Styles Brick by Brick (BBB) is a building business that provides a range of building services to the public. Recently it has been asked to quote for garage conversions (GC) and extensions to properties (EX) and has found that it is winning fewer GC contracts than expected. In addition, BBB also produces and sells different types of brick to the construction industry. The three types of brick produced are clay, concrete and reclaimed bricks. 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 costs associated with GC and hence make them more competitive.
