My residential building is past the concept stage and I now need the full detailed design completed in Revit. The model must be taken from its current schematic form to a fully coordinated, construction-ready BIM file, complete with all architectural details and drawing sheets. I will provide the existing concept model, sketches, and design intent. Your task is to refine every architectural element—walls, floors, roofs, stair cores, window and door families, materials, schedules—so the project is ready for tender and construction coordination. Accuracy and clean modelling practice are critical; the file should open without warnings, contain organized work-sets, and follow a clear naming convention.
