Radian Architecture can provide on-going CAD Documentation services. Radian can maintain an on-going record of changes made to your building or site so that you can always have an up-to-date drawing on file. Building and leasing managers typically utilize this service in order to provide them with marketing sheets and to maintain a graphic inventory of vacancies, occupied suites, and floor plans. The Documentation also includes calculating the square footages for each suite and the building total so that every square foot is accounted for.
