POITRA illustrated this concept for two alignments with photosimulation in order to compare the alternatives in context. The location chosen for simulation was at a neighborhood school that had potential visual impacts.
A surprizing percentage of the work on this type of simulation occurs when restoring background elements as foreground elements are removed. Unfortunately all that work usually represents a comparatively small area of the overall simulation. ”

POITRA photographers collected multiple views that would allow the differences in the alternatives to be best described. The Project Engineer made the final view selection. Since two alignments would be simulated two separate base photographs would be required. Each base photograph would have different existing buildings and trees removed and the background restored in addition to removing the existing viaduct and pier columns. This work was accomplished using traditional digital painting techniques.
Modelers at POITRA then created two 3D site models. One modeled the I-70 alignment shift to the north or closer to the school. The other modeled the alignmnent shift south or farther from the school.
The site models included the new viaduct structure, MSE abutment walls and panels, MSE landscape walls and panels, concrete jersey barriers and sound walls. These models were camera matched, lighted, rendered and composited with the appropriately prepared base photograph to create a final photosimulation for each alignment.
CDOT used the finished simulations in I-70 East EIS meetings with the school, the City and County of Denver and area residents during the EIS public process. The simulations also appeared in the Draft EIS document.
