The Administration and Client Engineering Services (ACES) is responsible for providing a variety of services for Department of Transportation and Engineering as well as many other city agencies. A majority of the interagency services include surveying and civil engineering design; however, ACES also provides in-house support in the areas of Information Technology, Files, Technical Records, Accounting, Human Resources and Administration.

The ACES client engineering group provides professional services to many Departments, including Community Development, Health, Law, General Services, and the Southwest Ohio Regional Transit Authority. Therefore, many of the program objectives of the Client Engineering group respond to the capital program needs of other General and Enterprise Fund agencies, as well as the Transportation and Engineering Department itself.
