Current Attempt in Progress Bramble Cycle Architecture uses three activity pools to apply overhead to its projects. Each activity has a cost driver used to assign 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 Estimated Use of Cost Drivers per Activity Activities Initial concept formation Design Construction oversight Cost Drivers Number of project changes Square feet 20 155,000 Number of months 105 (a) Compute the predetermined overhead rate for each activity Overhead Rate Initial concept formation 5 per project change Design per square foot Construction oversight Per month b) Classidy each of these activities as unit-level batch-level, product-level, or facility level, Activities Level Initial concept formation Deion Construction over
