13:27 MAKE UP MA1.docx Question One a) Brick by Brick (BBB) is a building business that provides a range of building services to the public. Recently they have been asked to quote for garage conversions (GC) and extensions to properties (EX) and have found that they are winning fewer GC contracts than expected. BBB has a policy to price all jobs at budgeted total cost plus 50%. Overheads are currently absorbed on a labour hour basis. BBB thinks that a switch to activity based costing (ABC) to absorb overheads would reduce the cost associated to GC and hence make them more competitive. You are provided with the following data: Overhead Total number category Annual overheads Activity driver of activities per year Supervisors 90,000 Site visits 500 Planners 70,000 Planning documents 250 Property related 240,000 Labour hours 40,000 Total 400,000 A typical GC costs $ 3,500 in materials and takes 300 labour hours to complete. A GC requires only one site visit by a supervisor and needs only one planning document to be raised. The typical EX costs $ 8,000 in materials and takes 500 hours to complete. An EX requires six site visits and five planning documents. In all cases labour is paid $15 per hour. Required: i.
