If you have built a site-built home before, you are not likely familiar with what a set crew does or why a crane operator is important. These facets are unique to the modular home industry, and they are extremely important. The set crew is important in placing the modules onto the foundation and securing them into place accurately. And without an expert crane operator, there is no way to lift the modules off the tractor-trailer truck and onto your building site.
Upon the arrival of the set crew, the set crew chief inspects the foundation for manufacturer's compliance and for any defects. Once inspected, the set crew guides and secures each module into place and removes transportation material from each module.
The crane operator should be experienced in placing modular homes so that proper attachments to the modules do not damage the sections inadvertently. Set crews of course assist with this, but it helps to have a knowledgeable crane operator as they are quite informative on stuff like crane examination, etc.
Ideally, the crane operator has already surveyed your site prior to the arrival of the modular units and knows exactly where he can set up the crane. The terrain and access should be cleared as part of your excavation to allow enough room for the crane to arrive and locate itself for your modular home placement.
Most "sets" take either one or two days to complete depending on the home's size and complexity of the design. Because the modular must be unwrapped from transport and connected together while exposed, weather can influence the assembly. But assuming a good forecast, the modular home set usually proceeds quickly and smoothly. By the time the set crew leaves, your home looks as if it was built on-site practically overnight.
