POITRA illustrated both concepts with photosimulation in order to compare the alternatives in context.
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. The base photograph was prepared by removing the existing viaduct and restoring the background using traditional digital painting techniques. The piers for the new viaduct that were then partially constructed were left in place to guide the placement of the model viaduct and the ramp alternatives.
Modelers at POITRA then created 3D site models that included the ramp on bridge structure and the ramp on walls. Since the main viaduct was not yet constructed the entire viaduct superstructure also needed to be modeled. The site models included concrete jersey barriers, chain-link splash fencing and mechanically stabilized earth (MSE) wall panels. These models were camera matched, lighted, rendered and composited with the base photograph to create a final photosimulation for each alternative.
CDOT used the finished simulations in meetings with the City and County of Denver and RTD.
