Architects, visualization experts, zoning approval boards, and developers all benefit when accurate preliminary massing studies are performed in the field. The selection and construction of a new development requires public officials and the local community to fully understand the visual impact trade-offs and design alternatives. To this end, DDIS specializes in balloon tests and visual impact simulations, which are often required to give a general sense of a proposed structures, such as Data centers. This includes potential mapping and visualizing fiber lines, transmission lines, substations, transportation centers,etc. . The balloon tests give a physical demonstration of visibility and sight-lines, and the visual impact simulations overlay a model of the proposed structures over a high-resolution aerial photograph, showing the proposed structure within the existing backdrop.
