Built Fast, Built Right Rigid-frame fabric buildings can also be completed in far less time from start to finish than traditional brick-and-mortar buildings. While the time to build the framework is similar for a fabric building and a metal-clad structure, fabric panels can be applied in one-third the time needed to screw down metal siding. A big reason for the overall reduction in fabric building lead time is that companies like Legacy are full-service suppliers who can handle every step in the process from start to finish. By employing their own design engineers, manufacturing fabric panels and I-beams in their own facilities, and sending their own in-house professional installation crews to every jobsite, these companies can ensure full quality control and constantly keep projects moving, without any of the unexpected delays experienced by those relying on outside vendors. All things considered, tension fabric structures offer exceptional value for sports venues large and small. From proven structural integrity to a high level of interior finish and craftsmanship, rigid-frame fabric buildings make it possible for any entity to obtain a facility they can be extremely proud of, without breaking the bank.

Hanging Tough Because of the airtight nature of a lined fabric building, air flow is very important, and passive ventilation alone is not enough for most athletic structures. Users will need some sort of mechanical means to at least move air, if not also heat or condition it. Often this means the inclusion of fans or an HVAC system suspended from the building frame above. For a rigid-frame design, supporting hanging loads like HVAC, fire suppression systems and lighting isn’t difficult, although it does need to be considered in the original design. Engineers use finite element analysis software to calculate the stresses for each individual I-beam, rather than over-engineering the entire structure and adding unneces- sary cost. Likewise, many sports facilities need to accommodate items such as scoreboards, video platforms, court dividers and netting. Some will even need to add mezzanines for spectator seating. By working with the customer to account for every potential collateral load, building de- signers can simply modify the rigid frame to add the necessary strength for those loads. Added Touches While project managers may be primarily focused on getting the most bang for the buck from a fabric building, of course it’s also common to need to appease certain stakeholders with additional flourishes, such as exterior facades containing brick or stonework. While these elements will add cost, the straight sidewalls of a rigid-frame structure do make it possible to easily include these types of touches. Another possibility with I-beam design is adding a fabric-clad ad- dition to the gabled end of an existing structure. Designers need to consider snow loads and rain runoff for the original building and new addition, among other compatibility factors, but for situations where expansion is a more cost-effective solution than new construction, it often can be done.
