BelleVue Country Club Presents

Tentôrium Tent

TENTORIUM is a portable smart tent; giant, substantial, tremendous ; dismountable, easy to move, installed and dismantled in record time, environmental friendly, safe, fire proof, non flammable and resistant to adverse weather

conditions.

(Concept Introduction)

BCC presents an innovative and groundbreaking concept in the field of portable smart tent design,

marketed under the brand name TENTORIUM.

TENTORIUM is a portable smart tent of monumental scale; giant, substantial, and tremendous in size

and capacity. It is fully dis-mountable, easy to transport, and can be installed and dismantled in

record time. The structure is environmentally friendly, highly safe, fireproof, non-flammable, and

resistant to adverse and extreme weather conditions.

TENTORIUM is designed to be fully independent and self-sufficient. It is equipped with modular

cubicles accommodating a comprehensive range of facilities and services, including pantries, coffee

shops, power generator systems, HVAC systems, videography and broadcasting facilities,

surveillance and security systems, ticketing windows, first aid clinics, fully self-contained lavatories,

storage units, and a dedicated lightning absorption chamber.

TENTORIUM regular series comprises three standard types forming a polygonal cone-shaped

structure: small, medium, and large. These variants have diameters of 75 / 112 / 150 meters,

covering areas of 5,000 / 10,000 / 20,000 square meters respectively. The frontage heights are

7 / 10 / 13 meters, while the internal roof heights reach 25 / 40 / 55 meters. The corresponding

weights are approximately 1,250 / 2,500 / 5,000 metric tons, and each configuration is capable of

accommodating 2,000 / 4,000 / 8,000 individuals respectively.

TENTORIUM will be submitted to the Guinness World Records to be recognized as the largest

portable tent in the world. The concept has been registered under intellectual property rights in

Lebanon and is in the process of applying for a patent with the World Intellectual Property

Organization (WIPO).

The slogan of TENTORIUM is “Safety First.” The structure has undergone the necessary structural

analysis and engineering design. (Which should be verified and approved by Bureau Veritas and

SOCOTEC, and to obtain certification from the International Organization for Standardization (ISO)

and will be insured by well-known international insurance firms, depending on the specific

geographical location.)

The TENTORIUM tent is envisioned as an architectural edifice akin to a ship recovered from the

oceans and seas, transported to the foothills of the Akkar Mountains in Lebanon, then transiting

through the mirages of the deserts of the Kingdom of Saudi Arabia and the Gulf, to finally be

moored in the public squares of capitals and cities worldwide.

As for the intended objective and the greatest dream of the innovator (Mohamad A. Daher), it is to

transform this metaphorical “ship” tent into a tangible reality and to restore this edifice to the place

from which it was metaphorically recovered.

1/2(Design, Specification & Methodology)

The structural design concept of TENTORIUM is based on trigonometric principles, specifically the

30° / 60° / 90° triangle, and adopts, as much as possible, the Fibonacci sequence and the golden

ratio (phi ɸ).

The applied technology consists of a dual tightening cabling system, shipping standard container

units, bespoke structural components, container corners and accessories, marine-grade lashing

equipment, and various maritime turnbuckles and shackles. All these elements have obtained

international design approval, quality pre-approval, and certification.

The TENTORIUM design specification features a peripheral enclosure composed of a series of

shipping standard container units used as frontage, stacked in a polygonal configuration, either

longitudinally and/or transversely. These units are elevated by adjustable skids positioned on one of

the two sides of the polygon, with adjustable angled panels in between. These panels incorporate

light-penetration windows and pull-up openings equipped with emergency exit doors.

The container units also function as anchoring elements for tightening the pitched roof dual cabling

system. This system is stretched from a top notch positioned at the apex of the central column and is

secured to the ground by deep-row anchor bolts, further supported by multiple boulder

counterweight blocks.

The TENTORIUM textile roof is composed of a specially tailored PTFE fabric structure.

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene with numerous

applications and is commonly known under the trade name Teflon. It exhibits the following

characteristics:

• High resistance to weather conditions and immunity to ultraviolet radiation

• Very high tensile strength

• Fireproof and non-flammable properties

• High solar reflection capability

• Self-cleaning surface characteristics

The architectural methodology of TENTORIUM includes a colossal entrance porch supported by a

single vertical pestle, and a conical roof that is polygonal in plan on a flat plane, using shipping

container units as the peripheral frontage. The structure rises to a single apex, forming a cone shape

composed of one central column acting as a tripod system. This column incorporates a rotating

central podium and allows for maximum internal spacing with completely unobstructed 360-degree

visibility.

The upper section of the central column integrates a firefighting water tank system, followed by a

prefabricated cowl used as an air extraction system, and is topped by a telescopic pinnacle carrying

the logo flagpole, a warning flashing light, and a lightning rod.

TENTORIUM – Engineering and Cost Philosophy – 1,700 USD per m²

Epoxy Marine Steel Mega-Structure – Fully Demountable, Self-Balanced Tent System

1. Project Definition

TENTORIUM is a giant, fully demountable, transportable tent (mega-structure) engineered for

high-capacity public use.

It is suitable for deployment in urban plazas, public parks, desert environments, coastal zones,

and o shore-adjacent installations.

Key Features:

• Operates as a self-balanced engineered system, eliminating the need for permanent civil

foundations.

• Combines marine-grade durability, modular architectural flexibility, and long-term

reusability.

2. Deployment Sizes and Structural Mass

• A 5,000 m² tent carries approximately 1,250 metric tons.

• A 10,000 m² tent carries approximately 2,500 metric tons.

• A 20,000 m² tent carries approximately 5,000 metric tons.

Note: Structural mass increases proportionally with span, wind exposure, live load, occupancy

capacity, and integrated systems.3. Counterweight Engineering System

• TENTORIUM tent is stabilized via a fully engineered counterweight system.

• Counterweights are calculated as part of the structural load model and fabricated in

advance within the beneficiary country using local concrete and steel.

• They are not transported internationally and do not require on-site casting.

This ensures logistical e iciency, structural precision, and economic rationality.

4. International Cost Benchmark

• Reference Price: ≈ 1,700 USD/m²

• Represents full structural, architectural, mechanical, and safety integration.

• Unit cost remains constant regardless of total area, because structural responsibility

increases with size:

Mega-Tent vs. Iconic Dome – Inflation-Adjusted Cost Comparison

TENTORIUM – Mobile Mega-Tent

TENTORIUM is a fully portable, self-balanced mega-tent designed for multiple deployments.

Heights range 15-40-55 meters, and typical areas span 5,000 to 20,000 square meters. The cost per

square meter is 1,700 USD, adjusted for current market conditions. Its key advantage is mobility

and reusability, allowing operation in urban plazas, parks, deserts, and coastal zones without

permanent foundations, making it extremely cost-e ective for large-scale temporary or semi-

permanent applications.

Khan Shatyr – Astana, Kazakhstan

Opened in 2010, Khan Shatyr is a permanent tensile mega-tent covering over 100,000 square

meters with a central mast reaching 150 meters. Original cost was ~4,000 USD per square meter.

Adjusted for 14 years of average construction inflation (~4.5% annually), the current cost per

square meter is roughly 7,300 USD. It is designed for long-term public use with integrated retail,

entertainment, and recreational facilities.

 Jeddah Super Dome – Saudi Arabia

The Jeddah Super Dome is a permanent high-end dome covering 34,000 square meters. Original

construction cost was about 1.2 billion SAR (≈320 million USD), giving an initial cost of ~9,400 USD

per square meter. Adjusted for eight years of Saudi construction inflation, including post-COVID

impacts, the current cost per square meter is roughly 12,000 USD. The dome is permanent, with

fully integrated utilities, safety systems, and architectural complexity.

Comparison Summary (Per Square Meter)

• TENTORIUM: 1,700 USD/m² – Mobile, reusable, highly cost-e icient.

• Khan Shatyr: ~7,300 USD/m² – Permanent tensile mega-tent, iconic design.

• Jeddah Super Dome: ~12,000 USD/m² – Permanent high-end dome, full facilities.

Key Observation

TENTORIUM remains significantly more affordable per square meter compared to the largest

permanent mega-structures in the world. Its mobility, reusability, and modularity provide

unmatched cost e iciency while maintaining structural integrity and large-scale capacity. Even

after adjusting for inflation, the difference is substantial: TENTORIUM is over 4 times cheaper than

Khan Shatyr and over 7 times cheaper than the Jeddah Super Dome.
