Precast concrete is a construction method where concrete elements are made in a controlled factory setting before being transported to construction sites. Think of it like manufacturing very large building blocks - instead of making everything on-site, these pieces are created ahead of time in ideal conditions. This approach is becoming more popular because it saves time, ensures better quality, and reduces on-site work. Similar terms include "prefabricated concrete" or "pre-formed concrete." This method is part of the broader "prefabricated construction" or "modular construction" approach that's changing how buildings are made.
