摘要： The present invention relates to a modular assembly, a site factory, for at least partially enclosing a site during construction of a structure. The modular assembly comprising: a plurality of portal frames, each portal frame comprising two columns and a roof beam, each column and roof beam comprising a plurality of pre-assembled units; a jack-up frame for each column; at least two first rails, each of the first rails being mounted to at least one of the roof beams; at least one second rail slidably mounted to the at least two first rails; and a plurality of panels of a flexible material configured to provide a full enclosure of the site and mounted above the roof beam. The or each second rail is configured to slidably receive at least one lifting device. The pre-assembled units are configured to be connected on site, and lifted using said jack-up frames, to form the portal frames, and wherein each first rail, and the or each second rail are configured to be mounted on the portal frames on site.
