In North Texas, layout issues rarely arrive as one dramatic mistake. They show up as micro drift that compounds across a corridor or open lobby, then gets amplified by raking light and punch-list pressure. If the crew has to stop constantly to "confirm the grid," production slows, and the finish still looks inconsistent. The smarter move is a repeatable spacing routine that holds the module steady while installers keep moving. In this article, we will discuss the habits that prevent drift and keep corrections off the critical path.
