Case Studies

Client Testimonial

"Having this structure, the schedule went just like it would in the Summer. Normal Winter conditions up here (Colorado Mountains) would have doubled or tripled the time frame. Now it's coming on Spring time and we're done with our foundation work while everybody else is just getting started."

About Tension Fabric Structures

A Tension Fabric Structure (or TFS) is much more than just a tent. It is an all-weather fabric structure made from engineered, custom extruded aluminum alloy frame and high-grade architectural fabric, the TFS stands apart from other fabric structures, making them ideal enclosures for your construction project.

Flat end design for flexible accessory placement & maximum usable space.
Multiple personnel & equipment door options.
Curved eve framework allows snow to shed easily & creates high center height for operation of heavy equipment.
When penetration of the ground is not permitted, TFS ballasts can be used to meet engineering loads
Horizontal tensioning of the roof panels creates a sealed building allowing structures to maintain negative pressure.
Proprietary crane lift kits make moving a fully assembled TFS easy for multiple relocations.
