Residential renovation projects often fail for predictable reasons: unclear scope, fragmented coordination, weak documentation, and budget decisions made too late. This technical guide presents the STQC Renovation Workflow-a repeatable operational model designed to make renovation projects more transparent, controllable, and financially disciplined. Built for the US market and real-world jobsite conditions, the model translates project delivery into a clear sequence of stages with defined inputs, checkpoints, and responsibilities. Readers get a practical framework for planning, procurement, execution, quality control, and closeout-so that time, cost and expectations are managed proactively rather than repaired after the fact. Inside you will find: - a structured end-to-end workflow for residential renovation; - governance and documentation practices that reduce disputes and rework; - budgeting and change-control logic that protects margin and the client's trust; - guidance on supply chain coordination to prevent delays and overspending.
