Catch errors in the drawings before work begins

These situations are precisely what is typical of large-scale projects, where the design looks fine on paper, but in reality, conflicts arise between systems. That is why a constructability review is used, which allows the project to be “run through” before construction begins, checking the coordination of architecture, structures, and engineering systems and identifying such errors in advance https://www.fields-builds.com/blog/cutting-costs-avoiding-delays-constructability-reviews the idea is to identify problems at the drawing stage, when fixing them costs the least, rather than during construction, when it leads to stoppages, delays, and additional costs.
