Current Alleme Progress Spin Cycle Architecture uses three activity pools to apply overhead to its projects. Each activity has a cost driver used to allocate the overhead costs to the projects. The activities and related overhead costs are as follows: initial concept formation $44,600; design $620,000; and construction oversight $121,800. The cost drivers and estimated use are as follows. Activities Cost Drivers Initial concept formation Number of project changes Design Square feet Construction oversight Number of months (a) Compute the predetermined overhead rate for each activity. Overhead Ra Initial concept formations Design Construction oversights (b) Classify each of these activities as unit-level, batch- level, product-level, or facility-level.
