CDDI's Surveying Division is comprised of five licensed land surveyors, nine CADD technicians, survey coordinators and eight full time field crews.
The CDDI surveying division provides a wide range of professional Land Surveying services throughout Maryland and the District of Columbia Metropolitan area. The Division consists of four groups:
Each of these groups is capable of functioning independently or in conjunction with one another to suit the project’s needs. CDDI utilizes state-of-the-art technology and software (e.g. Leica, Optech, Sokkia, Autodesk, Bentley, Carlson, etc.) to perform our work accurately and efficiently.
Conventional Surveying:
CDDI’s survey crews utilize cutting edge equipment from Leica, Topcon, Optech, and TDS including state of the art robotic total stations, global positioning systems and a Lidar Scanner.

Heavy Construction Surveying:
CDDI’s Heavy Construction Survey department employs the latest Leica automatic targeting total stations to ensure first order accuracy for construction layout activities. This equipment is supported by cutting-edge software to allow for implementation of the most intricate solutions of architectural design.
The CDDI Heavy Construction Survey department is experienced in the demands of large construction projects. They are mindful of construction schedules and the need for immediate response to the requirements of the Construction Manager.
CDDI‘s Heavy Construction Surveying is overseen by Project Manager Orviel Alam who holds a Bachelor of Science degree in geodetic engineering.

Specialty Surveying Services:
CDDI is equipped with the latest in survey technology and has used it for the most demanding survey situations. CDDI has cutting edge robotic total stations, global positioning systems and a Lidar Scanner.
Robotic Total Stations are mechanized survey equipment allowing the operator to control the instrument from a distance via remote control. This eliminates the need for an assistant staff member to hold the reflector prism over the point to be measured. The operator holds the reflector him/herself and controls the total station instrument from the observed point. This translates to lower cost for CDDI and for our clients as well.
LIDAR is the future of surveying. It is capable of acquiring 500,000 points in one minute. With a vast array of applications, LIDAR can be useful where conventional survey equipment is just not possible to use. CDDI has used this technology in providing WMATA with accurate cross-sections and profiles of their railway tunnels, among other applications.
