Site-Specific Pressure & Loads

Industrial Application Range

One Continuous Air-Supported Envelope. Ten Very Different Operations.

The building geometry remains rectangular and elongated. Internal clearances, end-wall doors, airlocks, pressure controls, ventilation and foundations are configured around the actual operating envelope.

Aircraft MRO

Airliner maintenance platforms, engine work and apron interfaces.

Oversized Submarine Overhaul

Dry-dock hull access, crane clearance and marine environmental control.

Commercial Ship Construction

Slipway enclosure, corrosion-control and large hull fabrication.

Yacht Build & Refit

Controlled finishing, composites, painting and joinery operations.

Automotive & Heavy Vehicles

Vehicle assembly, bus and truck service and flexible production cells.

Heavy Industry Fabrication

Large pressure vessels, turbines and oversized equipment assembly.

Environmental Bulk Storage

Dust-controlled mineral stockpiles and conveyor integration.

Rail Maintenance

Multiple tracks, inspection pits and locomotive overhaul.

Football Training

Full-size pitch, lighting, ventilation and spectator support.

Aquatic Centre

Competition pool, humidity control and corrosion-resistant envelope.

System Definition

Not a Spherical Bubble. Not a Corrugated Steel Arch.

The Spanbest air-supported system uses a long rectangular footprint and a continuous barrel-vault membrane section. External cables restrain and stabilize the membrane envelope; the interior remains free from roof trusses and columns.

Rectangular plan and long-axis operational layout
Continuous barrel-vault pneumatic envelope
External steel cable net and perimeter concrete anchorage
Project-specific end walls, hangar doors, airlocks and service penetrations
Redundant pressure, ventilation, emergency power and monitoring systems

Engineering Inputs Required

Final Configuration Is Calculated Per Project

The following remain TBD until the site and operating brief are confirmed:

Span, length and apex clearance

Wind, snow and seismic loads

Soil and perimeter foundation

Operating pressure and redundancy

Doors, airlocks and equipment paths

HVAC, humidity and dust control

Application Drawing Series

Ten Concept Layouts for Industrial and Sports Operations

Selection drawings are conceptual only; final PE-stamped drawings require confirmed site loads, equipment envelopes and geotechnical data.
