Whether you start with a complete building spec or just an idea, our team will provide the level of support and partnership you need.

Step 1


Before construction begins, our experienced team partners with you to discuss building specifications. Your niche sales and project design consultant may make recommendations to add efficiencies to the building, or to lower the cost or build time.

Building designers will use specialized software to design the building to your specification. If plans are already drawn by an architect or engineer, those plans will be translated to fabric and the fabric tension loads are added as needed. Completed building drawings are submitted for approval and revised as needed.


Step 2


Our in-house engineer staff is experienced in all aspects of fabric structures and regularly consults with the construction crews, designers and leadership to present creative solutions to customer needs.

All building designs are stamped by an engineer licensed in the building’s jurisdiction, who relies on current copies of the International Building Code and its applicable supplements, the relevant state codes and other applicable standards. Learn more.

Step 3


Component manufacturing is completed at our 70,000 square-foot in-house facilities. Components are manufactured at our South Haven, Minnesota, facility using ISO 9001:2015-certified practices.

ExxoTec™ fabric panels are created in our onsite climate-controlled manufacturing facility. Each bolt of fabric is quality tested and tracked to the final location on the building. The fabric is handled and cut to maintain biaxial tension, which eliminates friction on the final building and lengthens the life of the fabric.

Individual fabric panels are carefully measured and cut before being heat-welded to create a weatherproof cover. Each panel is rolled and wrapped for transportation to the jobsite.

Steel I-beams and small components are manufactured from 55 ksi steel. Depending on the building specifications, the steel utilized is 10-gauge to 1-inch or thicker plates. Steel is inspected when it arrives from the mill, and we keep an inventory of steel on hand to shorten lead times.

The plasma table, which cuts the steel, uses a nesting system to minimize construction waste. Sub arc welding is used to create solid welds through the beams. Each weld is inspected by an AWS and CWB Certified Welding Inspector.

After manufacturing, steel is painted or primed in our shop or sent out for hot dip galvanizing. After all components are manufactured and labeled, they are trucked to the jobsite for installation.

Step 4


Safe, fast, accurate construction is Legacy’s #1 priority. Our process was created by builders and designed to minimize costly surprises and changes at the jobsite.

Two types of installation are available: tech rep installation with one Legacy team member onsite with local crews, or full installation services using factory-trained staff. Both options include start-to-finish service and all specialty tools.


During the post-construction walk-through the construction foreman will educate the building owner on building maintenance and the features of the structure. The foreman will answer any questions before leaving the site.


Once your building is complete, we continue to provide the best customer service in the industry. Our team will conduct a final post project completion visit, and will be on-hand to answer any questions on your new building. As always, our sole objective is your satisfaction.
