The percentage of completion for a building project is not displayed until progress has reached 1%, and the scaffolding appears. The building projects in the game vary greatly in their size, and some projects require significantly more time to reach 1% completion, especially if there are few builders working on it. Be patient and allow the builders to continue working, and the scaffolding will appear, allowing you to monitor construction progress. Note that certain projects never display scaffolding or percentage of completion, since they are more complex projects with multiple phases.
