I anticipate that the modelling stage will take the longest to achieve because I predict that we will have difficulty in reading areas of the plan and elevation drawings. Rendering will take a while too as we plan to add an occlusion render over the top of the colour/ texture layer. Occlusion always takes a while to render out. I have perhaps over estimated how long the pre-production stage will take. Preferably we will want to begin modelling the hotel as quickly as possible.
