Division of Maintenance

Maintenance worker placing patch

District-level personnel in need of technical assistance should contact Central Office Maintenance Field Engineers, who are available to help. Field Engineers serve as operational representatives for particular subject-matter areas and may also be assigned special functions.

Section Engineers and District Maintenance Staff should always remember that the Division of Maintenance’s responsibility is to maintain – not improve – a facility. Maintenance funds should not be used to improve highway facilities except for incidental improvements that are the direct outcome of a maintenance activity. For example, replacing a damaged drain pipe represents an improvement, but it may also be the only feasible repair option. 

Section Engineers and District Maintenance staff may consult Field Engineers for a wide variety of support functions. These functions are described in this Knowledge Book.

1. Permits
