Absolutely, you can erect a steel building kit yourself. Our kits come as bolt-together kits with plans you can understand. However, prefab building kits are very large and very heavy. We do recommend some help when erecting. Proper safety equipment is recommended as well as the use of an off-road forklift and scissor lift. Erection times are going to depend on your experience. An experienced erector can erect a 30x40 metal building in 4-7 days.
