1. Calculate both the total product cost (using standard accounting practices) and the relevant cost for this custom job.
2. What is the lowest price at which the tender should be submitted, assuming that Harris Construction wants to make a profit of $200? What will be the impact of such a price on profits reported in the management profits report? What are the opportunity costs of not undertaking this job?
3. Would the lowest price change ifHarris's employees were fully employed with other projects and Harris would need to hire additional staff to handle the job at the same rate as existing employees? Why?
   

P10.9 (Relevant Costs of Labour) Harris Construction Ltd. has been asked to tender for a job to build and install a large customized shed. Harris's estimator has calculated the following costs associated with satisfying the tender: . Variable labour to build the shed in the factory: 25 hours. The cost of staff is $30 per hour, in- cluding all payroll-related costs; however, Harris has insufficient work at the moment to keep its employees busy. . Delivery/installation: 4 hours. This will have to be subcontracted at $50 per hour. . Supervision: Harris always charges 20% of the direct labour in the factory as the cost of supervi- sion. This is an allocation of the costs of the factory manager, storeman, and administration staff. . Materials: The timber needed for the shed is regularly used in the factory. Sufficient timber is held in stock to build the shed. The cost of the timber from the stock records is $1,000, but it will cost $1,100 to replace at current prices. . The shed also needs a metal frame. A suitable frame was purchased 2 years ago for $750 but has never been used. A supplier who saw the frame last week offered Harris $500 for it. Indirect materials (paint, fixings, etc.) will cost about $100. . Overhead: Harris uses a simple method of fixed overhead allocation, charging $250 for every job produced by the factory. . Other costs: Because the customer requires quality certificates for everything it buys, Harris will need to have the completed shed inspected by a registered inspector at a cost of $175
