includes a top and three-side canopy.

The required enclosure should be defined according to the project.

Equipment Arrangement

Provide console and equipment dimensions rather than assuming all FOH systems need identical working areas.

Cable Management

Cable routes and platform penetrations should be considered when defining the final layout.

26. Information Needed for a Similar FOH Structure

For a new quotation or structural proposal, provide:

• required overall height;

• required footprint;

• number of technical levels;

• height of each required working level;

• intended function of each level;

• audio-console dimensions;

• lighting-console dimensions;

• video/control equipment dimensions;

• equipment/rack quantities;

• expected personnel positions;

• stair/access preference;

• required canopy/enclosure;

• cable-routing requirements;

• existing Ringlock components, if any;

• site drawing;

• FOH position relative to the main stage;

• site photos;

• indoor/outdoor use;

• relevant ground/site information.

A useful planning sequence is:

Production Functions

→ Equipment

→ Working Levels

→ Platform Areas

→ Vertical Circulation

→ Ringlock Grid

→ Canopy

→ Final BOQ

Experience-Based Structural Interpretation

Based on the supplied BOQ and normal Ringlock/FOH configuration logic:

• the FOH uses several vertical working zones rather than one isolated platform;

• the mix of 1m, 2m and 2.6m ledgers indicates a non-uniform multi-bay plan;

• trap-door decks and internal stairs form the internal circulation system;

• the platform system and Ringlock frame work together to create usable technical levels;

• the top and three-side canopy forms a more protected upper control zone.

These are structural interpretations, not formal engineering calculations.

Not Established by the Supplied Information

The supplied material does not establish:

• allowable platform load;

• allowable equipment load per level;

• maximum occupancy;

• crowd/personnel load;

• allowable console/rack weight;

• wind rating;

• canopy wind resistance;

• allowable operating wind speed;

• ballast requirement;

• anchoring requirement;

• foundation requirement;

• ground bearing requirement;

• safety factor;

• guardrail performance;

• certification;

• code compliance;

• engineering approval.

These should be verified according to the final project, equipment layout, site and applicable requirements.

DragonStructure's governing rules explicitly prohibit turning practical configuration experience into unsupported engineering conclusions.

FAQ

What makes this different from a normal single-level FOH?

This is an approximately 10m-high multi-level structure. It combines distributed technical platforms with internal stairs and trap-door decks, rather than creating only one elevated control floor.

How many platform decks are included?

The BOQ contains 28 standard 1×2m decks and 3 trap-door 1×2m decks, for 31 deck modules in total.

Why does the FOH use trap-door decks?

They provide openings within selected platform levels so the internal access system can connect different elevations without treating every platform as a completely closed floor.

Are the two stairs entrance stairs?

The source identifies them as “stairs inside.” They should therefore be described as part of the internal access/circulation arrangement rather than automatically as external entrance stairs.

Why are there 1m, 2m and 2.6m Ringlock ledgers?

The confirmed BOQ uses all three lengths, indicating that the complete FOH uses different bay dimensions rather than one uniform square grid. The exact location of each length should follow the drawing.

Does every 2m height become a working floor?

Not necessarily. The 2m standards create the modular vertical framework, but actual working-platform positions depend on the configured deck arrangement.

Is the top of the FOH covered?

Yes. The BOQ specifies one roof with three-side canopy and top canopy.

Is the canopy weather-rated?

No such rating is established by the supplied information. Wind resistance, weather performance and any project-specific requirements should be separately verified.

Can different floors be used for sound, lighting and video?

Yes as a functional planning concept, but this exact source does not assign a confirmed department to each level. The intended equipment and operator layout should be defined before finalizing a new configuration.

Can the same BOQ simply be reused for another 10m FOH?

Not automatically. Height alone does not determine the BOQ. Footprint, working levels, equipment arrangement, stair locations, platform layout, canopy and site requirements can all change component quantities.
