   Division of Transportation Engineering  



The Construction Section of the Division of Transportation Engineering is responsible for the advertisement, construction and quality assurance of new capital improvement projects as well as improvements to existing transportation facilities including roads, bridges, bikeways and pedestrian facilities.

The Construction Section achieves its core mission of delivering construction projects on time, under budget, and meeting the desired scope/quality with the help of dedicated staff, consultants and construction contractors. The Construction Section is made up of three units - a Contracts team, a Construction Management/Inspection group and a Materials Control Center. These units consist of Engineers, Construction Managers, Construction Inspectors, Material Inspectors and Administration Staff.

The following figure shows a typical life cycle of a capital improvement construction project:

Please note that roadway construction in Montgomery County is also undertaken by other agencies and private entities such as the Maryland State Highway Administration , local municipalities, developers, and home owners associations who have similar roadway construction and maintenance responsibilities.

Normal maintenance of County roads is the responsibility of the Division of Highway Services. For more information about maintenance activities, please click here.
