Testimonials
The whole engineering phase with Legacy was excellent.
They were very responsive to our ideas and turned things around very quickly. Even the installation was fast—the whole building was erected in about seven days. The fabric roof allows a lot of natural light into the building, which is a big advantage on the operations floor, since it reduces our need for artificial lighting inside. It provides significant sheltering from rain, wind and cold. Even though we didn't have it insulated, it's still noticeably more comfortable inside during the winter. The structure actually provides more of a shading and cooling effect. The Legacy building has performed at or above expectations in many ways. And on top of its functionality within our process, it offers environmentally friendly features in its own right. It's a great system for our application.
We were very impressed by their engineering team.
By today's standards, the buildings we're designing are of world-class caliber in the U.S. and Canada. Legacy offered several features that put them at the top of the list. They are unique among fabric buildings in that they build on a rigid steel frame. Everything looked good, from the eave and ridge ventilation system to the method for installing fabric panels. Combined with material delivery times and the time to construct, Legacy seemed like the perfect choice for our application. "The whole design is very efficient for our operations. Flexibility is key, especially when the building is a 'first of its kind' for the industry. We had one design change after the whole plan was in place, to widen our trapeze in the structure that supports the conveyor, and Legacy was able to make that change without any problem. The conveyor system fits and operates just as it was designed. "Legacy knew our schedule and saved us over 30 days of downtime. They stood the frames for the entire fabric structure in a single day, and everything - conveyors, electrical, fabric - was completed within five weeks of them coming to the site. It was a Herculean effort on Legacy's part. It was fantastic. They have a very passionate team, from top to bottom. In all respects, from design to pricing to production, Legacy is one of the best building contractors I've ever worked with. I look forward to working with them again.
The Legacy construction crew was very professional and courteous.
Because of our soil issues, we simply couldn't afford to construct a more traditional building. The concrete costs made a more traditional building cost prohibitive. The lightweight design of our Legacy building allowed us to reach a compromise between soil conditions and cost. Regarding the design and construction phases of the building, I can say that the process went exceptionally well. When I made eleventh-hour changes to the job, Legacy handled them with ease. They finished the job well ahead of schedule, worked safely, and followed our stringent safety requirements to the letter.
