ANSWER:

Formulas for increasing staffing needs are primarily derived from monitoring and analyzing the backlog of uncompleted maintenance and repair work orders along with customer satisfaction feedback.  The increasing age of facilities and mechanical systems is a known and contributing factor in the growth of backlogs of maintenance and repair, but it is not used directly in computing staffing needs.  The Division of Maintenance does not have the supervisory or on-the-job training capacity to increase the number of participants in the HVAC Apprenticeship Program beyond the current level of four apprentices.
