TxDOT mechanics perform repair and maintenance work during regular business hours.
Private companies do fleet maintenance after hours to reduce the number of vehicles needed.
TxDOT should perform more maintenance after hours and cut fleet costs. Equipment managers, who usually report to management at a level well below District Engineer, must coordinate vehicle upkeep with project requirements. To compensate, fleets must either have redundant equipment available or perform preventive maintenance outside normal hours of operation. Commercial construction fleets generally perform preventive maintenance during evenings and nights to reduce total equipment needed and increase fleet usage. Many private sector employers must pay additional wages to encourage employees to work less desirable schedules.
