I watched the Bilt steps a couple times before the actual install effort. It estimated 3 people at 10 hours. Not sure where that came from as it took 3 of us about 4 hours to complete. My guess is maybe if you did all the bolts by hand versus a power tool. Having 3 people with 3 power tools made it go pretty quick. We also carefully inventories and staged all the materials near the install site. Instructions were pretty easy to follow. We only ran into one issue were we assembled the corner braces incorrectly and had to back a few pieces out to fix.
