Focus on breaking down the problem into manageable components. Start by considering factors such as the building's expected occupancy, peak usage times, and average wait times for elevators. Use industry standards or benchmarks for elevator capacity and service ratios to support your calculations. Be prepared to discuss how different variables, like the building's purpose (residential vs. commercial), might affect your estimate. Finally, articulate your reasoning clearly, showing how you arrived at your final number.
