Lubbok Engineering Consultants is a firm of professional civil engineers. The firm obtains its jobs by giving fixed-price quotations, so the profitability depends on the ability predict the time needed to complete all the subtasks necessary for the successful completion of the jobs. Several types of personnel (secretaries, assistants, engineers, senior engineers, managers and partners) work on these jobs for varying amounts of time.

Lubbock engineering has the following budget for 2011:

• Compensation for professional staff: $3,600,000
• Other Costs: $1,449,000

Each professional member must submit a weekly billable time report which is used for charging hours to a client job-order record. In addition, the same time record is used to charge overhead costs for the client job-order record. The firm estimates that 15% of the professional employees time is not billable because they may be involved in continuing education activities, unassigned time, etc. This nonchargeable time is treated as overhead cost.
