Importantly, the space around the PVM must be sufficient enough to provide temporary storage of materials and prefinished components, such as windows, which are manhandled or lifted by an overhead crane. The rate of construction is controlled by the availability of personnel to perform the specialist tasks at the required time. As a result, the process can be relatively slow, but conversely, the critical path, in this case, is not reliant upon the completion of any one task. When completed, the PVM units are lifted using an overhead crane and either stored temporarily or transported to the project site (Figure 12).
