All Quonset structures can be erected in a fraction of the time it takes for traditional construction methods. Expect a professional crew to have a 30x40 building erected in 2-4 days and a 40x60 in approx. 4-6 days. If you elect to DIY your construction, it is probably safe to double these times if you have no previous experience with this type of building. Quonset hut kits are pre-fabricated structures that come with all of the necessary materials and instructions for assembly, making them a convenient and cost-effective construction option.
